1. A fastening apparatus, comprising:
a base having a first sliding groove;
a rotation member pivotally connected to the base and having a second sliding groove, wherein the rotation member has at least two locking states, wherein the at least two locking states are adjacent and spaced apart by a predetermined angle;
a locking member having a locked state and an unlocked state, wherein in the locked state, the rotation member is in one of the at least two locking states, and the locking member is located in both the first sliding groove and the second sliding groove to limit rotation of the rotation member relative to the base; in the unlocked state, the locking member is withdrawn from the first sliding groove or the second sliding groove to allow the rotation member to rotate relative to the base, so as to switch the locking states of the rotation member;
an elastic element operably connected to the locking member and configured to maintain the locking member in the locked state; and
a releasing member operably connected to the locking member and configured to drive the locking member to move against an elastic force of the elastic element, such that the locking member is switched from the locked state to the unlocked state;
wherein the locking member comprises a central portion and at least one protruding portion that protrudes from the central portion in a radial direction, the first sliding groove comprises a first central groove portion and at least one first extending groove in communication with the first central groove portion, the second sliding groove comprises a second central groove portion and at least one second extending groove in communication with the second central groove portion, the at least one first extending groove is at least two first extending grooves, and/or the at least one second extending groove is at least two second extending grooves, the central portion is slidably fitted with the first central groove portion and the second central groove portion, and the at least one protruding portion is slidably fitted with the at least one first extending groove and the at least one second extending groove.
