ABSTRACT:
A staple ejection device for a power stapler includes a guide plate having two hooks, a strip and a cover member are respectively and pivotally connected to the two lugs. The cover member has a retaining plate which defines a gap between the retaining plate and the cover member. A control member is retained in the gap between the retaining plate and the cover member, two springs biased between the control member and a positioning block of the cover member so that the control member is movable in the gap. The control member has two buttons each of which has a cone-shaped end which is engaged with the hook on the guide plate. The cover member is pivoted away from the guide plate by pulling the buttons to disengage the two buttons from the hooks.
