[0037] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0038] See also Figures 1 to 8 The present embodiment provides a drying device, including a clothes drying rack 100 and a winding structure 200, the clothes drying rack 100 includes a first drying rod 110 and a second drying rod 120, the second drying rod 120 has a storage position that fits the first drying rod 110, and an unfolded position that is spaced apart from the first drying rod 110; the winding structure 200 includes a coil spring component 210 and a connecting belt 220, one end of the connecting belt 220 is connected to the coil spring component 210, one of the first drying rod 110 and the second drying rod 120 is used to support the coil spring component 210, and the other is connected to the other end of the connecting belt 220; the coil spring component 210 has an unfolded state and a rolled state, when the second drying rod 120 and the first drying rod 110 are away from each other, the coil spring component 210 is in the unfolded state and releases the connecting belt 220, and the distance between the second drying rod 120 and the first drying rod 110 can be adjusted by the coil spring component 210.

[0039] When the distance between the second air-drying rod 120 and the first air-drying rod 110 needs to be increased, the second air-drying rod 120 is pulled down, and the sum of the external force of pulling down the second air-drying rod 120 and the gravity of the second air-drying rod 120 makes the coil spring component 210 in the unfolded state and releases the connecting belt 220; when the distance between the second air-drying rod 120 and the first air-drying rod 110 needs to be reduced, the second air-drying rod 120 is lifted up, and the difference between the gravity of the second air-drying rod 120 and the external force of lifting up the second air-drying rod 120 makes the coil spring component 210 switch to the reeled state under its own elasticity and reel the connecting belt 220; therefore, by means of the cooperation between the coil spring component 210 and the connecting belt 220, the distance between the second air-drying rod 120 and the first air-drying rod 110 can be adjusted by only pulling down and lifting up the second air-drying rod 120, which has a simple structure and is easy to operate. Furthermore, the coil spring component 210 and the connecting belt 220 have strong structural stability and low failure rate.

[0040] Specifically, when the second air-drying rod 120 needs to be moved away from the first air-drying rod 110, the operator only needs to pull down the second air-drying rod 120 by hand, that is, to apply a downward first external force to the second air-drying rod 120. Under the action of the first external force, the force applied by the connecting belt 220 to the coil spring component 210 is equal to the sum of the gravity of the second air-drying rod 120 and the first external force, and the sum of the two is greater than the predetermined tension value, so that the coil spring component 210 is elastically deformed and the connecting belt 220 is released, and the second air-drying rod 120 is away from the first air-drying rod 110. The predetermined tension value is a critical tension that can cause the coil spring component 210 to be elastically deformed. When the tension applied to the coil spring component 210 is greater than the critical tension, the coil spring component 210 is elastically deformed.

[0041] When the second drying rod 120 is in the unfolded position, the rebound force of the coil spring component 210 is less than or equal to the gravity of the second drying rod 120 so that the coil spring component 210 will not rebound against the gravity of the second drying rod 120, and the second drying rod 120 can be suspended in the unfolded position. That is, when the operator releases the second drying rod 120, the second drying rod 120 can be suspended at any position away from the first drying rod 110.

[0042] By balancing the gravity of the second drying rod 120 and the rebound force of the coil spring component 210, the second drying rod 120 can be suspended at any position away from the first drying rod 110. The distance between the second drying rod 120 and the first drying rod 110 can be adjusted as needed, which is convenient for adjustment.

[0043] After the coil spring component 210 is elastically deformed, the coil spring component 210 has a tendency to recover the deformation under the action of its own elasticity, and then the coil spring component 210 applies a rebound force to the connecting belt 220 connected thereto. When the force exerted by the connecting belt 220 on the coil spring component 210 is greater than the rebound force, the coil spring component 210 will not rebound. When the force exerted by the connecting belt 220 on the coil spring component 210 is less than the rebound force, the coil spring component 210 rebounds under the action of its own elasticity and returns to the undeformed state. Therefore, according to the properties of the coil spring component 210 itself, the magnitude of the predetermined tension value and the magnitude of the rebound force are set, and the predetermined tension values ​​and rebound forces corresponding to different coil spring components 210 may be different.

