[0041] See also Figures 1 to 15 As shown, in the first aspect, an embodiment of the present invention provides a node labor-saving handle device for assisting the plugging and unplugging of the node chassis 1 and the cabinet 2 of the server, including: a handle mechanism 3, a transmission plate 4, a transmission arm 5 and a fixing part 6; the handle mechanism 3 is located outside the node chassis 1 and is connected to the transmission plate 4; the transmission plate 4 is slidably set on the node chassis 1, and is provided with a guide groove 41 set upwardly inclined; the front end of the transmission arm 5 is snap-connected to the fixing part 6, the end is slidably connected to the guide groove 41, and the middle part of the transmission arm 5 is rotatably connected to the node chassis 1; the fixing part 6 is connected to the cabinet 2; when the node chassis 1 is connected to the cabinet 2, the front end of the transmission arm 5 is snap-fitted to the fixing part 6, and the end is located at the bottom of the guide groove 41; when the node chassis 1 is detached from the cabinet 2, the handle mechanism 3 drives the transmission plate 4 to partially slide out of the node chassis 1, the end of the transmission arm 5 moves to the top of the guide groove 41, and the front end is detached from the fixing part 6.

[0042] Specifically, the node-effort-saving handle device of the present invention is based on a design concept that combines the principle of a lever with a slider mechanism. The handle mechanism 3, acting as the force-applying end, transmits the relatively small external force applied by the operator through connection to the transmission plate 4. The inclined guide slot 41 on the transmission plate 4 cooperates with the end of the transmission arm 5 to form a slider structure. The middle portion of the transmission arm 5 is pivotally connected to the node chassis 1, and the front end is clipped to the fixing member 6, forming a lever structure. Through the coordinated operation of these two structures, human power is converted into a larger force sufficient to overcome the resistance between the node chassis 1 and the cabinet 2 when plugging and unplugging.

[0043] When the node chassis 1 is firmly connected to the cabinet 2, the front end of the transmission arm 5 is tightly attached to the fixing piece 6, and the rear end is at the bottom of the guide slot 41. When the node chassis 1 needs to be pulled out, the operator pulls the handle mechanism 3, driving the transmission plate 4 to slide out along the node chassis 1. The rear end of the transmission arm 5 is guided by the guide slot 41 and moves upward along the inclined direction to the top of the guide slot 41. During this process, the transmission arm 5 rotates around its center, and the front end gradually disengages from the fixing piece 6, thereby separating the cabinet 1 from the cabinet 2. During the insertion operation, the handle mechanism 3 is pushed in the reverse direction, and the rear end of the transmission arm 5 slides down along the guide slot 41, and the front end re-engages the fixing piece 6, completing the installation of the node chassis 1.

[0044] This design effectively reduces the manpower required to plug and unplug node chassis 1. Compared to traditional methods, operators only need to apply less force to complete the operation, significantly improving operational convenience and efficiency. Furthermore, the stable mechanical structure reduces the risk of damage to the equipment due to excessive manpower or improper operation, extending the service life of server node chassis 1 and cabinet 2, and reducing operation and maintenance costs.

[0045] See also Figure 6 As shown, in a specific embodiment, the node labor-saving handle device also includes an installation frame 7 connected to the node chassis 1; the transmission plate 4 is slidably set on the installation frame 7; the transmission arm 5 is located in the installation frame 7 and is rotatably connected to the installation frame 7.

[0046] Specifically, the installation frame 7 is added to provide a stable mounting platform and motion guide structure for the transmission plate 4 and transmission arm 5. The installation frame 7 is connected to the node chassis 1. The transmission plate 4 slides within the installation frame 7, and the transmission arm 5 rotates within the installation frame 7. The inner walls and structure of the installation frame 7 constrain and support the movement of the two components, ensuring that the relative positions of the components remain stable during movement, reducing shaking and offset, and improving the overall reliability of the device.

[0047] During the plugging and unplugging operation, the transmission plate 4 slides linearly in the installation frame 7 under the action of the force applied by the operator through the handle mechanism 3; the transmission arm 5 rotates in the space defined by the installation frame 7 with its rotation connection point with the installation frame 7 as the axis. The movements of both are precisely controlled by the installation frame 7, making the transmission process smoother and more orderly, and ensuring the reliable realization of the node labor-saving handle device function.

