Abstract
A safety device for a power stapler includes a pushing member movably received in a magazine of a power stapler. The pushing member has a protrusion extending from a top thereof and a block is fixedly connected to a side of the protrusion. A sliding member is slidably connected to the barrel of the power stapler and a recess defined in an end of the sliding member. When the last staple runs out, the block on the pushing member is engaged with the recess of the sliding member to stop the movement of the sliding member and the ejecting mechanism.
