Description

Technical Field

[0001] This invention relates to the field of brush roller technology, and more specifically to a brush roller structure for rotating and replacing brush strips. Background Technology

[0002] During the rust removal process of steel plates, brush rollers are needed to remove the rust from the surface. During the rust removal process, the brush strips are easily worn, affecting the cleaning effect. In order to maintain a good cleaning effect, the brush strips on the brush rollers need to be replaced at regular intervals.

[0003] In the applicant's previous patent application for a brush roller structure (publication number CN115476282), the brush roller includes a rotating shaft and a tube connected to the outside of the rotating shaft. A disc-shaped fixing seat is fixedly connected to one end of the rotating shaft. Multiple arc-shaped brush plates are evenly connected radially along the surface of the tube. The surface of the tube has connecting holes corresponding to each brush plate. Each brush plate has a connecting plate that mates with the connecting holes, and brush strips are provided on the surface of the brush plate. A limiting seat for fixing the brush plates is connected to the other end of the tube. The fixing seat has a locking mechanism that mates with each connecting plate, and the limiting seat has a fixing mechanism for fixing each connecting plate. The locking mechanism includes a slider, and a locking rod is fixedly connected to the slider. The end of the locking rod is provided with... The device features a slot and a locking block at one end of the connecting plate near the fixed base. The slot and locking block engage to connect. The fixing mechanism includes a rotating rod with a slidable locking seat for fixing the connecting plate. The locking seat engages with the connecting slot, allowing for quick brush plate replacement. A locking nut is threaded onto the rotating rod to limit and fix the locking seat. To disassemble, first remove the locking nut from the fixing mechanism to detach the locking seat from the extension plate. Then, manually slide the corresponding slider towards the center of the fixed base to separate the locking rod from the locking block. Next, move the brush plate towards the fixed base to disengage the extension plate from the limiting seat, allowing the brush plate to be removed and replaced. The operation is convenient.

[0004] Although the aforementioned patent enables partial replacement of the brush strips on the outside of the brush roller, it requires disassembling and assembling the locking nut, and also requires sliding the brush plate back and forth to complete the disassembly and assembly of the brush plate, which takes a long time and is quite cumbersome to operate. Summary of the Invention

[0005] To address the aforementioned technical shortcomings, the present invention aims to provide a brush roller structure for rotating and replacing brush strips. By setting fixed and movable connectors on the arc-shaped brush plate and the annular seat respectively, and by establishing a linkage structure between the two axially opposite movable connectors, when disassembling the arc-shaped brush plate, rotating the rotary drive tube sleeved on the roller shaft causes the drive unit on the rotary drive tube to act on the linkage structure, thereby separating the two axially opposite movable connectors from their corresponding fixed connectors. This allows for quick removal of the corresponding arc-shaped brush plate, simplifying the brush plate assembly and disassembly process and improving the efficiency of brush plate replacement.

[0006] The present invention adopts the following technical solution:

[0007] This invention provides a brush roller structure for rotating and replacing brush strips, including a roller shaft and a base tube coaxially mounted with the roller shaft; a plurality of arc-shaped brush plates for laying brush strips are arranged circumferentially on the outer wall of the base tube; a strip-shaped insertion part is provided on the inner wall of the arc-shaped brush plate; a strip-shaped insertion groove matching the strip-shaped insertion part is opened through the outer side of the base tube; the strip-shaped insertion part is inserted into the strip-shaped insertion groove; two end plates are sleeved on the roller shaft respectively located at both ends of the base tube, and an inwardly extending annular seat is provided on the inner end face of the end plate; a connecting assembly is provided between the two ends of the strip-shaped insertion part and the corresponding annular seat; the connecting assembly includes a fixed connecting member disposed on the strip-shaped insertion part and located in the base tube, and a movable connecting member disposed on the annular seat and corresponding to the fixed connecting member; a linkage structure is connected between each pair of axially opposite movable connecting members between the two annular seats; a rotary drive tube that can rotate along the roller shaft axis is sleeved on the roller shaft, and a drive part for acting on the linkage structure is provided on the rotary drive tube;

