In a further technical scheme, a battery bin is arranged in the middle of the rear end of the projection pen main body, a rear cover plate is inserted into an opening of the battery bin, and a lifting lug is fixedly connected to the surface of the rear cover plate.

The battery can be installed to the battery compartment that sets up, realizes the change of battery, and the back shroud of setting can increase the projection pen main part leakproofness, and the rope can be installed to the lug of setting to make equipment convenient to carry.

In a further technical scheme, the projection pen main part middle part one side fixedly connected with light, the draw-in groove has been seted up to projection pen main part front end head, draw-in groove and preceding rubber sleeve buckle joint.

The user can change preceding rubber sleeve, only need insert the draw-in groove with rubber sleeve buckle before new to realize the installation.

The utility model has the advantages that:

1. the ultraviolet lamp and the reflector plate can realize the sterilization effect, so that the device is more sanitary and prevents the infection of germs;

2. through the protective housing, preceding rubber sleeve and the back rubber sleeve that set up, can protect projection pen main part both ends and surface to prevent that the equipment main part from damaging, influencing the equipment leakproofness.
