Description

Technical Field

[0001] This utility model relates to the field of flexible tap chuck structure technology, and in particular to a flexible tap chuck structure. Background Technology

[0002] Existing flexible tap chuck structures, with components such as adjusting rings, facilitate use. However, the threaded connection of the adjusting ring can loosen over time, leading to shaking or detachment during use. For example, Chinese patent disclosure "A Flexible Tap Chuck Structure" (application number: CN202121305678.2) includes a tool holder and a tap. One end of the tool holder is fixedly equipped with a tool seat, and an adjusting ring is threadedly connected to the external part of the tool seat. Symmetrically arranged sliders are slidably mounted on one side of the adjusting ring. Each slider has an "L"-shaped support rod fixed to one side by a countersunk screw. The other end of the support rod is fixedly connected to an adjusting rod. This structure facilitates use, but the threaded connection of the adjusting ring can loosen over time, leading to shaking or detachment during use, thus limiting its usability.
