In this embodiment, the face ring is made of metal or plastic. The face ring has a conventional structure in the prior art. In actual use, a circular hole is provided on the outer wall of the face ring, within which a spring, a marble 5, and a retaining ring are located. The marble, under the action of the spring, extends outward from the outer surface of the face ring. During installation, the marble engages the inner wall of the mounting hole to achieve positioning, improving installation convenience.

[0028] During actual application, a vertical adjustment groove 6 is provided on the symmetrical side wall of the cylindrical adjustment seat; at the same time, during actual application, a circular support 7 is provided in the cylindrical adjustment seat, and a screw 8 is provided on the circular support, and the screw passes through the vertical adjustment groove, and the circular support is raised and lowered in the cylindrical adjustment seat and is locked and positioned by the screw; in this embodiment, the circular support can be raised and lowered in the cylindrical adjustment seat and positioned by the screw, which improves the convenience of use and the stability and reliability of use.

[0029] Furthermore, in this embodiment, the end of the lamp body is rotatably connected to a support rod 9 via a pin, the top of which is fixed to the bottom surface of the circular support. The support rod connects the lamp body to the circular support, and when the lamp body is inside the cylindrical adjustment seat, the support rod and the lamp body are aligned. When the lamp body is outside the cylindrical adjustment seat, the lamp body and the support rod rotate around the pin and can be adjusted in angle to meet different usage requirements.
