Abstract: A projector includes a projector body, a lens module with a lens, and a gear module. The lens module and the gear module are arranged in the projector body. The gear module is operable to adjust a height of the lens and keep an angle of the lens, in response to the gear module being rotated.

Abstract: A projector includes a projector body, a lens module, and a base rack. The front panel of the projector body defines a though hole. The lens module includes a lens body rotatably mounted to the projector body, a sliding bracket, and a lens extending from the lens body to extend through the through hole of the projector body, and a sliding bracket connected to the lens body via parallel connecting poles. The sliding bracket is slidably mounted to the base rack. The base rack is rotatably mounted to the projector body. A height of the lens is operable to be adjusted by changing the positions of the sliding bracket on the base rack.

Abstract: A fastener includes a cylinder and a draw hook. The cylinder includes a main body, two resilient arms extending from an end of the main body, and a flange extending from a circumference of an opposite end of the main body. A number of protrusions spaced in the axial direction of the main body extends from an inside surface of each of the resilient arms. The draw hook includes a post slidably received in the cylinder, a taper-shaped engaging portion extending from an end of the post and exposed out of distal ends of the resilient arms, and a handle extending from an opposite end of the post.
