Description

Technical Field

[0001] This utility model relates to the field of biodegradable material mixing technology, and more specifically, it relates to a biodegradable material mixing device. Background Technology

[0002] In the context of the rapid development of modern biodegradable materials manufacturing, efficient and reliable mixing devices play a decisive role in the quality and performance of the final product. However, existing biodegradable material mixing devices have significant technical defects that urgently need to be addressed. The primary problem is the overly simple and primitive connection mechanism between the drive unit and the top of the mixing rack, which often uses rigid direct connections or simple key connections. This design exhibits obvious reliability risks when facing complex biodegradable material mixing conditions: when encountering high viscosity areas or material agglomeration during the mixing process, causing the mixing rack to suddenly encounter significant resistance, the connection is prone to breakage, deformation, or loosening due to instantaneous stress concentration. More seriously, this resistance is directly transmitted to the motor system, frequently causing motor failure. Overload operation and abnormal temperature rise can even cause permanent damage such as motor winding burnout, resulting in prolonged equipment downtime and high maintenance costs. Existing overload protection devices typically use a fixed threshold design, which cannot flexibly and accurately adjust the trigger threshold according to the characteristics of different biodegradable materials, the viscosity changes of different batches of materials, or the process requirements of different mixing stages. This unchanging protection mechanism severely limits the adaptability and application range of the equipment. When handling certain special materials, either the threshold setting is too high, which increases the risk of equipment damage, or the threshold setting is too low, which leads to frequent protection triggers and interruptions in the workflow. This seriously affects production efficiency and product quality stability, bringing many adverse effects to enterprises, such as outdated processes and increased costs.

[0003] Secondly, while some manufacturers in the industry have superficially solved the problem of flexibly adjusting overload protection thresholds through innovative designs, these improved designs still have significant structural shortcomings. These adjustment devices often employ simple structures, which are not very stable under complex conditions such as continuous vibration and frequent start-stop cycles in actual industrial environments. Especially in high-speed mixing equipment, these simple structures are prone to slight displacement of the adjustment mechanism itself due to prolonged vibration. As the equipment operates, these slight changes gradually evolve into significant deviations, causing unpredictable changes in the carefully adjusted protection threshold. When the protection threshold deviates, it may not only lead to the failure of the protection function and expose the equipment to the risk of overload damage, but also cause unnecessary frequent shutdowns, affecting production continuity and material mixing uniformity, increasing the difficulty of process parameter control and the uncertainty of the production process, thereby affecting the stability of the entire production system and the consistency of product quality, and bringing significant hidden dangers and potential losses to the company's technological innovation and market competitiveness. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, the present invention provides a biodegradable material mixing device to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a biodegradable material mixing device, comprising a stirring rack, a protective device connected to the top of the stirring rack, the protective device comprising a control sleeve, a connecting sleeve, a connecting rod, a slot, a configuration slot, a configuration plate, a locking block, a configuration block, a linkage sleeve, a control block, a connecting spring, a control slot, and a storage slot, the control sleeve being rotatably mounted on one end of the connecting sleeve, the connecting sleeve being movably mounted on the outside of the connecting rod, the slot being opened on the outside of the connecting rod, the configuration slot being inclinedly opened on the inside of the connecting sleeve, the configuration plate being slidably mounted in the configuration slot, the locking block being connected to the inner wall of the storage slot through the connecting spring, and the locking block being engaged in the slot, the configuration block being fixedly connected to one side of the configuration plate, and the linkage sleeve being movably mounted on the inside of the control sleeve. The control sleeve is movably mounted inside the control sleeve, the control block is fixedly mounted outside the linkage sleeve, the control groove is spirally opened inside the control sleeve, the storage groove is opened in the configuration block, the control block slides in the control groove, and a locking mechanism is provided on the outside of the connecting sleeve. The locking mechanism includes a horizontal plate, a vertical plate, a locking sleeve, a movable groove, a movable plate, a fixed block, a locking spring, and a locking block. The three horizontal plates are fixedly connected to one side of the locking sleeve through the vertical plate. The locking sleeve is slidably mounted on the outside of the connecting sleeve. The movable groove is opened on the movable plate. The movable plate is rotatably mounted on the outside of the connecting sleeve. Multiple fixed blocks are fixedly mounted on the outside of the connecting sleeve. The two ends of the locking spring are respectively connected to two adjacent locking blocks. The locking block is movably mounted on one side of the control sleeve.

