Abstract:
1. A torque wrench for applying torque to a component, the torque wrench comprising: an engaging member for engaging a component to be rotated about an axis; at least one ratchet connected to said engaging member; a lever connected to said engaging member via said at least one ratchet such that rotation of said lever in one sense about said axis applies torque to said engaging member and rotation of said lever in the opposite sense about said axis applies torque below a predetermined value to said engaging member; and a connector member pivotably connected to said lever remote from said engaging member and adapted to be engaged by at least one actuator having reciprocating linear movement in use, to alternately rotate said lever in opposite senses about said axis; wherein said lever in use abuts said connector member, and sad connector member in use is slidable relative to said at least one actuator in a direction transverse to the direction of said reciprocating linear movement such that said connector member applies a force to said lever only in a direction parallel to said reciprocating linear movement throughout said reciprocating linear movement.
