Description

Technical Field

[0001] This application belongs to the technical field of waterproof layer laying, specifically relating to a waterproof membrane laying device for irregular surfaces. Background Technology

[0002] Underground engineering refers to various structures built in the soil or rock layers below the surface for the development and utilization of underground space. There is an inseparable and mutually restrictive symbiotic relationship between the development and utilization of underground space and waterproofing engineering. Waterproofing is the basic prerequisite for the safety, durability and functional realization of underground space, while the development depth, scale and use of underground space constantly pose new challenges and requirements to waterproofing technology.

[0003] Currently, to address the chain reaction of risks such as structural instability, power outages, and data loss caused by leakage in underground engineering projects, waterproof membranes are typically laid to prevent leaks and ensure the waterproofing performance of the underground structures. However, due to the presence of irregular surfaces such as internal and external corners in underground engineering projects, existing laying tools are only capable of laying waterproof membranes on flat surfaces. This affects the efficiency and quality of waterproof membrane laying in underground engineering projects. Therefore, improving the efficiency and quality of waterproof membrane laying in underground engineering projects has become an urgent technical problem to be solved. Utility Model Content

[0004] This application provides a waterproof membrane laying device for irregular surfaces to improve the efficiency and quality of waterproof membrane laying in underground engineering.

[0005] The technical solution adopted in this application is as follows: A waterproof membrane laying device for irregularly shaped surfaces includes: Support frame, the support frame having a passage opening; A laying roller assembly includes a first roller and a second roller. The first roller includes a first support shaft and a first roller body sleeved outside the first support shaft. The second roller includes a second support shaft and a second roller body sleeved outside the second support shaft. The second support shaft is fixedly connected to the first support shaft and the two are arranged at an included angle. Both the first support shaft and the second support shaft are rotatably connected to the support frame so that the first roller and the second roller can rotate to the outside of the support frame through the through-hole. A locking assembly is disposed on the support frame and is used to lock the first support shaft and the second support shaft.

[0006] By adopting the above technical solution, when laying waterproof membrane at the external corner, the waterproof membrane is first placed at the external corner, and then the waterproof membrane laying device of this application is used to roll the waterproof membrane to make the waterproof membrane adhere to the external corner; when using the waterproof membrane laying device to roll the waterproof membrane, the waterproof membrane laying device is first placed on the side of the waterproof membrane away from the external corner, and then pressure is applied to the waterproof membrane laying device towards the side of the external corner, so that the waterproof membrane laying device abuts against the waterproof membrane and applies pressure towards the external corner, thereby making the waterproof membrane abut against the wall surface at the external corner, and then the waterproof membrane laying device is pushed back and forth along the extension direction of the external corner, so that the waterproof membrane laying device rolls the waterproof membrane multiple times to complete the laying of the waterproof membrane at the external corner.

[0007] When laying waterproof membrane at the inside corner, first operate the locking assembly to unlock the first and second support shafts. Then, rotate the first and second support shafts to drive the first and second rollers to rotate, causing them to rotate through the through-hole to the outside of the support frame. This ensures that the included angle formed by the first and second support shafts is outside the support frame. Then, operate the locking assembly to lock the first and second support shafts, thus locking the first and second rollers. Next, place the waterproof membrane at the inside corner and then apply this application. The waterproof membrane laying device rolls the waterproof membrane to adhere it to the inside corner. When using the waterproof membrane laying device to roll the waterproof membrane, first place the device on the side of the waterproof membrane away from the inside corner, then apply pressure towards the inside corner to make the device contact the waterproof membrane and apply pressure towards the inside corner, thus making the waterproof membrane contact the wall surface at the inside corner. Then, the device is pushed back and forth along the extension direction of the inside corner to roll the waterproof membrane multiple times, completing the laying of the waterproof membrane at the inside corner.

