Description

Technical Field

[0001] This application relates to the field of high-altitude wall spraying technology, specifically to an automatic spraying system for high-altitude exterior walls. Background Technology

[0002] Currently, high-altitude exterior wall spraying construction has achieved unmanned spraying, that is, the use of intelligent spraying equipment to automatically spray high-altitude exterior walls. The intelligent spraying equipment uses a suspended platform as the installation platform, and the platform is raised and lowered by a lifting device above, thereby achieving top-down or bottom-up spraying of the wall surface.

[0003] For some wall painting operations with protrusions, the protrusions usually do not need to be painted. Since the distance between the suspended platform and the wall needs to be maintained within a certain safe range during the painting process, a large protrusion can obstruct the platform. That is, the platform needs to avoid the protrusion during ascent or descent to achieve continuous painting. Chinese utility model patent CN219509136U discloses a wall-supported obstacle-crossing device for an aerial work platform. It mainly achieves obstacle crossing through the interaction of a covering belt and a protrusion. However, when the covering belt and the protrusion slide relative to each other, it causes wear on the covering belt and / or the protrusion. Furthermore, when the covering belt and the protrusion slide relative to each other, the friction causes the entire suspended platform to have a significant risk of shaking, posing a safety hazard. Summary of the Invention

[0004] This application provides an automatic spraying system for high-altitude exterior walls. By setting up an obstacle-crossing device, the suspended platform can cross obstacles in a swinging motion mode. By setting up an auxiliary balancing component on the suspended platform, the overall stability of the platform during obstacle crossing is further ensured. The system does not slide relative to the protrusions during obstacle crossing, thus avoiding the problems of mutual wear and vibration risk in existing obstacle crossing modes.

[0005] This application is achieved through the following technical solution: An automated spraying system for high-altitude exterior walls includes: The suspended platform has a movable opening; A lifting device, which is connected to the suspended basket via slings, is used for installation on the rooftop; A spraying device, which is mounted on a suspended platform, is used for spraying wall surfaces; An obstacle-crossing device, one end of which is rotatably connected to the suspended basket and located in the movable opening along its length, and the other end of which has a rotatable clamping assembly. When the obstacle-crossing device rotates on the suspended basket, it can clamp the protrusion on the wall through the clamping assembly to drive the suspended basket to swing around the protrusion in the vertical plane. An auxiliary balancing assembly is connected to the suspended platform and has a movable counterweight. In operation, when the obstacle-crossing device rotates in the movable opening, the counterweight actuates to make the center of gravity of the auxiliary balancing component and the obstacle-crossing device collinear with the center of gravity of the basket and the spraying device in the vertical direction.

[0006] The automatic spraying system for high-altitude exterior walls provided in this application can clamp protrusions on the wall surface through an obstacle-crossing device.

During the obstacle crossing process, there is no relative sliding between the suspended basket and the protrusion, and there are no problems of mutual wear and vibration. At the same time as the obstacle-crossing device moves, the counterweight in the auxiliary balancing component moves accordingly to stabilize the center of gravity of the auxiliary balancing component and the obstacle-crossing device, ensuring that the suspension cable is under balanced force before the basket swings, preventing large-amplitude vibrations of the basket during the swing, and thus ensuring the overall stability of the spraying device during the obstacle crossing process.

During the obstacle crossing process, there is no relative sliding between the suspended basket and the protrusion, and there are no problems of mutual wear and vibration. At the same time as the obstacle-crossing device moves, the counterweight in the auxiliary balancing component moves accordingly to stabilize the center of gravity of the auxiliary balancing component and the obstacle-crossing device, ensuring that the suspension cable is under balanced force before the basket swings, preventing large-amplitude vibrations of the basket during the swing, and thus ensuring the overall stability of the spraying device during the obstacle crossing process.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this application are only for explaining this application and are not intended to limit this application.

[0020] like Figures 1-10 As shown in the figure, this application provides an automatic spraying system for high-altitude exterior walls. The automatic spraying system for high-altitude exterior walls includes a suspended platform 20, lifting equipment, spraying device 30, obstacle crossing device, and auxiliary balancing component 40.

[0021] The suspended platform 20 can be configured as a cuboid frame structure, and the suspended platform 20 has a movable opening formed from one side of the suspended platform 20.

