发明名称 Folding knife
摘要 The present invention discloses a folding knife, which comprises a blade pivotally coupled to an end of a knife handle for pivoting out of the knife handle or being received into the knife handle, a resilient bar with an end fixed to another end of the knife handle and another end extended to the blade proximate to the pivotal connecting position, and a push switch installed proximate to the pivotal connecting position with an end extended to a surface of the knife handle and another end passed through the knife handle and against the blade, such that when the push switch is pushed to drive the blade to turn to a predetermined angle, the resilient bar produces a torque to turn the blade out from the knife handle automatically, so that a user simply needs to push the push switch for the control of turning the blade out from the knife handle.
