Since the form as shown in FIG. 3 is different in the opening / closing direction of the spacer 4 with respect to the swing frame plate 7 and the inserting / removing direction of the pin for positioning them, the swing frame is utilized by the opening / closing operation of the spacer 4. Since the plate 7 and the spacer 4 cannot be positioned, it is necessary to manually insert and remove the positioning pin. Further, since the inserting / extracting direction of the positioning pin differs from the opening / closing direction of the spacer 4 by nearly 90 degrees, the inserting / extracting stroke of the positioning pin cannot be increased, and the taper angle of the positioning pin also becomes large. It becomes difficult to achieve contact and contact at the same time.

As described above, according to the formwork of the present invention, even if the opening / closing direction of two members to be fastened / separated and the fitting / removing direction of the positioning fitting pair are different, the fitting pair is fitted. The disengagement and the mutual fastening of the members to be fastened and the release of the fastened members can be performed from the outside of the formwork in one operation, and it is not necessary for an operator to enter the formwork for positioning, so that workability and work safety are improved. . In addition, if a toggle link type is used as a device for fastening two members to be fastened and separated and a tapered hole and a tapered pin are used as a fitting pair, a plurality of fastening devices arranged along the rotation axis can be obtained. It can be operated in one operation and the structure is simple.
