Jaw actuation mechanism

An actuation mechanism comprising:

• a first jaw rotatable about a jaw axis and comprising a first slot;
• a second jaw rotatable about the jaw axis and comprising a second slot;
• a slider moveable along a slider axis between a first position and a second position and movably engageable with the first and second jaws, which slider comprises a first protrusion slidably receivable within the first slot and a second protrusion slidably receivable within the second slot, wherein each slot extends in a direction which is non-parallel to the slider axis when the respective protrusion is engaged with the slot;
• a return attachable to the actuation mechanism and spaced apart from the slider;
• and
• an actuation member operably engageable with both the slider and the return, the actuation member comprising a first end, a second end, a first portion that extends from the first end to the return, and a second portion that extends from the return to the second end, the first portion being fixable to the slider whereby movement of the first portion away from the return causes the slider to move towards the first position and movement of the second portion away from the return causes the slider to move towards the second position, wherein the actuation member is slidably engageable with the slider between the return and the second end,
• wherein the slider comprises a first member receiving portion and a second member portion, and the actuation member is fixable to the slider via the first member receiving portion and slidably receivable within the second member receiving portion.
