After the adjustment is completed, the staff rotates Turn the screw 17, so that the screw 17 pushes the fixing seat 16 to fit tightly with the surface of the sphere 13. At this time, the rotation of the sphere 13 will drive the fixing seat 16 to move. When the fixing seat 16 moves too much, the fixing seat 16 contacts the side wall of the cavity, which plays a limiting role. The elastic member 15 is used to push the fixing seat 16 to reset. The fixing seat 16 and the sphere 13 fit relatively fixed, and then can synchronously drive the sphere 13 to reset, thereby completing its reset. Relying on this setting, the spherical joint can rotate a certain amount with the patient's breathing, and the range of its rotation can be limited. The elastic member 15 enables the sphere 13 to automatically follow and reset when the patient exhales, thereby fixing the spherical joint firmly and causing the irradiation end to squeeze the patient's skin.

[0024] Further, such as Figure 4 As shown, an oil filling tube 21 is fixedly connected to the connecting seat 11; a sealing cavity is opened in the middle of the oil filling tube 21; a spring is fixedly connected to the inner wall of the sealing cavity; a sealing ball 22 is fixedly connected to the end of the spring; when in use, the spherical joint of the polarized light therapy device needs to move to a certain extent following the human body's breathing, and a patient needs to adjust to irradiate different positions for treatment, and the sphere 13 needs to move frequently. When in use, the staff can insert a syringe into the oil filling tube 21. The insertion of the end of the syringe will lift the sealing ball 22, so that the oil filling tube 21 is connected to the inside of the ball seat 12, so that lubricating oil is injected into the inside of the ball seat 12 through the syringe, and the lubricating oil is filled in the inside of the ball seat 12, so that the spherical movement can be lubricated to reduce friction and wear. When the syringe is pulled out, the sphere 13 seals the oil filling tube 21 under the action of the spring.

[0025] Further, such as Figure 2-3As shown, a sealing groove is provided on the side of the ball seat 12 away from the connecting seat 11; the cross-section of the sealing groove is stepped; a plurality of sealing rings 32 are provided in the sealing groove; a rubber ring 31 is provided between the ball seat 12 and the connecting seat 11; when in use, the plurality of sealing rings 32 fit with the surface of the sphere 13, thereby sealing the ball seat 12 and the sphere 13, thereby reducing the outflow of lubricating oil from the hole between the ball seat 12 and the ball rod 14, and by providing the rubber ring 31, the connection between the ball seat 12 and the connecting seat 11 can be sealed, thereby improving the sealing effect of the connection.
