The second plate is provided with a resilient stopper having a first end fixed to the second plate and a second end extending toward the first plate in a slanting manner. The third plate has one side corresponding in position to the second plate and concavely provided with an engaging hole. When the blade is fully rotated out of the handle, the second end of the resilient stopper presses against one end of the blade and thereby keeps the blade fully rotated out of the handle. Thus, when a force applied to the blade is excessively large, the resilient stopper will not be shifted away from the position against the blade. | 11-22-2012 |
20120291292 | Folding knife with safety switch - The present invention relates to a folding knife having a blade pivotally connected to a handle and a positioning device including a resilient plate and a positioning element, wherein the positioning element has a middle section pivotally connected in the handle, and the resilient plate has a first end fixed in the handle and a second end movably pressing against a first end of the positioning element and thereby causing a second end of the positioning element to press against the blade. A safety switch has a first end jutting out of the handle and a second end movably located in the handle and corresponding to the resilient plate. When the safety switch is moved toward the blade, the second end of the safety switch is inserted between the positioning element and the resilient plate to prevent the positioning element from swinging about an axis defined by its middle section. | 11-22-2012 |
