The ratchet mechanism including a first pawl and a second pawl each tiltably supported in the housing and disposed on respective opposed sides of the rack member and a buckling spring interposed between the first pawl and the second pawl and constrained in a slot formed in the rack member, wherein the buckling spring is dimensioned so as to bow in one of a proximal direction and a distal direction.
