V-shaped plate-type tool cathode

The invention relates to a V-shaped plate-type tool cathode. The V-shaped plate-type tool cathode comprises a cathode joint, a cathode cavity, a cavity transition plate, a cathode connecting plate andplate-type cathode bodies sequentially from top to bottom. The cathode cavity is of a tubular structure; the two ends of the cathode cavity are sealed through cavity plugs; the cathode joint is arranged on the upper end face of the cathode cavity, the cavity transition plate is attached to the lower end face of the cathode cavity, and multiple sets of liquid-passing through holes are formed in the cathode cavity and the cavity transition plate; the cathode connecting plate is attached to the lower end face of the cavity transition plate, and a liquid-passing long seam is arranged on the cathode connecting plate; the plate-type cathode bodies are arranged at the lower end of the cathode connecting plate and on the two sides of the liquid-passing long seam correspondingly; and the lower ends of the two plate-type c
