A locking piece 4 is provided on one side edge of the base plate 1 and stands at an intermediate position. Support pieces 5, 5 are provided upright at the ends and the middle part. 6 extends along the longitudinal direction of the substrate 1;
Further, an operating shaft 7 is movable in the axial direction and rotatably supported by a bearing sleeve provided on the upper part of the support piece 5 at a required distance l from the base plate 1, and 7 is on the lower edge. It has a shaft bearing cylinder 8 which intervenes between the locking piece 4 and the support piece 5 facing it and is allowed to move within a limited range in the axial direction, and the operating shaft 6 is stopped therein. It is an engagement plate that rises and falls with the rotation of the engagement plate.
A restraining piece 9 for restraining the locking plate 3 from above is bent into an L-shape, and when the engaging plate 7 is moved to one restricted end in an upright state, its outer surface will touch the locking piece. 4 and prevents it from falling down. Reference numeral 10 denotes a spring that is interposed between the bearing cylinder and the bearing cylinder 8, and constantly presses the locking plate 7 in the direction in which it comes into contact with the locking piece 4, and constantly presses the engagement plate 7 in the downward direction. Yes, and as a result of the above, the binding member 1
1 is configured. The holding member 12 is attached to a long base plate 13 whose longitudinal side edges are curved downward, and is in contact with the tip of the binding rod 2, and has connecting rods inserted into the binding tubes 3, 3, respectively, at an intermediate position. 14, 14 are installed vertically. 15 is a hole for attachment to the cover, and 16 is a knob.
