Description

Technical Field

[0001] This utility model relates to the technical field of automatic loading and unloading equipment for metal quenching, and more specifically, it relates to an automatic loading and unloading equipment for metal quenching. Background Technology

[0002] With the development of modern manufacturing, automatic loading and unloading equipment for metal quenching, as a key piece of equipment for quenching metal workpieces, plays an extremely important technical support role. It is widely used in various metal heat treatment processes such as quenching and cooling, heat treatment, and surface quality improvement for various disc-shaped, ring-shaped, and round metal workpieces, including automotive wheel hubs, brake discs, and flywheels. Existing technologies typically use clamping frames in conjunction with lifting frames to hold and support disc-shaped metal workpieces, and use external drive components such as hydraulic drive devices to achieve automated lifting and smooth movement. This realizes a complete automated heat treatment process, including automatic loading and unloading, quenching and cooling, process conversion, and production flow for metal workpieces. While these traditional automatic loading and unloading methods can meet certain technical requirements in terms of basic clamping and fixing, they are less suitable for different specifications and applications. Metal workpieces of the same model but from different batches exhibit significant differences in technical characteristics such as outer diameter, inner diameter parameters, and thickness specifications. Existing technologies cannot provide convenient tool-free adjustments based on the specific workpiece's geometry and clamping requirements. The clamping frame position adjustment process requires specialized auxiliary equipment such as Allen wrenches, adjustable wrenches, and other special tools, making the adjustment steps complex and cumbersome. This affects production efficiency and equipment utilization. When the model and specifications of the specialized adjustment tools do not meet the equipment configuration requirements, the number of tools is insufficient, the tools are worn or damaged, or the tools are accidentally lost, it can easily lead to the inability to complete the clamping frame position adjustment of the automatic loading and unloading equipment for metal quenching in a timely manner. This affects the normal operation of the quenching production line and the timely completion of the production plan, resulting in adverse consequences such as significantly reduced production efficiency, extended equipment downtime, and increased production costs.

[0003] Secondly, although some improved automatic loading and unloading equipment for metal quenching has achieved tool-free and convenient adjustment functions through the establishment of some technical devices, the overall structural design of the tool-free adjustment system and convenient control mechanism of these improved automatic loading and unloading equipment for quenching lacks sufficient long-term reliability assurance measures. The stability is seriously lacking and is easily affected by various complex external forces such as mechanical impacts from the loading and unloading of heavy metal workpieces, repeated load changes caused by the loosening of workpiece clamping, and vibration impacts from the start and stop of the equipment. This can lead to structural loosening and even structural failures such as the accidental detachment of positioning components. As a result, the position adjustment function and stable locking ability of the clamping frame are lost. This not only seriously affects the overall clamping and positioning effect of the automatic loading and unloading equipment for metal quenching, reducing the success rate and process quality of quenching operations, but may also cause workpiece clamping failure leading to accidental falling damage, equipment failure affecting normal production, forced interruption of quenching operations, and safety risks to operators. There are even serious safety risks such as equipment damage caused by improper clamping of heavy workpieces, safety accidents caused by falling high-temperature workpieces, and significant economic losses due to production line shutdown.

A push spring is movably sleeved on the outer side of the locking sleeve, with its two ends connected to the rotating sleeve and the locking sleeve respectively. Multiple moving blocks are movably provided on one side of the releasing sleeve, and a moving block is sleeved on the outer side of the locking sleeve. The movable sleeve has an interactive plate fixedly connected to one side, a horizontal plate fixedly connected to one side of the interactive plate, and three horizontal plates. A configuration plate is rotatably provided on the outer side of the snap-fit ​​sleeve, and a configuration slot is opened on the configuration plate. A moving spring is provided between the moving blocks, and the two ends of the moving spring are respectively connected to two adjacent moving blocks. Multiple locking blocks are fixedly provided on the outer side of the snap-fit ​​sleeve. A flexible groove is opened on the inner side of the rotating sleeve, and a flexible block is movably arranged in the flexible groove. A snap-fit ​​bracket is connected to one side of the flexible block. A snap-fit ​​groove is opened on the outer side of the snap-fit ​​rod. One end of the snap-fit ​​bracket passes through the snap-fit ​​sleeve and snaps into the snap-fit ​​groove. The inner wall of the flexible groove and the outer wall of the flexible block are both designed with a chamfered structure.

