Reversible ratchet mechanism driving away investment.

摘要

Key (20; 120) ratchet comprising a handle (22) with a surface (30) outside; a head (24) coupled to the handle (22); a gear (34) arranged revolving head (24) and having teeth (36) ratcheting; a pawl (44) rotary movable between a first pawl position in which the pawl (44) is engaged with the gear (34) to allow rotation of the gear (34) in a first direction and substantially prevent rotation of gear (34) in a second direction and a second pawl position wherein the pawl (44) is engaged with the gear (34) to allow rotation of the gear (34) in the second direction and substantially prevent rotation of the gear (34) in the first direction; a rod (66; 166) rotatable elongated provided in the handle (22) with an actuator (78) disposed at a first end of the rod (66; 166) and inclined relative to the axis (A; D) of the bar ( 66; 166); and a mechanism for control or management disposed on the outer surface (30) of the handle (22) and coupled to the rod (66; 166); characterized in that the actuator (78) includes a plunger (80) and a spring (82) and can rotate the bar (66; 166) from a first rod position wherein the actuator (78) deflects the catch (44) towards the first pawl position to a second rod position wherein the actuator (78) deflects the catch (44) to the second pawl position.
