[0031] like Figure 1-3,5,7-8, the movement body 2 includes two symmetrically arranged swing arms 201, kneading and knocking massage heads 202 arranged at both ends of the swing arms 201, a kneading drive component 203 for driving the kneading and knocking massage heads 202 to complete the kneading action, and a knocking drive component 204 for driving the kneading and knocking massage heads 202 to complete the knocking action. The swing arm 201 is in a "√" shape, and the swing arm 201 integrates the functions of a rocker arm and a swing arm, and a ball head pull rod connector 214 is fixedly provided thereon. The kneading drive component 203 includes a kneading eccentric shaft 205 and a kneading motor 206 for driving the kneading eccentric shaft 205 to move. The two ends of the kneading eccentric shaft 205 are connected to the corresponding supporting side plates 301 through bearings. The lowest end of the swing arm 201 is sleeved on the kneading eccentric shaft 205. The longer end and the shorter end are respectively arranged on both sides of the kneading eccentric shaft 205; the knocking drive assembly 204 includes a knocking motor 207, a small pulley 208 connected to the output shaft of the knocking motor 207, a large pulley 210 connected to the small pulley 208 through a belt 209, and a ball head pull rod 211, the large pulley 210 is installed at both ends of the knocking eccentric shaft 212, one end of the ball head pull rod 211 is connected to the knocking eccentric shaft 212 through a ball head pull rod fixing seat 213, the other end of the ball head pull rod 211 is connected to the corresponding swing arm 201 through a ball head pull rod connector 214, the ball head pull rod fixing seat 213 is sleeved on the knocking eccentric shaft 205, and the two ends of the ball head pull rod 211 are respectively hinged to the ball head pull rod fixing seat 213 and the ball head pull rod connector 214.

[0033] Working principle of the present invention:

[0034] like Figure 1As shown, when the preload elastic component 4 is in the preload state, the kneading drive component 203 is not affected by external force, its height is at the maximum value, and the movement body 2 is in a natural state. When the kneading drive component 203 is subjected to back pressure, the movement body 2 and the support frame 3 rotate around the kneading eccentric shaft 205 in a seesaw manner. The swing arm 201 on one side of the kneading eccentric shaft 205 is longer, and the swing arm 201 on the other side is shorter. According to different human body shapes and back shapes, the kneading drive component 203 rotates to the most suitable position under the action of a smaller external force, and a limited baffle 110 is set on the walking outer frame 101. When the supporting side plate 301 rotates to contact the bottom of the limited baffle 110, the entire kneading drive component 203 drops to the lowest point. When the supporting side plate 301 rotates to directly contact the upper part of the walking outer frame 101, the kneading drive component 203 rises to the highest point. The preload elastic component 4 not only plays a buffering role, but also plays a partial limiting role. The overall thickness of the movement is maintained within a small range during the entire rotation process, the kneading drive component 203 achieves a larger stroke within the range, and the kneading drive component 203 achieves flexible floating under the action of a small external force to meet the back massage requirements of different human bodies.

[0035] Although the present invention has been described in detail above by general description and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made on the basis of the present invention. Therefore, these modifications or improvements made on the basis of not departing from the present invention all belong to the scope of protection claimed by the present invention.
