A fixing seat 5 is provided on the surface of the housing 1, and a screw 1 is provided inside the fixing seat 5. 4. A movable seat 8 is provided on the surface of the screw 14, and a rotating roller is provided on the inner side of the movable seat 8. The rotating roller 12 is rotatably connected to the movable seat 8. A mounting bracket 9 is provided on the surface of the fixed seat 5, and a drive shaft 15 is provided inside the mounting bracket 9. One end of the drive shaft 15 extends to the outside of the mounting bracket 9 and a drive motor 16 is mounted thereon. The power output end of the drive motor 16 is connected to the drive shaft 15, and the drive motor 16 is fixedly connected to the mounting bracket 9. A cutter 11 is fixedly mounted on the surface of the drive shaft 15. A sliding groove 6 is provided inside the housing 1, and a sliding block 17 is provided inside the sliding groove 6. An insertion block is provided on the upper part of the sliding block 17. 18. The upper part of the plug-in block 18 is provided with a placement seat 7. The placement seat 7 is slidably connected to the sliding groove 6 through the sliding block 17. The device is small and easy to carry. When laying the wire trough, the PPR pipe to be cut is placed on the placement seat 7. By rotating the screw 14, the movable seat 8 is fixed in the fixed seat 5. The PPR pipe is slid together with the placement seat 7 to the cutter 11. The drive motor 16 is started to drive the drive shaft 15 to rotate, so that the cutter 11 rotates at high speed to cut the PPR pipe. During the cutting process, the PPR pipe can be manually rotated to make the rotating roller drive the PPR pipe to rotate, so as to achieve circumferential cutting. The cut is smooth and the cutting efficiency is increased.
[0016] Further improvements, such as Figure 1 As shown: The side of the lid 2 is provided with a buckle 3 and the side of the body 1 is provided with a slot 4. The buckle 3 and the slot 4 are interlocked, and the lid 2 and the body 1 are tightly closed to prevent the lid 2 from being accidentally opened during carrying and to protect the internal parts of the cutting device from damage.
[0017] Further improvements, such as Figure 2 As shown: The surface of the box cover 2 is provided with a handle 13 that is fixedly installed. The design of the handle 13 makes it easier for users to carry and move the cutting device, thus improving the portability of the device.
[0018] Further improvements, such as Figure 4 As shown: The placement seat 7 is provided with a plug-in groove 19 inside and the plug-in block 18 is connected to the plug-in groove 19. The top of the inner side of the plug-in groove 19 is provided with a fixedly installed spring post 20 and the spring post 20 is in contact with the plug-in hole. This setting can adjust the height of the placement seat 7 so that it is flush with the cutting device.
[0019] Further improvements, such as Figure 2 As shown: The rotating rollers are arranged in two sets and are symmetrically arranged. The symmetrical arrangement of the rotating rollers can support and rotate the PPR pipe more evenly, ensuring that the PPR pipe remains stable during the cutting process.
[0020] Further improvements, such as Figure 3 As shown: One end of the screw 14 extends to the outside of the fixed base 5 and is equipped with an adjustment knob 10. The design of the adjustment knob 10 allows the user to easily adjust the position of the movable base 8 in the fixed base 5, thereby adapting to PPR pipes of different diameters and improving the versatility and flexibility of the device.
[0021] Working principle: Open the cover 2, place the PPR pipe to be cut on the placement seat 7, and adjust the position of the movable seat 8 according to the diameter of the PPR pipe by adjusting the knob 10 to make the rotating roller fit tightly against the PPR pipe. By adjusting the position of the movable seat 8, the tight contact between the rotating roller and the PPR pipe is ensured, providing stable support for subsequent cutting and rotation, improving the cutting accuracy and stability, and adapting to PPR pipes of different diameters, enhancing the versatility of the device. Then, slide the PPR pipe to the cutter 11 by sliding the placement seat 7. The locking design of the cover 2 and the sliding design of the placement seat 7 ensure the safety and stability of the cutting process, preventing possible accidents during the cutting process, improving user safety, and making the cutting process smoother. Start the drive motor 16, and the drive shaft 15 drives the cutter 11 to rotate at high speed to cut the PPR pipe. During the cutting process, the PPR tube can be manually rotated to make the rotating roller drive the PPR tube to rotate, thus achieving circumferential cutting. The cooperation between the drive motor 16 and the cutter 11 achieves efficient and flat cutting, while the design of the rotating roller makes circumferential cutting possible, improving cutting efficiency and quality, and making the cut surface smoother, thus meeting different cutting needs.
