Abstract (en)
[origin: US5157873A] A portable grinder (10) has a motor-driven drive shaft (15) and a quick-acting chucking device for a grinding tool (43), which comprises a spindle (20), coaxial with the drive shaft (15), which is braced against the drive shaft (15) by a spring (24) in the axial direction and can be displaced in the axial direction relative to the drive shaft (15) by means of a clamping lever (32). One external free end of the spindle (20) retains the grinding tool (43), which in a released position-with the free end of the spindle (20) extended and the spring (24) tensioned-can be removed from the free end, and in a tightened position-with the free end of the spindle (20) retracted and the spring (24) partly relaxed-is non-rotatably joined to the drive shaft. The free end is configured as a bayonet end (40) which extends though the grinding tool (43). An attachment collet (41) with a bayonet opening can be placed from outside onto the bayonet end (40).
