1 and 2 and connecting

plates

3 and 4 connecting the two vertical plates together. The outer side of one of the connection plates 3 is provided with a bearing plate 7, and the bearing plate 7 has a plane 71 for bearing and fixing the quick connection device 200. The

vertical plates

1 and 2 are provided with U-shaped slots 101, and the opening of the U-shaped slot 101 is an oblique edge opening 102. In order to enhance the strength of the

vertical plates

1 and 2, a plurality of rib plates are arranged at the edge of the U-shaped open groove 101, such as a rib plate 5 arranged near the bottom of the U-shaped open groove 101,

rib plates

6 and 8 arranged at the oblique edge opening 102 of the U-shaped open groove 101, and the like.

The lamp holder 300 is used for fixedly supporting the lamp housing 22, and the work lamp is covered inside the lamp housing 22. The lamp holder 300 is fixedly connected with the lampshade 22 through bolts 21, and a vehicle lamp is arranged in the lampshade 22. The lamp holder 300 comprises two parallel side vertical plates 19 and a rib plate 20 connecting the two side vertical plates 19. The rib plate 20 is matched with the inclined edge opening 102 of the U-shaped groove 101 on the

vertical plates

1 and 2 on the lamp holder. A through hole 23 is arranged below the rib plate 20 on the side vertical plate 19, and a pin shaft 18 is arranged in the through hole 23 in a penetrating way. The pin shaft 18 can be clamped in the U-shaped slot 101 on the

vertical plates

1 and 2 of the base 100, so that the lamp holder 300 can be quickly assembled on the base 100. The rib plate 20 is used for positioning the position of the lamp holder 300 clamped in the U-shaped slot 101 of the base 100.
