[0031] Specifically, the pipe to be cut is inserted into the positioning cover 6 and the base 1, and then the electric telescopic rod 3 is started. The first motor 4 is fixed to the positioning cover 6 and the gear 7 is engaged with the tooth groove 8 to push the positioning cover 6 up and down to adjust the pipe cutting depth. At the same time, the threaded rod 10 is rotated to drive the moving block 11 to move, and the spring telescopic rod 14 on the moving block 11 pushes the fixed plate 15 to fix the pipe. The spring telescopic rod 14 is used to make the cutting saw 13 contact with the pipe. Then, the second motor 12 is started to drive the cutting saw 13 to rotate for cutting. At the same time, the first motor 4 is started to drive the gear 7 to rotate, so that it drives the positioning cover 6 and the cutting saw 13 to rotate through the meshing transmission with the tooth groove 8. The fixed plate 15 only provides positioning for the pipe but does not clamp the pipe, so it will not rotate at the same time as the pipe. In addition, a rotating wheel can be installed on the adjacent side of the two fixed plates 15 to further fix the pipe without affecting the cutting, so as to achieve uniform cutting of the pipe and keep the cutting surface flat.

[0032] Reference Figure 3 The dust removal mechanism 2 includes a pressure spring 207, which is fixedly connected to the bottom of the inner wall of the base 1, and the top of the pressure spring 207 is fixedly connected to the impurity box 203.

[0033] Specifically, the residues produced by cutting are received by the impurity box 203, and at the same time, the air pump 208 is started to suck air through the hose 209, aiming to absorb the residues and prevent dust during cutting. When the residues continue to accumulate and the weight of the impurity box 203 gradually increases, the pressure spring 207 will be squeezed, which causes the indicator rod 204 to move along the reserved groove 205 and indicate to the corresponding indicator groove 206. By observing the indicator groove 206, the current amount of residue accumulation can be understood and cleaned in time to prevent excessive residue from affecting the normal operation of the device.

[0035] Specifically, the filter 202 can prevent impurities from entering the air pump 208 through the hose 209. Rotating the connecting ring 5 can simultaneously drive the scraper 201 to rotate to scratch the surface of the filter 202 to reduce the possibility of impurities clogging the filter 202. The handle 20 can facilitate holding and moving the device. The sheath 21 can improve the comfort of holding the device. By installing a threaded part in the positioning hole 23 on the positioning block 22, the device can be easily installed and fixed.

[0036] Reference Figure 1 , Figure 2 and Figure 3 A movable door 19 is provided on the top of the positioning cover 6, and a hinge 18 is fixedly connected to the front side of the movable door 19, and the movable door 19 is rotatably connected to the positioning cover 6 through the hinge 18; a knob 17 is rotatably connected to the outer side of the hollow rod 9, and the outer side of the knob 17 penetrates the hollow rod 9 and is fixedly connected to the threaded rod 10; a bracket 16 is fixedly connected to the bottom of the hollow rod 9, and the outer side of the bracket 16 is fixedly connected to the positioning cover 6;

[0037] Specifically, the movable door 19 can be opened and closed by the hinge 18 so that external dust can enter the interior of the device when the device is not in use. The threaded rod 10 can be easily rotated by the knob 17, and the stability of the fixation between the hollow rod 9 and the positioning cover 6 can be improved by the bracket 16.

[0038] Working principle: before using the device, first insert the pipe to be cut into the positioning cover 6 and the base 1, then start the electric telescopic rod 3, and push the positioning cover 6 up and down through the fixation of the first motor 4 and the positioning cover 6 and the engagement of the gear 7 and the tooth groove 8 to adjust the pipe cutting depth, and at the same time rotate the threaded rod 10 to drive the moving block 11 to move, and the spring telescopic rod 14 on the moving block 11 pushes the fixed plate 15 to fix the pipe, and the spring telescopic rod 14 is extended to make the cutting saw 13 contact with the pipe, and then start the second motor 12 to drive the cutting saw 13 to rotate to cut the pipe, and at the same time start the first motor 4 to drive the gear 7 to rotate, so that the gear 7 drives the positioning cover 6 and the cutting saw 13 to rotate through the meshing transmission with the tooth groove 8, wherein the fixed plate 15 only provides positioning for the pipe but does not clamp the pipe, so it will not cause the fixed plate 15 to move. The fixed plate 15 rotates simultaneously with the pipeline, and rotating wheels can be installed on the adjacent sides of the two fixed plates 15 to further fix the pipeline without hindering the cutting of the pipeline, so that the pipeline can be cut evenly and its cutting surface can be kept flat, thereby improving the practicality of the device, and the impurity box 203 can receive the residues generated during cutting, and the air pump 208 is started to suck air through the hose 209, which can absorb the residues and prevent dust during cutting. When the residue accumulates and gradually makes the impurity box 203 heavy, it will squeeze the pressure spring 207 at the bottom, so that the indicator rod 204 moves along the reserved groove 205 and indicates to the corresponding indicator groove 206. The current amount of accumulated impurities can be known by observing the indicator groove 206, so that it can be cleaned in time to prevent excessive impurities from affecting the normal operation of the device, thereby improving the reliability of the device.
