    摘要: A stapler includes a base and a chute and a cover pivotally coupled together at a rear pivot shaft. The base includes a roller extended downward beyond the middle portion. A lever includes a front portion pivotally coupled to the front portion of the cover and includes a rear handle for operating the lever, and including a block formed in the middle portion for engaging with the roller and for forcing the base toward the chute and the cover. The block includes a tapered surface for engaging with the roller and for allowing the user to operate the lever with less force.
