Novel twin coil book -binding machine clamping ring mechanism spacing device

The utility model provides a novel twin coil book -binding machine clamping ring mechanism spacing device, stop device includes a support, a horizontal pivot, a vertical pivot, a horizontal handle, a vertical handle and two stoppers, wherein, horizontal pivot is connected with the support, and the one end of horizontal pivot runs through one side of support, and be connected with horizontal handle, the stopper is nested mutually with horizontal pivot, the both sides in horizontal pivot are installed to the stopper, and to becoming to distribute, the one end of vertical pivot links to each other with the stopper, the other end links to each other with vertical handle, through rotating vertical handle, make the stopper in the ascending removal of vertical side. The utility model discloses stop device has realized stopper equal realizable function all around, has increased stop device's flexibility, and stopper symmetric distribution has moreover improved the accuracy of coil clamping ring, through the quantity that changes vertical pivot, realize the stopper synchronous with asynchronous removal for stop device's function diversification more.
