[0006] The above technical solution is further limited. The structure of the left articulated arm includes a left pulling arm and a locking arm. The upper end of the left pulling arm is provided with a hanging ring hole. The left pulling arm is connected to the hanging ring. The lower end of the left pulling arm is connected to the upper end of the locking arm through a swivel pin. The inner side surface of the locking arm is fixedly connected to one end of the hanging rod.

[0007] The above technical solution is further limited. The structure of the right articulated arm includes a right pulling arm and a hanging arm. The upper end of the right pulling arm is provided with a hanging ring hole. The right pulling arm is connected to the hanging ring. The lower end of the right pulling arm is connected to the upper end of the hanging arm through a swivel pin. A limiting hole is provided on the inner side surface of the hanging arm, and the other end of the hanging rod can pass through the limiting hole.

[0008] The above technical solution is further improved in that a fixing seat is provided on the right joint arm near the limiting hole, a rubber ring is provided on the fixing seat, an annular groove is provided on the outer circumferential surface of the hanging rod, and one end of the rubber ring is engaged with the annular groove.

[0009] Beneficial effects: The utility model utilizes the reaction force of the balance suspension's own weight to form the left joint arm and the right joint arm into a self-locking whole, thereby stably lifting the balance suspension; the utility model has a simple structure, low manufacturing cost, easy operation, is small and flexible, has a large adjustment range, and can be used for lifting different types of balance suspensions, so as to improve work efficiency during the assembly process and reduce the labor intensity and safety risks of operators.
