Description

Technical Field

[0001] This utility model relates to the field of toiletries technology, and in particular to a toothpaste storage rack. Background Technology

[0002] A toothpaste holder is a device used to store toothpaste, usually designed to be wall-mounted or placed on a countertop. Its purpose is to facilitate the organization and retrieval of toothpaste, while preventing it from becoming cluttered or falling over. Improved toothpaste holders better hold toothpaste in place, preventing it from slipping, and can accommodate different sizes of toothpaste, with a more stable installation.

[0003] Currently, most toothpaste holders on the market use a simple snap-fit ​​fixing structure, which is prone to problems such as the snap-fit ​​failing and the toothpaste falling out. At the same time, the clamping structure of traditional holders is mostly a rigid design, which cannot accommodate toothpaste of different diameters and lacks an anti-drop mechanism. Toothpaste can easily slip off due to accidental contact during use, resulting in waste and hygiene problems.

[0004] Therefore, there is an urgent need for a toothpaste storage rack that can conveniently store toothpaste, prevent it from falling, ensure stable installation, and accommodate toothpaste tubes of different diameters. Utility Model Content

[0005] This utility model provides a toothpaste storage rack to solve the defects of traditional toothpaste storage racks in related technologies, such as toothpaste easily falling off, unstable installation, and poor compatibility. It achieves the effects of convenient toothpaste storage and prevention of falling off, stable installation, and compatibility with toothpaste of different diameters.

[0006] This utility model provides a toothpaste storage holder, including a clamping assembly. The clamping assembly includes a first clamping arm and a second clamping arm. The first ends of the first clamping arm and the second clamping arm are connected. The second ends of the first clamping arm and the second clamping arm are spaced apart and form a downward-opening clamping groove, which can clamp toothpaste. The first or second clamping arm has a connecting structure on the side away from the clamping groove, which can fix the toothpaste holder to the object to be assembled. A locking roller is provided on the inner wall of the clamping groove. The locking roller is rotatably connected to the first clamping arm. The locking roller has an elastic pre-tightening force toward the inner wall on the opposite side. The locking roller is provided with a one-way limiting mechanism. During the process of toothpaste entering the clamping groove, the one-way limiting mechanism is in the open state, and the locking roller can roll in one direction and form rolling friction with the toothpaste; during the process of toothpaste leaving the clamping groove, the one-way limiting mechanism is in the limiting state, and the locking roller forms static friction or sliding friction with the toothpaste under the limitation of the one-way limiting mechanism.

[0007] The clamping assembly in the above structure can be composed of a first clamping arm and a second clamping arm. Since the first ends of the first and second clamping arms are connected, their second ends form downward-opening clamping grooves, providing a basic space to hold the toothpaste. The clamping assembly adapts to toothpaste of different diameters through elastic deformation, achieving a physical clamping function.

[0008] The connecting structure is located on the side of the first and second clamping arms away from the clamping groove. It uses methods such as adhesive bonding and magnetic attraction to fix the toothpaste storage rack to the object to be assembled, such as a wall or washstand, thereby achieving stable installation.

[0009] The locking roller is rotatably connected to the first clamping arm. Because the locking roller, in conjunction with the clamping assembly, possesses an elastic preload, it ensures close contact with the toothpaste surface, providing structural support for friction force switching. The one-way limiting mechanism can include a one-way transmission structure such as a ratchet or an overrunning clutch to achieve open-limit state switching. The type of friction force can be changed by varying the rotation direction of the locking roller.

[0010] The clamping assembly works in conjunction with the locking roller. The clamping groove provides a space for the toothpaste, and the locking roller adheres to the toothpaste surface with the help of elastic pre-tightening force, forming a combination of physical clamping and dynamic contact. This can effectively clamp the toothpaste and effectively avoid situations where hard contact makes it difficult to clamp the toothpaste or cause it to fall off easily.

[0011] In some examples, the locking roller is a hollow structure, and the one-way limiting mechanism is at least partially located inside the locking roller.