[0022] The lifting equipment (not shown in the figure) is connected to the suspended platform 20 via slings. The lifting equipment can be configured as an existing winch. There are at least four slings, which are connected to the four corner points of the suspended platform 20 respectively. The lifting equipment is used to install on the roof. By controlling the extension and retraction of the slings through the lifting equipment, the suspended platform 20 can be raised or lowered in the height direction.

[0023] The spraying device 30 is installed on the suspended platform 20. The spraying device 30 can be an existing automatic spraying device 30. The spraying device 30 has a spray gun and is used to spray the wall surface through the spray gun.

[0024] One end of the obstacle crossing device is rotatably connected to the basket 20 and located in the movable opening. This end is equipped with a power source, meaning that under the drive of the power source, the obstacle crossing device can rotate around this end on the basket 20. The other end of the obstacle crossing device has a rotatable clamping assembly 102. When the obstacle crossing device rotates on the basket 20, it can clamp the protrusion 50 on the wall through the clamping assembly 102 to drive the basket 20 to swing around the protrusion 50 in the vertical plane.

[0025] The auxiliary balancing component 40 is connected to the suspended platform 20. The auxiliary balancing component 40 and the obstacle crossing device can be located on opposite sides of the suspended platform 20. The auxiliary balancing component 40 has a movable counterweight. In specific implementation, the auxiliary balancing component 40 can include a counterweight rod and a counterweight block. One end of the counterweight rod is rotatably connected to the suspended platform 20 and is equipped with a power source. That is, under the drive of the power source, the counterweight rod can rotate on the suspended platform 20. In other words, the aforementioned movable counterweight means that the counterweight can move relative to the suspended platform 20. The counterweight block is connected to the other end of the counterweight rod. Through the drive of the counterweight rod, the counterweight block can be located at different positions in the vertical plane, thereby realizing the adjustment of the center of gravity position of the auxiliary balancing component 40 and the obstacle crossing device.

[0026] In operation, when the obstacle-crossing device rotates within the movable opening, the counterweight actuates to align the center of gravity of the auxiliary balancing component 40 and the obstacle-crossing device with the center of gravity of the suspended platform 20 and the spraying device 30 in the vertical direction. In other words, the force exerted on the suspended platform 20 by the gravity of the obstacle-crossing device is relatively balanced with the force exerted on the suspended platform 20 by the gravity of the auxiliary balancing component 40. Specifically, the center of gravity of the obstacle-crossing device and the center of gravity of the auxiliary balancing component 40 are centrally symmetrical about the vertical direction where the centers of gravity of the suspended platform 20 and the spraying device 30 are located. In practice, at least two obstacle-crossing devices are typically used; therefore, the auxiliary balancing component 40 and the obstacle-crossing device are usually positioned symmetrically about the centerline in the width direction of the suspended platform 20.

[0027] The automatic spraying system for high-altitude exterior walls provided in this application can clamp the protrusions 50 on the wall surface through the obstacle crossing device. When the clamping component 102 in the obstacle crossing device rotates, the obstacle crossing device can drive the suspended basket 20 to swing in the vertical plane, thereby crossing the wall protrusions 50. During the obstacle crossing process, there is no relative sliding between the suspended basket 20 and the protrusion 50, and there are no problems of mutual wear and vibration. At the same time as the obstacle crossing device moves, the counterweight in the auxiliary balancing component 40 moves accordingly to stabilize the center of gravity of the auxiliary balancing component 40 and the obstacle crossing device, ensuring that the suspension cable of the suspended basket 20 is under balanced force before swinging, preventing large-amplitude vibration of the suspended basket 20 during the swing, and thus ensuring the overall stability of the spraying device 30 during the obstacle crossing process.

[0028] In some optional embodiments, slide rails are provided on both sides of the movable notch, and the spraying device 30 has multiple nozzles, each of which is slidably connected to a slide rail. That is, the nozzles can slide on the slide rails to spray different parts of the wall. In actual implementation, a gear drive mechanism can be configured on each nozzle, and a rack can be installed on the slide rail. The interaction between the gear drive mechanism and the rack enables the nozzle to slide on the slide rail. The nozzles can also be equipped with telescopic components, such as telescopic cylinders. When the nozzle moves to the end of the slide rail, i.e., the position of the movable notch, the telescopic component can drive the nozzle to move so that the nozzle aligns with the position of the movable notch, thereby spraying the wall surface corresponding to the movable notch.

