Embodiment
It is described further referring to figs. 1 to Fig. 4 wear-resisting screw embodiments a kind of to the utility model.
A kind of wear-resisting screw, including screw head 1 and shank of screw 3, the screw head 1 include the first installed part 10 and the
Two installed parts 11, one end of second installed part 11 is fixedly connected with shank of screw 3, on the other end of second installed part 11
Provided with the mounting groove 12 being adapted with the first installed part 10, the bottom of the mounting groove 12 is recessed provided with second be embedded for screwdriver
Groove 13, one end that first installed part 10 is mounted opposite groove 12 is provided with the fixture 14 being adapted with the second groove 13, institute
The centre of fixture 14 is stated provided with cavity 15 and fixture block 16 is provided with both sides, the cell wall of second groove 13 is provided with and fixture block
Blocked by fixture block 16 is relative on 16 necks 17 being adapted, the inclined-plane that the fixture block 16 is provided with lozenges 18, the lozenges 18
One end of groove 17 is inclined upwardly setting, the opposed fixed member of the first installed part 10 to fixture block 16 and one end that fixture 14 is connected
14 other end is provided with the first groove 19.
The first installed part 10 and the second installed part 11 are provided with screw head 1, during assembling, first by screwdriver
The first groove 19 being inserted on the first installed part 10 carries out screwing assembling to screw, during assembling, if first
Groove 19 is damaged, and the first installed part 10 can be disassembled from screw, screw is assembled with the second installed part 11,
