The embodiment of the invention discloses an annular wall locking mechanism which comprises N annular walls sequentially arranged in a sleeving mode in the radial direction and self-tapping pieces arranged on the annular walls, each self-tapping piece comprises a self-tapping thread part and a rod part connected with the self-tapping thread part, the rod parts are arranged on the annular wall located on the innermost side in a penetrating mode, and the N is larger than or equal to 1. The self-tapping thread part is in threaded connection with the other N-1 ring walls, the rod part is a cylinder with a smooth surface, and N is a positive integer larger than or equal to 3. And the maximum diameter of the rod part is smaller than the thread small diameter of the self-tapping thread part. By adopting the structure, the embodiment of the invention has the following advantages: the embodiment of the invention can eliminate the tolerance generated by manufacturing and assembling the multi-layer ring wall. The embodiment of the invention has anti-vibration and anti-loosening effects and can be applied to vibration environments such as automobiles. The embodiment of the invention can be flexibly applied to various materials or composite materials by customizing the PEM tooth grains. According to the embodiment, the locking position can be flexibly arranged, and installation is convenient.
