Abstract:
A motor element for a dental medical handpiece or a motor spindle has an elongated shank, rotatably mounted in which there is a drive shaft and a longitudinally-extending rod, a tool-holder for a tool within the rod, and a disconnectable coupling between the rod and the tool-holder. A locking element secures the coupling to prevent the coupling from becoming disconnected from the elongated shank. The locking/unlocking of the coupling is effected by a relative movement between the tool-holder and the tool.
