It is not easy to disassemble, has good anti-theft performance, is easy to install and disassemble by oneself, and is convenient to use.

[0007] Furthermore, the triangular protrusion and the circular protrusion are arranged opposite each other on the lower end surface of the twist block. The irregular structure makes it inconvenient to find similar components to engage, and it is not easy to disassemble, thus improving the anti-theft performance.

[0008] Furthermore, the twist block is made of magnetic material, and it can be attracted and fixed when it is fastened to the surface of the round base.

[0009] Furthermore, the outer end surface of the conical ring block is provided with anti-slip grooves, which increases the anti-slip performance and ensures tight installation during use.

[0010] Furthermore, the hexagonal groove adopts a standard long gauge size, which facilitates the engagement and disassembly of the hex wrench, making it convenient for self-assembly and disassembly.

[0011] Compared with existing technologies, the advantages of this utility model are:

[0012] (1) It adopts rare component interlocking torsion round seat rotation installation. During installation, it needs to be installed and disassembled with the torsion block assembly of the fixed structure. After installation, the torsion block is removed. It is not easy to disassemble, has good anti-theft performance, is easy to disassemble and install by oneself, and is convenient to use.

[0013] (2) The triangular protrusion and the circular protrusion are set opposite each other on the lower surface of the twist block. The structure is irregular, making it inconvenient to find the same type of component to engage, and it is not easy to disassemble, thus improving the anti-theft performance.

[0014] (3) The twist block is made of magnetic material and can be attracted and fixed when it is fastened to the surface of the round base.

[0015] (4) The outer end surface of the conical ring block is provided with anti-slip grooves to increase anti-slip performance and ensure tight installation.

[0016] (5) The hexagonal groove adopts the standard size of the long gauge, which makes it easy to install and remove the internal hex wrench, and is convenient to use when disassembling and assembling by yourself. Attached Figure Description
