Property piece wind the multi-turn to be formed and often enclose between be mutually adjacent to, the scroll portion of profile generally hollow cylindrical and by scroll portion most
Outer layer metal piece extends one section of a stretching end, is mainly used in all kinds of bascule such as up and down balance systems for requiring constant force output and fills
Put, carbon brush for electric machine spring etc..Its feature is that the spring tension of output is more constant, and tension variations are minimum.When actual use all
It is directly to open constant force spring stretching to make straight-line displacement campaign, and fixed force spring is exported constant thrust.
And be different in the weight of different vendor and the display of different size, thus, it is desirable to manufacture different perseverances
Determine the lowering or hoisting gear of thrust to support, i.e., the same power of setting lowering or hoisting gear can not meet different size display lift adjustment
Demand, the versatility thereby resulted between different displays is poor, thereby results in production cost lifting, and when more switching display
Its support means must be changed simultaneously, that is, causes certain energy waste.
