The cylindrical shell periphery of concave-convex location lid has recessed breach, is that the cylindrical shell periphery becomes concave-convex, so that arc tensioning frame or tensioning casket insert installation from recessed breach.

It is the rectangle spring of rectangle that the cross section is installed in the casket of tensioning casket, and its end is fixed in the tensioning casket, and end protrudes outside the tensioning casket in addition, and is inserted on the cylinder of the fixing spring on the locking device skeleton jackshaft.

The utility model is through using proof, during the operation flange positioner, can change the arc tensioning frame or the tensioning casket of locking device quickly and easily according to the flange of different size, from but the locking device of flange positioner with the flange that adapts to certain limit and the installation needs of pipeline, and needn't change integral locking device or flange positioner, and use arc tensioning frame or tensioning casket simple light quick again, save time and the labour, this structure is practical, the efficient height.
