在中小学实验教学中(如力的平衡,力的测量、电磁感应以及弹簧单摆等实验),经常用到各种不同规格型号的线圈或弹簧。在这里向大家介绍一种能够绕制多种规格弹簧或线圈的两用绕线器,这种绕线器可以绕制φ6、φ8、φ10或其它规格的线圈或弹簧。该绕线器结构简单,操作方便,易于制做,经济实用。现将其结构及操作方法简介如下: In the experimental teaching of primary and secondary schools (such as force balance, force measurement, electromagnetic induction, and spring pendulum experiments), various types of coils or springs are often used. Here, we will introduce a dual-purpose winder capable of winding a variety of springs or coils. The winder can be used to wind φ6, φ8, φ10 or other size coils or springs. The winder has a simple structure, is easy to operate, is easy to manufacture, and is economical and practical. The structure and operation method are summarized as follows:
