Among them, the main body 21 has a locked state and an initial state relative to the first body 1, and when the main body 21 is in the locked state, it is used to fix the first to-be-fixed part 4.

[0031] In this embodiment, the fastening device is usually applied to the mainboard 3, the first body 1 is fixedly arranged on the mainboard 3, the first to-be-fixed part 4 and the second to-be-fixed part 5 can be electronic components including but not limited to SSD, PCB or WiFi board, and the first to-be-fixed part 4 and the second to-be-fixed part 5 are usually different in size. Since the fastening device includes the first body 1 and the second body 2, the main body 21 of the second body 2 can rotate around an axis relative to the first body 1, so when the main body 21 rotates to lock with the first body 1, the first to-be-fixed part 4 can be fixed; the main body 21 of the second body 2 is connected with a pressing part 22, and when the pressing part 22 and the main body 21 are buckled, the second to-be-fixed part 5 can be fixed. Two sockets are arranged on the mainboard 3, and the first socket is defined as the one arranged close to the first body 1 and the second socket is defined as the one arranged far from the first body 1. The first socket is arranged 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.

[0032] In this embodiment, taking the first to-be-fixed component 4 as a WiFi board and the second to-be-fixed component 5 as an example, the first to-be-fixed component 4 and the second to-be-fixed component 5 can be inserted into different sockets. Assuming that the length of the first to-be-fixed component 4 is shorter than that of the second to-be-fixed component 5, one end of the first to-be-fixed component 4 is inserted into the first socket, and one end of the second to-be-fixed component 5 is inserted into the second socket. In the actual operation process of fixing the first to-be-fixed component 4 and the second to-be-fixed component 5, first, the main body 21 is opened from the first body 1, so that the main body 21 is in an initial state. state, then snap the end of the first part to be fixed 4 away from the first socket onto the first book, rotate the main body 21 to snap the main body 21 with the first body 1, so that the main body 21 is in a locked state, and the first part to be fixed 4 is fixed; when the first part to be fixed 4 is fixed, open the pressing part 22 from the main body 21, so that the pressing part 22 is in an open state, and then snap the end of the second part to be fixed 5 away from the second socket onto the main body 21, and then snap the pressing part 22 with the main body 21, so that the pressing part 22 is in a snapped state, and the second part to be fixed 5 is fixed. In this way, the fixing of parts to be fixed of different specifications can be completed by the fastening device, which has a simple structure, convenient operation, improved production efficiency, and low cost.

[0033] Reference Figure 2 As shown, in one embodiment, the first body 1 includes a base 11 and two oppositely disposed side walls 12 , and the base 11 and the two side walls 12 are combined to form a receiving groove 112 for receiving the main body 21 .

[0034] Specifically, in one embodiment, two side shafts 211 are disposed on the main body 21 , and the two side shafts 211 are disposed opposite to each other. The main body 21 is rotatably connected to the two side walls 12 via the two side shafts 211 .

[0035] In this embodiment, the side shaft 211 is provided on the main body 21 so that it can rotate around the axis relative to the first body 1. The rotation angle of the main body 21 relative to the first body 1 when it is in a locked state is defined as 0°. When the main body 21 rotates in a direction away from the first body 1, and usually when the rotation angle is greater than 70°, the first to-be-fixed member 4 is pressed in a direction close to the main board 3 until it is engaged with the first body 1, and will not interfere with the main body 21.

[0036] In one embodiment, the side wall 12 of the first body 1 is provided with a locking hole 121, and the two locking holes 121 are arranged opposite to each other. The main body 21 of the second body 2 includes two buckles 212. When the main body 21 is in a locked state, the two buckles 212 are engaged with the two locking holes 121 one by one.

[0037] In this embodiment, the first body 1 and the second body 2 are both made of rubber material, which has a certain elasticity, can be elastically deformed and has the ability to rebound. Therefore, when the main body 21 rotates from the initial state to the locked state, the buckle 212 first contacts the side wall 12 of the first body 1 and is squeezed and deformed by the side wall 12. During this process, the main body 21 continues to rotate in the direction close to the base 11 of the first body 1, and the buckle 212 presses against the side wall 12 to slide until the buckle 212 slides to the clamping hole 121 on the side wall 12, and the buckle 212 rebounds. At this time, the buckle 212 is clamped into the clamping hole 121 to complete the fixation, and at the same time, the main body 21 is limited in the Z direction in the three-dimensional coordinate system. When the main body 21 changes from the locked state to the initial state, the buckle 212 is elastically deformed by pressing the buckle 212, so that the buckle 212 is disengaged from the buckle hole 121. At this time, the main body 21 is rotated away from the base 11, and the buckle 212 presses against the side wall 12 to slide until the buckle 212 slides to separate from the side wall 12 and the buckle rebounds.

[0038] In one possible implementation manner, the base 11 has a first limiting portion 111 . The first limiting portion 111 defines a first through hole 1110 . The first limiting portion 111 is in a stepped shape.

[0039] Further, in an embodiment, a second limiting portion 213 is provided on a side of the main body 21 away from the first body 1 . The second limiting portion 213 is provided with a second through hole 2130 . The second limiting portion 213 is in a stepped shape.