[0008] The brush roller structure has a working mode and a disassembly mode. In the working mode, the movable connecting parts cooperate with the fixed connecting parts to make the corresponding arc-shaped brush plates fit tightly against the base tube. When the brush roller structure switches to the disassembly mode, the rotary drive tube rotates and the drive unit acts on the corresponding linkage structure to link the two axially opposite movable connecting parts to move synchronously and separate from the corresponding fixed connecting parts, so that the corresponding arc-shaped brush plates can be removed from the base tube.

[0009] Preferably, the fixed connector is a fixed hook provided on the strip-shaped plug-in part, and the movable connector is a plurality of movable hooks evenly distributed on the annular seat in the circumferential direction; the movable hooks can swing on the annular seat and disengage from the fixed hooks, so that the corresponding arc-shaped brush plate can be separated from the base tube.

[0010] In the working mode, the movable hook and the fixed hook are engaged with each other so that the corresponding arc-shaped brush plate is tightly attached to the base tube. When the brush roller structure is switched to the disassembly mode, the rotating drive tube rotates and the drive unit acts on the corresponding linkage structure to link the two axially opposite movable hooks to swing synchronously and separate from the corresponding fixed hook, so that the corresponding arc-shaped brush plate can be removed from the base tube.

[0011] Preferably, the linkage structure is an elastic V-shaped rod connected between two axially opposite movable hooks, and the driving part is a top block set on the outer wall of the rotary drive tube; the rotary drive tube rotates, causing the top block to press and cause the corresponding elastic V-shaped rod to deform, so as to link the two axially opposite movable hooks to swing synchronously; when subjected to the action of the top block, the elastic V-shaped rod can convert its own elastic force into a linkage force to act on the movable hooks; when the top block separates from the elastic V-shaped rod, the elastic V-shaped rod can quickly return to its original position, which is simple and ingenious design.

[0012] Preferably, the elastic V-shaped rod includes support arms connected to two axially opposite movable hooks respectively, and the top block is positioned at the junction of the two support arms; the rotation drive tube rotates, causing the top block to press against the junction of the two support arms on the corresponding elastic V-shaped rod, and causing the elastic V-shaped rod to deform, so as to link the two axially opposite movable hooks to swing synchronously; the top block positioned at the junction of the two support arms can cause the two support arms to deform with the same amplitude, so that each pair of axially opposite movable hooks can stably disengage from the corresponding fixed hook.

[0013] Preferably, the annular seat has multiple rotating connecting seats evenly distributed along the circumference, and the corresponding movable hooks are rotatably mounted on the rotating connecting seats; the rotating connecting seats provide a corresponding mounting carrier for the movable hooks, so that the movable hooks can swing on the annular seat.

[0014] Preferably, it also includes an elastic element that acts on the movable hook. When the drive unit acts on the corresponding linkage structure, the movable hook swings and causes the elastic element to deform. When the drive unit separates from the linkage structure, the elastic element releases its elastic force and causes the movable hook to reset. The elastic element can provide a reset elastic force for the movable hook, so that in the working mode, the movable hook can form a snap-fit ​​with the fixed hook.

[0015] Preferably, the movable hook and the rotating connecting seat are rotatably connected by a rotating shaft, and the elastic element is a torsion spring sleeved on the rotating shaft and acting on the movable hook; the torsion spring can provide sufficient restoring force for the movable hook, while occupying little space and being easy to install.