[0029] In some alternative embodiments, the slide rail is connected to the suspended platform 20 via a height adjustment component. The suspended platform 20 itself has a height; if the position of the slide rail on the suspended platform 20 is fixed, it is difficult to achieve overall wall spraying. For example, if the slide rail is fixed at the top of the suspended platform 20, when the suspended platform 20 descends to near the protrusion 50, the wall surface corresponding to the suspended platform 20 cannot be sprayed by the nozzles. Furthermore, during the process of the suspended platform 20 crossing obstacles, it swings away from the wall, at which point the nozzles also cannot spray the wall. In other words, multiple discontinuous areas will appear on the wall surface during the entire spraying process. The height adjustment component can adjust the height of the slide rail, meaning the slide rail can be positioned at different locations on the suspended platform 20. When the suspended platform 20 is near the protrusion 50, by adjusting the height of the slide rail, for example, moving the slide rail from the top of the suspended platform 20 to the bottom of the suspended platform 20, spraying can be performed on the wall surface corresponding to the suspended platform 20.

[0030] In some optional embodiments, the obstacle-crossing device includes a swing arm 101; the swing arm 101 is telescopic, and one end of the swing arm 101 is connected to a swing drive source, which is used to connect to the suspended platform 20. The swing drive source can be configured as a motor, and one end of the swing arm 101 is fixedly connected to the output shaft of the motor. That is, the swing arm 101 can rotate around one end under the drive of the motor. The motor is used to be fixedly connected to the suspended platform 20, so that the swing arm 101 swings relative to the suspended platform 20 under the drive of the motor. The clamping assembly 102 is rotatably connected to the other end of the swing arm 101, so that the clamping assembly 102 and the swing arm 101 can rotate relative to each other. That is, the swing arm 101 can rotate around the clamping assembly 102 or the clamping assembly 102 can rotate around the swing arm 101. The clamping assembly 102 is used to clamp the protrusion 50 on the wall.

[0031] The number of swing rods 101 can be configured to be multiple, so that multiple clamping components 102 can clamp multiple protrusions to ensure the stability of the suspended platform 20. For example, the swing rods 101 can be detachably connected to the suspended platform 20 through a swing drive source. In actual implementation, the layout of protrusions on the wall usually follows a certain pattern. Based on the layout of protrusions on the wall, the swing rods 101 can be connected to the appropriate positions on the suspended platform 20. If it is necessary to spray other wall surfaces with significant differences, the connection positions of the swing rods 101 can be adjusted accordingly.

[0032] After the swing rod 101 is connected to the suspended platform 20 via a swing drive source, the swing rod 101 is inclined relative to the vertical direction. The clamping assembly 102 is located at the bottom of the suspended platform 20, and from a vertical perspective, the clamping assembly 102 has a gap with the protrusion. The clamping assembly 102 is further away from the wall than the swing drive source. During the descent of the suspended platform 20, when the suspended platform 20 approaches the protrusion, the swing drive source drives the swing rod 101 to swing. While swinging, the swing rod 101 retracts itself. When the swing rod 101 is in a vertical state, when the swing rod 101 continues to swing, it extends itself, so that the clamping assembly 102 can translate relative to the suspended platform 20 to approach the protrusion. That is, the clamping assembly 102 gradually approaches the protrusion in the horizontal direction. When the relative position of the clamping assembly 102 and the protrusion is in place, the clamping assembly 102 clamps the protrusion. The holding assembly 102 remains relatively fixed to the protrusion. The swing drive source continues to drive the swing rod 101 to swing. Since the holding assembly 102 is fixed, the swing rod 101 essentially rotates on the holding assembly 102, causing the basket 20 to swing. In other words, the basket 20 gradually moves away from the protrusion horizontally. While the swing drive source is driving the swing rod 101, the swing rod 101 continuously extends, keeping the basket 20 horizontally away from the protrusion while maintaining a constant vertical height. During the translation of the basket 20... The lifting equipment above performs a corresponding line-laying operation to ensure the overall stability of the suspended platform 20 and prevent it from tilting. When the suspended platform 20 moves to a position where the horizontal distance between it and the protrusion is greater than the minimum length of the swing rod 101, the swing rod 101 is driven to swing, and it retracts. The lifting equipment above continues the line-laying operation, allowing the suspended platform 20 to move vertically. When the swing rod 101 is horizontal, it is driven to swing while simultaneously extending. Once the suspended platform 20 is vertically offset from the protrusion, the swing rod 101 continues to swing, retracting itself. This causes the suspended platform 20 to gradually approach the protrusion horizontally. When the swing rod 101 is vertical, it extends until the suspended platform 20 is below the protrusion. Without the clamping action of the clamping component 102, the suspended platform 20 will not wobble. The clamping component 102 is released from its grip on the protrusion. The swing of the swing rod 101 and its extension and retraction move the clamping component 102 away from the protrusion, allowing the suspended platform 20 to be lowered smoothly. After the suspended platform 20 has crossed the obstacle and been lowered to a certain height, the swing of the swing rod 101 and its extension and retraction move the clamping component 102 back to its original position below the suspended platform 20.

