[0076] The two positioning guide devices 4 are respectively arranged on the top of the hollow guide frame 301 and the top of the support frame 303 .

[0077] The design of the connecting rod 302 and the support frame 303 facilitates the installation of the positioning guide device 4 at the bottom of the hollow guide frame 301, and can utilize the connecting rod 302 to avoid the connecting rod 302 while maintaining connectivity.
