Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, and in particular to a suspension-type handle support and a treatment device. Background Technology

[0002] In the fields of cosmetic treatments and similar medical devices, the handle, as a key component that directly contacts and operates the patient, is crucial to the work efficiency, operational precision, and occupational health of medical personnel. Especially in scenarios involving prolonged handheld operation, handle hovering technology has become a pressing technical challenge, with the core being achieving effortless operation and stable hovering at any height.

[0003] Currently, there are two operating methods for the handles of beauty treatment devices on the market: One is the bracketless method, where medical staff must manually support and operate the handle throughout the entire process. In this method, when the handle is heavy or the operation time is long, it can easily lead to fatigue for the medical staff, affecting operational accuracy and efficiency. Furthermore, the lack of an effective support mechanism makes it difficult for the handle to be stably suspended at different heights. The second method is the method with a fixed bracket. Although the handle can be suspended at a certain height via a fixed cable, existing bracket designs mostly rely on simple mechanical structures, which cannot achieve stable suspension of the handle at multiple preset or continuous height positions. Medical staff still need to manually adjust the handle height, and the adjustment process may not be smooth, affecting the operating experience.

[0004] To further achieve handle gravity balance and hovering at any height, an electrical control system is typically employed. This system comprises complex components such as control chips, sensors, motors, and control algorithms, achieving hovering by real-time monitoring and adjustment of the handle position. However, such solutions are complex, have high maintenance costs, and require external energy input, increasing the overall energy consumption and cost of the equipment. Furthermore, the introduction of electrical components may introduce potential problems such as electromagnetic interference, affecting the stability and reliability of the equipment.

[0025] This utility model proposes a hovering handle bracket 100.

[0026] Please see Figure 1 , Figure 2, Figure 6 , Figure 8 as well as Figure 10 In one embodiment of this utility model, the hovering handle support 100 is applied to a therapeutic device. The therapeutic device includes a main unit 200 and a therapeutic handle 300 electrically connected to the main unit 200. The hovering handle support 100 includes a support frame assembly 1, a counterweight module 4, a flexible connector 2, and an elastic balance module 3. One end of the support frame assembly 1 is connected to the main unit 200. The flexible connector 2 includes a first connecting segment 21 and a second connecting segment 22 connected together. The first connecting segment 21 is arranged along the extension direction of the support frame assembly 1, and the end of the first connecting segment 21 away from the second connecting segment 22 is connected to the counterweight module 4. The connection between the second connecting segment 22 and the first connecting segment 21 is wound around the other end of the support frame assembly 1 via a first pulley 14, and the end of the second connecting segment 22 away from the first connecting segment 21 is connected to the therapeutic handle 300. The elastic balance module 3 is connected to the counterweight module 4 and is used to compensate for the gravity of the therapeutic handle 300 and to help the therapeutic handle 300 hover at any height within its stroke range.

[0027] In this technical solution, when no external force is applied to the treatment handle 300, the thrust provided by the elastic balance module 3 and the gravity of the counterweight module 4 work together to keep the handle stationary at any height. At this time, the system forces satisfy: F f >|F g +F 重 +F 手 |, where F f It is the sum of the total frictional force of the system (the sliding friction between the flexible connector 2 and the pulley surface, the sliding friction between the flexible connector 2 and each rod, and the moving friction of the counterweight module 4), F g The elastic balance module 3 directly or indirectly provides a thrust (upward direction) to the treatment handle 300, F. 重 It is the gravity (direction downward) of counterweight module 4, F 手 It is the weight of the handle (direction downwards). When no external force is applied to the treatment handle 30°, the frictional force F f It is large enough to overcome any minute unbalanced forces, ensuring the handle remains stationary. When an external force is applied to the treatment handle 300, the treatment handle 300 begins to move. At this time, the thrust F of the elastic balance module 3... g It will adjust in real time according to the movement of the treatment handle 300 to ensure that the treatment handle 300 remains balanced during movement. When an external force (i.e., F) is applied downward to the treatment handle 300... 下 (direction downwards), making F 下 +F g +F 重 +F 手 >F fThe static friction of the system is broken. At this time, the treatment handle 300 moves downward, and the piston rod 312 of the gas spring 31 is stretched. When an external force is applied upward to the treatment handle 300 (i.e., F...), 上 (direction upwards), making F 重 +F 上 +F 手 +F g >F f The static friction of the system is broken. At this time, the treatment handle 300 moves upward, and the piston rod 312 of the gas spring 31 is compressed; that is, when F 下 or F 上 When large enough, the treatment handle 300 will overcome the frictional force F f And move to the new position. When the external force applied to the treatment handle 300 is stopped, the thrust F of the elastic balance module 3... g The controller will automatically adjust and lock in the new position. At this point, the system will re-enter static lock mode, and the controller will remain suspended.

