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 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 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 in the storage space and the clip pusher pushing the clips 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 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 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 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 in the storage space and the clip pusher pushing the clips 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 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.