[0006] The present invention is further configured such that both the clamping frame and the lifting frame are provided with adjustment holes, a plurality of adjustment holes are provided on the lifting frame, and a lifting ring is fixedly provided at the top of the lifting frame.

[0007] The present invention is further configured such that a guide rail is fixedly provided on the outer side of the snap-fit ​​sleeve, the guide rail is aligned with the flexible block, and the guide rail is located in the flexible groove.

[0008] The present invention is further configured such that a support spring is movably sleeved on the outer side of the snap-fit ​​sleeve, and one end of the support spring is connected to the movable sleeve.

[0009] The present invention is further configured such that a plurality of flexible springs are connected to one side of the flexible block, and the other end of the flexible springs is connected to the outer wall of the snap-fit ​​sleeve.

[0011] The present invention is further configured such that a thrust bearing is detachably provided on one side of the configuration plate, and the other end of the support spring is connected to the thrust bearing.

[0012] The present invention is further configured such that a rotating wheel is provided on one side of the moving block, and the rotating wheel is engaged between two adjacent locking blocks.

[0013] (III) Beneficial Effects Compared with the prior art, this utility model provides an automatic loading and unloading device for metal quenching, which has the following beneficial effects: 1. By coordinating multiple components such as the lifting frame, clamping frame, snap-fit ​​rod, snap-fit ​​sleeve, releasing sleeve, top block, rotating sleeve, inclined block, flexible slot, flexible block, snap-fit ​​frame, and snap-fit ​​groove, a tool-free and convenient position adjustment system is constructed. This solves the serious technical limitations of existing automatic metal quenching loading and unloading equipment, which lacks flexibility and adaptability in the clamping frame position adjustment mechanism and cannot quickly and conveniently adjust according to the specific workpiece's geometric dimensions, clamping requirements, and other technical parameters without tools. When it is necessary to adjust the clamping position of metal workpieces of different specifications, models, batches, outer diameters, inner diameters, and thicknesses, the operator can first perform a simple forward rotation and pulling operation to disassemble the snap-fit ​​sleeve and snap-fit ​​rod, and then adjust the position of the clamping frame. This eliminates the need for traditional automatic metal quenching loading and unloading equipment. This technology overcomes the limitations of traditional methods that rely on specialized tools such as hex wrenches, adjustable wrenches, and other specialized equipment for flexible and convenient adjustment of the clamping frame position. It avoids the complex and time-consuming adjustment steps caused by relying on these tools, and also prevents issues such as the inability to promptly adjust and calibrate the clamping frame position of the automatic metal quenching loading and unloading equipment when specialized adjustment tools are incompatible with the equipment configuration, insufficient in quantity, worn or damaged, or accidentally lost. This avoids disruptions to the normal operation of the quenching production line and the timely completion of production plans. Free from the rigid constraints of specialized tools, it allows for rapid adjustment and convenient fixing of the clamping frame position for metal workpieces of different specifications through simple manual operation steps, improving production efficiency and equipment adaptability.

[0014] 2. Through the comprehensive coordination of multiple mechanical locking and structural stabilization measures, including the rotational connection between the moving block and the rotating wheel, the locking engagement between the rotating wheel and the locking block, the rotational control between the configuration plate and the configuration slot, the linkage transmission between the moving sleeve and the interactive plate, the positioning fit between the transverse plate and the configuration slot, the elastic support of the support spring and the thrust bearing, and the elastic pulling of the moving spring and the moving block, an impact-resistant and anti-loosening safety system is constructed. This enhances the overall structural stability and connection reliability of the system, improves its vibration resistance and resistance to external interference, and effectively resists the strong mechanical impact generated during the loading and unloading of heavy metal workpieces during long-term and frequent use of automatic loading and unloading equipment for metal quenching, as well as the repeated load changes caused by the loosening of workpiece clamping. It mitigates the adverse effects of vibration and shock caused by start-up and shutdown, and solves the structural defects of some existing improved automatic metal quenching loading and unloading equipment, such as overly simple and crude overall structural design of the tool-free adjustment system and convenient control mechanism, lack of sufficient long-term reliability guarantee measures, resulting in poor resistance to impact vibration and external interference. It prevents defects such as displacement and loosening of connecting parts, or even detachment of the fixed structure, and ensures reliable connection and stable fixation between the clamping sleeve and the clamping rod for a long time, maintaining stable clamping accuracy and quenching operation quality. It meets the strict technical requirements of automatic metal quenching loading and unloading equipment for high strength, high stability, and long-term safe and reliable operation of the clamping adjustment system.

