A handle sleeve is installed on one side of the handle assembly, and a handle is rotatably connected to one side of the inside of the handle assembly. Anti-detachment structures are installed on one side of both the fixed binding assembly and the movable binding assembly.

[0007] When in use, the long webbing connected to the movable binding component is connected at one end to a semi-circular shaft. By turning the butterfly wrench, the semi-circular shaft can be wound up to tighten the long webbing, thereby gradually tightening the fixed binding component and the movable binding component, and finally achieving a fastening effect.

[0008] Preferably, a semi-circular shaft is installed on the other side of the housing. Both ends of the outer wall of the semi-circular shaft are equipped with ratchet wheels. A butterfly wrench is installed at one end of the semi-circular shaft, and a bushing is installed at the other end. A shaped slot is opened on one side of the handle assembly. A movable pawl is installed above the shaped slot, and a return torsion spring is installed below the shaped slot. A pawl sleeve is installed on one side of the movable pawl. The long webbing connected to the movable binding assembly is wound up by the semi-circular shaft, thereby gradually tightening and stretching the fixed binding assembly and the movable binding assembly.

[0009] Preferably, the semi-circular shaft is rotatable with the housing, and the semi-circular shaft is rotatable with the internal hole of the handle assembly, so that the semi-circular shaft can rotate and wind up the long webbing.

[0010] Preferably, the irregularly shaped slot and the two ends of the movable pawl are inlaid, and the ratchet is symmetrically distributed about the vertical center line of the semi-circular axis, so that the movable pawl can resist the ratchet and prevent the semi-circular axis from reversing.

[0011] Preferably, the long webbing is installed on the outer wall of the bolt shaft and the semi-circular shaft respectively, so that the fastening distance of the long webbing can be adjusted when the semi-circular shaft rotates.

[0012] Preferably, the anti-detachment structure includes a female buckle, a retaining sleeve, and a male buckle. The female buckle is installed at one end of the fixed binding component and the movable binding component.

The female buckle and the retaining sleeve prevent the fixed binding component and the movable binding component from slipping off after installation.

[0013] Preferably, the female buckle and the male buckle have an interlocking structure, and the card sleeve and the movable binding component have an embedded structure, thereby making the installation of the card sleeve more convenient.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by repeatedly pulling the handle assembly, the semi-circular shaft is rotated to wind up the long webbing connected to the movable binding assembly, thereby adjusting the length of the device; at the same time, the simple female and male buckle locking structure makes the hooks of the fixed binding assembly and the movable binding assembly more secure and convenient.

[0015] 1. When using the fastening device, repeatedly rotate and turn the handle assembly to make the movable pawl drive the semi-circular shaft and ratchet to rotate, so that the long webbing gradually wraps around the outside of the semi-circular shaft, thereby gradually shrinking and tightening the length of the fastening device. When the handle assembly is opened to a certain angle, the flange on the handle pushes open the elastically reset stop pawl so that it is disengaged from the ratchet, so that the long webbing can be pulled out along the outside of the semi-circular shaft.
