The support block 201 is fixedly connected to one side of the shell 1, the electric push rod 202 is hinged to one side of the support block 201, the rotating block 203 is hinged to one side of the electric push rod 202, the rotating block 203 is rotatably connected to one side of the shell 1, the support frame 204 is fixedly connected to one side of the rotating block 203, and the cushion 205 is fused to the top of the support frame 204.

[0032] Specifically, Figure 4 As shown, the fixing assembly 3 includes a support plate 301, a motor 302, a gear 303, a bidirectional screw rod 304, a guide shaft 305 and a fixing block 306. The support plate 301 is fixedly connected to one side of the support frame 204, the motor 302 is bolted to one side of the support plate 301, the gear 303 is fixedly connected to the output end of the motor 302, a plurality of bidirectional screw rods 304 are fixedly connected to one side of the gear 303, the guide shaft 305 is fixedly connected to one side of the support plate 301, a plurality of fixing blocks 306 are threadedly connected to the outer wall of the plurality of bidirectional screw rods 304, and a plurality of fixing blocks 306 are slidably connected to the outer wall of the guide shaft 305.

[0033] Specifically, Figure 5 As shown, the limit assembly 4 includes a sliding groove 401, a sliding block 402 and a limit block 403. The multiple sliding grooves 401 are all opened inside the shell 1, the multiple sliding blocks 402 are respectively slidably connected to the inside of the multiple sliding grooves 401, and the multiple limit blocks 403 are respectively fixedly connected to the top of the multiple sliding blocks 402.

[0034] During use, the patient's shoulders can lie on the shell 1, and then the head can be placed on the support frame 204. The cushion 205 can provide protection for the back of the patient's head and increase comfort. When the angle of the patient's head needs to be adjusted, the electric push rod 202 can be started to rotate the rotating block 203, thereby driving the support frame 204 to rotate. When the support frame 204 rotates, the angle of the patient's head can be adjusted. When the patient's neck needs to be fixed, the motor 302 can be started to drive the gear 303 to drive the bidirectional screw rod 304 to rotate. Since the fixing block 306 is threadedly connected to both ends of the bidirectional screw rod 304, when the bidirectional screw rod 304 rotates, the fixing block 306 will move inward or outward at the same time, and the guide shaft 305 can guide the moving direction of the fixing block 306 to avoid deviation. The sliding block 402 and the limit block 403 can slide in the sliding groove 401 to limit the patient's shoulder.

[0035] Specifically, Figure 2 As shown, the reinforcement assembly 5 includes a fixing plate 501 and a supporting plate 502 , wherein the fixing plate 501 is fixedly connected to one side of the shell 1 , and the supporting plate 502 is fixedly connected to one side of the shell 1 .

[0040] During use, the fixing plate 501 can increase the strength of the shell 1, the support plate 502 can provide support for the patient's back to avoid hanging, the support column 6 and the anti-slip pad 7 can be used together to provide support for the shell 1, increase the friction at its bottom, and avoid displacement of the shell 1 during use. The groove 8 can match the spine of the human back to avoid oppression thereon, and the friction pad 9 can increase the friction between the patient's back and the shell 1 and improve comfort.

[0041] By adopting the above technical solution, the problem of an existing cervical and lumbar traction device that, during use, when the patient lies down, the angle of his head cannot be adjusted, which causes discomfort in the patient's cervical spine, and the back of the patient's head cannot be protected, thereby further improving the patient's comfort is solved.

[0042] Working principle: When the present application is in use, the patient's shoulders can lie on the shell 1, and then the head can be placed on the support frame 204. The soft cushion 205 can provide protection for the back of the patient's head and increase comfort. The fixing plate 501 can increase the strength of the shell 1. The support plate 502 can provide support for the patient's back to avoid hanging. The support column 6 is used in conjunction with the anti-slip pad 7 to provide support for the shell 1 and increase the friction at its bottom to avoid displacement of the shell 1 during use. The groove 8 can match the spine of the human back to avoid oppression thereon, and the friction pad 9 can increase the friction between the patient's back and the shell 1 and improve comfort. When the angle of the patient's head needs to be adjusted When the support frame 204 rotates, the angle of the patient's head can be adjusted. When the patient's neck needs to be fixed, the motor 302 can be started to make the gear 303 drive the bidirectional screw rod 304 to rotate. Since the fixing block 306 is threadedly connected to both ends of the bidirectional screw rod 304, when the bidirectional screw rod 304 rotates, the fixing block 306 will move inward or outward at the same time, and the guide shaft 305 can guide the moving direction of the fixing block 306 to avoid deviation. The sliding block 402 and the limit block 403 can slide in the sliding groove 401 to limit the patient's shoulder.