[0020] Please see Figures 1-5 An automatic loading and unloading device for metal quenching includes a lifting frame 1, a clamping frame 2 detachably mounted below the lifting frame 1, a locking rod 3 on the outside of the clamping frame 2, a locking sleeve 4 detachably mounted on the outside of the locking rod 3, a releasing sleeve 5 rotatably mounted on the outside of the locking sleeve 4, a top block 6 fixedly mounted on the outside of the releasing sleeve 5, a rotating sleeve 7 slidably mounted on the outside of the locking sleeve 4, and an inclined block 8 fixedly mounted on the outside of the rotating sleeve 7. Both the inclined block 8 and the top block 6 are of inclined structure design. A push spring 9 is movably mounted on the outside of the locking sleeve 4, with its two ends connected to the rotating sleeve 7 and the locking sleeve 4 respectively. Multiple moving blocks 10 are movably mounted on one side of the releasing sleeve 5. A moving sleeve 11 is mounted on the outside of the locking sleeve 4, and an interactive plate 1 is fixedly connected to one side of the moving sleeve 11. 2. A horizontal plate 13 is fixedly provided on one side of the interactive board 12. The horizontal plate 13 has three locations. A configuration plate 14 is rotatably provided on the outside of the snap-fit ​​sleeve 4. A configuration slot 15 is provided on the configuration plate 14. A moving spring 16 is provided between the moving blocks 10. The two ends of the moving spring 16 are respectively connected to two adjacent moving blocks 10. Multiple locking blocks 17 are fixedly provided on the outside of the snap-fit ​​sleeve 4. A flexible groove 18 is provided on the inside of the rotating sleeve 7. A flexible block 19 is movably provided in the flexible groove 18. A snap-fit ​​bracket 20 is connected to one side of the flexible block 19. A snap-fit ​​groove 21 is provided on the outside of the snap-fit ​​rod 3. One end of the snap-fit ​​bracket 20 passes through the snap-fit ​​sleeve 4 and snaps into the snap-fit ​​groove 21. The inner wall of the flexible groove 18 and the outer wall of the flexible block 19 are both designed with a chamfered structure.

[0021] Both the clamping frame 2 and the lifting frame 1 are provided with adjustment holes 22. Multiple adjustment holes 22 are provided on the lifting frame 1. A lifting ring 23 is fixedly provided at the top of the lifting frame 1.

[0022] In this embodiment, when the position of the clamping frame 2 needs to be selected, the configuration plate 14 is first rotated forward, causing the configuration plate 14 to drive the configuration slot 15 and the thrust bearing 29 on one side to rotate forward. When the configuration slot 15 is just rotated to a position concentric with the transverse plate 13, the moving sleeve 11 is pushed, causing the moving sleeve 11 to drive the interactive plate 12 on one side and the transverse plate 13 to gradually slide into the configuration slot 15. At the same time, the moving sleeve 11 and the thrust bearing 29 cooperate to compress the support spring 25. When the support spring 25 is compressed to its limit, the transverse plate 13 closest to the moving sleeve 11 just passes through the configuration slot 15 and... Move to the other side of the configuration plate 14, then rotate the configuration plate 14 in the opposite direction, causing the configuration plate 14 to drive the configuration groove 15 and the thrust bearing 29 on one side to rotate and reset in the opposite direction, so that the configuration groove 15 rotates and resets to a position that does not correspond to the transverse plate 13. Then, the interactive plate 12 and the transverse plate 13 closest to the moving sleeve 11 cooperate to limit the moving sleeve 11 to one side of the configuration plate 14, so that the moving sleeve 11 gradually no longer limits the outer wall of the rotating wheel 30. Then, rotate the sleeve 5 in the forward direction to release the sleeve 5. Releasing the sleeve 5 will drive multiple guide rails 27 on one side to rotate in the forward direction. Then, the guide rails 27 drive the moving block 10 through the guide groove 28. The device rotates forward, and then the moving block 10 drives one side wheel 30 to roll out between the two adjacent locking blocks 17. The wheel 30 then drives the moving block 10 and its inner guide groove 28 to slide outward along the guide rail 27, causing the moving block 10 to stretch the moving spring 16 outward. Simultaneously, releasing the sleeve 5 causes the outer top block 6 to rotate forward. Due to the special structural design of the top block 6 and the inclined block 8, when the top block 6 rotates forward, the push spring 9 resets and pushes the rotating sleeve 7, causing the rotating sleeve 7 to gradually slide along the guide rail 24. The rotating sleeve 7 also drives the inclined block 8 to move, ensuring that one side of the inclined block 8 remains in close contact with the top block 6. Then, the device rotates... The flexible groove 18 inside the sleeve 7 no longer limits the outer wall of the flexible block 19. Then, multiple flexible springs 26 simultaneously reset and push the flexible block 19, causing the flexible block 19 to move one side of the snap-fit ​​bracket 20 outward. Then, one end of the snap-fit ​​bracket 20 will gradually slide out of the snap-fit ​​groove 21. Then, the snap-fit ​​sleeve 4 is pulled to one side, and the snap-fit ​​rod 3 is pulled to the other side to separate the snap-fit ​​sleeve 4 and the snap-fit ​​rod 3. Then, the other snap-fit ​​sleeves 4 and snap-fit ​​rods 3 are separated according to the above steps. Then, the position of the clamping frame 2 can be moved so that the adjustment hole 22 opened on the clamping frame 2 is concentrically aligned with the corresponding adjustment hole 22 on the lifting frame 1.

