入手的海志的鼠标，十块钱还包邮。用到现在有一年了。我不玩游戏，所以对我已经很好用了。但是现在滚轮老犯别，有时候滑动滚轮会有清晰的摩擦声。今天没事，准备拆开修理它。 
There is a poor mouse buy from Taobao one year ago. It work now but make some noise sometimes when I slide its cycle. Today I fitted it, it is work well now.
只有一个螺丝。弄下来后从屁股撬一下，然后把底朝上往上推一下后盖就下来了。
There has only one screw, you can easy to separate it into two parts after remove this screw.
下来后是这个样子。
This photograph shows that after you separate it.
滚轮很容易就能拿下来，在它 摩擦的地方涂点油就行了。用食用油就行。哈哈。没错，在壳子上发现了秘密。厂家为了增加手感竟然在里面加了块铁！！！我觉得无用啊。直接把它拆下来扔了。
把它再装起来就行了。声音全无而且滑动起来舒服了好多。
It is easy to separate the cycle, then you can take some oil on it.
