Detailed Description

The symmetrical arrangement of high-speed synchronous gear gear: innovation; International standard gear steel, wear-resisting degree doubled than ordinary gourd, turn more smoothly, hand pull more light chain: higher strength of the chain; Counterpart in the welding of fine, medium frequency induction quenching, assistant ISO3007-1984 international standard chain technology requirements; To adapt to the sudden overweight homework; Hand zipper feel better; Alter our common gourd can only vertical down from multiple directions, a 45 ° Angle pulling, adaptation scope is bigger. Hook: high strength material hook, senior alloy material, make outside under overload will not occur when fracture, deformation, only gradually higher safety coefficient; Hook in the new design, make the goods not decoupling.
