[0001] This application relates to the field of computer technology, and particularly to a fixing device for a computer motherboard. Background Art

[0002] The computer motherboard is the core component of the computer hardware system. It is the hub connecting the CPU, memory, storage devices, graphics card, expansion cards, power supply, and other peripherals. It realizes data transmission and collaborative work between various hardware through circuits and interfaces, directly affecting the performance, stability, and expandability of the computer.

[0003] In the prior art, the computer motherboard is fixed to the inner wall of the mounting box by bolts. Since the fixed height of the computer motherboard in the mounting box limits the wiring space of the wires, the wires are squeezed or the heat dissipation is affected, thus affecting the stability of the operation of the computer motherboard. Summary of the Invention

[0004] In order to improve the problem of the fixed height of the computer motherboard in the mounting box, this application provides a fixing device for a computer motherboard.

[0005] A fixing device for a computer motherboard provided by this application adopts the following technical solution: A fixing device for a computer motherboard includes a motherboard body, a mounting box, and an adjusting component. The mounting box has an adjusting cavity for the motherboard body to slide. The adjusting component includes a fixing plate, an adjusting plate, and an adjusting screw. The adjusting screw is rotatably connected to the inner wall of the adjusting cavity. The axis of the adjusting screw is parallel to the sliding direction of the motherboard body. One end of the fixing plate is connected to the bottom of the motherboard body, and the other end of the fixing plate is connected to the plate surface of the adjusting plate. There is an adjusting space between the adjusting plate and the fixing plate. The plate surface of the adjusting plate facing the adjusting space is provided with a threaded hole for the adjusting screw to be threadedly connected. The end of the adjusting screw passes through the threaded hole and faces the adjusting space. When the adjusting plate slides along the axis of the adjusting screw, it drives the motherboard body to slide on the inner wall of the adjusting cavity.

[0006] By adopting the above technical solution, one end of the fixing plate is connected to the bottom of the motherboard body, and the other end of the fixing plate is connected to the plate surface of the adjusting plate. And the adjusting space is located between the adjusting plate and the fixing plate. Driving the adjusting screw to rotate drives the adjusting plate to slide along the axis of the adjusting screw, pushing the motherboard body to slide on the inner wall of the adjusting cavity, so that the height of the motherboard body in the adjusting cavity can be adjusted according to the wiring space of the wires. The wires are not easily squeezed, ensuring stable heat dissipation between adjacent wires, thereby improving the stability of the operation of the computer motherboard.

[0007] Optionally, the adjusting assembly further includes a guide post. The end of the guide post is connected to the bottom wall of the adjusting cavity. The axis of the guide post and the axis of the adjusting screw are parallel to each other. A guide hole for the guide post to slide is formed on the plate surface of the adjusting plate facing the adjusting space. When the main board body slides on the inner wall of the adjusting cavity, the guide post is driven to slide on the inner wall of the guide hole.

[0008] By adopting the above technical solution, when the main board body slides on the inner wall of the adjusting cavity, the guide post is driven to slide along the inner wall of the guide hole, so that the main board body is not easily offset when sliding on the inner wall of the adjusting cavity, thereby improving the stability of the main board body sliding on the inner wall of the adjusting cavity.

[0009] Optionally, a power assembly is connected between the adjusting screw and the containing box. The power assembly includes a power rod, a handwheel, a first sprocket, a second sprocket and a chain belt. A power cavity for the power rod to rotate is formed on the surface of the containing box. The power cavity communicates with the adjusting cavity. The axis of the power rod and the axis of the guide post are parallel to each other. The first sprocket is coaxially connected to the adjusting screw. The second sprocket is coaxially connected to the power rod. The chain belt is tensioned and connected to the first sprocket and the second sprocket. The handwheel is coaxially connected to the end of the power rod.

[0010] By adopting the above technical solution, the power rod is rotatably connected to the inner wall of the power cavity, and the handwheel is coaxially connected to the end of the power rod. The handwheel provides a force application point for the user. When it is necessary to adjust the position of the main board body in the adjusting cavity, hold the handwheel and rotate it to drive the power rod to rotate. The chain belt is tensioned and connected to the first sprocket and the second sprocket, driving the adjusting screw to rotate, and pushing the adjusting plate to slide along the axis of the adjusting screw, realizing precise adjustment of the height of the main board body on the inner wall of the adjusting cavity. There is no need for the staff to put their fingers into the adjusting space to drive the adjusting screw to rotate, thereby improving the simplicity of the user to adjust the height of the main board body in the adjusting cavity.

