[0034] See Figures 1 to 8 As shown, in one embodiment of this utility model, the mounting hole 110a is a threaded hole, and the surface of the rod portion 131 is provided with threads that mate with the threaded hole. The rod portion 131 is threadedly connected to the sleeve 110 and thus passes through and is fixed in the mounting hole 110a. It should be noted that in this embodiment, the rod portion 131 achieves a threaded connection with the sleeve 110 through the engagement of the threaded hole and the threaded hole. This ensures the stability of the sleeve 110 on the lamp post 500 while matching the installation and fixing of the sleeve 110 on lamp posts 500 of different diameters. In this embodiment, the lamp head 1000 is installed on lamp posts 500 of various diameters by rotating the connector 130, simplifying the installation steps of the lamp.

[0035] See Figures 1 to 8 As shown, in one embodiment of this utility model, the thread of the rod 131 extends along its length to the end face of the rod 131, which is used to adjust the length of the rod 131 extending out of the mounting hole 110a. It should be noted that, in this embodiment, by adjusting the extension length of the rod 131 through the mounting hole 110a, the rod 131 or the head 133 abuts against the lamp post 500 extending into the sleeve 110, thereby enabling the sleeve 110 to be installed on lamp posts 500 of various diameters. By adjusting the extension length of the lamp post 500, the stability of the assembly between the sleeve 110 and the lamp post 500 is improved.

[0036] See Figures 1 to 8 As shown, in one embodiment of this utility model, a first hexagonal blind hole 131a is provided on the surface of the rod 131 opposite to the head 133, so that the rod 131 is rotated through the first hexagonal blind hole 131a until the head 133 abuts against the lamp post 500.

When the diameter of the lamp post 500 is close to the diameter of the sleeve 110, the rod 131 passes through the outside of the sleeve 110 to the mounting hole 110a. During the insertion of the rod 131, the head 133 is restricted by the mounting hole 110a, so the end of the rod 131 away from the head 133 abuts against the lamp post 500 extending into the sleeve 110, and the sleeve 110 is thus installed and fixed to the lamp post 500. When the diameter of the lamp post 500 is much smaller than the diameter of the sleeve 110, the rod 131 passes through the inside of the sleeve 110 to the mounting hole 110a. The head 133 is restricted by the mounting hole 110a, so the end of the head 133 away from the rod 131 abuts against the lamp post 500 extending into the sleeve 110, and the sleeve 110 is thus installed and fixed to the lamp post 500. This utility model simplifies the installation steps of the lamp fixture by adjusting the insertion direction of the connector 130 to assemble the lamp head 1000 on lamp posts 500 of different diameters.

[0039] See Figures 1 to 8As shown, in one embodiment of this utility model, a groove 110b is provided on the end face of the sleeve 110.
