Description

Technical Field

[0001] The utility model relates to the technical field of pipeline thread processing, in particular to a tool for processing plastic pipe threads. Background Art

[0002] The outer wall of an existing plastic pipe usually needs to be processed with threads, and the threads are used to connect two adjacent plastic pipes. The thread processing tool is dedicated to processing threads. The existing thread processing tool includes a tool body, and a thread cutting edge is provided on one side of the tool body. The outer surface of the plastic pipe is cut by the pipe thread cutting edge, so that threads can be processed on the outer surface of the plastic pipe.

[0003] At present, when processing threads on the outer walls of some plastic pipes, the plastic pipes are fixed on a lathe, and then the plastic pipes are threaded by a thread cutter on a tool holder. However, when the thread cutter is installed and fixed, it is necessary to manually use a tool to turn the bolt on the tool holder downward to fix the thread cutter. This manual fixing method is relatively troublesome and laborious. At the same time, each time the thread cutter is installed, it is also necessary to insert several gaskets at the bottom of the thread cutter to adjust the height of the thread cutter, which is also relatively troublesome. Therefore, a tool for processing plastic pipe threads is now proposed. Utility Model Content
