The locking column 408 is fixed to the bottom end of the fixing column 407. The locking hole 403 is opened at the top end of the bottom plate 1. The locking column 408 is slidably connected to the inside of the locking hole 403.

[0027] The locking block slot 409 is provided on the inner wall of the locking hole 403, the locking block 410 is slidably connected to the inside of the locking block slot 409, and extends to the top of one end inside the locking hole 403 to lean against the inclined surface, and the first spring 411 is connected between the inner wall of the locking block slot 409 and the other end of the locking block 410;
