[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In the embodiment, Figure 1-4A cutting device for plastic drain pipes is provided. The utility model includes a base 1, a moving device 2 is arranged inside the base 1, the top of the moving device 2 is fixedly connected to a mounting plate 3, the top of the mounting plate 3 is fixedly connected to a support block 4, the top of the mounting plate 3 is fixedly connected to a protective frame 5, the interior of the protective frame 5 is provided with a pressing device 6, the top of the base 1 is fixedly connected to a support frame 7, the interior of the support frame 7 is fixedly connected to two hydraulic push rods 8, the bottoms of the two hydraulic push rods 8 are fixedly connected to a fixed frame 9 which is slidably connected to the support frame 7, the interior of the fixed frame 9 is fixedly connected to a cutting device 10, the front and rear walls of the interior of the support frame 7 are fixedly connected to electric push rods 11, the opposite sides of the two electric push rods 11 are fixedly connected to U-shaped frames 12, and the interiors of the two U-shaped frames 12 are rotatably connected to rollers 13.

[0028] Among them, the moving device 2 includes a motor 21 fixedly connected to the outside of the base 1, and the outside of the output shaft of the motor 21 is fixedly connected to a threaded rod 22 that is rotatably connected to the inside of the base 1, and the outside of the threaded rod 22 is connected to a transmission block 23 fixedly connected to the mounting plate 3 through a threaded transmission.

[0029] In this embodiment, during actual use, the start of the motor 21 drives the threaded rod 22 to rotate, and under the action of the thread, the transmission block 23 moves along the direction of the thread, and drives the upper mounting plate 3 to move.

[0030] Two sliding rods 14 are fixedly connected inside the base 1 , and two fixing blocks 15 are fixedly connected to the bottom of the mounting plate 3 and are slidably connected to the two sliding rods 14 .

[0031] In this embodiment, during actual use, when the mounting plate 3 moves, the fixing block 15 also moves, thereby causing the fixing block 15 to slide outside the sliding rod 14 to limit the moving direction of the mounting plate 3 .

[0032] The pressing device 6 includes a bolt knob 61 connected to the internal thread of the protective frame 5 , and the bottom of the bolt knob 61 is rotatably connected to a pressing plate 62 located above the support block 4 .

[0033] In this embodiment, during actual use, after the bolt knob 61 is turned, the pressing plate 62 will descend under the action of the thread and press and fix the drain pipe together with the support block 4.

[0034] The opposing surfaces of the support block 4 and the pressing plate 62 are both arc-shaped, and the top of the pressing plate 62 is fixedly connected to a telescopic rod 16 that is fixedly connected to the protective frame 5 .

[0035] In this embodiment, during actual use, the drain pipes are all circular, and the curved surfaces of the support block 4 and the pressing plate 62 fit the circle better. During the descent of the pressing plate 62, under the restriction of the telescopic rod 16, the pressing plate 62 will not rotate and can maintain the same direction as the support block 4. Buffer pads can be provided on the opposing surfaces of the support block 4 and the pressing plate 62 to prevent the drain pipe from being scratched while increasing the friction between them to make the fixation more stable.

[0036] The front and rear walls of the support frame 7 are both provided with sliding grooves, and the front and rear sides of the fixing frame 9 are both fixedly connected with slide plates 17 which are slidably connected to the two sliding grooves respectively.

[0037] In this embodiment, during actual use, when the hydraulic push rod 8 pushes the fixed frame 9 to descend, the slide 17 on the outside of the fixed frame 9 will slide in the support frame 7. The cutting device 10 is an electric cutting saw. When cutting, the slide 17 prevents the fixed frame 9 from shaking during the cutting process, thereby limiting its movement space.

[0038] Working principle:

[0039] First, place the drain pipe on the support block 4, and make the right side of the drain pipe pass through the two rollers 13. The roller 13 is set to a waist drum shape, which will limit the moving direction of the drain pipe. The roller 13 can limit the front and back of the drain pipe by pushing the two electric push rods 11, and the drain pipe located above the support block 4 is pressed and fixed by the pressing plate 62 by screwing the bolt knob 61. When cutting the drain pipe, start the motor 21, the drain pipe will move under the drive of the mounting plate 3, and the right side of the drain pipe will move with the rotation of the two rollers 13. The roller 13 also provides support and moving direction for the drain pipe. Finally, driven by the hydraulic push rod 8, the cutting equipment 10 will descend to cut the extended drain pipe.
