When the position of the movable assembly 2 needs to be adjusted, the movable assembly 2 only needs to be pulled along the length direction of the telescopic connecting piece 12, so that the position of the movable assembly 2 is adjusted more conveniently and simply.

In a specific embodiment, as shown in fig. 2 and 3, the telescopic connecting member 12 is a cylinder, and both ends of the telescopic connecting member 12 are disposed at the opening. Specifically, the lamp cap 11 is covered at one end of the telescopic connector 12, and the driving assembly 5 is disposed in the telescopic connector 12.

In particular, the damping structure 7 refers to a component that can maintain a relatively static relationship between the movable assembly 2 and the telescopic link 12 when the movable assembly 2 is not subjected to external pulling or pushing forces. The poor adjustment accuracy caused by the too high sliding speed of the telescopic connection 12 in the sliding channel 21 can be avoided to a certain extent under the action of the damping structure 7. Meanwhile, after the position of the movable assembly 2 is adjusted to the designated position, the movable assembly 2 can be fixed through the damping structure 7, so that the movable assembly 2 is prevented from sliding continuously.

Meanwhile, after the movable assembly 2 is adjusted in place, the relative fixation between the telescopic connecting piece 12 and the movable assembly 2 can be realized through the friction force between the outer ring of the elastic ring 71 and the inner wall of the sliding channel 21.

In an alternative embodiment, the number of the elastic rings 71 may be multiple, and the multiple elastic rings 71 are sequentially spaced along the length direction of the telescopic connecting piece 12, so that the positioning effect of the damping structure 7 is better.

The fixed component may be a threaded rod, at least a portion of which is located in the sliding channel 21 and is in threaded connection with the movable component 2, and the movement of the threaded rod may be achieved by rotating the threaded rod. When the telescopic connecting piece 12 and the movable assembly 2 are required to be fixed, the threaded rod can be made to approach and abut against the telescopic connecting piece 12 to achieve fixation of the telescopic connecting piece 12 by rotating the threaded rod, and when the telescopic connecting piece is not required to be fixed, the threaded rod is only required to be reversely rotated, so that the threaded rod is far away from the telescopic connecting piece 12, and free sliding of the telescopic connecting piece 12 and the movable connecting piece can be achieved.

In one embodiment, as shown in fig. 1 and 6, an anti-rotation structure 8 for preventing rotation of the telescopic link 12 is further provided between the telescopic link 12 and the inner wall of the sliding channel 21.
