Abstract
The utility model provides a parallel clamp with parallel clamping surfaces. With the adoption of the geometrical theory that two opposite sides of a rectangle are parallel, two diagonal lines of the rectangle correspond to clamp handles (B1 and B2), the cross point of the two diagonal lines corresponds to the central rotating shaft (Io), and a set of opposite sides respectively positioned on two sides of the diagonal lines correspond to clamp mouths (A1 and A2); four contact points between the clamp mouths and the clamp handles are designed with tracks (C1 and C2), sliding blocks (H1 and H2) and two rotating shafts (I1 and I2), and the thickness of the clamp mouths is designed according to needs. The clamp handles (B1 and B2) corresponding to the two diagonal lines of the rectangle are operated to change the distance of the opening clamp mouths (A1 and A2) corresponding to one set of the opposite sides so as to clamp and release an object with a shape of cuboid, cylinder or sphere by the clamp.