[0028] By combining the counterweight module 4 and the elastic balance module 3, the treatment handle 300 can maintain balance at any height, allowing medical personnel to move the handle with minimal force, significantly reducing operational fatigue. The handle can be stably suspended at any height, enabling medical personnel to more precisely control its position, improving treatment accuracy and effectiveness. Without the need for manual support of the handle's weight, medical personnel can more easily perform prolonged operations, improving work efficiency. This suspended handle support 100 employs a mechanical balancing scheme, which is simple in structure, low in cost, and easy to maintain and adjust. The weight of the counterweight module 4 is adjustable to accommodate handles of different weights, improving the system's flexibility and versatility. The mechanical balancing scheme does not rely on a complex electrical control system, reducing potential problems caused by electrical component failures and improving the stability and reliability of the equipment. Through the above design, the suspended handle support 100 of this embodiment effectively solves the problem of existing handles being difficult to suspend, providing a labor-saving, efficient, and stable solution suitable for beauty treatment instruments and other similar medical devices.

[0029] Specifically, one end of the support frame assembly 1 is connected to the main unit 200 to fix and support the entire hovering handle bracket 100. The support frame assembly 1 can be made of metal or high-strength plastic material to ensure the stability and durability of the structure. The design of the support frame assembly 1 can be adjusted according to the shape and size of the main unit 200 to achieve the best connection effect.

[0030] The function of the flexible connector 2 is to transfer the weight of the treatment handle 300 to the counterweight module 4 and realize the up and down movement of the treatment handle 300 through the first pulley 14. The flexible connector 2 can be made of high-strength rope or chain to ensure reliability and durability during long-term use. To facilitate connection with the treatment handle 300, a hook is provided at the end of the second connecting section 22 away from the first connecting section 21. The treatment handle 300 is provided with a hanging hole, and the hook is connected to the hanging hole of the handle.

[0031] The counterweight module 4 is connected to the first connecting segment 21 of the flexible connector 2 to provide gravity matching the weight of the treatment handle 300. The counterweight module 4 can be composed of multiple adjustable weight blocks, which can be easily adjusted according to different handle weights. The counterweight module 4 can be designed with a detachable structure for easy maintenance and replacement. The flexible connector 2 has the characteristics of low friction coefficient and high axial stiffness. When moving on the support frame assembly 1, it has a low friction coefficient and is easy to move. At the same time, the high axial stiffness of the flexible connector 2 makes it less likely to be stretched and deformed between the treatment handle 300 and the counterweight module 4. In some embodiments, the material of the flexible connector 2 includes at least one of steel wire rope and nylon rope; its structure can be a single cable or multiple cables connected in parallel, in series, or braided.

[0032] In some embodiments, the flexible connector 2 includes a first connecting segment 21 and a second connecting segment 22, as shown in the figure. Figure 10 The second connecting segment 22 refers to the portion of the flexible connector 2 between the treatment handle 300 and the extended support frame assembly 1; the first connecting segment 21 refers to the remaining portions of the flexible connector 2. When the treatment handle 300 moves vertically, the portion of the flexible connecting segment 2 extending into the support frame assembly 1 also changes. Therefore, the description of the first connecting segment 21 and the second connecting segment 22 is merely to distinguish between the end connected to the counterweight module 4 and the end connected to the treatment handle 300; these two are essentially two different locations connected by a single cable, with no clear boundary.

