Description

Technical Field

[0001] The utility model relates to the technical field of woodworking lathes, and more specifically to a tool rest for a woodworking lathe. Background Art

[0002] The tool rest is one of the components of a woodworking lathe. Its function is to support the processing tool to stabilize the tool position and save physical effort during the processing.

[0003] At present, the tool holder and tool handle of the common woodworking lathes on the market are mostly threaded connections, usually without locking parts, and are equipped with disc springs to reduce loosening caused by working vibration. However, the loosening of threads caused by vibration still cannot be effectively controlled. In addition, the adjustable handle on the existing woodworking lathe tool holder is usually directly pressed against the surface of the tool handle to lock the tool handle and the tool holder support. Since the contact area between the adjustable handle and the tool handle is small, the locking stability is often poor. Therefore, in view of this, the existing structure is studied and improved, and a woodworking lathe tool holder is provided, in order to achieve a more practical purpose. Utility Model Content
