The Aluminum Clip is distinguished by function. The design of the clips can
be divided into two types: permanent type and detachable type. The design of the
permanent clip is easy to install but not easy to remove. The design of the
detachable clip is easy to install and remove. The principle is that the
hook-shaped extension of the detachable clip is provided with an appropriate
lead-in angle and a lead-out angle to facilitate the buckle-up and separation.
The lead-in and lead-out angles directly affect the force required for the clip
and the separation. The permanent type of clip has only the introduction angle
and no design of the lead angle.