[0008] In summary, the waterproof membrane laying device for irregular surfaces in this application can not only assist workers in laying waterproof membrane at external corners, but also assist workers in laying waterproof membrane at internal corners. It can not only improve the efficiency of laying waterproof membrane in underground projects, but also improve the quality of waterproof membrane laying, thereby greatly improving the waterproof performance of underground projects.

[0011] Optionally, the laying roller assembly further includes a connector located between the first roller and the second roller, wherein both the first support section and the second support section are fixedly connected to the connector.

[0012] By adopting the above technical solution, since the connector is located between the first roller and the second roller, and both the first support section and the second support section are fixedly connected to the connector, on the one hand, the connection stability of the first support shaft and the second support shaft can be increased to ensure the connection stability of the first roller and the second roller. On the other hand, it can also facilitate the installation of the first roller body and the second roller body, thereby reducing the assembly difficulty of the waterproof membrane laying device and improving the production efficiency of the waterproof membrane laying device.

[0013] Optionally, the connector has a connecting shaft, the central axis of which is parallel to the first rotating segment and the second rotating segment, and the connector is provided with a connecting ring sleeved on the outside of the connecting shaft.

[0014] By adopting the above technical solution, since the connector has a connecting shaft, the central axis of the connecting shaft is set parallel to the first rotating segment and the second rotating segment, and the connector is provided with a connecting ring sleeved on the outside of the connecting shaft, and the locking component is connected to the connecting ring to lock the first support shaft and the second support shaft through the connecting ring, thereby reducing the difficulty of locking the first support shaft and the second support shaft, thereby improving the adjustment and locking efficiency of the first roller and the second roller, and also enabling the connecting ring and the connector to rotate relative to each other, so that when laying the waterproof membrane at the inside corner, the connecting ring can avoid the inside corner, thereby ensuring the laying quality of the waterproof membrane at the inside corner.

[0015] Optionally, the connecting ring extends to include an extension portion with a connecting hole, and the locking assembly is connected to the connecting hole via a bolt pair.

[0016] By adopting the above technical solution, since the extension is provided with a connection hole, the locking assembly is connected to the connection hole by a bolt pair. This enables the connection between the extension and the locking assembly to lock the first support shaft and the second support shaft. On the other hand, it also reduces the difficulty and stability of locking the first support shaft and the second support shaft by the locking assembly, thereby improving the adjustment efficiency of the first roller and the second roller and increasing the stability of the first roller and the second roller.

[0017] Optionally, the locking assembly includes a locking rod passing through the support frame and a locking block disposed on the locking rod. The locking block is provided with a locking hole, and the locking hole is connected to the connecting hole by a bolt pair.

[0018] By adopting the above technical solution, when adjusting the first roller and the second roller, the nut of the bolt pair is first tightened to separate the nut from the bolt, and then the bolt is removed to separate the bolt from the locking hole and the connecting hole. Then, a thrust is applied to the locking rod away from the first roller and the second roller to make the locking rod slide relative to the support frame, and at the same time, the locking block is separated from the extension. Then, the first support shaft and the second support shaft are rotated so that the first support shaft and the second support shaft drive the first roller body and the second roller body to rotate respectively. When the first support shaft and the second support shaft are rotated to the desired position, the rotation of the first support shaft and the second support shaft is stopped. Then, the locking rod is pushed towards the side where the first support shaft and the second support shaft are located so that the locking block moves to the position where the extension is located, so that the locking hole and the connecting hole are aligned. Then, the bolt pair is installed so that the bolt pair passes through the locking hole and the connecting hole to complete the adjustment of the first roller and the second roller.

[0019] Optionally, the locking block is provided with a receiving groove, and the extension is located in the receiving groove.

[0020] By adopting the above technical solution, since the locking block is provided with a receiving groove and the extension is located in the receiving groove, on the one hand, the connection area between the extension and the locking block can be increased to increase the connection stability between the locking block and the extension; on the other hand, the locking block can be used to support the extension to further increase the stability of the extension.

