[0002] Drain pipes are mainly used to drain rainwater, sewage, farmland irrigation and drainage. Drain pipes are divided into plastic drain pipes, concrete pipes and reinforced concrete pipes. Plastic drain pipes are made of sanitary-grade polyvinyl chloride resin as the main raw material, with appropriate amounts of stabilizers, lubricants, fillers, color enhancers, etc., and are extruded by a plastic extruder and injection molded by an injection molding machine. During the installation of drain pipes, a cutting machine is usually required to cut the length of the drain pipe to make the length suitable for installation. Under the existing technology, a circular saw cutting machine is often used to cut the drain pipe, so that the cut end of the drain pipe is smooth and easy to install. The existing technology has the following problems:

A handle is installed at the left end of the cutting machine support frame 2, and the handle drives the cutting machine support frame 2 to rotate around the fixed shaft 14, so that the cutting machine body 3 rotates downward and contacts the drain pipe on the top of the workbench 4, thereby cutting the drain pipe. At the same time, the rotation angle of the cutting machine support frame 2 is limited by the vertical rod 6 to prevent the cutting machine support frame 2 from rotating too much. After the cutting machine support frame 2 is released, the spring 13 rebounds and drives the cutting machine support frame 2 to rotate, thereby resetting the cutting machine body 3.

The two sliding rods 4241 drive the gears 4242 and the rotating shaft 422 on both sides to rotate in opposite directions through the tooth grooves 4243, so that the two rotating shafts 422 drive the rotating clamping rods 421 on both sides to rotate outward synchronously, thereby exposing the arc-shaped groove 43 to facilitate the installation of the drain pipe. After loosening the vertical pressure plate 4232, the spring 2 4231 drives the vertical pressure plate 4232 to rebound, so that the rotating clamping rod 421 rotates and presses the outside of the drain pipe. The drain pipe is kept straight and prevented from tilting by the two rows of rotating clamping rods 421. The vertical pressure plate 4232 is prevented from resetting too much and causing detachment by the connecting rod 4235, thereby fixing the drain pipe.

[0033] The following is a detailed description of the working principle of the drainage pipe cutting machine.

[0034] like Figure 1-7 As shown, the vertical pressure plate 4232 is pulled downward, and the vertical pressure plate 4232 drives the horizontal connecting plate 4233 and the sliding rod 4241 to move downward, so that the spring 2 4231 is compressed, and the vertical pressure plate 4232 is prevented from tilting by the limit rod 4234. The two sliding rods 4241 drive the gears 4242 and the rotating shaft 422 on both sides to rotate in opposite directions through the tooth grooves 4243, so that the two rotating shafts 422 drive the rotating clamping rods 421 on both sides to rotate outward synchronously, thereby exposing the arc groove 43 to facilitate the installation of the drain pipe, and the drain pipe is placed inside the arc groove 43. After the vertical pressure plate 4232 is released, the spring 2 4231 drives the vertical pressure plate 4232 to rebound, so that the rotating clamping rod 421 rotates and presses the outside of the drain pipe, The two rows of rotating clamping rods 421 keep the drain pipe straight to prevent it from tilting, and the connecting rod 4235 prevents the vertical pressure plate 4232 from resetting too much and causing it to detach, thereby fixing the drain pipe. The motor 51 drives the screw rod 52 to rotate, and drives the connecting plate 44 and the slider 45 to move along the slide rail 7 through the threaded hole in the middle of the connecting plate 44, thereby driving the workbench 4 to move. As the workbench 4 moves, the drain pipe inside the arc-shaped through groove 43 contacts the cutting machine body 3 in turn, thereby completing the cutting, opening the rotating baffle 411, and sliding the folding fixing rod 414 so that the folding fixing rod 414 is inserted into the inside of the handle 412, thereby fixing the rotating baffle 411, so that the debris inside the workbench 4 is discharged through the through groove on the side of the baffle 41.

[0035] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention.
