Referring to fig. 9, the main difference between embodiment 2 and embodiment 1 is that the installation position of the light-collecting sheet 17 is different, the light-collecting sheet 17 is installed on the lower end surface of the lamp panel 16, the light-collecting sheet 17 is connected with the lamp panel 16 through a bolt, a movable groove 171 is formed in the middle position of the light-collecting sheet 17, and the movable groove 171 is square to increase the space for the sliding of the connecting rod 23; the edge of the light-gathering sheet 17 is provided with a avoiding groove 172 to avoid the position of the motor 21, so that the possibility that the light-gathering sheet 17 influences the installation of the motor 21 is reduced.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
