Referring to fig. 1 and 2, the locking handle 4 is rotatably coupled to the fixing member 3, and specifically, both ends of the fixing member 3 are rotatably coupled to the locking handle 4. The end of the locking handle 4 connected with the fixing piece 3 is provided with a protruding part 41 in a forming mode, and the protruding part 41 can be triangular, quadrilateral, cam-shaped or other shapes capable of achieving locking. In the present embodiment, the boss 41 is in the shape of a cam, and the axis of the boss 41 in the shape of a cam is the axis of the mount 3. The other end of the locking handle 4 and the side wall of the locking handle 4 can be attached to the outer wall of the elastic buckle 1.

Further, referring to fig. 3 and 4, the quick release fastener further includes a release preventing member 5. Specifically, the threaded hole on the fixing piece 3 penetrates through the fixing piece 3, the connecting piece 2 can be screwed out of the threaded hole on the fixing piece 3, and the anti-falling piece 5 is detachably connected and fixed with one end of the connecting piece 2, which penetrates out of the threaded hole on the fixing piece 3. Removable connection fixtures include, but are not limited to, threaded connections, plugging, or clamping. In this embodiment, the anti-falling member 5 is connected with the connecting member 2 through threads, the anti-falling member 5 may be a screw, an external thread is formed on the anti-falling member 5, and an internal thread adapted to the external thread on the anti-falling member 5 is formed on the connecting member 2. When in use, the anti-falling piece 5 can be abutted on the fixing piece 3, so as to fix the fixing piece 3 in an abutting way.

Further, referring to fig. 2 and 4, in use, since the locking handle 4 is often required to be pulled, the protrusion 41 on the locking handle 4 is easy to wear the elastic buckle 1, and in order to reduce the wear of the protrusion 41 on the elastic buckle 1, the gasket 6 is disposed between the elastic buckle 1 and the protrusion 41 on the locking handle 4, and in use, the gasket 6 is sleeved on the connecting piece 2, and when the locking handle 4 is pulled, the protrusion 41 extrudes the gasket 6.
