Clamping device for cutting multilayer filter cloth

The invention discloses a clamping device for cutting a multilayer filter cloth. The clamping device comprises a fixed seat, two symmetrical cavities are formed in the fixed seat, and a first slidinghole is formed in the inner top wall of each first cavity; second cavities are formed in the left and right ends of the fixed seat correspondingly; a first bearing is fixedly inlaid on the inner sidewall, close to each first cavity, of the corresponding second cavity; and forward and reverse rotating motors are fixedly connected to the inner side walls, away from each other, of the two second cavities. According to the clamping device for cutting the multilayer filter cloth, by arranging the forward and reverse rotating motors and by cooperatively using of threaded rods, threaded pipes, powerful springs, electric pushing rods and a second fixing plate, the threaded rods can be effectively driven to rotate through rotation of the forward and reverse rotating motors, the threaded rods rotate to drive connecting rods
