[0027] Preferably, a support leg 3 is fixedly provided under the operating table 2, and an anti-skid pad 31 is fixedly installed under the support leg 3. By providing the anti-skid pad 31, the anti-skid ability of the support leg 3 is increased, and the safety of the support leg 3 when in use is ensured. An extension buckle 41 is provided on the outer wall of the placement plate 4, and a fixing column 42 is installed in the extension buckle 41. The placement plate 4 is screwed to the operating table 2 through the fixing column 42, which increases the stability and safety of the placement plate 4 and is convenient for the user to disassemble and assemble the placement plate 4 later, providing convenience for the user. Elastic pads 56 are installed on the inner walls of the clamp 1 5 and the clamp 2 55, and the elastic pads 56 are fixedly connected to the clamp 1 5 and the clamp 2 55. By providing the elastic pad 56, the safety of the installation clamp is increased, and the clamp can avoid the situation where the workpiece is squeezed and worn during the clamping process.

[0028] Preferably, multiple groups of hexagonal bolts 52 are provided, and dust caps 53 are installed on the multiple groups of hexagonal bolts 52. The dust caps 53 are movably connected with the hexagonal bolts 52. By setting the dust caps 53, the hexagonal bolts 52 can be dust-proofed to avoid the problem of dust accumulation and clogging of the hexagonal bolts 52. A support frame 591 is installed outside the motor 59, and the support frame 591 is fixedly connected to the motor 59. The stability of the motor 59 is increased by setting the support frame 591, which ensures the safety of the motor 59 when in use.