[0011] Optionally, the power rod includes a rotating part, an embedding block and a power part. The rotating part is rotatably connected to the inner wall of the power cavity. The second sprocket is coaxially connected to the outer peripheral surface of the rotating part. A sliding cavity for the power part to slide is coaxially formed on the surface of the rotating part. The embedding block is connected to the surface of the power part. An embedding groove for the embedding block to embed is formed on the inner wall of the sliding cavity. The handwheel is coaxially connected to the end of the power part protruding from the rotating part, and the end face of the handwheel is flush with the surface of the containing box.

[0012] By adopting the above technical solution, when it is necessary to adjust the position of the main board body in the adjustment cavity, hold the handwheel and drive the power part to slide along the inner wall of the sliding cavity in a direction away from the power cavity. The end of the handwheel protrudes from the surface of the bearing box, which further facilitates the user to hold and control the rotation of the power part. The surface of the insert block abuts against the inner wall of the insert groove to form a limit, stably driving the rotation part to rotate, and further improving the stability of adjusting the position of the main board body in the adjustment cavity. And when pressing the power part to slide along the inner wall of the sliding cavity in a direction close to the bearing box, the end face of the handwheel is flush with the surface of the bearing box, realizing the storage of the handwheel, so that the handwheel is not easily rotated by external impact, thereby improving the limit stability of adjusting the main board in the adjustment cavity.

[0013] Optionally, the power assembly further includes an elastic member. One end of the elastic member in the direction of the elastic force is connected to the inner wall of the sliding cavity, and the other end of the elastic member in the direction of the elastic force is connected to the surface of the power part. The elastic member has an elastic force to drive the power part to slide in a direction close to the sliding cavity, and there is a tendency for the end face of the handwheel to be flush with the surface of the bearing box.

[0014] By adopting the above technical solution, the elastic force of the elastic member drives the power part to slide in a direction close to the sliding cavity, and the end face of the handwheel is flush with the surface of the bearing box, so that the power part is not easily offset on the inner wall of the sliding cavity during the movement of the bearing box, thereby improving the limit stability of the power part in the sliding cavity.

[0015] Optionally, the power assembly further includes a limit ring bladder. An installation cavity for accommodating the limit ring bladder is provided on the inner wall of the adjustment cavity, and the inner wall of the limit ring bladder abuts against the rotating shaft of the adjustment screw to form a limit.

[0016] By adopting the above technical solution, the outer wall of the limit ring bladder abuts against the inner wall of the installation cavity, and the inner wall of the limit ring bladder abuts against the outer peripheral surface of the adjustment screw to form a limit, so that the adjustment screw is not easily rotated in the adjustment cavity, thereby improving the limit stability of the main board body in the adjustment cavity.

[0017] Optionally, an air flow channel is provided on the inner wall of the installation cavity. One end of the air flow channel communicates with the inner cavity of the limit ring bladder, and the other end of the air flow channel communicates with the sliding cavity.

[0018] By adopting the above technical solution, when it is necessary to adjust the height of the main board body in the adjustment cavity, hold the handwheel and drive the power part away from the loading box, the air pressure in the sliding cavity decreases, and the air in the inner cavity of the limiting ring bladder enters the sliding cavity through the air flow passage. The limiting effect of the inner ring wall of the limiting ring bladder on the adjusting screw disappears. Rotate the handwheel, the chain belt tightly connects the first sprocket and the second sprocket, and drives the adjusting screw to slide on the inner wall of the adjustment cavity, realizing the height adjustment of the main board body in the adjustment cavity. When the height of the main board body in the adjustment cavity reaches the preset value, release the handwheel, and the elastic force of the elastic part drives the power part to slide along the inner wall of the sliding cavity towards the direction close to the loading box. The air pressure in the sliding cavity increases, and the air in the sliding cavity enters the inner cavity of the limiting ring bladder through the air flow passage. The inner ring wall of the limiting ring bladder pressurizes and expands and abuts against the outer peripheral surface of the rotating part of the adjusting screw to form a limit, thereby improving the limiting stability of the main board body in the adjustment cavity.