[0016] Preferably, multiple first limiting blocks are evenly distributed circumferentially on the inner wall of the rotary drive tube; multiple first limiting grooves corresponding to the first limiting blocks are evenly distributed circumferentially on the outer wall of the roller shaft; the first limiting grooves extend axially, and the first limiting blocks are slidably connected within the first limiting grooves; an annular groove communicating with the multiple first limiting grooves is also formed on the outer wall of the roller shaft; when the brush roller structure is in working mode, the multiple first limiting blocks are locked in the corresponding first limiting grooves to restrict the rotation of the rotary drive tube; when the brush roller structure is switched to disassembly mode, external force pulls the rotary drive tube to slide on the roller shaft, so that... Multiple first limiting blocks slide from the first limiting groove into the annular groove, at which point the rotary drive tube can rotate axially. When the first limiting block and the first limiting groove are engaged, they can restrict the rotation of the rotary drive tube to prevent the movable hook and the fixed hook from accidentally disengaging in the working mode. When the first limiting block and the annular groove are engaged, it is equivalent to releasing the circumferential rotation restriction on the rotary drive tube, allowing the movable hook and the fixed hook to disengage freely in the disassembly mode. This design is simple and ingenious, and can realize the rotation control of the rotary drive tube, thereby allowing the brush roller structure to freely switch between the working mode and the disassembly mode.

[0017] Preferably, the end plate is relatively fixed to the base tube in the circumferential direction; multiple second limiting blocks are evenly distributed circumferentially on the outer wall of the rotary drive tube; multiple second limiting grooves are evenly distributed circumferentially on the inner side of the annular seat; the second limiting blocks are matched and installed in the second limiting grooves; when the brush roller structure is in the working mode, multiple second limiting blocks are locked in the corresponding second limiting grooves to restrict the rotation of the rotary drive tube; when the brush roller structure is switched to the disassembly mode, external force pulls the rotary drive tube to slide on the roller shaft, causing multiple second limiting blocks to disengage from the second limiting grooves, at which time the rotary drive tube can rotate axially; when the second limiting blocks and the second limiting grooves cooperate, they can restrict the rotation of the drive tube to prevent the movable hook and the fixed hook from accidentally disengaging in the working mode. When the second limiting block disengages from the second limiting groove, it is equivalent to releasing the circumferential rotation restriction on the drive tube, allowing the movable hook and the fixed hook to disengage freely in the disassembly mode. This design is simple and ingenious, and can realize the rotation control of the drive tube, thereby allowing the brush roller structure to freely switch between the working mode and the disassembly mode.

[0018] Preferably, one end of the rotary drive tube extends outward through the end plate and forms an exposed section, with multiple actuating grooves evenly distributed along the circumference of the exposed section; the actuating grooves facilitate manual or wrench rotation of the rotary drive tube by workers; when manually rotating the rotary drive tube, the actuating grooves can increase friction; when using a wrench, the actuating grooves can cooperate with the wrench to quickly rotate the rotary drive tube.

[0019] Preferably, the roller has a large-diameter section and a small-diameter section connected to each other, and a stepped surface is formed at the connection position of the large-diameter section and the small-diameter section. The rotary drive tube is sleeved on the small-diameter section. A magnet A is embedded in the end face of the rotary drive tube facing the stepped surface. A magnet B that is attracted to magnet A is embedded in the stepped surface. Through the mutual attraction between magnet A and magnet B, the rotary drive tube can be stably sleeved on the small-diameter section without sliding along the axial direction when no adjustment is required.

[0020] Preferably, the top block is located between two adjacent elastic V-shaped rods, and the top block has wedge-shaped surfaces on both sides facing the two elastic V-shaped rods; by setting the wedge-shaped surfaces, the top block can be more easily rotated to below the apex of the elastic V-shaped rod, which is convenient and saves effort.

[0021] Preferably, the linkage structure is an elastic telescopic assembly disposed between two axially opposite movable hooks. The elastic telescopic assembly includes two elastic telescopic rods respectively hinged to the two axially opposite movable hooks, and the driving part is a top block disposed on the outer wall of the rotary drive tube. The elastic telescopic rods are provided with linkage inclined surfaces corresponding to the position of the top block. When the rotary drive tube rotates, the top block presses against the linkage inclined surfaces and causes the elastic telescopic rods to elastically extend and retract, thereby linking the two axially opposite movable hooks to swing synchronously. When the top block acts on the linkage inclined surfaces, the elastic telescopic rods can form a linkage force on the movable hooks by their own extension and retraction process. When the top block separates from the linkage inclined surfaces, the elastic telescopic rods can quickly return to their original position. The design is simple and ingenious.