[0044] The connecting belt 220 is in the shape of a long strip and plays a connecting role. During the process of adjusting the distance between the second drying rod 120 and the first drying rod 110, the connecting belt 220 itself does not undergo elastic deformation. In order to adapt to the installation space, the connecting belt 220 can be bent and extended, and the bending does not affect the performance of the connecting belt 220. The connecting belt 220 can be a thin sheet, or the cross-sectional shape can be circular, elliptical or other shapes, and its shape is not limited here. The connecting belt 220 can be a nylon belt or a steel belt, and its material is not limited here.

[0045] In some embodiments, the drying device further includes a damping structure, which selectively contacts the connecting belt 220. When the damping structure contacts the connecting belt 220, the damping structure clamps or compresses the connecting belt 220 to limit the connecting belt 220, so that the second drying rod 120 remains in the current position, and the distance between the second drying rod 120 and the first drying rod 110 remains unchanged, and heavy objects can be hung on the second drying rod 120 or clothes can be removed. When the damping structure is out of contact with the connecting belt 220, under the action of an external force, the coil spring component 210 can release or reel in the connecting belt 220, and the distance between the first drying rod 120 and the second drying rod 110 can be adjusted.

[0046] Optionally, the damping structure includes a damping part and a driving part, the driving part is used to drive the damping part to move between a contact position and a release position, the damping part clamps or presses the connecting belt 220 at the contact position, and the damping part moves away from and releases the connecting belt 220 at the release position. The damping part can be a damping block or a damping wheel, and can be made of rubber material. The driving part can be a cylinder or a hydraulic cylinder.

[0047] In order to facilitate the operation of the driving part, an operating member may be provided on the second air-drying rod 120, and the operating member is electrically connected to the driving part, and the operator can control the start and stop of the driving part by operating the operating member. The operating member may be a button, a knob or a lever. Taking a button as an example, after pulling down the second air-drying rod 120 to an appropriate position, press the button once, and the driving part drives the damping part to move to the contact position, and the damping part clamps or presses the connecting belt 220, which plays a limiting role on the second air-drying rod 120. Press the button again, and the driving part drives the damping part to move to the release position, and the damping part moves away from and releases the connecting belt 220, and at this time, the second air-drying rod 120 can move under the action of external force.

[0048] In some embodiments, the drying device is an electric clothes drying machine, and the drying device further comprises a main machine, and the first drying rod 110 is hung on the main machine. Figure 1 , Figure 2 , Figure 4 and Figure 8 The first drying rod 110 is connected to the main machine via a connecting rope 310, and the connecting rope 310 can be released and reeled to adjust the distance between the first drying rod 110 and the main machine. The main machine can adopt an existing main machine. In some embodiments, the drying device is a manual clothes drying machine, and the first drying rod 110 can be fixed to the roof via the connecting rope 310, or the first drying rod 110 is supported by a supporting rod.

[0049] In this embodiment, the connection rope 310 is fixedly connected to the first drying rod 110. Specifically, the drying device further includes a fixed clamp 320 and a fixed clamp seat 330. The end of the connection rope 310 has a clamp joint, which can be clamped into the fixed clamp 320. The fixed clamp 320 is installed on the fixed clamp seat 330, and the fixed clamp seat 330 can be inserted into the fixing hole of the first drying rod 110. Therefore, the assembly of the connection rope 310 and the first drying rod 110 is facilitated, thereby simplifying the fixing method of the drying device.

[0050] The connecting rope 310 is in the shape of a long strip and serves as a connection. The connecting rope 310 itself does not undergo elastic deformation. In order to adapt to the installation space, the connecting rope 310 can be bent and extended, and the bending does not affect the performance of the connecting rope 310. The cross-sectional shape of the connecting rope 310 can be circular, oval, square or other shapes, and its shape is not limited here. The connecting rope 310 can be a nylon rope or a steel wire rope, and its material is not limited here.

