[0002] A hard disk is an essential component in a server, and a hard disk bracket is used to fix the hard disk, and is basically used in every server.

[0003] In the related art, in order to fix the hard disk to the bracket, a screw is usually fixed between the hard disk and the bracket by a manual or electric screwdriver, or the screw is disassembled from the hard disk and the bracket. Since the worker needs to fix the bracket and the hard disk and then tighten or loosen each screw one by one during the fixing or disassembling process, it is time-consuming and laborious, thereby resulting in low work efficiency. CONTENT OF THE UTILITY MODEL

[0004] In view of the above problems, the present application provides a fastening device, which can solve the problem of low installation and disassembly efficiency of the hard disk when being assembled to the hard disk bracket.

[0005] To solve the above technical problems, the present application provides a fastening device, comprising:

[0006] a support configured to place and fix the bracket and the hard disk, wherein the bracket is used to fix the hard disk through a fastener;

[0007] a rotating member provided on the support and used to rotate the fastener, wherein the rotating member can drive the fastener to rotate to fasten or loosen the bracket and the hard disk when the bracket and the hard disk are placed on the support.

[0008] In the technical scheme of the present application, the hard disk is only needed to be placed on the bracket, and then the bracket is placed on the support together with the hard disk. At this time, under the fixation of the support, the corresponding fastener is driven to rotate by the rotating member, so that the bracket and the hard disk can be fastened together or loosened. The whole process has high automation degree, and effectively improves the work efficiency. At the same time, since the worker does not need to contact the bracket during the fastening or loosening process, the bracket is avoided from scratching the worker.

[0009] In some embodiments, the support comprises a support frame and at least two side frames.

[0010] The support frame is used to place and fix the bracket and the hard disk, the two side frames are correspondingly arranged on the two sides of the support frame along a first direction, the rotating member is arranged on the opposite sides of the two side frames, and the side frames can move along the first direction relative to the support frame, wherein the first direction is the direction in which the two side frames approach or move away from each other.

[0011] In this way, when the side frame moves relative to the support in the first direction, the rotating member can be driven to move close to or away from the support, so as to facilitate the movement of the rotating member to the predetermined position.

[0012] In some embodiments, the fastening device further comprises a driving member for driving the side frame to move in the first direction.

[0013] In this way, the driving member can drive the side frame to move in the first direction, thereby facilitating the adjustment of the position of the side frame.

[0014] In some embodiments, the fastening device further comprises a telescopic rod arranged between the support and the side frame in the first direction.

[0015] The driving member is connected with the telescopic rod for driving the telescopic rod to extend or shorten in the first direction.

[0016] Since the telescopic rod is arranged between the support and the side frame in the first direction, the side frame can only move relative to the support in the first direction under the limitation of the telescopic rod.

[0017] In some embodiments, the fastening device further comprises a first detection member electrically connected with the driving member for detecting the position of the telescopic rod.

[0018] By arranging the first detection member, the position of the telescopic rod can be conveniently detected. When the telescopic rod extends or shortens to the predetermined position, the first detection member sends a detected signal to the controller, and the controller controls the driving member to stop working.

[0019] In some embodiments, the support comprises a first connecting plate, a second connecting plate and a third connecting plate, and the first connecting plate, the second connecting plate and the third connecting plate form a triangular prism structure.

[0020] The outer side of the first connecting plate is used for placing and fixing the bracket and the hard disk, and the two side frames are arranged on the two sides of the triangular prism in the axial direction of the triangular prism.

[0021] Since the triangular prism structure itself has good stability, when the bracket and the hard disk are placed on the first connecting plate, the bracket and the hard disk are relatively stable.

[0022] In some embodiments, the first connecting plate is provided with a baffle on the side facing the second connecting plate, and the bracket abuts against the baffle when the bracket and the hard disk are placed on the first connecting plate.

[0023] In this way, when the bracket and the hard disk are placed on the first connecting plate, the bracket can be prevented from sliding off the first connecting plate under the blocking of the baffle.

[0024] In some embodiments, the fastening device further comprises at least two guide rods, the two guide rods are arranged on both sides of the first connecting plate along the axial direction of the triangular prism.

[0025] When the bracket is placed on the first connecting plate, the two sides of the bracket can be prevented from deviating during placement under the limitation of the two guide rods.

[0026] In some embodiments, the fastening device further comprises at least two wing plates, the two wing plates are arranged on both sides of the first connecting plate along the axial direction of the triangular prism, the wing plates extend outward relative to the first connecting plate, and the wing plates are located above the guide rods in a second direction, wherein the second direction is the direction in which the bracket is inserted into the first connecting plate.

