成盘的钢丝由于弹性较大,一经打开立即散开,既不好保存,又不便使用。为此,笔者设计制作了简易钢丝保护盘,现介绍如下。取软质饮料筒一个,从底部向上3cm处画一条线,在此线上每隔2cm向上剪一个直径2cm的瓣,将瓣向内折转即可(附图)。由于筒的直径与钢丝卷的直径大小相同,筒的底部周围还有一凹陷区,所以正好将钢丝放入。使用时将钢丝的一头拉出即可。这种钢丝保护盘 Into a plate of steel due to greater flexibility, once opened immediately spread, neither good preservation, but also inconvenient to use. To this end, I designed a simple wire protection plate, are presented below. Take a soft drink tube, drawing a line from the bottom up 3cm, in this line every 2cm up to cut a 2cm diameter petals, the flap can be folded inward (photo). Since the diameter of the barrel is the same as the diameter of the coil, there is also a recessed area around the bottom of the barrel, so just put the wire in. Use to pull out one end of the wire.