[0008] The present invention is further configured such that a mixing tank is provided on the outside of the mixing frame, a hydraulic drive component is provided on one side of the mixing tank, a drive assembly is detachably provided on the top of the hydraulic drive component, and the output end of the drive assembly is detachably connected to the top of the connecting sleeve. The hydraulic drive component provides precise lifting control capability, enabling the mixing frame to smoothly enter or exit the mixing tank, facilitating material unloading operations and cleaning of the mixing tank.

[0009] The present invention is further provided that the top of the mixing tank is detachably provided with a tank cover, which is a split-type structure design. This design facilitates the addition and observation of materials during the mixing process. The split-type tank cover structure allows operators to partially open the tank cover to add auxiliary materials or take samples for testing without stopping the machine, effectively reducing production interruption time and improving work efficiency.

[0010] The present invention is further configured such that a movable spring is connected to one side of the locking sleeve, a thrust bearing is detachably provided on one side of the movable plate, and the other end of the movable spring is connected to the thrust bearing. This elastic connection structure design provides the necessary automatic reset function for the locking system, ensuring that the locking sleeve can automatically and accurately return to its original position after unlocking. The setting of the thrust bearing significantly reduces the frictional resistance between the movable plate and the movable spring when the movable plate rotates, making the locking operation easier and smoother.

[0011] The present invention is further configured such that a plurality of locking rails are connected to one side of the control sleeve, and a locking groove is provided in the locking block. The locking block is slidably installed on the outside of the locking rail through the locking groove. This guide sliding structure ensures that the movement trajectory of the locking block is precise and controllable. The precise cooperation between the locking groove and the locking rail enables the locking block to slide smoothly without jamming or shaking.

[0012] The present invention is further configured such that the fixing block is a cylindrical structure design. This structure design simplifies the manufacturing process while providing excellent support performance. The cylindrical structure allows the fixing block to evenly distribute stress in all directions, avoiding stress concentration points. The outer surface of the cylindrical shape provides an ideal mating surface for the locking wheel, ensuring that the locking wheel can be accurately positioned during the locking process.

[0013] The present invention is further configured such that a locking wheel is rotatably provided on one side of the locking block, and the locking wheel is engaged between the two fixed blocks. This rolling engagement locking design significantly reduces the operating resistance and wear of the locking mechanism. The rotational design of the locking wheel allows the locking block to reduce frictional resistance during movement, achieving easy and smooth locking action. The structure of the locking wheel being engaged between the two fixed blocks forms a stable three-point support, which can effectively resist vibration and impact even during high-speed operation of the equipment, preventing accidental release of the locking state.

[0014] The present invention is further configured such that a mating block is connected to one side of the configuration block, and a mating groove is opened on one side of the linkage sleeve. The mating block slides in the mating groove. This sliding limit design ensures the precise movement and positioning of the protection threshold adjustment system. The precise fit between the mating block and the mating groove ensures that the linkage sleeve can only slide along a predetermined path without rotation or offset, effectively preventing unnecessary movement during the adjustment process and improving the accuracy and stability of threshold adjustment.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a biodegradable material mixing device, which has the following beneficial effects:

[0017] 1. The protective device, through the meticulous design and coordinated operation of the control sleeve, connecting sleeve, connecting rod, slot, configuration slot, configuration plate, locking block, configuration block, linkage sleeve, control block, connecting spring, control slot, and storage slot, innovatively solves a series of problems caused by the simple and primitive connection between the drive component and the stirring frame in existing biodegradable material mixing devices. This device adopts a locking connection principle, achieving torque transmission through the precise cooperation of the locking block and slot. When the stirring frame experiences excessive resistance, the rounded corners of the outer wall of the locking block and the inner wall of the slot allow the locking block to smoothly detach from the slot, press against the connecting spring, and slide into the storage slot, thus protecting the drive assembly and connecting sleeve from idling. This innovative design enables the mixing device to automatically disconnect the power transmission chain when facing high viscosity areas or material agglomeration, effectively avoiding the risk of breakage, deformation, or loosening at the connection due to instantaneous stress concentration. Simultaneously, it prevents… This design prevents overload resistance from being directly transmitted to the motor system, eliminating permanent damage such as motor overload operation, abnormal temperature rise, and even motor winding burnout. In particular, the sliding cooperation between the control slot and the control block, which is spirally opened on the inner side of the control sleeve, combined with the inclined design of the configuration slot and the sliding displacement of the configuration plate, enables the control of the compression degree of the connecting spring. This allows for flexible and precise adjustment of the protection trigger threshold according to the characteristics of different biodegradable materials, the viscosity changes of different batches of materials, or the process requirements of different mixing stages. This adjustable protection mechanism significantly improves the adaptability and application range of the equipment. When processing various biodegradable materials, the optimal protection threshold can be set according to the actual situation, ensuring safe operation of the equipment and guaranteeing production efficiency. It fundamentally solves the problem of equipment use limitation caused by fixed threshold design in existing technologies, bringing significant process advantages and cost benefits to enterprises.

