Description

Technical Field

[0001] This utility model relates to the field of raw material addition technology for heavy metal ion scavenging agents, and more specifically, it relates to a raw material addition device for the production of heavy metal ion scavenging agents. Background Technology

[0002] In the existing field of raw material addition devices for the production of heavy metal ion scavengers, the following technical bottlenecks urgently need to be addressed:

[0003] Firstly, in terms of raw material ratio control, existing technologies generally lack precise weight ratio feeding functions. Traditional addition devices mostly adopt timed feeding or volumetric feeding methods. This method cannot monitor and control the actual feeding weight of raw materials in real time, resulting in large deviations in the formula ratio of different batches of products. This defect is more obvious when processing solid raw materials with uneven density. Since heavy metal ion capture agents have extremely high requirements for the precision of raw material ratio, this extensive feeding method will directly affect the performance indicators of the final product, leading to problems such as unstable capture efficiency and fluctuations in heavy metal removal rate, which will seriously have an adverse impact on product quality control.

[0004] Secondly, some improved equipment attempts to achieve proportion control through mechanical weighing structures. A typical design involves setting a spring-supported discharge bin below the feed hopper. When the weight of the material in the discharge bin exceeds the preset spring force threshold, the discharge bin will rotate and open to achieve automatic discharge. However, this design has obvious limitations: on the one hand, the spring's thrust threshold is usually fixed and cannot be flexibly adjusted according to different formulation requirements. In actual production, different types of capture agents may require different discharge thresholds, and the fixed support force setting cannot cover a wide range of adjustments. This rigid structure cannot meet the needs of modern production for diversified formulations and restricts the development process of new products.

[0005] Furthermore, while some advanced equipment has achieved adjustable threshold functionality, it suffers from serious structural instability. These devices typically employ simple adjustment mechanisms to alter spring preload, but such structures are highly susceptible to loosening and displacement under continuous material feeding vibration and impact. Specifically, during the feeding process, material impact causes the adjustment components to gradually rotate and loosen, potentially leading to deviations in the preset feeding threshold after several hours of continuous operation. More seriously, this loosening is often difficult to detect in a timely manner, resulting in a large number of defective products and increased maintenance costs. This lack of stability makes it difficult for adjustable equipment to fully realize its technological advantages in actual production. Utility Model Content

[0009] To achieve the above objectives, this utility model provides the following technical solution: a raw material addition device for the production of heavy metal ion scavenging agents, comprising a base, a feeding device mounted on the base, and an adjustment device provided on the base. The adjustment device includes a fixed sleeve, a rotating sleeve, a screw sleeve, a linkage sleeve, a mating groove, a push spring, a push plate, a mating plate, and a mating block.

The movable plate is rotatably installed outside the fixed sleeve. Multiple positioning blocks are fixedly installed outside the fixed sleeve.

[0010] The present invention is further configured such that the feeding device includes a feeding hopper, a discharging bin, a guide platform, a rotating shaft, a connecting frame, a bracket, a connecting spring, a connecting sleeve, a connecting rod, and a connecting plate.

The connecting sleeve and the connecting rod are slidably connected. One end of the connecting rod is rotatably connected to the discharging bin via the connecting frame. The connecting plate is fixedly installed on the outside of the connecting rod and one end of the fixed sleeve.

[0011] The present invention is further configured such that a clamping wheel is rotatably provided on one side of the clamping block, the clamping wheel is engaged between two positioning blocks, multiple clamping rails are connected to one side of the rotating sleeve, a clamping groove is provided on one side of the clamping block, the clamping rails are adapted to the clamping grooves, and the clamping wheel is engaged and locked with the positioning block, and the clamping rails and clamping grooves are slidably guided, so as to achieve precise positioning and reliable locking when the rotating sleeve rotates, effectively preventing the adjustment mechanism from loosening due to equipment vibration.