[0019] Optionally, the loading box is connected with a positioning assembly, the positioning assembly includes a positioning plate and a plurality of positioning blocks. The two ends of the positioning plate are correspondingly connected to the mutually facing inner walls of the power cavity. A rotating hole for the power part to slide is formed on the plate surface of the positioning plate. The plurality of positioning blocks are spaced and connected to the surface of the positioning plate facing the handwheel. The plurality of positioning blocks are evenly distributed at intervals around the axis of the rotating hole. A plurality of positioning cavities for the positioning blocks to be embedded are correspondingly and spacedly formed on the surface of the handwheel. When the end surface of the handwheel is flush with the end surface of the loading box, the positioning blocks are correspondingly embedded in the positioning cavities to form a limit.

[0020] By adopting the above technical solution, when the elastic force of the elastic part drives the power part to slide along the inner wall of the sliding cavity towards the direction close to the loading box, the positioning blocks are correspondingly embedded in the positioning cavities, and the surfaces of the positioning blocks abut against the inner walls of the positioning cavities to form a limit, restricting the rotation of the handwheel, so that the main board body is not easily offset in the adjustment cavity, thereby improving the positioning stability of the main board body in the adjustment cavity.

[0021] Optionally, the loading box is connected with a buffer assembly, the buffer assembly includes a buffer plate and an elastic bladder. One end of the elastic bladder is connected to the inner wall of the adjustment cavity, and the other end of the elastic bladder is connected to the plate surface of the buffer plate. The elastic bladder has an elastic force to drive the buffer plate to approach the fixed plate, and the plate surface of the buffer plate abuts against the plate surface of the fixed plate to form a tendency of support.

[0022] By adopting the above technical solution, the elastic force of the elastic bladder drives the buffer plate to approach the fixed plate, and the plate surface of the buffer plate abuts against the plate surface of the fixed plate to form a support, increasing the support points for the main board body, thereby improving the limiting stability of the main board body in the adjustment cavity.

[0023] Optionally, a plurality of heat dissipation holes are formed on the surface of the loading box, and the heat dissipation holes communicate with the adjustment cavity.

The end of the fixing bolt 36 is respectively threaded and tightened and fixed on the inner wall of the fixing hole 11. The nut end surface of the fixing bolt 36 and the plate surface of the fixing plate 31 clamp both sides of the motherboard body 1 to form a fixation, realizing the detachable fixation between the motherboard body 1 and the fixing plate 31.

[0034] Referring to Figure 2 and Figure 3 , the plate surface of the fixing plate 31 facing the motherboard body 1 is provided with a heat dissipation cavity 311. The heat dissipation cavity 311 penetrates through the plate surface of the fixing plate 31 and communicates with the adjustment cavity 21. The air in the adjustment cavity 21 can impact the plate surface of the fixing plate 31 through the heat dissipation cavity 311. The air fully contacts the plate surface of the fixing plate 31 and conducts heat exchange, thereby improving the heat dissipation efficiency of the heat dissipation motherboard.

[0035] Referring to Figure 2 and Figure 3, the surface of the adjusting plate 32 is integrally formed and fixed on the surface of the fixing plate 31 facing away from the main board body 1. An adjusting space 312 is left between the adjusting plate 32 and the fixing plate 31. The adjusting space 312 communicates with the adjusting cavity 21. A threaded hole 321 for threaded connection of the adjusting screw 33 is provided on the surface of the adjusting plate 32 facing the adjusting space 312. The axis of the threaded hole 321 is parallel to the height direction of the receiving box 2. The threaded hole 321 penetrates the surface of the adjusting plate 32 along its own axis. One end of the adjusting screw 33 is rotatably connected to the inner wall of the adjusting cavity 21. The other end of the adjusting screw 33 passes through the threaded hole 321 and faces the adjusting space 312. The rotation axis of the adjusting screw 33 is parallel to the height direction of the receiving box 2. The adjusting space 312 provides space for the end of the adjusting screw 33 to be embedded, so that the end of the adjusting screw 33 is not easy to squeeze the surface of the fixing plate 31, thereby improving the stability of the main board body 1 sliding on the inner wall of the adjusting cavity 21.

[0036] Refer to Figure 2 and Figure 3 , a guide hole 322 for the guide rod to slide is provided on the surface of the adjusting plate 32 facing the adjusting space 312.

One end of the guide post 34 is fixed inside the adjusting cavity 21. The other end of the guide post 34 passes through the guide hole 322 and faces the adjusting space 312; when the adjusting screw 33 is driven to rotate, the adjusting plate 32 is driven to slide along the axis of the adjusting screw 33, driving the main board body 1 to slide on the inner wall of the adjusting cavity 21; at the same time, the guide post 34 slides along the axis of the guide hole 322, ensuring that the main board body 1 is not easy to deflect when sliding on the inner wall of the adjusting cavity 21, so that the height of the main board body 1 in the adjusting cavity 21 can be adjusted according to the wiring space of the wire, the wire is not easy to be squeezed, ensuring stable heat dissipation between adjacent wires, thereby improving the stability of the computer main board operation.

