The rotating sleeve 3 is provided with a through hole for passing the screw 603, and the screw 603 is threadedly penetrated by the lower thread of the clamping strip 5. There are two screws 603, and the rotation of the two screws 603 can drive the two clamping strips 5 to move toward or in the opposite direction. The clamping assembly 6 also includes a rotating rod 604, which penetrates and is rotatably connected to the front of the rotating sleeve 3. A shaft sleeve is provided between the rotating rod 604 and the rotating sleeve 3, and the shaft sleeve penetrates and is fixedly connected to the rotating sleeve 3.

The crown gear 606 is fixedly connected to the outer surface of the rotating column 602.

[0024] When the above-mentioned equipment is used, the pipe to be cut is first put on the outer surface of the two clamping strips 5 on the rotating sleeve 3, and then the rotating rod 604 is rotated. The rotation of the rotating rod 604 will drive the bevel gear 605 to rotate, and the rotation of the bevel gear 605 will drive the crown gear 606 to rotate. The rotation of the crown gear 606 will drive the rotating column 602 to rotate in the shaft bracket 601, and the rotation of the rotating column 602 will drive the screws 603 at its upper and lower ends to rotate.
