Claims

[Claims for Utility Model Registration] 1. A cylindrical opening raising tool connectable to the lid mounting groove 3a of the lid mounting frame 3 located at the opening periphery 1a of the processing tank 1; It is composed of two types of opening extension tubes 6A and 6B, which have different diameters D ₁ and D ₂ within the width L of the lid mounting groove 3a, and which can be inserted into and removed from each other from the axis of the tube. A tool for raising the opening of a processing tank, in which at least one end of each of extension tubes 6A and 6B constitutes an attachment part for a ring 7 provided with a groove 7a for attaching a lid. 2. The opening extension tubes 6A, 6B are formed with reinforcing ribs 6a and cutting ribs 6b alternately spaced apart from each other by a predetermined pitch in the axial direction of the tubes.
The treatment tank opening raising tool described above. 3 Among the double-opening extension tubes 6A and 6B, the dimensional difference 1 between the outer circumferential surface of the small-diameter open extension tube 6B and the inner circumferential surface of the large-diameter open extension tube 6A is the same as that of the connecting portion 7b of the ring 7. The processing tank opening raising tool according to claim 1 or 2, which is configured to be slightly larger than the thickness.
