Tool-free quick coupling

The creation of the "tool-free quick-engagement device" relates to a device that can realize the technical field of connecting or separating two objects without tools.

Many items in the workshop have a need to connect or separate depending on the state of use. In the case of a conventional wheelchair, most of them are not motivated, and manual operation is required to move forward and backward. For many users, there are inconveniences and restrictions in action. Therefore, some people have developed an electric vehicle head that can be attached to the front of a conventional wheelchair as a power source, so that the wheelchair can be driven by power. Most of the attached power head structure can only be used outdoors, and in order to save space when indoors, most of them will be detached to facilitate the wheelchair to move indoors. The connection structure between the traditional electric vehicle head and the wheelchair is poorly designed, and the tools are often used in use, and the structure is complicated and the operation is troublesome, which is inconvenient for the elderly or the disabled to use.
