1.Material strength of and housing easily uses clean; high density zinc alloy and polishing plating process, high structure strength and easily clean;
2.Adopting a whole new structure of driving wheel, the fit clearance is much smaller;
3.Module design is for tensioner set, self-cleaning vibrating yarn tensioner,magnetic yarn tensioner and spring yarn tensioner can be quick-replaceable;
4.The circuit is two pins & LED, the voltage is adaptive;
5.High precision all closed metal winding wheel and steel winding wheel are optional;
