When the pipe is fixed, first, the pipe is placed on the support seat, and the support seat supports the bottom of the pipe. Then, the first driving member is actuated to push the first clamping plate to abut against the pipe, and the second driving member is actuated at the same time to push the second clamping plate to abut against the pipe, thereby performing a three-point abutment fixed limit on the pipe. Then, the trimming worker can perform cutting and trimming work, thereby realizing rapid and stable fixation of the pipe when cutting and trimming the HDPE hollow wall winding pipe, which is conducive to reducing manual workload, facilitating cutting and trimming of the pipe after rapid fixation, and is more convenient to use.

[0029] like Figure 4As shown, a PVC pipe cutting and fixing component, the height adjustment component 4 includes a first lifting leg 401, the side of the first lifting leg 401 is rotatably connected to a rotating handle 402, and the end of the rotating handle 402 is fixedly connected to a transmission worm 403, and the other end of the transmission worm 403 is fixedly connected to a support shaft 404, the side of the transmission worm 403 is meshed with a transmission worm gear 405, and the top of the transmission worm gear 405 is fixedly connected to a lifting screw 406, the external thread of the lifting screw 406 is connected to a lifting nut 407, and the outside of the lifting nut 407 is fixedly connected to a second lifting leg 408, the top of the lifting screw 406 is rotatably connected to a supporting top block 409, and the back of the supporting top block 409 is fixedly connected to a T-shaped The slider 410, the transmission worm 403 forms a transmission structure through the transmission worm wheel 405 and the lifting screw 406, and the lifting screw 406 and the support top block 409 form a rotating structure, and the support top block 409 forms a sliding structure with the second lifting leg 408 through the T-shaped slider 410, the second lifting leg 408 forms a lifting structure with the lifting screw 406 through the lifting nut 407, and the second lifting leg 408 and the first lifting leg 401 form a sliding structure.

[0030] Working principle: First, the height of the fixed component can be adjusted according to the height or operating habits of the cutting worker. The rotating handle 402 is turned, and the rotating handle 402 rotates the transmission worm 403. At the same time, because the transmission worm 403 and the transmission worm wheel 405 are meshed with each other, the lifting screw 406 can be rotated together through the transmission worm wheel 405. Since the lifting screw 406 and the lifting nut 407 are threadedly connected, when the lifting screw 406 is rotated, the lifting nut 407 will move up and down on the rotating lifting screw 406, and then move up and down with the second lifting leg 408, so that the height of the top fixed component can be adjusted;

[0031] Then, the PVC pipe that needs to be cut is passed through the middle position of each pipe clamping block and adjusted so that the position where it needs to be cut is facing the cutting blade. Then, the fastening nut 205 is turned. The inner diameter of the fastening nut 205 is fixed. Since the thickness of the two ends of each pipe clamping block is different, when the fastening nut 205 is gradually screwed toward the thicker end of the pipe clamping block, the distance between the clamping blocks will gradually decrease, and then they will interact with each other to gradually clamp the PVC pipe from four directions. When both sides are clamped, the PVC pipe can be cut. After the cutting is completed, the fastening nut 205 is turned toward the thinner end of the clamping block. At this time, under the pulling action of each spring 302, the distance between the clamping blocks will increase again, and then the pipe can be taken out from between the clamping blocks.

[0032] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention, and such changes and improvements fall within the scope of the present invention as claimed.
