This design makes it easy to adjust the massage intensity of the massage wheel 9 or the massage punch 10 on the user's back, and has a simple structure and is easy to operate. At the same time, through the cooperation of the slide groove 34 and the slider 35, the positioning plate 18 can smoothly drive the massage wheel 9 and the massage punch 10 to move.

[0026] Working principle:

[0027] First, the user sits on the seat cushion 3 , and the user is supported by the seat plate 1 , the first cylinder 6 and the movable frame 2 , and the user's back leans on the backrest 5 through the cushion 8 , and both arms can be placed on the armrests 4 .

[0028] When the user needs to massage the back, the heating wire 36 and the second cylinder 32 are started, and the telescopic end of the second cylinder 32 drives the mounting plate 19 to move in the user's sitting depth direction through the connecting rod 33, and the mounting plate 19 then drives the positioning member 20, the placement box 27, the mounting box 11 and the positioning block 30 thereon to move toward the user's back. In this process, the mounting plate 19 drives the slide groove 34 to slide relative to the slider 35. When the mounting box 11 abuts against the user's back, the second cylinder 32 stops working.

[0029] Next, the user starts the second motor 22, and the second motor 22 drives the screw rod 23 to rotate through its output end, thereby making the sleeve 24 move vertically on the screw rod 23. The sleeve 24 that moves vertically drives the installation box 11 to move back and forth vertically through the placement box 27, the second rotating shaft 29, the third rotating shaft 31, the positioning block 30, the limit block 26 and the limit rod 25. During this process, the limit block 26 is always vertically slid on the limit rod 25. When the installation box 11 moves to the part that the user needs to massage, the second motor 22 stops working.

[0030] Afterwards, the first motor 12 is started, and the first motor 12 drives the massage wheel 9 to rotate out of the first massage hole 16 correspondingly through the first rotating shaft 15 thereon, so as to perform a beating massage on the user's back.

[0031] When the user needs to perform impact massage on a certain position of the back, the first motor 12 is stopped, and the third motor 28 is started, and the second rotating shaft 29 on the third motor 28 drives the installation box 11 and the third rotating shaft 31 to rotate. At this time, the installation box 11 is turned over, thereby driving the massage wheel 9 to rotate away from the user's back, and the massage punch 10 to rotate toward the user's back. During this process, the third rotating shaft 31 rotates in the positioning block 30.

[0032] Next, the user activates the gas rod 13, which causes the massage punch 10 to correspondingly penetrate the second massage hole 17, thereby impacting the cushion 8 to perform point massage on the user's back.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it.