[0027] Since the two sides of the bracket can swing by themselves, when the bracket is placed on the first connecting plate, the two sides of the bracket can be quickly inserted into the first connecting plate under the limitation of the corresponding wing plates, direct manual contact with the bracket is reduced, and safety is enhanced.

[0028] In some embodiments, the fastening device further comprises a fixing net, the fixing net is connected with the first connecting plate and the baffle, and the fixing net, the first connecting plate and the baffle enclose an inner cavity for fixing the bracket.

[0029] Since the fixing net, the first connecting plate and the baffle can enclose an inner cavity for fixing the bracket, when the bracket is placed on the first connecting plate together with the hard disk, the bottom of the bracket and the hard disk is located in the inner cavity, and the bracket and the hard disk are prevented from falling off the first connecting plate.

[0030] The above description is only a summary of the technical solutions of the present application. In order to enable the technical means of the present application to be more clearly understood, and to be implemented according to the content of the description, and in order to enable the above and other purposes, characteristics and advantages of the present application to be more apparent and easy to understand, the following specific embodiments of the present application are described.

[0054] The hard disk is an essential component in the server, and the hard disk bracket is used to fix the hard disk, which is basically used in each server.

[0055] In order to solve the problem of low installation and disassembly efficiency of the hard disk when assembled to the hard disk bracket, an embodiment of the present application provides a fastening device, as shown in Figure 1 and as shown in Figure 2 , Figure 3 The fastening device comprises a support 10 and a rotating part 13, wherein the support 10 is configured to place and fix a bracket 20 and a hard disk 21, and the bracket 20 is used to fix the hard disk 21 through a fastener 22; the rotating part 13 is arranged on the support 10 and is used to drive the fastener 22 to rotate; in the case that the bracket 20 and the hard disk 21 are placed on the support 10, the rotating part 13 can drive the fastener 22 to rotate, so that the bracket 20 and the hard disk 21 are fastened or loosened.

[0056] The support 10 in the embodiment can be a cube, a prism or other irregular structure, which can be determined according to actual conditions, and the embodiments of the present application do not limit this.

[0057] In the embodiment, the rotating part 13 can be an electric screwdriver, an electric screwdriver machine or the like, which can be determined according to actual conditions, and the embodiments of the present application do not limit this.

[0058] The fastener 22 in the embodiment is a screw, a bolt or the like.

[0059] The rotating member 13 in the embodiment can be fixed to the support 10 through a sliding rail, or the rotating member 13 can be fixed to the support 10 through an electric telescopic rod. The actual situation can be determined, and the embodiment of the specification is not limited in this regard.

[0060] In the embodiment, the number of the rotating members 13 is equivalent to the number of the screws that need to be fixed between the bracket 20 and the hard disk 21. For example, when there are four or six screws that need to be fixed between the bracket 20 and the hard disk 21, the number of the rotating members 13 is four or six. It can be understood that the number of the rotating members 13 can be increased or decreased according to the actual situation. For example, the number of the rotating members 13 can be greater than the number of the screws that need to be fixed. In this way, when one of the rotating members 13 fails, the redundant rotating member 13 can be used to replace the failed rotating member 13, thereby ensuring the normal operation of the overall device.

[0061] In use, after the bracket 20 and the hard disk 21 are placed on the support 11, the corresponding fastener 22, for example, a screw, is fixed to the rotating member 13 through magnetic force. When the screw on the rotating member 13 is aligned with the threaded hole on the bracket 20 and the threaded hole on the hard disk 21, the rotating member 13 is started to rotate, and the rotating member 13 drives the screw to rotate, so that the screw is inserted into the threaded hole on the bracket 20 and the threaded hole on the hard disk 21. After the screw is inserted into the predetermined position, the bracket 20 and the hard disk 21 can be fixed together.

[0062] When it is necessary to disassemble the hard disk 21 from the bracket 20, the bracket 20 and the hard disk 21 are first placed on the support 11, and then the rotating member 13 is inserted into the screw between the bracket 20 and the hard disk 21. At this time, the rotating member 13 is started to rotate, and the rotating member 13 drives the screw to rotate, so that the screw can be disassembled. After the screw is disassembled, the hard disk 21 can be automatically released from the bracket 20.

