The second limiting block 4051 rotates with the second driven wheel 405 within the second interval area between the first limiting post 11 and the second limiting post 12 to be adapted to limit the rotation angle of the second driven wheel 405. A first eccentric rotating shaft is provided on the first driven wheel 404, and the other end of the first connecting member 406 is rotatably connected to the first eccentric rotating shaft to be adapted to drive the first connecting slider 401 to slide along the length direction of the guide member 408; a second eccentric rotating shaft is provided on the second driven wheel 405, and the other end of the second connecting member 407 is connected to the second eccentric rotating shaft to be adapted to drive the second connecting slider 402 to slide along the length direction of the guide member 408.
[0050] Specifically, the output end of the driving component is in transmission connection with the driving wheel 403. The driving wheel 403 is in gear engagement with the first driven wheel 404 and the second driven wheel 405. The driving wheel 403 rotates to drive the first driven wheel 404 and the second driven wheel 405 to rotate. The first driven wheel 404 drives the first connecting slider 401 to slide along the length direction of the guiding member 408 through the first connecting member 406, and the second driven wheel 405 drives the second connecting slider 402 to slide along the length direction of the guiding member 408 through the second connecting member 407. A first eccentric rotating shaft is provided on the first driven wheel 404, and a second eccentric rotating shaft is provided on the second driven wheel 405. One end of the first connecting member 406 is rotatably connected to the first connecting slider 401, and the other end of the first connecting member 406 is rotatably connected to the first eccentric rotating shaft; one end of the second connecting member 407 is rotatably connected to the second connecting slider 402, and the other end of the second connecting member 407 is rotatably connected to the second eccentric rotating shaft. In the state of spacing adjustment, the driving component drives the driving wheel 403 to rotate, the driving wheel 403 drives the first driven wheel 404 and the second driven wheel 405 to rotate, and the first connecting member 406 and the second connecting member 407 perform eccentric motions to push the first connecting slider 401 and the second connecting slider 402 to slide relatively or away from each other along the length direction of the guiding member 408.
[0051] It can be understood that a first limiting post 11 and a second limiting post 12 are provided on the housing 1. The first limiting post 11 and the second limiting post 12 are arranged at intervals. In the circular track formed by the diameters of the first limiting post 11 and the second limiting post 12, the first arc segment and the second arc segment are included with the first limiting post 11 and the second limiting post 12 as the demarcation points, where the first arc segment is the first interval region and the second arc segment is the second interval region.
[0052] A first limiting block 4041 is provided on the first driven wheel 404. When the first driven wheel 404 rotates, the first limiting block 4041 rotates within the first interval region along with the first driven wheel 404, thereby restricting the rotation amplitude of the first driven wheel 404 to further control the sliding stroke of the first connecting slider 401, and thus controlling the adjustment stroke of the first massage component 2; similarly, a second limiting block 4051 is provided on the second driven wheel 405. When the second driven wheel 405 rotates, the second limiting block 4051 rotates within the second interval region along with the second driven wheel 405, thereby restricting the rotation amplitude of the second driven wheel 405 to further control the sliding stroke of the second connecting slider 402, and thus controlling the adjustment stroke of the second massage component 3.
[0053] It can be understood that when the module numbers of the first driven wheel 404 and the second driven wheel 405 are the same, the adjustment amplitudes of the driving wheel 403 for the first massage component 2 and the second massage component 3 are the same. When the module numbers of the first driven wheel 404 and the second driven wheel 405 are set in proportion, the adjustment strokes of the first massage component 2 and the second massage component 3 are set in proportion.
[0054] It should be noted that a cover plate is provided above the transmission assembly to ensure the reliable operation of the transmission assembly, avoid the influence of dust on the transmission assembly, improve reliability, and extend the service life.
[0055] Refer to Figure 4 As shown, in some embodiments of the present invention, the drive assembly includes a support member 411 and a second drive member. The support member 411 is fixedly connected to the housing 1. The second drive member is disposed on the support member 411. The second drive member is in transmission connection with the driving wheel 403, and the second drive member drives the driving wheel 403 to rotate.
