Description

Technical Field

[0001] The present application relates to the technical field of PVC pipe cutting, and more specifically, to a PVC pipe cutting device. Background Art

[0002] Polyvinyl chloride (PVC) pipe is a common plastic pipe made by polymerizing chlorine and ethylene. It has excellent corrosion resistance, mechanical strength and weather resistance, and is widely used in construction, municipal engineering and industrial fields. PVC pipe has the characteristics of light weight, easy installation and low cost, and performs well in transporting water, gas, chemicals, etc. Its unique physical and chemical properties make PVC pipe a popular pipe material, widely used in various application scenarios such as drainage, sewage, water supply, ventilation, etc.

[0003] The document with prior art publication number CN 218255431 U provides a PVC pipe cutting device, which rotates an adjustment part at one end of a screw threadedly connected to a clamping frame to rotate the screw and push a movable arc plate to move toward a fixed arc plate until the inner arc surface of the movable arc plate abuts against the surface of a pipe, thereby facilitating fixing and holding the pipe. The screw can be driven to rotate by an adjustment member. Since the two clamping assemblies are connected by a connecting strip, the rotation of the screw can drive the two clamping assemblies to move synchronously, so that the PVC pipe clamped by the clamping assembly can be fine-tuned left and right for the cutting position, making the cutting more precise.

[0004] Although the above-mentioned prior art solution can achieve the relevant beneficial effects through the structure of the prior art, it still has the following defects: the above-mentioned PVC pipe cutting device has a complex structure, is troublesome to operate, cannot quickly cut the PVC pipe, and the use effect is not very good.