[0048] The installation of mounting frame 7 significantly improves the stability of the device, reduces friction between components caused by shaking, reduces wear, and thus extends the device's service life. Furthermore, the stable structure helps improve the precision of plugging and unplugging operations, making the plugging and unplugging process between node chassis 1 and cabinet 2 smoother, further improving the user experience and device safety.

[0049] See also Figures 7 to 11As shown, preferably, a guide member 71 is installed in the installation frame 7, and the transmission plate 4 is slidably arranged on the guide member 71. This design provides precise guidance and stable support for the sliding of the transmission plate 4 by arranging the guide member 71 in the installation frame 7, thereby ensuring the reliability and accuracy of its movement. The design of the guide member 71 is based on the principle of mechanical kinematics, and forms a precise matching structure with the transmission plate 4, limiting the freedom of movement of the transmission plate 4 so that it can only slide along a predetermined direction, avoiding unstable situations such as shaking and offset during plugging and unplugging operations. In addition, the guide member 71 can also play a positioning role for the transmission plate 4, ensuring the relative position accuracy between the transmission plate 4 and components such as the transmission arm 5 and the fixing member 6, so that the entire node labor-saving handle device can stably and efficiently transmit the force applied by the operator to the handle mechanism 3 to the node chassis 1 during operation, thereby achieving smooth plugging and unplugging of the server node chassis 1 and the cabinet 2, and improving the overall performance and operating experience of the device.

[0050] It is understandable that the mounting frame 7 is provided with a notch 72 corresponding to the fixing part 6, and the fixing part 6 extends into the mounting frame 7 from the notch 72 and forms a snap-fit ​​structure with the front end of the transmission arm 5. This design is based on the principle of spatial adaptation and connection reinforcement of mechanical structures. By providing the notch 72 in the mounting frame 7, a snap-fit ​​channel between the fixing part 6 and the transmission arm 5 is cleverly constructed. The position and size of the notch 72 precisely correspond to the shape of the fixing part 6 and the motion trajectory of the transmission arm 5, creating spatial conditions for the fixing part 6 to extend into the interior of the mounting frame 7, so that the fixing part 6 can complete the snap-fit ​​action with the front end of the transmission arm 5 without obstacles, thereby realizing a stable connection between the node chassis 1 and the cabinet 2. This open notch groove 72 design not only ensures the compactness of the buckling structure of the fixing part 6 and the transmission arm 5, but also does not affect the rotation of the transmission arm 5 in the installation frame 7 and the sliding of the transmission plate 4, ensuring that the movements of the various components do not interfere with each other; at the same time, the existence of the notch groove 72 can also guide the insertion direction of the fixing part 6 to a certain extent, reduce the difficulty of assembly, and improve the installation efficiency. In the buckled state, the notch groove 72 forms a coordinated force system with the fixing part 6 and the transmission arm 5, which enhances the stability and reliability of the overall structure during the plugging and unplugging process, and effectively prevents the connection from loosening or failure due to external forces.

[0051] See also Figures 8 to 11 As shown, in one embodiment, the handle mechanism 3 is rotatably connected to the transmission plate 4 and is detachably connected to the mounting frame 7 .

[0052] Specifically, the handle mechanism 3 is designed to be rotatably connected to the transmission plate 4 and detachably connected to the mounting frame 7 in order to optimize the operator's force application method and the storage convenience of the device. The rotatable connection allows the handle mechanism 3 to flexibly adjust its angle, making it convenient for the operator to apply force in different positions and postures; the design of being detachably connected to the mounting frame 7 allows the handle mechanism 3 to be fixed in a suitable position when not in use, avoiding shaking that affects other operations, while also making the overall structure of the device more compact and beautiful. When performing plugging and unplugging operations, the operator holds the handle mechanism 3 and rotates it, transferring force to the transmission plate 4 through the rotating connection point, driving the transmission plate 4 to move, and then realizing the plugging and unplugging of the node chassis 1; after the operation is completed, the handle mechanism 3 is rotated to the position connected to the mounting frame 7, and a detachable connection structure is adopted to firmly fix the handle mechanism 3 on the mounting frame 7, keeping the device neat and stable.