[0063] In the technical solution of the embodiment of the application, the hard disk 21 is only needed to be placed on the bracket 20, and then the bracket 20 together with the hard disk 21 is placed on the support 11. At this time, under the fixation of the support 11, the corresponding fastener 22 is driven to rotate by the rotating member 13, so that the bracket 20 and the hard disk 21 can be fastened together, or the bracket 20 and the hard disk 21 that are fastened together can be released. The overall process has high automation degree and does not need manual operation of the rotating member 13 to fix each fastener 22 with the bracket 20 and the hard disk 21, and has high work efficiency. At the same time, since the worker does not need to contact the bracket 20 during the fastening or releasing process, the bracket 20 is avoided from scratching the worker.

[0064] According to some embodiments of the application, as Figure 1As shown, the support 10 comprises a bracket 11 and at least two side frames 12, wherein the bracket 11 is used to place and fix the bracket 20 and the hard disk 21, the two side frames 12 are correspondingly arranged at the two sides of the bracket 11 along a first direction, the rotating member 13 is arranged at the opposite side of the two side frames 12, and the side frame 12 can move along the first direction relative to the bracket 11, wherein the first direction is the direction in which the two side frames 12 move close to or away from each other.

[0065] In the embodiment, the first direction is the X-axis direction in the figure. Figure 1

[0066] Referring to Figure 1 As shown, the bracket 11 and the side frame 12 in the embodiment are all three-dimensional structures, which can be determined according to actual conditions, and the embodiment of the specification is not limited in this regard.

[0067] The side frame 12 in the embodiment can be connected with the bracket 11 through an electric telescopic rod, an air cylinder or the like, and in use, the side frame 12 is driven by the electric telescopic rod or the air cylinder to move close to or away from the bracket 11 along the X-axis direction.

[0068] The embodiment comprises two side frames 12, and referring to Figure 1 As shown, the two side frames 12 are correspondingly arranged at the left and right sides of the bracket 11.

[0069] The embodiment is provided with two rotating members 13 on each side frame 12, and referring to Figure 3 As shown, when the bracket 20 and the hard disk 21 are placed on the bracket 11, the screws fixed on each rotating member 13 are aligned with the corresponding threaded holes on the bracket 20 and the corresponding threaded holes on the hard disk 21. Of course, it can be understood that three, four or the like rotating members 13 can also be arranged on each side frame 12, which can be determined according to actual conditions, and the embodiment of the specification is not limited in this regard.

[0070] In the embodiment, since the side frame 12 can move along the X-axis direction relative to the bracket 11, when the bracket 20 and the hard disk 21 are placed on the bracket 11, the corresponding screws are fixed on the rotating member 13 through magnetic force or a screw cross. When the screws on the rotating member 13 are aligned with the threaded holes on the bracket 20 and the threaded holes on the hard disk 21, the side frame 12 is driven to move close to the bracket 11, and when the distance between the side frame 12 and the bracket 11 reaches a predetermined position, the rotating member 13 is started to rotate, and the rotating member 13 drives the screws to rotate. When the rotating member 13 rotates, the side frame 12 synchronously moves close to the bracket 11, and when the screws are inserted into the threaded holes on the bracket 20 and the threaded holes on the hard disk 21, the bracket 20 and the hard disk 21 can be fixed together. At this time, the rotating member 13 is closed, and at the same time, the side frame 12 stops moving close to the bracket 11.

[0071] ​When it is needed to detach the hard disk 21 from the bracket 20, first, the bracket 20 and the hard disk 21 are placed on the support 11, then the rotating member 13 is inserted into the screw between the bracket 20 and the hard disk 21, at this time, the rotating member 13 is started to rotate, at the same time, the side frame 12 is synchronized to move away from the support 11, that is, the side frame 12 drives the rotating member 13 to move away from the support 11, so that the screw can be detached. After the screw is detached, the hard disk 21 can be automatically released from the bracket 20.

[0072] Since the side frame 12 can move along the X-axis direction relative to the support 11, and the rotating member 13 is arranged on the side frame 12, when the side frame 12 moves along the X-axis direction, the rotating member 13 can be simultaneously driven to move close to or away from the support 11, so that the rotating member 13 is conveniently moved to the predetermined position.

[0073] According to some embodiments of the present application, as shown in Figure 1 , the fastening device further comprises a driving member 14 arranged on the side frame 12 and used to drive the side frame 12 to move along the first direction.

[0074] The driving member 14 in the embodiment can be an electric telescopic rod, a hydraulic rod, an air rod, etc., which can be determined according to actual conditions, and the present embodiment does not limit this.

