一天,我看到爸爸在钉钉子,因为钉子小很难捏住,爸爸好几次都把钉子钉歪了,有一次锤子还砸在了手上,起了一个大大的紫泡。怎样才能既不让钉子钉歪又不伤到手呢?经过一番研究,我发明了钉子扶助器。取两根钢筋制成剪刀的形状, 在钢筋两边对应的位置打若干个半圆形缺口,然后在缺口内粘上薄海绵,以增加摩擦力,并将钢筋两端分别设计成十字螺丝刀和平口螺丝刀。使用时,用扶助器把钉子(或螺丝)夹住,就不容易钉歪了,也不会伤到手,而且扶助器还可以当螺丝刀用。
One day, I saw my father nailed his nail because the nail was hard to pinch. His father crooked the nail several times. Once again, the hammer smashed into his hand and played a big purple bubble. How can we not let the nail crooked without hurting the hand? After some research, I invented the nail assistive device. Take two steel made of scissors shape, in the corresponding position on both sides of the rebar to play a number of semi-circular notch, and then stuck in the gap thin sponge to increase friction, and both ends of the reinforcement were designed as Phillips screwdriver and flat mouth screwdriver. Use, with the help of nail (or screw) grip, it is not easy to nail crooked, it will not hurt the hand, but can also be used as a screwdriver.