[0012] The present invention is further configured such that an arc-shaped rod is connected to one side of the movable block, and an arc-shaped hole is opened in the fixed block. One end of the arc-shaped rod slides into the arc-shaped hole. Through the sliding cooperation of the arc-shaped rod in the arc-shaped hole, a precise rotation trajectory is provided for the movable plate and the arc-shaped spring, ensuring the motion accuracy and stability of the locking mechanism when it is in action, and avoiding the phenomenon of the mechanism getting stuck or misaligned.

[0013] The present invention is further configured such that a plurality of anti-slip strips are fixedly provided on one side of the push plate, the anti-slip strips are made of rubber material, and a plug rod is fixedly connected to the other side of the push plate. A slot is provided in the mating block, one end of the plug rod slides into the slot, and the push spring is movably sleeved on the outside of the plug rod. The friction coefficient between the push plate and the connecting rod is enhanced by the rubber anti-slip strips, and the cooperation between the plug rod and the slot provides a precise guiding effect for the push spring, which ensures both adjustment sensitivity and operational reliability.

[0014] The present invention is further configured such that a push spring is connected to one side of the clamping sleeve, the push spring is movably sleeved on the outside of the push rod, and the other end of the push spring is in contact with the movable plate.

The outer wall of the linkage sleeve is fixedly connected to the inner wall of the threaded sleeve through the movable block. By guiding the movable block in the movable groove, the reliable connection between the linkage sleeve and the threaded sleeve is ensured, and the rotational freedom of the linkage sleeve is restricted, thereby ensuring the motion accuracy and stability during thread transmission.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a raw material addition device for the production of heavy metal ion scavenging agents, which has the following beneficial effects:

[0019] 1. The feeding device uses a rotating shaft connection structure between the feeding hopper and the discharge bin, combined with the inclined design of the guide table and the elastic support of the connecting spring, to achieve automatic control of feeding based on a weight threshold. When the weight of the material in the discharge bin exceeds the set value, the connecting mechanism automatically triggers the discharge bin to tilt to complete precise feeding. This structure overcomes the proportioning error problem existing in traditional feeding methods and can maintain stable proportioning accuracy when processing raw materials of different densities. The inclined design of the guide table ensures that the material is concentrated and piled up.

[0020] 2. The adjustment device adopts the synergistic effect of threaded transmission mechanism and inclined mating groove to achieve stepless adjustment of the support force threshold. The axial movement is driven by the rotating mechanism, which drives the linkage component to push the mating block to slide at a specific angle, thereby adjusting the distance between the two connecting plates. This design solves the problem of limited adjustment range of traditional equipment and can accurately adapt to the production needs of different types of capture agents. The elastic element and guide structure ensure the stability and repeatability of the adjustment process, effectively improving the flexibility of equipment use and ensuring diversified production.

[0021] 3. The locking mechanism innovatively adopts a locking mechanism combined with a double limit structure, which effectively solves the stability problem of the equipment under vibration conditions. Through the precision guide mechanism, the moving parts form a mechanical interlock, which, together with the elastic clamping force, can resist strong material feeding impact. The sliding fit structure ensures motion accuracy and prevents parameter drift caused by loosening of the adjustment mechanism. This structure can still maintain stable operation when processing large particle raw materials, so that the equipment can maintain the accuracy of preset parameters during continuous operation and ensure long-term stable use of the equipment.

