Clamping, pulling and returning mechanism for large-length-diameter-ratio rubber ring finished product

The invention provides a clamping, pulling and returning mechanism for a large-length-diameter-ratio rubber ring finished product. The clamping, pulling and returning mechanism for the large-length-diameter-ratio rubber ring finished product comprises a support, a sliding rod, a sliding rail, a fixed claw, a movable base, a movable air cylinder, an auxiliary telescopic rod, an auxiliary support and two starting switch valves. According to the clamping, pulling and returning mechanism for the large-length-diameter-ratio rubber ring finished product, the support, the sliding rod, the sliding rail, the fixed claw, the movable base, the movable air cylinder, the auxiliary telescopic rod, the auxiliary support and a rubber ring fixing rod are arranged and cooperate with one another; and the clamping, pulling and returning mechanism has a folding deformation function, when a person needs to detach and pull out a rubber ring on the rubber ring fixing rod, the overall length of the rubber ring fixing rod is shortened
