The invention discloses a cloth cutting machine which comprises a first support and a second support. The first support is arranged parallel to the second support; connecting shafts are arranged at the two ends of the side, close to the second support, of the first support correspondingly; the first support is connected with the second support through the connecting shafts; the connecting shafts are sleeved with paying-off rollers correspondingly; a first fixation block and a first slide rail are arranged on the side, close to the second support, of the first support; the first fixation block is located on the lower portion of the first slide rail; and a first fixation clamp is arranged on the first fixation block. A second fixation block and a second slide rail are arranged on the side, close to the first support, of the second support; the second fixation block is arranged on the lower portion of the second slide rail; a second fixation clamp is arranged on the side, away from the second support, of the second fixation block; and a slide rod is arranged between the first slide rail and the second slide rail. The cloth cutting machine is simple in structure, convenient to use, free of deformation and small in error. Cloth is cut according to patterns, and succeeding process is facilitated.
