When the engagement of the engaging member 13 is released by stepping a push-down turning operation part 132, the fixing support leg 5 is subjected to energizing force of a coil spring 6 to rise to a cylinder 4 and the wheel 73 and take a rising position P2. At this time, the wheel 73 and the foot part 53 of the fixing support leg 5 are positioned within the outer contour of the wheel 73 seen from the side surface.