[0033] The obstacle-crossing device for a suspended platform 20 provided in this application embodiment allows the suspended platform 20 to translate horizontally or vertically via a swing arm 101 through swinging and its own extension and retraction. This results in a smaller overall swing amplitude of the suspended platform 20 relative to the wall, reducing the need for large-scale movement, lowering the control requirements for the overhead lifting equipment, and reducing the risk of system malfunctions. Simultaneously, the swing arm 101 also allows the clamping component 102 to translate, requiring less space as it approaches and clamps the protrusion. In other words, no additional space needs to be reserved between the suspended platform 20 and the protrusion. Compared to existing obstacle-crossing devices, the obstacle-crossing device for a suspended platform 20 provided in this application embodiment does not slip relative to the protrusion during obstacle crossing. Neither the protrusion nor the obstacle-crossing device suffers wear, and the suspended platform 20 does not vibrate due to relative slippage, reducing safety hazards. Meanwhile, compared with some existing obstacle-crossing strategies, the obstacle-crossing device for the suspended platform 20 provided in this application embodiment does not come into contact with the wall during the obstacle-crossing process. In the multi-layer spraying operation environment, it will not damage the coating already sprayed on the wall, thus ensuring the spraying efficiency of the wall.

[0034] In this embodiment, the swing arm 101 in the obstacle-crossing device is located within the movable opening, while the clamping assembly 102 is located below the basket 20. That is, the clamping assembly 102 does not occupy the internal space of the basket 20, allowing the width of the movable opening to be set as small as possible, just enough to facilitate the swing of the swing arm 101. When the nozzle moves to the movable opening, the stroke requirement for the telescopic component is lower, resulting in a smaller telescopic component size and less space occupation.

[0035] In some optional embodiments, the clamping assembly 102 may include a support plate 1021, a first clamping plate 1022, a second clamping plate 1023, and a clamping drive assembly 1024; the support plate 1021 is rotatably connected to the swing rod 101, and the support plate 1021 may be configured as a square plate. The swing rod 101 is rotatably connected to the support plate 1021, wherein the swing rod 101 is located on one side of the support plate 1021 so that the support plate 1021 can rotate 360 ​​degrees around the swing rod 101. For example, it may be... A connecting shaft is rotatably mounted on the surface of the support plate 1021, with its axis parallel to the surface of the support plate 1021. The connecting shaft is connected to the swing rod 101, allowing the swing rod 101 to rotate on the support plate 1021. Alternatively, the connecting shaft can extend from the side of the support plate 1021. The first clamping plate 1022 can be constructed as a rectangular plate and is perpendicularly fixed to the support plate 1021. The second clamping plate 1023 is connected to the second clamping plate 1021. The first clamping plate 1022 and the second clamping plate 1023 are arranged in parallel and slidably connected to the support plate 1021, forming a clamping gap for clamping the protrusion 50; the clamping drive assembly 1024 is connected to the support plate 1021 and the second clamping plate 1023 to drive the second clamping plate 1023 to move closer to / away from the first clamping plate 1022; wherein, an angle holding assembly 1025 is provided between the swing rod 101 and the support plate 1021, so that the angle holding assembly 1025 can... This ensures that the support plate 1021 remains parallel to the wall, preventing it from swaying during movement. In other words, the first clamping plate 1022 and the second clamping plate 1023 can maintain a perpendicular relationship with the wall. This allows the protrusion to enter the clamping gap during the translation of the clamping assembly 102, enabling the first clamping plate 1022 and the second clamping plate 1023 to quickly clamp the protrusion without requiring attitude detection and adjustment of the clamping assembly 102, thus improving obstacle crossing efficiency.

