A plurality of notches 43 are provided at intervals along the circumferential direction of the connecting seat 4. Because the connecting seat 4 has a predetermined elasticity, under the action of an external force, the abutting portion 42 is contracted inward, so that the diameter thereof is smaller than that of the through hole 3, and enters the through hole 3. When the abutting portion 42 enters between the first to-be-connected component 1 and the second to-be-connected component 2, the external force is removed, and the abutting portion 42 is restored to the original state. Therefore, when the fastening device is in a locking state, the first abutting surface and the second abutting surface which are respectively positioned at two sides of the abutting portion 42 are respectively abutted against the first to-be-connected piece 1 and the second to-be-connected piece 2.

The connecting seat 4 is sleeved with an elastic element 6. The fastener 5 is arranged in the through hole 45 of the connecting base 4 in a penetrating way until the end 52 of the fastener 5 is propped against the connecting base 4, and the connecting rod 51 is connected with the second to-be-connected piece 2.
The fastening device has the advantages of simple structure, small volume and low requirement on installation space. Auxiliary tools are not needed in the installation process, and the installation is convenient and quick. Since the locking force of the fastening element 5 acting on the connecting socket 4 is transmitted to the connecting piece by the abutment 42 during the locking process. Therefore, the part between the first to-be-connected part 1 and the second to-be-connected part 2 can be protected, and the force acting on the first to-be-connected part 1 in the locking process is prevented from being transmitted to the part needing to be protected.
