The arc surface of the driving rod 412 is threadedly connected to a moving frame 413. The surface of the moving frame 413 slides through the surface of the mounting plate 3. The bottom end of the movable frame 413 is in contact with the surface of the irradiator 5, and fixing grooves 419 are provided on both sides of the bottom end of the movable frame 413. A rotating column 418 is rotatably connected to the upper surface of the irradiator 5 corresponding to the position of the fixing groove 419. The arc surface of one side of the rotating column 418 is snapped with the inner wall of the fixing groove 419. Springs 416 are fixedly connected to both sides of the bottom surface of the movable frame 413, and a positioning plate 415 is fixedly connected to the upper end of the spring 416. A positioning groove 4181 is provided on the upper surface of the fixing column. The cross-section of the positioning groove 4181 is a regular hexagon. The inner wall of the positioning groove 4181 is snapped with the bottom surface of the positioning plate 415. A protective shell 414 is fixedly connected to the upper surface of the mounting plate 3 corresponding to the position of the servo motor 411. The cross-sectional size of the protective shell 414 is adapted to the cross-sectional size of the servo motor 411. A telescopic rod 417 is slidably connected to the inner wall of the spring 416. The two ends of the telescopic rod 417 are respectively snapped with the fixed The positioning plate 415 is fixedly connected to the surface of the movable frame 413, the bottom cross-section of the rotating column 418 is semicircular, the rotating column 418 is a hard alloy column, the protective component 42 includes two positioning frames 421, the two positioning frames 421 are fixedly connected to the two side surfaces of the irradiator 5 respectively, one side of the positioning frame 421 is threaded with an auxiliary shaft 424, the arc surface of the auxiliary shaft 424 is wrapped with a cover cloth 422, one end surface of the auxiliary shaft 424 is fixedly connected with an extrusion frame 425, the upper surface of the extrusion frame 425 is threaded with an extrusion rod 426, the bottom end surface of the extrusion rod 426 is rotatably connected with an extrusion plate 427, the end of the cover cloth 422 away from the positioning frame 421 is fixedly connected with a protective belt 423, the protective belt 423 is a sandbag, the bottom end of the protective belt 423 is arc-shaped, the cover cloth 422 includes a black cloth piece and a red cloth piece, the black cloth piece is located on the outside of the cover cloth 422, and the red cloth piece is located on the inside of the cover cloth 422.

[0027] When in use, in order to facilitate the lifting and lowering of the position of the irradiator 5, the servo motor 411 is started to drive the driving rod 412 on the surface of the mounting plate 3 to rotate, and then the driving rod 412 drives the movable frame 413 on the surface of the irradiator 5 to lift / move, so that the position of the entire irradiator 5 can be adjusted; in order to facilitate the replacement of the entire irradiator 5, the fixing grooves 419 opened on both sides of the bottom end of the movable frame 413 and the rotating column 418 on the surface of the irradiator 5 are used for rotational clamping and limiting, and then the positioning plate 415 is clamped and fixed with the positioning groove 4181 opened on the upper surface of the rotating column 418.

At the same time, the shielding cloth 422 wrapped around the two ends of the irradiator 5 is used to block the two irradiators to prevent the irradiation light from superimposing on each other and causing excessive light intensity to damage the skin.

[0028] This solution has three clever points: first, the protective belt 423 with sand is used to stick to the skin, so that the shielding cloth 422 can completely block the irradiation light emitted by the irradiator 5 from radiating outward; second, the shielding cloth 422 is arranged between two irradiators 5 arranged side by side to prevent the irradiation light emitted by the two irradiators 5 from being superimposed on each other and causing excessive intensity to damage the skin; third, two shielding cloths 422 on the same irradiator 5 can form a barrier area, which can form a relatively closed irradiation space for the target area to be irradiated, so that the irradiation light affects the operator and damages the intact skin around it.
