这里介绍一种美国产铆钉钳,有直嘴和弯嘴两种。所用铆钉是铝合金制品。铆钉是一根圆头钉,头部有防滑凸纹,头部上套上一个翻边的铝合金薄套管。铆钉有四种规格,为φ1.5×30、φ2×40、φ2.5×45及φ3×57。铆钉钳上有四个相应孔径的管嘴。一个放在钳头上,另外三个固定在钳胸部,随时可以替换(见图1)。 Here is a description of a kind of American-made rivet pliers, with straight mouth and curved mouth. The rivets used are aluminum alloy products. The rivet is a round head stud with a non-slip rib on the head and a thin-walled aluminium alloy sleeve on the head. Rivets come in four sizes: φ1.5×30, φ2×40, φ2.5×45, and φ3×57. The rivet pliers have four corresponding orifices. One is placed on the pliers and the other three are fixed on the pliers chest and can be replaced at any time (see Figure 1).
