Abstract

This utility model discloses a threading tool with a telescopic tool holder, relating to the field of threading tool technology. The utility model includes a tool holder, a sliding sleeve slidably connected to the surface of the tool holder, a threading head fixedly connected to the top of the sliding sleeve, and a first placement groove inside the tool holder. A vertical plate is fixedly connected inside the first placement groove, and limit rods are fixedly connected to both sides of the vertical plate. This utility model, through the sliding connection between the sliding sleeve and the tool holder, combined with an internal spring-driven locking mechanism, achieves rapid adjustment of the threading tool length. The user only needs to push the push button downwards to release the sliding sleeve's limit through the cooperation of the wedge block and the fixed plate, allowing it to slide freely to the desired length. Pushing the push button upwards then re-limits the sliding sleeve through the wedge block and the fixed plate. This allows the tool to adapt to different threading depths, eliminating the need for frequent tool changes, significantly reducing production costs, and improving processing efficiency.