[0033] The elastic balance module 3 is connected to the counterweight module 4 to compensate for the weight of the treatment handle 300 and to enable the treatment handle 300 to hover at any height within its stroke range. The elastic balance module 3 can use a gas spring 31, a constant force spring, or other balancer solutions. The gas spring 31 provides thrust through internal gas pressure and can adjust the thrust in real time to maintain the balance of the handle. The gas spring 31 has a self-locking function, which can automatically lock the position of the handle when the external force disappears. The constant force spring provides a constant tension through the elastic force of the spring, which can effectively compensate for the weight of the handle. The design of the constant force spring can ensure that a stable tension is maintained at different height positions. Other mechanical or hydraulic balancers can also be used, and a suitable balancer solution can be selected according to specific needs.

[0034] Please see Figure 8In one embodiment, the elastic balance module 3 is a gas spring 31, which includes a cylinder 311 and a piston rod 312. The cylinder 311 is fixed on the main unit 200, and the piston rod 312 is connected to the counterweight module 4. In this embodiment, the elastic balance module 3 of the suspended handle support 100 uses a gas spring 31 to achieve the balance and suspension function of the treatment handle 300. The gas spring 31 is composed of a cylinder 311 and a piston rod 312. The cylinder 311, as the fixed part of the gas spring 31, is firmly installed on the main unit 200, providing a stable support foundation for the entire gas spring 31. The piston rod 312 has a telescopic characteristic, and one end of it is tightly connected to the counterweight module 4. Through this connection method, the force of the counterweight module 4 can be effectively transmitted to the gas spring 31, thereby achieving force balance adjustment.When the treatment handle 300 is in a stationary state, i.e., when no external force is applied to it, the gas pressure inside the gas spring 31 is in a relatively stable equilibrium state. At this time, the gas spring 31 applies a stable thrust to the counterweight module 4 through the piston rod 312. This thrust, together with the weight of the counterweight module 4 and the weight of the treatment handle 300, works to achieve force balance in the entire system. The system forces satisfy specific equilibrium conditions. The thrust provided by the gas spring 31 can accurately compensate for the weight difference between the treatment handle 300 and the counterweight module 4. At the same time, the friction within the system is large enough to overcome any possible minor imbalance forces, ensuring that the treatment handle 300 remains stationary at any height. The device remains stationary, achieving a stable hovering effect. When the operator applies external force to the treatment handle 300, the treatment handle 300 begins to move. If an external force is applied downwards, the treatment handle 300 will cause the first connecting segment 21 of the flexible connector 2 connected to it to move downwards, thereby causing the second connecting segment 22 of the flexible connector 2 to lift the counterweight module 4 upwards, causing the counterweight module 4 to have an upward movement tendency. This movement will cause the piston rod 312 of the gas spring 31 to be stretched by an upward force, and the gas pressure inside the gas spring 31 will change. As the piston rod 312 is stretched, the upward thrust provided by the gas spring 31 will be adjusted in real time to balance the gravity change when the counterweight module 4 moves upwards. When the applied external force is sufficient... When the sum of the downward force and the weight of the treatment handle 300 exceeds the sum of the thrust of the gas spring 31, the weight of the counterweight module 4, and the static friction of the system, the static friction is overcome, the treatment handle 300 moves downward, and the piston rod 312 of the gas spring 31 is further stretched. Conversely, when an upward force is applied, the treatment handle 300 releases the lifting force on the counterweight module 4 through the flexible connector 2. The counterweight module 4, under its own weight, tends to move downward, thereby pushing the piston rod 312 of the gas spring 31 to be compressed by downward pressure. The gas pressure inside the gas spring 31 is adjusted accordingly, and the upward thrust provided is reduced in real time. When the applied external force is large enough, the sum of the upward force and the weight of the gas spring 300 exceeds the sum of the thrust of the gas spring 31, the weight of the counterweight module 4, and the static friction of the system, the static friction is overcome, the treatment handle 300 moves downward, and the piston rod 312 of the gas spring 31 is further stretched. When the sum of the thrust of spring 31 and the weight of counterweight module 4 is greater than the sum of the weight of treatment handle 300 and the static friction of the system, the static friction is broken, the treatment handle 300 moves upward, and the piston rod 312 of gas spring 31 is compressed. When the operator stops applying external force to treatment handle 300, gas spring 31 will quickly and automatically adjust its internal gas pressure, thereby changing the thrust. At this time, the thrust provided by gas spring 31 will reach a new balance with the weight of counterweight module 4 and the weight of treatment handle 300, locking treatment handle 300 in a new position. The system re-enters the static locking state, and treatment handle 300 remains suspended, ensuring that it can stably stay in the required position during operation.Using a gas spring 31 as the elastic balance module 3, the characteristics of the gas spring 31 are fully utilized. The gas spring 31 provides thrust through internal gas pressure, and can adjust the thrust in real time and accurately according to the movement of the treatment handle 300, thereby effectively compensating for the gravity changes of the treatment handle 300 and ensuring that the treatment handle 300 can achieve stable hovering at any height throughout the entire stroke range.

