First and second connectors each have a front end and a rear end to become rotatably engaged to each other between the front and rear ends thereof. The first and second connector front ends are rotatably connected to the first and second side portions An actuator is engaged to said each rear end of the first and second connectors to control a relative rotation of the first and second connectors so as to subsequently either widen or narrow the hollow.
