Press-fit type secondary percussion prevention safety mechanism of endoscope linear cutting anastomat

The invention relates to a press-fit type secondary percussion prevention safety mechanism of an endoscope linear cutting anastomat. A locking assembly is rotationally connected into a nail bin frame; limiting grooves are formed in the bottom of the cartridge frame; the locking assembly is connected with a pressing rod arranged at the forward end of the cutter, and the limiting groove is connected with a check block arranged on the side of the cutter in a matched mode. The locking assembly comprises a locking part and an unlocking part. The locking part comprises a locking block connected with the inner wall of the nail bin frame through an elastic element. In other words, when the cutter moves forwards, the first inclined face on the upper portion of the pressing rod slides on the lower portion of the locking block, the cutter moves downwards at the same time, the check block enters the limiting groove, the cutter is limited to continue to move forwards, and locking is achieved; and an unlocking block arrang