[0051] In this embodiment, the coil spring component 210 has an extended state and a reeled state. When the second drying rod 120 moves away from the first drying rod 110 under the action of the first external force, the coil spring component 210 is in an extended state; when the second drying rod 120 approaches the first drying rod 110, the coil spring component is in a reeled state. The coil spring component 210 may be a constant force coil spring. When the second drying rod 120 moves away from the first drying rod 110 under the action of the first external force, the constant force coil spring is extended relative to the coil spring axis and the connecting belt 220 is released.

[0052] Among them, the constant force coil spring is an existing structure. The constant force coil spring is made of high-strength stainless steel, and the high-strength steel strip is shaped by spring production equipment. When the external force straightens it, the constant force coil spring will naturally roll back and generate a rebound force. Regardless of the size of the load or the degree of extension of the constant force coil spring, the constant force coil spring will exert basically the same force on the load. In the drying device, the constant force coil spring is responsible for bearing the weight of the second drying rod 120 and enabling it to move up and down smoothly, and can hover at any position. By adjusting the tension of the constant force coil spring, the size, weight and movement stability of the different second drying rods 120 can be adapted.

[0053] The constant force coil spring can provide a constant pulling force to the load, that is, the rebound force is constant. It only needs to be set to be less than or equal to the gravity of the second drying rod 120 so that the gravity of the second drying rod 120 and the rebound force of the coil spring component 210 can be balanced so that the second drying rod 120 can be suspended at any position away from the first drying rod 110.

[0054] When the second air-drying rod 120 is suspended at any position away from the first air-drying rod 110 and is acted upon by a second upward external force, the force applied by the connecting belt 220 to the coil spring component 210 is equal to the difference between the gravity of the second air-drying rod 120 and the second external force, and the difference between the two is less than the rebound force, so that the coil spring component 210 rebounds under the action of the rebound force and the connecting belt 220 is recovered, so as to pull the second air-drying rod 120 to move toward a position close to the first air-drying rod 110. The second upward external force acts on the second air-drying rod 120, so that the force applied by the connecting belt 220 to the coil spring component 210 is less than the rebound force of the coil spring component 210, and then the elastic deformation of the coil spring component 210 is restored, so as to recover the connecting belt 220, and the second air-drying rod 120 is moved closer to the first air-drying rod 110.

[0055] In some embodiments, the second external force is an instantaneous external force, and the second drying rod 120 can be automatically moved closer to the first drying rod 110 by just lifting the second drying rod 120 slightly, so that the storage is convenient. In some embodiments, the second external force is applied to the first drying rod 110 and maintained for a first set time. When storing the second drying rod 120, the second drying rod 120 needs to be held upward until the second drying rod 120 is completely stored.

[0056] When the second drying rod 120 moves toward a position close to the first drying rod 110, if the second drying rod 120 is subjected to a third downward external force, and the sum of the gravity of the second drying rod 120 and the third external force is greater than a predetermined pulling force value, the second drying rod 120 changes its movement direction and moves away from the first drying rod 110; otherwise, the second drying rod 120 continues to move toward a position close to the first drying rod 110 until the second drying rod 120 stops moving when it abuts against the first drying rod 110.

[0057] During the process of retracting the second drying rod 120, the second drying rod 120 approaches the first drying rod 110. If the second drying rod 120 is subjected to a third downward external force, the moving direction of the second drying rod 120 will be changed, so that the second drying rod 120 moves away from the first drying rod 110, which is suitable for reducing the distance between the second drying rod 120 and the first drying rod 110. That is to say, when the second drying rod 120 is suspended in the first position and the distance between the second drying rod 120 and the first drying rod 110 needs to be increased, the second drying rod 120 is pulled downward; when the distance between the second drying rod 120 and the first drying rod 110 needs to be reduced, the second drying rod 120 is lifted upward and a third external force is applied downward to the second drying rod 120 at an appropriate position. When the sum of the gravity of the second drying rod 120 and the third external force is greater than a predetermined pulling force value, the second drying rod 120 changes its movement direction and moves away from the first drying rod 110, so that in the process of retracting the second drying rod 120, the second drying rod 120 can be suspended at a second position higher than the first position by changing the force.

