Preferably, a cuboid slot is arranged in the base, and the traction device is arranged in the slot. The traction device may include a lead screw and a nut disposed in a slot of the base. For example, the nut is rectangular in shape and mates with the shape of the slot so that the nut can move along the slot without rotating. The middle part of the screw rod is provided with threads which are connected with the nuts in a threaded manner. The screw rod is rotatably arranged on the base, and the screw rod can drive the nut to move along the slot by rotating, so that the supporting plate is driven to move, and the traction function is realized.

Preferably, screw bearings are arranged at two ends of the base slot, and two ends of the screw are fixedly arranged on the screw bearings in a penetrating mode. The screw may rotate within the slot but cannot move along the slot. One end of the screw rod extends out of one side of the base, and a rotating part is arranged at the end part. For example, a knob can be arranged, and the screw rod is driven to rotate by rotating the knob, so that the nut is driven to move along the slot, and the traction function is realized.

Preferably, a pivot connection is provided between the carrier and the nut, the carrier being rotatable relative to the nut. Further, the pivot connection has a locking mechanism. For example, the locking mechanism includes a spring pin and a plurality of pin holes. The connecting piece is provided with a plurality of pin holes, and when the spring pin is inserted into the pin holes, the pivot connecting piece between the supporting plate and the nut is locked and cannot rotate relatively. By inserting the spring pins into different pin holes, the angle between the pallet and the nut can be adjusted.
