[0015] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0016] like Figure 1-Figure 2 As shown, a replaceable buckle fixing device of the present invention comprises: A housing 1, wherein the interior of the housing 1 is hollow to form a receiving cavity; The pull rope assembly is assembled in the housing 1 and is blocked by a buckle body 2 at one end of the housing 1 .

[0017] Among them, a buckle movable position 10 is set at one end of the shell 1, and the buckle body 2 is inserted and set in the buckle movable position 10; A first buckle area 7 and a second buckle area 8 are disposed at one end of the buckle active position 10 , and the first buckle area and the second buckle area 8 correspond to the buckle body 2 .

[0018] The pull rope assembly includes a pull rope body 4, a pull rope seal 5 and a return spring 6; A support block 11 is provided at one end of the pull rope body 4, and the return spring 6 is sleeved on the pull rope body 4 and contacts the support block 11; the pull rope seal 5 is also sleeved on the stretching body, and the other end of the return spring 6 contacts the other end of the pull rope seal 5.

[0019] Among them, the support block 11 end of the pull rope body 4 is placed in the shell 1, and the pull rope seal 5 is placed in the through hole of the shell 1, which not only ensures the flexible extension and contraction of the pull rope when subjected to force, but also can quickly return to the initial state when there is no external force.
