[0002] A pipe fitting is a hollow, long strip of material with a usually circular cross-section. It consists of a pipe body and a connecting end. The pipe body is the main part of the pipe fitting, used to transport various fluids, gases or as a structural support component. The connecting end is usually flanged to achieve connection between pipe fittings and pipe fittings, and between pipe fittings and equipment to ensure the sealing and stability of the system. In the use of pipelines, it is usually necessary to cut the pipe fittings into specific lengths to adapt to different installation locations and connection requirements.

The appropriate saw blade can be selected according to the material and diameter of the pipe. However, it does not have the function of clamping and fixing the pipe to be cut.

[0015] Working principle: First, turn on the motor to drive the gear to rotate, which further drives the tooth plate to move.

Through the sliding of the clamping plate, the pipe to be cut can be clamped and fixed to ensure that the pipe will not be displaced due to external factors during the cutting process, thereby achieving the effect of improving the cutting accuracy.

[0016] When the tooth plate moves, it will also drive gear 2 to rotate on the outer wall of the limit block. When gear 2 rotates, the threaded connection between gear 2 and screw rod 1 will drive screw rod 1 to move up and down. When screw rod 1 moves up and down, it will drive the baffle to move up and down. Through the movement of the baffle, the baffle will automatically rise when clamping the pipe fitting, and will automatically fall when releasing the pipe fitting, thereby providing convenience for the operator when performing cutting operations.

[0017] First, turn on motor two. When motor two is working, it will drive screw two to rotate, and further drive the threaded block to move. When the threaded block moves, it will drive the sliding block to slide inside the connecting frame two through the slideway. When the threaded block moves, it will also drive the cutting disc to move, thereby realizing precise adjustment of the cutting disc position, reducing cutting errors, and achieving the effect of improving the processing quality of pipe fittings.

[0018] The present invention provides a pipe cutting mechanism having the following beneficial effects: 1. The present invention starts the motor to drive the gear to rotate, thereby driving the tooth plate to move. The connecting plate will move under the drive of the tooth plate. When the connecting plate moves, the fixing effect between the connecting plate and the clamping plate will drive the clamping plate to move synchronously, thereby clamping and fixing the pipe to be cut, avoiding displacement of the pipe during the cutting process and causing inaccurate cutting position, thereby achieving the effect of improving the processing quality of the pipe.

[0019] 2. In the present invention, when the tooth plate moves, it will also drive gear 2 to rotate, further driving screw rod 1 to move up and down. The baffle will move up and down synchronously under the drive of screw rod 1, and then when the pipe fitting is clamped and fixed, the baffle will automatically rise, and when the clamping is released, the baffle will automatically fall, thereby achieving the effect of improving the convenience of the operator during operation.

[0020] 3. The present invention starts motor 2 to drive screw rod 2 to move, thereby driving the threaded block to move. The sliding block will synchronously slide inside the connecting frame 2 under the drive of the threaded block. When the sliding block slides inside the connecting frame 2, the stability of the threaded block during movement can be improved. Since the threaded block and the cutting blade are fixedly connected, the cutting blade will move with the movement of the threaded block, thereby achieving precise adjustment of the position of the cutting blade, making the cutting position more accurate, and further achieving the effect of reducing the cutting error.
