发明名称 Gum massage device
摘要 A gum massage device includes a soft tipped wand connected to a power unit. The power unit has a rotary shaft that is engaged in a socket in the base of the wand. The socket is angularly offset from the normal axis of the shaft and wand, and a member is connected between the wand and power unit to resiliently hold the shaft and wand in axial alignment. Rotation of the shaft caused the wand to oscillate in a desirable gum massaging motion.
