Tensioners are not particularly common when we say that they are common, but they can be seen when they are uncommon. So next we talk about the structure of a 1" ratchet buckle .

A safety release structure of a ratchet buckle is pivotally connected to a body and a grip by a shaft threading assembly, a lug protruding on both sides of the body, and a pivoting part protruding on both sides of the grip. The shaft passes through the two lugs and the two pivotal portions to pivotally connect the body and the grip. The shaft is coupled with a ratchet wheel between the two lugs and the two pivotal portions, and each ratchet wheel is provided with multiple For the ratchet, both sides of the main body are respectively provided with a long groove for a detent piece to be embedded in the two long grooves in a slidable form, and spring is arranged between the detent piece and the main body. The detent piece is pushed by the elastic force of the spring to engage with the two ratchet wheels, and the two sides of the grip are respectively provided with a long groove for a blocking piece to be embedded in the two long grooves and present a slidable form.

The above is the structure of a 2" ratchet buckle .