[0075] In use, the side frame 12 can be driven to move along the X-axis direction by the driving member 14, the overall degree of automation is high, and the position of the side frame 12 is conveniently adjusted.

[0076] According to some embodiments of the present application, as shown in Figure 1 , the fastening device further comprises a telescopic rod 15 arranged between the support 11 and the side frame 12 along the first direction; wherein the driving member 14 is connected with the telescopic rod 15 and used to drive the telescopic rod 15 to elongate or shorten along the first direction.

[0077] In the embodiment, as shown in Figure 1 and Figure 4 , the telescopic rod 15 comprises a first pull rod 151 and a second pull rod 152, wherein the first pull rod 151 is fixed on the support 11 along the X-axis direction, and the second pull rod 152 is fixed on the side frame 12 along the X-axis direction. The second pull rod 152 can be inserted into the first pull rod 151 along the X-axis direction, or the second pull rod 152 can be pulled out of the first pull rod 151 along the X-axis direction.

[0078] In use, the second pull rod 152 can be driven to move relative to the first pull rod 151 along the X-axis direction by the driving member 14, for example, an electric telescopic rod, so that the side frame 12 can be driven to move close to or away from the support 11.

[0079] Since the first pull rod 151 and the second pull rod 152 are both along the X-axis direction, the side frame 12 can only move along the X-axis direction under the limitation of the first pull rod 151 and the second pull rod 152.

[0080] It should be noted that the structure of the telescopic rod is only an example, and other structures can also be used in alternative solutions, for example, the telescopic rod includes a first sliding rail and a second sliding rail, and the first sliding rail and the second sliding rail are matched through a sliding groove. The specific structure of the telescopic rod is not specially limited in the application, as long as the above structure can achieve the purpose of the application.

[0081] According to some embodiments of the application, the fastening device further comprises a first detection member (not labeled in the figure), which is electrically connected with the driving member 14 and is used for detecting the position of the telescopic rod 15.

[0082] The first detection member in the embodiment can be a limit switch, a position detection sensor, etc., and the specific type can be determined according to the actual situation, which is not limited in the embodiment.

[0083] In use, when the first detection member detects that the telescopic rod 15 is extended or shortened to a predetermined position, the first detection member sends a detected signal to the controller, and the controller controls the driving member 14 to be turned on or turned off, so that the telescopic rod 15 can be prevented from being further extended or shortened.

[0084] According to some embodiments of the application, as shown in Figure 5 The bracket 11 includes a first connecting plate 111, a second connecting plate 112 and a third connecting plate 113, wherein the first connecting plate 111, the second connecting plate 112 and the third connecting plate 113 form a triangular prism structure; the outer side of the first connecting plate 111 is used for placing and fixing the bracket 20 and the hard disk 21, and the two side frames 12 are correspondingly arranged on the two sides of the triangular prism along the axial direction of the triangular prism.

[0085] The axial direction of the triangular prism in the embodiment is the direction of the straight line L as shown in Figure 5 , wherein the direction of the straight line L is parallel to the X-axis direction.

[0086] The first connecting plate 111, the second connecting plate 112 and the third connecting plate 113 in the embodiment can be connected by welding, buckling or other means, and the specific type can be determined according to the actual situation, which is not limited in the embodiment.

[0087] In the embodiment, the first connecting plate 111, the second connecting plate 112 and the third connecting plate 113 are sequentially connected at the head and tail to form a triangular prism structure. The first pull rod 151 is fixed to the inner side of the third connecting plate 113.

[0088] When the support frame 11 is a triangular prism structure as a whole, the side frame 12 can also be a triangular prism structure. Since the triangular prism structure itself has good stability, when the support frame 11 and the side frame 12 are arranged as follows... Figure 1 When placed in the center position, the overall stability of the device can be improved. At the same time, when the bracket 20 and the hard disk 21 are placed on the first connecting plate 111, the bracket 20 and the hard disk 21 are relatively stable under the support of the triangular prism bracket 11.

[0089] It should be noted that the structure of the above-described support is merely an example. Other alternative structures can also be used, such as trapezoidal or cubic structures. This application does not impose any special restrictions on the specific structure of the support, as long as the above structure achieves the purpose of this application.

[0090] According to some embodiments of this application, such as Figure 5 As shown, a baffle 1111 is provided on the side of the first connecting plate 111 facing the second connecting plate 112. When the bracket and the hard drive are placed on the first connecting plate 111, the bracket abuts against the baffle 1111.

[0091] In this embodiment, the baffle 1111 is integrally formed with the first connecting plate 111, or the baffle 1111 is snapped onto the first connecting plate 111. The specific details can be determined according to the actual situation, and this embodiment does not limit this.

