Tensioners come in many sizes, such as 1" ratchet buckle , and of course 1.5 inches, 2 inches, etc.

There is a long groove on both sides of the grip of the tensioner for a blocking piece to be embedded, and the two long grooves are in a slidable form. An elastic piece is arranged between the blocking piece and the handle, and the elastic force of the elastic piece Pushes the baffle to engage with two ratchets. The two lugs of the body correspond to the position of the stopper when the handle is pivoted, and respectively have a concave part, a stopper, a sliding groove, and a groove in sequence, and the two pivoting parts of the handle correspond to the catch of the body. The plates each have a convex part, and the stopper is in a form of meshing with the ratchet when in the recessed part, and the height of the stop is higher than the ratchet teeth on the ratchet so that the stopper is in a form of disengaging from the ratchet when passing the stop.

The above is the structure of the tensioner, and the 2" ratchet buckle is also the above structural feature.
