20140256452 | EXPANSION/COLLAPSE CONTROL MECHANISM FOR POLICE BATON - The present invention is to provide a police baton including an outer tube and an inner tube connected in a telescoping manner, and clutch locking and releasing mechanisms provided at first ends of the inner and outer tubes respectively. When the inner tube is moved outward of the outer tube until the first end of the inner tube presses against a second end of the outer tube, a clutch locking block of the clutch locking mechanism moves laterally outward due to an elastic force and is embedded into a retaining groove on the outer tube, thereby forming a long stick. When a releasing shaft of the releasing mechanism is inserted into a releasing groove on the clutch locking block, the clutch locking block is moved laterally inward and released from the retaining groove, thereby allowing the inner tube to move toward the outer tube for forming a short stick. | 09-11-2014 |
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 |