[0035] Please see Figure 8 In one embodiment, the counterweight module 4 includes a mounting base 41 and a counterweight ring 42. A mounting post 43 is formed on the mounting base 41, and the counterweight ring 42 is fitted onto the mounting post 43. The mounting base 41 is the basic support component of the counterweight module 4. It has a stable structure and can be effectively connected to other parts of the suspended handle bracket 100. The mounting post 43 is formed on the mounting base 41. The position and layout of the mounting post 43 are designed to ensure that it can provide a stable and suitable fitting space for the counterweight ring 42. The mounting base 41 is made of a high-strength and wear-resistant material to ensure that it can withstand the weight of the counterweight ring 42 and various external forces during long-term use without deformation or damage, thereby ensuring the stability of the entire counterweight module 4. The counterweight ring 42 is a key component for adjusting the weight. It has a ring-shaped design, which facilitates its mounting onto the mounting post 43 of the mounting base 41. Different materials can be selected for the counterweight ring 42 according to actual needs; common materials include metals such as cast iron and steel. These materials have high density and can provide a large weight within a small volume. Multiple counterweight rings 42 can be sequentially mounted on the mounting post 43. By increasing or decreasing the number of counterweight rings 42, the total weight of the counterweight module 4 can be easily adjusted to accommodate treatment handles 300 of different weights. During the use of the therapeutic device, the weight of the treatment handle 300 will vary depending on the model, function, and other factors. To achieve hovering of the treatment handle 300 at any position, the weight provided by the counterweight module 4 needs to be balanced with the weight of the treatment handle 300. When the treatment handle 300 is heavy, more or heavier counterweight rings 42 can be mounted on the mounting post 43 to increase the total weight of the counterweight module 4, allowing the elastic balance module 3 to better compensate for the weight of the treatment handle 300, thereby achieving stable hovering. Conversely, when the treatment handpiece 300 is lighter, the number of counterweight rings 42 on the mounting post 43 can be reduced or a lighter counterweight ring 42 can be replaced to reduce the total weight of the counterweight module 4, so as to achieve balance with the gravity of the treatment handpiece 300. This detachable and adjustable design allows the counterweight module 4 to quickly adapt to the needs of different treatment handpieces 300, greatly improving the versatility and flexibility of the suspension handpiece bracket 100.