[0031] Please see Figures 1-5A raw material addition device for the production of heavy metal ion scavenging agents includes a base 1, a feeding device mounted on the base 1, and an adjustment device on the base 1. The adjustment device includes a fixed sleeve 2, a rotating sleeve 3, a screw sleeve 4, a linkage sleeve 5, a mating groove 6, a push spring 7, a push plate 8, a mating plate 9, and a mating block 10. The rotating sleeve 3 is rotatably mounted on the outside of the fixed sleeve 2. The outer wall of the screw sleeve 4 is movably connected to the inner wall of the rotating sleeve 3 via threads. The linkage sleeve 5 is movably disposed in the fixed sleeve 2. The mating groove 6 is inclinedly opened in the fixed sleeve 2. One side of the push plate 8 is connected to the mating block 10 via the push spring 7. The mating plate 9 is slidably disposed in the mating groove 6. The mating block 10 is fixedly connected to one side of the mating plate 9. A locking mechanism is provided on the outside of the fixed sleeve 2, which includes a clamping sleeve 11, a fixed block 12, a movable hole 13, and a movable groove 14. The system includes a movable block 15, a clamping spring 16, a clamping block 17, a push rod 18, a push plate 19, an arc spring 80, a movable plate 20, and positioning blocks 21. The arc spring 80 is connected to the movable block 15 and the fixed block 12 at both ends. The clamping sleeve 11 is located on the outside of the fixed sleeve 2. The fixed block 12 is fixedly installed on the outside of the fixed sleeve 2. The movable hole 13 is opened at one end of the movable groove 14. The movable groove 14 is opened on the movable plate 20. The movable block 15 is fixedly installed on one side of the movable plate 20. The clamping spring 16 is connected to two adjacent clamping blocks 17 at both ends. The clamping block 17 is movably located on one side of the rotating sleeve 3. The push rod 18 is fixedly connected to one side of the clamping sleeve 11. Two push plates 19 are fixedly installed on the push rod 18. The movable plate 20 is rotatably installed on the outside of the fixed sleeve 2. Multiple positioning blocks 21 are fixedly installed on the outside of the fixed sleeve 2.

[0032] The feeding device includes a feeding hopper 22, a discharging bin 23, a guide table 24, a rotating shaft 25, a connecting frame 26, a bracket 27, a connecting spring 28, a connecting sleeve 29, a connecting rod 30, and a connecting plate 31. The feeding hopper 22 is detachably installed inside the bracket 27. The discharging bin 23 is installed at the bottom of the feeding hopper 22 via the rotating shaft 25. The guide table 24 is located inside the feeding hopper 22. The connecting frame 26 is installed on the base 1 and below the discharging bin 23, respectively. The bracket 27 is detachably installed on the base 1. The two ends of the connecting spring 28 are connected to the connecting plate 31, respectively. One end of the connecting sleeve 29 is rotatably connected to the base 1 via the connecting frame 26. The connecting sleeve 29 and the connecting rod 30 are slidably connected. One end of the connecting rod 30 is rotatably connected to the discharging bin 23 via the connecting frame 26. The connecting plate 31 is fixedly installed on the outside of the connecting rod 30 and one end of the fixed sleeve 27, respectively.

[0033] In this embodiment, when the device is to be used, the raw materials to be added are first added to the feed hopper 22. Due to the inclined structure of the guide table 24, the raw materials will gradually accumulate on one side inside the feed hopper 22. When the weight exceeds the support force threshold, the connecting rod 30 slides inward to the connecting sleeve 29, and the distance between the two connecting plates 31 is shortened, so that the connecting plate 31 squeezes the connecting spring 28, causing the discharge bin 23 to rotate around the rotating shaft 25 as the center, causing the discharge bin 23 to tilt, and at the same time stopping the addition of raw materials into the feed hopper 22. Then the raw materials can be added to the processing equipment.

[0034] Please see Figures 3-5 As a further implementation of the overall equipment: a clamping wheel 32 is rotatably provided on one side of the clamping block 17, and the clamping wheel 32 is inserted between two positioning blocks 21. Multiple clamping rails 33 are connected to one side of the rotating sleeve 3, and a clamping groove 34 is opened on one side of the clamping block 17. The clamping rails 33 and the clamping grooves 34 are adapted to each other.

[0035] An arc-shaped rod 35 is connected to one side of the movable block 15, and an arc-shaped hole 36 is opened in the fixed block 12. One end of the arc-shaped rod 35 slides into the arc-shaped hole 36.

[0036] Multiple anti-slip strips 37 are fixedly provided on one side of the push plate 8. The anti-slip strips 37 are made of rubber. A plug rod 38 is fixedly connected to the other side of the push plate 8. A slot 39 is provided in the mating block 10. One end of the plug rod 38 slides into the slot 39, and the push spring 7 is movably sleeved on the outside of the plug rod 38.