[0022] Preferably, the fixed connector is a snap-fit ​​seat provided on the strip-shaped plug-in part, and the snap-fit ​​seat is provided with snap-fit ​​holes. The movable connector is a plurality of movable plug-fit parts evenly distributed on the annular seat in the circumferential direction. The movable plug-fit parts are provided with snap-fit ​​pins for snapping with the snap-fit ​​holes. The movable plug-fit parts can swing on the annular seat and disengage the snap-fit ​​pins from the snap-fit ​​holes, so that the corresponding arc-shaped brush plate is disengaged from the base tube.

[0023] In the working mode, the pins of the brush roller structure are inserted into the pin holes so that the corresponding arc-shaped brush plates are tightly attached to the base tube. When the brush roller structure is switched to the disassembly mode, the rotating drive tube rotates and the drive unit acts on the corresponding linkage structure to link the two axially opposite movable plug-in parts to swing synchronously and make the corresponding pins disengage from the pin holes, so that the corresponding arc-shaped brush plates can be removed from the base tube.

[0024] The beneficial effects of this invention are as follows:

[0025] This invention provides movable and fixed connectors on the arc-shaped brush plate and the annular seat, respectively, and sets a linkage structure between the two axially opposite movable connectors. When the arc-shaped brush plate needs to be disassembled, simply rotate the rotary drive tube sleeved on the roller shaft and trigger the linkage structure to disengage the mating movable and fixed connectors, thereby allowing the strip-shaped insertion part on the arc-shaped brush plate to disengage from the strip-shaped insertion groove on the base tube. There is no need to disassemble the nut or slide the arc-shaped brush plate, making the operation simple and the disassembly and assembly efficiency high.

[0026] This invention features a first limiting groove evenly distributed circumferentially on the roller shaft, and an annular groove communicating with multiple first limiting grooves. A first limiting block is slidably connected to the first limiting groove on the inner wall of the rotary drive tube. When the first limiting block is in the first limiting groove, it restricts the rotary drive tube from rotating circumferentially, preventing accidental separation of the movable hook and the fixed hook, and ensuring the normal operation of the brush roller structure. When the first limiting block slides into the annular groove, the rotary drive tube can rotate normally and trigger the linkage structure to realize the replacement of the arc-shaped brush plate. The design is ingenious and achieves two goals at once. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] This invention has multiple embodiments, the specific implementation methods of which are as follows:

[0042] Example 1: Figure 1-10As shown, the present invention provides a brush roller structure for rotating and replacing brush strips, including a roller shaft 1 and a base tube 2 coaxially mounted with the roller shaft 1; a plurality of arc-shaped brush plates 3 for laying brush strips 32 are arranged circumferentially on the outer wall of the base tube 2; a strip-shaped insertion part 31 is provided on the inner wall of the arc-shaped brush plate 3; a strip-shaped insertion groove 21 matching the strip-shaped insertion part 31 is opened through the outer side of the base tube 2; the strip-shaped insertion part 31 is inserted into the strip-shaped insertion groove 21, so that the arc-shaped brush plate 3 is fixed in the axial direction; two end plates 4 are sleeved on the roller shaft 1, respectively located at both ends of the base tube 2, and the end plates 4 can play a certain role in shielding and sealing; an inwardly extending annular seat is provided on the inner end face of the end plate 4. 41. In this embodiment, the outer diameter of the annular seat 41 is smaller than the outer diameter of the end plate 4; a connecting component is provided between the two ends of the strip-shaped insertion part 31 and the corresponding annular seat 41. The connecting component includes a fixed connector provided on the strip-shaped insertion part 31 and inside the base tube 2, and a movable connector provided on the annular seat 41 and corresponding to the fixed connector. The two axially opposite movable connectors can be simultaneously disengaged or engaged with the corresponding fixed connectors. Between the two annular seats 41, a linkage structure is connected between each pair of axially opposite movable connectors. A rotary drive tube 71 that can rotate along the axis of the roller shaft 1 is sleeved on the roller shaft 1. The rotary drive tube 71 is provided with a drive part for acting the linkage structure.