[0058] By providing the coil spring component 210, it is convenient to adjust the distance between the second drying rod 120 and the first drying rod 110, which not only improves the space utilization of the drying device, but also makes the use of the drying device more convenient. The winding structure 200 is adopted to realize gravity locking and light lifting release. The structure is simple to realize the unfolding and storage of the drying device without complicated operation steps. On the one hand, it reduces the difficulty of using the drying device, and on the other hand, it simplifies the structure of the drying device and improves the reliability of the drying device.

[0059] When the second drying rod 120 is in the storage position, the second drying rod 120 is plugged into the first drying rod 110, and / or the second drying rod 120 is magnetically connected to the first drying rod 110. Compared with a simple abutment, the plugging and / or magnetic connection between the first drying rod 110 and the second drying rod 120 makes the connection between the first drying rod 110 and the second drying rod 120 more stable, preventing the second drying rod 120 from easily detaching from the first drying rod 110 due to wind or other external effects.

[0060] There are many ways to set up the magnetic connection, which may be that the first air-drying rod 110 is provided with a magnet, and the second air-drying rod 120 is provided with a metal part that can be attracted by the magnet; or the second air-drying rod 120 is provided with a magnet, and the first air-drying rod 110 is provided with a metal part that can be attracted by the magnet; or both the first air-drying rod 110 and the second air-drying rod 120 are provided with magnets. It should be additionally explained that there are also many ways to set up the magnet and the metal, for example, embedding a magnet on the first air-drying rod 110 and / or the second air-drying rod 120; or, providing a magnetic coating on the surface of the first air-drying rod 110 and / or the second air-drying rod 120; or, both the first air-drying rod 110 and the second air-drying rod 120 are directly made of magnetic materials; or, embedding a metal part on the first air-drying rod 110 or the second air-drying rod 120; or, the first air-drying rod 110 or the second air-drying rod 120 is directly made of metal materials.

[0061] In this embodiment, when the second drying rod 120 is in the storage position, the second drying rod 120 is plugged into the first drying rod 110, and the second drying rod 120 is magnetically connected to the first drying rod 110. Specifically, the first drying rod 110 is provided with a magnet 400, and the second drying rod 120 is provided with a metal part that can be attracted by the magnet 400, or the second drying rod 120 is directly made of metal material. The magnetic bonding design not only enhances the overall stability of the drying device, but also makes the appearance of the stored drying device more neat and beautiful.

[0062] One of the second drying rod 120 and the first drying rod 110 is provided with a protrusion 121, and the other is provided with a groove 111. In the storage position, the protrusion 121 is plugged into the groove 111. In this embodiment, the second drying rod 120 is provided with a protrusion 121 extending along its length, and the first drying rod 110 is provided with a groove 111 extending along its length, and the protrusion 121 can be inserted into the groove 111. It can be understood that in the actual storage process, under the rebound effect of the coil spring component 210, the distance between the first drying rod 110 and the second drying rod 120 is reduced. When the protrusion 121 is inserted into the groove 111, the first drying rod 110 and the second drying rod 120 have overlapping heights in the vertical direction, which further reduces the occupied volume of the entire drying device when stored, thereby further improving user satisfaction.

[0063] Furthermore, the first drying rod 110 is provided with a groove portion 111, and a magnet 400 is provided in the groove portion 111, and the second drying rod 120 can be magnetically attracted to the magnet 400. By providing the magnet 400 in the groove portion 111, the space is fully utilized, so that the second drying rod 120 and the first drying rod 110 are more stably attached. When the second drying rod 120 and the first drying rod 110 are plugged in, they are magnetically attracted to achieve automatic attachment, and this labor-saving recovery mechanism improves the convenience of use of the drying device.

[0064] When the second drying rod 120 is in the storage position, the connecting belt 220 is in a taut state under the action of the coil spring component 210. Not only does it make the second drying rod 120 fit stably with the first drying rod 110, but it can also maintain a certain tension when pulling down the second drying rod 120, thereby improving the user experience.

