The utility model realizes the lubrication between the fixing part and the connecting ring by setting the lubricating mechanism. When the grip handle is operated, the swing of the grip handle drives the sliding rod to swing. The swing of the sliding rod drives the fixing rod to swing under the action of the connecting rod. The swing of the fixing rod drives the connecting ring to rotate around the fixing part. When the connecting ring rotates, it will move the lubricating ball under the action of the annular groove. When the connecting ring presses the lubricating ball, the lubricating tube is opened.
