Description

Technical Field

[0001] This utility model relates to the field of waste paper transfer technology, and more specifically, to a waste paper transfer device. Background Technology

[0002] In existing technologies, waste paper transfer devices, as key equipment in the paper industry and waste paper recycling systems, are widely used in waste paper processing flows such as collection, sorting, compression, and transfer. By transferring collected waste paper from upstream equipment to downstream equipment or to designated storage locations, they provide important guarantees for the efficient recycling of waste paper resources, centralized supply of papermaking raw materials, environmental protection, and resource recycling. In the actual operation of waste paper transfer devices, pipelines are typically used to connect the transfer device to both upstream and downstream equipment, forming a complete waste paper conveying channel to achieve continuous conveying and transfer of waste paper materials. After waste paper collection is complete, the transfer vehicle needs to be disconnected from the upstream and downstream equipment for further transfer operations. However, in existing technologies... Pipeline connection methods generally suffer from drawbacks such as complex connection and disassembly operations, strong tool dependence, and insufficient flexibility. Connecting and disconnecting pipelines usually requires the assistance of specialized tools such as wrenches, screwdrivers, and pipe wrenches. Operators need to install and disassemble each connecting component, such as fastening bolts, at the pipe joints one by one. The entire operation is cumbersome and time-consuming. At waste paper transfer sites, if the tools are not complete or the tool models and specifications are incompatible, it is easy to make it impossible to connect and disconnect pipelines in a timely manner. This affects the rapid docking and separation between the waste paper transfer device and the upstream and downstream equipment, limits the flexible scheduling and rapid transfer capability of the transfer vehicle between different work sites, and affects the flexibility and convenience of use of the waste paper transfer device.

[0003] Secondly, although some waste paper transfer devices on the market achieve tool-free and convenient connection and disassembly of pipes by setting up multiple components, these existing tool-free connection devices generally have defects such as simple connection structure design and imperfect locking mechanism. After the pipes are connected without tools, their connection structure is easily affected by various external forces and equipment operation factors such as the impact force generated by the transport of waste paper materials and the tensile stress generated by the pipe's own weight during the waste paper transfer operation. This can cause the originally connected pipe connection structure to loosen and shift, or even the connecting parts to fall off unexpectedly. As a result, the pipes lose effective connection constraints, leading to problems such as gaps at pipe joints causing waste paper material leakage, complete pipe detachment causing transport interruption, and connection parts falling off causing unusable conditions. These issues affect the safety and stability of the pipe connection of the waste paper transfer device and the reliability of the transfer operation. Utility Model Content

The horizontal plate is provided in three places. An operating plate is rotatably provided on the outside of the external tube. An operating groove is opened on the operating plate. A cooperating block is fixed on one side of the operating plate. A cooperating spring is connected between the cooperating block and the fitting block. A stroke frame is fixed on the outside of the external tube. A stroke rod is rotatably provided in the stroke frame. Multiple stroke grooves are opened on one side of the release sleeve. One end of the stroke rod is inserted into the stroke groove. A running groove is opened on the inner side of the release sleeve in a variable diameter manner. A running plate is slidably provided in the running groove. A locking rod is fixedly connected to one side of the running plate. A locking groove is opened on the outside of the embedded tube. One end of the locking rod is inserted into the locking groove.

[0006] The present invention is further configured such that: an observation window is provided on the side wall of the transfer vehicle; a slide rail is fixedly provided on one side of the transfer vehicle; an opening and closing cover is slidably provided in the slide rail; a handle is fixedly provided on one side of the opening and closing cover; a universal wheel assembly is installed at the bottom of the transfer vehicle; and a push handle is installed on one side of the transfer vehicle.

[0007] The present invention is further configured such that a spring is movably sleeved on the outside of the external tube, and one end of the spring is connected to the locking sleeve.

[0008] The present invention is further configured such that a collaborative rod is connected to one side of the collaborative block, a collaborative hole is opened in the fitting block, the collaborative spring is movably sleeved on the outside of the collaborative rod, and one end of the collaborative rod slides into the collaborative hole.

