C型卡E型卡（可定制）

There are two common methods for axial positioning using clips. The first involves a C-shaped snap ring that fits into a circular groove on a shaft. The second uses an E-clip that is inserted through a square hole in a shaft.

Absolutely no need to worry about strength issues; it merely prevents movement along its axis and isn't under significant force. You can refer to the actual object photos provided for the model.

卡扣主要用于轴向定位，可以在轴上凹环形卡槽，使用C型卡扣；也可以在轴上方形洞穿，使用E形卡槽。 

完全无须担心强度问题，它只是轴向防止移动，并没有强受力，可以看模型给的实物图片。
