[0017] 1. The utility model places the steel bar between the clamping blocks by setting components such as sliding block 1, two-way bolts, sliding block 2, and screw rod 1. Because the sliding block 1 and screw rod 1 are slidably connected, rotating the two-way bolt drives the two sliding blocks 1 to move relatively, and the steel bar is clamped by the relative movement between the clamping blocks.

The rotation of bevel gear 4 drives screw 2 to rotate. The threaded block is driven to rise and fall through the threaded connection between screw 2 and the threaded block. The limiting effect of the threaded block is achieved through the limiting cylinder. The wheel group is used to drive the entire device to move.