[0053] This design improves operational comfort, allowing operators to adjust the angle of handle mechanism 3 according to their preferences and operating scenarios, reducing operator fatigue. Furthermore, the detachable connection between handle mechanism 3 and mounting frame 7 enhances space efficiency, preventing interference with other devices or operations when not in operation, and improving the overall user experience.

[0054] See also Figures 8 to 13 As shown, in a specific embodiment, the handle mechanism 3 includes a handle 31 and a snap assembly 32; one end of the handle 31 is rotatably connected to the transmission plate 4, and the other end is equipped with the snap assembly 32; the snap assembly 32 is snap-connected to the mounting frame 7.

[0055] Specifically, the handle mechanism 3 is broken down into a handle 31 and a snap assembly 32, aiming to provide a clearer structure and more specific functions, facilitating the device's production, installation, and maintenance. The handle 31 acts as a force-applying component, providing a grip for the operator; the snap assembly 32 connects and secures the handle 31 to the mounting frame 7. This modular design reduces manufacturing and maintenance costs while increasing the device's versatility and interchangeability.

[0056] During the plugging and unplugging operation, the operator holds the handle 31 and applies force to drive the transmission plate 4 to move; after the operation is completed, the handle 31 is rotated to the position corresponding to the installation frame 7, and the buckle group is engaged with the installation frame 7 to firmly fix the handle 31; when it is necessary to operate again, the buckle assembly 32 is released and the handle 31 can be rotated for plugging and unplugging.

[0057] The separation of handle 31 and snap assembly 32 simplifies the structure of handle mechanism 3, reducing production complexity and costs. Furthermore, since each component has a distinct function, it can be quickly located and replaced in the event of a malfunction, improving maintenance efficiency and enhancing the overall reliability and stability of the device.

[0058] See also Figures 12 to 13 As shown, in a specific embodiment, the snap assembly 32 includes a button 321, a snap member 322 and a first elastic member 323. A first mounting groove 311 is provided on the inner side of the handle 31. The first elastic member 323 and the snap member 322 are both installed in the first mounting groove 311, and the two ends of the first elastic member 323 are respectively connected to the handle 31 and the snap member 322; the handle 31 is also provided with a guide hole 312 connected to the first mounting groove 311, one end of the button 321 is provided on the outer side of the handle 31, and the other end extends into the guide hole 312 and is transmission-connected to the snap member 322; when the snap assembly 32 is snap-connected to the mounting frame 7, the first elastic member 323 is in an initial state, and the snap member 322 partially extends out of the first mounting groove 311 and abuts against the inner side of the mounting frame 7.

[0059] Specifically, the latch assembly 32 utilizes a combination of a button 321, a latch 322, and a first elastic member 323. The elastic force of the first elastic member 323 automatically engages the latch 322, while the button 321 controls its disengagement, creating a convenient automatic locking and manual unlocking mechanism. The first elastic member 323 is mounted in a first mounting slot 311 within the handle 31, with its ends connecting the handle 31 and the latch 322, respectively. In its natural state, the first elastic member 323 partially extends the latch 322. The button 321 is in transmission connection with the latch 322 via the guide hole 312, and pressing the button 321 retracts the latch 322.

[0060] When the handle 31 is rotated to the engaged position with the mounting frame 7, under the elastic force of the first elastic member 323, the latch member 322 automatically extends and abuts against the inner side of the mounting frame 7 to achieve engagement; when the engagement needs to be released, the operator presses the button 321 on the outside of the handle 31, and the button 321 transmits force to the latch member 322 through the guide hole 312, pushing the latch member 322 to overcome the elastic force of the first elastic member 323 and retract into the first mounting groove 311, so that the latch assembly 32 is separated from the mounting frame 7, so that the handle 31 can be rotated for other operations.

[0061] This design provides a simple, reliable, and tool-free snap-on fastening method, making it quick and easy to operate and reducing operator complexity. Furthermore, the automatic snap-on function ensures the stability of the handle 31 in the fixed state, while the manual unlocking method allows for flexible operation, enhancing the device's practicality and user experience.

