一般上双头螺丝的方法,是在双头螺丝的尾部旋入两个螺帽,把它们拼紧后,当普通的倒插螺钉,用板手套住上面一个螺帽旋入螺孔中;或者用管子板手夹住颈部,使它旋入螺孔中等等。这些方法虽然简单,但是效率不高。下面是几种比较先进的上双头螺丝的工具。如图1的简单工具,由两个另件组成。在使用时,只要用手把螺套1旋紧在双头螺丝上,再用板手套住螺套1旋转就行了。当双头螺丝旋入螺孔中以
In general, the method of double-headed screws is to screw two nuts into the rear of the double-headed screws. When they are tightened together, the normal inverted screws are screwed into the screw holes with a screwdriver on the board. Clamp the neck with a pipe wrench, screw it into the screw hole, and so on. Although these methods are simple, they are inefficient. Here are some of the more advanced tools on the double-headed screw. The simple tool shown in Figure 1 consists of two parts. In use, as long as the screwdriver 1 hand screwed on the double-headed screw, and then use the plate gloves to rotate the nut 1 on the line. When the double-headed screw into the screw hole