[0092] refer to Figure 5 As shown, in this embodiment, the baffle 1111 and the first connecting plate 111 are arranged at an angle. The angle between the baffle 1111 and the first connecting plate 111 can be 70°, 85°, 90°, etc., and can be determined according to the actual situation. This embodiment does not limit this.

[0093] Since a baffle 1111 is provided on the first connecting plate 111, when the bracket 20 and the hard disk 21 are placed on the first connecting plate 111, the baffle 1111 can prevent the bracket 20 from sliding off the first connecting plate 111.

[0094] According to some embodiments of this application, such as Figure 5 As shown, the fastening device also includes at least two guide rods 16, wherein the two guide rods 16 are arranged on both sides of the first connecting plate 111 along the axial direction of the triangular prism.

[0095] refer to Figure 5 As shown, the two guide rods 16 can be fixed to the left and right sides of the first connecting plate 111 by means of bolts, welding, etc. At the same time, the guide rods 16 extend along the length direction of the left side of the first connecting plate 111.

[0096] like Figure 8As shown, the bracket 20 in the embodiment includes a fixed plate 201 and two side plates 202, the side plates 202 are correspondingly fixed on opposite sides of the fixed plate 201, and one end of the side plate 202 away from the fixed plate 201 is a free end, and the one end of the side plate 202 away from the fixed plate 201 can swing freely relative to the fixed plate 201, when the bracket 20 is placed on the first connecting plate 111, at this time, under the limitation of the two guide rods 16, it can be avoided that the side plate 202 is located outside the first connecting plate 111 on the left and right sides, that is, the side plate 202 is avoided to generate relative displacement, for example, the opposite sides are not parallel to each other.

[0097] According to some embodiments of the present application, as shown in Figure 5 As shown, the fastening device further includes at least two wing plates 17, the two wing plates 17 are correspondingly arranged on the two sides of the first connecting plate 111 along the axial direction of the triangular prism, the wing plate 17 extends outward relative to the first connecting plate 111, and the wing plate 17 is located above the guide rod 16 along the second direction, wherein the second direction is the direction in which the bracket is inserted into the first connecting plate 111.

[0098] In the embodiment, as shown in Figure 5 As shown, the second direction is the Y-axis direction, wherein the included angle between the X-axis and the Y-axis can be 80°, 85°, 90°, etc., and the embodiment is described by taking the case that the X-axis and the Y-axis are perpendicular to each other as an example.

The specific mode can be determined according to actual conditions, and the embodiment of the specification is not limited in this regard.

[0104] Since the fixed net 18, the first connecting plate 111 and the baffle 1111 can surround to form the inner cavity of the fixed bracket 20, when the bracket 20 is placed on the first connecting plate 111 together with the hard disk 21, the bracket 20 and the bottom of the hard disk 21 are located in the corresponding inner cavity, avoiding the bracket 20 and the hard disk 21 from falling off the first connecting plate 111.

[0105] According to some embodiments of the present application, as shown in Figure 1 The rotating member 13 includes a first switch 132, a second switch 133 and a plurality of automatic screwing members 131, wherein the automatic screwing member 131 is used to drive the fastener 22 to rotate; wherein the first switch 132 and the second switch 133 are arranged on the side frame 12, and the plurality of automatic screwing members 131 are arranged on the opposite sides of the two side frames 12; and each automatic screwing member 131 is electrically connected with the first switch 132 and the second switch 133 respectively.

[0106] The automatic screwing member 131 in the present example is selected as an electric screwdriver, and it can be understood that the automatic screwing member 131 can also be an electric driver. For the convenience of explanation, the automatic screwing member 131 is taken as an electric screwdriver as an example in the following.

[0107] The embodiment is provided with two electric screwdrivers on the opposite sides of each side frame 12, and it can be understood that three, four or more electric screwdrivers can also be arranged on the opposite sides of each side frame 12. The specific mode can be determined according to actual conditions, and the embodiment of the specification is not limited in this regard.

[0108] The first switch 132 in the embodiment can control the electric screwdriver to rotate clockwise, and the second switch 133 can control the electric screwdriver to rotate counterclockwise. It can be understood that the first switch 132 can also control the electric screwdriver to rotate counterclockwise. The specific mode can be determined according to actual conditions, and the embodiment of the specification is not limited in this regard.

