Spraying jig for surface coating of stamping rod

The utility model relates to the technical field of spraying jigs, in particular to a spraying jig for a surface coating of a stamping rod. The device comprises a base, an anti-sputtering device and a fixing cylinder are arranged on the upper surface of the base, an elastic piece is fixedly connected to the arc surface of the fixing cylinder, a convenient device is arranged on the lower surface of the base, and the anti-sputtering device comprises a corrugated pipe fixedly connected to the upper surface of the base. A plurality of identical fixing blocks are fixedly connected to one side of the outer surface of the corrugated pipe, a first round pipe is rotatably connected to the surface of the fixing block at the corner, a second round pipe is rotatably connected to the surface of the fixing block at the upper portion, and the second round pipe slides in the first round pipe. The problems that sprayed spraying materials penetrate through a punching rod and then are sputtered to other places to cause pollutio
