Abstract:
1. A transmission system of an eyebrow-beautifying device, comprising: a needle assembly including a post, a needle projected upward from the post and a top sleeve for permitting the needle to either project therefrom or retract thereinto; a joining member including a lower section having a longitudinal cut, the joining member being coupled to a lower portion of the post of the needle assembly; a substantially zigzag transmission unit including a top section coupled to the lower section of the joining member and a bottom connecting member; a connecting unit including two vertical sections at both sides, a horizontal section on the top, a central slot between a bottom portion of two vertical sections, and a pivot hole through a bottom of the vertical sections and the slot; a lever member including a first aperture, a keyhole coupled to the connecting member, and two contacts at bottoms of both sides, the lever member being pivotably disposed in the slot by inserting a pin through the pivot hole; a slanted seat including a lower shaft sleeve; a motor including a shaft projected from a top and two diametrically disposed projections on the top; and a cylinder having a C-shaped section and including a central hole on a bottom for permitting the shaft sleeve of the slanted seat to pass through to be fastened around the shaft of the motor, and two diametrically disposed second apertures on the bottom, the second apertures being adapted to snugly receive the projections of the motor when the cylinder is rested on the motor, whereby a rotation of the shaft will rotate the slanted seat for moving the transmission unit up and down cyclically and projecting the needle from the top sleeve and retract thereinto cyclically.