[0036] Please see Figure 6 and Figure 8In one embodiment, a clamping head 431 is formed at the end of the mounting post 43 away from the mounting base 41, and the clamping head 431 is connected to the end of the first connecting segment 21 away from the second connecting segment 22. The clamping head 431 is tightly connected to the end of the first connecting segment 21 away from the second connecting segment 22, providing strong protection for the stability and functionality of the entire bracket. The clamping head 431 is formed at the end of the mounting post 43 away from the mounting base 41, and it is a key component connecting the mounting post 43 and the first connecting segment 21. The shape of the clamping head 431 is usually annular or has a structure with a specific groove, which matches the shape of the end of the first connecting segment 21 to achieve precise docking and reliable connection. During the use of the therapeutic device, the counterweight module 4 needs to be connected to the therapeutic handle 300 through the flexible connector 2 to realize the transmission of gravity and balance adjustment. When installing, firstly, the counterweight ring block 42 is sequentially placed on the mounting post 43, and the total weight of the counterweight module 4 is adjusted. Then, the end of the first connecting section 21 away from the second connecting section 22 is inserted into the clamping head 431. The connection method using the clamping head 431 is not only simple and convenient, but also ensures the stability and reliability of the connection, avoiding the problem of unstable suspension of the therapeutic handle 300 due to loose connection. When the treatment handle 300 is moved by an external force, the flexible connector 2 transmits the force to the counterweight module 4. Due to the firm connection between the clamping head 431 and the first connecting section 21, the counterweight module 4 can accurately respond to the movement of the treatment handle 300. It works in conjunction with the elastic balance module 3 to adjust the thrust in real time, so that the treatment handle 300 remains balanced throughout the entire stroke range. When the external force is stopped, the thrust of the elastic balance module 3, the weight of the counterweight module 4, and the weight of the treatment handle 300 are balanced again, and the treatment handle 300 is stably suspended in the new position.

[0037] Please see Figure 3 and Figure 4In one embodiment, the support frame assembly 1 includes a first rod 11, a second rod 12, and a third rod 13. One end of the first rod 11 has a groove 111 for mounting a first pulley 14, and the other end is rotatably connected to one end of the second rod 12. The other end of the second rod 12 is rotatably connected to the third rod 13. The support frame assembly 1 adopts an innovative three-bar folding structure, cleverly combined from the first rod 11, the second rod 12, and the third rod 13. This not only provides stable support for the treatment handle 300 but also greatly facilitates the storage and carrying of the support. The first rod 11 is an important component of the support frame assembly 1. One end of it is designed with a groove 111 for mounting the first pulley 14. The shape and size of the groove 111 are adapted to the first pulley 14, ensuring that the first pulley 14 is securely mounted in the groove 111, guaranteeing the stability and smoothness of the pulley during rotation. The first pulley 14 is usually selected as a high-precision, low-friction bearing 53 pulley to reduce the resistance of the flexible connector 2 when supporting and moving the treatment handle 300. The other end of the first rod 11 is rotatably connected to one end of the second rod 12. One end of the second rod 12 is rotatably connected to the first rod 11, and the other end is rotatably connected to the third rod 13. This rotatable connection may adopt a hinge structure or a pin connection, so that the first rod 11 can rotate flexibly relative to the second rod 12 within a certain angle range, and the second rod 12 can rotate flexibly relative to the third rod 13 within a certain angle range, providing convenience for the folding and unfolding of the support frame.

