[0044] The adjustable pressing mechanism of the embodiment works as follows. First, the user can rotate the second screw rod 28 by the knob 29 according to the need of the waist and back massage. The second screw rod 28 is threadedly connected with the square rod 26, and thus drives the square sliding sleeve 25 to slide relative to the square rod 26. The square sliding sleeve 25 is driven by the fourth lug 7d to flip the edge block 7 around the first shaft 8 through the cooperation of the second pin 27 and the limiting sliding groove 7e and the gravity of the edge block 7, so as to flip the edge blocks 7 on the left and right sides of the middle block 3 upward and adjust the flipping angle of the edge blocks 7 relative to the middle block 3, so that the middle block 3 and the two edge blocks 7 form a concave structure. Then, the user lies in the concave structure, and the front of the waist and back is in contact with the first massage assembly on the middle block 3, and the sides of the waist and back are in contact with the second massage assemblies on the two edge blocks 7. Then, the first power assembly is controlled to drive the first massage assembly to massage the front of the user's waist and back, and the second power assembly is controlled to drive the second massage assembly to massage the sides of the user's waist and back. At the same time, the first screw rod 5 is controlled to reciprocate, and thus drives the middle block 3 to reciprocate on the first sliding rod 4 in the front-back direction, and thus reciprocate along the length of the human body to comprehensively massage the user's waist and back, greatly improving the user's massage experience.

[0045] When the first power assembly works, the first motor 13 drives the second shaft 12 to rotate, the second shaft 12 drives the worm sleeve 10 to rotate, the worm sleeve 10 drives the worm wheel 9 to rotate when rotating, on one hand, the worm wheel 9 drives the track groove on it to rotate, and on the other hand, the second power assembly works, specifically: the worm wheel 9 drives the first shaft 11 to rotate, the first shaft 11 drives the third bevel gear 18 to rotate, the third bevel gear 18 drives the second bevel gear 17 to rotate, the second bevel gear 17 drives the first bevel gear 16 to rotate, the first bevel gear 16 drives the third shaft 15 to rotate, the third shaft 15 drives the rotating disc 14 to rotate, and thus the rotating disc 14 drives the track groove to rotate synchronously. When the track groove rotates, the first pin 24 drives the rotating ring 21 to reciprocate up and down, and the rotating ring 21 drives the rotating block 19 to reciprocate up and down due to the limiting of the convex edge 19a and the screw sleeve 22. When the rotating block 19 reciprocates up and down, on one hand, the rotating block 19 drives the massage ball 23 to reciprocate up and down through the convex edge 19a and the third lug 19b, and on the other hand, the rotating block 19 reciprocates and rotates under the action of the transmission screw 20, and thus the massage ball 23 rotates while reciprocating up and down through the convex edge 19a and the third lug 19b, increasing the diversity of the massage and thus enriching the user's massage experience.

[0046] In addition, when the track groove driven by the worm wheel 9 rotates, the track groove cooperates with the third pin 31 to drive the slide plate 30 to reciprocate up and down, and when the slide plate 30 reciprocates up and down, the convex 30a cooperates with the square rod 26 to drive the edge block 7 to reciprocate around the first shaft 8 to form vibration, thereby further increasing the massage diversity and enriching the massage experience of the user.

[0047] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
