Abstract:
1. A folding knife assembly, comprising: a knife handle, including a resilient element disposed therein, and a first end of said resilient element being extended proximate to a first end of said knife handle, and a second end of said resilient element being fixed proximate to a second end of said knife handle; a knife body, with a first end pivotally coupled to the first end of said knife handle, such that said knife body can be turned into or out of said knife handle along a pivotal position; and a brake portion, movably disposed at a pivotal position of said knife handle and said knife body, and a part of said brake portion being extended into a shock absorbing portion on said knife body, such that when said knife body is folded completely into said knife handle, the periphery of said brake portion will be pressed precisely by the first end of said resilient element, and the first end of said resilient element will produce a torque to turn said brake portion into said knife handle; and when said knife body is turned gradually out from said knife handle to drive said shock absorbing portion to turn to a predetermined shock absorbing angle and start driving said brake portion to turn, the first end of said resilient element will produce a torque to said brake portion to turn said knife body out from said knife handle, so as to pop said knife body out of said knife handle automatically.
