[0012] Furthermore, a plurality of oil storage grooves are arranged on the outer peripheral surface of the eccentric cam.

[0013] The oil storage tank can be filled with grease to lubricate the transmission rod when the sleeve joint of the transmission rod is sleeved on the eccentric cam for movement, so as to improve the transmission efficiency of the transmission rod and increase the service life of the transmission rod.

[0014] Furthermore, the first massage wheel and the second massage wheel are provided with a kneading portion at a position away from the output shaft.

[0015] The kneading part provided above can further enhance the massage strength of the massage wheels when the output shaft drives the first massage wheel and the second massage wheel to rotate eccentrically, so that the user can obtain a better use experience.

[0016] Furthermore, it also includes a mounting seat, and two ends of the mounting seat are respectively provided with a first mounting groove for placing the massage wheel and a second mounting groove for placing the scraping board; the scraping board is partially placed in the second mounting groove.

[0017] Part of the scraping board is sunken into the second mounting groove, so that it can provide a certain guiding effect on the scraping board when it reciprocates, and the scraping board can rotate better in the second mounting groove, so that it can more easily change the direction of movement when the scraping board is at its movement limit, thereby improving the smoothness of the reciprocating motion of the scraping board.

[0018] Furthermore, an axle rod and a linkage rod are respectively provided at opposite ends of the scraping board. The axle rod is integrally formed with the scraping board and is protrudingly arranged on both sides of the scraping board. The linkage rod is passed through the transmission rod and the scraping board to form a transmission connection between the two.

[0019] The shaft rod and the scraping board are integrally formed to form a stable connection relationship, so as to avoid the problem of transmission failure or inadequate transmission resulting in unsmooth movement of the scraping board due to unstable connection; and the linkage rod is passed through the transmission rod and the scraping board to form a fixation between the two, so that when the transmission rod moves, the scraping board can be moved back and forth through the linkage rod, and the scraping board can be swung left and right with the shaft rod as the axis through the linkage rod, thereby forming a reciprocating motion of the scraping board.