[0021] Optionally, the support frame has a guide tube on the side opposite to the passage, and the locking rod passes through the guide tube.

[0022] By adopting the above technical solution, since the support frame has a guide tube on the side away from the passage, and the locking rod passes through the guide tube, the locking rod can be guided by the guide tube to increase the stability of the locking rod when sliding. On the other hand, the locking rod can be limited and positioned by the guide tube to increase the connection stability between the locking rod and the support frame, thereby increasing the locking effect of the locking assembly on the first support shaft and the second support shaft.

[0023] Optionally, the support frame is provided with a support member, the locking rod passes through the support member, and the support member can slide relative to the support frame.

[0024] By adopting the above technical solution, since the support frame is provided and the locking rod passes through the support member, the locking rod can be supported by the support member to increase the stability of the locking rod, thereby increasing the stability of the first roller and the second roller; and since the support member can slide relative to the support frame, the support member can be adjusted to support the locking rod at different positions, thereby increasing the flexibility of the support member.

[0025] Optionally, the support member is provided with a through hole, the outer peripheral surface of the locking rod is provided with a limiting groove, and the locking rod passes through the through hole. The hole wall of the through hole is provided with a receiving cavity, and the receiving cavity is provided with a limiting part that can extend into the limiting groove and an elastic part for applying movement toward the limiting groove to the limiting part.

[0026] By adopting the above technical solution, since the support member is provided with a through hole, the outer peripheral surface of the locking rod is provided with a limiting groove, and the locking rod passes through the through hole, the hole wall of the through hole is provided with a receiving cavity, and the receiving cavity is provided with a limiting part that can extend into the limiting groove and an elastic part for applying movement towards the limiting groove to the limiting part. Thus, on the one hand, the cooperation between the limiting part and the limiting groove can be used to realize that the support member moves with the locking rod, so as to realize the synchronous movement of the support frame and the locking rod, thereby simplifying the user's operation steps. On the other hand, the cooperation between the limiting part and the limiting groove can also be used to limit the relative movement of the support member and the locking rod, thereby increasing the connection stability between the support member and the locking rod, and thus ensuring the support effect of the support member on the locking rod.

[0027] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows: 1. The waterproof membrane laying device of this application includes a support frame, a laying roller assembly, and a locking assembly. The support frame has a passage opening. The laying roller assembly includes a first roller and a second roller. The first roller includes a first support shaft and a first roller body sleeved outside the first support shaft. The second roller includes a second support shaft and a second roller body sleeved outside the second support shaft. The second support shaft is fixedly connected to the first support shaft and the two are arranged at an included angle. Both the first and second support shafts are rotatably connected to the support frame so that the first and second rollers can rotate to the outside of the support frame through the passage opening.

[0037] Reference Figures 1 to 6 A waterproof membrane laying device for irregular surfaces is disclosed, comprising a support frame 1, a laying roller assembly, and a locking assembly 4. The support frame 1 has a passage opening. The laying roller assembly includes a first roller 2 and a second roller 3. The first roller 2 includes a first support shaft 21 and a first roller body 22 sleeved outside the first support shaft 21. The second roller 3 includes a second support shaft 31 and a second roller body 32 sleeved outside the second support shaft 31. The second support shaft 31 is fixedly connected to the first support shaft 21 and the two are arranged at an included angle. Both the first support shaft 21 and the second support shaft 31 are rotatably connected to the support frame 1 so that the first roller 2 and the second roller 3 can rotate to the outside of the support frame 1 through the passage opening. The locking assembly 4 is disposed on the support frame 1 and is used to lock the first support shaft 21 and the second support shaft 31.

[0038] It is understood that the laying roller assembly has a first position where the first roller 2 and the second roller 3 are located inside the support frame 1, and a second position where the first roller 2 and the second roller 3 rotate to the outside of the support frame 1 via the through-hole; when the laying roller assembly is in the first position, the waterproof membrane laying device can lay the waterproof membrane at the external corner; when the laying roller assembly is in the second position, the waterproof membrane laying device can lay the waterproof membrane at the internal corner; the first support shaft 21 and the second support shaft 31 are respectively provided with limiting rings located at the ends of the first roller body 22 and the second roller body 32 to increase the stability of the first roller body 22 and the second roller body 32.