[0056] Specifically, the support member 411 provides an installation basis for the second drive member. The support member 411 is fixedly connected to the housing 1. In the state of distance adjustment, the second drive member drives the driving wheel 403 to rotate, so as to adjust the sliding stroke of the connecting slider, and further adjust the distance between the two massage head assemblies.
[0057] Refer to Figure 4 As shown, in some embodiments of the present invention, an installation groove 15 is formed at the bottom of the housing 1. A limit tooth 151 is provided at the bottom of the installation groove 15. The drive assembly further includes a chuck 410 and an elastic member 409. A limit gear 4101 that cooperates with the limit tooth 151 is provided on one side of the chuck 410 facing the bottom of the installation groove 15. The drive assembly further includes an elastic member 409. One end of the elastic member 409 abuts against the bottom of the installation groove 15, and the other end of the elastic member 409 abuts against the chuck 410. The limit gear 4101 can cooperate with the limit tooth 151 or under the elastic force of the elastic member 409, the limit gear 4101 can disengage from the limit tooth 151. In the state where the limit gear 4101 is disengaged from the limit tooth 151, the second drive member can drive the chuck 410 to rotate so as to drive the driving wheel 403 to rotate.
[0058] Specifically, the support member 411, the chuck 410, and the second driving member are all disposed in the installation groove 15. A limiting card slot is provided at the bottom of the installation groove 15. A limiting gear 4101 that cooperates with the limiting card slot is provided on one side of the chuck 410 facing the bottom of the installation groove 15. An elastic member 409 is provided between the chuck 410 and the bottom of the installation groove 15. Specifically, the elastic member 409 is a spring. One end of the elastic member 409 abuts against the bottom of the installation groove 15, and the other end of the elastic member 409 abuts against the chuck 410. In the state of spacing adjustment, when the elastic force of the elastic member 409 causes the limiting gear 4101 of the chuck 410 to disengage from the limiting teeth 151, the second driving member can drive the chuck 410 to rotate, so as to drive the driving wheel 403 to rotate, and further drive the first driven wheel 404 and the second driven wheel 405 to rotate. The first connecting member 406 pushes the first connecting slider 401 to slide, and the second connecting member 407 pushes the second connecting slider 402 to slide, so as to realize the spacing adjustment of the first massage assembly 2 and the second massage assembly 3. In the massage state, the elastic member 409 causes the limiting gear 4101 and the limiting teeth 151 to mesh with each other, realizing the locking of the chuck 410, so as to prevent the first massage assembly 2 and the second massage assembly 3 from changing the spacing during the massage process.
[0059] It can be understood that the state change of the elastic member 409 can be adjusted manually or by electric control.
[0060] In some embodiments of the present invention, the second driving member includes a knob 412 rotatably disposed on the support member 411, and a handle 413 rotatably disposed on the knob 412. The knob 412 is in transmission connection with the chuck 410. An arc-shaped convex platform 4131 is provided on one side of the handle 413 facing the chuck 410, and a flat convex platform 4102 is provided on one side of the chuck 410 facing the knob 412. The handle 413 has a buckling state in which the arc-shaped convex platform 4131 abuts against the flat convex platform 4102, and a flipped-up state in which the arc-shaped convex platform 4131 is disengaged from the flat convex platform 4102; in the buckling state, the limiting gear 4101 and the limiting teeth 151 are locked and cooperated; in the flipped-up state, the limiting gear 4101 and the limiting teeth 151 are disengaged from each other, and the handle 413 is adapted to drive the knob 412 to rotate, so as to drive the chuck 410 to rotate.