[0009] The present invention is further configured such that one end of the locking rod and the inner wall of the locking groove are both designed with a chamfered structure, a rubber sleeve is detachably provided on the inner side of the external tube, multiple rubber rings are provided on the outer side of the embedded tube, and multiple sealing grooves are opened on the inner side of the external tube, with the rubber rings being inserted into the corresponding sealing grooves.

[0010] The present invention is further configured such that a sliding groove is provided on the outer side of the external tube, a sliding block is slidably provided in the sliding groove, and the sliding block is fixedly installed on the inner side of the locking sleeve.

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

[0012] The present invention is further provided with a plurality of anti-slip strips fixedly provided on the outer side of the release sleeve.

[0013] (III) Beneficial Effects Compared with the prior art, the present invention provides a waste paper transfer device, which has the following beneficial effects: 1. Through the coordinated operation of components such as the external pipe, release sleeve, running plate, and locking rod, tool-free and convenient connection and quick disassembly of pipes are achieved. When the operator needs to disconnect the embedded pipe from the external pipe, rotating the release sleeve forward causes the running groove with a variable diameter to rotate forward, moving the running plate in the running groove. The running plate then drives the locking rod to slide outward, gradually disengaging the locking rod from the locking groove. Pulling out the embedded pipe removes it. The operator only needs to rotate the release sleeve and pull out the embedded pipe to quickly connect and disconnect pipes according to the needs of waste paper transfer operations. There is no need to use special tools such as wrenches, screwdrivers, and pipe wrenches to install and disassemble the connecting parts. This effectively avoids the problems of traditional connection methods that require tools for disassembly and assembly, which are cumbersome and time-consuming, and the inability to connect or disconnect in a timely manner due to incompatible tool models. This improves the flexible scheduling capability and rapid transfer efficiency of the waste paper transfer device in different operating locations.

[0014] 2. A multi-layered stable locking mechanism is established through the locking sleeve's engagement with the stroke rod, stroke frame, and stroke groove, the locking of the engaging rod and engaging groove, the rotational constraint of the release sleeve, and the support and fixation of the locking sleeve by the vertical and horizontal plates. After connection, the release sleeve is rotated in the reverse direction, causing the release sleeve to drive the stroke groove and running groove to rotate in the reverse direction and reset. The running plate slides and resets in the running groove, driving the engaging rod to slide and reset inward, so that the engaging rod re-engages in the engaging groove. The engaging rod drives the embedded tube through the engaging groove to press the rubber sleeve, and the rubber ring is simultaneously engaged in the sealing groove. The release sleeve drives the stroke groove to rotate and reset completely to the position corresponding to the stroke rod. The forward rotation of the operating plate causes the operating plate to drive the operating groove and thrust bearing to rotate in the forward direction. When the operating groove rotates to the position corresponding to the horizontal plate, the spring spring resets and pushes the locking sleeve to drive the vertical and horizontal plates to slide and reset. One end of the locking sleeve pushes the corresponding end of the stroke rod outward, causing... The stroke lever rotates in the reverse direction to reset within the stroke frame, and the other end of the stroke lever re-engages into the stroke groove. The spring is fully reset, and the horizontal plates move back to both sides of the operating plate. The reverse operating plate causes the operating groove to reverse and reset again. The vertical plate, in conjunction with the horizontal plate, supports the locking sleeve to one side of the operating plate to prevent the locking sleeve from moving easily. The locking sleeve, stroke lever, stroke frame, and stroke groove work together to limit the rotation of the release sleeve, preventing accidental rotation of the release sleeve. This multi-layer locking mechanism effectively resists the impact force generated by the conveying of waste paper materials and the tensile stress generated by the weight of the pipeline. It effectively prevents the connection structure from loosening and shifting or the connection parts from accidentally falling off. It avoids problems such as gaps at the pipe joints caused by loose connection structure leading to waste paper material leakage, complete pipe detachment leading to conveying interruption, and connection parts falling off leading to unusability. This improves the safety and stability of the pipeline connection of the waste paper transfer device. Attached Figure Description