[0043] The brush roller structure has a working mode and a disassembly mode. In the working mode, the movable connecting parts cooperate with the fixed connecting parts to make the corresponding arc-shaped brush plate 3 fit tightly against the base tube 2. At this time, the brush roller structure can normally brush the steel plate. When the brush roller structure switches to the disassembly mode, the rotating drive tube 71 rotates and the drive part acts on the corresponding linkage structure to link the two axially opposite movable connecting parts to move synchronously and separate from the corresponding fixed connecting parts. At this time, it is only necessary to pull the strip-shaped insertion part 31 out of the strip-shaped insertion groove 21 to remove the corresponding arc-shaped brush plate 3 from the base tube 2.

[0044] Furthermore, in this embodiment, the connecting component is a hook-type component. Specifically, the fixed connector is a fixed hook 311 provided on the strip-shaped insertion part 31, and the movable connector is a plurality of movable hooks 51 evenly distributed circumferentially on the annular seat 41. A plurality of rotating connecting seats 52 are evenly distributed circumferentially on the annular seat 41, and the corresponding movable hooks 51 are rotatably mounted on the rotating connecting seats 52. The rotating connecting seats 52 provide a corresponding mounting carrier for the movable hooks 51. The movable hooks 51 can swing on the annular seat 41 and disengage from the fixed hooks 311, so that the corresponding arc-shaped brush plate 3 is disengaged from the base tube 2.

[0045] In the working mode, the movable hook 51 and the fixed hook 311 are engaged with each other so that the corresponding arc-shaped brush plate 3 is tightly attached to the base tube 2. When the brush roller structure is switched to the disassembly mode, the rotary drive tube 71 rotates and the drive unit acts on the corresponding linkage structure to link the two axially opposite movable hooks 51 to swing synchronously and separate from the corresponding fixed hook 311, so that the corresponding arc-shaped brush plate 3 can be removed from the base tube 2.

[0046] Furthermore, the linkage structure requires the movable hooks 51 to swing synchronously to achieve engagement or disengagement with the fixed hooks 311. Therefore, in this embodiment, the linkage structure is an elastic V-shaped rod 6 connected between two axially opposite movable hooks 51, and the driving part is a top block 72 disposed on the outer wall of the rotary drive tube 71. The rotary drive tube 71 rotates, causing the top block 72 to press and cause the corresponding elastic V-shaped rod 6 to deform, thereby linking the two axially opposite movable hooks 51 to swing synchronously. When acted upon by the top block 72, the elastic V-shaped rod 6 can convert its own elastic force into a driving force to act on the movable hooks 51. When the top block 72 separates from the elastic V-shaped rod 6, the elastic V-shaped rod 6 can quickly reset, allowing the movable hooks 51 to engage with the fixed hooks 311 on the new arc-shaped brush plate 3, thereby preventing the arc-shaped brush plate 3 from detaching.

[0047] Furthermore, the elastic V-shaped rod 6 includes support arms connected to two axially opposite movable hooks 51 respectively. In order for the two axially opposite movable hooks 51 to disengage from the fixed hooks 311 synchronously, the linkage force on the two movable hooks 51 should be the same, so as to produce the same swing amplitude. Therefore, in this embodiment, the top block 72 corresponds to the junction of the two support arms. The rotation drive tube 71 rotates, causing the top block 72 to press against the junction of the two support arms on the corresponding elastic V-shaped rod 6, and causing the elastic V-shaped rod 6 to deform, so as to link the two axially opposite movable hooks 51 to swing synchronously. The top block 72 can cause the two support arms to deform with the same amplitude, so that each pair of axially opposite movable hooks 51 can stably disengage from the corresponding fixed hooks 311.