[0038] Please see Figure 3 and Figure 5 as well as Figure 9In one embodiment, the support frame assembly 1 includes two second pulleys 15, two rotating mounting shafts 16, and a plurality of fasteners 17. One rotating mounting shaft 16 is rotatably inserted through one end of the first rod 11 and one end of the second rod 12. One second pulley 15 is rotatably sleeved on the rotating mounting shaft 16. Two fasteners 17 are respectively connected to both ends of the rotating mounting shaft 16. Another rotating mounting shaft 16 is rotatably inserted through the other end of the second rod 12 and one end of the third rod 13. Another second pulley 15 is rotatably sleeved on the rotating mounting shaft 16. Two other fasteners 17 are respectively connected to both ends of the rotating mounting shaft 16. A second connecting segment 22 is sequentially wound around the first pulley 14 and the two second pulleys 15. The support frame assembly 1 is equipped with two second pulleys 15, which makes the movement of the flexible connector 2 and the treatment handle 300 smoother. The two rotating mounting shafts 16 are key components for the flexible rotation of the support frame assembly 1, enabling a flexible rotating connection between the first rod 11, the second rod 12 and the third rod 13, which facilitates the folding and unfolding of the support frame. Multiple fasteners 17 play a role in fixing and connecting in the support frame assembly 1. For each rotating mounting shaft 16, there are two fasteners 17 connected to its two ends. The fasteners 17 are usually screws to ensure the firmness and reliability of the connection between the rods. Through the action of the fasteners 17, the second pulleys 15 can be firmly fitted onto the rotating mounting shafts 16, while preventing the rotating mounting shafts 16 from moving axially during rotation, ensuring the structural stability of the entire support frame assembly 1. The angle between the rods can be adjusted by manually tightening or loosening the fasteners 17. The second connecting section 22 is part of the flexible connector 2. It is sequentially wound around the first pulley 14 and the two second pulleys 15. During the winding process, the second connecting section 22 must be ensured to be in close contact with the surface of the pulleys to avoid slippage or derailment. This winding method allows the second connecting section 22 to move flexibly under the guidance of the pulleys, accurately transmitting the movement of the treatment handle 300 to the counterweight module 4 and the elastic balance module 3, thereby realizing the suspension function of the treatment handle 300. The design of the rotating mounting shaft 16 and the second pulley 15 allows the rods of the support frame assembly 1 to rotate flexibly, facilitating folding and unfolding operations and adapting to the needs of different scenarios. The second pulley 15 and the rotating mounting shaft 16 are firmly connected by fasteners 17, which not only ensures the structural stability of the support frame assembly 1 under external force and provides reliable support for the treatment handle 300, but also allows for angle adjustment between the rods. The second connecting section 22 is sequentially wound around the first pulley 14 and the two second pulleys 15, forming an accurate transmission path that can accurately transmit force and achieve precise suspension of the treatment handle 300, improving the operational accuracy of treatment.

[0039] For easier storage, please refer to [link / reference]. Figure 3In one embodiment, the second rod 12 has a first receiving groove 121 for receiving the first rod 11, and the third rod 13 has a second receiving groove 131 for receiving the second rod 12. The first receiving groove 121 for receiving the first rod 11 is provided on the second rod 12. The shape and size of the first receiving groove 121 match the first rod 11. When the support frame needs to be folded, the first rod 11 can be smoothly stored in the first receiving groove 121, reducing the overall space occupied by the support frame. The interior of the first receiving groove 121 may be smoothed to prevent the first rod 11 from being scratched or damaged during storage and unfolding. The third rod 13 is the bottom support part of the support frame assembly 1. One end of it is rotatably connected to the second rod 12. The third rod 13 has a second receiving groove 131 for the second rod 12 to be stored. The design of the second receiving groove 131 is similar to that of the first receiving groove 121. Its shape and size can ensure that the second rod 12 can be completely stored in it when folded. The third rod 13 is usually made of a high-strength material, such as aluminum alloy or high-strength plastic, to ensure that it can withstand the corresponding weight without deformation or breakage when supporting the treatment handle 300. When the support frame assembly 1 is in the unfolded state, the first rod 11, the second rod 12 and the third rod 13 are connected in sequence to form a stable support structure. The first pulley 14 is installed in the groove 111 of the first rod 11 and can rotate freely, providing guidance and support for the movement of the flexible connector 2 and the treatment handle 300. The treatment handle 300 is connected to the counterweight module 4 via a flexible connector 2. The weight of the counterweight module 4 and the weight of the treatment handle 300 are balanced by the elastic balance module 3, allowing the treatment handle 300 to be suspended in any position. This unfolded support frame provides stable support for the treatment handle 300, ensuring the stability of the handle and the accuracy of operation during treatment. When the support frame needs to be stored, the first rod 11 is rotated relative to the second rod 12, causing the first rod 11 to gradually move towards the first receiving slot 121. As the first rod 11 rotates, it can be smoothly stored in the first receiving slot 121 when it reaches the appropriate position. Then, the second rod 12 is rotated relative to the third rod 13, causing the second rod 12 to move towards the second receiving slot 131 and finally be completely stored in the second receiving slot 131. At this time, the entire support frame assembly 1 is folded into a more compact shape, greatly reducing its space occupation and facilitating storage and carrying. When unfolding the support frame, the operation sequence is the reverse of the folding process. First, pull the second rod 12 out of the second receiving groove 131 and adjust it to a suitable angle so that it forms a stable connection with the third rod 13. Then, pull the first rod 11 out of the first receiving groove 121 and rotate it to the position connected with the second rod 12 to complete the unfolding of the support frame. The whole unfolding process is simple and quick, and the operator can easily complete the operation.

