[0026] As an implementation method in this embodiment, Figure 5 As shown, the clamping mechanism 7 includes a guide cylinder 71 fixedly connected to the bottom of the fixed plate 310, a squeezing spring 72 is fixedly connected to the top of the inner cavity of the guide cylinder 71, a fixing column 75 is fixedly connected to the bottom end of the squeezing spring 72, and the bottom end of the fixing column 75 is fixedly connected to the top of the top clamping block 12, and sliding grooves 73 are symmetrically provided on both sides of the inner cavity of the guide cylinder 71, and a slider 74 is slidably connected to the inner wall of the sliding groove 73, and the side of the slider 74 away from the sliding groove 73 is fixedly connected to the top of the outer wall of the fixing column 75, and the slider 74 and the sliding groove 73 form a sliding connection structure.

After being fixed, the limit plug 13 is inserted into the socket 14 to complete the limit fixation of the turning handle 32 to prevent it from rotating. Conversely, the turning handle 32 only needs to be rotated counterclockwise to quickly complete the disassembly.

[0029] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
