The course of work of the utility model fast tighten vice is described below in conjunction with Fig. 1:

When this bench vice is in releasing orientation, push-and-pull moving caliper 1 slides vertically fast arbitrarily, touch workpiece to be pressed from both sides until its jaw iron 7, dextrorotation again (Y to) handle 20, screw mandrel 17 just rotates synchronously by means of the effect drive sliding sleeve 11 and the side channel cam 13 of arrangement of clutch, because journey falls in the curve side channel of side channel cam 13, force and roll pin 21 and drive the screw thread that half-nut slide blocks 5 draw close with screw mandrel 17 to the center and tentatively mesh, with screw mandrel 17 be rotated further and fully the engagement, at this moment the curved groove of side channel cam 13 is walked to the end the sixth of the twelve Earthly Branches, side channel cam 13 no longer rotates, when screw mandrel 17 is rotated further, capsule and pill shape pellet shot from a slingshot 12 just can overcome the pressure of spring 3 and deviate from the groove of screw mandrel 17, at the outer surface skid of screw mandrel 17, because the curve cell wall of side channel cam 13 is to rolling the self-locking action of pin 21, half-nut slide block 5 can not unclamp, the Y of screw mandrel 17 just can drive moving caliper 1 to rotation and make J to feed motion like this, forces in caught workpiece.When needs unclamp workpiece, need only be left-handed (Z to) handle 20, make screw mandrel 17Z to rotation, after capsule and pill shape pellet shot from a slingshot 12 falls into the groove of screw mandrel 17, screw mandrel 17 just drives side channel cam 13Z to rotation, at this moment the curved groove of cam 13 is lifts, roll pin 21 and drive half-nut slide blocks 5 and leave the center and be flared to gradually to greatest extent with regard to forcing, at this moment curved groove is gone to another end again, cam 13 just no longer rotates, so capsule and pill shape pellet shot from a slingshot 12 is deviate from the groove of screw mandrel 17 again, just can stop Z to turning handle 20, at this moment bench vice returns to the most loose original state again.

In a word, need only by Y to turning handle 20, just can realize this bench vice from fast to the conversion of (precession) at a slow speed, this moment is by screw mandrel---and the screw thread pair that closed two half-nuts are formed works, as traditional screw mandrel---guide screw matrix bench vice, can realize the clamping of total travel in the scope of jaw maximum opening, it has all functions that traditional bench vice possesses; Be in the state of precession at a slow speed when bench vice, though moving caliper 1 on any position, all can realize from a slow speed to conversion fast (need only Z to turning handle 20, make the screw thread pair inoperative), this be again the traditional slow bench vice can not compare, as long as suitably select the elastic force of spring 3, and by means of distinguishing that pellet shot from a slingshot 12 goes into groove or take off the sound of groove, this bench vice can also possess the function of the certain clamping force of identification.
