| description | A projector includes a holding casing having a hole structure, a projection lens movably disposed through the hole structure, a containing casing detachably fixed to the holding casing for forming a containing space, an image projection module disposed in the containing space, and a flexible washer. A first engaging structure is formed on an external surface of the projection lens. The flexible washer jackets the projection lens and has first and second ring structures and a connection ring structure formed therebetween. The first engaging structure is engaged with the second engaging structure of the first ring structure for positioning the first ring structure on the projection lens. The second ring structure is clamped between the holding casing and the containing casing for sealing the containing space cooperatively with the connection ring structure and the first ring structure when the containing casing is fixed to the holding casing. |
