Latest Patents

Hiroumi holds a patent for a tool holder, which includes a holder body featuring a trunk and a grip tube. The design incorporates a pressure ring fitted around the grip tube, along with a nut that facilitates the axial movement of the pressure ring. A sleeve defines a pressure chamber around its outer periphery. The trunk is designed with cylinders that house pistons, which communicate with the pressure chamber through a channel. The hydraulic fluid sealed within the cylinders, communication channel, and pressure chamber allows for effective operation. When the nut is rotated, the pressure ring is axially moved, compressing the grip tube radially. This action pushes the pistons into their respective cylinders, increasing the pressure in the pressure chamber. Consequently, both the first holding hole in the grip and the second holding hole in the sleeve decrease in diameter, securely holding any tool inserted into these holes.