[0023] Please see Figures 3-5 As a further implementation of the overall equipment: a guide rail 24 is fixedly provided on the outside of the snap-fit ​​sleeve 4. The guide rail 24 is aligned with the flexible block 19 and is located in the flexible groove 18.

[0024] A support spring 25 is movably fitted on the outer side of the snap-fit ​​sleeve 4, and one end of the support spring 25 is connected to the movable sleeve 11.

[0025] Multiple flexible springs 26 are connected to one side of the flexible block 19, and the other end of the flexible spring 26 is connected to the outer wall of the snap-fit ​​sleeve 4.

[0026] Multiple guide rails 27 are fixedly provided on one side of the loosening sleeve 5, and a guide groove 28 is provided in the moving block 10. The moving block 10 is slidably installed to the outside of the guide rails 27 through the guide groove 28.

[0027] A thrust bearing 29 is detachably mounted on one side of the configuration plate 14, and the other end of the support spring 25 is connected to the thrust bearing 29.

[0028] A rotating wheel 30 is provided on one side of the movable block 10, and the rotating wheel 30 is engaged between two adjacent locking blocks 17.

[0029] More specifically, after the clamping frame 2 is properly positioned, the locking rod 3 first passes through the pre-drilled mounting holes on the clamping frame 2 and the lifting frame 1 from one side. Then, the locking sleeve 4 is fitted onto the outside of the locking rod 3 from the other side. Next, the loosening sleeve 5 is rotated in the opposite direction, causing multiple guide rails 27 on one side to rotate in the opposite direction. The guide rails 27, in conjunction with the guide groove 28, then drive the moving block 10 and the rotating wheel 30 to rotate in the opposite direction. Simultaneously, the loosening sleeve 5 causes the outer top block 6 to rotate in the opposite direction and reset. The top block 6 then pushes the inclined block 8 to one side, causing the inclined block 8 to slide and reset. The inclined block 8 then drives the rotating sleeve 7 to slide and reset along the guide rail 24, and the rotating sleeve 7 also drives the inner flexible groove 18 to slide and reset. Because the flexible groove 18... The inner wall of the flexible block 19 is chamfered on one side, and the outer wall of the flexible block 19 is chamfered on the other side. Then, the inner wall of the flexible groove 18 gradually presses the flexible block 19 inward, so that the flexible block 19 moves inward and resets. The flexible block 19 will also compress the flexible spring 26 on one side, so that the flexible block 19 drives the locking bracket 20 on one side to gradually lock into the locking groove 21. At the same time, the rotating sleeve 7 will compress the push spring 9. When the sleeve 5 is released and fully reset, one end of the locking bracket 20 is reinserted into the locking groove 21, forming a locking relationship. At this time, the guide rail 27 drives the moving block 10 and the rotating wheel 30 to rotate and reset between the two locking blocks 17 through the guide groove 28. Then, the moving spring 16 resets and pulls the moving block 10, so that the moving block 10 drives the guide groove 28 along the guide rail 28. 7. Slide the sliding plate 14 inward to reset, and the moving block 10 will drive the one-side rotating wheel 30 to re-engage between the two original locking blocks 17. Then, rotate the configuration plate 14 forward again, causing the configuration plate 14 to drive the configuration groove 15 and the one-side thrust bearing 29 to rotate forward again. When the configuration groove 15 rotates to the position concentric with the transverse plate 13, the support spring 25 resets and pushes the moving sleeve 11, causing the moving sleeve 11 to drive the one-side interactive plate 12 and the three transverse plates 13 to slide and reset. When the support spring 25 is fully reset, the other two transverse plates 13 just move back to the two sides of the configuration plate 14 respectively. Then, rotate the configuration plate 14 in reverse again, causing the configuration plate 14 to drive the configuration groove 15 and the one-side thrust bearing 29 to rotate in the opposite direction. The configuration slot 15 is reset so that it rotates back to a position that does not correspond to the interactive plate 12 and the horizontal plate 13. Then, the interactive