[0109] During fixing, referring to Figure 6 First, the hard disk 21 is placed on the first connecting plate 111 on the bracket 11, referring to Figure 7 When the hard disk 21 abuts against the baffle 1111 on the first connecting plate 111, referring to Figure 8 At this time, the bracket 20 is placed on the first connecting plate 111 on the bracket 11, referring to Figure 8As shown, when the fixed plate 201 on the bracket 20 abuts against the hard disk 21, the first screw hole 2021 on the side plate 202 is aligned with the second screw hole 211 on the hard disk 21. At this time, there is a gap between the automatic screwing member 131 and the side plate 202, as shown in Figure 10 As shown, the fastener 22 is then installed on the automatic screwing member 131, as shown in Figure 11 As shown, the side frame 12 is then moved towards the side plate 202 by the driving member 14. After the side frame 12 is moved towards the side plate 202, when the fastener 22 contacts the first screw hole 2021, as shown in Figure 12 As shown, the first switch 132 is pressed, the first switch 132 controls the rotation of the automatic screwing member 131, and at the same time, the driving member 14 drives the telescopic rod 15 to move, at this time, the telescopic rod 15 synchronously drives the side frame 12 to move towards the support 11. In this way, when the automatic screwing member 131 drives the fastener 22 to rotate, the driving member 14 synchronously drives the side frame 12 to move towards the support 11 through the telescopic rod 15. Since the automatic screwing member 131 is fixed on the side frame 12, at this time, when the side frame 12 moves towards the support 11, the automatic screwing member 131 can pass the corresponding fastener 22 into the first screw hole 2021 and the second screw hole 211, so as to fix the bracket 20 and the hard disk 21 together. At this time, the driving member 14 stops working, and at the same time, the automatic screwing member 131 also stops working.

[0110] When it is needed to disassemble the hard disk 21 from the bracket 20, first, the bracket 20 and the hard disk 21 are placed on the support 11 together, and then the reverse operation of the above fixing steps is installed, which will not be described here.

[0111] According to some embodiments of the present application, the fastening device further comprises a second detection member (not marked in the figure), which is arranged on the automatic screwing member 131 and is used for detecting the position of the fastener 22 on the automatic screwing member 131.

[0112] The second detection member in the embodiment can be a photoelectric sensor, a visual sensor, etc., which can be determined according to actual conditions, and the embodiments of the present application are not limited thereto.

[0113] The second detection member in the embodiment is electrically connected with the automatic screwing member 131.

[0114] In use, after the screw is fixed on the automatic screwing member 131, the second detection member can be used to detect whether the screw is aligned with the threaded hole on the bracket 20, or the position of the screw, so as to facilitate the adjustment of the position of the screw.

[0115] Of course, it can be understood that the second detection member can also be a magnetic sensor. When the screw is attracted to the bit on the automatic screwing member 131 by magnetic force, the magnetic sensor detects the magnetic force between the screw and the bit on the automatic screwing member 131. When the magnetic force is less than a preset value, the screw falls off the bit on the automatic screwing member 131.

[0116] According to some embodiments of the present application, the fastening device further comprises a third detection member (not labeled in the figure) arranged on the automatic screwing member 131 and configured to detect the output torque of the automatic screwing member 131.

[0117] The third detection member in the embodiment can be a torque sensor, which can be determined according to actual conditions, and the present application does not limit the embodiment.

[0118] The third detection member in the embodiment is electrically connected to the automatic screwing member 131.

[0119] In use, when the automatic screwing member 131 fastens the screw to the bracket 20 and the hard disk 21, the output torque of the automatic screwing member 131 is detected by the third detection member. When the preset torque value is reached, the third detection member sends the detected signal to the automatic screwing member 131, and the automatic screwing member 131 automatically stops rotating, ensuring that the screw is properly fastened, avoiding uneven force when manually fastening, causing damage to the bracket 20 and the hard disk 21, and the phenomenon of screw slippage.

[0120] According to some embodiments of the present application, as shown in Figure 3 and in combination with Figure 4 , the fastening device further comprises a base 19, which is provided with a limiting plate 191 on opposite sides in the first direction. At the same time, the bracket 11 and the side frame 12 are located in the base 19, and the side frame 12 abuts against the limiting plate 191 when the side frame 12 moves to a preset position in the first direction.

[0121] In the embodiment, the limiting plate 191 is arranged on both sides of the base 19 in the X-axis direction. When the side frame 12 moves to a preset position in the X-axis direction, the side frame 12 abuts against the limiting plate 191, which can prevent the side frame 12 from moving in the X-axis direction away from the bracket 11.
