[0025] The middle buckle 220 is fixed on the surface of the middle rail 200 , and the middle buckle 220 is fastened and connected to the synchronous belt B470 by the middle buckle 220 .

[0026] An upper buckle 110 is fixed on the surface of the upper rail 100 , and the upper clamping groove 120 fastens the synchronous belt A250 to the upper buckle 110 .

[0027] The lower buckle 310 is fixed on the surface of the lower rail 300 , and the lower buckle 310 is fastened to the synchronous belt A250 by the lower buckle 310 .

[0028] The driving mechanism includes a motor 410 and a gear box 420 mounted on the lower rail bracket 400 . The output end of the motor 410 is connected to the input end of the gear box 420 . The output end of the gear box 420 is connected to the driving wheel 440 . The motor 410 is a clutch motor.

[0029] A first retaining frame 700 is arranged between the middle rail 200 and the upper rail 100, and the first retaining frame 700 is connected to the middle rail 200. A second retaining frame 800 is arranged between the middle rail 200 and the lower rail 300, and the second retaining frame 800 is connected to the middle rail 200.