[0039] When laying waterproof membrane at an external corner, first place the waterproof membrane at the corner, and then use the waterproof membrane laying device of this application to roll the waterproof membrane to make it adhere to the corner. When using the waterproof membrane laying device to roll the waterproof membrane, first place the waterproof membrane laying device on the side of the waterproof membrane away from the corner, and then apply pressure to the waterproof membrane laying device towards the corner so that the waterproof membrane laying device abuts against the waterproof membrane and applies pressure towards the corner, thereby making the waterproof membrane abut against the wall surface at the corner. Then, push the waterproof membrane laying device back and forth along the extension direction of the corner so that the waterproof membrane laying device rolls the waterproof membrane multiple times to complete the laying of the waterproof membrane at the external corner.

[0040] When laying waterproof membrane at the inside corner, first operate the locking assembly 4 to unlock the first support shaft 21 and the second support shaft 31. Then, rotate the first support shaft 21 and the second support shaft 31 so that they drive the first roller body 22 and the second roller body 32 to rotate respectively. This causes the first roller 2 and the second roller 3 to rotate to the outside of the support frame 1 through the through-hole, so that the laying roller group moves from the first position to the second position. This makes the included angle formed by the first support shaft 21 and the second support shaft 31 located outside the support frame 1. Then, operate the locking assembly 4 to lock the first support shaft 21 and the second support shaft 31, thereby achieving the locking of the first roller 2 and the second roller 3. The waterproof membrane is then locked in place; then the waterproof membrane is placed at the inside corner, and then the waterproof membrane laying device of this application is used to roll the waterproof membrane to make the waterproof membrane adhere to the inside corner; when using the waterproof membrane laying device to roll the waterproof membrane, first place the waterproof membrane laying device on the side of the waterproof membrane away from the inside corner, and then apply pressure to the waterproof membrane laying device towards the inside corner so that the waterproof membrane laying device abuts against the waterproof membrane and applies pressure towards the inside corner, so that the waterproof membrane abuts against the wall surface at the inside corner, and then push the waterproof membrane laying device back and forth along the extension direction of the inside corner so that the waterproof membrane laying device rolls the waterproof membrane multiple times to complete the laying of the waterproof membrane at the inside corner.

[0041] In summary, the waterproof membrane laying device for irregular surfaces in this application can not only assist workers in laying waterproof membrane at external corners, but also assist workers in laying waterproof membrane at internal corners. It can not only improve the efficiency of laying waterproof membrane in underground projects, but also improve the quality of waterproof membrane laying, thereby greatly improving the waterproof performance of underground projects.

[0042] The better one is to refer to Figure 1and Figure 2 The support frame 1 is C-shaped, that is, the support frame 1 includes a web and wing plates located on both sides of the web. The two wing plates are arranged in parallel and spaced apart and are fixedly connected to the web. The ends of the two wing plates away from the web form a passage. The first support shaft 21 and the second support shaft 31 are rotatably connected to the two wing plates respectively.

[0043] Preferably, the first support shaft 21 and the second support shaft 31 are arranged vertically so that a 90° angle is formed between the central axes of the first roller body 22 and the second roller body 32, so as to further improve the quality of laying waterproof membrane at the external and internal corners.

[0044] In a preferred embodiment, refer to Figure 3 The first support shaft 21 includes a first support section 211 and a first rotating section 212. The first roller body 22 is sleeved on the outside of the first support section 211, and the first rotating section 212 is rotatably connected to the support frame 1. The second support shaft 31 includes a second support section 311 and a second rotating section 312. The second roller body 32 is sleeved on the outside of the second support section 311, and the second rotating section 312 is rotatably connected to the support frame 1 and coaxially arranged with the first rotating section 212.

