[0024] A horizontal support plate 6 is installed on the lifting seat 5. A force sensor 7 is installed at the bottom of the horizontal support plate 6. An upper clamp is connected to the bottom of the force sensor 7.

[0025] The upper clamp includes a top plate 23 connected to a force sensor 7, and side plates 24 connected to both sides of the top plate 23, forming a U-shaped structure. Threaded holes are provided on both side plates 24, and tightening screws 25 are threaded into these holes. Side clamping plates 26 are slidably mounted between the two side plates 24.

[0029] The bottom of the vertical lead screw 3 is connected to the input shaft of the commutator 8. The output shaft of the commutator 8 is connected to the drive shaft 9. One end of the drive shaft 9 is equipped with a first gear 10. When the motor 4 drives the vertical lead screw 3 to rotate, the vertical lead screw 3 will synchronously drive the input shaft and output shaft of the commutator 8 to rotate.

[0034] During the clamping process of the lower clamp, we can first rotate the clamping screw 29 on the rear upright plate 28 of the clamping assembly, so that the inner plate 30 of the rear clamping screw 29 moves inward a certain distance. Then, the wooden board is placed between the front and rear upright plates 28 of the two clamping assemblies, and the clamping screw 29 on the front upright plate 28 of the two clamping assemblies is rotated, so that the inner plate 30 on the front clamping screw 29 clamps the wooden board.

[0036] The working process of this utility model is as follows: First, the wooden board is clamped on the sliding seat 14 with the edge banding of the wooden board facing upward. One end of the edge banding of the wooden board is inserted into the upper clamp and clamped by the upper clamp. Then, the motor 4 is started. The motor 4 causes the vertical lead screw 3 to rotate. The vertical lead screw 3 causes the lifting seat 5 to move upward at a fixed speed. At the same time, the vertical lead screw 3 causes the drive shaft 9 to rotate through the commutator 8. The first gear 10 on the drive shaft 9 causes the third gear 16 to rotate through the second gear 15. The third gear 16 causes the horizontal lead screw 13 to rotate. The horizontal lead screw 13 drives the sliding seat 14 to move laterally. The vertical lead screw 3 and the horizontal lead screw 13 rotate at the same speed, so that the sliding seat 14 and the lifting seat 5 move at the same speed.
