The invention relates to the technical field of vacuum electronic products, and provides a pre-assembling jig for a spiral line and a clamping rod, which comprises a retainer used for containing a spiral line and a clamping rod, a supporting frame used for containing the retainer, and a retaining plate arranged on the supporting frame and used for fixing the clamping rod in a matched mode. According to the pre-assembling jig for a spiral line and a clamping rod, the spiral line and the clamping rod are placed through the retainer, the retainer is fixed to the supporting frame, and then the clamping rod is fixed through the retaining plate matched with the supporting frame, so that the clamping rod and the spiral line can be protected to be relatively static during assembly and movement, and the assembly efficiency and the reliability of finished products are greatly improved.
