The adjustment buckle of the luggage buckle, as the name suggests, is a buckle that adjusts the length of the webbing. There are many kinds of adjustment buckles for the luggage buckle.

The Japanese buckle, also known as the third-speed buckle, is used to adjust the length of the webbing. It is also the most common type of adjustment buckle we use in luggage. Because it is relatively simple and has a poor anti-slip effect, it is generally used in casual bags, school bags, satchels and other loads. in a lighter bag. Because of the need, sometimes there are some Japanese buckles with ears on both sides.
The mesh buckle, also known as the ladder buckle and the fourth-speed buckle, although some Japanese buckles are in the middle of the adjustment rod to increase the friction and enhance the anti-skid effect, the anti-skid effect is also limited. The mesh buckle has an adjustment rod in the middle of the Japanese buckle, which can play a good anti-slip effect, so it is generally used in bags with heavy loads, such as travel backpacks, mountaineering bags, etc.
The adjustment buckle in the bag buckle is not only used to adjust the length of the strap, but also adjust the size of the backpack according to the number of items in the backpack, which can fix the items and reduce the space.
From this point of view, the role of the adjustment button in the luggage cannot be ignored.
