扣位提供了一种不但方便快捷而且经济的产品装配方法，因为扣位的组合部份在生产成品的时候同时成型，装配时无须配合其他如螺丝、介子等紧锁配件，只要需组合的两边扣位互相配合扣上即可。
Buckling provides a convenient, fast and economical method of product assembly, because the combination part of the buckle is formed at the same time when the finished product is manufactured. There is no need to cooperate with other locking parts such as screw and meson in assembly, as long as the two side buckles of the combination need to cooperate and buckle each other.
扣位的设计虽可有多种几何形状，但其操作原理大致相同：当两件零件扣上时，其中一件零件的勾形伸出部份被相接零件的击缘部份阳雕刻 水刀切割机 pvc软管 手套生产设备 保定平面设计培训 保定室内设计培训 果树反光膜推开，直至击缘部份完结为止；及後，藉着塑胶的弹性，勾形伸出部份即时复位，其後面的凹槽亦即时被相接零件的击缘部份嵌入，此倒扣位置立时形成互相扣着的状态。
Although the design of buckling position can have many geometric shapes, its operation principle is basically the same: when two parts are buckled, the hook extension part of one part is pushed away by the strike edge part of the connected part until the strike edge part is finished; and then, with the elasticity of plastic, the hook extension part is immediately reset, and the concave behind it. The groove is also immediately embedded in the striking edge part of the connected parts, and the inverted position immediately forms a state of interlocking