[0018] 2. The locking mechanism consists of a horizontal plate, a vertical plate, a locking sleeve, a movable groove, a movable plate, a fixed block, a locking spring, and a locking block. It innovatively solves the key problem in existing technologies where overload protection devices, after adjustment, are prone to displacement due to equipment operation and other factors. This mechanism forms a double-locking safety system through the precise cooperation of the sliding locking sleeve and the rotating movable plate: firstly, the misalignment and limiting of the movable groove with the horizontal and vertical plates achieves the first mechanical locking; secondly, the locking sleeve limits the outer side of the locking wheel to form a second layer of protection. The locking wheel on one side of the locking block and the locking block's interlocking design, combined with the tension of the locking spring, form a stable and reliable self-locking mechanism. Even under complex operating conditions such as continuous vibration and frequent start-stop cycles during high-speed equipment operation, the locking wheel can still be securely locked. The fixed blocks, with their cylindrical structure and precise engagement with the locking wheels, provide a stable support point for the entire locking system, preventing loosening or shifting between them. The locking blocks, connected to the locking rail via locking grooves, ensure precise guidance of the locking action. This multi-layered locking system fundamentally solves the problem of structural displacement caused by equipment vibration after the protection threshold is adjusted. It ensures that the adjusted protection threshold remains stable over long-term use, effectively avoiding production interruptions and uneven material mixing caused by protection failure or frequent shutdowns. This provides a stable and reliable working guarantee for the biodegradable material mixing device, significantly improving the equipment's adaptability, reliability, and service life, and providing solid technical support for the company's biodegradable material production.

[0028] Please see Figures 1-5A biodegradable material mixing device includes a stirring frame 1, with a protective device connected to the top of the stirring frame 1. The protective device includes a control sleeve 2, a connecting sleeve 3, a connecting rod 4, a slot 5, a configuration slot 6, a configuration plate 7, a locking block 8, a configuration block 9, a linkage sleeve 10, a control block 11, a connecting spring 12, a control slot 13, and a storage slot 14. The control sleeve 2 is rotatably mounted on one end of the connecting sleeve 3, and the connecting sleeve 3 is movably mounted on the outside of the connecting rod 4. The slot 5 is located on the outside of the connecting rod 4, and the configuration slot 6 is inclinedly located on the inside of the connecting sleeve 3. The configuration plate 7 is slidably mounted in the configuration slot 6. The locking block 8 is connected to the inner wall of the storage slot 14 through the connecting spring 12 and is engaged in the slot 5. The configuration block 9 is fixedly connected to one side of the configuration plate 7. The linkage sleeve 10 is movably disposed inside the control sleeve 2, and the control block 11 is fixedly mounted on the inside of the control sleeve 2. The control sleeve 2 is fixedly located on the outside of the linkage sleeve 10. The control groove 13 is spirally opened on the inside of the control sleeve 2. The storage groove 14 is opened in the configuration block 9. The control block 11 is slidably located in the control groove 13. The outer side of the connecting sleeve 3 is provided with a locking mechanism, which includes a horizontal plate 15, a vertical plate 16, a locking sleeve 17, a movable groove 18, a movable plate 19, a fixed block 20, a locking spring 21, and a locking block 22. The three horizontal plates 15 are fixedly connected to one side of the locking sleeve 17 through the vertical plate 16. The locking sleeve 17 is slidably installed on the outside of the connecting sleeve 3. The movable groove 18 is opened on the movable plate 19. The movable plate 19 is rotatably installed on the outside of the connecting sleeve 3. Multiple fixed blocks 20 are fixedly installed on the outside of the connecting sleeve 3. The two ends of the locking spring 21 are respectively connected to two adjacent locking blocks 22. The locking block 22 is movably located on one side of the control sleeve 2.

[0029] A mixing tank 23 is provided on the outside of the mixing rack 1. A hydraulic drive component 24 is provided on one side of the mixing tank 23. A drive assembly 25 is detachably provided on the top of the hydraulic drive component 24. The output end of the drive assembly 25 is detachably connected to the top of the connecting sleeve 3.

