Publication number: 20240116154Abstract: A ratchet wrench and an external ratchet bushing anti-detachment and quick-release structure have an anti-detachment and quick-release assembly, a ratchet wrench and an external component. The anti-detachment and quick-release assembly can be pushed up and down by displacement and is magnetic, a ratchet wheel is arranged in the actuating end of the ratchet wrench, and the anti-detachment and quick-release assembly is fixed on one side of the ratchet wheel. When the external component is placed in the ratchet, it can be fixed by the magnetic adsorption of the anti-detachment and quick-release assembly. When disassembling, the external component is pushed against the external component to disengage from the ratchet. When the ratchet wrench is subjected to external force, the components will not be disengaged and damaged, and the overall structural assembly stability is good, so as to gain structural stability and allow safety use.Type: ApplicationFiled: February 22, 2023Publication date: April 11, 2024Inventor: Fu-Yuan Chen
