Straight cutting stapler

Abstract

The invention discloses a straight cutting stapler. The straight cutting stapler comprises an upper forceps holder, a lower forceps holder, a first mounting position and a detachable push button, wherein the upper forceps holder comprises a nail push rod, a push block connected with a near end of the nail push rod and a nail bin connected with a far end of the nail push rod, the lower forceps holder comprises a nail anvil and a nail anvil shell matched with the nail anvil, the first mounting position is arranged on the push block, and the detachable push button is arranged on the push block and matched with the first mounting position. Since the first mounting position and the detachable push button matched with the first mounting position are arranged on the push block of the straight cutting stapler, during transportation in a package, the detachable button can be detached to prevent the push button from protruding over the surface of an instrument and occupying package space, and meanwhile, external force is prevented from acting on the push button to result in breakage and separation of the push button and the push block.