[0012] The above structure provides better protection for the one-way limit mechanism, preventing it from being interfered with or damaged by external factors during long-term use, thereby ensuring the normal working performance and service life of the one-way limit mechanism.

[0013] Meanwhile, placing the one-way limiting mechanism inside the locking roller makes the entire toothpaste storage rack more compact, saving space and improving space utilization.

[0014] In some examples, the locking roller includes a roller body, an assembly groove at one end of the roller body, and a rotating connecting post at the other end of the roller body, the rotating connecting post being rotatably connected to the first clamping arm; At least a portion of the one-way limiting mechanism is located in the assembly groove, with the end of the one-way limiting mechanism near the assembly groove circumferentially locked inside the roller body, and the end of the one-way limiting mechanism away from the assembly groove locked on the first clamping arm. During the process of toothpaste entering the clamping groove, the one-way limiting mechanism is in the open state, and the roller body can roll in one direction, forming rolling friction with the toothpaste; during the process of toothpaste leaving the clamping groove, the one-way limiting mechanism is in the limiting state, the roller body is locked, and forms static friction or sliding friction with the toothpaste.

[0015] The above structure ensures the stable operation of the locking roller in different usage scenarios.

[0016] When the toothpaste enters the holding slot, the roller body can roll smoothly in one direction, reducing resistance to the toothpaste and making placement easy and effortless. When the toothpaste needs to be removed or during placement, the one-way limiting mechanism quickly activates, locking the roller body and generating sufficient friction between it and the toothpaste to prevent accidental slippage. This structure not only improves ease of use but also greatly enhances the stability of the toothpaste on the toothpaste holder.

[0017] In some examples, the one-way limiting mechanism is a ratchet mechanism, which includes a first limiting member, a second limiting member, and a reset member; The first limiting member is rotatably connected to the assembly groove, and a locking connecting post is provided on the side of the first limiting member away from the assembly groove, and the locking connecting post is locked on the first clamping arm. The second limiting member is slidably disposed in the assembly groove. The second limiting member and the assembly groove are provided with mutually cooperating limiting grooves and limiting blocks in the circumferential direction. The limiting grooves and limiting blocks cooperate to restrict the relative rotation of the second limiting member and the roller body. The first limiting member is provided with a first one-way ratchet, the second limiting member is provided with a second one-way ratchet that engages with the first one-way ratchet, and the reset member is provided between the second limiting member and the bottom of the assembly groove to provide the second one-way ratchet with the contact force with the first one-way ratchet. During the process of toothpaste entering the clamping groove, the second one-way ratchet can rotate relative to the first one-way ratchet, so that the roller body and the second limiting member can roll in one direction and form rolling friction with the toothpaste; during the process of toothpaste leaving the clamping groove, the first one-way ratchet restricts the rotation of the second one-way ratchet, so that the roller body and the second limiting member are locked and form static friction or sliding friction with the toothpaste.

[0018] The aforementioned ratchet mechanism's one-way limiting mechanism utilizes the interlocking one-way ratchet teeth on the first and second limiting members during operation. Combined with the reset member, this achieves one-way opening movement and reverse limiting locking. When toothpaste needs to be removed, greater force can be applied to detach it from the toothpaste holder.

[0019] When the toothpaste enters the clamping groove, the second one-way ratchet can rotate smoothly relative to the first one-way ratchet, allowing the roller body and the second limiting member to roll in one direction, thereby forming a rolling friction force with the toothpaste, making the toothpaste placement process easy and unobstructed.

[0020] When the toothpaste comes out of the clamping groove, the first one-way ratchet will quickly restrict the rotation of the second one-way ratchet, so that the roller body and the second limiting part are locked instantly, thereby forming static friction or sliding friction with the toothpaste, effectively preventing the toothpaste from accidentally slipping off.

[0021] In some examples, a clearance area is provided in the assembly slot, and the first limiting member can enter the clearance area under the action of external force so that the first limiting member is completely inside the assembly slot; Alternatively, after the first limiting member moves at least partially into the assembly slot, the locking connecting post can disengage from the locked state.

[0022] The above structure greatly facilitates the installation, debugging, and possible maintenance and replacement of the one-way limit mechanism.

