The present invention discloses a wire fixing frame, which comprises a carriage horizontally arranged on one side of an electric pole. The outer end portion of the carriage is provided with a supporting member matched with a wire. A bracing frame is connected between the bottom of the carriage and the electric pole. During the assembly and usage process, the carriage is fixed onto the electric pole and then the wire is overlapped onto the supporting member. The supporting member supplies a sufficient supporting force for supporting the wire. Meanwhile, the bracing frame supplies a sufficient supporting force for supporting the overall structure of the carriage. Therefore, the overall structure of the wire fixing frame is ensured to be stable and reliable. Moreover, the supporting reliability and the supporting stability of the wire fixing frame for wires can be effectively ensured.
