[0016] In order to make the purpose, technical scheme and advantage of the utility model more clear and obvious, the following specific implementation case shown in the drawing is used to describe the utility model. However, it should be understood that these descriptions are only exemplary and not to limit the scope of the utility model. In addition, in the following description, the description of the known structure and technology is omitted to avoid unnecessary confusion of the concept of the utility model.

[0017] Here, it also needs to be explained that, in order to avoid the utility model from being obscured by unnecessary details, only the structure and / or processing steps closely related to the scheme according to the utility model are shown in the drawing, and other details not closely related to the utility model are omitted.

[0018] Reference Figs. 1-3 The specific implementation adopts the following technical scheme: including: lamp shell, base, elastic support assembly, lamp cap, the inner side of the lamp shell is provided with an inner cylinder, the lamp shell is fixedly connected with the base, the center of the base is provided with a mounting cavity, the elastic support assembly includes a shell, a movable seat and a compression spring, the shell is fixedly connected with the mounting cavity, the movable seat is movably arranged at the bottom of the shell, the movable seat can move up and down along the shaft in the shell, and the displacement range is limited by the cooperation of the step of the inner wall of the shell and the flange of the outer periphery of the movable seat, so as to realize limited displacement. The bottom of the movable seat is provided with a spherical groove, the compression spring is arranged in the shell, one end of the compression spring abuts against the mounting cavity, and the other end of the compression spring abuts against the movable seat, so as to provide downward elastic force and provide elastic support force for the movable seat. One end of the lamp cap is provided with a spherical convex, the spherical convex and the spherical groove are locally in surface contact and are in sliding fit, by rotating the lamp cap, cooperating with the elastic support of the compression spring, the spherical convex can rotate freely in the spherical groove, and the lamp cap can be adjusted at any angle.
