To orgnaization of clamp of domestic and international hinge the design undertakes analysis and more knowable, orgnaization of certain hinge clamp appears " ability of oil cylinder job is restrained " , " time of executive lever clamp and convert of loose time scale " wait for passive situation, because the friend that chooses the design stage that oil cylinder cannot ignore this relative to the position correctly was omited in orgnaization design,be completely. If pursue,1 is shown. When the pressure oil that is P for F, pressure when discharge enters oil cylinder from J mouth, workpiece of executive lever clamp, the oil cylinder output to hinge B force, Q of drawing pulling force can convey 　 　 　 by next type (1) the D in type and D reach piston shank diameter for the diameter inside oil cylinder respectively. Graph 1 　 because type (1) what showing output strength is oil cylinder only inherent ability -- one part, because the ability of the oil cylinder when this clamp did not get sufficient play. Additional, set a piston right now right (or towards the left) floating rate is VJ (or VK) , can list according to fluid drive principle the scale of VJ and VK is like 　 of 　 of 　 issueing 　 (2) 　 because the piston is right move reach left moving route is same, and think approximately maintain divide evenly from beginning to end in the piston in the journey that reachs towards the left right fast shift, because this can get 　 of 　 　 　 (3) the TC in type and TD reach loose time for clamp, x0 is the single stroke of the piston. Type (3) make clear: TC ＜ TD, when clamp appear more easily the phenomenon that executive lever bumps workpiece. The graph is shown 2 times is workpiece of clamp of executive lever of the orgnaization when pressure oil enters oil cylinder from K mouth, so oil cylinder is to the output force of B hinge turn pressure. Set a plan when 2 orgnaizations carry out clamp, oil cylinder is right of B hinge push pressure to be T0C, loose time to be T0D, orgnaization for time of Q, clamp other parameter pursues together 1. Not hard analysis gets T0D of ＞ of T0C of 　 of 　 of 　 of Q0 ＞ Q to pursue 2 　 this that is to say, the graph shows hinge clamp orgnaization 2 times apparent excel graph shows an orgnaization 1 times.
