Is a shaft 19 driven by a motor which is a rotary drive source 18.
It is attached to. The teeth 15 are formed such that the rising angle of the inclined surface in the tightening direction of the chuck 11 is smaller than the rising angle of the inclined surface in the tightening direction of the chuck 11, and therefore, the tooth 15 is not necessarily attached when the chuck 11 is removed. A torque limiter that operates a torque equal to or greater than the torque is configured.
The high torque side of the tooth 15 may be a right angle or more with no torque limitation.

That is, after confirming that the stopper pin 23 protrudes and the main shaft 10 is fixed , the shaft portion S of the tool T is chucked.
When it is inserted into the plug 11 and the switch is turned on, the shaft 19 on the drive source 18 side rotates in a fixed direction, and the engaging members 16 and 17 rotate the drive shaft 14 with a lower torque. In this case the planetary gear 13b rotates the chuck 11 at a predetermined torque tightening
Engagement and engagement of engaging members 16 and 17 when a certain torque is reached.
The switch 31 detects that the drive source 18 is turned off.
Since it is stopped , the blade T is in the attached state.
