Abstract (en)
A tool holding device is disclosed, and the tool holding device includes a base (100), a block (200), and a fastening member (300) for securing the block. The base (100) includes a receiving portion (130) defined between a countering wall (120) and a shoulder wall (110), a surface (150) defined adjacent to the shoulder wall perpendicularly and away from the countering wall, a penetrated hole (170) defined on the countering wall, and a positioning hole (180) communicating with the penetrated hole. The block includes a holding portion (210) held in the receiving portion, a handle (220) received in the penetrated hole, and a holding hole (250) for holding a chisel. The countering wall and the shoulder wall define an angle less than or equal to 90 degrees. Therefore, the counterforce bearing of the base and block are both enhanced to raise the strength of the tool holding device.
