Detailed Description

The utility model is further described below with reference to the following figures and specific examples.

An anti-theft bolt and a disassembling tool thereof comprise: the anti-theft nut comprises an anti-theft nut 1, wherein the lower part of the anti-theft nut 1 is a threaded column 2, the upper part of the anti-theft nut 1 is a bolt head 3, a groove 4 is formed in the bolt head 3, the groove 4 is communicated with a square groove 6 through a circular groove 5, and the outer side of the bolt head 3 is circular; assembly and disassembly tools 15, assembly and disassembly tools 15's action bars 7 and dwang 8 are connected through first hinge 9, action bars 7 and dwang 8 operating condition ninety degree contained angle, the state of packing up is laminated each other, the tip of action bars 7 is the mirror image respectively and sets up two second hinges 11, second hinge 11 connects and twists

reverse piece

10, 13 fixed settings of supporting shoe of second hinge 11 are on twisting reverse piece 10, the both sides of supporting shoe 13 are laminated respectively and are set up two and press from both sides tight piece 12, press from both sides tight piece 12 and supporting shoe 13 and connect through pivot 14, supporting shoe 13 is round 14 relative tight piece 12 rotations that press from both sides of pivot.

The central axis of the threaded stud 2 coincides with the central axis of the bolt head 3. The bolt head 3 is a cylinder. The diameter of the circular groove 5 is equal to the width of the square groove 6. The length of the swivelling levers 8 is smaller than the length of the operating lever 7. The width of the clamping block 12 and the two support blocks 13 is equal to the width of the torsion block 10. The length of the shaft 14 is equal to or less than the width of the twist block 10.

During the use, with 15 operating lever 7 of assembly and disassembly tools and dwang 8 by the laminating state rotation, make operating lever 7 rotate round the relative dwang 8 of first hinge 9, make operating lever 7 and dwang 8 mutually perpendicular, make things convenient for follow-up the torsion. The twisting block 10 of the operating rod 7 is deeply inserted into the groove 4 and firstly enters the circular groove 5, the clamping block 12 and the supporting block 13 rotate around the rotating shaft 14 in the square groove 6, the clamping block 12 is fixed, the supporting block 13 drives the twisting block 10 to rotate, the twisting block 10 is placed in the square groove 6, and the two twisting blocks 10 respectively extend into two sides of the square groove 6.
