As shown in fig. 2 and 3, the circular track 111 is arranged in a circular shape, the center line of the circular track 111 and the center line of the first shaft hole 112 are arranged in a parallel and staggered manner, and the center of the circular track 111 is the movement center of the transmission rod 14. Since the rotation center of the disc cam 11 (i.e., the center of the first shaft hole 112) does not coincide with the movement center of the transmission lever 14, a biased shock is generated during the transmission. In order to avoid the phenomenon of deviation vibration in the transmission process, a notch 113 is formed at the edge of the disc cam 11, and the distance between the notch 113 and the center line of the first shaft hole 112 is smaller than the distance between the notch 113 and the center line of the annular track 111, so that the center of gravity of the disc cam 11 is located at the first shaft hole 112, the design enables the transmission process to be smoother, the transmission process of the transmission mechanism 10 conforms to the sine or sine-like curve law, and the vibration amplitude of the transmission mechanism 10 can be effectively reduced.
In one embodiment, as shown in fig. 4 and 5, the circular track 111 is disposed in an elliptical shape, the center line of the circular track 111 coincides with the center line of the first shaft hole 112, the motion process of the transmission rod 14 conforms to the sine or sine-like curve law, the vibration amplitude of the whole transmission process is small, and the noise is low.

It will be appreciated that the first pin 15 is in interference fit with the inner wall of the first through hole 141, so that the first pin 15 and the transmission rod 14 are of a one-piece structure.
In one embodiment, the transmission mechanism 10 further comprises a piston 16, one end of the piston 16 is connected with one end of the transmission rod 14 far away from the first bearing 13, the other end is connected with a massage head 20, the piston 16 and the transmission rod 14 synchronously perform reciprocating linear motion, and when the piston 16 performs reciprocating linear motion, the massage head 20 performs reciprocating vibration based on the motion of the piston 16 to achieve the purpose of knocking massage.
In one embodiment, as shown in fig. 2, a second through hole 142 is formed at an end of the transmission rod 14 away from the first bearing 13, and a second bearing 17 is disposed in the second through hole 142; the transmission mechanism 10 further includes: and the second pin joint 18, the second pin joint 18 is arranged in the second bearing 17 in a penetrating manner, one end of the second pin joint 18 facing the piston 16 is connected to the piston 16, and the transmission rod 14 is in an integrated structure based on the second pin joint 18 and the piston 16 and can drive the second pin joint 18 and the piston 16 to perform reciprocating linear motion based on the second bearing 17. It can be understood that the transmission rod 14 drives the piston 16 to perform reciprocating linear motion through the second bearing 17, and further drives the massage head 20 connected with the piston 16 to perform knocking massage on the human body, and the second bearing 17 can make the rotation process smooth and reduce the vibration.
The piston 16 extends towards the second bearing 17 to form a boss 161, the boss 161 penetrates into the second through hole 142, the boss 161 is formed with a through hole 1611 corresponding to the second bearing 17, and one end of the second pin joint 18 facing the through hole 1611 penetrates into the through hole 1611, so that the second pin joint 18 and the boss 161 are of an integrated structure. Further, a screw thread is formed on the inner wall of the boss 161, and one end of the second pin 18 facing the through hole 1611 is screwed into the through hole 1611.

Since the shape of the profile curve of the circular track 111 determines the shape of the displacement curve of the transmission rod 14, the circular track 111 only needs to be designed to have a motion trajectory conforming to a sinusoidal or quasi-sinusoidal structure (such as a circle, an ellipse, etc.), so that the transmission rod 14 can smoothly go over the "dead point" position.