[0040] In this embodiment, the first limiting portion 111 is used to engage with the first part to be fixed 4, the second limiting portion 213 is used to engage with the second part to be fixed 5, the second through hole 2130 passes through the main body 21, and the first through hole 1110 can be connected with the second through hole 2130, so that when the pressing portion 22 is in the snap-fit ​​state, it can be more tightly connected with the main body 21 and the first body 1.

[0041] Reference Figure 3 As shown, in one embodiment, the pressing portion 22 has a clamping member 24. When the pressing portion 22 is in a snap-fit ​​state and the main body 21 is in a locked state, the first through hole 1110 and the second through hole 2130 meet the coaxial condition, and the clamping member 24 is placed in the first through hole 1110 and the second through hole 2130.

[0042] In this embodiment, the length of the clamping member 24 can be designed according to actual needs, for example, the length of the clamping member 24 can be less than or equal to the depth of the second through hole 2130, or can be greater than the depth of the second through hole 2130. It is understandable that if the length of the clamping member 24 is greater than the depth of the second through hole 2130, when the pressing part 22 is in a buckled state and the main body 21 is in a locked state, the clamping member 24 can extend into the first through hole 1110, and at this time, the connection between the pressing part 22 and the main body 21 and the first body 1 can be more tightly connected, preventing the clamping member 24 from coming out of the second through hole 2130. The pressing part 22 is connected to the main body 21 by a connecting belt 23, and the connecting belt 23 can enable the pressing part 22 to move freely in space. The pressing part 22, the connecting belt 23 and the main body 21 are an integrally formed structure, or the three are connected by gluing or other methods.

[0043] In one embodiment, the buckle 212 is connected to the main body 21 via an elastic arm 214 , and the elastic arm 214 extends from the main body 21 .

[0044] In this embodiment, the buckle 212 is connected to the main body 21 through the elastic arm 214, which can make the process of the buckle 212 engaging with the locking hole 121 and the process of the buckle 212 being removed from the locking hole 121 more convenient and easy to operate. When the buckle 212 is pressed, the elastic arm 214 elastically deforms in the direction along the inside of the main body 21. If the external force applied to the buckle 212 is removed, the elastic arm 214 can rebound to the initial state. In this embodiment, the main body 21 can be made of materials including but not limited to metal, silicone, etc., as long as the above-mentioned effects can be achieved.

[0045] In one embodiment, a positioning portion 13 is disposed on a side of the base 11 away from the main body 21 , and the positioning portion 13 is protruded relative to the main body 21 .

[0046] In this embodiment, the positioning portion 13 is used to fix the first body 1 on the main board 3. Accordingly, a positioning hole is provided on the main board 3. The positioning portion 13 can engage with the positioning hole to prevent the first body 1 from rotating. The positioning portion 13 includes a first portion 131 and a second portion 132 that are arranged opposite to each other. The first portion 131 and the second portion 132 can be elastically deformed when subjected to an external force. In the process of setting the first body 1 on the main board 3, the first portion 131 and the second portion 132 are first squeezed simultaneously by an external force so that they can enter the positioning hole. When the first portion 131 and the second portion 132 are fully inserted into the positioning hole, the first portion 131 and the second portion 132 rebound and engage with the positioning hole to limit the position.

[0047] Reference Figure 5As shown, the present disclosure also provides a fastening structure, including a main board 3, a first part to be fixed 4 and a second part to be fixed 5, the main board 3 includes a first plug-in portion 31 and a second plug-in portion 32, the fastening structure also includes a fastening device as in any one of the above-mentioned embodiments, the first part to be fixed 4 is plugged into the first plug-in portion 31 and is fixed to the main board 3 by the fastening device, the second part to be fixed 5 is plugged into the second plug-in portion 32 and is fixed to the main board 3 by the fastening device.

[0048] In this embodiment, the first to-be-fixed part 4 and the second to-be-fixed part 5 can be electronic components including but not limited to SSD, PCB or WiFi board, and usually the first to-be-fixed part 4 and the second to-be-fixed part 5 have different sizes. Taking the first to-be-fixed part 4 as a WiFi board and the second to-be-fixed part 5 as an example, assuming that the length of the first to-be-fixed part 4 is shorter than the length of the second to-be-fixed part 5, one end of the first to-be-fixed part 4 is inserted into the first plug-in portion 31, and one end of the second to-be-fixed part 5 is inserted into the second plug-in portion 32. In the actual operation process of fixing the first to-be-fixed part 4 and the second to-be-fixed part 5, first open the main body 21 from the first body 1 to put the main body 21 in the initial state, and then move the first to-be-fixed part 4 away from the first body 1. One end of the first socket is engaged with the first book, and the main body 21 is rotated to engage the main body 21 with the first body 1, so that the main body 21 is in a locked state, and the first part to be fixed 4 is fixed; when the first part to be fixed 4 is fixed, the pressing part 22 is opened from the main body 21, so that the pressing part 22 is in an open state, and then the end of the second part to be fixed 5 away from the second socket is engaged with the main body 21, and then the pressing part 22 is engaged with the main body 21, and the pressing part 22 is in a locking state, and the second part to be fixed 5 is fixed. In this way, the fastening structure can complete the fixing of parts to be fixed of different specifications, with a simple structure, convenient operation, improved production efficiency, and low cost.