An embedded pipe 7 is detachably mounted inside the external pipe 5. A release sleeve 8 is rotatably mounted on the outside of the external pipe 5. A locking sleeve 9 is slidably mounted on the outside of the external pipe 5. A vertical plate 10 is fixedly connected to one side of the locking sleeve 9. A horizontal plate 11 is fixedly mounted on one side of the vertical plate 10. The horizontal plate 11 has three locations. The external pipe 5 rotates... An operating plate 12 is provided, and an operating groove 13 is provided on the operating plate 12. A coordinating block 14 is fixedly provided on one side of the operating plate 12. A coordinating spring 15 is connected between the coordinating block 14 and the fitting block 6. A stroke frame 16 is fixedly provided on the outside of the external tube 5. A stroke rod 17 is rotatably provided in the stroke frame 16. A plurality of stroke grooves 18 are provided on one side of the release sleeve 8. One end of the stroke rod 17 is inserted into the stroke groove 18. A running groove 19 is provided on the inner side of the release sleeve 8 in a variable diameter manner. A running plate 20 is slidably provided in the running groove 19. A locking rod 21 is fixedly connected to one side of the running plate 20. A locking groove 22 is provided on the outside of the embedded tube 7. One end of the locking rod 21 is inserted into the locking groove 22.

[0021] The side wall of the transfer vehicle 1 is provided with an observation window 23. A slide rail 24 is fixedly provided on one side of the transfer vehicle 1. An opening and closing cover 25 is slidably provided in the slide rail 24. A handle 26 is fixedly provided on one side of the opening and closing cover 25. A universal wheel assembly 27 is installed at the bottom of the transfer vehicle 1. A push handle 28 is installed on one side of the transfer vehicle 1.

