Street lamp manufacturing welding machine

The invention relates to the technical field of street lamp manufacturing, in particular to a street lamp manufacturing welding machine which comprises a base body, a first telescopic part is arranged on the outer wall of the base body, a lifting plate is arranged at the telescopic end of the first telescopic part, a supporting plate is arranged on the outer wall of the lifting plate, and a mounting plate is arranged at the end of the supporting plate. And movable openings are formed in the outer walls of the mounting plate and the lifting plate correspondingly, sliding rods are fixedly arranged in the movable openings, movable blocks are movably arranged on the outer sides of the sliding rods, and grooves distributed at equal intervals are formed in the outer walls of the movable blocks. The gap formed between the abutting plates is adjusted to be consistent with the bending radian of the lamp arm, so that when the abutting plates clamp the lamp arm, the stability of the lamp arm can be guaranteed, meanwhile
