More Information
Summary:A dental handpiece having a rear housing containing a power assembly and a front housing containing a chuck assembly. The front housing is provided with an assembly for quickly connecting and removing the same from the rear housing. Additionally, a novel mechanism is provided for securing a bur in the chuck assembly. The mechanism includes a rotatable sleeve having a pair of balls secured in grooves therein. Rotation of the sleeve moves the balls in grooves of a linearly moving connector which in turn moves the collet of the chuck assembly linearly. Thus, rotational motion is translated into linear motion to advance and retract the collet securing the shank of the dental bur.
