The sliding sleeve block 34 is fixed on the output end of the double-head electric cylinder 35, and the sliding sleeve block 34 is slidingly connected with the drive rod 36.

[0038] The drive roller 16 and the massage contact roller 15 perform the back and hip massage action, and support position adjustment to adapt to different body sizes. The double-head electric cylinder 35 drives the sliding sleeve block 34 to slide on the drive rod 36, adjusts the position of the drive cam 33, and changes the transverse position of the massage contact roller 15.

[0039] The drive cam 33 is provided with the massage contact roller 15. The front end of the massage contact roller 15 is provided with a massage contact head 32. The bottom of the massage contact roller 15 is provided with a cam limiting block 31. The cam limiting block 31 rotates in cooperation with the drive cam 33. The massage contact roller 15 slides relative to the sliding ventilation groove 4. The size of the cam limiting block 31 is greater than that of the sliding ventilation groove 4.

[0040] The cam limiting block 31 ensures that it does not come off the groove body. At the same time, the massage contact head 32 directly contacts the patient's skin and transmits the massage force.

[0041] The neck elastic assembly 10 includes a clamping sleeve block 22, a spring mounting block 30 mounted on the clamping sleeve block 22, and a telescopic spring rod 27 arranged on both sides of the spring mounting block 30. The spring mounting block 30 is provided with a concave sliding groove 29 on both sides. The clamping sleeve block 22 includes a sliding stroke block 24. The sliding stroke block 24 is provided with a contact block 23 and a clamping connecting block 25 on both sides, respectively.

[0042] The convex sliding block 28 is slidingly matched with the concave sliding groove 29. The clamping connecting block 25 is provided with a clamping sleeve 26 on both sides. The telescopic spring rod 27 is connected with the spring mounting block 30 and the clamping sleeve 26 at both ends, respectively.

[0043] The neck elastic assembly 10 buffers the neck pressure and realizes multidirectional sliding to adapt to different body shapes and lesion positions. The spring mounting block 30 and the telescopic spring rod 27 absorb the neck pressure through the telescopic spring rod, preventing the massage head from excessively pressing the neck. The clamping sleeve block 22 and the sliding stroke block 24 are clamped together. The clamping sleeve block 22 is matched with the concave sliding groove 29 of the spring mounting block 30 through the convex sliding block 28, allowing the neck massage head 5 to slide at multiple angles at the rear of the seat 3, adapting to the movement of the patient's neck, and the contact block 23 and the clamping connection block 25 limit structure ensure that the clamping sleeve block 22 stably slides in the sliding groove of the seat 3, avoiding dislocation;

[0044] The patient steps on the pedal to drive the transmission system, and the leg is lifted to optimize the neck fit, forming a composite effect of "active movement-passive massage", and the double-head electric cylinder 35 adjusts the position of the massage contact roller 15. The neck elastic assembly 10 adapts to different neck shapes to ensure treatment accuracy. In view of the "neck-back-hip-leg" linkage pathological mechanism, the treatment effect is improved through multi-site massage to restore the mechanical balance of the spine;

[0045] Common neck pain is mostly caused by long-term lack of exercise or related symptoms caused by long-term work. The relevance is that common neck pain is often caused by related symptoms of the back spine, hips and legs. This case takes ankylosing spondylitis patient as an example to illustrate the operation principle of the device;

[0046] When the device is working, the pedal mounting rod 17 can rotate relative to the seat 3, so as to adjust the angle of the pedal assembly 6 relative to the seat 3 according to the body shape and the focus position of the patient's lesion, so that the patient's lesion position can better contact the massage contact roller 15, and at the same time, the patient's leg is lifted, which can make the patient's neck better contact the neck massage head 5;

[0047] When the patient's neck contacts the neck massage head 5, it will push the neck massage head 5 to press the spring mounting block 30 backward. The spring mounting block 30 and the clamping sleeve block 22 are matched and slid through the convex sliding groove sliding block, and the elastic telescopic rod is expanded to partially absorb the extrusion force of the patient's neck, preventing the neck massage head 5 from causing excessive pressure on the patient's neck. When the patient's neck shakes, the elastic telescopic rod releases the elastic force, which can make the neck massage head 5 better fit the patient's neck and improve the massage effect;

[0048] The engaging sleeve block 22 is engaged with the rear part of the seat 3, and the size of the engaging sleeve block 22 is smaller than the matching sliding groove of the rear part of the seat 3, but due to the limiting effect of the contact block 23 and the engaging connecting block 25, the engaging sleeve block 22 can be multi-angle slid relative to the rear part of the seat 3 to a certain extent, so that after the patient's neck is attached to the neck massage head 5, the patient's neck can drive the neck massage head 5 to move through the activity of the patient's neck, and through the stress of different angles, the passive massage of the patient's neck can be realized, wherein the neck massage head 5 can be replaced by different models to adapt to the needs of patient body type and lesion location difference;

[0049] After the patient sits on the seat 3, the patient steps on the foot pedal to drive the foot pedal gear 13 to rotate, and then drives the transmission connecting rod 18 to rotate through the foot pedal tooth chain 14, and drives the driving roller 16 on the hip and back to rotate through the transmission tooth 20 wheel and the transmission tooth 20 chain on one side, thereby driving the driving cam 33 to rotate, and driving the massage contact roller 15 to reciprocate to massage the relevant acupoints of the patient;

[0050] When it is necessary to adjust the position of the massage contact block 23, the double-head electric cylinder 35 is started to drive the sliding sleeve block 34 on both ends to slide on the driving rod 36, thereby driving the driving cam 33 to adjust the position on the driving rod 36, and due to the clamping effect of the cam limiting block, the position of the massage contact roller 15 will also be adjusted and slid in the sliding ventilation groove 4 when the position of the driving cam 33 is adjusted;

[0051] The device can realize the active movement of the patient's legs, thereby driving the transmission mechanism 2 to massage the relevant acupoints of the patient's legs and back, and due to the angle limitation of the foot pedal mounting rod 17, the patient's neck can be attached to the neck massage head 5, and under the limiting of the neck elastic assembly 10, the neck massage head 5 can be closely attached to the patient's neck, and when the patient steps on the foot pedal 12, the body will sway, thereby the neck drives the neck massage head 5 to sway, and due to the limiting effect of the engaging sleeve block 22, the neck massage head 5 can passively massage the patient's neck when the patient's body reaches a certain degree of sway, wherein the sliding ventilation groove 4 can better ventilate while supporting the movement of the massage contact roller 15, and help the moving patient to dissipate heat.
