Latest Patents

One of his latest patents is a clutch mechanism designed for use in power-driven tools. This mechanism features a lock washer that presses balls and pins against a clutch cam with protrusions on its front face. The design ensures that when a large load is applied to a spindle during screw tightening, the outer edge of the lock washer deforms forward. This action allows the balls to ride over the protrusions of the clutch face, reducing the impact at the end of screw tightening and protecting the tool mechanism while minimizing shock to the operator's hand.

Another significant patent is for an impact tool that includes a body, a barrel mounted on the body, and a cylinder that is reciprocally moved by a drive mechanism. The cylinder features a communication groove that connects to the outside, along with multiple communication holes formed radially. The tool's striker is designed to move between two positions, allowing for effective impact operation while preventing idle impact when the tool bit is not pressed against a work surface.
