The base has a track and a fixed jaw formed at a first end thereof and a movable jaw provided on the track at a second end thereof. A first rectangular recess is formed on an underside of the base for receiving the rectangular positioning body. The rectangular positioning body has a central slot extending longitudinally and defining two longitudinal side walls. A plurality of holes are formed on each longitudinal side wall of the positioning body. A second recess is provided on an underside of the positioning body and extending along a length of the slot in the longitudinal direction and extending transversely a distance half the width of the longitudinal side walls such that the holes are notched. A projection protrudes from an end of the top surface of the positioning body and is located below the fixed jaw when the positioning body is received in the first recess of the base.
