1. A vise comprising:
a groove-shaped vise body including two grooves on inner surfaces of two sides respectively;
an internally threaded first sliding member including a concave surface, the first sliding members being configured to slide with respect to the vise body by sliding along the grooves;
an internally threaded second sliding member including a concave surface, the second sliding members being configured to slide with respect to the vise body by sliding along the grooves;
a fixed jaw secured to a top of an intermediate portion of the vise body;
a first movable jaw put on the first sliding member, the first movable jaw including a rod member disposed between the concave surface of the first sliding member and an inner surface of the first movable jaw;
a second movable jaw put on the second sliding member, the second movable jaw including a rod member disposed between the concave surface of the second sliding member and an inner surface of the second movable jaw;
a fastening device secured to the vise body and adjacent to the first movable jaw, the fastening device including a rotatable shaft;
an actuation assembly disposed in the vise body, the actuation assembly including a hollow first threaded shaft passing through and threadedly secured to the first sliding member, the first threaded shaft secured to the fastening device, a hollow second threaded shaft passing through the second sliding member and threadedly secured to the second sliding member, a first movable rod disposed in the first threaded shaft and secured to the rotatable shaft, a second movable rod disposed in the second threaded shaft, and a pushing rod engaging the first movable rod, the pushing rod having an inclined surface distal the first movable rod; and
a force transmitting assembly disposed between the first threaded shaft and the second threaded shaft and under the fixed jaw, the force transmitting assembly including a hollow cylindrical housing secured to the first threaded shaft, a hollow activation member disposed in the housing and having two opposite troughs, a positioning member disposed in the housing and having two opposite troughs, two toggle joints each having a first end pivotaby disposed in one of the troughs of the positioning member, and a second end pivotably disposed in one of the troughs of the activation member, a spring-biased member disposed in the activation member and engaging the pushing rod, a biasing member put on the second movable rod and anchored between the second movable rod and the second threaded shaft, a ring member put on the activation member and biased between the biasing member and the activation member, and a resilient ring put on the pushing rod and biased between the activation member and the first threaded shaft;
whereby upon clockwise rotating the rotatable shaft, the first threaded shaft is rotated causing the first sliding member to move the first movable jaw toward the fixed jaw, compress the resilient ring, push the first movable rod to move the pushing rod which in turn straightens the toggle joints, push the housing toward the second movable jaw by compressing the biasing member, push the second movable rod to rotate the second threaded shaft which in turn moves the second sliding member toward the housing, and move the second movable jaw toward the fixed jaw.
