[0020] like Figures 1 to 5 As shown, a second drive motor 16 is fixedly mounted on the side of the worktable 1. A second lead screw 17 is fixedly mounted on the output end of the second drive motor 16, and the second lead screw 17 is rotatably connected to a slide groove opened on the top of the worktable 1. A moving block 18 is connected to the second lead screw 17 through a lead screw nut pair. A connecting plate 19 is fixedly mounted on the top of the moving block 18. The second drive motor 16 is fixedly mounted on the side of the worktable 1 by bolts, so that the second lead screw 17 is fixedly mounted on the output end of the second drive motor 16, and the second lead screw 19 is connected to the second lead screw 17 through a lead screw nut pair. The movable block 18 of the nut pair is slidably connected in the groove. The surface of the second lead screw 17 is provided with two movable blocks 18, and the internal threads of the two movable blocks 18 are opposite, so that when the second lead screw 17 rotates, it can drive the two movable blocks 18 to move in opposite directions. A connecting plate 19 is fixedly installed on the top of each of the two movable blocks 18, and a rotating ring 20 is rotatably connected inside each of the two connecting plates 19. A rotating device 21 is installed on the opposite side of each of the two rotating rings 20, and a clamping device 22 is installed on the side of one of the connecting plates 19.

[0021] like Figure 4As shown, the rotating device 21 includes a fixed disk 210, which is fixedly installed on the side of the rotating ring 20. A mounting bracket 211 is fixedly installed on the side of the connecting plate 19. A third drive motor 212 is fixedly installed on the side of the mounting bracket 211. A rotating column 213 is fixedly installed at the output end of the third drive motor 212. The other end of the rotating column 213 is fixedly installed on the side of the fixed disk 210. The mounting bracket 211 is fixedly installed on the side of the connecting plate 19 so that the third drive motor 212 is fixedly installed on the side of the mounting bracket 211 by bolts. The rotating column 213 is fixedly installed at the output end of the third drive motor 212, and the fixed disk 210 is fixedly installed at the other end of the rotating column 213. The fixed disk 210 is fixedly installed on the side of the rotating ring 20, which facilitates the rotation of the rotating ring 20 by the third drive motor 212, so as to facilitate the cutting of PVC pipes.

[0022] like Figure 5 As shown, the clamping device 22 includes a fixed ring 220, with a fixing bolt 221 threaded onto the surface of the fixed ring 220. A V-shaped clamping block 222 is fixedly installed at the other end of the fixing bolt 221. A limiting block 223 is fixedly installed at the bottom of the V-shaped clamping block 222, and the limiting block 223 is slidably connected in a groove opened on the surface of the fixed ring 220. A rubber pad is provided inside the limiting block 223. The fixed ring 220 is fixedly installed on the side of the rotating ring 20, and the fixing bolt 221 is bolted onto the surface of the fixed ring 220. The fixing bolt 221 passes through the interior of the fixing ring 220, and a V-shaped clamp 222 is fixedly installed at the other end of the fixing bolt 221 so that the PVC pipe can be clamped by the V-shaped clamp 222. Since there are two fixing bolts 221, it is necessary to use a tool to rotate the two fixing bolts 221. The rotated fixing bolt 221 limits the V-shaped clamp 222 through the limiting block 223, thereby facilitating the clamping of the PVC pipe by the two V-shaped clamps 222 and preventing the PVC pipe from moving.

[0023] Working Principle: During operation, when cutting PVC pipes, the cutting area needs to be preheated at a low temperature. This allows the first drive motor 2 to drive the first lead screw 3, which in turn moves the slider 4. The moving slider 4 moves the fixed ring 5 to the desired cutting position, where infrared lamps 6 heat the PVC pipe surface at a low temperature, softening it and reducing cutting dust. After the PVC pipe is preheated, the first drive motor 2 drives the first lead screw 3 to move the slider 4, facilitating the operation of the cylinder 9. The output of the cylinder 9 can raise and lower the protective cover 10. The cutting device body 11, fixedly installed on the side of the protective cover 10, facilitates the cutting of the PVC pipe. During cutting, a fan 12 absorbs the debris generated. A connecting pipe 13 is fixedly installed at the air inlet of the fan 12, and a collection tank 14 is fixedly installed at the other end of the connecting pipe 13 to collect the debris. Inside the tank 14, for convenient subsequent processing, a connecting hose 15 is fixedly installed on the other side of the collection tank 14, and the other end of the connecting hose 15 is installed on the top of the protective cover 10. Thus, the negative pressure generated by the fan 12 during use can absorb the debris generated during cutting. During the cutting process, the PVC pipe needs to be rotated to facilitate cutting. When rotating the PVC pipe, it needs to be fixed first. Then, a tool is used to rotate the two fixing bolts 221. The rotating fixing bolts 221 can drive the V-shaped clamp 222 to move through the limit block 223. The moving V-shaped clamp 222 can clamp the PVC pipe. After the PVC pipe is fixed, the third drive motor 212 can be started, so that the output end of the third drive motor 212 can drive the fixed plate 210 fixedly installed on the other end of the rotating column 213 to rotate. The rotating fixed plate 210 can drive the rotating ring 20 to rotate, thus facilitating the rotation and cutting of the PVC pipe.