[0037] A push spring 40 is connected to one side of the clamping sleeve 11. The push spring 40 is movably sleeved on the outside of the push rod 18. The other end of the push spring 40 is in contact with the movable plate 20. A guide block 41 is fixedly provided on the inner side of the clamping sleeve 11. A guide groove 42 is opened on the outer side of the fixed sleeve 2. The guide block 41 is slidably disposed in the guide groove 42.

[0038] A linkage groove 43 is provided on one side of the linkage sleeve 5, and a linkage plate 44 is fixedly provided on one side of the mating block 10. The linkage plate 44 is slidably disposed in the linkage groove 43.

[0039] The fixed sleeve 2 has a movable groove 45, and a movable block 46 is slidably provided in the movable groove 45. The outer wall of the linkage sleeve 5 is fixedly connected to the inner wall of the screw sleeve 4 through the movable block 46.

[0040] More specifically, when the preload of the connecting spring 28 needs to be adjusted, firstly, the movable plate 20 is rotated forward, causing the movable plate 20 to drive the movable block 15 on one side to rotate forward. Then, the movable block 15 will drive the arc-shaped rod 35 to rotate along the arc-shaped hole 36 opened in the fixed block 12, and the movable block 15 and the fixed block 12 will cooperate to compress the arc-shaped spring 80. The movable plate 20 will also drive the movable groove 14 and the movable hole 13 to rotate forward. When the movable hole 13 rotates to a position concentric with the push plate 19, it pushes the clamping sleeve 11. The clamping sleeve 11 drives the guide block 41 on the inner side to slide along the guide groove 42, and the clamping sleeve 11 will drive the push rod 18 and the push plate 19 to gradually slide into the movable hole 13. At the same time, the clamping sleeve 11 will cooperate with the movable plate 20 to compress the arc-shaped spring 80. When the push spring 40 is compressed to its limit, a push plate 19 near the clamping sleeve 11 passes through the movable hole 13 and moves to the other side of the movable plate 20. Then the movable plate 20 is released, and the arc spring 80 pushes the movable block 15 to rotate in the opposite direction. The movable block 15 then drives the movable plate 20 to rotate in the opposite direction, causing the arc rod 35 on one side to rotate in the opposite direction along the arc hole 36. This causes the push rod 18 to enter the movable groove 14. The push rod 18, together with the push plate 19 near the clamping sleeve 11, limits the clamping sleeve 11 to one side of the movable plate 20, so that the clamping sleeve 11 no longer limits the outer side of the clamping wheel 32. Then the rotating sleeve 3 rotates in the forward direction, and the rotating sleeve 3 drives the clamping rail 33 on one side. The locking rail 33 rotates, and then the locking block 17 rotates forward through the locking groove 34. The locking block 17 then moves the locking wheel 32 out from between the two positioning blocks 21, and the locking wheel 32 moves the locking block 17 outward along the locking rail 33 and locking groove 34. This causes the locking block 17 to stretch the locking spring 16 outward. Simultaneously, because the inner wall of the rotating sleeve 3 is connected to the outer wall of the threaded sleeve 4 via threads, and because the moving block 46 and moving groove 45 limit the movement of the threaded sleeve 4, the threaded sleeve 4 will not rotate. The threaded sleeve 4 then moves the moving block 46 along the moving groove 45, causing the moving block 46 to move the linkage sleeve 5. The linkage sleeve 5, through the linkage groove 43 and the linkage plate 44, moves the mating block 10 to one side. The mating block 10, through the engagement of the insert rod 38 and the slot 39, drives the push spring 7 and the push plate 8 to move. Simultaneously, the mating block 10 causes the mating plate 9 on one side to slide along the mating groove 6. Due to the inclined structure of the mating groove 6, the mating plate 9 then causes the mating block 10 to spread outwards, causing the mating block 10 to drive the linkage plate 44 on one side to slide outwards along the linkage groove 43. The mating block 10 also causes the slot 39 to move outwards, causing a portion of the insert rod 38 to gradually move out of the slot 39. The push spring 7 gradually returns to its original position, increasing the distance between the push