The slider 4 is symmetrically provided with two strip-shaped sliding openings corresponding to the toggle rods 13, and the two connecting rods 7 are L-shaped. The ends of the two connecting rods 7 away from the slider 4 are fixedly connected with the clamping plate 8, which is locked with the clamping plate 14 by the locking bolt 15.

After welding is completed, only the locking bolt 15 needs to be rotated to loosen the clamping of the clamping plate 14, and the fixing plate 2 can be removed to avoid the fixing plate 2 hindering the subsequent connection of the flange 1.
