選購指南

彈簧鉗(扣環鉗)專門用於安裝與拆卸 C 型扣環(Circlip)及 E 型扣環(Retaining Ring),鉗頭插腳對準扣環孔位後即可撐開或縮合,讓扣環通過軸徑卡入溝槽或從溝槽退出。扣環安裝若以一字起子或尖嘴鉗強行操作,容易造成扣環形變或脫手彈出,彈簧鉗的設計確保力量均勻作用於扣環兩端孔位。長寬代理品牌的彈簧鉗適合機械設備維修、汽機車引擎拆解與精密零件組裝使用。

彈簧鉗怎麼選?

確認需要彈簧鉗後,依三個面向選型:

  • 開口方向(內/外扣環): 外扣環鉗(Circlip)夾持時鉗口向外撐,用於安裝在軸外徑的扣環;內扣環鉗(Internal)夾持時鉗口向內縮,用於安裝在孔內徑的扣環;確認扣環位置再選型
  • 扣環尺寸範圍: 鉗頭插腳間距和可操作的扣環直徑有關,選購前確認扣環的名義直徑(通常標示於零件圖),確保所選鉗具的適用範圍涵蓋
  • 角度與視線: 直頭款適合正面可視位置;彎頭款(45° 或 90°)適合引擎艙內部、深孔中或正面無法看清扣環的位置,操作時可調整角度讓插腳對準扣環孔
