防爆尖(jian)嘴(zui)鉗，別名修口鉗、尖(jian)頭鉗、尖(jian)咀(ju)鉗。它是(shi)由尖(jian)頭、刀口和鉗柄組成(cheng)，電工(gong)用尖(jian)嘴(zui)鉗的(de)鉗柄上套有額(e)定電壓500V的(de)絕緣套管(guan)。是(shi)一種常(chang)用的(de)鉗形(xing)工(gong)具。

防爆尖(jian)嘴(zui)(zui)鉗(qian)(qian)與(yu)普通尖(jian)嘴(zui)(zui)鉗(qian)(qian)不(bu)同。這是(shi)一(yi)個在(zai)特殊工(gong)(gong)作(zuo)場(chang)所(suo)(suo)使(shi)用(yong)(yong)(yong)的(de)(de)(de)手動工(gong)(gong)具。其材(cai)料(liao)的(de)(de)(de)特殊性起著關鍵作(zuo)用(yong)(yong)(yong)，可(ke)用(yong)(yong)(yong)于對特殊行(xing)業的(de)(de)(de)員工(gong)(gong)進行(xing)特殊的(de)(de)(de)維(wei)護工(gong)(gong)作(zuo)。當在(zai)易(yi)(yi)燃易(yi)(yi)爆等特殊工(gong)(gong)作(zuo)場(chang)所(suo)(suo)使(shi)用(yong)(yong)(yong)防爆尖(jian)嘴(zui)(zui)鉗(qian)(qian)時，由于夾線、拉出(chu)鐵(tie)器、敲擊其他(ta)物體，不(bu)會造成(cheng)機械(xie)火花(hua)引起的(de)(de)(de)事故，因此，防爆尖(jian)嘴(zui)(zui)鉗(qian)(qian)是(shi)一(yi)種鉗(qian)(qian)工(gong)(gong)器具產品。

工具材質：

防爆尖(jian)嘴(zui)(zui)鉗(qian)由(you)銅(tong)(tong)(tong)和其(qi)他稀有金屬進(jin)行合(he)金鑄造成形，然后(hou)經過一系列加工(gong)(gong)處理(li)成為成品(pin)，這種產品(pin)由(you)于(yu)材(cai)質(zhi)的特殊性，使產品(pin)具備了防爆的功能。防爆尖(jian)嘴(zui)(zui)鉗(qian)一般(ban)由(you)鋁銅(tong)(tong)(tong)合(he)金(鋁青(qing)銅(tong)(tong)(tong))和銅(tong)(tong)(tong)銅(tong)(tong)(tong)合(he)金(銅(tong)(tong)(tong)銅(tong)(tong)(tong))兩種材(cai)質(zhi)組成，其(qi)中鋁青(qing)銅(tong)(tong)(tong)的工(gong)(gong)作面硬度HRC在25°以上，拉(la)伸強度δb。

防爆(bao)(bao)尖(jian)(jian)頭鉗(qian)的特(te)殊(shu)材料取決于其使用(yong)范圍的限制.對要求不太嚴(yan)(yan)格的工(gong)(gong)作(zuo)場所，不得在要求不嚴(yan)(yan)格的工(gong)(gong)作(zuo)場所使用(yong)，石(shi)油、石(shi)化、化工(gong)(gong)、電(dian)子、礦山(shan)、加油站(zhan)、煤氣中轉站(zhan)等特(te)殊(shu)作(zuo)業場所不得使用(yong)此類(lei)工(gong)(gong)具和產品。在這些特(te)殊(shu)作(zuo)業場所使用(yong)防爆(bao)(bao)尖(jian)(jian)頭鉗(qian)不會(hui)有任何隱(yin)患。