[0062] Preferably, a guide surface 3221 is provided on the inner side of the fastener 322. The core design principle of providing the guide surface 3221 on the inner side of the fastener 322 is based on the combination of inclined plane mechanics and an automatic guiding mechanism. When the fastener 322 needs to be fastened back to the mounting frame 7, the inclination angle of the guide surface 3221 can decompose the vertical fastening force into two components, horizontal and vertical. This mechanical design enables the fastener 322 to automatically adjust its position and slide smoothly into the fastening position at the moment of contact with the mounting frame 7 by utilizing the inclination characteristics of the guide surface 3221, without the need for the operator to precisely align, thereby greatly reducing the difficulty of fastening.

[0063] In a specific embodiment, the handle mechanism 3 further includes a second elastic member 33 , and two ends of the second elastic member 33 are respectively connected to the handle 31 and the transmission plate 4 .

[0064] Specifically, a second elastic member 33 is added to the handle mechanism 3, with its ends connecting the handle 31 and the transmission plate 4, respectively. The core design utilizes elastic potential energy to achieve automatic adjustment of the handle 31. When the snap assembly 32 is engaged with the mounting frame 7, the second elastic member 33 is compressed and stores elastic potential energy. When the snap assembly 32 is released, the second elastic member 33 releases this elastic potential energy, pushing the handle 31 out of the mounting frame 7 and causing it to rotate about its pivot point with the transmission plate 4, forming a specific angle with the transmission plate 4. This angle has been ergonomically optimized to align with the operator's natural gripping habits, greatly enhancing the ease of handling the handle 31.

[0065] After the insertion and removal operation is complete, the handle mechanism 3 snaps onto the mounting frame 7 via the snap assembly 32, compressing the second elastic member 33. To resume operation, the operator presses the button 321 of the snap assembly 32 to release the snap. The second elastic member 33 immediately releases its elastic potential energy, instantly ejecting the handle 31 from the mounting frame 7 and simultaneously rotating it to an angle with the transmission plate 4 for easy gripping. The operator can simply grasp the handle 31 and, by pushing or pulling, activate the transmission plate 4 to complete the insertion and removal of the node chassis 1.

[0066] This design significantly improves operational efficiency, eliminating the need for manual adjustment of the handle 31's angle, reducing the number of steps and saving significant time. In complex server maintenance environments, even in cramped spaces and poor lighting, operators can quickly locate and grasp the handle 31, reducing operational difficulty and enhancing the device's usability. Furthermore, the automatic adjustment of the handle 31's position enhances overall operational fluidity and user experience, providing strong support for efficient maintenance.

[0067] More specifically, a second mounting groove 313 is further defined on the inner side of the handle 31 . The second mounting groove 313 is located at one end of the handle 31 away from the latch 322 . The second elastic member 33 is mounted in the second mounting groove 313 .

[0068] From the perspective of space utilization and structural optimization, this design sets a second mounting groove 313 on the inner side of the handle 31 and arranges the second elastic member 33 therein, effectively solving the problem of limited space inside the device. The second mounting groove 313 is arranged at the end of the handle 31 away from the latch 322, making full use of the idle space of the handle 31 itself, avoiding additional space occupation in other key parts such as the transmission plate 4 and the mounting frame 7, and ensuring the overall compact structure of the device. This layout makes the connection between the second elastic member 33 and the handle 31 and the transmission plate 4 more reasonable. Under the premise of not affecting the operation of the main functional components such as the rotation of the handle 31 and the engagement of the latch 322, the second elastic member 33 realizes the automatic reset and buffering function of the handle mechanism 3, which not only meets the functional requirements of the device, but also improves the integration and rationality of the internal structure through clever space planning, so that the entire node-saving handle device can achieve efficient coordinated operation of various components within a limited space.

[0069] Preferably, the first elastic member 323 and the second elastic member 33 are springs, and the handle 31, the transmission plate 4, and the snap member 322 are all provided with fixing posts 314 at the ends corresponding to the springs, and the ends of the springs are sleeved onto the fixing posts 314. By selecting springs as the first and second elastic members 33, the snapping force of the snap assembly 32 and the resetting effect of the handle mechanism 3 can be precisely controlled. At the same time, the fixing posts 314 are provided on the handle 31, the transmission plate 4, and the snap member 322, and the spring ends are reliably fixed by utilizing an interference fit or clearance fit between the cylindrical surface and the inner diameter of the spring. This design converts the axial force of the spring into a radial clamping force, preventing the spring from shifting or falling off during operation. In addition, the combination of the fixing posts 314 and the spring forms a standardized elastic connection module, simplifying the assembly process. The spring can be quickly installed onto the fixing posts 314 through axial sleeve connection, without the need for complex tools, thereby improving production efficiency.