[0065] In this embodiment, the coil spring component 210 is disposed inside the second air-drying rod 120, and one end of the connecting belt 220 away from the coil spring component 210 passes through the second air-drying rod 120 and is detachably connected to the first air-drying rod 110. By arranging the coil spring component 210 inside the second air-drying rod 120, the space is fully utilized and the appearance is neat. The connecting belt 220 is detachably connected to the first air-drying rod 110, which is convenient for installation, removal and replacement. In other embodiments, the coil spring component 210 is disposed inside the first air-drying rod 110, and one end of the connecting belt 220 away from the coil spring component 210 passes through the first air-drying rod 110 and is detachably connected to the second air-drying rod 120.

[0066] When the second drying rod 120 is pulled down, a first external force is applied to the second drying rod 120. Under the action of the first external force, the second drying rod 120 moves away from the first drying rod 110, the coil spring component 210 gradually unfolds, and the connecting belt 220 is released and then moved out of the second drying rod 120; when recovering, the coil spring component 210 rebounds under the action of the rebound force and recovers the connecting belt 220, so that the connecting belt 220 is stored in the second drying rod 120 to save space.

[0067] See also Figure 4 and Figure 5 The winding structure 200 further includes an installation box 230, in which the coil spring component 210 is accommodated, one end of the coil spring component 210 can be pulled out of the installation box 230 by the connecting belt 220, and the installation box 230 is detachably connected to the second air-drying rod 120. Installing the coil spring component 210 in the installation box 230 can not only protect the coil spring component 210, but also prevent the coil spring component 210 from being twisted when the connecting belt 220 pulls the coil spring component 210, thereby ensuring stable adjustment of the spacing between the first air-drying rod 110 and the second air-drying rod 120. The installation box 230 is detachably connected to the second air-drying rod 120, which is convenient for installation, disassembly and replacement.

[0068] The installation box 230 and the second air-drying rod 120 can be connected by snapping, bolting, bonding or magnetic attraction. Optionally, a snap structure is provided on the outer wall of the installation box 230, and the installation box 230 is snapped onto the second air-drying rod 120 by the snap structure, so as to prevent the installation box 230 from shaking inside the second air-drying rod 120. Of course, a positioning hole can also be provided on the installation box 230, and the installation box 230 can also be fixed on the second air-drying rod 120 by matching the positioning hole with a positioning column provided on the second air-drying rod 120.

[0069] Specifically, see Figure 6 The second drying rod 120 is a split structure, and the second drying rod 120 includes a drying rod 122 and a drying cover 123. The drying rod 122 has a mounting groove 1221, and the mounting groove 1221 is used to accommodate the mounting box 230 and part of the connecting belt 220. The drying cover 123 is buckled on the drying rod 122 to close the mounting groove 1221. It can be understood that in the actual assembly process, the drying cover 123 can be opened, and then the mounting box 230 and the connecting belt 220 are installed into the mounting groove 1221 through the notch of the mounting groove 1221, and the connecting belt 220 is straightened, and finally the drying cover 123 is buckled on the first drying rod 122. This installation method is very simple and can prevent the connecting belt 220 from being entangled in the second drying rod 120.

[0070] Furthermore, the installation groove 1221 is arranged to penetrate to the end of the second air-drying rod 120, and the second air-drying rod 120 also includes a second end head 124, and the second end head 124 is plugged into the end of the second air-drying rod 120 to block the installation groove 1221. The installation groove 1221 is arranged to penetrate to the end of the second air-drying rod 120, which is convenient for installing components such as the connecting belt 220, and the second end head 124 is plugged into the end of the second air-drying rod 120 to play a role of blocking and limiting.

[0071] Optionally, the installation box 230 is a splicing structure, and the installation box 230 includes a first box body 231 and a second box body 232, and the first box body 231 is buckled on the second box body 232. Thus, the coil spring component 210 can be easily installed in the installation box 230, and the coil spring component 210 can be easily replaced.

[0072] A coil spring shaft for installing the coil spring component 210 is arranged in the installation box 230. One end of the coil spring component 210 is connected to the coil spring shaft, and the other end is connected to the connecting belt 220. The coil spring component 210 can be unfolded or reeled relative to the coil spring shaft.

