Abstract
A connector for connecting a tank truck to an underground oil depot has a body, a handle, a transmission device and two locking arms. The body has a mounting tube and a connection tube respectively connected with an oil drain valve and an oil pipe. The handle is pivotally mounted on the body. The transmission device is pivotally connected to the handle and has a linking lever and two transmitting levers. The linking lever is pivotally connected to the handle, and the transmitting levers are pivotally and slidably connected to the linking lever. The locking arms are pivotally mounted on the mounting tube of the body, selectively extend into the mounting tube and are respectively connected securely to the transmitting levers. Each locking arm has a pushing protrusion mounted on the locking arm and is adapted to push against a joint on the oil drain valve.
