The mounting base 1 is rotatably connected to the first rotating shaft 8. One end of the first rotating shaft 8 passes through one side of the mounting base 1 and is fixedly connected to the second arc-shaped connecting frame 3. The rotation of the first rotating shaft 8 moves the second arc-shaped connecting frame 3. The mounting base 1 is rotatably connected to a connecting rod 11.

A second helical gear 10 is fixedly connected to the outer side of the first rotating shaft 8. The rotation of the second helical gear 10 causes the first rotating shaft 8 to rotate. One side of the second helical gear 10 meshes with the first helical gear 9. The rotation of the first helical gear 9 causes the second helical gear 10 to rotate. A first pulley 12 is fixedly connected to the end of the connecting rod 11 away from the first helical gear 9. The rotation of the first pulley 12 causes the connecting rod 11 to rotate. The mounting base 1 is rotatably connected to a hollow rod 16, and a second rotating rod 15 is rotatably connected to the hollow rod 16. One end of the second rotating rod 15 passes through one side of the mounting base 1 and is fixedly connected to the first arc-shaped connecting frame 2. The rotation of the second rotating rod 15 causes the first arc-shaped connecting frame 2 to rotate. A second pulley 13 is fixedly connected to the outside of the hollow rod 16. The rotation of the hollow rod 16 causes the second pulley 13 to rotate. The second pulley 13 is connected to the first pulley 12 through a transmission belt 14.

[0025] Furthermore, a support frame 21 is fixedly connected to one side of the mounting base 1, and a motor 20 is fixedly connected to one side of the support frame 21, so as to better install and fix the motor 20.

[0026] Furthermore, a fixed column 25 is rotatably connected to the side of the support frame 21 away from the motor 20. One end of the fixed column 25 is fixedly connected to the output end of the motor 20. When I rotate, the fixed column 25 rotates.

A spring 26 is fixedly connected between one side of the second fixed plate 19 and the support frame 21. The second fixed plate 19 moves towards the spring 26 to compress the spring 26. The spring 26 generates elastic force under compression. When the spring 26 loses its compressive force, the spring 26 and the second fixed plate 19 return to their original positions.

[0032] When adjusting the angle of the lamp head body 4 during use, the motor 20 is turned on. The motor 20 rotates the fixing column 25, which in turn rotates the fourth vertical tooth 28 along with the connecting column 7.

The electric telescopic rod 17 moves the first vertical tooth 22 through the first fixing plate 18. The first vertical tooth 22 gradually approaches the second vertical tooth 23, pushing the second vertical tooth 23, causing the second fixing plate 19 to move away from the fourth vertical tooth 28 along with the third vertical tooth 27. 2. The second vertical tooth 23 meshes together, and the motor 20 is turned on. The motor 20 drives the second fixed plate 19 to rotate through the fixed column 25.

The first vertical tooth 22 drives the hollow rod 16 to rotate through the first fixed plate 18. The hollow rod 16 drives the second pulley 13 to rotate. The second pulley 13 drives the first pulley 12 to rotate through the transmission belt 14. The first pulley 12 drives the first helical gear 9 to rotate through the connecting rod 11. The first helical gear 9 drives the first rotating shaft 8 to rotate through the second helical gear 10. The rotation of the first rotating shaft 8 drives the second arc-shaped connecting frame 3 to rotate. The second arc-shaped connecting frame 3 moves the lamp head body 4 inside the first arc-shaped connecting frame 2 and the circular connecting seat 5, adjusting the angle of the lamp head body 4 in another direction.
