[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] For reference Figure 1-4 The utility model is described as follows:

[0027] Embodiment 1: An adjustable buckle comprises a base 1, a locking tongue 4, a handle 2, and a hook ring 3.

[0028] The base 1 is in the shape of an elongated strip and a plate-like structure. Lugs 12 are respectively provided on both sides of the width direction of the base 1. The lugs 12 are arranged perpendicularly to the base 1. The lugs 12 are arranged at one end of the length direction of the base 1. A fixing hole is provided on the base 1. The base 1 is fixedly connected to the fixing surface by screws, and the screws are connected in the fixing hole.

[0029] The handle 2 is a U-shaped structure, and the two ends of the handle 2 are respectively hinged to two lugs 12, and the lugs 12 are provided with hinge holes. The two ends of the handle 2 are respectively provided with corresponding through holes, and the through holes and the intersection holes are connected with an intersection axis.

[0030] The hook ring 3 includes an elongated rod body 31, one end of the rod body 31 is bent to form an annular hook ring 32, the hook ring 32 is locked with the lock tongue 4, the other end of the rod body 31 is connected to the handle 2 through a connecting plate 6, the connecting plate 6 is connected to the inner side of the handle 2, the connecting plate 6 is rotatably connected to the handle 2, both sides of the connecting plate 6 are provided with a rotating shaft, the two side walls of the handle 2 are provided with a through hole connected to the rotating shaft, the connecting plate 6 is provided with a through hole connected to the rod body 31, the other end of the rod body 31 is threadedly connected with a nut 8, and the connecting plate 6 is located between the nut 8 and the hook ring 32. In the above technical solution, the hook ring 3 is rotatably connected to the handle 2 through the connecting plate 6, and the distance from the hook ring 32 to the lock tongue 4 can be adjusted by adjusting the position of the nut 8 on the rod body 31.

[0031] The locking tongue 4 includes a plate body portion 41, one side of the plate body portion 41 is bent and extended to form a hook 42, the hook ring 32 is locked and connected to the hook 42, a fixing hole is provided on the plate body portion 41, the plate body portion 41 is fixedly connected to the fixing surface by screws, and the screws are connected in the fixing hole.