[0073] The connecting belt 220 and the coil spring component 210 can be directly connected or indirectly connected. In this embodiment, the connecting belt 220 and the coil spring component 210 are connected by a wire buckle 240. The wire buckle 240 is used to connect the connecting belt 220 and the coil spring component 210, which is convenient for connection and assembly, and is conducive to improving the connection stability of the connecting belt 220 and the coil spring component 210.

[0074] Alternatively, see Figure 5The wire buckle 240 is a splicing structure. The wire buckle 240 includes a first buckle plate 241 and a second buckle plate 242. The first buckle plate 241 is provided with a clamping hole 2411. The first end of the connecting belt 220 is provided with a first clamping head 221, and the first clamping head 221 can be clamped into the clamping hole 2411. In this way, it can ensure that the first end of the connecting belt 220 is stably connected to the wire buckle 240. Further optionally, the end of the coil spring component 210 is provided with two limiting grooves 211, the first buckle plate 241 is provided with two limiting protrusions, and the second buckle plate 242 is provided with a limiting slot 2421 that cooperates with the limiting protrusion. In the actual assembly process, the end of the coil spring component 210 is attached to the second buckle plate 242, and when the first buckle plate 241 is buckled on the second buckle plate 242, the limiting protrusion on the first buckle plate 241 passes through the limiting groove 211 and is inserted into the limiting slot 2421. Thereby, the end of the coil spring member 210 can be firmly fixed to the thread buckle 240 .

[0075] See also Figure 6 , a limiting member 130 is provided at the end of the second air-drying rod 120, and the limiting member 130 is used to limit the coil spring component 210 from escaping from the second air-drying rod 120; and / or, a guide member 140 is provided at the end of the second air-drying rod 120, and the guide member 140 guides the connecting belt 220 to pass through the second air-drying rod 120. By providing the limiting member 130, the coil spring component 210 is limited from escaping from the second air-drying rod 120, so as not to affect the smooth recovery of the coil spring component 210. By providing the guide member 140, the connecting belt 220 is guided, so that the connecting belt 220 located outside the second air-drying rod 120 is always in a vertical state, ensuring the movement stability of the second air-drying rod 120.

[0076] Specifically, the stopper 130 is provided with a through hole for allowing the connecting belt 220 to pass through, and the wire buckle 240 can abut against the stopper 130. When the second drying rod 120 is away from the first drying rod 110, when the wire buckle 240 abuts against the stopper 130, the stopper 130 limits the wire buckle 240, and the second drying rod 120 moves to the farthest distance. The stopper 130 is clamped, bolted, or bonded to the second drying rod 120.

[0077] The guide member 140 is a wire wheel, which can rotate relative to the second air-drying rod 120. The second air-drying rod 120 is provided with a second wire-gripping groove 125 corresponding to the wire wheel. The second end of the connecting belt 220 passes through the wire wheel and passes through the second wire-gripping groove 125 to connect with the first air-drying rod 110. Therefore, in the actual adjustment process, the connecting belt 220 can ensure the stability of the position of the connecting belt 220 under the joint restriction of the wire wheel and the second wire-gripping groove 125 to prevent the connecting belt 220 from being entangled or knotted and stuck. During the installation process, the second end of the connecting belt 220 is extended out of the second air-drying rod 120, and the second terminal 124 is plugged into the end of the second air-drying rod 120.

[0078] See also Figure 7The connecting belt 220 can be connected to the first airing rod 110. Specifically, the first airing rod 110 is provided with a first wire clamping groove 112, and the second end of the connecting belt 220 passes through the second wire clamping groove 125 and is connected to the first wire clamping groove 112 on the first airing rod 110.

