发明名称 Projector having an adjustable height
摘要 A projector adjustable in height includes a housing formed with a longitudinal slit at one side thereof, which slit is transverse to the axis of projection of the projector, a handle which has an axis of rotation transverse to the projection axis and to the slit, and which penetrates the housing at least partially. The handle projects from the lower portion of the housing through the slit, and may be pivoted about a point within the housing to a selected position in a direction transverse to the direction of the axle, as well as be rotated about the axis. A clamping device is substantially disposed about the housing point for clamping the handle at a selected position.
