Beneficial Effects

[0011] The utility model provides a manual operating mechanism with protection for an isolating switch. Compared with the prior art, it has the following beneficial effects:

[0012] 1. The isolating switch uses a manual operating mechanism with protection. By setting an external protection mechanism, hold the handshake and rotate the handshake. The handshake rotates with the rotating plate. The rotating plate pulls the first pull rope, the first pull rope pulls the card block, and then pulls the handshake, so that the protective tube and the fixed ring are separated, and then the operating rod is rotated. The operating rod rotates with the transmission rod through the gear. The rotation of the transmission rod makes the transmission mechanism of the isolating switch work, so that the isolating switch is opened and closed. After the operation is completed, the protective tube is inserted into the outside of the fixed ring, and the card block is inserted into the inside of the card hole. Then use a lock to lock the fixing plate and the L-shaped plate to prevent external personnel from removing them. In this way, the protective tube can protect the operating rod and reduce exposure to the outside and erosion by rain.

[0013] 2. The isolating switch uses a protected manual operating mechanism. By setting an insulating protection mechanism, the pressure block is pressed, and the pressure block pulls the second pull rope. The second pull rope pulls the movable plate to move, so that the ratchet of the movable plate and the ratchet of the socket are separated, and then the two clamping rings are separated, and then the insulating rubber sleeve is removed and replaced with a new insulating rubber sleeve. Then the two clamping rings are closed, and the fixed frame is inserted into the inside of the socket. The ratchet is blocked, and the clamping ring clamps the insulating rubber sleeve and fixes the insulating rubber sleeve. This makes it convenient to replace the insulating rubber sleeve and prevents the insulating rubber sleeve from being damaged, which increases the risk of the staff.