[0022] In this embodiment, when the device is needed, the transfer cart 1 is first pushed by the push handle 28, so that the transfer cart 1 is moved to a suitable position via the bottom universal wheel assembly 27. Then, the transfer cart 1 is stopped and fixed in place. Then, the external pipe 5 on one side of the input pipe 4 is connected to the embedded pipe 7 on one end of the external pre-processing device. Then, the external pipe 5 on one side of the transfer cart 1 is connected to the embedded pipe 7 on one end of the external rear negative pressure conveying device. Then, the rear negative pressure conveying device is turned on to draw the transfer cart 1 into a negative pressure state, so that the waste paper scraps in the pre-collection device are transported into the transfer cart 1 through the embedded pipe 7 and the input pipe 4. The filter plate 2 is set to prevent the waste paper scraps from being drawn into the conveying pipe connected to the rear negative pressure conveying device. After collection is complete, turn off the post-negative pressure conveying equipment and disconnect the transfer cart 1 from both the external pre- and post-equipment devices. Then, release the brake device and push the transfer cart 1 again using the push handle 28, allowing it to move via the bottom universal wheel assembly 27 for transport. Once the cart has reached the desired position, brake and secure it again. Then, slide the handle 26 up to open the cover 25, causing it to move upwards along the slide rail 24, connecting the interior of the transfer cart 1 to the outside. Due to the tilted design of the sliding block 3, most of the waste paper scraps will slide out of the transfer cart 1 into the subsequent collection and processing equipment due to gravity. The interior of the transfer cart 1 can then be thoroughly emptied using tools such as a broom. Finally, release the handle 26 to open the cover. Due to gravity, the cover 25 slides down the slide rail 24, causing the opening and closing cover 25 to re-close the internal space of the transfer car 1. When the transfer car 1 needs to be disconnected from the pre-processing equipment and the post-negative pressure conveying equipment to transfer waste paper, the operating plate 12 is rotated forward first. Then, the operating plate 12 will drive the cooperating block 14 on one side to rotate forward. Then, the cooperating block 14 will drive the cooperating rod 30 on one side to rotate forward along the cooperating hole 31. The cooperating block 14 will cooperate with the matching block 6 to squeeze the cooperating spring 15. At the same time, the operating plate 12 will drive the operating groove 13 and the thrust bearing 37 on one side to rotate forward. When the cooperating spring 15 is squeezed to the limit, the operating groove 13 will rotate forward to the position corresponding to the horizontal plate 11, and then push the locking sleeve 9. This causes the locking sleeve 9 to slide along the sliding groove 35, causing the inner sliding block 36 to slide along the sliding groove 35. Simultaneously, the locking sleeve 9, along with the vertical plate 10 and horizontal plate 11 on one side, gradually slides into the operating groove 13. At the same time, the locking sleeve 9, in conjunction with the thrust bearing 37, compresses the spring 29. During this process, the outer wall of the locking sleeve 9 gradually stops limiting one end of the travel rod 17. When the spring 29 is compressed to its limit, the horizontal plate 11 closest to the locking sleeve 9 slides through the operating groove 13 and moves to the other side of the operating plate 12. Then, the operating plate 12 is released, causing the cooperating spring 15 to reset and push the cooperating block 14. The cooperating block 14 then causes one side of the cooperating rod 30 to reverse along the cooperating hole 31.Simultaneously, the coordinating block 14 drives the operating groove 13 and thrust bearing 37 to rotate in the opposite direction and reset via the operating plate 12. When the operating groove 13 rotates to a position that does not correspond to the vertical plate 10 and the horizontal plate 11, the operating plate 12 stops rotating. At this time, the vertical plate 10, in conjunction with the horizontal plate 11 closest to the locking sleeve 9, limits the locking sleeve 9 to one side of the operating plate 12, so that the outer wall of the locking sleeve 9 is not limited at one end of the stroke rod 17. Then, the release sleeve 8 rotates in the forward direction, which drives the multiple stroke grooves 18 opened on one side to rotate. Then, the inner wall of the stroke groove 18 presses against one end of the stroke rod 17. Due to the arc angle design of the inner wall of the stroke groove 18 and the end of the stroke rod 17, as well as the rotational connection between the stroke rod 17 and the stroke frame 16, then... The travel groove 18 pushes one end of the travel rod 17 out, causing the travel rod 17 to rotate within the travel frame 16, and the other end of the travel rod 17 to rotate inward. Simultaneously, the release sleeve 8 drives the inner variable-diameter running groove 19 to rotate forward, causing the running plate 20 to move within the running groove 19. The running plate 20 then drives the locking rod 21 connected to one side to slide outward, gradually disengaging the locking rod 21 from the locking groove 22. Then, the embedded tube 7 is pulled outward, disconnecting the transfer cart 1 from the front-end equipment and the rear-end equipment. The transfer cart 1 can then be pushed by the push handle 28 to transfer the internally collected waste paper. The outer ends of the two embedded tubes 7 are connected to the external front-end equipment and the rear-end equipment respectively via external corrugated pipes.

[0023] Please see Figures 3-5 As a further implementation of the overall device: a spring 29 is movably sleeved on the outside of the external tube 5, and one end of the spring 29 is connected to the locking sleeve 9. A coordinating rod 30 is connected to one side of the coordinating block 14, and a coordinating hole 31 is opened in the fitting block 6. The coordinating spring 15 is movably sleeved on the outside of the coordinating rod 30, and one end of the coordinating rod 30 slides into the coordinating hole 31.

[0024] Both the locking rod 21 and the inner wall of the locking groove 22 are designed with a chamfered structure. The inner side of the external tube 5 is provided with a detachable rubber sleeve 32. The outer side of the embedded tube 7 is provided with multiple rubber rings 33. The inner side of the external tube 5 is provided with multiple sealing grooves 34. The rubber rings 33 are inserted into the corresponding sealing grooves 34.

[0025] The outer side of the external tube 5 is provided with a sliding groove 35, and a sliding block 36 is slidably provided in the sliding groove 35. The sliding block 36 is fixedly installed inside the locking sleeve 9.

[0026] A thrust bearing 37 is detachably mounted on one side of the operating plate 12, and the other end of the spring 29 is connected to the thrust bearing 37.

[0027] Multiple anti-slip strips 38 are fixed on the outer side of the release sleeve 8.

