Abstract:
A folding knife configured for safe and rapid disassembly and reassembly includes an upper handle portion having two engaging grooves respectively adjacent to its two ends, and a lower handle portion having an engaging and pivotally connecting shaft and an engaging and locking shaft respectively adjacent to its two ends. The two shafts are engageable in the engaging grooves respectively. A blade is mounted around the engaging and pivotally connecting shaft and rotatable into and out of a space between the handle portions. A pushable locking member is rotatably connected to the engaging and locking shaft and can be pushed to allow or prevent disengagement between the engaging and locking shaft and the corresponding engaging groove. Thus, user only has to push the pushable locking member, the upper handle portion and the blade will be in a detachable from or securely connected to the lower handle portion as a whole.

Claim (Index 8):
The folding knife of  claim 6 , further comprising an elastic plate mounted between the upper handle portion and the lower handle portion or between the upper handle portion and the spacer, wherein a portion of the elastic plate that is adjacent to a rear end of the elastic plate is fixed on the inner side of the lower handle portion at a position adjacent to the rear end of the lower handle portion; the elastic plate is provided with a stopping portion adjacent to a front end of the elastic plate; when the blade has been rotated completely out of the blade storage space, the stopping portion is engaged with the rear end of the blade to prevent the blade from rotation and hence from entering the blade storage space; and the blade becomes rotatable again and hence able to be stored into the blade storage space only after the stopping portion is disengaged from the blade by an external force.
