Two synchronous belts are tensioned and connected to the main synchronous shaft and the secondary synchronous shaft. The two synchronous belts are connected to the two ends of the sliding frame 21 to achieve synchronous drive.

[0062] The synchronous belt assembly 23 of one of the beam devices 20 is a first belt group 231, and the synchronous belt assembly 23 of the other beam device 20 is a second belt group 232.
