<p>Disclosed is a disposable stapler with a mechanism for preventing secondary triggering. The disposable stapler comprises an anvil assembly (1), a reload assembly (2) forming a stapling gap with the anvil assembly, a mobile grip (3), a fixed grip (4), a transmission assembly (5) mounted in the fixed grip (4), a pushing assembly (6) mounted cooperatively with the transmission assembly, a safety device (7) and an anti-triggering sheet (8), with two rows of holes provided on the anti-triggering sheet (8), and a vertically symmetric snap strip (83) is provided on one side of the anti-triggering sheet (8); a row of countersinks (42, 43, 44) and a snap platform (41) fitted with the snap strip on the anti-triggering sheet (8) are provided on one side of an inner chamber of a housing for the fixed grip (4); the safety device (7) is fixed on one side of the pushing assembly (6); the anti-triggering sheet (8) is snap-fitted in the housing of the fixed grip (4), and closely abuts one side of the safety device (7). The stapler is simple in structure, easy to assemble, and safe to use. The stapler is automatically locked after the triggering is complete, and cannot be triggered a second time.</p> |
