[0024] A protective cover 5 is fixedly connected to the upper surface of the mounting plate 2. When clamped, the protective cover 5 is located in front of the flange welding position. An opening 6 is provided on the surface of the protective cover 5. When clamped, the opening 6 accommodates the welding end of the welding equipment. The protective cover 5 is made of a transparent material, and the opening 6 is in an inclined state. The protective cover 5 prevents welding slag from injuring the staff, and the inclined opening 6 provides space for the welding end of the welding equipment to swing left and right, so that the staff can change the welding angle conveniently.

[0025] The left and right ends of the lower surface of the protective cover 5 are fixedly connected with support rods 7, and the lower surface of the support rod 7 is in close contact with the clamp 1. The support rod 7 provides support force for the protective cover 5 to improve the bearing capacity of the adjustment mechanism 3. A multi-functional joint 8 is provided at the installation node of the support rod 7 and the protective cover 5. The upper and lower ends of the multi-functional joint 8 are respectively fixedly connected to the protective cover 5 and the support rod 7.
