In this embodiment, the mounting base is a conventional structure of the prior art, mainly used to be fixed at positions such as the ceiling or the mounting beam, and the lamp body is also a conventional structure of the prior art, only simply applied, and its main shaft is a metal structure.

[0029] During actual application, a circular through-hole 4 is provided on the mounting base, and several V-shaped elastic pieces 5 are provided on the inner wall of the mounting base. One end of the V-shaped elastic piece is integrally formed on the inner wall of the mounting base, and the other end of the V-shaped elastic piece extends above the circular through-hole; at the same time, a convex ring 6 is integrally formed at the top end of the main shaft, and a positioning ring groove 7 is provided on the bottom surface of the convex ring; during assembly, the main shaft is inserted through the circular through-hole, the convex ring is located directly above the circular through-hole, and the end of the V-shaped elastic piece is snapped into the positioning ring groove for positioning. Through the above structure, the diameter of the convex ring is larger than the diameter of the circular through-hole. Not only can the convex ring be used for positioning, but also by cooperating the V-shaped elastic piece with the positioning ring groove, the stability and reliability of the connection can be ensured, preventing the main shaft from loosening or falling off downward, and also having a certain buffering performance, thereby improving the stability and reliability of the installation.

[0030] During the actual application process, a hemispherical housing 8 is fixed to the top of the lamp body, and a round hole 9 is provided on the hemispherical housing; the hemispherical housing can be fixed by screws or integrally processed. The diameters of the round hole and the circular through-hole are matched with the outer diameter of the main shaft. Moreover, on the bottom edge of the round hole, clamping pieces 10 inclined towards the center of the round hole are arranged at equal intervals; the clamping pieces can be fixed by screws or integrally formed on the hemispherical housing. The ends of the clamping pieces extend into the round hole, so that they can be effectively clamped into the slots on the main shaft.
