A can crusher includes a ratchet bar having a plurality of ratchet teeth longitudinally formed on the bar and having a piston member secured on a front end portion of the bar reciprocatively held in a squeezing chamber formed in a base of the can crusher, a lever pivotally secured to a driving box secured on a rear portion of the base having a first pawl pivotally mounted on a lower end portion of the lever engageable with the ratchet teeth on the ratchet bar, a second pawl pivotally formed on the driving box for preventing a rearward retraction of the ratchet bar, whereby upon an upward pulling of the lever, the first pawl will urge a ratchet tooth of the ratchet bar forwardly to squeeze a can inserted in between the piston member and a compression end plate secured on the base, thereby gradually intermittently pushing the piston member forwardly for crushing the can with a lighter force.
