Description

Technical Field

[0001] This utility model relates to the field of pipe cutting, and specifically to a hand-held cutting machine for PVC pipes. Background Art

[0002] In the processing of PVC pipes, a hand-held cutting machine is a common tool. Currently, the cutting methods for PVC pipes mostly rely on manual saws or simple electric tools. During the cutting process, the pipe needs to be manually held. To ensure the cutting accuracy, it is often necessary to hold the pipe close to the cutting position, which is prone to injury and has a low degree of mechanization. Content of the Utility Model

[0003] To overcome the above deficiencies, this utility model provides a hand-held cutting machine for PVC pipes.

[0004] The technical solution adopted by this utility model is as follows:

[0005] A hand-held cutting machine for PVC pipes includes an angle grinder. The output shaft at the left end of the front side of the angle grinder is fixedly connected with a saw blade. A protective cover is provided outside the saw blade, and the protective cover is fixedly connected with the outer wall of the angle grinder. A handle is fixedly connected to the right side of the top of the angle grinder. A rotating shaft is fixedly connected to the middle of the front side wall of the angle grinder. A cantilever is rotatably connected to the outer wall of the rotating shaft. A straight plate is fixedly connected to the end of the cantilever away from the rotating shaft. An arc plate is fixedly connected to the end of the straight plate. The straight plate and the arc plate are of an integral structure. Cuts are provided at the top of the arc plate and the straight plate, and the cuts penetrate the arc plate to the left and are in clearance fit with the saw blade. A connecting rod is fixedly connected to the top of the cantilever. The connecting rod is arc-shaped. A turning handle is vertically fixedly connected to the top end of the front side wall of the connecting rod.

[0006] A limiting post is fixedly connected to the middle of the front side wall of the angle grinder, and the limiting post is located at a position slightly lower and to the right of the rotating shaft.

[0007] The arc plate is in the shape of a two-thirds circular ring.

[0008] Advantages of this Utility Model

[0009] This utility model can achieve the cutting of pipes through simple lifting and rotating actions, without complex operations, reducing the operation difficulty, improving the work efficiency, and increasing the degree of mechanization. And the arc plate is used to limit the pipe, avoiding injury caused by being too close during manual limitation, thus improving the safety. Description of the Drawings

Specific embodiments

[0014] As Figures 1-3 shown: A hand-held cutting machine for PVC pipes includes an angle grinder 1; the output shaft at the left end of the front side of the angle grinder 1 is fixedly connected with a saw blade 2, and the outer side of the saw blade 2 has a guard 3, and the guard 3 is fixedly connected with the outer wall of the angle grinder 1. The right side of the top of the angle grinder 1 is fixedly connected with a handle 4, and the middle part of the front side wall of the angle grinder 1 is fixedly connected with a rotating shaft 5. The outer wall of the rotating shaft 5 is rotatably connected with a cantilever 6. One end of the cantilever 6 far from the rotating shaft 5 is fixedly connected with a straight plate 7, and the end of the straight plate 7 is fixedly connected with an arc plate 8. The straight plate 7 and the arc plate 8 are of an integral structure. An incision 9 is provided at the top of the arc plate 8 and the straight plate 7. The incision 9 penetrates the arc plate 8 to the left, and the incision 9 is in clearance fit with the saw blade 2. The top of the cantilever 6 is fixedly connected with a connecting rod 10. The connecting rod 10 is arc-shaped, and the top end of the front side wall of the connecting rod 10 is vertically fixedly connected with a turning handle 11.

[0015] A limit post 12 is fixedly connected to the middle part of the front side wall of the angle grinder 1, and the limit post 12 is located at a position slightly lower and to the right of the rotating shaft 5.

[0016] The arc plate 8 is in the shape of a two-thirds circular ring.

[0017] The arc plate 8 can limit the pipe inside to prevent it from falling off.

[0018] First, the PVC pipe 13 to be cut is passed through the inner side of the arc plate 8 and placed inside the arc plate 8. Since the arc plate 8 is in the shape of a two-thirds circular ring, it can well accommodate and fix the pipe, ensuring that the PVC pipe 13 will not shake or shift during the cutting process;

[0019] After the PVC pipe 13 is properly placed, ensure that the cutting position of the PVC pipe 13 is aligned with the saw blade 2. Start the angle grinder 1 to drive the saw blade 2 to start rotating. By holding the handle 4 to lift the angle grinder 1, and at the same time grasping the turning handle 11 with the other hand, when lifting the turning handle 11 upward, the cantilever 6, the straight plate 7 and the arc plate 8 will rotate clockwise with the rotating shaft 5 as the center. During this process, the PVC pipe 13 will be pressed under the saw blade 2;

[0020] Continuously lift the turning handle 11 upward with force. While the saw blade 2 is rotating, it will gradually cut into the pipe along the clearance fit of the incision 9. Since the incision 9 penetrates the arc plate 8 to the left, it can provide a guide to enable the saw blade 2 to cut along a predetermined path;

[0021] After the PVC pipe 13 is completely cut, release the throttle grip 11 to let the cantilever 6, the straight plate 7 and the arc plate 8 return to their initial positions, preparing for the next cutting.
