The motion switching linkage mechanism realizes the switching from the first motion mode, the deformation mode and the second motion mode through the linkage among the parts of the motion switching linkage mechanism, does not need additional electric control, and has low cost, long service life and less energy loss.

What has been described above is merely the principles and preferred embodiments of the present invention. It should be noted that, for those skilled in the art, on the basis of the principle of the present invention, several other modifications can be made, and the protection scope of the present invention should be considered.
