Drive assemblies, namely a first motor 2 and a second motor 3, are provided on one side of both the first sprocket 21 and the second sprocket 31. The output end of the first motor 2 is connected to the first sprocket 21, and the output end of the second motor 3 is connected to the second sprocket 31. Two sets of encoders 9 are fixed inside the second fixing plate 12, and the two sets of encoders 9 are respectively connected to the shafts of the first sprocket 21 and the second sprocket 31. A guide 8 is installed at the end of the upper cable chain 5, and a deflection assembly 6 is sleeved on the outer wall of the upper cable chain 5. The deflection assembly 6 includes a sliding plate sleeved on the outer wall of the upper cable chain 5. 61, and the bottom of the slide plate 61 is provided with a sliding groove 610. When the upper drag chain 5 slides, the slide plate 61 slides above the lower drag chain 4. The sliding groove 610 makes the slide plate 61 slide above the lower drag chain 4, which can prevent the slide plate 61 from separating from the lower drag chain 4. The end of the slide plate 61 is movably installed with a movable plate 611. The end of the lower drag chain 4 is installed with a positioning plate 7, and the top of the positioning plate 7 is fixed with a limit post 71. The end of the limit post 71 is provided with a slot 72. The top of the slide plate 61 is movably installed with a connecting block 63. The top of the slide plate 61 is movably installed with a guide sleeve 62, and the outer wall of the guide sleeve 62 is movably connected to the end of the connecting block 63.

The top of the slide plate 61 is fixed with a fixing plate 68, and the other side of the top of the slide plate 61 is movably installed with a connecting rod 612.

[0028] Please see Figure 4 and Figure 6 A triangular block 81 is fixed on one side of the guide member 8, and a locking position 82 is provided on one side of the outer wall of the guide member 8. The triangular block 81 can limit the guide member 8, preventing the guide member 8 from completely entering the interior of the guide sleeve 62 when it is reset. Under the action of the triangular block 81, the end of the guide member 8 is located outside the guide sleeve 62. The locking position 82 can cooperate with the contact rod, and when the guide member 8 pushes the contact rod 66 through the locking position 82, it causes the upper drag chain 5 to change the direction of its extension movement.

[0029] Please see Figure 5 and Figure 6Both ends of the guide rod 64 are provided with pulleys 65, which can reduce the friction between the guide rod 64 and the triangular block 81 and the fixed plate 68. When the triangular block 81 touches the pulley at one end of the guide rod 64, the pulley at the other end of the guide rod 64 is separated from the top end of the fixed plate 68 and slides along the outer wall of the fixed plate 68, so that the deflection assembly 6 is reset.
