The top cover 32 and the lampshade 33 are no longer required to be manually disassembled and assembled, which greatly saves manual operation steps, improves maintenance efficiency, and is more convenient to use. In the process of extending the telescopic lamp pole 1 to raise the height of the lamp head 3, the driving component 48 can pull the push rod 45 to slide close to the side of the telescopic lamp pole 1 until it is reset. At the same time of reset, the lampshade 33 and the top cover 32 are closed and covered on the outer wall of the base 31. Then the telescopic lamp pole 1 continues to extend, and the limiting component 47 continues to limit the push rod 45, and then the lampshade 33 and the top cover 32 are kept pressed against the outer wall of the base 31. Finally, the lamp head 3 rises to the highest point. In actual use, a rubber sealing pad can be fixed on the upper edge of the lampshade 33 and the upper edge of the base 31, thereby improving the sealing effect of the lamp head 3.

[0048] The limit assembly 47 includes a locking strip 471 symmetrically slidably connected to the end of the support rod 2 near the telescopic lamp pole 1 through a sliding hole, the locking strip 471 is U-shaped, and an intermediate groove 472 is provided at the end of the support rod 2 near the locking strip 471.

[0049] In such Figure 1In the state shown, the push rod 45 is in a posture that makes the lampshade 33 and the top cover 32 keep covering the outside of the base 31. At this time, the push rod 45 is located at the end position closest to the telescopic lamp pole 1 and is locked by the limit assembly 47. When the telescopic lamp pole 1 is retracted and the lamp head 3 descends, the upper end of the drive plate 482 is first inserted into the middle groove 472, and then continues to enter the avoidance groove 484, and then the drive column 485 enters the vertical portion 4831 of the drive groove 483, and then the drive column 485 continues to be inserted into the vertical portion 4831 of the drive groove 483, and at the same time, the drive The inclined portions 4821 on both sides of the upper end of the movable plate 482 will contact the upper ends of the locking strips 471, and then the lamp holder 3 continues to descend. The inclined portions 4821 push the two locking strips 471 to slide to both sides and stretch the first spring 473. The lower ends of the locking strips 471 move out of the card holes 474 to release the locking of the push rod 45. While contacting and locking, the upper ends of the locking strips 471 abut against the outer walls of both sides of the driving plate 482, and the driving column 485 reaches the lower end of the vertical portion 4831 of the driving groove 483. Then the lamp holder 3 continues to descend. At this time, the push rod 45 has been unlocked, and then the driving column 4 85 enters the inclined portion 4832 of the driving groove 483, and then the lamp head 3 continues to descend, pushing the push rod 45, so that the gear 41 rotates to make the lamp cover 33 and the top cover 32 flip open until they are fully opened. At this time, the upper end of the locking strip 471 still abuts against the outer wall of the driving plate 482 located at the upper end of the inclined portion 4832, so that the push rod 45 is unlocked and pushed. When the lamp head 3 continues to rise after the maintenance work is completed, the process is opposite to the above.
