[0030] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0031] Reference Figure 1 and Figure 3 As shown, a fastening device of an exemplary embodiment of the present invention includes a first body 1 and a second body 2, the second body 2 includes a main body 21 and a pressing portion 22, a latch portion 212 is formed between the pressing portion 22 and the main body 21, and is used to fix the second part to be fixed 4, the second body 2 is rotatably connected to the first body 1, so that the second body 2 can rotate relative to the first body 1 along the axis of the main body 21, and a limiting portion 211 is formed between the main body 21 and the first body 1, and is used to fix the first part to be fixed 3.

[0032] In this embodiment, the fastening device is usually applied to the mainboard 5, the first body 1 is fixedly arranged on the mainboard 5 by welding, fastening, etc., the first to-be-fixed part 3 and the second to-be-fixed part 4 may include but are not limited to electronic components such as SSD, PCB or WLAN card, and the sizes of the first to-be-fixed part 3 and the second to-be-fixed part 4 are usually different. Since the fastening device includes the first body 1 and the second body 2, the second body 2 is connected to the first body 1, and a limiting portion 211 is formed between the main body 21 of the second body 2 and the first body 1, the limiting portion 211 can fix the first to-be-fixed part 3; a latching portion 212 is formed between the pressing portion 22 of the second body 2 and the main body 21, and the second body 2 can rotate relative to the first body 1 along the axis of the main body 21, and when the second body 2 rotates until the pressing portion 22 abuts against the surface of the second to-be-fixed part 4, the latching portion 212 can latch the second to-be-fixed part 4. There are two sockets on the main board 5. The one close to the first body 1 is defined as the first socket, and the one far away from the first body 1 is defined as the second socket. The first socket is defined between the second socket and the first body 1, and the second socket, the first socket and the first body 1 are located on the same straight line.

[0033] Reference Figure 5 to Figure 7As shown, in this embodiment, taking the first part to be fixed 3 as a WLAN card and the second part to be fixed 4 as an SSD as an example, the first part to be fixed 3 and the second part to be fixed 4 can be inserted into different sockets. Assuming that the length of the first part to be fixed 3 is shorter than that of the second part to be fixed 4, one end of the first part to be fixed 3 is inserted into the first socket, and one end of the second part to be fixed 4 is inserted into the second socket. In the actual operation of fixing the first part to be fixed 3 and the second part to be fixed 4, first fix the first body 1 on the main board 5, then snap one end of the first part to be fixed 3 away from the first socket onto the first body 1, and then install the second body 2, thereby fixing the first part to be fixed 3 in the limiting portion 211, and fixing the first part to be fixed 3; rotate the latching portion 212 of the second body 2 to the side away from the second part to be fixed 4, then snap one end of the second part to be fixed 4 away from the second socket onto the main body 21, and then rotate the second body 2 so that the latching portion 212 snaps with the second part to be fixed 4, and the second part to be fixed 4 is fixed. Thus, the fastening device can be used to fix parts of different specifications up and down, and no tools are needed, the structure is simple, the operation is convenient, the assembly efficiency is improved, and the cost is low. It can be understood that the fastening device can also only fix one of the first to-be-fixed part 3 and the second to-be-fixed part 4.
