Abstract
The utility model relates to an utility knife adjusting device which comprises a wenge handle. The wenge handle is arranged on an outer shell of the utility knife. A plurality of opening locking grooves are arranged on one side of the wenge handle. A lower adjusting piece is arranged above the wenge handle in a movable mode. A bulging portion coordinated with a blade fixing hole is arranged on the front end of the lower adjusting piece. A locking piece and clips are arranged in the lower adjusting piece in a movable mode. Two locking feet are arranged at the upper end of the locking piece and the two locking feet coordinate with the locking grooves. The tail ends of two arms of the clips contradict with the inner wall of the lower adjusting piece. The top portion of the clips contradicts with the bottom of the locking piece. A movable upper adjusting piece is arranged above the lower adjusting piece. Two pushing grooves are arranged on one side of the upper adjusting piece and the two pushing grooves respectively correspond to places of the two locking feet. The inner walls of groove openings contradict with the outer walls of the locking feet. The utility knife adjusting device is large in locking force, stable in structure, and little in required parts. Manufacturing cost is reduced. The utility knife adjusting device is not subject to limits of sizes of the utility knife. The utility knife adjusting device is wide in application range and beautiful in profile.
Description
Technical field
The utility model relates to the cutter field, refers to especially a kind of cutter adjuster.
Background technology
More common cutter controller structure as shown in Figure 2 in the market, mainly comprise adjusted piece 1, lower regulating block 2 and back-moving spring, be provided with clamping block 5 and the clamping block spring 6 that matches with lock slots 4 on the iron handle of a knife 3 at lower regulating block 2, it is inconsistent with clamping block 5 respectively to be provided with 7, two inclined-planes 7, two inclined-planes in adjusted piece 1 and clamping block 5 corresponding positions.
During locking, when adjusted piece 1 and lower regulating block 2 were failure to actuate, clamping block 5 was stuck in the lock slots 4 under the elastic force of clamping block spring 6, realized locking.
When feed or withdrawing, finger presses adjusted piece 1 advances adjusted piece 1 or retreats, and the inclined-plane 7 on the adjusted piece 1 promotes clamping blocks 5, make clamping block 5 overcome spring force, regulating block 2 directions move downwards, thereby break away from iron handle of a knife 3, so that lower regulating block 2 moves forward or retreats, when entering into next lock slots 4, clamping block 5 sticks in the next lock slots 4 under the elastic force effect of clamping block spring 6, and lower regulating block 2 also resets under the effect of back-moving spring.
This adjuster is in the situation of large cutting force, and latching force is subjected to the impact of the lock slots degree of depth, if lock slots is dark not, then is easier to occur clamping block and breaks away from, and then blade is skidded off without early warning, easily cause danger; And promoting clamping block with spring is locked in the lock slots, because the maximum compressibility of spring is 30 percent of drift, so it is darker that tooth is done, the clamping block stroke is longer, and spring will be longer, and the width of lower regulating block usually is subject to the restriction of structure and size, cause this adjuster can not be applicable to the cutter of all size, in addition, this controller structure is complicated, number of spare parts is more, and manufacturing cost is higher.
The utility model content
Technical problem to be solved in the utility model is: preferably cutter adjuster of wider, the simple in structure and locking effect of a kind of scope of application is provided.
For addressing the above problem, the technical solution adopted in the utility model is: the cutter adjuster, comprise the iron handle of a knife that is arranged on the cutter shell, iron handle of a knife one side is provided with the lock slots of several openings, iron handle of a knife top is movably set with lower regulating block, lower regulating block front end is provided with the protuberance that matches with the blade fixing hole, be movably set with clamping block and shell fragment in the lower regulating block, the clamping block upper end is provided with two locking pin, the locking pin matches with lock slots, shell fragment two arms are terminal inconsistent with lower regulating block inwall, shell fragment top and clamping block bottom are inconsistent, and lower regulating block top is provided with movable adjusted piece, and adjusted piece one side is provided with two and promotes groove, two promotion grooves are corresponding with the positions of two locking pin respectively, and the notch inwall is inconsistent with locking pin outer wall.
Described promotion groove notch is towards the locking pin, and wide outside and narrow inside, notch both sides inwall is two inclined-planes.
Described clamping block bottom is provided with groove, and the shell fragment top is provided with circular-arc projection, and groove matches with projection.
The beneficial effects of the utility model are: above-mentioned cutter adjuster, and latching force is large and structure is more stable, and required part is few, has reduced the cost of making, and is not subjected to the restriction of cutter size, and the scope of application is wider, and profile is also more attractive in appearance.

The specific embodiment
Below by specific embodiment the utility model cutter adjuster is described in further detail.
As shown in Figure 1, the cutter adjuster, comprise the iron handle of a knife 1 that is arranged on the cutter shell, iron handle of a knife 1 one sides are provided with the lock slots 2 of several openings, iron handle of a knife 1 top is movably set with lower regulating block 3, lower regulating block 3 front ends are provided with the protuberance 4 that matches with the blade fixing hole, be movably set with clamping block 5 and shell fragment 6 in the lower regulating block 3, clamping block 5 upper ends are provided with two locking pin 7, locking pin 7 matches with lock slots 2,6 liang of arms of shell fragment are terminal inconsistent with lower regulating block 3 inwalls, shell fragment 6 tops and clamping block 5 bottoms are inconsistent, and lower regulating block 3 tops are provided with movable adjusted piece 8, and adjusted piece 8 one sides are provided with two and promote groove 9, two promotion grooves 9 are corresponding with the positions of two locking pin 7 respectively, and the notch inwall is inconsistent with locking pin 7 outer walls.
Described promotion groove 9 notches are towards locking pin 7, and wide outside and narrow inside, notch both sides inwall is two inclined-planes.
Described clamping block 5 bottoms are provided with groove 10, and shell fragment 6 tops are provided with circular-arc protruding 11, and groove 10 matches with projection 11.
During locking, adjusted piece 8 and lower regulating block 3 all are failure to actuate, and locking pin 7 is stuck in the lock slots 2 under shell fragment 6 motive forces, realizes locking; When feed or withdrawing, finger presses adjusted piece 8, adjusted piece 8 is advanced or retreat, promotion groove 9 on the adjusted piece 8 promotes locking pin 7, and it is mobile that locking pin 7 is overcome in the downward regulating block 3 of shell fragment 6 elastic force, thereby go out of lock groove 2, lower regulating block 3 is advanced or retreat, when entering into next lock slots 2, locking pin 7 snaps in the lock slots 2 under the effect of shell fragment 6 power.
The above embodiments are principle and the effect thereof of illustrative the invention only, and the embodiment of part utilization, but not is used for restriction the utility model; Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