[0030] The top of the mixing tank 23 is detachably equipped with a tank cover 26, which is a split-type structure design.

[0031] In this embodiment, when the device is needed, the mixing tank 23 is first moved directly below the mixing frame 1 and concentric with it. Then, raw materials are added to the mixing tank 23. Next, the hydraulic drive unit 24 is turned on, causing the drive assembly 25 and the mixing frame 1 to descend, allowing the mixing frame 1 to enter the mixing tank 23. Then, the hydraulic drive unit 24 is turned off. The tank cover 26 is then detachably installed above the mixing tank 23. The drive assembly 25 is then turned on, causing the connecting sleeve 3 to rotate. The connecting sleeve 3 then rotates the inner configuration groove 6, causing the configuration plate 7 to rotate the configuration block 9. The configuration block 9, through the inner receiving groove 14, drives the connecting spring 12 and the locking block 8 to rotate. The locking block 8, through its engagement with the locking groove 5, drives the mixing frame 1 to rotate, thus achieving the mixing of the raw materials. During the mixing process, when the mixing frame 1 experiences significant resistance, the connecting rod 4 and the slot 5 stop rotating. The inner wall of the slot 5 presses against the outer wall of the block 8. Due to the rounded corner design of the outer wall of the block 8 and the inner wall of the slot 5, the block 8 gradually disengages from the slot 5. Then, the block 8 presses against the connecting spring 12 on one side and gradually slides into the receiving slot 14, causing the drive assembly 25 to drive the connecting sleeve 3 to idle, thus achieving overload protection. After mixing is complete, the tank cover 26 is removed, and the hydraulic drive component 24 is reversed to raise the mixing frame 1 again. Then, the mixing tank 23 is moved, and the material can be discharged by tilting the mixing tank 23. During this process, another empty mixing tank 23 can be moved back under the mixing frame 1 to ensure production continuity and facilitate the cleaning of the inner wall of the used mixing tank 23.

[0032] Please see Figures 3-5 As a further implementation of the overall equipment: a movable spring 27 is connected to one side of the locking sleeve 17, and a thrust bearing 28 is detachably provided on one side of the movable plate 19. The other end of the movable spring 27 is connected to the thrust bearing 28.

[0033] Multiple locking rails 29 are connected to one side of the control sleeve 2, and a locking groove 30 is opened in the locking block 22. The locking block 22 is slidably installed on the outside of the locking rail 29 through the locking groove 30.

[0034] The fixing block 20 is designed as a column structure.

[0035] A locking wheel 31 is provided on one side of the locking block 22, and the locking wheel 31 is engaged between the two fixing blocks 20.

[0036] A mating block 32 is connected to one side of the configuration block 9, and a mating groove 33 is opened on one side of the linkage sleeve 10. The mating block 32 slides in the mating groove 33.

