[0006] Preferably, a tenon portion is provided at the connection between the positioning plate and the limiting plate, and a mortise and tenon hole is provided on the limiting plate. The positioning plate and the limiting plate are plugged in and then fixed by welding.

[0007] Preferably, there are three limit plates, which are distributed on two sides of the outer sealing plate of the oil tank.

[0008] Preferably, the positioning plate is provided with a plurality of hollowed-out grooves for reducing the weight of the positioning plate and saving materials.

[0009] Compared with the prior art, the beneficial effects of the utility model are: the production cycle of the utility model is very short, it can be completed half an hour after the design is completed, it is convenient and fast, the structure is simple and practical, and one tool can spot weld workpieces of different shapes in different positions at the same time, which greatly shortens the welding time and improves production efficiency.
