Abstract
An oral hygiene device has a handle and an automatic stem insertion system and comprises a pair of keys on the motor driven shaft. A bore receives the shaft, and slots receive the keys. A pair of sleeves each having a ramp for receiving and engaging the keys. When coupling the stem to the handle and with a camming action of the keys on the ramp, the ramps guide the keys into the slots. A radially extending flange is on the base of the shaft; and a pair of flexible arms having a recess receive the flange. Upon coupling the stem to the handle, the flange engages the arms and flex the arms outwardly and further movement of the stem onto the handle causes the flange to enter the recesses with a snap action; and upon withdrawal of the stem from the handle, the flange causes the arm to flex outwardly to release the flanges from the recesses.