[0037] Refer to Figure 2 and Figure 4, a power assembly 4 is installed between the adjusting screw 33 and the loading box 2. The power assembly 4 can drive the adjusting screw 33 to rotate. The power assembly 4 includes a power rod 41, a handwheel 42, a first sprocket 43, a second sprocket 44, a chain belt 45, an elastic member 46 and a limiting ring capsule 47. The power rod 41 includes a rotating portion 411, an inserting block 412 and a power portion 413. In the embodiment of the present application, both the rotating portion 411 and the power portion 413 are round rods, and the inserting block 412 is a square block. A sliding cavity 4111 for the power portion 413 to slide is coaxially opened on the end surface of the rotating portion 411 in the axial direction. In the embodiment of the present application, the power portion 413 is equivalent to a piston. The inserting block 412 is connected to the surface of the power portion 413. An inserting groove 4112 for the inserting block 412 to be inserted is opened on the inner wall of the sliding cavity 4111. The surface of the inserting block 412 abuts against the inner wall of the inserting groove 4112 to form positioning. The handwheel 42 is coaxially fixed to the end of the power portion 413 protruding from the rotating portion 411. When holding the handwheel 42 to drive the power portion 413 to rotate, the rotating portion 411 is driven to rotate through the abutting effect between the inserting block 412 and the inner wall of the inserting groove 4112, thereby improving the stability of kinetic energy transmission between the power portion 413 and the rotating portion 411.

[0038] Refer to Figure 2 and Figure 3 , a power cavity 22 for the rotating portion 411 to rotate is opened on the surface of the loading box 2. The rotation axis of the rotating portion 411 is parallel to the height direction of the loading box 2. The power cavity 22 communicates with the adjusting cavity 21. The first sprocket 43 is coaxially fixed on the outer peripheral surface of the adjusting screw 33. The second sprocket 44 is coaxially fixed on the outer peripheral surface of the rotating portion 411. The chain belt 45 is tensioned and connected to the first sprocket 43 and the second sprocket 44. The elastic member 46 can be a compression spring or a tension spring. In the embodiment of the present application, the elastic member 46 is a compression spring and has a certain deformation ability. One end in the elastic force direction of the elastic member 46 is connected to the inner wall of the sliding cavity 4111, and the other end in the elastic force direction of the elastic member 46 is connected to the end surface of the power portion 413 away from the handwheel 42. The elastic member 46 has an elastic force to drive the power portion 413 to slide in the direction close to the rotating portion 411, and there is a tendency for the end surface of the handwheel 42 to be flush with the surface of the loading box 2.

[0039] Refer to Figure 2 and Figure 3 , the material of the limiting ring capsule 47 can be rubber or silica gel. In the embodiment of the present application, the material of the limiting ring capsule 47 is rubber and has a certain deformation ability. An installation cavity 23 for accommodating the limiting ring capsule 47 is opened on the inner wall of the adjusting cavity 21. The axis of the limiting ring capsule 47 coincides with the axis of the adjusting screw 33. The inner peripheral wall of the limiting ring capsule 47 abuts against the outer peripheral surface of the rotating shaft of the adjusting screw 33 to form a limit. The outer peripheral wall of the limiting ring capsule 47 abuts against the inner wall of the installation cavity 23 to form a limit. An air charging flow channel 24 is opened on the inner wall of the installation cavity 23. One end of the air charging flow channel 24 communicates with the inner cavity of the limiting ring capsule 47, and the other end of the air charging flow channel 24 penetrates through the inner wall of the adjusting cavity 21 in the direction close to the power cavity 22 and communicates with the sliding cavity 4111.

