Abstract
Provided is a lock, including a locking module and a driving module. The locking module includes a latch mounted on a first main body, an oblique pin ring gear mounted on a second main body and adapted to the latch. A radial thickness of the oblique pin ring gear changes continuously. A first slot is arranged on the latch. The driving module is used for driving the oblique pin ring gear to move in a circular motion, such that on the latch in a closed position the oblique pin ring gear clips to or separates from the first slot. The lock mechanism can realize inward or outward arcuate connection and planar connecting without finishing.
