ABSTRACT:
An incremental multiple-forced vise of epicyclic gear train type mainly comprises basic components of vise's main body and movable jaw etc. to accommodate a lead screw, two sets ( i.e. double-layer ) of epicyclic gear train and a buffer device. By applying force to the handle and through the buffer device as well as the double-layer epicyclic gear train, it can drive the lead screw to turn, thereby, to make the double hook, movable jaw and jaw plate to move until it touches the workpiece, thereafter, one can keep on applying force to the handle and by using the buffer device and the double layer epicyclic gear train to generate incremental multiple force and transmit the force to the lead screw so as to let the workpiece gain huge incremental multiple clamping force; on the contrary, if one turns the handle in counter-clockwise direction, the incremental multiple-forced function of the double-layer gear train will retreat back to zero in order to release the workpiece, thereby, it is very simple and labour-saving in performing the clamping and releasing operation as well as in creating huge clamping force.
