Which are the two most common types of plastic buckles

1.D - ring (D Ring)

The D ring is named after its shape like the letter "D". It has a wide use. It is often used on a strap to fix the water pipe and maybe hang some small objects (do many donkeys often put a towel in the D ring to wipe the sweat on their faces when they are on the road?). There are not many varieties of D ring. The radian is very slippery and suitable for scratching with the index finger or thumb, so some bags will plan the D ring in the local area. For example, there is a D ring on the right front of the Travel bag's back belt, which is designed to help with the right hand when the package is too heavy. Sometimes the outer hanging system uses a D - shaped ring.

2. hook (Hook)

There are many kinds of hooks, there are very standard plastic hooks, and some strange shapes. Generally speaking, no matter what kind of accessories, the more eccentric the shape is, the less useful it is. Here are some typical examples. Plastic hooks are rarely used in the hanging system, because the things outside the tour process are very simple and bump, and the plastic things are simply damaged, no matter how strong the texture is. Generally, large hooks are often used on the backpack of a waist bag or leisure bag, and are used in conjunction with the D ring on both sides of the bag. Small hooks are often used in bags, hanging keys and so on. The hook of the left picture is strong enough to rotate and match the metal opening of the tension spring, and then avoids the defect that the plastic fastener is simply broken. Generally used for single shoulder bag strap and D ring link. Such strength hooks are sometimes used for hanging on the outside. Small shape hooks are usually used to hang small bags, keys and other small objects in the bag.
