[0041] The lamp 2 is fixed to the external device through the mounting frame 1. When the rotating frame 12 is fixed to the external device, the fixing frame 11 and the lamp 2 fixed thereto rotate with the rotating bolt 31 as the rotating axis to change the illumination angle of the lamp 2. Specifically, when the angle of the lamp 2 needs to be adjusted, the rotating bolt 31 and the adjusting bolt 32 are first loosened, the lamp 2 is rotated to the required angle, the adjusting bolt 32 moves from the first position to the second position in the arc-shaped movable groove 121, and then the rotating bolt 31 and the adjusting bolt 32 are fixed, and the illumination angle of the lamp 2 can be adjusted.

[0047] Furthermore, the rotation angle of the lamp 2 relative to the mounting frame 1 is ≤160°. Figure 4 As shown, the rotation range of the lamp 2 of the present solution is controlled above the second connecting arm 112, and the specific rotation angle is within 160°, which can adapt to a variety of different illumination angles.

[0048] Of course, in other embodiments, when the mounting frame 1 is set to other structures, the rotation of the lamp 2 can be extended to below the height of the mounting frame 1, that is, the rotation angle can be increased to more than 160°.

[0049] Further, the fixed hook 4 includes a main hook 41 and an auxiliary hook 42, the main hook 41 is connected to the mounting frame 1, and the auxiliary hook 42 is hinged on the main hook 41, so that the inner wall of the main hook 41 and the inner wall of the auxiliary hook 42 form a clamping space 43;

[0050] The fixed hook 4 further includes an adjusting component 44 , and the adjusting component 44 is used to drive the auxiliary hook 42 to move so as to adjust the size of the clamping space 43 .

[0051] The fixed hook 4 is located below the mounting frame 1. The mounting frame 1 is bolted to the external device. The fixed hook 4 is clamped to the external device. The double fixation makes the installation of the lamp 2 more secure. The fixed hook 4 of this solution forms a clamping space 43 through the cooperation of the main hook 41 and the auxiliary hook 42. The external device is clamped in the clamping space 43. The fixed hook 4 is also provided with an adjustment component 44. The adjustment component 44 can adjust the opening size of the clamping space 43 to adapt to the clamping and fixing of external devices of different volumes.

[0052] Further, the auxiliary hook 42 includes a first connecting section 421 and a second connecting section 422. The end of the first connecting section 421 extends obliquely to one side to form the second connecting section 422. The first connecting section 421 is provided with a first through slot 4211. The main hook 41 is provided with a second through slot 413. The second connecting section 422 passes through the second through slot 413 and extends into the main hook 41, so that the inner wall of the second connecting section 422 and the inner wall of the main hook 41 form the clamping space 43.

[0053] The adjustment assembly 44 includes an adjustment piece 441 and a screw rod 442, the adjustment piece 441 is threadedly connected to the screw rod 442, the main hook 41 is provided with a first inflection point 411 and a second inflection point 412, the first inflection point 411 is located above the second inflection point 412, one end of the screw rod 442 passes through the first through slot 4211 and is hinged to the first inflection point 411 of the main hook 41, one side of the first connecting section 421 abuts against the adjustment piece 441, and the connection between the first connecting section 421 and the second connecting section 422 is hinged to the second inflection point 412 of the main hook 41, so that: when the adjustment piece 441 on the screw rod 442 is turned, the first connecting section 421 is driven to move, and at the same time, the second connecting section 422 rotates along the second inflection point 412 to adjust the size of the clamping space 43.

[0054] The auxiliary hook 42 of this embodiment is a special-shaped structure, the first connecting section 421 of the auxiliary hook 42 is connected to the adjustment assembly 44, and the second connecting section 422 of the auxiliary hook 42 and the lower half of the main hook 41 form a clamping space 43 of approximately "C" shape. Generally, the first connecting section 421 is located outside the main hook 41, and (the first connecting section 421 and) the second connecting section 422 can rotate along the second inflection point 412, and because the main hook 41 is provided with a second through slot 413, the second connecting section 422 will not be interfered by the main hook 41 when rotating. When the size of the clamping space 43 needs to be adjusted, the adjusting member 441 on the screw rod 442 is turned forward, and the adjusting member 441 moves inward to drive the first connecting section 421 to move forward, and at this time, the second connecting section 422 rotates inward, and the clamping space 43 becomes smaller; on the contrary, the adjusting member 441 on the screw rod 442 is turned in the reverse direction, and the clamping space 43 becomes larger.

[0055] The main hook 41 and the auxiliary hook 42 are all rigidly connected, and can ensure the long-term stability of the connection after being clamped on the external device. The main hook 41 and the auxiliary hook 42 have simple structures, and the user can easily adjust the size of the clamping space 43 to adapt to the fixation of external devices of different sizes.

[0056] Furthermore, a plurality of anti-slip strips 45 are provided on the inner wall of the main hook 41 and / or the inner wall of the auxiliary hook 42 .

[0057] Since the main hook 41 and the auxiliary hook 42 are clamped on the external device, a plurality of anti-slip strips 45 are provided on the inner wall of the main hook 41 and / or the auxiliary hook 42 (the second connecting section 422), which can further ensure the stability of the fixed hook 4 after being clamped on the external device to prevent it from coming out.

[0058] Furthermore, the upper end of the fixed hook 4 is connected to the mounting frame 1 by bolts. Since the fixed hook 4 (main hook 41) of the present solution is connected to the lower part of the mounting frame 1 by bolts, the upper and lower heights of the fixed hook 4 can be slightly adjusted by bolts, so that the fixed hook 4 can be better fixed to the external device. At the same time, the fixed hook 4 is also easy to disassemble, which is convenient for maintenance and replacement.

[0059] On the other hand, the present invention also provides a lamp 2, using any of the above-mentioned rotatable lamp brackets. The lamp 2 has the above-mentioned beneficial effects of the rotatable lamp bracket, which will not be described in detail here.
