随着学校计算机教育的普及和发展,机械式鼠标也相继进入了学校。但使用一段时间后,往往会有失灵现象。因为鼠标内部机械结构简单,可以自己动手修复。如果仅是单、双击不灵,则多半是鼠标按键下的那个微动开关内部接触不好。这时,可将外壳打开,滴入两滴95%的酒精或用“精密电器清洁剂”喷一下,然后用手按几下。如仍无效,应换上一个同型号的微动开关。如果移动鼠标有阻滞感,屏幕上的鼠标箭头也不灵。这时可将外壳打开倒出橡皮小球,观察小球与橡皮小球联动的两极互相垂直的传动杆以及用来稳定橡皮球的小轮等三个部件的表面是否清洁。若有污迹,可用光滑的小木片擦去(或刮去),再用酒精棉球清洗。若它们都还干净,再把整个底 With the popularization and development of computer education in schools, mechanical mice have also entered schools one after another. However, after using it for a period of time, there will often be failures. Because the mouse internal mechanical structure is simple, you can repair it yourself. If only a single, double-click is not working, then most of the mouse button that micro-switch internal contact is not good. At this time, you can open the shell, drip two drops of 95% alcohol or “precision electrical cleaner” spray a bit, and then by hand a few times. If still invalid, should be replaced by a same type of micro switch. If you move the mouse has a sense of block, the mouse arrow on the screen is not working. At this time, the shell can be opened and poured out of the rubber ball to observe whether the surface of the three components such as the transmission rod that is perpendicular to the two poles and the small wheel that is used to stabilize the rubber ball are clean. If smudges, use a smooth small piece of wood wipe (or scraping), then alcohol cotton ball cleaning. If they are still clean, then the bottom
