Abstract

The utility model relates to a stapler with an improved middle supporting front sleeve structure. An upper slide sleeve sheet and a lower slide sleeve sheet are matched between the middle supporting part and the middle supporting front sleeve of the stapler. The bottom end of a lower slide sleeve is led to a little protrude out of the bottom edge of the middle supporting front sleeve. The upper slide sleeve sheet and the lower slide sleeve sheet are properly treated through hardening for pressing and binding after the upper slide sleeve sheet and the lower slide sleeve sheet are pressed down. The bottom end of the lower slide sleeve sheet can press objects which are bound on a needle striking plate on the bottom surface of the stapler. The utility model can not easily deform by means of the hardening structure of the lower slide sleeve sheet to ensure that the middle supporting front sleeve and a middle supporting bottom end can not deform. In addition, stitching needles can also smoothly downwards pressed without bending to improve a user's striking and binding efficiency.
