The one vertical part 22 is longer than the other vertical part 23, and nuts 31 and 32 are installed at the tip of both vertical parts. The curing cover body 1 forms a shaft hole 1a capable of rotatably and pivotally supporting the longer vertical part 22. In addition, a plurality of hole parts 1b... are formed on a concentric circle having the longer vertical part 22 used as a rotating shaft and the horizontal part 21 used as a radius, and the shorter vertical part 23 can be inserted into these hole parts.
