Production clamp of circuit board

The utility model discloses a circuit board production clamp which comprises a support, a rotating rod and an electric telescopic rod are rotationally connected to the two opposite sides of the support respectively, clamps are fixed to the opposite ends of the rotating rod and the electric telescopic rod, and a first driving motor fixed to the rotating rod is fixed to one side of the support. The outer walls of the rotating rod and the electric telescopic rod are sleeved with collision rods; according to the scheme, the distance between the two clamps is adjusted under the movement of an electric telescopic rod, a circuit board can be clamped and fixed through the clamps, after one face of the circuit board is welded, the circuit board is driven to rotate and turned over under the movement of a first driving motor, meanwhile, a collision plate is extruded in the synchronous rotation of a collision rod, and therefore the circuit board is welded. When the circuit board is welded, the collision plate extrudes th
