When the longitudinal angle of the fusion pipe or the welding gun 3 needs to be adjusted, the longitudinal adjusting screw rod 7 can be rotated clockwise or anticlockwise through a hand wheel. When the longitudinal adjusting screw rod 7 is rotated clockwise through the hand wheel, the ball end of the longitudinal adjusting screw rod 7 moves towards the ball seat, and the ball seat is fixed on the welding machine, so that when the ball seat moves to the limit, the adjusting plate 1 receives a reaction force, at the moment, the upper part of the adjusting plate 1 is inclined towards the direction away from the adjusting seat 2 by taking the hinge bolt 4 as the center, and the lower part is inclined towards the direction close to the adjusting seat 2 by taking the hinge bolt 4 as the center, so that the longitudinal angle adjustment of the fusion tube or the welding gun 3 is realized.

When the transverse angle of the fusion pipe or the welding gun 3 needs to be adjusted, the transverse adjusting screw rod 10 can be rotated clockwise or anticlockwise through a hand wheel. Because the ball seat is fixed on the welding machine through the adjusting seat 2, when the longitudinal adjusting screw rod 7 is rotated clockwise or anticlockwise through the hand wheel and the ball moves to the limit, the adjusting plate 1 can be inclined in the transverse direction by taking the hinge bolt 4 as the center, so that the longitudinal angle adjustment of the fusion tube or the welding gun 3 is realized.
