Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example 1

[0024] See also Figure 1-5 In the figure, a flower-shaped anti-theft bolt comprises an anti-theft bolt body 1, an end head 2 is fixedly arranged on the upper end surface of the anti-theft bolt body 1, an anti-theft cover 4 is arranged on the outer side of the end head 2, a mounting groove 6 is provided on the upper end surface of the anti-theft cover 4, a through groove 9 is provided on the upper end surface of the end head 2, a limiting plate 7 is provided inside the mounting groove 6, a mounting rod 8 is fixedly provided on the lower end surface of the limiting plate 7, the other end of the mounting rod 8 is arranged inside the through groove 9, a mounting groove 2 10 is provided on the left side of the mounting rod 8, and a mounting groove 2 10 is provided on the right side inside the mounting groove 2 A spring 11 is fixedly arranged, and an L-shaped clamping plate 12 is fixedly arranged at the other end of the spring 11. An L-shaped clamping groove 14 is opened on the left side of the through groove 9, and a mounting groove 3 15 is opened at the bottom inside the through groove 9. A mounting plate 16 is arranged inside the mounting groove 3 15, and a limiting rod 17 is fixedly arranged on the lower end surface of the mounting plate 16. A spring 2 18 is sleeved on the outer side of the limiting rod 17, and the upper end of the spring 2 18 is fixedly arranged on the lower end surface of the mounting plate 16, and the lower end of the spring 2 18 is fixedly arranged on the bottom inside the mounting groove 3 15.

[0025] See also Figure 5 A receiving groove 13 is provided on the left side of the limiting plate 7, and the L-shaped clamping plate 12 and the receiving groove 13 match each other.

[0026] In this embodiment, the opening of the receiving groove 13 facilitates the L-shaped clamping plate 12 to be received inside the receiving groove 13 , thereby facilitating the installation and removal of the limiting plate 7 and the mounting rod 8 .

[0027] See also Figure 5 A limiting groove 19 is provided at the bottom of the installation groove three 15 , and the other end of the limiting rod 17 is arranged inside the limiting groove 19 .

[0028] In this embodiment: the opening of the limit groove 19 facilitates the setting of the other end of the limit rod 17, so that the limit rod 17 can play a role in limiting and giving way. When the spring 18 is compressed, the limit rod 17 can cooperate with the spring 18 to move up and down inside the limit groove 19.

[0029] See also Figure 5 The left side of the lower end of the L-shaped card plate 12 and the bottom inside the L-shaped card slot 14 match each other.

[0030] In this embodiment: the left side of the lower end of the L-shaped card plate 12 and the bottom inside the L-shaped card slot 14 match each other. When the L-shaped card plate 12 moves downward, the L-shaped card plate 12 can be moved inward by the bottom of the L-shaped card slot 14, so that it can be stored in the storage slot 13.

[0031] See also Figure 1 A cross groove 20 is formed on the upper end surface of the limiting plate 7 .

[0032] In this embodiment, the cross groove 20 requires personnel to use corresponding tools to rotate the limit plate 7, thereby further improving the anti-theft capability.

[0033] Working principle: when the anti-theft bolt body 1 needs to be disassembled after being tightened and installed, the personnel first need to use a tool matched with the cross groove 20 to press the limit plate 7 downwards, so that the limit plate 7 can drive the installation rod 8 and the L-shaped card plate 12 to move downwards, and the L-shaped card plate 12 is moved inward by the bottom of the L-shaped card groove 14, so that the L-shaped card plate 12 can be stored in the storage groove 13, at this time, the spring 18 is compressed, and then the installation rod 8 is rotated, at this time, the L-shaped card plate 12 can be separated from the plane where the L-shaped card groove 14 is located, and the personnel can remove the L-shaped card plate 12 from the plane where the L-shaped card groove 14 is located. The staff releases the pressure on the limit plate 7, and the rebound force of the spring 18 can push the mounting rod 8 to move upward through the mounting plate 16, so that the limit plate 7 can extend from the inside of the mounting slot 1 6. The staff can then take out the mounting rod 8 from the inside of the through slot 9, and take out the anti-theft cover 4 from the end head 2, and then use a tool paired with the rotating slot 3 to rotate the anti-theft bolt body 1 to unscrew it; the disassembly of the anti-theft bolt body 1 requires the use of two paired tools, and the internal mechanism needs to be understood before disassembly, thereby improving the anti-theft performance.

[0034] Example 2

[0035] See also Figure 2-3 This embodiment further explains Example 1. In the figure, a rotation groove 3 is provided on the outer side of the end head 2, and a positioning protrusion 5 is fixedly provided inside the anti-theft cover 4. The rotation groove 3 and the positioning protrusion 5 match each other.

[0036] In this embodiment, the arrangement of the rotating groove 3 and the positioning protrusion 5 facilitates the anti-theft cover 4 to be sleeved on the anti-theft bolt body 1 , thereby playing an anti-theft role for the anti-theft bolt body 1 .

[0037] See also Figure 2-3 , six rotating grooves 3 and six positioning protrusions 5 are provided.

[0038] In this embodiment, six rotation slots 3 are provided, and personnel need to use matching tools to be able to rotate the anti-theft bolt body 1 down, thereby improving the anti-theft capability to a certain extent.
