The intervertebral disc supports, connects and cushions the lumbar spine and is located near the spinal cord. Trauma and degeneration lead to imbalance of the internal and external mechanical balance of the lumbar spine, resulting in kyphosis or rupture of the annulus fibrosus and prolapse of the nucleus pulposus, i.e., lumbar disc herniation. If the lumbar disc herniation compresses the spinal nerves or cauda equina, it will cause low back pain and even paralysis. Traction devices are one of the means to treat lumbar disc herniation.

[0031] When used specifically: fill the water tank 31 with water, separate the mother Velcro strap 1 22 and the child Velcro strap 1 23, the mother Velcro strap 2 25 and the child Velcro strap 2 26, align the waist fixing plate 1 with the waist, place the arc plate 1 21 and the mother Velcro strap 1 22 on both sides of the body, tie the mother Velcro strap 1 22 and the child Velcro strap 1 23, the mother Velcro strap 2 25 and the child Velcro strap 2 26 to the body and stick them together, start the water pump 32, the water pump 32 drives the water flow from the water outlet pipe 3 39 into the hydraulic chamber 37, the liquid in the hydraulic chamber 37 gradually increases and the pressure rises, thereby driving the hydraulic rod 38 to move upward The top of the hydraulic rod 38 contacts the transmission block 36. The hydraulic rod 38 drives the transmission block 36 and then drives the limit block 213 to move upward during the upward movement, thereby achieving the traction effect on the lumbar vertebrae. When the pressure in the hydraulic chamber 37 increases to a preset threshold, that is, reaches a preset traction force, the pressure generated in the hydraulic chamber 37 drives the slider 315 to move upward, and the slider 315 no longer blocks the water outlet pipe 33. The water flow can flow back to the water tank 31 through the water outlet pipe 33 to ensure that the pressure in the hydraulic chamber 37 does not continue to increase, thereby avoiding damage to the body. The magnitude of the traction force can be adjusted by rotating the adjusting knob 316. By rotating the adjusting knob 316, the adjusting knob 316 drives the worm 310 to rotate, and then drives the worm wheel 311 to rotate. The rotation of the worm wheel 311 drives the transmission rod 312 to rotate. The rotation of the transmission rod 312 drives the threaded sleeve 313 to move, so that the spring 314 is deformed to change its elastic force. The force applied by the spring 314 to the slider 315 is adjusted, thereby changing the maximum pressure in the hydraulic chamber 37, that is, adjusting the maximum traction force of the device. If the user feels uncomfortable due to excessive traction during the traction of the device, the user can pull open the emergency baffle 35 so that the emergency baffle 35 no longer blocks the second water outlet pipe 34, and the water can flow back to the water tank 31 through the second water outlet pipe 34, so that the pressure in the hydraulic chamber 37 drops rapidly, preventing the device from causing damage to the human body; Initially, the solenoid valve 1 43 is opened to allow water to flow through, and the solenoid valve 2 44 is closed to prevent water from flowing through. The water flows into the water inlet pipe 1 45 and enters the rubber massage bag 1 47. The rubber massage bag 1 47 expands to massage the waist. The pressure in the water inlet pipe 1 45 gradually increases. When the rubber massage bag 1 47 expands to a certain size, the water flow will drive the slider 2 414 to move. The movement of the slider 2 414 triggers the micro switch 415. The micro switch 415 controls the solenoid valve 1 43 to close and the solenoid valve 2 44 to open. The water flows to the rubber massage bag 2 48, the pressure in the water inlet pipe 1 45 decreases, the slider 2 414 is reset, the rubber massage bag 2 48 expands, and the waist is massaged. The pressure in the water inlet pipe 2 46 gradually increases. When the rubber massage bag 2 48 expands to a certain size, the water flow drives the slider 2 414 to move and trigger the micro switch 415. The micro switch 415 controls the electromagnetic valve 1 43 to open and the electromagnetic valve 2 44 to close. After that, the device will repeat the above process in a cycle to make the water in the water tank 31 circulate. The massage force can be adjusted by rotating the second adjusting knob 416. By rotating the second adjusting knob 416, the second adjusting knob 416 drives the second worm 49 to rotate, and then drives the second worm wheel 410 to rotate. The rotation of the second worm wheel 410 drives the second transmission column 411 to rotate. The rotation of the second transmission column 411 will drive the second threaded sleeve 412 to move, so that the second spring 413 is deformed, thereby changing the elastic force thereof. The force applied by the second spring 413 to the second slider 414 is adjusted, thereby changing the maximum pressure in the first water inlet pipe 45 and the second water inlet pipe 46, that is, adjusting the maximum massage force of the device. When the device is finished using, pour out the water in the water tank 31, then move the locking rod 29 to disengage it from the locking ring 210, unlock the traction bracket 28, rotate the traction bracket 28 so that its upper part contacts the limit block 213, pull the traction bracket 28 to disengage the limit block 213 from the groove of the slide slot 216, so that the traction bracket 28 can slide relative to the limit block 213, slide the traction bracket 28 to move the limit block 213 to another groove, press the traction bracket 28 to insert the limit block 213 into the groove to fix the position of the traction bracket 28, and then rotate the upper folding piece 211 to complete the overall folding of the device.

[0032] In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creatively designing without departing from the purpose of the invention, they should all fall within the scope of protection of the invention.