plate 12, in conjunction with the two corresponding horizontal plates 13, limits and supports the movable sleeve 11 to one side of the configuration plate 14, making it impossible for the movable sleeve 11 to slide easily. Then, the inner wall of the movable sleeve 11 will again limit the outer wall of the rotating wheel 30, making it impossible for the rotating wheel 30 and the movable block 10 to slide outward. The rotating wheel 30 and the movable block 10, in conjunction with the locking block 17, are rotated and limited to prevent the loose sleeve 5 from rotating accidentally, thereby achieving a convenient and stable connection. Then, the other snap-fit ​​sleeves 4 and snap-fit ​​rods 3 are snapped together according to the above steps, thereby achieving convenient adjustment of the position of the clamping frame 2, while ensuring the fixed stability of the clamping frame 2.

[0030] In summary, during the use or operation of the overall equipment: when it is necessary to select the position of the clamping frame 2, firstly, rotate the configuration plate 14 in the forward direction, causing the configuration plate 14 to drive the configuration slot 15 and the thrust bearing 29 on one side to rotate in the forward direction. When the configuration slot 15 is just rotated to a position concentric with the transverse plate 13, push the moving sleeve 11, causing the moving sleeve 11 to drive the interactive plate 12 on one side and the transverse plate 13 to gradually slide into the configuration slot 15. At the same time, the moving sleeve 11 and the thrust bearing 29 will cooperate to compress the support spring 25. When the support spring 25 is compressed to its limit, the transverse plate 13 closest to the moving sleeve 11 just passes through. The device moves through the configuration slot 15 and to the other side of the configuration plate 14. Then, the configuration plate 14 is rotated in the opposite direction, causing the configuration plate 14 to drive the configuration slot 15 and the thrust bearing 29 on one side to rotate and reset in the opposite direction. This causes the configuration slot 15 to rotate and reset to a position that does not correspond to the transverse plate 13. Then, the interactive plate 12 and the transverse plate 13 closest to the moving sleeve 11 cooperate to limit the moving sleeve 11 to one side of the configuration plate 14, so that the moving sleeve 11 gradually stops limiting the outer wall of the rotating wheel 30. Then, the sleeve 5 is rotated in the forward direction to release it. Releasing the sleeve 5 will drive multiple guide rails 27 on one side to rotate in the forward direction. Then, the guide rails 27 drive the moving sleeve 30 through the guide slot 28. The movable block 10 rotates forward, then drives one side of the rotating wheel 30 to roll out between the two adjacent locking blocks 17. The rotating wheel 30 then drives the movable block 10 and its inner guide groove 28 to slide outward along the guide rail 27, causing the movable block 10 to stretch the movable spring 16 outward. Simultaneously, releasing the sleeve 5 causes the outer top block 6 to rotate forward. Due to the special structural design of the top block 6 and the inclined block 8, when the top block 6 rotates forward, the push spring 9 resets and pushes the rotating sleeve 7, causing the rotating sleeve 7 to gradually slide along the guide rail 24. The rotating sleeve 7 also drives the inclined block 8 to move, ensuring that one side of the inclined block 8 remains in close contact with the top block 6. The flexible groove 18 inside the rotating sleeve 7 no longer limits the outer wall of the flexible block 19. Then, multiple flexible springs 26 synchronously reset and push the flexible block 19, causing the flexible block 19 to drive one side of the snap-fit ​​bracket 20 to move outward. Then, one end of the snap-fit ​​bracket 20 will gradually slide out of the snap-fit ​​groove 21. Then, the snap-fit ​​sleeve 4 is pulled to one side, and the snap-fit ​​rod 3 is pulled to the other side to separate the snap-fit ​​sleeve 4 and the snap-fit ​​rod 3. Then, the other snap-fit ​​sleeves 4 and snap-fit ​​rods 3 are separated according to the above steps. Then, the position of the clamping frame 2 can be moved so that the adjustment hole 22 opened on the clamping frame 2 is concentrically aligned with the corresponding adjustment hole 22 on the lifting frame 1.

