[0045] At the same time, during assembly, the second contact piece is inside the housing and the end is at the top of the rotating gear; and the connecting contact piece is at the bottom surface of the rotating gear, and a conductive column 11 is arranged on the rotating gear and abuts against the connecting contact piece; in this embodiment, the connecting contact piece includes an n-shaped connecting portion 281 and a circular ring portion 282 integrally formed at one end of the n-shaped connecting portion and bent outward; during assembly, the circular ring portion is at the bottom surface of the rotating gear, and the bottom surface of the conductive column is attached to the circular ring portion. The conductive column is mainly a copper column or an elastic piece, mainly used for electrically connecting the second elastic piece with the connecting contact piece when rotating. In the actual application process, the position of the conductive column and the position of the second contact piece can be adjusted through the rotating gear. In this embodiment, the number of the first Z-shaped contact pieces and the second Z-shaped contact pieces is two each, and the two first Z-shaped contact pieces are symmetrically arranged on the rotating pillar, and the two second Z-shaped contact pieces are symmetrically arranged on the rotating pillar.

[0047] In actual application, in order to improve the effectiveness of the overall structure, the top surface of the rotating gear is provided with a central cavity 5 and an annular groove 6; wherein the central cavity is concentrically arranged with the annular groove, and the annular groove is located outside the central cavity; the rotating pillar can be rotatably arranged directly above the central cavity, and the conductive column is located at the inner wall of the central cavity; the end of the second contact piece is located in the annular groove, and when the rotating pillar rotates, the bottom plate end of the first Z-shaped contact piece abuts against the second contact piece.

Since the distance between the conductive column and the second contact piece changes, and the positions of the first Z-shaped contact piece and the second Z-shaped contact piece are relatively fixed, the first Z-shaped contact piece and the second Z-shaped contact piece can adjust the contact area with the conductive column or the second contact piece when they rotate. At the same time, when the rotating pillar rotates, the first Z-shaped contact piece and the second Z-shaped contact piece can be folded or unfolded synchronously, and the unfolding angle can be adjusted to meet the use of track grooves of different widths, which is conducive to improving its scope of use.

[0048] In actual application, the side of the rotating pillar is integrally formed with a toggle handle 7; the side of the shell is provided with a toggle bar groove 8, the toggle handle is in the toggle bar groove, and the toggle handle drives the rotating pillar to rotate in the shell.

After installation, it can be limited by the end caps at both ends of the lamp body, or the housing can be limited and locked by screws to ensure the stability and reliability of use.

[0050] Meanwhile, in the actual application process, the rotating pillar includes a first half pillar 271 and a second half pillar 272 fixed by snap or screw; the first Z-shaped contact piece and the second Z-shaped contact piece are located inside the first half pillar and the second half pillar. It is convenient for the disassembly and assembly operations of the internal structure and improves the disassembly and assembly efficiency.
