Description
Technical field
The utility model 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 the afterbody top nut, but if want the occupation mode of round head square neck bolt is changed into as direct screw-in of screw and back-out, just must use special-purpose handling instrument.
Summary of the invention
The purpose of the utility model is exactly the special handling tool that proposes a kind of round head square neck bolt, can round head square neck bolt directly screwed in and screw out.
For realizing above-mentioned purpose, the special handling tool of a kind of round head square neck bolt of the utility model comprises main body, clamps finger, bearing pin and screw; Said main body is provided with the downward through slot of openend with vertical and run through the perforation screw of through slot bottom land, and the both sides cell wall of said through slot is provided with axis hole, and said clamping finger is provided with to rotate uses axis hole; This rotation is provided with the oblique angle with axis hole one end; The other end is provided with folder and colludes, and said bearing pin passes the axis hole of main body through slot both sides cell wall and is fixedly connected with it, and said clamping finger is provided with two; Be located on the bearing pin in the main body through slot with the axis hole activity through its rotation with being mutually symmetrical; Breach between this two clampings finger oblique angle is V-shaped, and over against the perforation screw of main body, the folder of this two clampings finger colludes against each other; Be in outside the openend of main body through slot, said screw threads is gone into the perforation screw of main body.
The end face the best of colluding that said folder colludes is a plane, so that and the neck of round head square neck bolt cooperation.
Head the best of said screw is square, and it is bullet-shaped that afterbody the best is dumpling made of glutinous rice flour.
Outer wall the best that said main body connects screw is provided with handle.
Go into the perforation screw of main body when screw threads, arrive at two v-notch that clamp between the finger oblique angles, and screw; Two clamp the finger beveled end is strutted under the effect of screw, and the folder of two clamping fingers colludes and closes up, and then two clamps finger locking; When unclamping screw; The beveled end of two clamping fingers just can inwardly be closed up, and two clamp the folder of pointing colludes separately, and then two clamping fingers are opened.
The special handling tool of a kind of round head square neck bolt of the utility model 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; At this moment; Can like this, just can direct screw-in of round head square neck bolt and back-out have been used through the utility model special handling tool rotation round head square neck bolt.
