The machine body 1 is provided with a mounting rack 1A connected with the swinging mechanism 3, and the mounting rack 1A comprises a guide rail for the movement of the massage machine core.

The inner side of the side plate 2 is provided with a containing groove for containing the hand, and a massage air bag (not shown) can be arranged in the containing groove.

With reference to fig. 3A to 3C, the swing link mechanism 3 includes a first curved lever 5 and a second curved lever 6, the first curved lever 5 is located above the rear side of the second curved lever 6, two ends of the first curved lever 5 are respectively pivoted on the mounting bracket 1A and the side plate 2 of the machine body 1, two ends of the second curved lever 6 are respectively pivoted on the mounting bracket 1A and the side plate 2 of the machine body 1, and the pivot axes of the two ends of the first curved lever 5 are parallel to the pivot axes of the two ends of the second curved lever 6.

In this embodiment, the limiting mechanism 4 is disposed between the machine body 1 and the swing link mechanism 3, and with reference to fig. 6A to 8B, when the swing link mechanism 3 is driven by the side plate 2 to switch between different swing states (fig. 7B illustrates a first swing state, fig. 8B illustrates a second swing state), the limiting mechanism 4 is correspondingly driven to switch between different limiting states (fig. 7B illustrates the first limiting state, fig. 8B illustrates the second limiting state), so that the swing link mechanism 3 correspondingly maintains at different swing states. Referring to fig. 4A to 5, in the present embodiment, the limiting mechanism 4 includes a limiting member 4A, a sliding member 4B, a shaft rod 4C, a wear-resistant pad 4D, and a connecting seat 4E. Referring to fig. 3B, the limiting member 4A is pivotally connected to the mounting frame 1A of the machine body 1, and the pivot axis of the limiting member 4A is parallel to the pivot axes of the two ends of the first curved bar 5 and the pivot axis of the two ends of the second curved bar 6. The sliding member 4B is rotatably connected to the first curved bar 5 by the shaft 4C and the connecting seat 4E, and the rotation axis of the sliding member 4B is parallel to the pivot axis of the limiting member 4A. The connecting seat 4E is in a shape like a Chinese character ji, and is fixed on the first curved bar 5 through connecting lugs at two sides, and the shaft lever 4C is a T-shaped shaft lever and passes through the connecting seat 4E from top to bottom, so that the shaft lever 4C is indirectly connected on the first curved bar 5. The sliding part 4B is a shaft sleeve part which is rotatably sleeved on the shaft lever 4C, the wear-resistant gasket 4D is sleeved on the shaft lever 4C, and the wear-resistant gasket 4D is positioned between the limiting part 4A and the connecting seat 4E.