[0040] Reference Figure 2 and Figure 3 When it is necessary to adjust the position of the main board body 1 in the adjustment cavity 21, hold the handwheel 42 and drive the power part 413 to slide along the inner wall of the sliding cavity 4111 in a direction away from the rotating part 411. The handwheel 42 protrudes from the surface of the mounting box 2 for the user to hold, and the air pressure in the sliding cavity 4111 decreases. The air in the limit ring capsule 47 enters the sliding cavity 4111 through the air charging flow channel 24. The inner circumferential wall of the limit ring capsule 47 contracts due to the pressure reduction, and the limiting effect of the limit ring capsule 47 on the adjustment screw 33 disappears, driving the handwheel 42 to rotate. The surface of the insert block 412 abuts against the inner wall of the insert groove 4112, driving the rotating part 411 to rotate on the inner wall of the power cavity 22. The chain belt 45 is tensioned to connect the first sprocket 43 and the second sprocket 44, driving the adjustment screw 33 to slide on the inner wall of the adjustment cavity 21, pushing the adjustment plate 32 to slide along the axis of the adjustment screw 33, driving the main board body 1 to slide on the inner wall of the adjustment cavity 21, so that the height of the main board body 1 in the adjustment cavity 21 is adapted to the wiring space of the wire, making the wire not easily squeezed, and enabling the adjacent wires to stably and fully contact the air in the adjustment cavity 21 and conduct heat exchange, thereby improving the heat dissipation efficiency of the computer main board, and thus ensuring the stability of the operation of the main board body 1.

[0041] Reference Figure 2 and Figure 3 When the height of the main board body 1 in the adjustment cavity 21 is adapted to the wiring space of the wire, release the handwheel 42. The elastic force of the elastic part 46 drives the power part 413 to slide along the inner wall of the sliding cavity 4111 in a direction close to the rotating part 411. The air pressure in the sliding cavity 4111 increases, and the air in the sliding cavity 4111 enters the inner cavity of the limit ring capsule 47 through the air charging flow channel 24. The inner circumferential wall of the limit ring capsule 47 expands due to the increased pressure and abuts against the outer peripheral surface of the rotating shaft of the adjustment screw 33 to form a limit, making the adjustment screw 33 not easily rotate on the inner wall of the adjustment cavity 21, thereby improving the limit stability of the main board body 1 in the adjustment cavity 21.

[0042] Reference Figure 2 and Figure 3, the mounting box 2 is provided with a positioning component 5. The number of the positioning components 5 can be one, two or more. In the embodiment of the present application, the number of the positioning components 5 is two. The positioning components 5 correspond to the power chambers 22 one by one and are connected to the inner walls of the power chambers 22. The positioning components 5 can limit the rotation of the handwheel 42. The positioning component 5 includes a positioning plate 51 and a plurality of positioning blocks 52. The two ends of the positioning plate 51 in the length direction are correspondingly connected to the mutually facing inner walls of the power chamber 22. A rotation hole 511 for the power part 413 to slide is formed on the plate surface of the positioning plate 51. The axis of the rotation hole 511 coincides with the axis of the sliding chamber 4111. The rotation hole 511 penetrates through both sides of the positioning plate 51 along its own axis. The rotation hole 511 communicates with the sliding chamber 4111. And the bottom of the positioning plate 51 abuts against the end face of the rotating part 411 facing the power part 413 to form a position. A plurality of positioning blocks 52 are fixedly arranged at intervals on the end face of the positioning plate 51 facing the handwheel 42. The plurality of positioning blocks 52 are evenly distributed at intervals around the axis of the rotation hole 511. A plurality of positioning cavities 421 for the positioning blocks 52 to be inserted are correspondingly formed at intervals on the surface of the handwheel 42. The depth direction of the positioning cavity 421 is parallel to the axis of the power part 413. The positioning cavity 421 penetrates through both sides of the handwheel 42 along its own depth direction.

[0043] Referring to Figure 2 and Figure 3 , when the elastic member 46 elastically drives the power part 413 to slide along the inner wall of the sliding chamber 4111 towards the direction close to the rotating part 411, the end face of the handwheel 42 is flush with the surface of the mounting box 2. The positioning blocks 52 are correspondingly inserted into the positioning cavities 421 one by one. The surface of the positioning block 52 abuts against the inner wall of the positioning cavity 421 to form a limit. And the end face of the handwheel 42 and the end face of the rotating part 411 clamp both sides of the positioning plate 51 to form a position. By limiting the rotation of the handwheel 42, the rotation of the rotating part 411 on the inner wall of the power chamber 22 is limited, so that the adjusting screw 33 is not easy to deflect in the adjusting chamber 21, further ensuring the limit stability of the adjusting screw 33 in the adjusting chamber 21.

