• an inner side of the arc strip having teeth;
• a seat installed below the upper cover by using a connector;
• a button installed to the seat and resisting against the arc strip;
• an out periphery of the button being formed with teeth:
• the teeth of the button being engaged to the teeth of the arc strip, and thus the button will be driven to rotate by rotating the arc strip;
• the button having a teethed through hole;
• an inner periphery of the teeth through hole being teethed;
• and
• a light adjuster installed below the button;
• the light adjuster having a teeth projection;
• a periphery of the teethed projection being teethed;
• the teethed projection being located within and engaged to the teethed through hole;
• the rotation of the button will drive the light adjusted and thus the actuation of the light adjuster being controllable by the button, an O ring being located between the button and the light adjuster;