[0048] Furthermore, to enable the movable hook 51 to quickly reset, the brush roller structure also includes an elastic element. The elastic element acts on the movable hook 51. When the drive unit acts on the corresponding linkage structure, the movable hook 51 swings and causes the elastic element to deform. When the drive unit separates from the linkage structure, the elastic element releases its elastic force and causes the movable hook 51 to reset. The elastic element can provide a reset elastic force for the movable hook 51, so that in the working mode, the movable hook 51 can form a snap-fit ​​engagement with the fixed hook 311. Specifically, the movable hook 51 is rotatably connected to the rotating connecting seat 52 through a rotating shaft. The elastic element is a torsion spring 53 sleeved on the rotating shaft and acting on the movable hook 51. The torsion spring 53 can provide sufficient reset elastic force for the movable hook 51, while occupying little space and being easy to install.

[0049] Furthermore, such as Figure 7-9 As shown, to facilitate control of the rotary drive tube 71, multiple first limiting blocks 712 are evenly distributed circumferentially on the inner wall of the rotary drive tube 71; multiple first limiting grooves 12 corresponding to the first limiting blocks 712 are evenly distributed circumferentially on the outer wall of the roller shaft 1; the first limiting grooves 12 extend axially, and the first limiting blocks 712 are slidably connected within the first limiting grooves 12; an annular groove 13 communicating with the multiple first limiting grooves 12 is also formed on the outer wall of the roller shaft 1; when the brush roller structure is in working mode, the multiple first limiting blocks 712 are locked in the corresponding first limiting grooves 12 to restrict the rotation of the rotary drive tube 71; when the brush roller structure is switched to disassembly mode, external force pulls the rotary drive tube 71 to slide on the roller shaft 1, causing the multiple first limiting blocks 712 to... The rotary drive tube 71 slides from the first limiting groove 12 into the annular groove 13, at which point it can rotate axially. Specifically, the state of the rotary drive tube 71 is different in the working mode and the disassembly mode. When the first limiting block 712 and the first limiting groove 12 cooperate, they can restrict the rotation of the rotary drive tube 71 to prevent the movable hook 51 from accidentally disengaging from the fixed hook 311 in the working mode. When the first limiting block 712 and the annular groove 13 cooperate, it is equivalent to releasing the circumferential rotation restriction on the rotary drive tube 71, allowing the movable hook 51 to freely disengage from the fixed hook 311 in the disassembly mode. This design is simple and ingenious, and can realize the rotation control of the rotary drive tube 71, thereby allowing the brush roller structure to freely switch between the working mode and the disassembly mode.

[0050] Furthermore, the end plate 4 is relatively fixed to the base tube 2 in the circumferential direction, and the end plate 4 is usually connected to both ends of the base tube 2 by screws; multiple second limiting blocks 711 are evenly distributed circumferentially on the outer wall of the rotary drive tube 71; multiple second limiting grooves 411 are evenly distributed circumferentially on the inner side of the annular seat 41; the second limiting blocks 711 are matched and installed in the second limiting grooves 411; when the brush roller structure is in working mode, multiple second limiting blocks 711 are stuck in the corresponding second limiting grooves 411 to restrict the rotation of the rotary drive tube 71; when the brush roller structure is switched to disassembly mode, external force pulls the rotary drive tube 71 to slide on the roller shaft 1, causing multiple second limiting blocks 711 to disengage from the first roller shaft 1. The second limiting groove 411 allows the rotary drive tube 71 to rotate axially. Specifically, in both working and disassembly modes, the second limiting block 711 and the second limiting groove 411 work together to restrict the rotation of the rotary drive tube 71, preventing the movable hook 51 from accidentally disengaging from the fixed hook 311 in working mode. When the second limiting block 711 disengages from the second limiting groove 411, it effectively releases the circumferential rotation restriction on the rotary drive tube 71, allowing the movable hook 51 to freely disengage from the fixed hook 311 in disassembly mode. This design is simple and ingenious, enabling another layer of control over the rotary drive tube 71 and allowing the brush roller structure to freely switch between working and disassembly modes.

