A stitch tightening device of a ball stitching machine comprises a ball stitching table having at least one clamping tool and a stitch tightening unit for tightening a thread to be assembled to a ball. The stitch tightening unit includes a set of thread clamping units at two sides of the clamping tool. The stitch control device is interconnected with and interacted with a first treadle through a driven element; and the stitch tightening unit has at least two clampers; the first treadle drives a control wire; and then the control wire drives the clamper so as to engage the thread clamping unit. The clamping head is connected to a second treadle through a linkage; and the second treadle drives the clamping head to move aside to be away from the stitch control device. The first treadle drives a control wire through a driven element.