[0028] More specifically, when it is necessary to connect the embedded tube 7 to the external tube 5, one end of the embedded tube 7 is inserted into the external tube 5, and the outer wall of the embedded tube 7 abuts against the rubber sleeve 32 provided on the inner side of the external tube 5. Then, the release sleeve 8 is rotated in the opposite direction, causing the release sleeve 8 to drive the multiple stroke grooves 18 opened on one side to rotate in the opposite direction. At the same time, the release sleeve 8 will drive the inner variable diameter running groove 19 to rotate in the opposite direction and reset. Then, the running plate 20 slides and resets in the running groove 19, and the running plate 20 will drive the locking rod 21 to slide and reset inward, so that the locking rod 21 is re-locked into the locking groove 22. Due to the chamfer design of one end of the locking rod 21 and the inner wall of the locking groove 22, after the locking rod 21 is re-locked into the locking groove 22, the locking rod 21 passes through the locking groove 22. 2. The embedded tube 7 is driven to press the rubber sleeve 32, and the multiple rubber rings 33 on the outside of the embedded tube 7 are simultaneously inserted into the corresponding sealing grooves 34. At the same time, the release sleeve 8 drives the stroke groove 18 to rotate and reset. At this time, the corresponding stroke groove 18 rotates to the position corresponding to the original stroke rod 17. Then, the operating plate 12 is rotated forward again, so that the operating plate 12 drives the side cooperating block 14 to rotate forward again. Then, the cooperating block 14 drives the side cooperating rod 30 to rotate forward along the cooperating hole 31. The cooperating block 14 and the matching block 6 cooperate again to squeeze the cooperating spring 15. At the same time, the operating plate 12 drives the operating groove 13 and the thrust bearing 37 on one side to rotate forward again. When the operating groove 13 rotates forward again to the position corresponding to the horizontal plate 11, the spring spring 2 is compressed. 9 will push the locking sleeve 9 to drive the inner sliding block 36 to slide and reset along the sliding groove 35 in the opposite direction. The locking sleeve 9 will also drive the vertical plate 10 and the three horizontal plates 11 to slide and reset. Simultaneously, due to the chamfered design at one end of the locking sleeve 9 and the arc-shaped design at the end of the stroke rod 17, the locking sleeve 9 will gradually push the corresponding end of the stroke rod 17 outwards. Then, the stroke rod 17 will rotate and reset in the stroke frame 16, causing the other end of the stroke rod 17 to re-engage into the original stroke groove 18. At this point, the spring 29 is fully reset, and the other two horizontal plates 11 have moved and reset to their original positions on both sides of the operating plate 12. Then, the operating plate 12 is released again, causing the cooperating spring 15 to reset again, pushing the cooperating block 14 to reverse and reset. Block 14 will once again drive the coordinating rod 30 on one side to reverse and reset along the coordinating hole 31. At the same time, the coordinating block 14 will once again drive the operating groove 13 and the thrust bearing 37 on one side to reverse and reset through the operating plate 12. This will cause the operating groove 13 to reverse and reset again to a position that does not correspond to the vertical plate 10 and the horizontal plate 11. Then, the vertical plate 10, together with the corresponding two horizontal plates 11, will support and limit the locking sleeve 9 to one side of the operating plate 12. With the sliding block 36 and the sliding groove 35 limiting the locking sleeve 9, the locking sleeve 9 is prevented from moving. At this time, the locking sleeve 9, together with the stroke rod 17, the stroke bracket 16 and the stroke groove 18, will form a rotation limit on the release sleeve 8 to prevent the release sleeve 8 from rotating accidentally. This achieves a convenient and stable connection between the embedded tube 7 and the external tube 5.

