Zusammenfassung:	A projection module includes a base, a light source, a light valve, a lens module, and an adjustment module. The light source is disposed on the base and capable of providing an illumination beam. The light valve is disposed on the base and capable of converting the illumination beam into an image beam. The lens module is slidably disposed on the base and capable of projecting the image beam. The adjustment mechanism includes a rolling wheel and a slide pin. The rolling wheel is pivotably mounted to the base and includes a slide groove. The slide pin is fixed to the lens module and extends into the slide groove. The rolling wheel is capable of pivoting to drive the slide groove to pivot and the slide groove moves the slide pin to drive the lens module to move with respect to the base when the slide groove pivots.
