Abstract

The utility model relates to a safety mechanism of a linear cutting stapler, which comprises a nail anvil component shell, a nail bin component shell and a trigger button. The trigger button is connected with a push block, and a nail anvil is fixedly arranged in the nail anvil component shell; and the tail part of the push block is provided with a clamp block, a safety block is arranged on the nail bin component shell, the middle part of the safety block is connected with the nail bin component shell in a rotating way, the front part of the safety block limits the clamp block, a torsion spring is arranged between the safety block and the nail bin component shell, and the tail part of the nail anvil is provided with a press block in a position corresponding to the tail part of the clamp block. Since the nail bin component shell is connected with the safety block in a rotating way, the push block can not move forwards in the non-operating state, thereby avoiding the possibility that the trigger button is pushed by mistaken prior to the operation. After interlocking of the nail anvil component and the nail bin component during operation, the press block on the tail part of the nail anvil fixedly arranged in the nail anvil component shell can push the tail part of the safety block downwards, so that the hook part of the front end of the safety block can warp up, and the push block can be free from limitation of the safety block, thereby realizing the normal operation. The utility model has the advantages of simple and convenient operation, reasonable design and high practicality.