[0040] Further, please refer to Figure 6 and Figure 7 In one embodiment, the main unit 200 has a storage slot 210 for receiving the support frame assembly 1. The support frame assembly 1 includes a positioning pin 18. A strip hole 132 is provided at the end of the third rod 13 away from the second rod 12. The positioning pin 18 passes through the strip hole 132, and its two ends are respectively connected to the opposite side walls of the storage slot 210. By providing the storage slot 210 on the main unit 200 and configuring the positioning pin 18 in the support frame assembly 1, convenient storage and stable positioning of the support frame assembly 1 are achieved, effectively improving the overall practicality and portability of the device. The main unit 200, as the core control and support component of the therapeutic instrument, has a dedicated storage slot 210 on its surface. The shape and size of the storage slot 210 are designed to match the overall contour of the support frame assembly 1. The depth of the storage slot 210 is moderate, ensuring that the support frame assembly 1 is completely housed without increasing the overall thickness of the main unit 200 due to excessive depth. Its inner wall is smoothed to reduce wear on the support frame assembly 1 and facilitates the insertion and removal of the support frame assembly 1. The storage slot 210 not only makes the device neater and more aesthetically pleasing when not in use but also protects the support frame assembly 1 from external impacts and damage. The support frame assembly 1 consists of multiple rods connected by a rotating connection, enabling the support frame assembly 1 to fold and unfold. A strip-shaped hole 132 is provided at the end of the third rod 13 furthest from the second rod 12. The length and width of the strip-shaped hole 132 are determined according to actual design requirements, providing suitable space for the positioning pin 18 to pass through. The positioning pin 18 is an important positioning component in the support frame assembly 1. The positioning pin 18 passes through the strip hole 132 on the third rod 13, and its two ends are respectively connected to the opposite side walls of the storage groove 210. This connection method can be a direct fixed connection, such as screwing the two ends of the positioning pin 18 into the threaded holes on the side walls of the storage groove 210 through a threaded connection. When the support frame assembly 1 is in the unfolded state, the positioning pin 18 has a certain amount of room to move within the strip hole 132, allowing the third rod 13 to move within a certain range relative to the positioning pin 18, thereby realizing the flexible adjustment of the support frame assembly 1. When it is necessary to store the support frame assembly 1 into the main unit 200, by rotating and folding the support frame assembly 1, the third rod 13 is gradually brought closer to the storage groove 210, and finally the positioning pin 18 is accurately inserted into the connection position on the side wall of the storage groove 210, completing the positioning and fixing of the support frame assembly 1. The slot 132 has an upper center and a lower center. The third rod 13 can rotate 180 degrees up and down around the positioning pin 18. When the third rod 13 is flipped up, it can move along the slot 132 within the range from the upper center to the lower center. When the third rod 13 is flipped up, the positioning pin 18 coincides with the upper center of the slot 132, and the third rod 13 is in a stable vertical state. When the third rod 13 is flipped down, the positioning pin 18 coincides with the lower center of the slot 132, and all rods are folded and stored in the storage slot 210 of the main unit 200.