plate 8 and the mating block 10. When the push spring 7 is fully returned to its original position, the mating block 10, through the push spring 7, drives the push plate 8 to move outwards, so that the inner wall of the push plate 8 no longer contacts the outer wall of the connecting rod 30.Then, push the fixed sleeve 2 forward, causing the fixed sleeve 2 to move the connecting plate 31 at one end along the connecting sleeve 29, shortening the distance between the two connecting plates 31. This causes the connecting plate 31 to compress the connecting spring 28 to a certain extent, increasing the thrust of the connecting spring 28 on the connecting plate 31. This means that tilting can only occur when there is more weight above the discharge bin 23. When tilting for material discharge is only needed when there is less weight above the discharge bin 23, push the fixed sleeve 2 in the reverse direction. After adjusting to the appropriate threshold, stop sliding the fixed sleeve 2, and then rotate the rotating sleeve 3 in the reverse direction. This causes the screw sleeve 4 to drive the linkage sleeve 5 to slide in the reverse direction via the moving block 46. Then, the linkage sleeve 5 pushes the mating block 10 to slide in the reverse direction, causing the mating block 10 to... The insertion rod 38 and slot 39 work together to drive the push plate 8 and push spring 7 to slide in opposite directions. Then, the mating block 10 drives the mating plate 9 to slide in opposite directions along the mating groove 6. The mating plate 9 then drives the mating block 10 to converge and reset inward. The mating block 10 then drives the push plate 8 to converge and reset inward through the push spring 7. At the same time, the mating block 10 drives the linkage plate 44 to slide and reset inward along the linkage groove 43. Then, the inner wall of the push plate 8 contacts the outer wall of the connecting sleeve 29. Then, the mating block 10 continues to move, and the distance between the mating block 10 and the push plate 8 decreases, so that the mating plate 9 and the push plate 8 press against the push spring 7. At the same time, one end of the insertion rod 38 gradually penetrates into the slot 39. After the push spring 7 is pressed, the push plate 8 presses against the outer wall of the connecting sleeve 29 through the anti-slip sleeve set on the inner side. The clamping mechanism compresses the clamping block 17, causing it to rotate in the opposite direction between the two original positioning blocks 21. Then, the clamping spring 16 resets and pulls the clamping block 17 inwards, causing it to engage the clamping wheel 32 between the two original positioning blocks 21. Next, the movable plate 20 rotates forward again, causing the movable plate 20 to rotate forward again along the movable hole 13 and movable groove 14. The movable block 15 then rotates the arc-shaped rod 35 forward along the arc-shaped hole 36. The movable block 15 and the fixed block 12 then work together to press against the arc-shaped spring 80. When the movable hole 13 rotates to a position concentric with the push plate 19, the push spring 40 resets and pushes the clamping sleeve 11, causing the clamping sleeve 11 to engage the inner guide block 4. 1. The sleeve 11 slides and resets along the guide groove 42, and the locking sleeve 11 drives the two push plates 19 to slide and reset via the push rod 18. Then, the push plate 19 at the top of the push rod 18 moves back to the original side of the movable plate 20. Then, the movable plate 20 is released again, and the arc spring 80 pushes the movable block 15 to rotate and reset. Then, the movable block 15 drives the arc rod 35 to rotate and reset along the arc hole 36. The movable block 15 drives the movable hole 13 and the movable groove 14 to rotate and reset to a position that does not correspond to the push rod 18 and the push plate 19 via the movable plate 20. Then, the push rod 18 and the push plate 19 at its end form a limiting support for the locking sleeve 11. Together with the guide block 41 and the guide groove 42 limiting the rotation of the locking sleeve 11, the locking sleeve 11 cannot slide.Then, the inner wall of the clamping sleeve 11 limits the outer side of the clamping wheel 32, preventing the clamping block 17 and the clamping wheel 32 from moving outward. This achieves rotational limitation of the rotating sleeve 3, ensuring structural stability and the stable operation of the equipment.

