Abstract: A folding knife configured for precise and rapid disassembly and reassembly includes two pivotally connecting and engaging shafts fixedly provided on a first- and a second-side handle portion respectively. The shafts are pivotally connectable and mutually engageable so that the handle portions and a blade can be rapidly and precisely put together, allowing the blade to rotate with respect to the handle portions about an axis defined by the shafts either into or out of the space between the handle portions. The folding knife further includes two locking members provided on the handle portions respectively. The locking members can be locked together to connect the blade to the handle portions securely. By pushing one of the locking members, the locking members can be unlocked from each other to enable disengagement between the shafts and hence rapid and complete separation between the blade and the handle portions.

Abstract: A glass smasher with a rapidly removable protective cover is mounted at one end of a portable object. When a user holds the portable object and presses the front end (i.e., the smashing cone) of the smashing rod of the glass smasher forcibly against a to-be-smashed glass obstacle, the rear section of the smashing rod will be struck such that the smashing cone is instantly driven to smash the glass obstacle. The protective cover can be mounted around the front end of the glass smasher to store the entire smashing cone in the protective cover. When the protective cover is not pulled, the sliding sleeve of the protective cover is pushed by a packing spring and hence pushes a plurality of engaging elements into engagement in the engaging groove of the glass smasher, thereby preventing the protective cover from inadvertent detachment from the front end of the glass smasher.

The plate has a through hole cut therethrough, and first and second stepped portions, wherein the first and second flat portions are formed on an inside wall of the through hole. The stepped portions correspond in position to the flat portions respectively, so as to form the wrench holes with different imperial and metric dimensions. The fixing device has assembly holes cut therethrough and configured for insertion of the screwdrivers, and a lower portion more forwardly protruding than an upper portion thereof for matching with the through hole. Therefore, the fixing device can be mounted into the through hole by a deformation manner and the screwdrivers are positioned in parallel to both sides of the plate.

Abstract: The present invention is to provide an expandable baton with a smasher at the front end of an inner rod thereof, wherein an impact groove, a tapered groove, an aligning groove, and a compression force application groove are sequentially formed in the smasher and the front end of the inner rod. A compression spring can push an impact block in the compression force application groove toward the impact groove in order to position a smashing rod in the corresponding grooves and expose a front conical portion of the smashing rod. When the conical portion is forcibly pressed against an object to-be-smashed, the smashing rod is partially pressed against the wall of the tapered groove and is thrusted into a hitting groove in the impact block upon aligning with the axis of the impact block. The impact block is then driven outward by the compression spring and drives the conical portion to smash the object.
