The invention provides a kind of hand held rotation and unloads instrument, including handle, shell, bearing, mobile jib and driver bit；It is provided with gear, tooth bar in shell, drives bevel gear, driven wheel of differential, rotary shaft；Handle is located at above shell, and lower surface is fixing with tooth bar upper surface to be connected；Tooth bar inserts shell gear phase toe joint also and in rotary shaft；Being provided with spring between tooth bar and handle, spring is positioned at outside shell；Shell divides forward and backward two parts, is connected by screw therebetween.Instrument is unloaded in the hand held rotation of the invention, after cutter head inserts screw, by reciprocal kneading action, drives mobile jib to rotate multi-turn, thus Quick fastening or back out screw.
Description
Technical field
The invention belongs to hardware & tools field, especially relates to a kind of hand held rotation and unloads instrument.
Background technology
Screwdriver is one of commonly used instrument of people's daily life, is mainly used to tighten or unclamp screw.The most at present
On market for seen screwdriver, its hands is being fixed as one with mobile jib, during operation, rotates hands handle, makes mobile jib turn round
Motion, so that screw-driving or exit object, though this normal screws cutter is the most durable, but uses clumsiness, and efficiency is low.The fullest
The productive life rhythm that foot does not constantly accelerate instantly.Existing electronic, pneumatic screw driver speed fast work efficiency height, but price is held high
Expensive, and need during work to connect electric wire or air pump, use loaded down with trivial details and restricted, dangerous, it is only applicable to factory and specialty is repaired
Shop, it is difficult to serve the general public.And Universal-purpose screwdriver adds the cutter head of different size, extend range, but with general when using
Logical screwdriver is similar to, and work efficiency is the highest.
Summary of the invention
In view of this, the invention is directed to the rotation of a kind of hand held and unloads instrument, in order to Quick fastening or back out screw,
Mobile jib can be realized without swing handle and do gyration.
For reaching above-mentioned purpose, the technical scheme of the invention is achieved in that
A kind of hand held rotation unloads instrument, including handle, shell, bearing, mobile jib and driver bit；It is provided with tooth in described shell
Wheel, tooth bar, drive bevel gear, driven wheel of differential, rotary shaft；Described handle is located at above described shell, lower surface and described tooth
Bar upper surface is fixing to be connected；Described tooth bar inserts shell gear phase toe joint also and in rotary shaft；Described driving bevel gear is located at
In rotary shaft on the left of gear, and engaged by gear with the driven wheel of differential of its lower end；Shell is stretched out at described rotary shaft two ends；
Described bearing is arranged at the shell left and right sides in the groove of rotary shaft end；Described rotary shaft passes described bearing；Described
Mobile jib upper end is built in described shell, is connected with driven wheel of differential lower surface；Shell is extended in described mobile jib lower end, with screw
Cutter head is connected.
Further, being provided with spring between described tooth bar and handle, described spring is positioned at outside shell.
Further, described shell divides forward and backward two parts, is connected by screw therebetween.
Relative to prior art, a kind of hand held rotation described in the invention is unloaded instrument and is had the advantage that
Utilize mechanical drive principle, wrist twisting actions when replacing old-fashioned screwdriver to use by finger kneading action.
By the cooperation of rack and pinion, tooth bar vertical motion is converted into the rotation of axle；By cooperating between bevel gear, can
The rotation of axle is passed to mobile jib, and then drives mobile jib to rotate.After driver bit inserts screw, only need reciprocal kneading action, no
With extracting cutter head, mobile jib can be made to rotate multi-turn, thus realize Quick fastening or back out the purpose of screw, service efficiency is very
High.
Accompanying drawing explanation
The accompanying drawing of the part constituting the invention is used for providing being further appreciated by the invention, and the present invention creates
The schematic description and description made, for explaining the invention, is not intended that the improper restriction to the invention.?
In accompanying drawing:
Fig. 1 is the structural representation described in the invention embodiment；
Description of reference numerals:
1-handle, 2-shell, 3-spring, 4-gear, 5-tooth bar, 6-drives bevel gear, 7-driven wheel of differential, 8-mobile jib,
9-bearing, 10-screw, 11-driver bit, 12-rotary shaft.
Detailed description of the invention
It should be noted that in the case of not conflicting, the embodiment in the invention and the feature in embodiment can
To be mutually combined.
Describe the invention below with reference to the accompanying drawings and in conjunction with the embodiments in detail.
As it is shown in figure 1, a kind of hand held rotation unloads instrument, including handle 1, shell 2, bearing 9, mobile jib 8 and driver bit 11；
It is provided with gear 4, tooth bar 5 in shell 2, drives bevel gear 6, driven wheel of differential 7, rotary shaft 12；Handle 1 is located at above shell 2, under
End face is fixing with tooth bar 5 upper surface to be connected；Tooth bar 5 inserts shell gear 4 phase toe joint also and in rotary shaft 12；Drive bevel gear
6 are located in the rotary shaft 12 on the left of gear 4, and are engaged by gear with the driven wheel of differential 7 of its lower end；Rotary shaft 12 two ends are stretched
Go out shell 2；Bearing 9 is arranged at shell 2 left and right sides in the groove of rotary shaft 12 end；Rotary shaft 12 is through bearing 9；Main
Bar 8 upper end is built in shell 2, is connected with driven wheel of differential 7 lower surface, and shell 2 is extended in mobile jib 8 lower end, with driver bit
11 are connected.Being provided with spring 3 between tooth bar 5 and handle 1, spring 3 is positioned at outside shell 2.Mobile jib 8 one end and driven wheel of differential 7 phase
Even, the other end stretches out shell 2, is connected with driver bit 11.2 points of forward and backward two parts of shell, therebetween by screw 10
Connect.
During use, opening the switch blocking tooth bar 5 on shell 2, tooth bar is ejected to outer spring, will indicate the one of " tightly " word
Side shell 2 is close at the palm of the hand, and driver bit 11 is vertically inserted in screw head, holds shell 2, and finger inwardly mediates tooth bar 5, tooth bar
5 move downward, and tooth bar 5 coordinates with gear 4, vertical motion is converted into axle and rotates, and the rotation of rotary shaft 12 drives and drives cone
Gear 6 rotates, and by driving bevel gear 6 and the engagement of driven wheel of differential 7, passes motion to driven wheel of differential 7, and then drives
The mobile jib 8 being connected with driven wheel of differential 7 does gyration.
Mediate complete, only need to repeat kneading action, treat that screw-driving can stop.
When need to loosen the screw a little, the side shell 2 indicating " loose " word is close at the palm of the hand, repeats finger kneading action.
Use complete, tooth bar 5 is mediated shell 2 internal, promote the switch on shell 2,5, tooth is blocked.
The foregoing is only the preferred embodiment of the invention, not in order to limit the invention, all at this
Within the spirit of innovation and creation and principle, any modification, equivalent substitution and improvement etc. made, should be included in the invention
Protection domain within.
