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，卡扣机厂家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 musiban.89ix.comshilongw.89ix.comfangpaow.89ix.comgangbanw.89ix.comsangna.89ix.com

wenquan.89ix.comcombination part of the buckle is formed at the same time in the production of finished products. There is no need to cooperate with other locking parts such as screw and meson when assembling. Buckling machine manufacturers only need to cooperate with each other on both sides of the buckle.

卡扣机厂家对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。
The buckle machine manufacturer can design the buckle position with various geometric shapes, but its operation principle is basically the same: when two parts are buckled, the hook extension part of one part is pushed aside by the flange part of the connecting parts until the flange part is finished; and then, with the elasticity of plastic, the hook extension part is immediately reset, and the groove behind it is immediately hit by the connecting parts. The edge part is embedded, and the upside-down position immediately forms a state of interlocking.
