Abstract
The utility model discloses a kind of screwdriver rubber sleeve, including body, boss is connected with the madial wall of body, the outer surface top end of body is provided with projection.The utility model is raised by being set in the outer surface top end of rubber sleeve body, can increase the frictional force between the rubber sleeve and screw, help smoothly to screw the screw of stripped thread；By being symmetrical arranged at least two groups of boss on the madial wall of body, the frictional force between rubber sleeve and screwdriver can be increased so that fastening is not easy to fall down when the rubber sleeve is enclosed on driver bit；By opening up small through hole at the top dead center position of body, during the rubber sleeve is enclosed on into driver bit, the air in rubber sleeve is discharged by small through hole, rubber sleeve is more fastened；By setting annular rib on the outer surface of body, the frictional force between the rubber sleeve and human hand can be increased when user removes rubber sleeve, conveniently remove rubber sleeve.
Description
Technical field
The utility model belongs to mechanical assistance technical field of tools, and in particular to a kind of screwdriver rubber sleeve.
Background technology
In daily life and mechanical equipment installation are safeguarded, we always touch screw every now and then." stubborn screw " is usual
For be very simple, still, the groove inner wall that screw easily causes screw tail cap due to screwing repeatedly is destroyed and occurred
Stripped thread, when running into the screw of " stripped thread ", " stubborn screw " will become a very laboriously difficult matter.If rely solely on tradition
Screwdriver be difficult then the screw for screwing stripped thread.
Utility model content
The purpose of this utility model is to provide a kind of screwdriver rubber sleeve, and the groove inner wall for solving screw tail cap occurs to break
The problem of screw is difficult to screw after bad.
Technical scheme is used by the utility model：A kind of screwdriver rubber sleeve, including body, the madial wall of body
On be connected with boss and be used to increase frictional force between the rubber sleeve and screwdriver, the outer surface top end of body is provided with projection
For increasing the frictional force between the rubber sleeve and screw.
The characteristics of the utility model, also resides in：
Projection is yi word pattern or cross.
The longitudinal section of boss is triangle of the drift angle towards body axis, and boss is at least symmetrically set on the madial wall of body
Put two groups, every group at least provided with two.
Small through hole is provided with the top dead center position of body.
Annular rib is provided with the outer surface of body.
The beneficial effects of the utility model are：A kind of screwdriver rubber sleeve of the present utility model, by rubber sleeve sheet
The outer surface top end of body sets projection, can increase the frictional force between the rubber sleeve and screw, help smoothly to screw cunning
The screw of silk；By being symmetrical arranged at least two groups of boss on the madial wall of body, can increase between rubber sleeve and screwdriver
Frictional force so that when the rubber sleeve is enclosed on driver bit fastening be not easy to fall down；By at the top dead center position of body
Small through hole is opened up, during the rubber sleeve is enclosed on into driver bit, the air in rubber sleeve is discharged by small through hole,
Rubber sleeve is set more to fasten；, can be when user removes rubber sleeve by setting annular rib on the outer surface of body
Increase the frictional force between the rubber sleeve and human hand, conveniently remove rubber sleeve.
Brief description of the drawings
Fig. 1 is a kind of cross section structure diagram of screwdriver rubber sleeve of the utility model；
Fig. 2 is a kind of overlooking the structure diagram of screwdriver rubber sleeve of the utility model；
Fig. 3 is a kind of main structure diagram of screwdriver rubber sleeve of the utility model.
In figure, 1. bodies, 2. boss, 3. is raised, 4. small through hole, 5. annular ribs.
Embodiment
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings：
A kind of screwdriver rubber sleeve of the present utility model, as shown in Figure 1 and Figure 2, including body 1, the madial wall of body 1
On be connected with boss 2 and be used to increasing frictional force between the rubber sleeve and screwdriver, the outer surface top end of body 1 is provided with convex
Play 3 to be used to increase the frictional force between the rubber sleeve and screw, projection 3 is yi word pattern or cross.The longitudinal section of boss 2 is
Drift angle towards the axis of body 1 triangle, boss 2 be at least symmetrical arranged on the madial wall of body 1 two groups, every group at least provided with
Two.Small through hole 4 is provided with the top dead center position of body 1.As shown in figure 3, it is convex to be provided with ring-type on the outer surface of body 1
Line 5.
When needing to screw the screw of stripped thread, the rubber sleeve is enclosed at the cutter head of screwdriver first, then with outside body 1
The groove for the contact screw tail cap of projection 3 that surface top end is set, used originally rubber just can increasing friction force, along with convex
3 are played, the frictional force between the rubber sleeve and screw is further increased, helps smoothly to screw the screw of stripped thread.This practicality is new
In the screwdriver rubber sleeve of type, at least two groups of boss 2 are symmetrical arranged on the madial wall of body 1, can increase rubber sleeve with
Frictional force between screwdriver so that fastening is not easy to fall down when the rubber sleeve is enclosed on driver bit；At the top center of body 1
Opening position opens up small through hole 4, and during the rubber sleeve is enclosed on into driver bit, rubber sleeve is discharged by small through hole 4
Interior air, makes rubber sleeve more fasten；Annular rib 5 is set on the outer surface of body 1, rubber can be removed in user
Increase the frictional force between the rubber sleeve and human hand during gum cover, conveniently remove rubber sleeve.
