[0034] The present invention is further described below through specific implementation methods.

[0035] See also Figures 1 to 6 A massage mechanism adjustment device includes a fixed member 10, a movable member 20, and a control assembly 30. The movable member 20 is movably connected to the fixed member 10 and can convert linear motion into circumferential rotation. The relative position of the two can be adjusted by linearly moving the movable member 20 relative to the fixed member 10. When the movable member 20 moves linearly relative to the fixed member 10, it can also produce circumferential rotation. The direction of linear movement corresponds to the direction of circumferential rotation. The specific direction can be adjusted according to actual conditions. For example, if the linear movement direction is upward, the direction of circumferential rotation is counterclockwise, and if the linear movement direction is downward, the direction of circumferential rotation is clockwise.

[0036] The control assembly 30 is provided with a transmission shaft 31 which is in transmission cooperation with the movable element 20. The control assembly 30 can be controlled to lock the transmission shaft 31 so that the movable element 20 is in one-way rotation and one-way linear movement, or the control assembly 30 can be controlled to release the transmission shaft 31 so that the movable element 20 is in two-way rotation in the circumferential direction. When the transmission shaft 31 is locked, it cannot rotate, and due to the cooperation between the two, the movable element 20 is in one-way rotation and one-way linear movement. The specific direction can be adjusted according to the actual situation, for example, the linear movement of the movable element 20 can only be downward, and the circumferential rotation of the movable element 20 can only be clockwise. When the transmission shaft 31 is released, the transmission shaft 31 can rotate, and due to the cooperation between the two, the movable element 20 is in two-way rotation and two-way linear movement, that is, the linear movement of the movable element 20 can be upward or downward, and the circumferential rotation of the movable element 20 can be counterclockwise or clockwise.

[0037] The transmission cooperation between the movable element 20 and the transmission shaft 31 can adopt gear transmission. The movable element 20 is provided with a first transmission element 21 at the cooperation end with the transmission shaft 31, and the transmission shaft 31 is correspondingly provided with a second transmission element 32, and the first transmission element 21 is engaged with the second transmission element 32. And set to: when the transmission shaft 31 is locked, the transmission shaft 31 remains fixed, the second transmission element 32 is in one-way rotation, and the first transmission element 21 is in one-way rotation; when the transmission shaft 31 is released, the transmission shaft 31 can rotate, the second transmission element 32 can rotate in two directions, and the first transmission element 21 can also rotate in two directions. Among them, the rotation shaft of the first transmission element 21 and the rotation shaft of the second transmission element 32 are perpendicular or parallel, which can adopt bevel gears, cylindrical gears, etc., and the bevel gears are taken as an example in the figure.

The end of the movable element 20 is also provided with a screw 23 which is fixed relative to the shell 40 to axially limit the movable element 20. The transmission shaft 31 is also sleeved with a positioning bearing 33 to radially position the transmission shaft 31.

[0039] In the embodiment, in order to realize the one-way rotation of the second transmission member 32, the control assembly 30 further comprises a one-way bearing 34 which is coaxially arranged in the second transmission member 32 and fixed in the circumferential direction of the second transmission member 32, and the transmission shaft 31 is fixedly arranged through the inner ring of the one-way bearing 34. When the inner ring of the one-way bearing 34 rotates relative to the outer ring in a certain direction, the resistance can be ignored, and when the inner ring rotates in the other direction, the resistance is very large. Under the condition that the external force does not exceed the maximum load, the inner and outer rings can only rotate in one direction. When the transmission shaft 31 remains fixed, the second transmission member 32 rotates in one direction due to the one-way bearing 34, and when the transmission shaft 31 rotates, the second transmission member 32 rotates in two directions.

The transmission shaft 31 passes through the inner ring and cooperates with the inner ring profile, that is, the transmission shaft 31 is fixed in the circumferential direction with the inner ring to keep synchronous rotation. When the electromagnetic clutch 35 is powered off, the inner ring can rotate relative to the outer ring, and the resistance can be ignored; when the electromagnetic clutch 35 is powered on, the inner ring and the outer ring are subjected to resistance, and under the condition that the resistance does not exceed the maximum load, the inner ring and the outer ring cannot rotate relative to each other.

[0042] In the embodiment, the fixed part 10 and the movable part 20 are realized by a lead screw and a nut, that is, the fixed part 10 is provided with a threaded hole, and the movable part 20 is realized by a lead screw which is arranged through the threaded hole. The housing 40 is realized by an integrated housing 40 or a split structure, and the split structure is taken as an example in the figure, which comprises a first shell 41 and a second shell 42 which are fixed by screws.

When movable part 20 is two-way linear motion, second massage subassembly 60 can linearly move in the direction away from or close to first massage subassembly 50.
