Fig. 3 is the utility model bolt front view.
In figure: 1 bolt head, 2 plectanes, 3 protection shells, 4 elastomeric pads, 5 screw rods, 6 stripper plates, 7 springs, 8 tightens mouths, 9
Unidirectional tooth, 10 elastic extruding plates.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1-3, the utility model provides a kind of technical solution: it is a kind of can loosing-proof rust-proof anti-theft bolt, including
Shell 3 is protected, the bottom of the protection shell 3 is fixed with elastic extruding plate 10, and the inner cavity of the protection shell 3 is equipped with bolt
First 1, the bottom of the bolt head 1 is fixed with plectane 2, and the lower section of the plectane 2 is equipped with stripper plate 6, the plectane 2 and extruding
Spring 7 is fixed between plate 6, the top of the top of the spring 7 and low side respectively with 2 bottom of plectane and stripper plate 6 is fixed
Connection, the bottom of the stripper plate 6 are fixed with elastomeric pad 4, the lower section screw rod 5 of the elastomeric pad 4, the screw rod 5
