A vise comprises a main seat, two movable jaws, two transmission blocks, a control rod, and a fixing jaw mounted detachably on the main seat to form together with the two movable jaws the double clamping seat. The control rod is provided with a tolerance compensating device comprising: a sleeve fitted over the control rod and fastened to the main seat; two end thrust members mounted on the control rod and located at both ends of the sleeve; and at least one elastic element located between the sleeve and the control rod for providing a resistance preventing the control rod to move axially. The double clamping seat can be converted into the single clamping seat by removing the fixing jaw from the main seat. The tolerance compensating device and the control rod are provided therebetween a fastening device regulating the control rod to turn without moving axially.