[0023] During installation, when the first limiting component needs to be installed into the assembly slot, external force can cause it to move into the clearance area. This ensures the first limiting component is fully positioned within the assembly slot, avoiding installation difficulties caused by insufficient space and improving installation efficiency. During the commissioning phase, if the unidirectional limiting mechanism is found to be malfunctioning and requires adjustment, the clearance area also allows operators to more easily manipulate the first limiting component without the need for complex disassembly.

[0024] In some examples, the rotating connecting post is rotatably connected to the first clamping arm, and the first clamping arm is provided with a first ear plate structure adapted to the rotating connecting post. The first ear plate structure is provided with a rotating connecting hole adapted to the rotating connecting post. The locking connecting post is locked to the first clamping arm. The first clamping arm is provided with a second ear plate structure that is adapted to the locking connecting post. The second ear plate structure has a locking connecting hole that is adapted to the locking connecting post. When the locking connecting post is connected to the locking connecting hole, the first limiting member and the first clamping arm are locked relative to each other. After the locking connecting post is disengaged from the locking connecting hole, the first limiting member and the first clamping arm are unlocked relative to each other.

[0025] The connection method achieved through the ear plate structure and connecting post provides convenience for the assembly and disassembly of the toothpaste storage holder.

[0026] During assembly, the rotating connecting post is accurately inserted into the rotating connecting hole of the first ear plate structure to achieve a rotating connection between the locking roller and the first clamping arm. The operation is simple and the connection is stable. The locking connecting post and the locking connecting hole of the second ear plate structure cooperate to ensure the relative locking of the positions of the first limiting member and the first clamping arm, ensuring that the one-way limiting mechanism can function stably.

[0027] When the toothpaste holder needs repair, cleaning, or adjustment, simply disengage the locking pin from the locking hole to unlock the first limiting member and the first clamping arm, facilitating operation of the relevant components. Afterwards, reinserting the locking pin into the locking hole quickly restores the toothpaste holder to its normal working state.

[0028] In some examples, the locking connection hole is shaped like a polygon, a sector, a star, a plum blossom, or an irregular shape, and the outer periphery of the locking connection post is adapted to the shape of the locking connection hole.

[0029] The aforementioned structure, employing specially shaped locking connection holes and matching locking connection posts, offers numerous significant advantages. For example, unique shapes such as polygons, sectors, stars, plum blossoms, and irregular shapes, compared to the common circular shape, greatly increase the contact area and friction between the locking connection post and the locking connection hole. In the locked state, the increased friction effectively prevents the locking connection post from accidentally rotating or loosening within the locking connection hole, thus ensuring a more stable and reliable relative locking between the first limiting member and the first clamping arm. Even under external impact or prolonged use, it maintains a stable connection state, preventing easy connection failure and providing a solid guarantee for the normal operation of the unidirectional limiting mechanism.

[0030] In some examples, the second clamping arm includes a clamping part and an assembly part connected to each other, the clamping part is connected to a first end of the first clamping arm, and a clamping groove is formed between the clamping part and the first clamping arm; The connecting structure is located on the side of the assembly part away from the clamping groove.

[0031] The above describes a structure in which the second clamping arm is designed as an interconnected clamping part and an assembly part. Specifically, the clamping part is connected to the first end of the first clamping arm and together they form a clamping groove, which can stably clamp the toothpaste and provide a reliable placement space for the toothpaste. The clamping part can be adapted to toothpaste of different sizes and shapes through reasonable size and shape design, ensuring that the toothpaste is stably placed on the toothpaste storage rack and is not easy to shake or fall off.

[0032] The assembly section features a connecting structure on the side away from the clamping slot, facilitating the connection of the toothpaste organizer to other components or the installation environment. This well-designed connection structure allows for easy mounting of the toothpaste organizer to various locations such as walls and cabinets, meeting diverse user installation needs.

[0033] In some examples, the clamping part and the assembly part are spaced apart, and the second ends of the clamping part and the assembly part are connected, so that the cup wall of the toothpaste cup can be supported between the clamping part and the assembly part, so that the toothpaste holder can store the toothpaste cup.

