Abstract
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.
