In order to achieve rapid clamping and loosen, the traditional thread into hydraulic transmission, activities of the body is fixed by clamp brake handle to drive the steel with brake block through the friction will carry death activities, so as to realize the activities and clamp and the fast moving, clamp and clamping force by the clamping spring to ensure that, we can adjust the spring tension level to ensure that the size of the clamping force. Hydraulic machine with the traditional thread a jaw jaw or some disadvantages compared. One is better than the traditional in the cost to expensive, and relatively speaking, manufacturing complex, the operation is more complicated; 2 it is the stress of the jaw hydraulic sets the direction is restricted, greater force (such as the impact) can only be fixed clamp body direction, to bring inconvenience operator.
