The bottom end of the insertion rod 2 is conical, and the top end of the insertion rod 2 passes through the hexagonal screw head 10. Both sides of the insertion rod 2 are provided with a connecting rod 4 and a block 7. The two ends of the connecting rod 4 facing each other are integrally formed with a first protrusion 40, and the ends of the two connecting rods 4 facing each other are integrally formed with a second protrusion 5. Both sides of the anti-disassembly cover 3 are provided with slots for inserting the connecting rod 4 and the first protrusion 40. The top of the hexagonal screw head 10 is provided with two sliding grooves for sliding the block 7. The two side walls facing the block 7 are welded and fixed with a boss 8, and the two bosses 8 are sleeved with a spring 9. Two card slots adapted to the block 7 are provided in the anti-disassembly cover 3.
[0024] When in use, press the two second protrusions 5, the two first protrusions 40 squeeze the two card blocks 7, and the two card blocks 7 come out of the card slots in the anti-dismantling cover 3, making it easy to remove the anti-dismantling cover 3, pull out the insertion rod 2, screw the screw 1 into the screw hole on the fixed object and tighten the hexagonal screw head 10 with a wrench, after fixing the object, insert the insertion rod 2 into the inclined hole and press, squeeze the bottom end of the insertion rod 2 into the object, place the anti-dismantling cover 3 on the hexagonal screw head 10 and press, after the anti-dismantling cover 3 is in place, the two springs 9 push the two card blocks 7 to reset, and the two card blocks 7 are inserted into the anti-dismantling cover In the cover 3, the anti-dismantling cover 3 blocks the insertion rod 2 to prevent the insertion rod 2 from moving up, thereby preventing the screw 1 from loosening. After rotating the two second protrusions 5 ninety degrees, the connecting rod 4 can be pulled out. The user keeps the connecting rod 4 well. The anti-dismantling cover 3 covers and protects the hexagonal screw head 10 to prevent theft. If the screw 1 needs to be removed, the user inserts the two connecting rods 4 into the anti-dismantling cover 3 and rotates the two second protrusions 5 ninety degrees. The anti-dismantling cover 3 can be removed by pressing the two second protrusions 5, pulls out the insertion rod 2, and uses a wrench to disassemble the hexagonal screw head 10 and the screw 1.