[0036] In some alternative embodiments, the angle holding assembly 1025 is configured as a rotary motor, the output shaft of which is connected to the swing arm 101. Thus, the angle of the support plate 1021 can be adjusted by the rotary motor. In practice, the rotational speed of the rotary motor and the swing drive source is coupled to ensure that the support plate 1021 remains parallel to the wall surface at all times.

[0037] In some optional embodiments, the angle holding assembly 1025 further includes a limiting ring 10251, a limiting connecting rod 10252, a limiting mounting plate 10253, and a ratchet 10254; the limiting ring 10251 has ratchet teeth 10255 disposed on its inner wall, and the limiting ring 10251 is fixedly connected to the support plate 1021; the limiting connecting rod 10252 is coaxially arranged with the limiting ring 10251, and its two ends are respectively connected to the swing rod 101 and the rotating motor, and the limiting connecting rod 10252 is rotatably connected to the support plate 1021, for example, two mounting blocks can be provided on the support plate 1021 to... The limiting connecting rod 10252 is sequentially movably mounted on two mounting blocks. Bearings can be configured between the mounting blocks and the limiting connecting rod 10252 to ensure smooth rotation. The swing rod 101 and the rotating motor are located on both sides of the limiting ring 10251, respectively. The limiting mounting plate 10253 is coaxially connected to the limiting connecting rod 10252 and is located inside the limiting ring 10251. The pawl 10254 is slidably mounted on the limiting mounting plate 10253. A telescopic component is configured between the pawl 10254 and the limiting mounting plate 10253 to drive the pawl 10254 to engage or disengage with the ratchet 10255.

[0038] In this embodiment, the ratchet 10255 and the pawl 10254 work together to restrict the connecting rod 10252 to rotate in one direction. This prevents the bearing plate 1021 from rotating backward as the clamping assembly 102 approaches the protrusion, thus avoiding the bearing plate 1021 from shaking due to backward rotation when the rotating motor malfunctions. In particular, when the bearing plate 1021 is close to the protrusion, it can prevent the bearing plate 1021 from colliding with the protrusion due to shaking.

[0039] In some optional embodiments, the telescopic assembly includes an elastic telescopic member 10256 and an electromagnet 10257; the elastic telescopic member 10256 is connected to the pawl 10254 and the limiting mounting plate 10253 respectively so that the pawl 10254 has a tendency to move closer to the ratchet 10255, that is, the pawl 10254 can engage with the ratchet 10255 under the elastic force of the elastic telescopic member 10256 alone; the electromagnet 10257 is connected to the limiting mounting plate 10253, and the electromagnet 10257 and the pawl 10254 are arranged at intervals, and the electromagnet 10257 is used to attract the pawl 10254 so that the pawl 10254 moves away from the ratchet 10255.

[0040] In this embodiment, the elastic telescopic member 10256 can make the ratchet 10255 and the pawl 10254 engage without the action of external force, thus preventing the bearing plate 1021 from rotating backward; that is, without the intervention of the control system, the bearing plate 1021 is in a unidirectional rotation state, and the system has good reliability.

[0041] In some optional embodiments, the clamping drive assembly 1024 includes a transmission gear 10241, a drive gear 10242, a transmission connecting rod 10243, and a transmission block 10244; the transmission gear 10241 is rotatably connected to the support plate 1021; the drive gear 10242 meshes with the transmission gear 10241 and is rotatably connected to the support plate 1021, wherein the diameter of the transmission gear 10241 is larger than the diameter of the drive gear 10242, and the drive gear 10242 is equipped with a clamping drive source, wherein the tooth surface of the transmission gear 10241 is flush with the plate surface of the support plate 1021. The surfaces are parallel; one end of the transmission link 10243 is rotatably connected to the transmission gear 10241, and the transmission link 10243 is eccentrically arranged with the axis of the transmission gear 10241; the transmission block 10244 is rotatably connected to the other end of the transmission link 10243 and is slidably connected to the support plate 1021; wherein, the second clamping plate 1023 is connected to the transmission block 10244 to form a sliding connection with the support plate 1021, thereby driving the gear 10242 to rotate and drive the transmission link 10243 to swing, and the transmission link 10243 then drives the slider to slide on the support plate 1021.