[0029] In summary, when using or operating the entire device: First, push the transfer cart 1 using the push handle 28 to move it to a suitable position via the bottom caster assembly 27. Then, stop and fix the transfer cart 1 in place. Next, connect the external pipe 5 on one side of the input pipe 4 to the embedded pipe 7 on one end of the external pre-processing device. Then, connect the external pipe 5 on one side of the transfer cart 1 to the embedded pipe 7 on one end of the external post-negative pressure conveying device. Finally, open the post-negative pressure conveying device to create a negative pressure state inside the transfer cart 1, allowing waste paper scraps from the pre-collection device to be conveyed into the transfer cart 1 through the embedded pipe 7 and the input pipe 4. The filter plate 2 prevents waste paper scraps from being drawn into the conveying device connected to the post-negative pressure conveying device. In the pipeline, after collection is complete, the post-negative pressure conveying equipment is shut off, and the transfer cart 1 is disconnected from both the pre- and post-external equipment. The braking device is then released, and the transfer cart 1 is pushed again via the push handle 28, allowing it to move via the bottom universal wheel assembly 27 for transport. Once transported to the appropriate position, it is braked again and secured. The cover 25 is then slid open via the handle 26, allowing it to move upwards along the slide rail 24, connecting the interior of the transfer cart 1 to the outside. Due to the inclined design of the sliding block 3, most of the waste paper scraps will slide out of the transfer cart 1 into the subsequent collection and processing equipment due to gravity. The interior of the transfer cart 1 can then be thoroughly emptied using tools such as a broom. Finally, the handle 26 is released. The opening and closing cover 25 slides down the slide rail 24 due to gravity, causing the opening and closing cover 25 to re-close the internal space of the transfer car 1. When the transfer car 1 needs to be disconnected from the pre-processing equipment and the post-negative pressure conveying equipment to transfer waste paper, the operating plate 12 is rotated forward first. Then, the operating plate 12 will drive the cooperating block 14 on one side to rotate forward. Then, the cooperating block 14 will drive the cooperating rod 30 on one side to rotate forward along the cooperating hole 31. The cooperating block 14 will cooperate with the matching block 6 to squeeze the cooperating spring 15. At the same time, the operating plate 12 will drive the operating groove 13 and the thrust bearing 37 on one side to rotate forward. When the cooperating spring 15 is squeezed to the limit, the operating groove 13 will rotate forward to the position corresponding to the horizontal plate 11, and then push the locking mechanism. The locking sleeve 9 causes the inner sliding block 36 to slide along the sliding groove 35, and causes the locking sleeve 9 to gradually slide the vertical plate 10 and horizontal plate 11 into the operating groove 13. At the same time, the locking sleeve 9 cooperates with the thrust bearing 37 to compress the spring 29. During this process, the outer wall of the locking sleeve 9 will gradually stop limiting one end of the stroke rod 17. When the spring 29 is compressed to its limit, the horizontal plate 11 closest to the locking sleeve 9 just slides through the operating groove 13 and moves to the other side of the operating plate 12. Then the operating plate 12 is released, causing the cooperating spring 15 to reset and push the cooperating block 14. Then the cooperating block 14 causes the cooperating rod 30 on one side to rotate in reverse, and the cooperating block 14 will also cause the cooperating rod 30 on one side to rotate in reverse along the cooperating hole 31.Simultaneously, the coordinating block 14 drives the operating groove 13 and thrust bearing 37 to rotate in the opposite direction and reset via the operating plate 12. When the operating groove 13 rotates to a position that does not correspond to the vertical plate 10 and the horizontal plate 11, the operating plate 12 stops rotating. At this time, the vertical plate 10, in conjunction with the horizontal plate 11 closest to the locking sleeve 9, limits the locking sleeve 9 to one side of the operating plate 12, so that the outer wall of the locking sleeve 9 is not limited at one end of the stroke rod 17. Then, the release sleeve 8 rotates in the forward direction, which drives the multiple stroke grooves 18 opened on one side to rotate. Then, the inner wall of the stroke groove 18 presses against one end of the stroke rod 17. Due to the arc angle design of the inner wall of the stroke groove 18 and the end of the stroke rod 17, as well as the rotational connection between the stroke rod 17 and the stroke frame 16, then... The travel groove 18 pushes one end of the travel rod 17 out, causing the travel rod 17 to rotate within the travel frame 16, and the other end of the travel rod 17 to rotate inward. Simultaneously, the release sleeve 8 drives the inner variable-diameter running groove 19 to rotate forward, causing the running plate 20 to move within the running groove 19. The running plate 20 then drives the locking rod 21 connected to one side to slide outward, gradually disengaging the locking rod 21 from the locking groove 22. Then, the embedded tube 7 is pulled outward, disconnecting the transfer cart 1 from the front-end equipment and the rear-end equipment. The transfer cart 1 can then be pushed by the push handle 28 to transfer the internally collected waste paper. The outer ends of the two embedded tubes 7 are connected to the external front-end equipment and the rear-end equipment respectively via external corrugated pipes.

