Description

A kind of adjuster of art knife

Technical field

The present invention relates to cutter field, refer to a kind of adjuster of art knife especially.

Background technology

Adjuster of art knife more common in the market, mainly comprise regulating block, lower regulating block and back-moving spring, lower regulating block is provided with the clamping block and clamping block spring that match with the lock slots on handle of a knife, be provided with two inclined-planes in the position that upper regulating block is corresponding with clamping block, two inclined-planes are inconsistent with clamping block respectively.

During locking, when upper regulating block and lower regulating block are failure to actuate, clamping block, under the elastic force of clamping block spring, is stuck in lock slots, realizes locking.

When feed or withdrawing, regulating block in finger presses, makes regulating block advance or retreats, the slope driving clamping block on upper regulating block, clamping block is made to overcome spring force, downward regulating block direction is moved, thus departs from handle of a knife, lower regulating block is moved forward or retreats, when entering into next lock slots, clamping block, under the elastic force effect of clamping block spring, sticks in next lock slots, and lower regulating block also resets under the effect of back-moving spring.

This adjuster is when large cutting force, and latching force, by the impact of the lock slots degree of depth, if lock slots is dark not, is then easier to occur that clamping block departs from, and then blade is skidded off without early warning, easily cause danger; And use spring to be locked in lock slots to promote clamping block, maximum compressibility due to spring is 30 percent of drift, so tooth do darker, clamping block stroke is longer, and spring will be longer, and the width of lower regulating block is usually 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 more complicated, number of parts is more, and manufacturing cost is higher.

Summary of the invention

Technical problem to be solved by this invention is: provide that a kind of scope of application is comparatively wide, structure simple and the good a kind of adjuster of art knife of locking effect.

For solving the problem, the technical solution used in the present invention is: a kind of adjuster of art knife, comprise the handle of a knife be arranged on cutter shell, several lock slots are provided with in handle of a knife, lower regulating block is movably set with above handle of a knife, lower regulating block front end is provided with the protuberance matched with blade fixing hole, clamping block groove is provided with in lower regulating block, the clamping block of T font is movably set with in clamping block groove, match with lock slots in the lower end of clamping block, movable upper regulating block is provided with above lower regulating block, upper regulating block both sides are respectively arranged with one and promote groove, promote groove notch wide outside and narrow inside, pocket bottom is the plane matched with clamping block, notch both sides inwall is inclined-plane, shell fragment is provided with between upper regulating block and lower regulating block, shell fragment two-arm end and upper regulating block inwall inconsistent, with clamping block top phase lock fit bottom shell fragment, also resetting means is provided with in upper regulating block.

Described lock slots is blind bore type structure, and lock slots matches with clamping block.

Be provided with square groove bottom described shell fragment, groove inner wall matches with clamping block upper end outer wall.

Described resetting means comprises and is arranged on two jig arm on regulating block and reset bar, and reset bar is made up of elastomeric material, and reset bar two ends are fixed on the inwall of lower regulating block both sides, and two jig arm are separately positioned on reset bar both sides, and inconsistent with reset bar.

The invention has the beneficial effects as follows: above-mentioned a kind of adjuster of art knife, latching force is large and structure is more stable, and required part is few, reduces the cost of manufacture, and not by the restriction of cutter size, the scope of application is wider, and profile is also more attractive in appearance.

Detailed description of the invention

Below by specific embodiment, a kind of adjuster of art knife of the present invention is described in further detail.

As Fig. 1, a kind of adjuster of art knife shown in Fig. 2 and Fig. 3, comprise the handle of a knife 1 be arranged on cutter shell, several lock slots 2 are provided with bottom handle of a knife 1 in the present embodiment, lock slots 2 also can be arranged on the side of handle of a knife 2, lower regulating block 3 is movably set with above handle of a knife 1, lower regulating block 3 front end is provided with the protuberance 4 matched with blade fixing hole, clamping block groove 5 is provided with in lower regulating block 3, the clamping block 6 of T font is movably set with in clamping block groove 5, match with lock slots 2 in the lower end of clamping block 6, movable upper regulating block 7 is provided with above lower regulating block 3, upper regulating block 7 both sides are respectively arranged with one and promote groove 8, promote groove 8 notch wide outside and narrow inside, pocket bottom is the plane matched with clamping block 6, notch both sides inwall is inclined-plane, shell fragment 9 is provided with between upper regulating block 7 and lower regulating block 3, shell fragment 9 two-arm end and upper regulating block 7 inwall inconsistent, with clamping block 6 top phase lock fit bottom shell fragment 9, resetting means 10 is also provided with in upper regulating block 7.

Described lock slots 2 is blind bore type structure, and lock slots 2 matches with clamping block 6.

Be provided with square groove 11 bottom described shell fragment 9, groove 11 inwall matches with clamping block 6 upper end outer wall.

Described resetting means 10 comprises and is arranged on two jig arm 12 on regulating block 7 and reset bar 13, reset bar 13 is made up of elastomeric material, reset bar 13 two ends are fixed on the inwall of lower regulating block 3 both sides, and two jig arm 12 are separately positioned on reset bar 13 both sides, and inconsistent with reset bar 13.

During locking, upper regulating block 7 and lower regulating block 3 are all failure to actuate, and clamping block 6 is stuck in lock slots 2 under shell fragment 9 motive force, realize locking, when feed or withdrawing, regulating block 7 in finger presses, regulating block 7 is made to advance or retreat, promotion groove 8 slope driving clamping block 6 on upper regulating block 7, clamping block 6 is overcome in the downward regulating block 3 of shell fragment 9 elastic force move, thus the groove 2 that goes out of lock, lower regulating block 3 is made to advance or retreat, descend the jig arm 12 on regulating block 3 advance or retreat simultaneously, reset bar 13 is made to produce deformation, when entering into next lock slots 2, clamping block 6 is under the effect of shell fragment 9 motive force, snap in lock slots 2, the propulsive thrust of reset bar 13 makes jig arm 12 retreat or advance, thus drive upper regulating block 7 to reset.

The above embodiments are the principle of illustrative the invention and effect thereof only, and the embodiment that part is used, but not for limiting the present invention; It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