[0042] In this embodiment, the meshing of the transmission gear 10241 and the drive gear 10242 drives the transmission block 10244 to move, causing the second clamping plate 1023 to slide on the support plate 1021. After providing a certain driving power to the drive gear 10242, the transmission gear 10241 can obtain a large torque. That is to say, by configuring a smaller-sized drive source for the drive gear 10242, the second clamping plate 1023 and the first clamping plate 1022 can have a large clamping force. At the same time, the diameter of the drive gear 10242 is smaller than that of the transmission gear 10241. It can finely adjust the clamping force to ensure the clamping stability of the first clamping plate 1022 and the second clamping plate 1023; and the smaller size of the drive source has a smaller volume, which can reduce the space occupied below the basket 20; at the same time, the transmission structure of the drive gear 10242 and the transmission gear 10241 has a smaller vertical space occupation compared with the direct use of the linear drive structure. That is to say, the vertical space occupation of the clamping assembly 102 depends on the width / length of the bearing plate 1021. After the basket 20 crosses the obstacle, the vertical distance between it and the protrusion can be smaller.

[0043] In some optional embodiments, an elastic reset component is disposed between the transmission block 10244 and the support plate 1021 to give the second clamping plate 1023 a tendency to move away from the first clamping plate 1022. Specifically, an elongated hole can be provided on the support plate 1021, the slider is located in the elongated hole and slides in cooperation with the hole wall, one end of the elastic reset component is connected to the slider, and the other end is connected to the hole wall of the elongated hole. With the setting of the elastic reset component, after the first clamping plate 1022 and the second clamping plate 1023 release the clamping of the protrusion, the second clamping plate 1023 can move away from the first clamping plate 1022 more quickly on its own. That is to say, when the clamping component 102 releases the clamping of the protrusion, the power supply to the clamping drive source can be stopped, and the basket 20 can be lowered immediately to spray the wall below the protrusion, thereby improving the overall efficiency of the spraying construction.

[0044] In some optional embodiments, the swing arm 101 may include a fixed arm 1011, a telescopic drive assembly 1013, and a movable arm 1012; one end of the fixed arm 1011 is rotatably connected to the basket 20, that is, the end is rotatably connected to the basket 20 through a swing drive source, and the fixed arm 1011 has a first mounting groove 10111 and a second mounting groove 10112; the telescopic drive assembly 1013 is disposed in the first mounting groove 10111; the movable arm 1012 is disposed in the second mounting groove 10112 and connected to the telescopic drive assembly 1013 so as to slide in the second mounting groove 10112 under the drive of the telescopic drive assembly 1013, thereby the movable arm 1012 and the fixed arm 1011 form a telescopic motion.

[0045] In this embodiment, the first mounting groove 10111 protects the drive assembly from direct exposure to air and corrosion. The second mounting groove 10112 allows the fixed rod 1011 to provide sufficient support to the movable rod 1012 through its structural strength. Compared to sliding the movable rod 1012 to the outside of the fixed rod 1011, this reduces the use of connecting structures, simplifies the structure, and lowers manufacturing costs. At the same time, the fixed rod 1011 also protects the connection structure between itself and the movable rod 1012, preventing it from easily corroding and ensuring smooth movement between the movable rod 1012 and the fixed rod 1011.

[0046] In some alternative embodiments, the second mounting groove 10112 is configured as an annular groove structure and the movable rod 1012 is configured as a cylindrical structure; wherein, from the perspective of the length direction of the fixed rod 1011, the second mounting groove 10112 is arranged around the first mounting groove 10111, and a notch is provided between the first mounting groove 10111 and the second mounting groove 10112 to avoid the connection structure between the telescopic drive assembly 1013 and the movable rod 1012.

[0047] In this embodiment, the movable rod 1012 is nested in the fixed rod 1011 through the second mounting groove 10112. The movable rod 1012 and the fixed rod 1011 have a large contact area, and the fixed rod 1011 can provide good support for the movable rod 1012 and resist large bending moments to a certain extent.

[0048] In some alternative embodiments, the number of notches is configured to be four and evenly distributed in a circle.

[0049] In this embodiment, connection structures can be provided in the four notches to enable the telescopic drive assembly 1013 and the movable rod 1012 to form a multi-point connection, resulting in better structural stability.
