The left circular arc-shaped pressing plate 40a and the right circular arc-shaped pressing plate 40b are identical in construction and are plates having an arc shape. Two support plates 42a are welded at a certain distance at the center of the outwardly convex surface of the left circular arc-shaped presser plate 40 a. The two support plates 42a are each formed with a through hole, and the through holes have the same center line. Two support plates 42b are welded at a certain distance from the center of the outwardly convex surface of the right circular arc-shaped presser plate 40 b. The two support plates 42b are each formed with a through hole, and the through holes have the same center line. Both ends of a left circular arc-shaped pressing plate handle 43a are welded to the outwardly protruding surfaces of the left circular arc-shaped pressing plate 40a, respectively, on both sides of the two supporting plates 42 a. Both ends of a right circular arc-shaped pressing plate handle 43b are welded to the outwardly convex surfaces of the right circular arc-shaped pressing plate 40b, respectively, on both sides of the two supporting plates 42 b.
