Abstract:
1. A folding knife capable of preventing automatic folding, comprising: a blade; a pivot; a handle comprising a first plate, a second plate, and a third plate, wherein the blade is pivotally connected between the first plate and the second plate by the pivot, the second plate is provided with a resilient stopper, the resilient stopper has a first end fixed to the second plate and a second end extending toward the first plate in a slanting manner, and the third plate has a side corresponding in position to the second plate and concavely provided with an engaging hole; wherein when the blade is fully rotated out of the handle, the second end of the resilient stopper presses against an end of the blade and thereby keeps the blade fully rotated out of the handle; and a sliding element slidably positioned on the resilient stopper, wherein the sliding element has an engaging portion extending toward the third plate, a resilient element is provided between an end of the sliding element and the second plate or the third plate; wherein when the blade is received in the handle, the engaging portion is engaged in the engaging hole, and when the blade is fully opened and is pressed against by the second end of the resilient stopper, the second end of the resilient stopper moves toward the first plate in the slanting manner such that the resilient element moves the sliding element in such a way that the engaging portion is disengaged from the engaging hole and presses against the third plate, thereby fixing the resilient stopper at a position where the resilient stopper presses against the blade.
