The transmission rod 43 can also drive the two rollers 44 to rotate. The rotation of the rollers 44 can make the two ropes 45 move in opposite directions, and the rope 45 at one end contracts and the rope 45 at the other end extends, thereby making the rope 45 pull the placement rack 1, so that the placement rack 1 moves around the axis of the rotating shaft to produce an angle change, so that the placement rack 1 will drive the lamp body 3 to change the angle, thereby realizing the angle adjustment operation of the lamp body 3. Through automatic adjustment, there is no need to disassemble the lamp body 3, which improves the convenience of angle adjustment of the lamp body 3.

[0025] Example 2

[0026] Reference Figure 1 and 2 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0027] In this embodiment, the bottom of the connection box 41 is fixedly connected to the bottom of the inner cavity of the mounting frame 2 , one end of the rope 45 is fixedly connected to the roller 44 , and the other end of the rope 45 is fixedly connected to the bottom of the placement frame 1 .

[0028] Both sides of the bottom of the inner cavity of the mounting frame 2 are provided with mounting grooves 21, and the inner cavity of the mounting grooves 21 is movably connected with screws, and the end of the transmission rod 43 away from the servo motor 42 is movably connected to the inner cavity of the connection box 41 through a bearing.

[0029] Limiting wheels 451 are provided at the front and rear ends of the inner cavity of the connecting box 41. Both sides of the limiting wheel 451 are movably connected to the limiting plate 452 through bearings, and the bottom of the limiting plate 452 is fixedly connected to the bottom of the inner cavity of the connecting box 41.