[0070] See also Figures 7 to 12 and Figure 15 As shown, in a specific embodiment, the transmission plate 4 is connected to a third elastic member 8 , and the third elastic member 8 is also elastically abutted against the mounting frame 7 .

[0071] Specifically, transmission plate 4 is connected to third elastic member 8, which is used to fill the gap between transmission plate 4 and mounting frame 7. Its elastic properties ensure that transmission plate 4 remains stable and prevents wobble during sliding. As transmission plate 4 slides within mounting frame 7, third elastic member 8 elastically deforms according to the position of transmission plate 4. Its elastic force tightly adheres to transmission plate 4 and mounting frame 7, filling the gap and ensuring stable sliding of transmission plate 4.

[0072] During the plugging and unplugging operation, when the operator drives the transmission plate 4 to slide in the installation frame 7 through the handle mechanism 3, a gap will be generated between the transmission plate 4 and the installation frame 7 due to factors such as manufacturing tolerances and motion wear. At this time, the third elastic member 8, under the action of its own elastic force, tightly squeezes the transmission plate 4 and the inner wall of the installation frame 7 to eliminate the gap. No matter which direction the transmission plate 4 slides, the third elastic member 8 can adjust the elastic force in real time to ensure that the transmission plate 4 is always in a stable state without shaking or offsetting, thereby ensuring the smoothness and accuracy of the transmission process. The application of the third elastic member 8 effectively solves the problem of the transmission plate 4 being prone to shaking during the sliding process, and significantly improves the sliding stability and reliability of the transmission plate 4. The stable movement of the transmission plate 4 makes the operation of the entire handle device more precise, reduces the wear and failure probability of components caused by the shaking of the transmission plate 4, extends the service life of the device, and also improves the safety and efficiency of the plugging and unplugging operation of the server node chassis 1.

[0073] In a specific embodiment, the third elastic member 8 is a spring, including a connecting portion 81 and a deformable portion 82 connected to the connecting portion 81 . The connecting portion 81 is connected to the transmission plate 4 , and the deformable portion 82 abuts against the mounting frame 7 .

[0074] Specifically, the spring-type structure takes up less space than a coil spring, making it particularly suitable for the confined spaces within servers. The height of the spring's deformable portion 82 in its free state is slightly greater than the gap between the transmission plate 4 and the mounting frame 7. When installed in the device, the deformable portion 82 undergoes elastic compression, generating a preload perpendicular to the surface of the mounting frame 7, filling the gap and eliminating wobbling. The deformable portion 82 can be designed to have a wavy or curved shape, forming multiple contact points with the mounting frame 7. This distributed support structure effectively disperses stress, preventing wear caused by excessive local pressure, while providing more stable support.

[0075] Preferably, a positioning groove 42 is provided on the transmission plate 4; the connecting portion 81 is attached to and connected to the inner surface of the positioning groove 42; the deformation portion 82 is arranged in an arc shape, and partially protrudes from the positioning groove 42 and abuts against the mounting frame 7; the end of the deformation portion 82 away from the connecting portion 81 is also connected to a contact portion 83, and the contact portion 83 is suspended in the positioning groove 42.

[0076] This design achieves precise control and stable support for the third elastic member 8 through the coordinated action of the positioning groove 42, the arc-shaped deformation portion 82 and the contact portion 83. The setting of the positioning groove 42 provides a precise installation reference for the connecting portion 81, ensuring that the relative position of the spring piece and the transmission plate 4 is fixed, avoiding performance fluctuations caused by assembly errors. The design of the arc-shaped deformation portion 82 enables it to produce uniform elastic deformation when subjected to force, which can not only provide sufficient preload to fill the gap between the transmission plate 4 and the mounting frame 7, but also optimize the stress distribution through the arc structure, thereby extending fatigue life. The suspended design of the contact portion 83 forms a secondary elastic support mechanism. When the transmission plate 4 is subjected to lateral force, the contact portion 83 can contact the inner wall of the positioning groove 42, providing additional damping and support, and effectively suppressing shaking. This design organically combines the positioning accuracy, support stability and buffering performance of the elastic element to achieve maximum structural efficiency within a limited space.

