    Abstract: A projection apparatus includes a light source, a light valve, and a lens module. The light source provides a light beam. The light valve converts the light beam into an image beam. The lens module converts the image beam into a projecting beam and includes a lens and a locking structure. The locking structure is connected to the lens and includes a first plate, a second plate, a moving element, and a first pushing element. The second plate is disposed between the first plate and the lens and firmly fixed to the lens. A groove is formed between the first plate and the second plate, and the groove has withstanding holes arranged along a first direction. The moving element is disposed between the first plate and the second plate. The first pushing element is disposed between the moving element and the second plate.

    Abstract: A compact pneumatic hand tool composed of a body, a cylinder assembly, a sealing pad, a striking assembly, a front cap, a control knob, a ventilation cap and threaded bolts. A first bearing is mounted around a rear end of the striking assembly and an outer rim of the first bearing is securely received in a central hole of the cylinder assembly. A second bearing is mounted on a central shaft of the rotor in the cylinder assembly. The control knob is mounted on the cylinder assembly. A front end of the central shaft of the striking assembly extends out of a front cap and the body is connected to the front cap via threaded bolts so that the striking assembly and the cylinder assembly are sealingly enclosed between the front cap and the body to accomplish the compact and light-weight requirements.
