For example, the first limiting wheel 31 and the second limiting wheel 32 may be fixed on the slider 20 by corresponding limiting wheel shafts.

In some embodiments, the second stop assembly 40 includes four fixed wheels. Two fixed wheels are respectively arranged on the mounting plates 10 at two sides of the sliding piece 20.

Referring to fig. 3 to 5, the second limiting assembly 40 exemplarily includes four fixed wheels, namely a first fixed wheel 41a, a second fixed wheel 41b, a third fixed wheel 41c and a fourth fixed wheel 41d. The transmission belt 70 is sleeved on the first fixed pulley 41a, the first limit pulley 31, the second fixed pulley 41b, the driving pulley 50, the third fixed pulley 41c, the second limit pulley 32 and the fourth fixed pulley 41d.

Referring to fig. 4, for example, when the first driving member 60 rotates clockwise (e.g., the direction R1 in fig. 4), the driving wheel 50 rotates clockwise along with the first driving member 60, the lower portion of the transmission belt 70 moves to the left (e.g., the direction X1 in fig. 4) due to the pulling force of the driving wheel 50, and the rightmost first free end 71 and the second free end 72 of the transmission belt 70 are fixedly mounted on the mounting plate 10, so that the second limiting wheel 32 can only ascend to satisfy the requirement that the lower portion of the transmission belt 70 moves to the left, and at the same time, the upper portion of the transmission belt 70 becomes longer, and the second limiting wheel 32 moves upward to drive the sliding member 20 to move upward in the vertical direction, so that the workpiece disposed on the sliding member 20 moves upward from bottom to top in the vertical direction.

Referring to fig. 5, for example, when the first driving member 60 rotates in a counterclockwise direction (e.g., a direction R2 in fig. 5), the driving wheel 50 rotates counterclockwise along with the first driving member 60, the upper portion of the transmission belt 70 moves to the left (e.g., a direction X1 in fig. 5) due to the pulling force of the driving wheel 50, and the rightmost first free end 71 and the rightmost second free end 72 of the transmission belt 70 are fixedly mounted on the mounting plate 10, so that the first limiting wheel 31 can only descend to satisfy the requirement that the upper portion of the transmission belt 70 moves to the left, and meanwhile, the lower portion of the transmission belt 70 becomes longer, and the first limiting wheel 31 moves downward to drive the sliding member 20 to move downward in a vertical direction, so that the workpiece disposed on the sliding member 20 moves downward in the vertical direction.
