After moving to the expected position, the extension plate 301 is rotated back to realize its template function.

[0029] The length of the first fixing block 304 is greater than that of the second fixing block 305 , so that the first hydraulic cylinder 303 can normally drive the extension plate 301 to rotate when extending and retracting, and will not get stuck.
