The rear shell 302 can be locked and fixed on the top of the front panel 301, and the rear shell 302 is provided with a positioning seat 6 on the lower side of the front panel 301. The positioning seat 6 is provided with a shaft hole 61 that passes through the upper and lower parts. The shaft portion 11 of the shaft clamp 1 of the rail head 20 passes through the shaft hole 61 from the upper side of the rear shell 302. At the same time, a corrugated gasket 7 can be sleeved between the embedding portion 12 of the shaft clamp 1 and the rear shell 302.

[0044] Two circumferentially spaced limiting portions 62 are disposed on the outer periphery of the rotating shaft hole 61 of the positioning seat 6 , two circumferentially spaced positioning recessed holes 63 are formed between the limiting portions 62 , and a positioning groove group 64 is disposed between the two limiting portions 62 and radially inside the positioning recessed holes 63 .

The positioning protrusion 4211 can elastically press against the positioning recessed hole 63. The rotation of the rotating shaft portion 11 drives the spring piece 4 to rotate, so that the positioning protrusion 4211 of the positioning spring piece 421 can be respectively positioned in two positioning recessed holes 63 with a circumferential interval of 90 degrees. When the elastic positioning portion 42 corresponds to the two positioning recessed holes 63, it is circumferentially pressed against the two limiting portions 62 to avoid excessive rotation.

[0053] In this embodiment, the spring sheet 4 and the spring needle 2 are separated by the spring needle seat 3, so the spring sheet 4 is separated by the positioning seat 6, so that the positioning spring sheet 421 of the positioning portion 42 can be a structure bent toward the positioning recessed hole 63 to enhance the elastic abutment effect, and the positioning portion 42 also includes a positioning frame 422 surrounding the outer periphery of the positioning spring sheet 421. When the positioning spring sheet 421 is positioned in the positioning recessed hole 63, the positioning frame 422 abuts against the side of the limiting portion 62 in a circumferential direction to protect the positioning spring sheet 421.

[0054] A convex portion 631 is disposed on one circumferential side of each positioning recess 63 close to another positioning recess 63 , so as to provide a damping feeling when the spring piece 4 rotates over the convex portion 631 and approaches, thereby improving the rotation feel.

[0055] In summary, the shaft structure 10 of the utility model can be rotatably inserted and matched in the shaft hole 61 of the lamp body 30 by means of the shaft portion 11 provided on the rail head 20, and a positioning seat 6 is provided on one side of the shaft hole 61, and a spring piece 4 is provided on the shaft portion 11. The spring piece 4 is movably positioned and matched with the two positioning recessed holes 63 on the positioning seat 6 as the shaft portion 11 rotates and is limited to the two limiting portions 62.

In some places where the light is not required to be too strong or too bright, the rotation can be adjusted, and vice versa. In particular, the right angles of two walls can use the shaft structure 10 to realize the rotation adjustment adaptation of the lamp body 30.

[0056] In this embodiment, two positioning recessed holes 63 are arranged at an interval of 90 degrees to satisfy the reciprocating horizontal and vertical switching changes, but it is not limited to this. The number and circumferential spacing angle of the positioning recessed holes 63 can be adjusted according to actual needs.
