By providing the bearing 78, the friction force between the threaded barrel 73 and the rotating block 74 can be reduced when the threaded barrel 73 is rotated, making it more labor-saving when the threaded barrel 73 is rotated.

[0031] Reference Figure 2 and Figure 3 As shown, a slide groove 710 is provided on the top of the telescopic plate 75, and a slide bar 79 is fixedly connected to one side of the inner wall of the sleeve 76, and the outer surface of the slide bar 79 is slidably connected to the inner wall of the slide groove 710.

During the expansion and contraction process, the threaded rod 72 will drive the connection block 71 and the rear shell to rotate. At the same time, the threaded cylinder 73 will drive the telescopic plate 75 to slide on the inner wall of the sleeve 76, and drive the slide bar 79 to move synchronously under the limit of the slide groove 710, until the rear shell 1 rotates to a suitable angle, and then rotate the nut 711 so that one side of the nut 711 abuts against one end of the threaded cylinder 73, which can play an auxiliary supporting role between the threaded rod 72 and the threaded cylinder 73, can improve the stability of the overall structure, and thus facilitate the adjustment of the inclination angle of the LED lamp. At the same time, the inclination angle of the LED lamp can be fixed, which is beneficial to prevent the inclination angle of the LED lamp from changing when the body of the engineering vehicle vibrates; when the front cover 3 needs to be installed, the rectangular ring 41 is sleeved on the outer surface of the rear shell, and the block 46 and the pin 43 are inserted into the inner wall of the slot 45 until one side of the first extension block 42 abuts against one side of the second extension block 44, and the auxiliary block 48 is rotated to drive the block 46 to rotate, so that the block 46 enters the shallow groove 47, and the length of the pin 43 is slightly shorter than the inner wall of the slot 45. Then, the deformation of the block 46 itself can be used to fix the first extension block 42 and the second extension block 44, so that the front cover 3 and the rear shell 1 can be fixed, and it is also convenient to disassemble the front cover 3 and to inspect the LED light strip 2.
