Abstract
The utility model discloses an antiskid screwdriver, including screwdrivers blade, screwdrivers blade's preceding terminal surface is a plane, screwdrivers blade have at least a pair of with screwdrivers blade's axis central symmetry setting and to screwdrivers blade's the circular arc reverse slope that the axis direction is sunken, the lower limb of each circular arc reverse slope is connected to on the periphery of screwdrivers blade's preceding terminal surface. The utility model discloses a last circular arc reverse slope that is provided with of screwdrivers blade is formed with the dihedral degree between circular arc reverse slope and the preceding terminal surface, during rotating screwdrivers blade, need not to exert too big perpendicular decurrent power to screwdrivers blade in the recess on screwdrivers blade's front end embedding screw head, can twist the screw, and screwdrivers blade can not follow the recess on the circular arc reverse slope roll -off screw head yet.
Description
Technical field
This utility model relates to driver technology field, particularly relates to a kind of slip-proof screwdriver.
Background technology
Seeing Fig. 1, be given in figure is existing screwdriver, including driver bit 10, driver bit 10
Front end there is at least one pair of be symmetrical arranged and from top to bottom to screwdriver with the axis 12 of driver bit 10
Inclined-plane 11a, 11b that axis 12 direction of 10 tilts, during use, the front end alignment of driver bit 10
Groove 21a on the head 21 of screw 20 also embeds in the groove 21a on the head 21 of screw 20,
Driver bit 10 is applied power vertically downward turn driver bit 10 so that the screw 20 tightened revolves
Go out screw hole or by screw 20 DRIVE SCREWS hole.If but driver bit 10 is applied vertically downward
Power is not enough, is easily caused driver bit 10 along inclined-plane 11a or 11b during turn driver bit 10
Skid off, this screwdriver use time waste time and energy, and be easily caused on the head 21 of screw 20 recessed
Groove 21a is deformed, and affects screw 20 subsequent use effect.
To this end, applicant carried out useful exploration and trial, have found result of the above problems,
Technical scheme described below produces under this background.
Utility model content
Technical problem to be solved in the utility model: there is time-consuming expense when using for existing screwdriver
The problem that power, the groove being easily caused on screw head are deformed, a kind of time saving and energy saving and energy of existing offer
The slip-proof screwdriver of the situation that screw head is deformed when enough avoiding using.
This utility model is solved the technical problem that to realize by the following technical solutions:
Slip-proof screwdriver, including driver bit, it is characterised in that the front end face of described driver bit is one
Plane, described driver bit have at least one pair of be symmetrical arranged with the axis centre of described driver bit and to
The circular arc reverse slope of the axis direction depression of described driver bit, the lower limb of each circular arc reverse slope connects
To the periphery of the front end face of described driver bit.
In a preferred embodiment of the present utility model, described driver bit is yi word pattern structure, its tool
There is circular arc reverse slope described in a pair.
In a preferred embodiment of the present utility model, described driver bit is cross-shaped configuration, its tool
Have two to described circular arc reverse slope.
Owing to have employed technical scheme as above, the beneficial effects of the utility model are: this utility model
Driver bit on be provided with circular arc reverse slope, be formed with Reverse gantry between circular arc reverse slope and front end face,
When also turn driver bit in the front end of driver bit embeds the groove on screw head, it is not necessary to screw
Cutter head applies excessive power vertically downward, can turn screw, and driver bit also will not be along circular arc backslash
Face skids off the groove on screw head.This utility model simple in construction, time saving and energy saving, and be effectively prevented from
Groove on screw head is deformed, it is ensured that screw subsequent use effect.

Detailed description of the invention
For the technological means making this utility model realize, creation characteristic, reach purpose and be prone to bright with effect
White understanding, below in conjunction with being specifically illustrating, is expanded on further this utility model.
Embodiment 1
Seeing Fig. 2 and Fig. 3, be given in figure is slip-proof screwdriver, and including driver bit 100, it is one
Font structure.The front end face 110 of driver bit 100 is a plane.Driver bit 100 have a pair with
Axis 120 centrosymmetry of driver bit 100 is arranged and recessed to axis 120 direction of driver bit 100
Circular arc reverse slope 130a, the 130b fallen into, lower limb 131a, 131b of circular arc reverse slope 130a, 130b
It is connected on the periphery of front end face 110 of driver bit 100.
During use, the groove 211 on the head 210 of the front end alignment screw 200 of driver bit 100 is also
Embed in the groove 211 on the head 210 of screw 200, due to circular arc reverse slope 130a, 130b and spiral shell
Reverse gantry α and β is formed, in the mistake of turn driver bit 100 between the front end face 110 of silk cutter head 100
Without driver bit 100 being applied excessive power vertically downward in journey, the screw 200 that can will tighten
Screw out screw hole or by screw 200 DRIVE SCREWS hole, driver bit 200 also will not be along circular arc reverse slope
130a or 130b skids off the groove 211 on screw head 210.
Embodiment 2
Seeing Fig. 4 and Fig. 5, the driver bit 100 ' in the present embodiment is cross-shaped configuration, driver bit
The front end face 110 ' of 100 ' is a plane, and driver bit 100 ' has two to driver bit 100 '
Axis 120 ' centrosymmetry is arranged and anti-to the circular arc of the axis 120 ' direction of driver bit 100 ' depression
Inclined-plane 130a ', 130b ', 130c ', 130d ', circular arc reverse slope 130a ', 130b ', 130c ',
On the periphery of the front end face 110 ' that the lower limb of 130d ' is connected to driver bit 100 '.
Of the present utility model ultimate principle and principal character and of the present utility model excellent have more than been shown and described
Point.Skilled person will appreciate that of the industry, this utility model is not restricted to the described embodiments, above-mentioned