[0077] It can also be understood that, in other embodiments, the first elastic member 323 , the second elastic member 33 and the third elastic member 8 may all adopt other elastic member structures as needed.

[0078] See also Figure 12 and Figure 14 As shown, in a specific embodiment, the transmission plate 4 is further connected to a guide cam 43 , and a stopper 44 is provided at one end of the guide cam 43 close to the transmission plate 4 . The handle 31 is rotatably connected to the guide cam 43 , and the stopper 44 is used to limit the rotation angle of the handle 31 .

[0079] Specifically, this design, based on the principles of mechanical motion constraint and force transmission optimization, precisely controls the rotational stroke and angular range of the handle 31 through the coordinated action of a guide cam 43 and a stopper 44. The guide cam 43 serves as the connecting link between the transmission plate 4 and the handle 31, while the stopper 44 near one end of the transmission plate 4 forms a physical stop. When the handle 31 rotates about the guide cam 43 to a set angle, the stopper 44 contacts the handle 31 and generates a blocking force, restricting further rotation of the handle 31. This limits the rotational angle of the handle 31 to a safe and user-friendly range. Preferably, the rotational angle of the handle 31 ranges from 0 to 90 degrees.

[0080] See also Figures 8 to 12 As shown, in a specific embodiment, the end of the transmission arm 5 is connected to a transmission shaft 51 ; the transmission shaft 51 also extends into the guide groove 41 , and a buffer ring 52 is provided on the outer periphery, and the buffer ring 52 is slidably connected to the guide groove 41 .

[0081] Specifically, the end of the transmission arm 5 is rollingly connected to the transmission shaft 51. The rotating connection design of the transmission shaft 51 converts the sliding friction between the transmission arm 5 and the guide groove 41 into rolling friction, reducing friction. The provision of the buffer ring 52 further reduces friction and noise, while also acting as a buffer during the movement of the transmission arm 5, improving the smooth operation of the device.

[0082] During insertion and removal, the transmission arm 5 rotates around its center, driving the transmission shaft 51 at its end to roll within the guide groove 41. The buffer ring 52 on the outer periphery of the transmission shaft 51 contacts the inner wall of the guide groove 41. During the rolling process, the buffer ring 52 absorbs impact and vibration through its own elastic deformation, reducing friction and wear between the transmission shaft 51 and the guide groove 41, making the movement of the transmission arm 5 smoother and more stable.

[0083] This design significantly reduces friction and noise during the movement of the transmission arm 5, improving the operating efficiency and service life of the device. Furthermore, the cushioning effect of the buffer ring 52 reduces vibration caused by movement, making the insertion and removal of the node chassis 1 smoother, enhancing operational comfort and device reliability. It will be appreciated that in other embodiments, the end of the transmission arm 5 and the transmission shaft 51 may also be fixedly connected.

[0084] In a specific embodiment, the front end of the transmission arm 5 is provided with a first clamping portion 53 and a second clamping portion 54, and a clamping slot 55 is formed between the first clamping portion 53 and the second clamping portion 54; when the end of the transmission arm 5 is located at the bottom end of the guide groove 41, the fixing member 6 extends into the clamping slot 55; when the end of the transmission arm 5 is located at the top end of the guide groove 41, the fixing member 6 is disengaged from the clamping slot 55.

[0085] The front end of the transmission arm 5 is provided with a first engaging portion 53 and a second engaging portion 54, forming a slot 55. This slot 55 cooperates with the fixing member 6 to achieve snap-on connection and disconnection. The design principle is to control the connection between the node chassis 1 and the cabinet 2 through precise mechanical coordination. The shape and size of the slot 55 are compatible with the fixing member 6. When the end of the transmission arm 5 is in different positions, the relative position of the fixing member 6 and the slot 55 changes, thereby achieving snap-on and disconnection.