[0051] Furthermore, to facilitate the worker's rotation of the rotary drive tube 71 when the arc-shaped brush plate 3 needs to be replaced, one end of the rotary drive tube 71 extends outward through the end plate 4 and forms an exposed section. Multiple actuating grooves 713 are evenly distributed along the circumference of the exposed section. The actuating grooves 713 facilitate the worker's manual or wrench rotation of the rotary drive tube 71. When manually rotating the rotary drive tube 71, the actuating grooves 713 can increase the friction. When using a wrench, the actuating grooves 713 can cooperate with the wrench to quickly rotate the rotary drive tube 71.

[0052] Furthermore, the rotary drive tube 71 is fitted onto the roller 1 as follows: the roller 1 has a large-diameter section and a small-diameter section 11 connected to each other, and a stepped surface is formed at the connection position of the large-diameter section and the small-diameter section 11. The rotary drive tube 71 is fitted onto the small-diameter section 11. In order to prevent the rotary drive tube 71 from moving axially in the working mode, a magnet A714 is embedded in the end face facing the stepped surface. A magnet B111 is embedded in the stepped surface and attracts the magnet A714. Through the mutual attraction between the magnet A and the magnet B, the rotary drive tube 71 can be stably fitted onto the small-diameter section when no adjustment is required.

[0053] Furthermore, the top block 72 is located between two adjacent elastic V-shaped rods 6. In order to press the elastic V-shaped rods 6 more smoothly, the top block 72 is provided with wedge-shaped surfaces 721 on both sides facing the two elastic V-shaped rods 6. The wedge-shaped surfaces 721 make it easier for the top block 72 to rotate to the junction of the two support arms, which is convenient and labor-saving.

[0054] Example 2: This example differs from the above examples in that the linkage structure is different, such as... Figure 11 As shown, in this embodiment, the linkage structure is an elastic telescopic assembly disposed between two axially opposite movable hooks 51. The elastic telescopic assembly includes two elastic telescopic rods 8 respectively hinged to the two axially opposite movable hooks 51. The elastic telescopic rods are provided with linkage inclined surfaces 81 corresponding to the position of the top block 72. The rotation drive tube 71 rotates, causing the top block 72 to press against the linkage inclined surfaces 81 and causing the elastic telescopic rods 8 to elastically extend and retract, thereby linking the two axially opposite movable hooks 51 to swing synchronously. Specifically, multiple supports 4 are evenly distributed circumferentially on the annular seat 4. 2. A guide hole is provided on the support 42, and the corresponding elastic telescopic rod 8 passes through the guide hole. The elastic telescopic rod 8 has an annular protrusion 82. A compression spring 9 is provided between the annular protrusion 82 and the support 42 to provide the elastic telescopic rod 8 with the telescopic force. When the top block 72 acts on the linkage inclined surface 81, the elastic telescopic rod 8 can form a linkage force on the movable hook 51 by its own telescopic process. When the top block 72 separates from the linkage inclined surface 81, the elastic telescopic rod 8 can quickly reset by relying on the elastic force stored after the compression spring 9 is deformed; so as to achieve the same linkage effect as in the above embodiment.

[0055] Example 3: This example differs from the previous examples in that the connecting component is a plug-in component, such as... Figure 12 As shown, the fixed connector is a snap-fit ​​seat 33 provided on the strip-shaped plug-in part 31, and the snap-fit ​​seat 33 is provided with a snap-fit ​​hole 34. The movable connector is a plurality of movable plug-in parts 54 evenly distributed in the circumferential direction on the annular seat 41. The movable plug-in parts 54 are provided with snap-fit ​​pins 55 for snapping into the snap-fit ​​hole 34.
