摘要： The present invention relates to a quick clamping device. A pressing flange and a top plate are respectively installed on both sides of a bracket; one end of a top rod is rotatably connected with the top plate, and the other end is in threaded connection with a center pressing element; a slip ring copper sleeve is sleeved on the center pressing element; a synchronous slip ring can be sleeved outside the slip ring copper sleeve relatively movably; the outer end part of the slip ring copper sleeve is provided with a copper sleeve flange; a spring sleeved on the slip ring copper sleeve is arranged between the synchronous slip ring and the copper sleeve flange; both ends of the spring are respectively abutted against the synchronous slip ring and the copper sleeve flange; a plurality of pull rods are evenly distributed along the circumferential direction of a clamped element; one end of each of the pull rods is respectively hinged to the center pressing element, and the other end is a pressing end; the clamped element is positioned between the pressing flange and the pressing end of each pull rod; a connecting rod is connected between each of the pull rods and the synchronous slip ring; and both ends of the connecting rod are respectively hinged with the pull rods and the synchronous slip ring. The present invention has the advantages of novel structure, simple operation, small size, and the like.
