[0002] A flexible connection is used between the circuit breaker and the busbar. The flexible connection is a copper flexible connection that is evenly arranged around the busbar axis and has the function of connecting and fixing the busbar. When the circuit breaker is overhauled, the flexible connection between the circuit breaker and the busbar needs to be disconnected. After disconnection, there is a risk of the busbar falling due to the lack of fixed support. Therefore, a support frame is usually installed at the bottom of the circuit breaker housing during maintenance, and an auxiliary bracket is further installed on the support frame to support the busbar; however, this support method has the following defects:

The support rod 7 is in a horizontal state when in use, and the top plate 9 on the support rod 7 contacts the bottom end of the busbar 1 to determine the position of the busbar 1 and limit the position.

[0031] Preferably, the support plate 5 is connected to the circuit breaker housing 4 by two bolts. The support plate 5 is locked on the circuit breaker housing 4 by two bolts. When in use, one of the bolts is removed, the other bolt is loosened, the support plate 5 is rotated to just below the busbar 1, and the support plate 5 is locked by the two bolts.