[0061] Specifically, when the spacing is adjusted manually, the second driving member includes a knob 412 rotatably connected to the support member 411, and a handle 413 rotatably provided on the knob 412. An arc-shaped boss 4131 is provided on the side of the handle 413 facing the chuck 410, and a flat boss 4102 is provided on the side of the chuck 410 facing the knob 412. In the state of spacing adjustment, the handle 413 is in the flipped-up state, so that the arc-shaped boss 4131 is separated from the flat boss 4102. At this time, under the elastic force of the elastic member 409, the elastic member 409 returns to its original length to drive the side of the chuck 410 facing the knob 412 to move, so that the limit gear 4101 of the chuck 410 is separated from the limit tooth 151. By selecting the knob 412 with the handle 413, the chuck 410 is driven to rotate, and thus the spacing between the two massage head assemblies is adjusted. In the massage state, the handle 413 is in the buckled state. At this time, the arc-shaped boss 4131 and the flat boss 4102 are in mutual abutting and extrusion, so that the chuck 410 presses the elastic member 409, and the limit gear 4101 and the limit tooth 151 are engaged with each other. At this time, the chuck 410 is in a self-locking state. This self-locking structure is simple and can ensure the stability of the structure in the massage state.
[0062] Referring to Figure 3 As shown, in some embodiments of the present invention, the first massage assembly 2 further includes a first eccentric wheel 23, a first axis cam 24, a first fixed cover 25, a first shaft sleeve 26, and a first end cover 27 that are sequentially sleeved on the transmission shaft 5.

The first shaft sleeve 26 is fixed to the first connecting slider 401, and the first end cover 27 is fixedly connected to the first fixed cover 25 to be suitable for clamping the first shaft sleeve 26;
[0063] The second massage assembly 3 further includes a second eccentric wheel 33, a second axis cam 34, a second fixed cover 35, a second shaft sleeve 36, and a second end cover 37 that are sequentially sleeved on the transmission shaft 5.

The second shaft sleeve 36 is fixed to the second connecting slider 402, and the second end cover 37 is fixedly connected to the second fixed cover 35 to be suitable for clamping the second shaft sleeve 36.
[0064] Specifically, the first bushing 26 is sleeved on the first eccentric wheel 23, the first axial cam 24 and the first fixed cover 25. The outer periphery of the first bushing 26 is fixedly connected to the first connecting slider 401. When the first connecting slider 401 slides axially along the transmission shaft 5, the first massage assembly 2 is driven to slide. The first massage member 21 is sleeved on the first eccentric wheel 23. The transmission shaft 5 rotates to drive the first eccentric wheel 23 to rotate, so as to drive the first massage member 21 to swing. The first axial cam 24 and the first eccentric wheel 23 fix the first massage member 21, so that the first massage member 21 is relatively fixed to the first eccentric wheel 23 and the first axial cam 24, avoiding the first massage member 21 sliding along the direction of the transmission shaft 5 during the massage process. The second massage member 22 is sleeved on the first axial cam 24, and the second massage member 22 swings along the length direction of the transmission shaft 5 on the axial cam. It can be understood that the first end cover 27 is connected to the first fixed cover 25 to be suitable for clamping the first bushing 26.
[0065] Similarly, the second bushing 36 is sleeved on the second eccentric wheel 33, the second axial cam 34 and the second fixed cover 35. The outer periphery of the second bushing 36 is fixedly connected to the second connecting slider 402. When the second connecting slider 402 slides axially along the transmission shaft 5, the second massage assembly 3 is driven to slide. The third massage member 31 is sleeved on the second eccentric wheel 33. The transmission shaft 5 rotates to drive the second eccentric wheel 33 to rotate, so as to drive the third massage member 31 to swing. The second axial cam 34 and the second eccentric wheel 33 fix the third massage member 31, so that the third massage member 31 is relatively fixed to the second eccentric wheel 33 and the second axial cam 34, avoiding the third massage member 31 sliding along the direction of the transmission shaft 5 during the massage process. The fourth massage member 32 is sleeved on the second axial cam 34, and the fourth massage member 32 swings along the length direction of the transmission shaft 5 on the second axial cam 34. It can be understood that the second end cover 37 is connected to the second fixed cover 35 to be suitable for clamping the second bushing 36.
