Positioning strip, positioning strip madial wall bottom end are equipped with positioning and protrude;The bottom of the groove opens up circular through hole, and through-hole, which is internally provided with, to be hit
Needle.
As improvement:The number of the positioning strip and positioning protrusion is two, and positioning strip is symmetricly set on lead two
Side.
As being further improved:The inside grooves are equipped with faceplate, and faceplate is equipped with screens, the position of screens and size with
The position of positioning protrusion and size match.
As being further improved:Spring B is arranged on the outside of the faceplate, the bottom of spring B is fixedly mounted on groove
Bottom.
As being further improved:The side wall of the striker is equipped with wing plate, and spring A, the top of striker are symmetrically installed on wing plate
Grafting is mounted on the inside of the pilot hole on lead.
As being further improved:The outside of the shank of screw is equipped with screw thread.
Compared with prior art, the advantage of the invention is that:The locating convex block of the present invention is usually at locating slot, screw
Head will not make pop-up, and four springs are in the oppression state, although heading on spring, but not pop up;When striker touching wall by
After compressing, spring B can further be compressed in striker and also not emancipated needle pellet bottom, when the side wing of striker will position
Convex block ejects, and four spring moments eject head of screw, realize anti-derotation;So as to avoid structural breakdown caused by screw derotation
The problem of causing serious adverse consequences.
