Description

Technical Field

[0001] This utility model relates to the field of quick-change angle of tightening shaft on lever arm, and in particular to a quick-change angle mechanism for tightening shaft. Background Technology

[0002] The quick-change angle mechanism for tightening shafts is a support device used in tightening stations to quickly change the angle of the tightening shaft on the lever arm. The tightening shaft is fixed on the lever arm and needs to flexibly adapt to different tightening angles at the same work station. With the continuous development of technology, people's requirements for quick-change angle mechanisms for tightening shafts are also getting higher and higher.

[0003] Existing tightening shafts have certain drawbacks in use. They are directly fixed to the lever arm, and the tightening structure is relatively simple. They cannot adapt to different angles at the same work position and cannot be easily and quickly adjusted, which brings certain adverse effects to the actual use process. To address this, we propose a quick-change angle mechanism for tightening shafts. Utility Model Content
