The clamping assembly includes a support leg 2, a base 3, a protective cover 4, a forward and reverse thread screw 5, a worm gear 6, a worm 7, a motor 8, a slider 9 and a clamping plate 10. The workbench 1 is provided with two groups of symmetrically arranged support legs 2, a base 3 is provided on the support leg 2, and the protective cover 4 is provided at one end of the base 3. Sliding holes are provided on the left and right sides of the base 3, and the forward and reverse thread screws 5 are provided in the sliding holes. One end of the rod 5 passes through the base 3 and the protective cover 4 and is connected to the center of the worm gear 6. The worm 7 and two groups of worm gears 6 are provided in the protective cover 4. The worm 7 is engaged with the worm gear 6. The output end of the motor 8 passes through the protective cover 4 and is connected to the worm gear 6. Two groups of symmetrically arranged splints 10 are provided on the base 3.
