Novel clamp for welding metal packaging box accessories

The invention provides a novel clamp for welding metal packaging box accessories. The novel clamp is reasonable in design, high in working efficiency and convenient to use. The clamp comprises a fixed base, wherein a sliding rail is arranged on the fixed base; two parallel vertical clamps are arranged on the sliding rail side by side; an adjusting bolt capable of adjusting tightness degree of the clamp is arranged at the bottom of each vertical clamp. According to the novel clamp for welding metal packaging box accessories, the two vertical clamps are completely arranged in parallel; during use, a balancing shaft head with a welded I-shaped joint is firstly used for vertically clamping the I-shaped joint by one vertical clamp, then the other to-be-welded I-shaped joint is vertically clamped by the other vertical clamp, then the welding operation is carried out, so that the I-shaped joints at two ends of the balancing shaft head are completely located on the same horizontal line; the welding accuracy is greatly improved; the novel clamp for welding metal packaging box accessories is simple and reliable in overall structure, skillful in design and low in production cost, and is suitable for large-scale popularization and application.