[0041] Please see Figure 6 and Figure 7 In one embodiment, the main unit 200 has a mounting slot 220. The hovering handle bracket 100 includes a connecting seat 5, which is connected to the wall of the mounting slot 220 and located at the opening of the mounting slot 220. The counterweight module 4 and the elastic balance module 3 are both housed within the mounting slot 220. The connecting seat 5 has a through hole 51, through which the second connecting section 22 passes and connects to the counterweight module 4. A column 52 is formed at one end of the connecting seat 5 near the bottom of the mounting slot 220. A bearing 53 is fitted onto the column 52, and the outer peripheral wall of the bearing 53 engages with the inner peripheral wall of the mounting slot 220. Through the specific mounting slot 220 on the main unit 200 and the clever cooperation of components such as the connecting seat 5, the counterweight module 4, and the elastic balance module 3, the stable installation and flexible hovering of the handle bracket are achieved, improving the overall performance of the device and the user experience. The main unit 200 has a mounting slot 220. This mounting slot 220 ensures that all components of the suspended handle bracket 100 are fully accommodated without increasing the overall thickness of the main unit 200 due to excessive depth. The slot design facilitates the installation and removal of the handle bracket, while also providing some protection for the internal components, preventing external dust and debris from entering and affecting their normal operation. The connecting seat 5 is made of high-strength plastic or metal material, possessing good mechanical properties and wear resistance. The connecting seat 5 has a through hole 51, the diameter of which is precisely designed according to the dimensions of the second connecting section 22 to ensure that the second connecting section 22 can pass through smoothly. The position of the through hole 51 is located near the center of the connecting seat 5 to ensure the balance of the handle bracket after installation. A column 52 is formed at the end of the connecting seat 5 away from the groove of the mounting slot 220. A bearing 53 is fitted on the column 52. The outer peripheral wall of the bearing 53 engages with the inner peripheral wall of the mounting slot 220. This engagement method allows the connecting seat 5 to be rotated, ensuring a stable connection between the bearing 53 and the mounting slot 220, while also allowing the connecting seat 5 to rotate within a certain range, providing a basis for the flexible hovering of the handle bracket. The counterweight module 4 and the elastic balance module 3 are both housed within the mounting slot 220. The counterweight module 4 is connected to the connecting seat 5 through a second connecting section 22. The second connecting section 22 passes through a through hole 51 on the connecting seat 5, transferring the weight of the counterweight module 4 to the connecting seat 5, thereby affecting the balance of the handle bracket. The weights of the elastic balance module 3 and the counterweight module 4 balance each other, allowing the handle bracket to hover at any position. The elastic balance module 3 is installed at the bottom or side of the mounting slot 220, cooperating with the counterweight module 4 to jointly adjust the balance of the handle bracket.

[0042] Please see Figure 7In one embodiment, the connecting seat 5 has a groove 54 communicating with the through hole 51. A third pulley 55 is rotatably mounted in the groove 54, and the second connecting section 22 is wound around the third pulley 55. The suspended handle bracket 100 includes a cover plate 6, which covers the opening of the mounting groove 220, and has openings and clearance openings corresponding to the through hole 51 and the connection between the support frame assembly 1 and the main unit 200, respectively. The connecting seat 5 further has a groove 54 communicating with the through hole 51. The size design of the groove 54 ensures that the third pulley 55 can rotate freely in the groove 54. The depth of the groove 54 is moderate, which can ensure the stable installation of the third pulley 55 without occupying too much space. A third pulley 55 is rotatably provided within the groove 54. The third pulley 55 is made of a high-strength, low-friction material, such as high-quality plastic or metal bearing 53, and has good wear resistance and rotational flexibility. The second connecting section 22 is wound around the third pulley 55. When the treatment handle 300 is repositioned, the second connecting section 22 can slide smoothly under the guidance of the third pulley 55, reducing friction with the connecting seat 5, reducing energy loss, and making the operation of the handle support easier and more flexible. At the same time, the presence of the third pulley 55 can also effectively prevent the second connecting section 22 from getting stuck or tangled during movement, improving the stability and reliability of the handle support operation. The suspended handle support 100 is equipped with a cover plate 6, which is made of a material and color that matches the appearance of the main unit 200, and has good decorative and overall appearance. The cover plate 6 is shaped to fit the opening of the mounting groove 220, completely covering the opening and protecting the internal components while enhancing the appearance. An opening is provided on the cover plate 6 corresponding to the through hole 51, with a diameter slightly smaller than that of the through hole 51. This ensures the second connecting section 22 can pass through smoothly without compromising the cover plate 6's protection of the internal components of the handle bracket. Furthermore, the cover plate 6 has a clearance opening at the connection point between the support frame assembly 1 and the main unit 200. This clearance opening is designed to allow the connection between the support frame assembly 1 and the main unit 200 to pass smoothly, preventing interference from the cover plate 6 and ensuring the normal installation and use of the handle bracket.