[0031] After the clamping frame 2 is properly positioned, first, the locking rod 3 passes through the pre-drilled mounting holes on the clamping frame 2 and the lifting frame 1 from one side. Then, the locking sleeve 4 is fitted onto the outside of the locking rod 3 from the other side. Next, the loosening sleeve 5 is rotated in the opposite direction, causing multiple guide rails 27 on one side to rotate in the opposite direction. The guide rails 27, in conjunction with the guide groove 28, then drive the moving block 10 and the rotating wheel 30 to rotate in the opposite direction. Simultaneously, the loosening sleeve 5 will cause the outer top block 6 to rotate in the opposite direction and reset. The top block 6 then pushes the inclined block 8 to one side, causing the inclined block 8 to slide and reset. The inclined block 8 then drives the rotating sleeve 7 to slide and reset along the guide rail 24, and the rotating sleeve 7 will also drive the inner flexible groove 18 to slide and reset. Because the inner wall of the flexible groove 18... The chamfer design on one side of the flexible block 19's outer wall allows the flexible block 19 to be gradually pressed inward by the inner wall of the flexible groove 18, causing the flexible block 19 to move inward and reset. The flexible block 19 also compresses the flexible spring 26 on one side, causing the flexible block 19 to drive the locking bracket 20 on one side to gradually lock into the locking groove 21. Simultaneously, the rotating sleeve 7 compresses the push spring 9. When the sleeve 5 is released and fully reset, one end of the locking bracket 20 is reinserted into the locking groove 21, forming a locking relationship. At this point, the guide rail 27, through the guide groove 28, drives the moving block 10 and the rotating wheel 30 to rotate and reset between the two locking blocks 17. Then, the moving spring 16 resets and pulls the moving block 10, causing the moving block 10 to drive the guide groove 28 along the guide rail 27. The inner sliding reset occurs, and the moving block 10 drives the one-side rotating wheel 30 to re-engage between the two original locking blocks 17. Then, the configuration plate 14 is rotated forward again, causing the configuration plate 14 to drive the configuration groove 15 and the one-side thrust bearing 29 to rotate forward again. When the configuration groove 15 rotates to the position concentric with the transverse plate 13, the support spring 25 resets and pushes the moving sleeve 11, causing the moving sleeve 11 to drive the one-side interactive plate 12 and the three transverse plates 13 to slide reset. When the support spring 25 is fully reset, the other two transverse plates 13 just move back to the two sides of the configuration plate 14 respectively. Then, the configuration plate 14 is rotated in the reverse direction again, causing the configuration plate 14 to drive the configuration groove 15 and the one-side thrust bearing 29 to rotate in the reverse direction. The configuration slot 15 is rotated and reset to a position that does not correspond to the interactive plate 12 and the horizontal plate 13. Then, the interactive plate 12, in conjunction with the two corresponding horizontal plates 13, limits and supports the movable sleeve 11 to one side of the configuration plate 14, making it impossible for the movable sleeve 11 to slide easily. Then, the inner wall of the movable sleeve 11 will again limit the outer wall of the rotating wheel 30, making it impossible for the rotating wheel 30 and the movable block 10 to slide outward. The rotating wheel 30 and the movable block 10, in conjunction with the locking block 17, are rotated and limited to prevent the loose sleeve 5 from rotating accidentally, thereby achieving a convenient and stable connection. Then, the other snap-fit ​​sleeves 4 and snap-fit ​​rods 3 are snapped together according to the above steps, thereby achieving convenient adjustment of the position of the clamping frame 2, while ensuring the fixed stability of the clamping frame 2.