[0041] In summary, when using or operating the equipment: First, add the raw materials to be added into the feed hopper 22. Due to the inclined structure of the guide table 24, the raw materials will gradually accumulate on one side inside the feed hopper 22. When the weight exceeds the support force threshold, the connecting rod 30 slides inward into the connecting sleeve 29, and the distance between the two connecting plates 31 shortens, causing the connecting plate 31 to squeeze the connecting spring 28, causing the discharge bin 23 to rotate around the rotating shaft 25, causing the discharge bin 23 to tilt, and at the same time stopping the addition of raw materials into the feed hopper 22. Then, the raw materials can be added to the processing equipment.

[0042] When the preload of the connecting spring 28 needs to be adjusted, first rotate the movable plate 20 clockwise, causing the movable plate 20 to drive the movable block 15 on one side to rotate clockwise. Then, the movable block 15 will drive the arc-shaped rod 35 to rotate along the arc-shaped hole 36 in the fixed block 12, and the movable block 15 and the fixed block 12 will cooperate to compress the arc-shaped spring 80. The movable plate 20 will also drive the movable groove 14 and the movable hole 13 to rotate clockwise. When the movable hole 13 rotates to a position concentric with the push plate 19, it will push the clamping sleeve 11. The clamping sleeve 11 will drive the guide block 41 on the inner side to slide along the guide groove 42, and the clamping sleeve 11 will drive the push rod 18 and the push plate 19 to gradually slide into the movable hole 13. At the same time, the clamping sleeve 11 and the movable plate 20 will cooperate to compress the push spring 40. When the push spring 40 is compressed to its limit, a push plate 19 near the clamping sleeve 11 passes through the movable hole 13 and moves to the other side of the movable plate 20. Then the movable plate 20 is released, and the arc spring 80 pushes the movable block 15 to rotate in the opposite direction. The movable block 15 then drives the movable plate 20 to rotate in the opposite direction, causing the arc rod 35 on one side to rotate in the opposite direction along the arc hole 36. This causes the push rod 18 to enter the movable groove 14. The push rod 18, together with the push plate 19 near the clamping sleeve 11, limits the clamping sleeve 11 to one side of the movable plate 20, so that the clamping sleeve 11 no longer limits the outer side of the clamping wheel 32. Then the rotating sleeve 3 rotates in the forward direction, and the rotating sleeve 3 drives the clamping rail 33 on one side to rotate. The clamping rail 33 drives the clamping block 17 to rotate forward through the clamping groove 34. Then, the clamping block 17 drives the clamping wheel 32 to move out from between the two positioning blocks 21. The clamping wheel 32 drives the clamping block 17 to slide outward along the clamping rail 33 and the clamping groove 34, causing the clamping block 17 to stretch the clamping spring 16 outward. At the same time, because the inner wall of the rotating sleeve 3 is movably connected to the outer wall of the threaded sleeve 4 through the thread, and the moving block 46 and the moving groove 45 limit the threaded sleeve 4, the threaded sleeve 4 will not rotate. Then, the threaded sleeve 4 drives the moving block 46 to slide along the moving groove 45, and the moving block 46 drives the linkage sleeve 5 to slide. The linkage sleeve 5 drives the mating block 10 to slide to one side through the linkage groove 43 and the linkage plate 44. Then, the mating block 10 will... The engagement of the insertion rod 38 and the slot 39 causes the push spring 7 and the push plate 8 to move. Simultaneously, the mating block 10 causes the mating plate 9 on one side to slide along the mating groove 6. Due to the inclined structure design of the mating groove 6, the mating plate 9 then causes the mating block 10 to spread outward, causing the mating block 10 to cause the linkage plate 44 on one side to slide outward along the linkage groove 43. The mating block 10 also causes the slot 39 to move outward, causing a portion of the insertion rod 38 to gradually move out of the slot 39. The push spring 7 gradually returns to its original position, increasing the distance between the push plate 8 and the mating block 10. When