When in use, the head is covered in the stretching head cover 21, and the stretching bracket 22 is driven to rise by the stretching telescopic rod 24. The stretching bracket 22 drives the stretching chain 23 to rise, so that the stretching chain 23 drives the stretching head cover 21 to rise, and the stretching head cover 21 drives the head to rise, thereby traction and stretching the cervical spine.

[0035] A massage mechanism 3 is provided below the stretching head cover 21. The massage mechanism 3 includes a lifting plate 31. The lifting plate 31 is slidably mounted on the back of the frame 1 and is lifted and lowered by a massage telescopic rod 32. A massage box 33 is provided on the front of the lifting plate 31. Two rotating plates 34 are provided on the upper end of the massage box 33. Roller assemblies 35 are rotatably mounted on the front of the two rotating plates 34. The roller assemblies 35 are controlled to turn by a steering motor 36. A first bidirectional screw rod 37 is rotatably mounted inside the massage box 33, and the first bidirectional screw rod 37 is driven to rotate by a first screw motor 38. The first bidirectional screw rod 37 is connected to a first bidirectional nut 39 through a bidirectional thread. A spur rack 310 is fixedly connected to one side of the first bidirectional nut 39. The two rotating plates 34 One end is closer, and the other end is farther away, and its shape is an eight-shaped shape. The closer side of the two rotating plates 34 is provided with a rotating shaft 311, and the rotating plate 34 is rotatably installed on the upper end of the massage box 33 through the rotating shaft 311. The lower end of the rotating shaft 311 is provided with a first gear 312, and the first gear 312 is meshed and connected with the spur rack 310; a round rack 313 is fixedly connected to the front of the lifting plate 31, and a second gear 314 is provided in the middle of the first bidirectional screw rod 37. The round rack 313 passes through the back of the massage box 33 and is meshed and connected with the second gear 314. Two support guide pillars 315 are provided on the back of the massage box 33, and the two support guide pillars 315 are slidably connected with the lifting plate 31. The bottom of the massage box 33 is provided with a bottom cover 316 for sealing the massage box 33;

[0036] The roller assembly 35 includes a roller group 351, a roller shaft 352 and a roller bracket 353. The roller group 351 is composed of multiple rollers, and a number of protrusions are evenly distributed on the outer diameter surface of each roller. The roller group 351 is rotatably connected to the roller shaft 352. The roller shaft 352 is installed on the inner side of the roller bracket 353 through a buffer mechanism 354. The roller bracket 353 is controlled to rotate by a steering motor 36.

[0037] Among them, the cervical vertebra needs to wait for a few minutes after traction and stretching to improve the rehabilitation training effect. During this time, massaging the cervical vertebra through the massage mechanism 3 can further improve the rehabilitation training effect, and the combination of traction and stretching and massage can also save time. The massage mechanism 3 has two massage modes. Mode 1, the roller group 351 is in a horizontal state, and the cervical vertebra is massaged up and down; Mode 2, the roller group 351 is in a vertical state, and the cervical vertebra is massaged front and back. After the up and down massage is completed, the roller assembly 35 is driven by the steering motor 36 to rotate 90 degrees to switch the roller group 351 in the horizontal state to the vertical state, and then the cervical vertebra is massaged front and back;

[0038] Mode 1: The roller group 351 is in a horizontal state, and the two roller groups 351 fit the neck at a suitable angle. The massage telescopic rod 32 drives the lifting plate 31 to reciprocate up and down on the frame 1, so that the massage box 33 reciprocates up and down, and the roller group 351 reciprocates up and down, so that the roller group 351 moves up and down while rolling the neck, and the cervical vertebra can be massaged in the up and down directions;

[0039] Method 2: The roller group 351 is in a vertical state, and the two roller groups 351 are in contact with the neck. The first two-way screw 37 is driven to rotate by the first screw motor 38. The first screw motor 38 rotates forward and reversely to make the first two-way nut 39 approach or move away from each other, so that the two spur racks 310 fixedly connected to the first two-way nut 39 approach or move away from each other, so that the two first gears 312 rotate simultaneously, and the rotation directions are opposite, so that the two rotating shafts 311 rotate simultaneously, and the rotation directions are opposite, so that the angles of the two rotating plates 34 become larger or smaller, so that the two roller groups 351 approach or move away from each other. At the same time, the first screw motor 38 rotates forward and reversely to make the second gear 314 rotate forward and reversely. Since the round rack 313 is fixedly connected to the massage box 33 On, the round rack 313 is meshed with the second gear 314, so that the second gear 314 reciprocates on the round rack 313, so that the roller assembly 35 can move forward and backward, and the roller group 351 moves forward and backward, so that the roller group 351 can reciprocate back and forth while approaching or moving away from each other. Therefore, when the two roller groups 351 are located at the rear side of the cervical vertebrae, the two roller groups 351 are close to each other. When the two roller groups 351 move forward from the rear side, the two rotating plates 34 are opened to both sides at the same time, so that the two roller groups 351 roll from the rear side of the cervical vertebrae to the sides of the cervical vertebrae, so that the two roller groups 351 massage the cervical vertebrae at the same time, and the cervical vertebrae can be massaged back and forth by switching the first screw motor 38 forward and backward.

[0040] The buffer mechanism 354 includes two sliders 3541 arranged at both ends of the roller shaft 352, and two slide grooves 3542 matching the sliders 3541 are provided on both sides of the roller bracket 353. The slider 3541 is slidably installed in the slide groove 3542, and a spring 3543 is provided in the slide groove 3542. One end of the spring 3543 abuts against the bottom of the slide groove 3542, and the other end abuts against the slider 3541.

