[0023] The disassembly structure 3 includes a limit block 301, an electric telescopic rod 302, a spring 303, a connecting plate 304, a functional block 305, an insertion rod 306 and a limit cover 307. The limit block 301 is fixedly installed on the top of the support rod 207, the electric telescopic rod 302 is fixedly installed inside the support rod 207, the spring 303 is fixedly installed inside the limit block 301, the connecting plate 304 is fixedly installed outside the spring 303, the functional block 305 is fixedly installed outside the connecting plate 304, the insertion rod 306 is fixedly installed on the top of the support rod 207, and the limit cover 307 is sleeved on the outside of the limit block 301.
[0024] exist Figure 2 In the figure, the connecting rod 203 fixes the positions of the worm wheel 204 and the gear 205, and the bidirectional worm 202 and the toothed plate 206 are linked by the connecting rod 203, so that the two clamp bodies 4 can be driven to move at the same time.
[0025] exist Figure 3 In the embodiment, the bottom of the limiting cover 307 is fitted with the top of the support rod 207 , and the limiting cover 307 is connected to the support rod 207 through the limiting block 301 to limit the position of the clamp body 4 .
[0026] exist Figure 3In the figure, the expansion and contraction of the spring 303 can drive the functional block 305 to move through the connecting plate 304, and the electric telescopic rod 302 rises to form an ejecting force on the two functional blocks 305, so that the functional block 305 can be clamped to the limit cover 307.
