The present invention refers to a transmission mechanism of an eyebrow tattoo machine, which includes an eccentric rotation shaft connected to a driving axle of a motor and having a bottom end configured to rotate eccentrically with respect to the driving axle, an upper bearing coupled with the bottom end of the eccentric rotation shaft, a position-limiting cover longitudinally provided with a position-limiting groove, and a swinging rod element mounted to the upper bearing and provided with a swinging rod and a position-limiting rod on two sides respectively. Since the position-limiting rod is only allowed to swing up and down in the position-limiting groove when the eccentric rotation shaft drives the upper bearing and the swinging rod element, the end of the swinging rod away from the upper bearing can swing up and down and then drive a tattoo needle to move vertically up and down through a lateral bearing. |

1. A transmission mechanism of an eyebrow tattoo machine, comprising:
an eccentric rotation shaft having an upper end connected to a driving axle of a motor and a bottom end configured to rotate eccentrically with respective to the driving axle; an upper bearing having an inner periphery coupled with the bottom end of the eccentric rotation shaft so as for the eccentric rotation shaft to drive the upper bearing into rotation; a position-limiting cover longitudinally formed with a position-limiting groove and located adjacent to the eccentric rotation shaft; a swinging rod element fixedly mounted around an outer periphery of the upper bearing, having a side protrudingly provided with a swinging rod, and having another side protrudingly provided with a position-limiting rod, wherein the position-limiting rod extends into the position-limiting groove such that, when the eccentric rotation shaft drives the upper bearing and thereby drives the swinging rod element, the position-limiting rod can only swing up and down in the position-limiting groove, thereby causing an end of the swinging rod that is away from the upper bearing to swing up and down; a lateral bearing having an inner periphery coupled with the swinging rod so as for the swinging rod to drive the lateral bearing into up-and-down swinging motion; and a linking member having a fork portion and a pivoting element, wherein the pivoting element is fixedly mounted around an outer periphery of the lateral bearing and pivotally connected to the fork portion such that, when the lateral bearing swings up and down, the pivoting element is driven by the lateral bearing to move up and down, thereby causing the linking member to move up and down. |