[0045] It is understandable that the first support segment 211 and the second support segment 311 are set vertically.

[0046] Since the first support shaft 21 includes a first support section 211 and a first rotating section 212, the first roller body 22 is sleeved on the outside of the first support section 211, and the first rotating section 212 is rotatably connected to the support frame 1; the second support shaft 31 includes a second support section 311 and a second rotating section 312, the second roller body 32 is sleeved on the outside of the second support section 311, and the second rotating section 312 is rotatably connected to the support frame 1 and coaxially arranged with the first rotating section 212, it can achieve the effect of facilitating the rotation of the first support shaft 21 and the second support shaft 31, thereby reducing the difficulty of rotating the first roller 2 and the second roller 3 to the outside of the support frame 1, and at the same time ensuring the smoothness of the rotation of the first roller 2 and the second roller 3.

[0047] Furthermore, refer to Figure 3 The first support shaft 21 also includes a first connecting section 213 located between the first support section 211 and the first rotating section 212, the first connecting section 213 being arranged parallel to the wing plate; the second support shaft 31 also includes a second connecting section 313 located between the second support section 311 and the second rotating section 312, the second connecting section 313 being arranged parallel to the wing plate, so that when the laying roller group is in the second position, the first roller body 22 and the second roller body 32 can avoid contact with the end of the wing plate away from the web plate, so as to ensure that when laying waterproof membrane at the inside corner, the end of the wing plate cannot contact the waterproof membrane.

[0048] Furthermore, refer to Figure 3 The laying roller assembly also includes a connector 6 located between the first roller 2 and the second roller 3, and the first support section 211 and the second support section 311 are both fixedly connected to the connector 6.

[0049] Since the connector 6 is located between the first roller 2 and the second roller 3, and both the first support section 211 and the second support section 311 are fixedly connected to the connector 6, it can increase the connection stability of the first support shaft 21 and the second support shaft 31 to ensure the connection stability of the first roller 2 and the second roller 3. On the other hand, it can also facilitate the installation of the first roller body 22 and the second roller body 32, thereby reducing the assembly difficulty of the waterproof membrane laying device and improving the production efficiency of the waterproof membrane laying device.

[0050] Preferably, the connector 6 is a connecting block with a smooth outer contour, so that the connecting block can fill the gap between the first roller 22 and the second roller 32, thereby further improving the laying quality of the waterproof membrane.

[0051] Furthermore, refer to Figure 3 and Figure 4 The connector 6 has a connecting shaft 61, the central axis of which is parallel to the first rotating section 212 and the second rotating section 312. The connector 6 is provided with a connecting ring 62 sleeved on the outside of the connecting shaft 61. The locking component 4 is connected to the connecting ring 62 to lock the first support shaft 21 and the second support shaft 31 through the connecting ring 62. This reduces the difficulty of locking the first support shaft 21 and the second support shaft 31, thereby improving the adjustment and locking efficiency of the first roller 2 and the second roller 3. On the other hand, it also allows the connecting ring 62 to rotate relative to the connector 6, so that when laying the waterproof membrane at the inside corner, the connecting ring 62 can avoid the inside corner, thus ensuring the quality of the waterproof membrane laying at the inside corner.

[0052] Furthermore, refer to Figure 3 and Figure 4 The connecting ring 62 extends to provide an extension portion 63, which has a connecting hole. The locking assembly 4 is connected to the connecting hole by a bolt pair 422. This enables the extension portion 63 to be connected to the locking assembly 4 to lock the first support shaft 21 and the second support shaft 31. It also reduces the difficulty and stability of locking the first support shaft 21 and the second support shaft 31 by the locking assembly 4, thereby improving the adjustment efficiency of the first roller 2 and the second roller 3 and increasing the stability of the first roller 2 and the second roller 3.

