Abstract

The invention discloses a multifunctional operating handle of an earthing knife switch. The multifunctional operating handle comprises a connection rod, a fixing shaft is installed on one side of the lower portion of the connection rod, a fixing tube is installed on the fixing shaft, a connection shaft is installed on the upper portion of the connection rod, a fixing rod is installed on one side of the connection shaft, a fixing groove is formed in one side of the fixing rod, and a spring and a fixed ball are installed in the fixing groove. By means of the multifunctional operating handle of the earthing knife switch, different earthing knife switch sleeves can be quickly replaced; by means of matching of a connection groove and the fixing rod, the sleeve can be fixed, and when one sleeve needs to be replaced, what is needed is to separate the connection groove from the fixing rod, and then the sleeve can be detached. The fixed ball is matched with an arc-shaped groove, then the sleeve can be prevented from slipping off, and the fixed ball can be tightly connected with the arc-shaped groove by the spring.
