Claims

[Scope of utility model registration request]

A hollow shaft 1 that is screwed onto the rotating shaft of a power tool has a large-diameter front cylinder part 3 at the tip thereof, and a square shaft part 16 and a flange provided in the shaft-equipped polishing tool are inside the hollow shaft 1 and the front cylinder part 3. A chuck main body 6 is provided with a square shaft hole 4 into which a shaped base 15 is fitted, and a socket 5, and holds a steel ball 7 in and out of the hollow shaft 1 at an intermediate position of the square shaft hole 4.
A projecting edge 9 is fitted into the hollow shaft 1 and has an annular recess 10 in front of the projecting edge 9, which engages the steel ball 7 into an engagement groove 17 provided in the square shaft portion 16 of the shafted tool 14. and a cylindrical finder 8 which is usually stopped and held at the stepped part 2 of the front cylinder part 3 by a spring 13 interposed between the projecting edge 9 and a stop ring 12 fixed to the hollow shaft 1. Quick check for power tools.