[0053] This application does not specifically limit the structure of the locking component 4; preferably, refer to... Figure 1 and Figure 2The locking assembly 4 includes a locking rod 41 that passes through the support frame 1 and a locking block 42 that is provided on the locking rod 41. The locking block 42 is provided with a locking hole, which is connected to the connecting hole through a bolt pair 422.

[0054] It is understandable that the web has a perforated structure, and the locking rod 41 passes through the perforated structure of the web and can slide relative to the web.

[0055] When adjusting the first roller 2 and the second roller 3, first loosen the nut of the bolt pair 422 to separate the nut from the bolt, then remove the bolt to separate it from the locking hole and the connecting hole. Then apply a thrust away from the direction of the first roller 2 and the second roller 3 to the locking rod 41 to make the locking rod 41 slide relative to the support frame 1, and at the same time separate the locking block 42 from the extension 63. Then rotate the first support shaft 21 and the second support shaft 31 so that the first support shaft 21 and the second support shaft 31 drive the first roller body respectively. 22 and the second roller 32 rotate. When the first support shaft 21 and the second support shaft 31 rotate to the required position, the rotation of the first support shaft 21 and the second support shaft 31 is stopped. Then the locking rod 41 is pushed toward the side where the first support shaft 21 and the second support shaft 31 are located, so that the locking block 42 moves to the position where the extension 63 is located, so that the locking hole is opposite to the connecting hole. Then the bolt pair 422 is installed so that the bolt pair 422 passes through the locking hole and the connecting hole to complete the adjustment of the first roller 2 and the second roller 3.

[0056] This application does not impose specific limitations on the structure of the extension 63. Preferably, the extension 63 is a sheet-like structure to simplify the structural design of the extension 63, thereby reducing the manufacturing cost of the waterproof membrane laying device.

[0057] Furthermore, refer to Figure 4 The locking block 42 is provided with a receiving groove 421, and the extension 63 is located in the receiving groove 421.

[0058] It is understandable that when the central axis of the locking hole and the connecting hole are collinear, the extension 63 is located in the receiving groove 421.

[0059] Since the locking block 42 is provided with a receiving groove 421, the extension 63 is located in the receiving groove 421. This increases the connection area between the extension 63 and the locking block 42, thereby increasing the connection stability between the locking block 42 and the extension 63. Furthermore, the locking block 42 can be used to support the extension 63, thereby further increasing the stability of the extension 63.

[0060] Furthermore, refer to Figure 1 and Figure 2The support frame 1 has a guide tube 11 on the side opposite to the passage, and the locking rod 41 passes through the guide tube 11.

[0061] It is understandable that the guide tube 11 is fixedly connected to the web and is set perpendicular to the web.

[0062] Since the support frame 1 has a guide tube 11 on the side away from the passage, the locking rod 41 passes through the guide tube 11. Thus, on the one hand, the guide tube 11 can be used to guide the locking rod 41 to increase the stability of the locking rod 41 when sliding. On the other hand, the guide tube 11 can be used to limit and position the locking rod 41 to increase the connection stability between the locking rod 41 and the support frame 1, thereby increasing the locking effect of the locking assembly 4 on the first support shaft 21 and the second support shaft 31.

[0063] Furthermore, refer to Figure 1 , Figure 2 and Figure 5 The support frame 1 is provided with a support member 5, and a locking rod 41 passes through the support member 5, and the support member 5 can slide relative to the support frame 1.

[0064] Since the support frame 1 is provided with the locking rod 41 passing through the support member 5, the locking rod 41 can be supported by the support member 5 to increase the stability of the locking rod 41, thereby increasing the stability of the first roller 2 and the second roller 3. Furthermore, since the support member 5 can slide relative to the support frame 1, the locking rod 41 can be supported at different positions by adjusting the support member 5, thereby increasing the flexibility of the support member 5.

