螺絲頭上放雙面膠帶、無紡布之類的東西。如果沒有條件，也可以用紙，可以增加摩擦力!在螺孔中填充少量502膠，然后擰入螺。膠水凝固后，用尖嘴鉗擰出(不使用螺刀的原因是螺打滑)。只有膠水完全變硬了。(這個操作難度大的時候要小心。)如果螺帽外露，可以用尖嘴鉗夾住螺帽，擰下螺。 也可以切掉螺帽，拆開外殼再處理。一般手機的螺是金屬的，外殼是塑料的。當無法擰開時，可以將尖頭焊頭插入螺帽，加熱金屬螺使螺周圍的塑料熔化，用尖嘴鉗夾住，輕輕拔出!也可以用力向下壓螺1毫米左右(小心別把機殼搞穿)，就可以螺松動的問題了(沒實驗過,網(wǎng)上看到的!)
Put double-sided tape, non-woven fabric and other things on the screw head. If there are no conditions, you can also use paper to increase friction! Fill a small amount of 502 glue in the screw hole, and then screw in the screw. After the glue solidifies, screw it out with pointed nose pliers (the reason why the screw knife is not used is that the screw slips). Only the glue has completely hardened（ Be careful when this operation is difficult.) If the nut is exposed, clamp the nut with pointed nose pliers and unscrew the nut. You can also cut off the nut and disassemble the shell for further treatment. Generally, the screw of mobile phone is metal and the shell is plastic. When it cannot be unscrewed, insert the pointed welding head into the nut, heat the metal screw to melt the plastic around the screw, clamp it with pointed nose pliers and gently pull it out! You can also press the screw down by about 1mm (be careful not to break through the casing), which can solve the problem of loose screw (no experiment, I saw it on the Internet!)
那么小的螺的確不好弄,(修自行車螺的方法)用小電鉆在弄花的螺正中打一個不深的孔，然后找一個反絲的絲錐擰進去(一定要反絲絲錐，很難找，要去大的量具刃具店)，就可以擰開了用電鉆反螺鉆掉吧.把螺刀的頭部分在煤氣灶上燒紅,然后迅速頂在那個螺上,略等5秒左右,這樣就可以擰出來了
It's really difficult to get such a small screw. (the method of repairing bicycle screw) use a small electric drill to make a small hole in the middle of the flower screw, and then find a reverse screw tap to screw it in (it must be a reverse screw tap, which is difficult to find. Go to a large measuring tool and cutting tool store), you can unscrew it, and use an electric drill to drill it off. Burn the head of the screw knife on the gas stove red, and then quickly push it on the screw, Wait about 5 seconds so you can screw it out
用
扭剪扳手的電烙鐵加熱后放在花掉的螺頭上時間不要太久，直到能擰動螺為止，先可以找一些廢品練習一下手感，這樣拆保險平口螺刀磨出刃，開始擰。。。。
After heating with an electric soldering iron, put it on the spent screw head for a short time until the screw can be screwed. First, find some waste products to practice the feel. In this way, remove the safety flat mouth screw knife, grind out the blade and start screwing....
融化的焊錫掛在焊槍頭上,將螺刀和螺釘對好后,將焊錫點上去，降溫開擰用鉆頭將鑼帽打掉。利用反絲的原理將剩余的螺鉆出(可以用斷頭螺專用鉆頭--斷頭螺取出器)
Hang the melted solder on the head of the welding gun, align the screw cutter and screw, spot the solder, cool down and turn it on, and knock off the Gong cap with a drill bit. Use the principle of reverse thread to drill out the remaining screws (you can use the special drill bit for broken screw - broken screw extractor)
告訴我一個方法:用烙鐵把滑動螺絲上的焊料燒了，然后把螺刀粘在上面，等焊料干了再旋轉(zhuǎn)。我的螺釘很滑，所以我做了幾次才成功。老人告訴我，正常情況下，可以一次擰開。新發(fā)現(xiàn)用刀反復刻螺，直到十字螺刻成直螺，然后就可以拆了。
Tell me a way: burn the solder on the sliding screw with a soldering iron, then stick the screwdriver on it, and rotate it when the solder is dry. My screw is slippery, so I did it several times. The old man told me that under normal circumstances, it can be unscrewed at one time. The new discovery repeatedly carves the screw with a knife until the cross screw is carved into a straight screw, and then it can be removed.
