The present invention is a chain clasp system with double-layer tracks and double-chains in a plastic film stretching production line. Each side has two upper and lower layers of the same track and two upper and lower identical chains. Seat, upper (lower) track is positioned between upper (lower) support plate and middle support plate, and upper (lower) support plate (lower) side fixes 2 chain links of upper (lower) layer chain. One upper (lower) middle inner bearing and one upper (lower) middle and outer bearing are fixed on the (lower) side of the middle support plate. Two upper (lower) outer bearings are fixed on the lower (upper) side of the upper (lower) support plate. Each bearing is tangent to the side surface of the upper (lower) track respectively. The distance between the plane where the sandwich opening is located and the horizontal mid-section plane of the middle support plate is less than 5mm. The top end bearing above the upper support plate is tangent to the top surface of the upper track. During operation, the upper and lower chains drive the chain clips, and the tension of the thick film is distributed on the upper and lower tracks through the bearings, which increases the stress on the force-bearing surface and makes the parts less prone to deformation and damage, ensuring reliable operation.