[0065] Furthermore, refer to Figure 5 The support member 5 is provided with a through hole, the outer peripheral surface of the locking rod 41 is provided with a limiting groove 411, and the locking rod 41 passes through the through hole. The hole wall of the through hole is provided with a receiving cavity. The receiving cavity is provided with a limiting part 521 that can extend into the limiting groove 411 and an elastic part 522 for applying movement toward the limiting groove 411 to the limiting part 521.

[0066] Because the support member 5 is provided with a through hole, the outer peripheral surface of the locking rod 41 is provided with a limiting groove 411, and the locking rod 41 passes through the through hole. The hole wall of the through hole is provided with a receiving cavity. The receiving cavity is provided with a limiting part 521 that can extend into the limiting groove 411 and an elastic part 522 for applying movement towards the limiting groove 411 to the limiting part 521. Thus, on the one hand, the cooperation between the limiting part 521 and the limiting groove 411 can realize that the support member 5 moves with the locking rod 41, so as to realize the synchronous movement of the support frame 1 and the locking rod 41, thereby simplifying the user's operation steps. On the other hand, the cooperation between the limiting part 521 and the limiting groove 411 can also realize the limitation of the relative movement of the support member 5 and the locking rod 41, so as to increase the connection stability of the support member 5 and the locking rod 41, thereby ensuring the support effect of the support member 5 on the locking rod 41.

[0067] Specifically, after adjusting the laying roller assembly from the first position to the second position, the locking rod 41 is slid. At this time, the limiting part 521 abuts against the outer peripheral surface of the locking rod 41 under the action of the elastic part 522, so that the support member 5 moves synchronously with the locking rod 41. When the locking rod 41 moves to the position where the extension part 63 extends into the receiving groove 421, the sliding of the locking rod 41 is stopped, and the bolt pair 422 is installed. Then the support member 5 is slid, so that the support member 5 overcomes the friction between the limiting part 521 and the outer peripheral surface of the locking rod 41 and slides relative to the locking rod 41. When the limiting part 521 moves to the position where the limiting groove 411 is located, the limiting part 521 extends into the limiting groove 411 under the action of the elastic part 522, and the sliding of the support member 5 is stopped. The limiting part 521 and the limiting groove 411 are used to limit the support member 5.

[0068] This application does not specifically limit the structure of the limiting part 521 and the elastic part 522. Preferably, the limiting part 521 is a spherical structure and the elastic part 522 is a spring, so as to facilitate the release of the limiting part 521 from the limiting groove 411. In other embodiments, the limiting part 521 can also be other structures, such as a block structure; the elastic part 522 can also be other structures, such as an elastic sheet, an elastic column, etc.

[0069] The better one is to refer to Figure 2 Both ends of the support member 5 are provided with connecting sleeves 51 respectively sleeved on the outside of the two wing plates to realize the sliding connection between the support member 5 and the support frame 1. The support member 5 has a collar 52 at the middle position in the length direction, and the inside of the collar 52 forms a through hole.

[0070] Furthermore, refer to Figure 1 , Figure 2 and Figure 6The guide tube 11 has a waist-shaped groove 111 on its outer peripheral surface. The length direction of the waist-shaped groove 111 is parallel to the axial direction of the guide tube 11. The locking rod 41 has a linkage rod 412 that extends into the waist-shaped groove 111. An adjusting sleeve 112 is sleeved on the outside of the guide tube 11. The linkage rod 412 is fixedly connected to the adjusting sleeve 112 so that the adjusting sleeve 112 can slide, thereby causing the locking rod 41 to move under the action of the linkage rod 412. When the linkage rod 412 abuts against the groove wall of the waist-shaped groove 111 away from the support frame 1, the receiving groove 421 on the locking block 42 can accommodate the extension 63 in the first position. When the linkage rod 412 abuts against the groove wall of the waist-shaped groove 111 near the support frame 1, the receiving groove 421 on the locking block 42 can accommodate the extension 63 in the second position, so as to facilitate the locking of the first support shaft 21 and the second support shaft 31.