[0041] Among them, the buffer mechanism 354 is used to ensure a certain buffer distance between the roller group 351 and the neck, which can prevent the roller group 351 from excessively squeezing the neck. When the roller group 351 presses the cervical vertebra, the slider 3541 slides in the slide groove 3542 and squeezes the spring 3543 to compress it, and the spring 3543 can neutralize the pressing force.

[0042] A seat plate 41 is provided near the bottom of the frame 1 for sliding movement. The seat plate 41 is lifted and lowered by a lifting mechanism 4. The lifting mechanism 4 includes a second bidirectional screw rod 42 rotatably installed below the seat plate 41. The second bidirectional screw rod 42 is driven to rotate by a second screw motor 43. The second bidirectional screw rod 42 is connected to a second bidirectional nut 44 through a bidirectional thread. Connecting columns 45 are provided on both sides of the second bidirectional nut 44. The connecting columns 45 are rotatably connected to a connecting plate 46. Two connecting blocks 47 matching the connecting plate 46 are provided at the lower end of the seat plate 41. The connecting blocks 47 are rotatably connected to the other end of the connecting plate 46.

[0043] Two baffles 5 for limiting shoulders are arranged on the front of the frame 1 , one end of the baffle 5 extends forward and bends downward, a backrest 6 is arranged above the seat plate 41 , and the backrest 6 is fixedly mounted on the frame 1 .

[0044] When doing rehabilitation training, the rehabilitator sits on the seat board 41, and the height of the seat board 41 can be adjusted by the lifting mechanism 4, so that it can be suitable for rehabilitators of different heights. The second two-way screw 42 is driven to rotate by the second screw motor 43, so that the second two-way nuts 44 are close to or away from each other, thereby driving the seat board 41 to rise or fall on the front of the frame 1 through the two connecting plates 46. When the lower ends of the second two-way nuts 44 are close to each other, the seat board 41 rises, and when the lower ends of the second two-way nuts 44 are away from each other, the seat board 41 falls. By raising the seat board 41, the shoulders of the rehabilitator can contact the lower end of the baffle 5, which can restrict the human body and keep the body in a certain posture during traction, stretching and massage.

[0045] The stretching telescopic rod 24, the massage telescopic rod 32, the steering motor 36, the first screw motor 38, and the second screw motor 43 are all controlled and operated by the control box 7. The control box 7 adjusts its position through the universal adjustment mechanism 8. A display screen 72 and an operation panel 73 are provided on the front of the control box 7, and the display screen 72 is located above the operation panel 73. Handles 71 for pulling the control box 7 to move are provided on both sides of the control box 7.

[0046] The universal adjustment mechanism 8 includes a fixed rod 81, a first rotating arm 82, a second rotating arm 83, a universal ball base 84 and a universal ball 85. The fixed rod 81 is fixedly installed on one side of the frame 1. One end of the first rotating arm 82 is rotatably installed on the upper end of the fixed rod 81 through a rotating shaft, and the other end is rotatably connected to the second rotating arm 83 through a rotating shaft. A universal ball base 84 is provided on one side of the second rotating arm 83. The universal ball 85 is located inside the universal ball base 84, and the universal ball 85 is fixedly connected to the back of the control box 7 through a ball rod.

[0047] Among them, the control box 7 is used to control all rehabilitation training work. The parameters and actions of traction, stretching and massage can be set and controlled through the operation panel 73, and the operation panel 73 is provided with an emergency stop button to prevent excessive stretching or massage from causing discomfort to the patient. The display screen 72 can display the status of stretching and massage in real time, so that the user can understand the operating status of the device and his own rehabilitation process in real time. The universal adjustment mechanism 8 can move it to a position that is easy to operate. After the rehabilitation training is completed, the control box 7 can be folded to one side of the frame 1 through the first rotating arm 82 and the second rotating arm 83. During rehabilitation training, the control box 7 can be pulled in front by pulling the handle 71, and then the control box 7 can be adjusted to multiple angles through the universal ball 85.

[0048] The working principle and use process of the present invention:

[0049] When doing rehabilitation training, first sit on the seat board 1, with the back against the backrest 6, and pull the control box 7 in front of the rehabilitator through the universal adjustment mechanism 8, and perform subsequent rehabilitation training movements by operating the control box 7, and raise the seat board 41 through the lifting mechanism 4, so that the upper end of the shoulder of the rehabilitator contacts the lower end of the baffle 5, which can limit the human body and prevent the human body from moving excessively during traction, stretching and massage, and then put the head in the stretching head cover 21, and stretch the cervical vertebra through the traction and stretching mechanism 2. After the traction and stretching of the cervical vertebra, it is necessary to wait for a few minutes to improve the rehabilitation training effect. During this time, massaging the cervical vertebra through the massage mechanism 3 can further improve the rehabilitation training effect. The massage mechanism 3 has two massage modes. In mode one, the roller group 351 is in a horizontal state, and the cervical vertebra is massaged up and down; in mode two, the roller group 351 is in a vertical state, and the cervical vertebra is massaged front and back. After the up and down massage is completed, the steering motor 36 drives the roller assembly 35 to rotate 90 degrees to switch the roller group 351 in the horizontal state to the vertical state, and then the cervical vertebra is massaged front and back. After the traction, stretching and massage are completed, all mechanisms can be returned to their original positions.
