A surgical clip applier comprising an outer tube with a jaw protruding from a distal end of the outer tube and a handle mounted at a proximal end of the outer tube , in the outer tube from top to bottom sequentially arranged comprising: a feeding rod with a proximal end connected to the handle presenting a reciprocate movement relative to the outer tube from a movement of the handle , and the feeding rod moving a distal most clip (A) into the jaw ; a clip carrier which is a square groove with an upward opening side placed in the outer tube fixedly and, the clip carrier defining a storage space inside and multiple clips (A) are held in the storage space from a distal end to a proximal end in sequence, and a window defined through a bottom of the distal end of the clip carrier ; and a clip pusher located at a proximal side of a proximal most clip of the multiple clips (A) in the storage space and the clip pusher pushing the clips (A) to the distal end of the outer tube from a proximal side of the clip carrier ; and a wedge plate with a proximal end connected to the handle presenting a reciprocate movement relative to the outer tube from the movement of the handle , and the wedge plate being applied to close the jaw ; characterized in that an elastic leaf extends toward the distal end of the outer tube from the clip pusher , the elastic leaf deformed elastically by abutting against a bottom surface of the clip carrier , the elastic leaf being moved to the distal end sequentially according to a movement of the clip pusher ; and wherein when the handle is triggered again after a last clip (A) is fired, the clip pusher drives the elastic leaf to move to a position aligning with the window , the elastic leaf extends through the window and blocks the wedge plate from moving to the distal end of the outer tube . a feeding rod with a proximal end connected to the handle presenting a reciprocate movement relative to the outer tube from a movement of the handle , and the feeding rod moving a distal most clip (A) into the jaw ; a clip carrier which is a square groove with an upward opening side placed in the outer tube fixedly and, the clip carrier defining a storage space inside and multiple clips (A) are held in the storage space from a distal end to a proximal end in sequence, and a window defined through a bottom of the distal end of the clip carrier ; and a clip pusher located at a proximal side of a proximal most clip of the multiple clips (A) in the storage space and the clip pusher pushing the clips (A) to the distal end of the outer tube from a proximal side of the clip carrier ; and a wedge plate with a proximal end connected to the handle presenting a reciprocate movement relative to the outer tube from the movement of the handle , and the wedge plate being applied to close the jaw ; characterized in that an elastic leaf extends toward the distal end of the outer tube from the clip pusher , the elastic leaf deformed elastically by abutting against a bottom surface of the clip carrier , the elastic leaf being moved to the distal end sequentially according to a movement of the clip pusher ; and wherein when the handle is triggered again after a last clip (A) is fired, the clip pusher drives the elastic leaf to move to a position aligning with the window , the elastic leaf extends through the window and blocks the wedge plate from moving to the distal end of the outer tube . <EOS>
