The bowden cable has good flexibility and can effectively transfer tensile force, so that the driving end and the executing end of the exoskeleton system can be connected by using the rope driving mechanism of the bowden cable, and in general, the rope driving mechanism of the bowden cable is not convenient to install and is usually assembled for long-term use, and the bowden cable needs to be detached by a tool when the bowden cable has faults and needs maintenance and replacement; however, in the application of the wearable exoskeleton, the user needs to wear or take off the exoskeleton frequently, and as the driving end and the executing end cannot be disassembled or assembled efficiently and quickly, the user is more intuitionistic, so that the user is inconvenient to wear and take off the exoskeleton, the user experience is reduced, and the maintenance or replacement of the driving end or the executing end in the exoskeleton is also inconvenient; accordingly, wearable exoskeleton systems are also increasingly being iteratively improved toward modular designs in order to meet the current broader, more flexible user needs. For example, in the application No.: 202010956888.1 in the patent application file, the name of which is a quick-release device for a pull wire, a quick-release device for a bowden wire is designed, but in the patent application, the quick-release device has a complex structure, numerous nonstandard parts and difficult processing and manufacturing, so that the quick-release device is not beneficial to mass production and assembly; secondly, the force arm of the pressing part of the clamping tenon in the patent application is smaller, and larger force is required to drive the inner clamping tenon to finish the displacement required by disassembly through the outer clamping tenon, so that the flexible response and the convenience of use of the quick-release structure are not facilitated; in addition, the rope-driven exoskeleton is generally designed for simplicity and light weight, but the overall size of the quick-release device is large, so that the quick-release device is difficult to integrate into the overall structure of the exoskeleton system, and is not beneficial to practical application.

The bowden cable quick-release device is indispensable to the modularized design of the rope-driven exoskeleton system, and a bowden cable quick-release mechanism which is not yet put into use at present is needed to be designed, so that a quick-release device capable of transmitting large tensile force and being quickly and conveniently disassembled and assembled is needed to be designed, and the magnetic-type bowden cable quick-release device is provided.
