A fastening bracket is provided. The fastening bracket is adapted to be affixed to a mounting surface and connected to an object. The fastening bracket includes a base and a connection unit. The base is for being affixed to the mounting surface. The connection unit is connected to the base, wherein the connection unit includes a unit inclined surface and at least one unit abutting portion. The object includes at least one object abutting portion. When the object is in a separated state, the object abutting portion is separated from the unit abutting portion, and when the object is in a connected state, the object abutting portion abuts the unit abutting portion. While the object is being moved from the separated state to the connected state, the object abuts the unit inclined surface and slides relative to the unit inclined surface.

Provided is a lock, comprising a locking module and a driving module, wherein the locking module comprises a latch mounted on a first main body, a oblique pin ring gear mounted on a second main body and adapted to the latch; the radial thickness of the oblique pin ring gear changes continuously; a first slot is arranged on the latch, and wherein 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.