[0086] When the node chassis 1 is inserted into the cabinet 2, the end of the transmission arm 5 is located at the bottom of the guide groove 41. At this time, the fixing part 6 is accurately extended into the card slot 55, and the first card portion 53 and the second card portion 54 clamp the fixing part 6, so that the front end of the transmission arm 5 and the fixing part 6 are firmly engaged, ensuring the stable connection between the node chassis 1 and the cabinet 2; when the node chassis 1 needs to be pulled out, the operator pulls the handle mechanism 3, and the end of the transmission arm 5 moves upward along the guide groove 41 to the top. During this process, the transmission arm 5 rotates, causing the fixing part 6 to gradually disengage from the card slot 55, thereby releasing the connection between the node chassis 1 and the cabinet 2.

[0087] This slot-type connection design provides a simple and reliable method for connecting and disconnecting, with a compact structure and easy operation. The precise fit between the fixing member 6 and the slot 55 ensures the stability of the connection between the node chassis 1 and the cabinet 2, effectively preventing the node chassis 1 from loosening or falling off during use, while facilitating quick plug-in and unplug operations and improving work efficiency.

[0088] See also Figures 1 to 5 As shown, in the second aspect, an embodiment of the present invention provides a server, including the above-mentioned node labor-saving handle device, a node cabinet 1 and a cabinet 2, one end of the cabinet 2 is provided with an opening 21, and the other end is provided with a first terminal 22; one end of the node chassis 1 is connected to the second terminal 11, and the node labor-saving handle device is connected to the other end of the node chassis 1; the node chassis 1 is inserted into the cabinet 2 through the opening 21; when the handle mechanism 3 is pushed and pulled, the first terminal 22 and the second terminal 11 form a detachable plug-in.

[0089] The aforementioned node labor-saving handle device is applied to servers, combined with the structural design of cabinet 2 and node chassis 1, to facilitate the convenient installation and removal of server nodes. Cabinet 2 has an opening 21 at one end for inserting node chassis 1, and a first terminal 22 at the other end. Node chassis 1 is connected to a second terminal 11 at one end, and the node labor-saving handle device is installed at the other end. The handle device's mechanical transmission allows node chassis 1 to be inserted and removed from cabinet 2, while ensuring reliable electrical connection and disconnection between first terminal 22 and second terminal 11.

[0090] When installing a server node, the operator grasps the handle mechanism 3 and slowly inserts the node chassis 1 through the opening 21 of the cabinet 2. During the insertion process, the front end of the transmission arm 5 gradually engages the fixing member 6, and the first terminal 22 and the second terminal 11 gradually align and connect. When the node chassis 1 is fully inserted, the transmission arm 5 securely engages, and a stable electrical connection is established between the first terminal 22 and the second terminal 11. To remove the node chassis 1, the operator pulls the handle mechanism 3, and the front end of the transmission arm 5 disengages the fixing member 6, causing the first terminal 22 to separate from the second terminal 11. At this point, the handle mechanism 3 is continued to be pulled to remove the node chassis 1 from the opening 21 of the cabinet 2.

[0091] This design organically integrates the node's labor-saving handle with the server structure, significantly improving server node installation and maintenance efficiency and reducing the workload of operators. Furthermore, the reliable terminal plug-in design ensures the stability and reliability of the electrical connection, ensuring normal server operation, improving overall server performance and maintainability, and possessing excellent market application value.

[0092] In one embodiment, the node chassis 1 is provided with a bracket (not shown) corresponding to the fixing member 6. After the front end of the transmission arm 5 is disengaged from the fixing member 6, the handle mechanism 3 is further pulled to remove the node chassis 1 from the opening 21 of the cabinet 2. During this process, the fixing member 6 abuts against the bracket.

[0093] The abutment between the bracket and the fixing part 6 forms a temporary support structure, which keeps the node chassis 1 stable during the extraction process, prevents shaking or deviation due to uneven force, and ensures that the node chassis 1 can be smoothly removed from the opening 21 of the cabinet 2 in a straight line. At the same time, it reduces the difficulty of the operator's force application, improves the smoothness and safety of the plug-in and unplugging operations, and ensures the efficiency and reliability of the server node maintenance process.

[0094] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the scope of protection of the present invention.
