[0024] The fixing mechanism 8 includes a pull wire 81, a fixing pin 82, a spring 83 and a gear 84. The gear 84 is installed on the rotating sleeve 52. The fixing pin 82 that cooperates with the gear 84 is installed on the top surface of the mounting seat 3 through the spring 83. Two pull wires 81 respectively connected to the two pull rods 4 are installed on the fixing pin 82.

[0025] The two elastic bands 1 are connected together by the lock buckle 2 and the buckle 21. The mounting seat 3 is fixed to the user's head through the connected elastic bands 1. The connection method of the elastic bands 1 is convenient for the user to connect and separate the two elastic bands 1. The rotating seat 5 is rotatably mounted on the mounting seat 3 through the rotating sleeve 52. The fixing mechanism 8 installed on the rotating sleeve 52 can fix the rotating sleeve 52, ensuring the stability of the rotating seat 5 during use. Two fixing mechanisms 8 are installed on the rotating sleeve 52 to ensure the working effect of the fixing mechanism 8. When the user pulls the pull rod 4, the fixing mechanism 8 on the rotating sleeve 52 is released. In addition, when the pull rod 4 is in a stationary state, the fixing block 41 and the fixing groove 42 are separated. When the user pulls the pull rod 4, the fixing block 41 enters the fixing groove 42, and the rotating sleeve 52 and the pull rod 4 are connected together through the cooperation of the fixing block 41 and the fixing groove 42. When the user rotates the pull rod 4, the rotating sleeve 52 rotates together with the pull rod 4. At this time, the user can adjust the angle of the lighting lamp 6. The lighting lamp 6 is installed on the rotating seat 5 through the cooperation of the side wall groove and the dovetail tenon 51. The installation method of the lighting lamp 6 is convenient for the user to install and remove the lighting lamp 6. The shape of the dovetail tenon 51 ensures the stability of the lighting lamp 6 installed on the rotating seat 5.

[0026] The gear 84 is installed on the rotating sleeve 52, and the rotating sleeve 52 is fixed by the cooperation of the fixing pin 82 and the gear 84, which ensures the stability of the rotating seat 5 and the lighting lamp 6 during the use of the device. The user can release the fixing pin 82 from the gear 84 by moving the fixing pin 82. The fixing pin 82 is installed on the top surface of the mounting seat 3 by a spring 83, which ensures that the fixing pin 82 can quickly return to its original position after moving, thereby ensuring the working effect of the fixing pin 82. The fixing pin 82 is provided with a pull wire 81 connected to two pull rods 4. When the user pulls the pull rod 4, the two fixing pins 82 are both pulled by the pull wire 81, which ensures that when the user pulls one pull rod 4, the fixing of the two fixing pins 82 to the gear 84 is released, so that the user can adjust the inclination angle of the lighting lamp 6 with one hand.

[0027] Specifically, symmetrical guide rollers 7 are installed on the top surface of the mounting seat 3 , and the pull wire 81 is installed on the pull rod 4 after passing around the guide rollers 7 .

[0028] The guide roller 7 can change the movement trajectory of the pull wire 81, thereby preventing the pull wire 81 from contacting the edge of the mounting base 3 during movement, reducing the wear on the pull wire 81 during movement, and extending the service life of the pull wire 81. The side wall of the guide roller 7 is in an arc shape, which ensures the stability of the pull wire 81 during movement.

[0029] Specifically, the pull rod 4 and the rotating sleeve 52 are connected via a spring 43 .

[0030] When the user releases the pull rod 4, the pull rod 4 returns to its original position under the action of a spring 43, thereby ensuring the working effect of the pull rod 4. The spring 43 also reduces the force required for the fixing pin 82 to return to its original position, thereby ensuring the working effect of the fixing mechanism 8. The pull rod 4 is connected to the rotating sleeve 52 through a spring 43. When the rotating sleeve 52 rotates, the pull rod 4 will rotate together with the rotating sleeve 52 under the action of the spring 43, thereby ensuring that the cooperation between the fixing block 41 and the fixing groove 42 will not be affected by the rotation of the rotating sleeve 52.

[0031] Specifically, a protrusion is provided on the side wall of the opening of the fixing groove 42 away from the fixing block 41 .

[0032] The side wall protrusion of the fixing groove 42 can block the fixing block 41, ensuring that the moving distance of the pull rod 4 will not be too long, reducing the amount of deformation of the spring 43, and extending the service life of the spring 43. The position of the side wall protrusion of the fixing groove 42 ensures that the cooperation between the fixing block 41 and the fixing groove 42 will not be hindered.

[0033] Specifically, the depth of the side wall groove of the rotating seat 5 for mounting the dovetail tenon 51 is smaller than the height of the rotating seat 5 , and the side wall groove of the rotating seat 5 passes through the top surface of the rotating seat 5 .

[0034] The height of the groove of the dovetail tenon 51 installed on the rotating seat 5 ensures the stability of the lighting lamp 6 after being installed on the rotating seat 5. The position of the groove of the dovetail tenon 51 on the rotating seat 5 is convenient for the user to install the lighting lamp 6 on the rotating seat 5.

[0035] Specifically, an arc-shaped groove 31 is formed on the side wall of the mounting seat 3 , and the edge of the arc-shaped groove 31 is in the shape of an arc.

[0036] The arc groove 31 increases the contact area between the mounting base 3 and the user's head, ensuring the stability of the mounting base 3 after being fixed on the user's head. The shape of the side wall edge of the arc groove 31 reduces damage to the user's skin and improves the user's comfort.

[0037] Specifically, an isolation pad 32 is installed on the side wall of the arc-shaped groove 31 .

[0038] The isolation pad 32 can prevent the mounting base 3 from directly contacting the patient's skin, reduce the pressure on the user's skin during use of the device, and improve the user's comfort. The isolation pad 32 can also absorb the sweat generated by the user during use of the device, ensuring the stability of the device during use.

[0039] The working principle and use process of the utility model are as follows: the lighting lamp 6 is installed on the rotating seat 5 through the cooperation of the side wall groove and the dovetail tenon 51, the two elastic bands 1 are connected together by the lock buckle 2 and the buckle 21, and the mounting seat 3 is fixed to the user's head through the elastic band 1. When adjusting the inclination angle of the lighting lamp 6, pull a pull rod 4. When the pull rod 4 moves, the fixed block 41 enters the fixed groove 42. As the fixed block 41 moves, the fixed pin 82 is pulled up by the pull wire 81, and the fixation of the fixed pin 82 to the gear 84 is released. The user rotates the pull rod 4, and the rotating sleeve 52 is rotated by the pull rod 4 under the cooperation of the fixed block 41 and the fixed groove 42 to achieve the adjustment of the inclination angle of the lighting lamp 6. After the inclination angle of the lighting lamp 6 is adjusted, the pull rod 4 is moved back to its original position, and the fixed pin 82 returns to its original position under the action of the spring 2 83. The gear 84 is fixed by the fixed pin 82, and the lighting lamp 6 is fixed at this time.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
