Since the guide pulley 710 is mounted on the support frame 220 through the slider 720 and located below the panel 210, and the latch mounting mechanism, the block mounting mechanism and the chain belt conveying mechanism are respectively located above the panel 210, the tightness of the chain belt 101 can be adjusted between the first chain belt conveying mechanism 610 and the second chain belt guiding and positioning assembly 410 by the lifting and lowering of the guide pulley 710; but also fully utilize the space above and below the panel 210, making the structure of the device more compact and occupying less space.
