摘要： PROBLEM TO BE SOLVED: To prevent the occurrence of a problem even when an impact tool is operated in an impact operation mode by mistake in using an output bit for a non-impact operation mode.
SOLUTION: This adapter 50' for an impact tool includes an impact operation mode of applying rotation and axial impact to the output bit 50 and a non-impact operation mode of applying only rotation to the output bit 50, and further includes a chuck part 59 corresponding to an SDS plus type shank. The adapter is provided with a groove 500 where a slip-off preventing ball and a slide groove 501 where a rotation transmitting internal projection is slid and engaged. The slide groove has an axial length shorter than the slide groove in the SDS plus type shank. The axial mounting position regulation of the slide groove and the internal projection limits the mounting position to the chuck part to a position not to come into contact with an impact member in the impact tool.

摘要： PURPOSE:To simply and speedily perform a locking operation by utilizing the rotative drive of a shaft via the operation of a power tool while grasping a rotary ring to release a locking means preventing the rotation of a sleeve against a shaft. CONSTITUTION:When a tool 4 is to be fitted, the rear end section of the tool is inserted through a tip opening, a power tool is operated while a rotary ring 2 is grasped, and a shaft 1 is rotated. Since a locking material 82 is pushed up by a tooth 11 at this time, a sleeve 8 can be rotated against the shaft 1. As a result, the sleeve 8, a taper bush, a guide block 7 and a float screw 6 are rotated in relation to the shaft 1, thus a float screw 6 screwed with the shaft 1 is advanced and moves claws 5 forward. As a result, individual claws 5 are concentrated to the center in the radial direction, and the tool 4 is fastened.

摘要： PURPOSE:To promote the sure holding of a tool while to easily operate its mounting and removal, by equipping a device with a rotary ring engaging means which holds a rotary ring to be placed in an unlocked condition, in case of the tightening device equipped with a tightening pawl and a lock means. CONSTITUTION:In order to mount a tool, it is inserted from a point end opening, and a rotary ring 2 is rotated while gripping a handle 3. Here each pawl 5, whose blade piece is positioned between a guide block 7 and the internal peripheral surface of a tapered bush 25, concentrates to the center in the diametric direction tightening the tool. Next to remove the tool, the rotary ring 2, after it is moved to a side of the handle 3, is turned. Here an engaging pawl 34 is stopped to an engaging groove 27 by elasticity in a hinge part 33. In this way, the necessity for a hand to hold a condition that the rotary ring 2 is moved to the side of the handle 3 is eliminated, accordingly the tool comes to easily attain its mounting and removal operation.
