摘要： A sheath and knife separation control structure includes a sheath formed of a first sheath shell and a second sheath shell and including a knife blade accommodation chamber and a stop block, a knife having a knife blade accommodated in the knife blade accommodation chamber and a stop portion stoppable by the stop block, and a clamping control unit including a clamp pivotally connected to the sheath and a first clamping portion and a second clamping portion adapted for clamping the first sheath shell and second sheath shell of the sheath such that the stop block of the sheath is stopped against the stop portion to lock the knife to the sheath. The stop portion is movable to push away the stop block for allowing separation of the knife from the sheath when the clamping control unit is unclamped from the sheath.

摘要： A multi-purpose tool or apparatus includes multiple mechanical tools. In one implementation, the multi-purpose tool includes an elongated handle, a folding axe, and a folding shovel or spade, as well as a hammer or hammer-head. The folding axe is foldable between an open position and a closed position. The folding shovel is foldable among three positions, which are a closed shovel position, a 90-degree open shovel position, and a 180-degree extended shovel position. The elongated handle is hollow and includes an elongated cavity. A folding saw, as well as a knife and a sheath to protect the knife, are stored within the elongated cavity and can be removed therefrom.

摘要： The present utility knife provides a uniquely improved safety mechanism that increases safety, reliability, and reduces the cost of manufacturing. A shield is locked over the blade by a strut braced between the shield and a stop within the housing. The strut is biased to the locked position by an integrally molded sinuous spring that is designed to force the strut into engagement with the stop and to force the shield to cover the blade, allowing just one cut per actuator pull. The stop structure checks the motion of the strut when locked and closely guides the movement of the strut when unlocked through use of an L-shaped channel. These features reduce the complexity of the safety knife and increase the reliability of the safety mechanism under rough conditions.

摘要： A lockback folding knife having a handle, a blade body pivotally connected in the handle, a constraint member pivotally connected with the handle and having an end abutted with the peripheral edge of the blade body when the blade body is completely stretched out of or received into the handle, a first elastic element having an end fastened in the handle and other end abutted with other end of the constraint member, a locking pin protruded on the constraint member, and a safety switch pivotally connected in the handle and having a locking groove formed thereon corresponding to the locking pin. The locking groove and pin are fastened together when the blade body is completely stretched out of or received into the handle, and the locking groove is escaped from being fastened with the locking pin when the safety switch is applied force.

摘要： A cutter assembly has a blade holder, a slider, an automatic locking device, a screw locking device and a blade. The blade holder has a guiding channel defined in the blade holder and having two inner edges. Multiple engaging teeth are arranged in a line along at least one of the inner edges. The slider is mounted slidably on the blade holder relative to the guiding channel. The automatic locking device is mounted on the slider and has a resilient member selectively engaging at least one of the engaging teeth. The screw locking device is mounted on the slider and has a relative travel distance between the screw locking device and the slider. The blade is mounted slidably in the blade holder and connected to the slider.

摘要： A hand cutter with a retractable blade guard providing an unimpaired view of the blade, when it is placed on the object. The blade guard is unlocked and retracted by a trigger mechanism, which is activated by closing the hand around the cutter handle. The blade guard remains in the retracted position until the trigger is released or a relocking mechanism is activated by putting the blade to use by cutting the object.