[0037] More specifically, when the protection threshold needs to be adjusted, firstly, rotate the movable plate 19, causing the thrust bearing 28 and the movable groove 18 to rotate, and rotate the movable groove 18 to the position corresponding to the horizontal plate 15. Then, push the locking sleeve 17, causing the locking sleeve 17 to drive the vertical plate 16 and the horizontal plate 15 to gradually slide through the movable groove 18. The locking sleeve 17 will cooperate with the thrust bearing 28 to compress the movable spring 27. When the movable spring 27 is compressed to its limit, the horizontal plate 15 closest to the locking sleeve 17 will just slide through the movable groove 18 and move to the other side of the movable plate 19. Then, rotate the movable plate 19 in the opposite direction, causing the movable groove 18 and the thrust bearing 28 to rotate in the opposite direction, and causing the movable groove 18 to rotate and reset. When the lock sleeve 17 is positioned to a position not corresponding to the locking plate, the longitudinal plate 16, in conjunction with the transverse plate 15 closest to the locking sleeve 17, limits the locking sleeve 17 to one side of the movable plate 19, so that the locking sleeve 17 no longer limits the outer side of the locking wheel 31. Then, the control sleeve 2 rotates forward. The control sleeve 2, through the locking rail 29 on one side and the locking groove 30, drives the locking block 22 to rotate forward. Then, the locking block 22 will drive the locking wheel 31 to roll out between the two fixed blocks 20, and the locking wheel 31 will drive the locking block 22 to slide outward along the locking rail 29 and the locking groove 30, so that the locking block 22 drives the locking spring 21 to stretch outward. At the same time, the control sleeve 2 will drive the inner spirally opened control groove 13 to rotate forward, so that the control block 11 slides in the control groove 13. Due to the linkage sleeve When the linkage sleeve 10 is stopped by the limiting action of the mating block 32 and the mating groove 33, it will not rotate. Then, the linkage block will drive the linkage sleeve 10 to slide, causing the linkage sleeve 10 to push the side configuration block 9 to slide. Then, the configuration block 9 will drive the side configuration plate 7 to slide along the configuration groove 6, and the configuration block 9 will drive the other side locking block 8 to slide upward along the locking groove 5. Since the configuration groove 6 is inclined, the configuration plate 7 will drive the configuration block 9 to converge inward, and the configuration block 9 will drive the mating block 32 on one side to slide inward along the mating groove 33. Then, the distance between the inner wall of the receiving groove 14 and the side of the locking block 8 will shorten, causing the connecting spring 12 to be compressed to a certain extent, increasing the thrust exerted by the connecting spring 12 on the locking block 8, thus requiring the side wall of the locking block 8 to withstand greater force. The block 8 can disengage from the slot 5. When the side wall of the block 8 needs to be adjusted to withstand less force so that it can disengage from the slot 5, simply rotate the control sleeve 2 in the reverse direction as described above. After the protection threshold is adjusted appropriately, stop rotating the control sleeve 2 and allow the locking rail 29 and locking groove 30 to cooperate in rotating the locking block 22 between the two corresponding fixed blocks 20. Then, the locking spring 21 pulls the locking block 22 to slide inward along the locking rail 29 and locking groove 30. The locking block 22 will then drive one side locking wheel 31 to engage between the two corresponding fixed blocks 20. Then, rotate the movable plate 19 forward again, causing the movable plate 19 to drive the thrust bearing 28 and the movable groove 18 to rotate forward again. When the movable groove 18 rotates to the position corresponding to the horizontal plate 15 again...The movable spring 27 pushes the locking sleeve 17 to slide and reset. Then, the locking sleeve 17 drives the three horizontal plates 15 to slide and reset via the longitudinal plate 16. When the movable spring 27 is fully reset, the other two horizontal plates 15 are positioned on either side of the movable plate 19. The movable plate 19 is then rotated again, causing the thrust bearing 28 and the movable groove 18 to rotate forward. The movable groove 18 then rotates to a position that does not correspond to the horizontal plates 15 and the longitudinal plate 16. The longitudinal plate 16 and the two horizontal plates 15 then cooperate to support and limit the locking sleeve to one side of the movable plate 19, preventing the locking sleeve 17 from sliding easily. The inner wall of the locking sleeve 17 then limits the outer side of the locking wheel 31, preventing the locking wheel 31 and the locking block 22 from moving outward. This achieves rotational limitation of the control sleeve 2, ensuring the structural stability after the protection threshold adjustment and ensuring stable use.

[0038] In summary, when using or operating the entire equipment: First, move the mixing tank 23 directly below and concentrically with the mixing frame 1. Then, add raw materials to the mixing tank 23. Next, open the hydraulic drive unit 24, causing it to lower the drive assembly 25 and the mixing frame 1, allowing the mixing frame 1 to enter the mixing tank 23. Then, close the hydraulic drive unit 24. Next, detachably install the tank cover 26 above the mixing tank 23. Then, open the drive assembly 25, causing it to rotate the connecting sleeve 3. The connecting sleeve 3 then rotates the inner configuration slot 6, causing the configuration plate 7 to rotate the configuration block 9. The configuration block 9, through the inner receiving slot 14, rotates the connecting spring 12 and the locking block 8. The locking block 8, through its engagement with the locking slot 5, rotates the mixing frame 1, ensuring the mixing frame 1 rotates. During the mixing process, when the mixing frame 1 experiences significant resistance, the connecting rod 4 and the slot 5 stop rotating. The inner wall of the slot 5 presses against the outer wall of the block 8. Due to the rounded corner design of the outer wall of the block 8 and the inner wall of the slot 5, the block 8 gradually disengages from the slot 5. Then, the block 8 presses against the connecting spring 12 on one side and gradually slides into the receiving slot 14, causing the drive assembly 25 to drive the connecting sleeve 3 to idle, thus achieving overload protection. After mixing is complete, the tank cover 26 is removed, and the hydraulic drive component 24 is reversed to raise the mixing frame 1 again. Then, the mixing tank 23 is moved, and the material can be discharged by tilting the mixing tank 23. During this process, another empty mixing tank 23 can be moved back to below the mixing frame 1 to ensure production continuity and facilitate the cleaning of the inner wall of the used mixing tank 23.

