Novel opening device for jacquard

The invention discloses a novel opening device for a jacquard, which belongs to the technical field of textile machinery. The structure is mainly formed by a spindle transmission mechanism, an eccentric wheel mechanism, a connecting rod mechanism, a swing arm mechanism, a pull rod mechanism, a lifting plate mechanism, a guide mechanism, sliding blocks, griffe supports and the like. By means of vertical swinging of two groups of swing arms and connecting delivery of pull rods with adjustable distances, two groups of lifting plates connected with the opening device are in vertical reciprocation motion, simultaneously each group of griffe supports connected with the opening device are also in vertical motion to form a double action opening, each group of lifting plates are in vertical motion, pulleys on hole positions at the upper ends of the lifting plates slide vertically in two vertical guide mechanisms perpendicular to each other, left and right motion of the lifting plates is restrained, front and back moti