[0030] When it is necessary to connect the embedded tube 7 to the external tube 5, one end of the embedded tube 7 is inserted into the external tube 5, and the outer wall of the embedded tube 7 abuts against the rubber sleeve 32 provided on the inner side of the external tube 5. Then, the release sleeve 8 is rotated in the opposite direction, causing the release sleeve 8 to drive the multiple travel grooves 18 opened on one side to rotate in the opposite direction. At the same time, the release sleeve 8 will drive the inner variable diameter running groove 19 to rotate in the opposite direction and reset. Then, the running plate 20 slides and resets in the running groove 19, and the running plate 20 will drive the locking rod 21 to slide and reset inward, so that the locking rod 21 is re-engaged in the locking groove 22. Due to the chamfer design of one end of the locking rod 21 and the inner wall of the locking groove 22, when the locking rod 21 is re-engaged in the locking groove 22, the locking rod 21 drives the embedded tube 7 to rotate in the opposite direction through the locking groove 22. The inlet tube 7 presses the rubber sleeve 32 tightly, and the multiple rubber rings 33 embedded on the outside of the inlet tube 7 are simultaneously inserted into the corresponding sealing grooves 34. At the same time, the release sleeve 8 drives the stroke groove 18 to rotate and reset. At this time, the corresponding stroke groove 18 rotates to the position corresponding to the original stroke rod 17. Then, the operating plate 12 rotates forward again, causing the operating plate 12 to drive the side cooperating block 14 to rotate forward again. Then, the cooperating block 14 drives the side cooperating rod 30 to rotate forward along the cooperating hole 31. The cooperating block 14 and the matching block 6 cooperate again to squeeze the cooperating spring 15. At the same time, the operating plate 12 drives the operating groove 13 and the thrust bearing 37 on one side to rotate forward again. When the operating groove 13 rotates forward again to the position corresponding to the horizontal plate 11, the spring spring 29 will push. The locking sleeve 9 drives the inner sliding block 36 to slide and reset in the reverse direction along the sliding groove 35. The locking sleeve 9 also drives the vertical plate 10 on one side and the three horizontal plates 11 to slide and reset. Simultaneously, due to the chamfered design at one end of the locking sleeve 9 and the arc-shaped design at the end of the stroke rod 17, the locking sleeve 9 gradually pushes the corresponding end of the stroke rod 17 outwards. The stroke rod 17 then rotates and resets in the stroke frame 16, causing the other end of the stroke rod 17 to re-enter the original stroke groove 18. At this point, the spring 29 is fully reset, and the other two horizontal plates 11 have moved and reset to their original positions on both sides of the operating plate 12. Then, the operating plate 12 is released again, causing the cooperating spring 15 to reset again, pushing the cooperating block 14 to reverse and reset. 4 will again drive the coordinating rod 30 on one side to reverse and reset along the coordinating hole 31. At the same time, the coordinating block 14 will drive the operating groove 13 and the thrust bearing 37 on one side to reverse and reset through the operating plate 12. This will cause the operating groove 13 to reverse and reset to a position that does not correspond to the vertical plate 10 and the horizontal plate 11. Then, the vertical plate 10, together with the corresponding two horizontal plates 11, will support and limit the locking sleeve 9 to one side of the operating plate 12. With the sliding block 36 and the sliding groove 35 limiting the locking sleeve 9, the locking sleeve 9 is prevented from moving. At this time, the locking sleeve 9, together with the stroke rod 17, the stroke bracket 16 and the stroke groove 18, will form a rotation limit on the release sleeve 8 to prevent the release sleeve 8 from rotating accidentally. This achieves a convenient and stable connection between the embedded tube 7 and the external tube 5.
