detailed description

As shown in FIG. 1 , FIG. 2 and FIG. 3 , the utility model comprises a box body 1 . The reverse side of the box body 1 is an open end, and the front side thereof is a closed end, and the reverse side thereof is provided with a fixed connection with the box body 1 . Back cover 2,

The casing 1 is provided with a connecting pipe 3 having the same depth as the casing 1. The side wall of the connecting pipe 3 is provided with a fixing groove 14, and the connecting pipe 3 and the front surface of the casing 1 The connection is provided with a circular window 4, the connection A spring 5, a limiting piece 15 and a spherical illumination device 6 are disposed in the nozzle 3 from the reverse side of the casing 1 to the front side thereof, and one end of the spring 5 is in contact with the rear cover 2, and the other end is The spherical illumination device 6 is in contact,

The spherical illumination device 6 comprises a spherical body 7 in which a cavity 8 is opened on one side, and the outer end of the cavity 8 is fixedly connected with a transparent front cover 9 inside the cavity 8 A reflector 10 and a light source 11 at the bottom of the reflector 10 are disposed, and between the inside of the casing 1 and the outside of the connecting pipe 3, a control circuit 18 and a battery 19 are provided, and the inside of the body 7 The bottom of the cavity 8 is provided with a wire through hole 13 , and the light source 11 is electrically connected to the control circuit 18 through a wire passing through the wire through hole 13 , and the outer wall of the body 7 is offset from the wire through hole 13 . A limiting protrusion 12 is disposed on the side wall of the connecting tube 3, and a fixing slot 14 is disposed in the fixing slot 14, and the limiting blocking piece 15 is adjacent to the body 7.