[0034] The aforementioned structure adds the function of storing toothpaste cups to the toothpaste storage holder, greatly improving its practicality and space utilization. In daily use, toothpaste cups are usually kept close to toothpaste, and previously, separate placement was required, which not only took up space but could also affect the tidiness of the washing environment due to clutter. However, the toothpaste storage holder provided in this embodiment uses the space between the clamping part and the assembly part to support the cup wall of the toothpaste cup, storing the toothpaste and toothpaste cup together, making the placement of toiletries more organized.

[0035] In some examples, the second end of the first clamping arm protrudes upward on the side away from the clamping groove to form a toothed cup bearing structure, and the connection between the clamping part and the assembly part and the toothed cup bearing structure can respectively bear the two opposite cup walls of the toothed cup.

[0036] The aforementioned structure further optimizes the toothpaste holder's function in storing toothpaste cups, providing more stable and comprehensive support. The toothpaste cup support structure protrudes upwards, engaging with the connection points of the clamping and mounting parts to support the cup wall from two different directions. This dual-support structure greatly enhances the stability of the toothpaste holder when placed on the toothpaste holder, ensuring stability even when the cup contains a certain amount of water and preventing it from tipping over.

[0037] In some examples, the first clamping arm also includes a hook portion with at least one hook slot, each hook slot being capable of hooking a toothbrush structure.

[0038] From a space utilization perspective, the above structure makes full use of the existing toothpaste storage rack, providing a dedicated place for toothbrushes without taking up too much extra space. Previously, toothbrushes were often left haphazardly on the washbasin, which not only looked messy but also easily bumped into other items. This toothpaste storage rack, with its hanging slot design, neatly stores toothbrushes, making the washbasin surface more organized and greatly improving space utilization efficiency.

[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0043] The following is combined with Figures 1-6 The present invention describes a toothpaste storage holder, including a clamping assembly 100. The clamping assembly 100 includes a first clamping arm 110 and a second clamping arm 120. The first ends of the first clamping arm 110 and the second clamping arm 120 are connected. The second ends of the first clamping arm 110 and the second clamping arm 120 are spaced apart and form a downward-opening clamping groove 131, which can clamp toothpaste. Reference Figures 1 to 4 The first clamping arm 110 or the second clamping arm 120 has a connecting structure 141 on the side away from the clamping groove 131. The connecting structure 141 can fix the toothpaste holder to the object to be assembled. A locking roller 200 is provided on the inner wall of the clamping groove 131. The locking roller 200 is rotatably connected to the first clamping arm 110. The locking roller 200 has an elastic pre-tightening force toward the opposite inner wall. The locking roller 200 is provided with a one-way limiting mechanism 300. During the process of toothpaste entering the clamping groove 131, the one-way limiting mechanism 300 is in the open state, and the locking roller 200 can roll in one direction and form rolling friction with the toothpaste; during the process of toothpaste leaving the clamping groove 131, the one-way limiting mechanism 300 is in the limiting state, and the locking roller 200 forms static friction or sliding friction with the toothpaste under the limitation of the one-way limiting mechanism 300.

[0044] The clamping assembly 100 in the above structure can be composed of a first clamping arm 110 and a second clamping arm 120. Since the first ends of the first clamping arm 110 and the second clamping arm 120 are connected, and the second ends are spaced apart to form a downward-opening clamping groove 131, it provides a basic space for accommodating toothpaste. The clamping assembly 100 adapts to toothpaste of different diameters through elastic deformation to achieve a physical clamping function.

[0045] The connecting structure 141 is located on the side of the first clamping arm 110 and the second clamping arm 120 away from the clamping groove 131. It uses methods such as adhesive bonding and magnetic attraction to fix the toothpaste storage rack to the object to be assembled, such as a wall or a washstand, thereby solving the problem of installation stability.

