[0026] In this embodiment, after the pipe is placed between the auxiliary roller 3 and the driving roller 4, under the action of the pulley group 6, the driving motor 5 can drive the driving roller 4 to rotate, thereby controlling the rotation of the pipe. This makes it possible for the cutting disc 20 to cut the pipe by only breaking the outer wall of the pipe, which makes cutting more labor-saving and convenient.

[0027] Example 2, refer to Figure 3 A pipe cutting device for water and electricity installation, a scale plate 7 is fixedly connected to the outer wall of one side of the cutting table 1, and a slide 8 is slidably connected to the outer wall of the scale plate 7, a tightening knob 9 is screwed to the outer wall of one side of the slide 8, and a baffle 10 is welded to the outer wall of the top of the slide 8.

[0028] In this embodiment, a scale plate 7 is extended on the cutting table 1. The scale lines on the scale plate 7 are used to determine the cutting length of the pipe. After the baffle 10 slides along the scale plate 7 to determine the position, the tightening knob 9 can lock the slide 8. Each time the pipe is cut, it is only necessary to place the pipe against the baffle 10, thereby achieving fixed-length cutting of the pipe, simple operation, and high precision.

[0029] Reference Figure 2 The top of the cutting table 1 is provided with symmetrically distributed positioning wheels 11, and the bottom outer walls of the two positioning wheels 11 are screwed with bidirectional screw rods 12, which are rotatably connected to the bottom outer wall of the cutting table 1.

[0030] Reference Figure 1A base 13 is welded to the top outer wall of the cutting table 1, and a top frame 14 is welded to the top outer wall of the base 13. A servo motor 15 is fixedly connected to the top outer wall of the top frame 14 by bolts. The output shaft of the servo motor 15 is connected to a lifting screw rod 16 through a coupling.

Under the action of the pulley group 6, the driving motor 5 will drive the driving roller 4 to rotate, thereby controlling the rotation of the pipe. At the same time, the servo motor 15 drives the lifting screw 16 to rotate and control the slide plate 17 to move downward, and the fixed pressure wheel 22 will be close to the outer wall of the pipe. Finally, the cutting motor 19 drives the cutting disc 20 to rotate and cut the pipe.
