ABSTRACT:
A quick clamping type vice in which a chuck and a spring are disposed in a main base seat. The chuck is substantially U-shaped and an inner side of the bottom of the chuck is formed with a semicircular thread facing upward. A cover board is disposed on the upper side of the chuck and locked with the chuck to form an integral body. The spring is disposed right under the chuck. The thread rod passes through the main base seat and ride on the bottom of the chuck. The spring pushed the chuck upward to make the thread of the chuck engaged with the thread rod. When the cover board is depressed, the chuck is vertically moved downward and disengaged from the thread rod. At this time, the thread rod is liberated and can be quickly slided. When releasing the cover board, the spring makes the thread of the chuck again engaged with the thread rod. Accordingly, the clamping and loosening operation of the vice can be quickly performed.
