A second gear 7 is fixedly connected to the middle of the output shaft of each driving motor 9, and the outer wall of each second gear 7 is meshed with a transmission belt 8. The inner wall of the other end of each transmission belt 8 is meshed with another second gear 7, and the inner wall of the other second gear 7 is fixedly connected to the outer wall of the connecting rod 6. The upper and lower second gears 7 are transmitted through the transmission belt 8, and the two connecting rods 6 rotate on the inner wall of the concave bracket 3 through the second gear 7.

[0027] During operation, the turntable 2 is installed inside the mounting base 1, the concave bracket 3 is fixed on the top of the turntable 2, and the two connecting rods 6 are inserted into the concave bracket 3, so that the stage light body 5 is installed in the middle of the concave bracket 3. Then the mounting base 1 is moved to the designated installation position of the stage light and connected to the power supply, and the two driving motors 9 are controlled by the controller 4 to start at the same time, and the output shaft of the driving motor 9 is used to drive the second gear 7 to rotate, and the second gear 7 is used to drive the transmission belt 8 to rotate, and then the transmission belt 8 is used to make the upper and lower second gears 7 rotate synchronously, and then the top second gear 7 is fixedly connected to the connecting rod 6, so that the two connecting rods 6 can be driven to rotate inside the concave bracket 3, and then the upper and lower angles of the stage light body 5 can be adjusted and calibrated. The connection between the rectangular rod 10 and the output shaft of the driving motor 9 can prevent the bottom second gear 7 from shaking when rotating, thereby improving the stability and service life of the structure. Moreover, the turntable 2 can rotate inside the mounting base 1, so that the concave bracket 3 can rotate on the top of the mounting base 1, and the horizontal angle of the stage light body 5 can be adjusted and calibrated, so that the staff can quickly adjust the angle of the stage light, thereby improving the practicality of the stage light.

[0028] Further, such as Figure 2 As shown, a positioning rod 21 is fixedly connected to the top of the turntable 2, a bearing 25 is fixedly connected to the bottom of the positioning rod 21, and one side of the bearing 25 is fixedly connected to the inner wall of the mounting base 1. A servo motor 24 is fixedly connected to the inside of the mounting base 1, and a first gear 23 is fixedly connected to the middle of the output shaft of the servo motor 24.

[0029] During operation, the controller 4 can control the servo motor 24 to start, and the output shaft of the servo motor 24 can be used to drive the first gear 23 to rotate. The first gear 23 can drive the positioning rod 21 to rotate when the first gear 23 is engaged with the gear ring 22. The positioning rod 21 is fixedly connected to the turntable 2 so that the turntable 2 rotates inside the mounting base 1. The bearing 25 fixed to the bottom of the positioning rod 21 can reduce the friction effect between the positioning rod 21 and the inside of the mounting base 1, thereby improving the rotation efficiency of the positioning rod 21. The above method allows the staff to quickly adjust and calibrate the horizontal angle of the stage light body 5, which is convenient for the staff to operate and improves the practicality of the stage light.

[0030] Further, such as Figure 4 and Figure 5As shown, the inner walls at both ends of the top of the concave bracket 3 are fixedly connected with fixed blocks 11, and one end of each fixed block 11 is provided with two slide grooves 12, and the inside of each slide groove 12 is fixedly connected with a slide rod 13. The outer wall of each slide rod 13 is slidably connected with a slider 14, and each slider 14 is slidably connected with the inside of the slide groove 12 through the slide rod 13. One side of each two sliders 14 is fixedly connected with a movable block 15, and one side of each movable block 15 is fixedly connected with two electric push rods 17, and the other end of each electric push rod 17 is fixedly connected with the fixed block 11. The outside of each electric push rod 17 is sleeved with a spring 18, and the two ends of each spring 18 are fixedly connected with one side of the movable block 15 and the fixed block 11 respectively. Each movable block 15 slides with one side of the fixed block 11 through two electric push rods 17. A tooth groove 16 is provided on the top of each movable block 15, and one side of each tooth groove 16 is meshed and connected with the bottom outer wall of the second gear 7.

[0031] During operation, when the connecting rod 6 is driven to rotate by the driving motor 9, when the angle of the stage light body 5 is adjusted to an appropriate position, the driving motor 9 stops running so that the second gear 7 outside the connecting rod 6 stops rotating, and then the two electric push rods 17 fixed on one side of the top of the fixed block 11 are used to push the movable block 15 to move. By connecting the slider 14 and the slide rod 13, the movable block 15 drives the slider 14 to slide inside the slide groove 12 when moving, which can prevent the movable block 15 from being misplaced during the movement. And as the movable block 15 moves, the tooth groove 16 can be stuck at the bottom of the second gear 7, so that the stage light body 5 can be prevented from shaking or rotating after adjustment and calibration, and the light can be prevented from being offset, which can improve the effect of the stage light on the stage. When the stage light body 5 needs to be adjusted, the electric push rod 17 retracts when the driving motor 9 is started again, and the movable block 15 can be separated from the bottom of the second gear 7, so that the second gear 7 can rotate normally, and the elastic force of the spring 18 can be used to reduce the jamming of the movable block 15 when moving, thereby improving the service life and practicality of the structure.

[0032] Working principle: After the mounting base 1 is moved to the designated installation position of the stage light and connected to the power supply, when the angle of the stage light body 5 needs to be adjusted and calibrated, the controller 4 is used to control the electric push rod 17 to retract, so that the movable block 15 can be separated from the bottom of the second gear 7, so that the second gear 7 can rotate normally. Then the two driving motors 9 are started at the same time, and the output shaft of the driving motor 9 is used to drive the second gear 7 to rotate, and the second gear 7 is used to drive the transmission belt 8 to rotate. Then the transmission belt 8 is used to make the upper and lower second gears 7 rotate synchronously, which can drive the two connecting rods 6 to rotate inside the concave bracket 3, and then the upper and lower angles of the stage light body 5 can be adjusted and calibrated. When the driving motor 9 stops running, the two electric push rods 17 fixed on one side of the top of the fixed block 11 are used to push the movable block 15 to move. By connecting the slider 14 and the slide bar 13, the movable block 15 drives the slider 14 to slide inside the slide groove 12 when moving, which can prevent the movable block 15 from being misplaced during the movement. And as the movable block 15 moves, the tooth groove 16 can be stuck at the bottom of the second gear 7, which can prevent the stage light body 5 from shaking or rotating after adjustment and calibration, and prevent the light from shifting. Then, the controller 4 controls the servo motor 24 to start, and the output shaft of the servo motor 24 is used to drive the first gear 23 to rotate. The first gear 23 is engaged with the gear ring 22, so that the first gear 23 can drive the positioning rod 21 to rotate when rotating. The positioning rod 21 is fixedly connected to the turntable 2 to allow the turntable 2 to rotate inside the mounting base 1, and the bearing 25 can reduce the friction effect between the positioning rod 21 and the inside of the mounting base 1, so that the concave bracket 3 can rotate on the top of the mounting base 1, and the horizontal angle of the stage light body 5 can be adjusted and calibrated.
