The invention discloses a crystal end dismounting tool comprising a handle and two dismounting arms. One end of each of two dismounting arms is fixedly connected with the end part of the handle, and the two dismounting arms are used to form an included angle on the convergence part of the handle, and the two dismounting arms are the two sides of the included angle. The end parts of the dismountingarms are provided with two oppositely-arranged square clamping discs. By using the crystal end dismounting tool, a problem that maintenance personnel cannot pull out network cables by using fingers under a dense arrangement condition is solved, and at the same time, maintenance efficiency is improved, other network cables cannot be touched, and network safety can be improved.
