廉价的手动工具不具备绝缘外皮压接调整功能。手动工具是用来压接为数不多的端子。你无法在手动工具上调整绝缘外皮的压接，不过，在许多压接场合，刺穿绝缘外皮的绝缘外皮压接仍可被视为合格的压接。该标准仅适用于手动工具，因为其压接循环速度慢。若绝缘外皮压接刺穿了绝缘外皮，则芯线倾向于朝两边移动，但并未受损。
Cheap manual tools do not have the function of adjusting the pressure connection of insulating outer skin. Manual tools are used to press a few terminals. You can't adjust the pressure connection of the insulating skin by manual tools, but in many cases, the pressure connection of the insulating skin piercing through the insulating skin can still be considered qualified. This standard is only applicable to manual tools because of their slow crimping cycle. If the insulating outer skin is pierced by pressing, the core tends to move toward both sides, but it is not damaged.
