The two sides of the two groups of inner support sliders 302 facing each other are both wedge-shaped. The bottoms of the two groups of inner support sliders 302 are fixedly connected to connecting columns 303. The two groups of connecting columns 303 A tension spring 304 is arranged between the two groups of connecting columns 303, and the two ends of the tension spring 304 are respectively hooked with two groups of connecting columns 303. A top plate 305 is fixedly connected to the top of the mounting column 301, and an adjusting screw 306 is rotatably connected to the middle of the top plate 305. The adjusting screw 306 passes through the top plate 305, and a stopper 307 is abutted between the two groups of inner support sliders 302. A threaded hole that matches the adjusting screw 306 is opened at the position of the stopper 307 facing the adjusting screw 306.

[0034] Working principle: The cylindrical workpiece is sleeved on the outside of the inner support mechanism 300, and the adjusting screw 306 is rotated with a suitable hexagonal wrench. Since the two sides of the stop block 307 are stuck and cannot be rotated, the adjusting screw 306 will drive the stop block 307 to move upward or downward according to the rotation direction. When the stop block 307 moves, it will push the two groups of inner support sliders 302 to extend or retract into the sliding groove 301a. The adjusting screw 306 is rotated to make the two groups of inner support sliders 302 press against the inner side of the workpiece, and then the bidirectional screw 204 is rotated with a suitable hexagonal wrench. When the bidirectional screw 204 rotates, it will drive the two groups of threaded cylinders 203 to move closer or farther from each other according to the rotation direction, and then drive the two groups of clamping blocks 201 to move closer or farther from each other. The bidirectional screw 204 is rotated to make the two groups of clamping blocks 201 clamp the outer side of the workpiece to complete the workpiece fixation. After the subsequent workpiece processing is completed, the bidirectional screw 204 and the adjusting screw 306 are rotated in reverse order to remove the workpiece.
