[0047] In some embodiments, Figure 3 As shown, a strip groove 231 a is processed on the threaded pin 231 , and the arrangement of the strip groove 231 a increases the disassembly method of the threaded pin 231 .

[0048] Furthermore, strip patterns are provided on the outer periphery of the threaded pin 231 to increase the friction between the pliers and the threaded pin 231 . The design of the strip groove 231 a facilitates the removal of the threaded pin 231 by a flat-blade screwdriver.

[0049] In some embodiments, Figure 3 As shown, the arc-shaped plate 22 is provided with first cutouts 221 , and the first cutouts 221 are evenly distributed along the arc-shaped plate 22 .
