Abstract: The cutting shank of an instrument to be received in the head of a contra-angle of a dentistry handpiece is clamped in position with a pushed-button control device which is displacable counter to a tensioning spring. The control device generally takes the form of at least one reversal element for receiving pressures responsive to movements of the push-button and for converting such movements into a traction movement exerted by the reversal element on the pusher which is used to control the collet chuck which receives the shank of the instrument.

Abstract: The invention relates to a device for attaching instruments. The device includes a rotary shaft intended to accept the instrument and rotationally drive it. The device also has at least one peg that can be retracted elastically until it can fit into the latching groove, thus axially retaining the instrument. A catch rotates as one with the rotary shaft and, in combination with the rotary shaft, gives the shape combined with that of the driving flat of the shank of the instrument. There is the particular feature of retracting radially or longitudinally if the flat is correctly orientated and resuming the position in which it rotationally drives the instrument. The flat of the instrument generally adopts the appropriate position when turned as soon as the slightest rotational force is applied to it. The instrument is released by action on a push-button, which moves the peg aside or radially retracts it.
