Abstract (en)
[origin: US4602535A] A mechanism for preventing premature opening of a tool having two elongate handles comprising a carrier having a row of teeth at one edge and a spring-affected, pivotable pawl co-operating with the row of teeth. The pawl operates as a bistable rocker swingable by end stops at both ends of the row of teeth from a first lateral position for engagement with the row through an instable middle position into a second engagement-free lateral position. The two ends of the spring affecting the pawl and a pivot pin on which the pawl is mounted lie along one straight line when the pawl passes through the instable middle position.
