Each of the racks includes a first set of teeth provided longitudinally therealong. Each of the first pinion and the second pinion includes a second set of teeth provided circumferentially therearound. The first pinion and the second pinion are configured to rotate along the first rack and the second rack respectively through engagement of the second set of teeth with the first set of teeth. The timing bar includes a first end and a second end. The first end and the second end are configured to be coupled to the first pinion and the second pinion respectively so that the first and second pinions rotate as one. The first pinion is configured to be movable with respect to the timing bar along a longitudinal axis of the timing bar.