the push spring 7 has fully returned to its original position, the mating block 10, through the push spring 7, causes the push plate 8 to move outward, so that the inner wall of the push plate 8 no longer contacts the outer wall of the connecting rod 30, and then pushes the fixing sleeve 2 forward.The fixed sleeve 2 causes the connecting plate 31 at one end to move along the connecting sleeve 29, shortening the distance between the two connecting plates 31. This causes the connecting plate 31 to compress the connecting spring 28 to a certain extent, increasing the pushing force of the connecting spring 28 on the connecting plate 31. This means that tilting only occurs when there is more weight above the discharge bin 23. When less weight is needed above the discharge bin 23 for tilting and material discharge, the fixed sleeve 2 is pushed in the reverse direction. Once the appropriate threshold is reached, the sliding of the fixed sleeve 2 stops, and then the rotating sleeve 3 is rotated in the reverse direction. This causes the screw sleeve 4 to drive the linkage sleeve 5 to slide in the reverse direction via the moving block 46. Then, the linkage sleeve 5 pushes the mating block 10 to slide in the reverse direction, causing the mating block 10 to move through the engagement of the insert rod 38 and the slot 39. Push plate 8 and push spring 7 slide in opposite directions. Then, mating block 10 drives mating plate 9 to slide in opposite directions along mating groove 6. Then, mating plate 9 drives mating block 10 to converge and reset inward. Then, mating block 10 drives push plate 8 to converge and reset inward through push spring 7. At the same time, mating block 10 drives linkage plate 44 to slide and reset inward along linkage groove 43. Then, the inner wall of push plate 8 contacts the outer wall of connecting sleeve 29. Then, mating block 10 continues to move, and the distance between mating block 10 and push plate 8 is reduced, so that mating plate 9 and push plate 8 press push spring 7 together. At the same time, one end of insertion rod 38 gradually penetrates into slot 39. After push spring 7 is pressed, push plate 8 presses the outer wall of connecting sleeve 29 through the anti-slip sleeve set on the inner side. At the same time, locking rail 33 and locking The groove 34 drives the clamping block 17 to rotate in the opposite direction to the original two positioning blocks 21. Then, the clamping spring 16 resets and pulls the clamping block 17 to slide inward, so that the clamping block 17 drives the clamping wheel 32 to engage between the original two positioning blocks 21. Then, the movable plate 20 rotates forward again, so that the movable plate 20 drives the movable hole 13 and the movable groove 14 to rotate forward again. The movable block 15 drives the arc rod 35 to rotate forward along the arc hole 36. The movable block 15 and the fixed block 12 cooperate again to press the arc spring 80. When the movable hole 13 rotates to the position concentric with the push plate 19, the push spring 40 resets and pushes the clamping sleeve 11, so that the clamping sleeve 11 drives the inner guide block 41 to slide and reset along the guide groove 42, and clamps. The sleeve 11 is slidably reset by the push rod 18 driving the two push plates 19 to slide back to their original positions. Then, the push plate 19 at the top of the push rod 18 moves back to the original side of the movable plate 20. Then, the movable plate 20 is released again, and the arc spring 80 pushes the movable block 15 to rotate and reset. Then, the movable block 15 drives the arc rod 35 to rotate and reset along the arc hole 36. The movable block 15 drives the movable hole 13 and the movable groove 14 to rotate and reset to a position that does not correspond to the push rod 18 and the push plate 19 through the movable plate 20. Then, the push rod 18 and the push plate 19 at its end form a limiting support for the clamping sleeve 11. With the guide block 41 and the guide groove 42 limiting the rotation of the clamping sleeve 11, the clamping sleeve 11 cannot slide. Then, the inner wall of the clamping sleeve 11 limits the outer side of the clamping wheel 32.This prevents the clamping block 17 and clamping wheel 32 from moving outwards, thus limiting the rotation of the rotating sleeve 3, ensuring structural stability, and guaranteeing stable operation of the equipment.
