Abstract: The present invention discloses a trigger knife with a fixable blade position, including a knife shell, a blade holder, a blade, a first elastic member, a trigger, and a limiting mechanism. The blade holder is capable of moving close to or away from the blade outlet in the inner cavity together with the blade. The trigger is rotatably mounted on the knife shell and configured to drive the blade to extend out of the inner cavity. The first elastic member is configured to drive the blade to be retracted into the inner cavity. The limiting mechanism is configured to limit a rotation angle of the trigger, so that the blade can be fixed to at least one preset position in the inner cavity. In the present invention, the blade can be effectively fixed to the at least one preset position in the inner cavity, which can meet usage requirements.

Abstract: A trigger knife, including a knife housing, a knife holder, a blade, an elastic part, a trigger, a linkage assembly, a connecting plate. When the trigger is rotated outwards, the elastic part is deformed, and the linkage assembly drives the connecting plate to move and enables the knife holder to move to a first blade ejection position. When one end of the blade is lifted, the knife holder is enabled to fit with an inner wall of the knife housing, the knife holder to move to a second blade ejection position, and the connecting plate is fastened onto the knife housing and separated from the knife holder. When the end of the blade is moved down, the knife holder is enabled to move down, the elastic part is restored from the deformation to enable the knife holder to move to a rebound position.