[0046] The locking roller 200 is rotatably connected to the first clamping arm 110. Since the locking roller 200, when in conjunction with the clamping assembly 100, possesses an elastic preload, it ensures close contact with the toothpaste surface, providing structural support for friction force switching. The one-way limiting mechanism 300 may include a one-way transmission structure such as a ratchet or an overrunning clutch to achieve open-limit state switching. The type of friction force can be changed by varying the rotation direction of the locking roller 200.

[0047] The clamping assembly 100 works in conjunction with the locking roller 200. The clamping groove 131 provides a receiving space. The locking roller 200 adheres to the toothpaste surface with the help of elastic pre-tightening force, forming a combination of physical clamping and dynamic contact. This can effectively clamp the toothpaste and effectively avoid the situation where hard contact causes the toothpaste to be difficult to clamp or easily fall off.

[0048] The locking roller 200 cooperates with the one-way limiting mechanism 300, which ensures that the roller only rolls in the toothpaste insertion direction. When inserted, the roller rotates with the toothpaste, generating rolling friction; when removed, the roller locks, generating static friction or sliding friction, achieving the effect of easy insertion and preventing it from falling out.

[0049] The connecting structure 141 complements the overall component. The connecting structure 141 can fix the entire toothpaste storage holder, ensure the stability of the clamping component 100 and the locking roller 200, prevent the toothpaste from falling off due to the displacement of the toothpaste storage holder, and improve the overall reliability of use.

[0050] This disclosure utilizes a one-way limiting mechanism 300 to control the movement of the roller, enabling convenient insertion, secure clamping, and controllable removal of toothpaste. During insertion, the mechanism opens, allowing the roller to roll with the toothpaste, reducing friction and facilitating operation. During clamping, the mechanism locks to ensure static contact between the roller and the toothpaste surface, increasing friction to prevent it from falling off. During removal, static friction must be overcome to maintain the locked state, ensuring a stable and reliable removal process and effectively preventing accidental drops.

[0051] This disclosure utilizes a combination design of clamping component 100 providing space, locking roller 200 in dynamic contact, one-way limiting mechanism 300 controlling the type of friction force, and connecting structure 141 fixing the position. This solution successfully achieves convenient toothpaste storage and prevents it from falling out, effectively solving the contradiction of traditional storage racks where toothpaste is difficult to put in or easy to fall out. Furthermore, the elastic pre-tightening design can accommodate toothpaste of different diameters, while the one-way limiting mechanism 300 significantly reduces the difficulty of operation. The overall structure is compact, not only improving the user experience but also saving space on the sink.

[0052] In actual use, when toothpaste needs to be placed into the clamping slot 131 of the toothpaste holder, the locking roller 200 can roll unidirectionally in the direction the toothpaste enters because the one-way limiting mechanism 300 is in the open state. At this time, the locking roller 200 and the toothpaste form a rolling friction force, which is small and will not cause significant obstruction to the placement of the toothpaste, making it easy for users to put the toothpaste into the clamping slot 131. When the user removes the toothpaste from the clamping slot 131, the one-way limiting mechanism 300 will quickly switch to the limiting state. Under the restriction of the one-way limiting mechanism 300, the locking roller 200 can no longer roll freely, but forms a static friction force or sliding friction force with the toothpaste. This friction force can effectively prevent the toothpaste from easily sliding out of the clamping slot 131, ensuring the stable placement of the toothpaste on the toothpaste holder and avoiding waste and inconvenience caused by accidental toothpaste falling.

[0053] Furthermore, with the one-way limiting mechanism 300 in the open state, the roller can rotate freely. When toothpaste is inserted, the roller is driven to rotate by the frictional force of the toothpaste surface. Since the rolling friction coefficient (approximately 0.01-0.05) is significantly lower than the static friction coefficient (approximately 0.3-0.5), the resistance encountered during toothpaste insertion is small, thus achieving an easy insertion effect.

[0054] When the one-way limit mechanism is locked at 300°, the roller cannot rotate. When the toothpaste is pulled down by gravity, the roller remains relatively stationary with respect to the toothpaste surface, relying on static friction (F=μN, where N is the preload) to resist the toothpaste's gravity (G=mg). By rationally designing the elastic preload, μN>G is ensured, thus allowing the toothpaste to hang stably and achieving the "anti-fall" effect.

