It can realize clamping and unclamping fast, and can guarantee to clamp the intensity of strength. In this way it can avoid such situation that when clamping a thin part in the past, the time go to the mode cannot confirm, and can make clamping and unclamping fast at the same time , so can improve production efficiency in a high intensity.In order to make clamping and unclamping fast, make the traditional whorl into hydraulic transmission, the fixation of the activity pincers depend on embracing activity pincers body firmly through frictional force comes by the brake handle driving steel band brake lump. That realizes the fast movement of the activity pincers body, while clamped strength guaranteed by clamping the spring. We can guarantee to clamp the intensity of strength by adjusting the tight intensity of the spring.Compared with traditional whorl bench vice, the hydraulic bench vice has weak point. The first is more expensive than the traditional bench vice on the cost, and it is a little more complicated in manufacture and operation. The second, the strength direction of hydraulic bench vice is limited, greater strength (such as shock power ) can only be in the body direction of the fixed pincers , bring inconvenience to operator. These weak points are still should be improved, and diligent is needed in this Vdirection later.Key words: Hydraulic transmission; Transmission of the whorl; Clamp strength