[0079] Furthermore, the first airing rod 110 is hollow, both ends of the first airing rod 110 are open, and the first wire clamping groove 112 is open at one end of the end of the first airing rod 110, that is, the first wire clamping groove 112 is a U-shaped groove, which is convenient for clamping the connecting belt 220. The first airing rod 110 also includes a first end 113, and the first end 113 is plugged into the end of the first airing rod 110. In the actual installation process, it is only necessary to clamp the second clamping head 222 of the connecting belt 220 into the first wire clamping groove 112, and then insert the first end 113 into the end of the first airing rod 110, which facilitates the connection between the connecting belt 220 and the first airing rod 110. The first airing rod 110 is hollow, which can reduce the weight of the first airing rod 110, thereby helping to reduce the weight of the entire drying device.

[0080] In this embodiment, two groups of winding structures 200 are provided, two coil spring components 210 are provided in the middle of the second drying rod 120, and two connecting belts 220 are distributed at both ends of the length direction of the first drying rod 110. By providing two groups of winding structures 200, the force on the second drying rod 120 is balanced.

[0081] When the second air-drying rod 120 is in the storage position, the second air-drying rod 120 fits with the first air-drying rod 110, the protrusion 121 of the second air-drying rod 120 is inserted into the groove 111 of the first air-drying rod 110, the second air-drying rod 120 and the first air-drying rod 110 are magnetically attracted, and the connecting belt 220 is in a taut state. When the second air-drying rod 120 needs to be away from the first air-drying rod 110, it is only necessary to pull down the second air-drying rod 120, that is, to apply a first external force to the second air-drying rod 120. Under the action of the first external force, the force applied by the connecting belt 220 to the coil spring component 210 is equal to the sum of the gravity of the second air-drying rod 120 and the first external force, and the sum of the two is greater than the predetermined tension value, so that the coil spring component 210 is elastically deformed and the connecting belt 220 is released, and the second air-drying rod 120 is away from the first air-drying rod 110.

[0082] When the second drying rod 120 moves to the desired position, the second drying rod 120 is released, that is, the first external force disappears, and the rebound force of the coil spring component 210 is less than or equal to the gravity of the second drying rod 120 so that the second drying rod 120 can hover at a position away from the first drying rod 110.

[0083] When the distance between the second drying rod 120 and the first drying rod 110 needs to be increased, the second drying rod 120 is pulled downward to further move away from the first drying rod 110. When the first external force applied downward cannot further pull the second drying rod 120, it indicates that the wire buckle 240 is in contact with the stopper 130, and the second drying rod 120 has reached the lowest position.

[0084] When the distance between the second air-drying rod 120 and the first air-drying rod 110 needs to be reduced, the second air-drying rod 120 is lightly lifted upward, and the second air-drying rod 120 is acted upon by the second external force upward. The force applied by the connecting belt 220 to the coil spring component 210 is equal to the difference between the gravity of the second air-drying rod 120 and the second external force, and the difference between the two is less than the rebound force, so that the coil spring component 210 rebounds under the action of the rebound force and retracts the connecting belt 220, so as to pull the second air-drying rod 120 to move toward a position close to the first air-drying rod 110. A third external force is applied downward to the second air-drying rod 120 at an appropriate position, and the sum of the gravity of the second air-drying rod 120 and the third external force is greater than a predetermined pulling force value, so that the second air-drying rod 120 changes its movement direction and moves in a direction away from the first air-drying rod 110. The second air-drying rod 120 is released, and the second air-drying rod 120 can be suspended, so that in the process of retracting the second air-drying rod 120, the second air-drying rod 120 can be suspended at a desired position by changing the force.

[0085] When it is necessary to recycle the second drying rod 120, the second drying rod 120 is gently lifted upward, and the second drying rod 120 is subjected to the second external force upward. The force applied by the connecting belt 220 to the coil spring component 210 is equal to the difference between the gravity of the second drying rod 120 and the second external force, and the difference between the two is less than the rebound force, so that the coil spring component 210 rebounds under the action of the rebound force and recycles the connecting belt 220, so as to pull the second drying rod 120 to a position close to the first drying rod 110, until the protrusion 121 of the second drying rod 120 is inserted into the groove 111 of the first drying rod 110, the second drying rod 120 is magnetically attracted to the first drying rod 110, and the second drying rod 120 stops at the storage position.
