As shown in FIG. 2, the fixed clip 3 is provided with a fixed arm 31, a movable arm 32 and an elastic member 38. The plane shape of the fixed clip 3 is similar to an equilateral triangle, the fixed arm 31 roughly corresponds to the base of the equilateral triangle, and the movable arm 32 roughly corresponds to the two sides of the equilateral triangle. In order to have a neat and beautiful appearance in the stored (folded) state, the lamp cap 2 can be made into the same planar shape as the fixing clip 3. It should be pointed out that: the shape of the lamp cap 2 and the fixing clip 3 can be arbitrary, and the use performance of the lighting fixture 1 will not be affected.

The connecting part 4 is provided with a first rotating shaft 101 and a second rotating shaft 102 that are parallel to each other. The lamp cap 2 is connected to the connecting part 4 through the first rotating shaft 101. The lamp cap 2 can rotate a predetermined angle around the first rotating shaft 101, and the fixing clip 3 By connecting the second rotating shaft 102 with the connecting portion 4, the fixing clip 3 can rotate about the second rotating shaft 102 by a predetermined angle. Due to the existence of the first rotating shaft 101 and the second rotating shaft 102, the lamp head 2 and the fixing clip 3 can rotate relative to each other (tilting action) to open or close the lighting fixture 1.
