After the position is determined, the positioning push rod 708 can push the output end to directly lock onto the sliding block 705 to achieve a fixed effect. The sliding support rod 1 701 and the sliding support rod 2 702 are slidably connected by the sliding block 705 and the adjustment hole 706. The output end of the electric push rod 6 can drive the sliding tooth block 601 to lock onto the fixed rack 602 to fix the position of the movable intermediate plate 5.
