摘要（英）：

The utility model relates to an operation valve interlocking device of a trolley earthing knife switch. The operation valve interlocking device is characterized by including two parts, namely an inner locking member and an outer locking member, wherein the inner locking member is installed on an operation valve of a trolley earthing knife switch cabinet, and the outer locking member is disposed outside the operation valve of the trolley earthing knife switch cabinet. The operation valve interlocking device has the advantage that the operation valve interlocking device can interlock the operation valve of the earthing knife switch no matter the earthing knife switch is in an opening position or a closing position, thereby preventing accidents caused by misoperation.
