Meanwhile, in the embodiment, when the first transmission wheel 820 rotates in a direction, the first one-way bearing 510 is in a loaded state and can drive the first rotating shaft 200 to rotate. When the first transmission wheel 820 rotates in the other direction, the first one-way bearing 510 is in an unloaded state, at which time it cannot drive the first rotating shaft 200 to rotate. Further, in the embodiment, the first one-way bearing 510 can adopt other structures of overrunning clutches, such as ratchet overrunning clutches, etc.

[0074] In an embodiment, referring to Figure 4 Further, in the embodiment, the first transmission part 810 and the first transmission wheel 820 can be configured as transmission gears, at which time the transmission connection between the first transmission part 810 and the first transmission wheel 820 can be gear transmission, synchronous belt transmission, chain wheel transmission, etc. Meanwhile, in the embodiment, the transmission ratio during transmission can be adjusted to achieve the purpose of transmission deceleration (torque increase) or acceleration (torque decrease) according to the number of teeth during transmission by the transmission gears. Meanwhile, in the embodiment, when the first transmission wheel 820 rotates in a direction, the first one-way bearing 510 is in a loaded state and can drive the first rotating shaft 200 to rotate. When the first transmission wheel 820 rotates in the other direction, the first one-way bearing 510 is in an unloaded state, at which time it cannot drive the first rotating shaft 200 to rotate. Further, in the embodiment, the first one-way bearing 510 can adopt other structures of overrunning clutches, such as ratchet overrunning clutches, etc. Figure 4), the power transmission between the first transmission part 810 and the second transmission wheel 920 can be completed by a transmission gear, the power output of the second transmission structure 800 is changed by the transmission gear, that is, the rotating speed generated when the driving shaft 600 rotates is reduced after being transmitted through the first variable speed transmission wheel 830 and the second variable speed transmission wheel 840, so that the rotating speed transmitted to the first transmission wheel 820 is reduced, so that the activity frequency of the massage arm meets the demand of massage. It should be noted that the second variable speed transmission wheel 840 is not connected with the first rotating shaft 200, specifically, the second variable speed transmission wheel 840 is arranged in the massager through a mounting shaft (see Figure 4 ), wherein the mounting shaft is arranged close to the first rotating shaft 200, and such arrangement can effectively utilize the space size and avoid the increase of the movement core.

[0075] Further, referring to Figure 4 , the third transmission structure 900 includes a second transmission part 910 and a second transmission wheel 920 in transmission connection, the switching structure 500 further includes a second one-way bearing 520, the second transmission part 910 is connected with the driving shaft 600 through the second one-way bearing 520, and the second transmission wheel 920 is drivingly connected with the second rotating shaft 400. Further, in the embodiment, the second transmission part 910 and the second transmission wheel 920 can be configured as transmission gears, at this time, the transmission connection between the second transmission part 910 and the second transmission wheel 920 can be gear transmission, synchronous belt transmission, chain wheel transmission, etc., and at the same time, in the embodiment, the transmission ratio during transmission can be adjusted according to the number of teeth during transmission by the transmission gear to achieve the purpose of transmission speed reduction (torque increase) or speed increase (torque reduction). At the same time, in the embodiment, when the second transmission wheel 920 rotates in one direction, the second one-way bearing 520 is in a loaded state and can drive the second rotating shaft 400 to rotate. When the second transmission wheel 920 rotates in the other direction, the second one-way bearing 520 is in an unloaded state, at this time, the second rotating shaft 400 cannot be driven to rotate. Further, in the embodiment, the first one-way bearing 510 can adopt other structures of overrunning clutches, such as ratchet overrunning clutches, etc. At the same time, in the embodiment, when the second transmission structure 800 adopts the above structure, when the driving shaft 600 rotates in one direction, only one one-way bearing is in a loaded state, and the other one-way bearing is in an unloaded state, when the driving shaft 600 rotates in one direction and switches to rotate in the other direction, the one-way bearing in the loaded state can be switched to the unloaded state, and the one-way bearing in the unloaded state can be switched to the loaded state.

[0076] However, the design is not limited to this, and in other embodiments, the second transmission part 910 is drivingly connected with the driving shaft 600, and the second transmission wheel 920 is connected with the second rotating shaft 400 through the second one-way bearing 520.

In this case, when the worm part is integrally formed with the driving shaft 600, the first transmission part 810 is not connected to the driving shaft 600 through a one-way bearing. However, the design is not limited thereto, and in other embodiments, the driving shaft 600 can be provided with a worm, and in this case, the first transmission part 810 is configured as a worm.
