The special handling tool can directly screw in and out round head square-neck bolts.
Description
Technical field
The present invention relates to a kind of special handling tool of round head square neck bolt.
Background technology
Round head square neck bolt has another name called cup square neck bolt, and occupation mode is normally fixed in afterbody top nut, if but want the occupation mode of round head square neck bolt to change into direct screw-in and back-out as the screw, just must use special handling instrument.
Summary of the invention
Object of the present invention is exactly the special handling tool proposing a kind of round head square neck bolt, round head square neck bolt directly can be screwed in and screw out.
For achieving the above object, the special handling tool of a kind of round head square neck bolt of the present invention, comprise main body, clamping finger, bearing pin and screw, described main body is provided with the downward through slot in openend with vertical and run through the through screw of through slot bottom land, the both sides cell wall of described through slot is provided with axis hole, described clamping finger is provided with rotation axis hole, this rotation axis hole one end is provided with oblique angle, the other end is provided with folder and hooks, described bearing pin is also fixedly connected with it through the axis hole of main body through slot both sides cell wall, described clamping finger is provided with two, be located on the bearing pin in main body through slot by its rotation axis hole activity with being mutually symmetrical, breach between this two clampings finger oblique angle is V-shaped, just to the through screw of main body, the folder of this two clampings finger hooks toward each other, outside the openend being in main body through slot, described screw screws in the through screw of main body.
Hook end face the best that described folder hooks is a plane, to coordinate with the neck of round head square neck bolt.
Head the best of described screw is square, and afterbody the best is bullet-shaped in dumpling made of glutinous rice flour.
Outer wall the best of the through screw of described main body is provided with handle.
When screw screws in the through screw of main body, arrive at the v-notch between two clamping finger oblique angles, and screw, two clamping finger beveled end are softened under the effect of screw, and the folder of two clamping fingers hooks and closes up, then two clamping finger lockings, when unclamping screw, the beveled end of two clamping fingers just can inwardly be closed up, and the folder of two clamping fingers hooks separately, then two clamping fingers are opened.
The special handling tool of a kind of round head square neck bolt of the present invention, when two clamping fingers are opened, can be placed on the square neck of round head square neck bolt, then, screw in screw and screw, then two clamping finger lockings, now, namely rotate round head square neck bolt by special handling tool of the present invention, like this, just round head square neck bolt directly can be screwed in and screws out and use.