[0039] When the protection threshold needs to be adjusted, first rotate the movable plate 19, causing the thrust bearing 28 and the movable groove 18 to rotate, and the movable groove 18 to rotate to the position corresponding to the horizontal plate 15. Then push the locking sleeve 17, causing the locking sleeve 17 to drive the vertical plate 16 and the horizontal plate 15 to gradually slide through the movable groove 18. The locking sleeve 17 will cooperate with the thrust bearing 28 to compress the movable spring 27. When the movable spring 27 is compressed to its limit, the horizontal plate 15 closest to the locking sleeve 17 will just slide through the movable groove 18 and move to the other side of the movable plate 19. Then rotate the movable plate 19 in the opposite direction, causing the movable plate 19 to drive the movable groove 18 and the thrust bearing 28 to rotate in the opposite direction, and the movable groove 18 to rotate back to a position where it is not stuck. At the corresponding position of the plate, the longitudinal plate 16, together with the transverse plate 15 closest to the locking sleeve 17, limits the locking sleeve 17 to one side of the movable plate 19, so that the locking sleeve 17 no longer limits the outer side of the locking wheel 31. Then, the control sleeve 2 rotates forward. The control sleeve 2 drives the locking block 22 to rotate forward through the locking rail 29 and the locking groove 30. Then, the locking block 22 will drive the locking wheel 31 to roll out between the two fixed blocks 20, and the locking wheel 31 will drive the locking block 22 to slide outward along the locking rail 29 and the locking groove 30, so that the locking block 22 drives the locking spring 21 to stretch outward. At the same time, the control sleeve 2 will drive the inner spirally opened control groove 13 to rotate forward, so that the control block 11 slides in the control groove 13. Due to the linkage sleeve 10 The limiting effect of the mating block 32 and the mating groove 33 prevents the linkage sleeve 10 from rotating. The linkage block then causes the linkage sleeve 10 to slide, pushing one side of the configuration block 9 to slide. The configuration block 9 then causes one side of the configuration plate 7 to slide along the configuration groove 6, and the configuration block 9 also causes the other side of the locking block 8 to slide upwards along the locking groove 5. Since the configuration groove 6 is angled, the configuration plate 7 causes the configuration block 9 to converge inwards, and the configuration block 9 causes one side of the mating block 32 to slide inwards along the mating groove 33. This shortens the distance between the inner wall of the receiving groove 14 and one side of the locking block 8, causing the connecting spring 12 to be compressed to a certain extent. This increases the thrust exerted by the connecting spring 12 on the locking block 8, thus requiring the side wall of the locking block 8 to withstand greater force. To disengage from slot 5, when the side wall of the locking block 8 needs to be adjusted to withstand less force to disengage from slot 5, simply reverse the control sleeve 2 as described above. Once the protection threshold is adjusted appropriately, stop rotating the control sleeve 2, and allow the locking rail 29 and locking groove 30 to engage and rotate the locking block 22 between the corresponding two fixed blocks 20. Then, the locking spring 21 pulls the locking block 22 to slide inward along the locking rail 29 and locking groove 30. The locking block 22 will then drive one side locking wheel 31 to engage between the corresponding two fixed blocks 20. Then, rotate the movable plate 19 forward again, causing the movable plate 19 to once again drive the thrust bearing 28 and the movable groove 18 to rotate forward. When the movable groove 18 rotates again to the position corresponding to the horizontal plate 15,The movable spring 27 pushes the locking sleeve 17 to slide and reset. Then, the locking sleeve 17 drives the three horizontal plates 15 to slide and reset via the longitudinal plate 16. When the movable spring 27 is fully reset, the other two horizontal plates 15 are positioned on either side of the movable plate 19. The movable plate 19 is then rotated again, causing the thrust bearing 28 and the movable groove 18 to rotate forward. The movable groove 18 then rotates to a position that does not correspond to the horizontal plates 15 and the longitudinal plate 16. The longitudinal plate 16 and the two horizontal plates 15 then cooperate to support and limit the locking sleeve to one side of the movable plate 19, preventing the locking sleeve 17 from sliding easily. The inner wall of the locking sleeve 17 then limits the outer side of the locking wheel 31, preventing the locking wheel 31 and the locking block 22 from moving outward. This achieves rotational limitation of the control sleeve 2, ensuring the structural stability after the protection threshold adjustment and ensuring stable use.