[0044] Referring to Figure 2 and Figure 3, a buffer assembly 6 is installed on the receiving box 2. The buffer assembly 6 can provide support for the adjusting plate 32, so that the adjusting plate 32 is not prone to flipping on the inner wall of the adjusting cavity 21. The number of the buffer assemblies 6 can be one, two or more. In the embodiment of the present application, the number of the buffer assemblies 6 is two. The two buffer assemblies 6 are respectively connected to both sides of the receiving box 2 in the width direction. The buffer assembly 6 includes a buffer plate 61 and an elastic bladder 62. The material of the elastic bladder 62 can be rubber or silica gel. In the embodiment of the present application, the material of the elastic bladder 62 is rubber, which has a certain deformation ability. One end of the elastic bladder 62 is fixed to the inner wall of the adjusting cavity 21, and the other end of the elastic bladder 62 is fixed to the plate surface of the buffer plate 61. The elastic bladder 62 has an elastic force to drive the buffer plate 61 to approach the fixing plate 31, and the plate surface of the buffer plate 61 abuts against the plate surface of the fixing plate 31 to form a supporting trend, increasing the supporting points for the main board body 1, thereby improving the stability of the main board body 1 sliding on the inner wall of the adjusting cavity 21.

[0045] Refer to Figure 2 and Figure 3 , a plurality of heat dissipation holes 25 are spaced apart on the surface of the receiving box 2. The heat dissipation holes 25 communicate with the adjusting cavity 21. External air can sequentially pass through the heat dissipation holes 25, the adjusting cavity 21 and the heat dissipation cavity 311 and impact the bottom of the main board body 1. The main board body 1 is in full contact with the air and performs heat exchange to realize the cooling of the main board body 1, thereby improving the heat dissipation efficiency of the main board body 1.

[0046] The implementation principle of a computer motherboard fixing device in an embodiment of the present application is as follows: When it is necessary to adjust the position of the motherboard body 1 in the adjustment cavity 21, hold the handwheel 42 and drive the power part 413 to slide along the inner wall of the sliding cavity 4111 in a direction away from the rotating part 411. The handwheel 42 protrudes from the surface of the mounting box 2 for the user to hold, and the air pressure in the sliding cavity 4111 decreases. The air in the limiting ring bladder 47 enters the sliding cavity 4111 through the air charging channel 24. The inner circumferential wall of the limiting ring bladder 47 contracts due to the pressure reduction, and the limiting effect of the limiting ring bladder 47 on the adjusting screw 33 disappears, driving the handwheel 42 to rotate. The surface of the insert block 412 abuts tightly against the inner wall of the insert groove 4112, driving the rotating part 411 to rotate on the inner wall of the power cavity 22. The chain belt 45 is tightly connected to the first sprocket 43 and the second sprocket 44, driving the adjusting screw 33 to slide on the inner wall of the adjustment cavity 21, pushing the adjusting plate 32 to slide along the axis of the adjusting screw 33, driving the motherboard body 1 to slide on the inner wall of the adjustment cavity 21, so that the height of the motherboard body 1 in the adjustment cavity 21 is adapted to the wiring space of the wire harness, making the wire harness not easily squeezed, and the adjacent wire harnesses can stably and fully contact the air in the adjustment cavity 21 and exchange heat, thereby improving the heat dissipation efficiency of the computer motherboard, and thus ensuring the stability of the operation of the motherboard body 1; When the height of the motherboard body 1 in the adjustment cavity 21 is adapted to the wiring space of the wire harness, release the handwheel 42. The elastic member 46 elastically drives the power part 413 to slide along the inner wall of the sliding cavity 4111 in a direction close to the rotating part 411. The air pressure in the sliding cavity 4111 increases, and the air in the sliding cavity 4111 enters the inner cavity of the limiting ring bladder 47 through the air charging channel 24. The inner circumferential wall of the limiting ring bladder 47 expands due to the increased pressure and abuts tightly against the outer peripheral surface of the rotating shaft of the adjusting screw 33 to form a limit, making the adjusting screw 33 not easily rotate on the inner wall of the adjustment cavity 21; At the same time, the positioning blocks 52 are respectively inserted into the positioning cavities 421. The surface of the positioning blocks 52 abuts tightly against the inner wall of the positioning cavities 421 to form a limit, and the end face of the handwheel 42 and the end face of the rotating part 411 clamp both sides of the positioning plate 51 to form a position. By limiting the rotation of the handwheel 42, the rotation of the rotating part 411 on the inner wall of the power cavity 22 is limited, making the adjusting screw 33 not easily deflect in the adjustment cavity 21, thereby improving the limiting stability of the motherboard body 1 in the adjustment cavity 21.

[0047] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited hereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
