The invention relates to a conductor support frame for mechanical vibrating deicing of a four-bundle conductor, which comprises an icebreaking head and a clamping part. The clamping part comprises a mounting table, a left supporting part, a right supporting part and a middle supporting part of an inverse trangle structure. One end of the middle supporting part is connected with the mounting table, while the other end thereof is connected with the left and right supporting parts. The left supporting part is provided with a No.1 connection part and a No.3 connection part. The right supporting part is provided with a No.2 connection part and a No.4 connection part. The left supporting part comprises the No.1 connection part, a left connecting piece and the No.3 connection part. The right supporting part comprises the No.2 connection part, a right connecting piece and the No.4 connection part. The No.1 connection part and the No.3 connection part are symmetrically arranged. The No.2 connection part and the No.4 connection part are symmetrically arranged. The No.1, No.2, No.3 and No.4 connection parts are respectively provided with a connection groove. The conductor support frame not only has simple structure and firm clamping, but also has better deicing effect and higher deicing efficiency.
