Elastic support unit for wall bushing assembly

The invention relates to an elastic support unit for a wall bushing assembly to solve the problem that a conducting rod is easily damaged due to overlarge pretension force of an elastic support part in the prior art. The elastic support unit for the wall bushing assembly comprises the elastic support part which is used for being elastically supported between a connecting flange fixedly connected with the end part of a wall bushing and a stop structure fixedly connected with the end part of the conducting rod; a first flange structure which is used for being detachably connected with the connecting flange is fixedly arranged at one end of the elastic support part, and a second flange structure which is used for being detachably connected with the stop structure is fixedly arranged at the other end of the elastic support part; an adjusting part for adjusting the pretension force on the stop structure is also arranged between the first flange structure and the second flange structure; andthe acting force applied