[0055] The locking roller 200 has an elastic preload. When toothpaste of different sizes is inserted, the roller is compressed and deformed, and the preload is adaptively adjusted accordingly. This mechanism ensures that the contact pressure between the roller and the toothpaste surface remains stable, thereby maintaining a consistent frictional effect and achieving wide compatibility with different toothpaste sizes. Additionally, the toothpaste holder provided in this embodiment also functions as a holder for storing toothbrush cups and toothbrushes.

[0056] The connection structure 141 described above may include at least one of the following: adhesive structure, magnetic structure, negative pressure adsorption structure, snap-fit ​​structure, bolt fixing structure, hanging structure, and clamp structure.

[0057] In practical applications, users can choose a suitable connection structure 141 to fix the toothpaste holder to the object to be assembled, depending on different usage scenarios and needs. For example, if the surface of the object to be assembled is smooth and flat, an adhesive structure is a good choice, as it can firmly stick the toothpaste holder to the surface of the object with adhesive, which is simple to operate and low in cost. When the object to be assembled is magnetic or can have magnetic components attached, a magnetic structure can play its advantage, using magnetic force to attract the toothpaste holder to the object, making it easy to disassemble and adjust its position. A negative pressure adsorption structure is suitable for objects with relatively smooth and flat surfaces. By generating negative pressure, the toothpaste holder is tightly adsorbed to the surface of the object, providing strong stability. Snap-fit ​​structures, bolt-fixing structures, hanging structures, and clamp structures are suitable for objects of different shapes and materials to be assembled. Each of these structures has a unique fixing method and characteristics, which can meet diverse installation needs.

[0058] With these diverse connection structures 141, the toothpaste storage rack can be flexibly installed in various locations in the bathroom, such as on the wall, cabinet door, and next to the mirror, making full use of space and creating a clean and orderly washing environment for users.

[0059] The one-way limiting mechanism 300 can be an existing ratchet and ratchet mechanism, with one of the ratchet and ratchet located on the locking roller 200 and the other on the first clamping arm 110. When using an existing ratchet and ratchet mechanism as the one-way limiting mechanism 300, its working principle can well meet the needs of the toothpaste storage holder. In the ratchet and ratchet structure, the ratchet usually has a specific tooth shape, and the ratchet cooperates with the ratchet. During the process of toothpaste entering the clamping groove 131, the ratchet and ratchet are in a relatively free state. The ratchet can rotate unidirectionally in the direction in which the toothpaste enters. At this time, just like the unidirectional rolling of the locking roller 200, a small rolling friction force is formed between it and the toothpaste, allowing the toothpaste to be put in smoothly. When the toothpaste is about to leave the clamping groove 131, the ratchet will quickly engage in the tooth groove of the ratchet, forming a limit, preventing the ratchet from rotating in the opposite direction, and thus preventing the locking roller 200 from rolling freely. Static friction or sliding friction force is formed between it and the toothpaste, effectively preventing the toothpaste from sliding out. The ratchet mechanism is simple and mature in structure, and relatively low in cost. Applying it to toothpaste storage racks can ensure the functionality of the toothpaste storage rack while controlling production costs, improving the product's cost-effectiveness, and making it easier to promote and popularize in the market. It provides consumers with a practical and economical solution for storing toiletries.

[0060] Furthermore, the one-way limit mechanism 300 includes at least one of the following: ratchet mechanism, overrunning clutch, one-way bearing, wedge-type one-way clutch, friction-type one-way limiter, spring pin mechanism, rack and pinion one-way locking mechanism, cam-type one-way limiter, rocker arm-type one-way limiter, hydraulic one-way valve, and magnetic one-way limiter.

[0061] In addition to the ratchet mechanism mentioned above, the one-way limiting mechanism 300, when employing an overrunning clutch, can also meet the usage requirements of the toothpaste storage holder. The overrunning clutch has a unique structure; it can rotate freely in one direction while locking in the other. When the toothpaste enters the clamping groove 131, the overrunning clutch is in a free-rotating state, and the locking roller 200 can roll unidirectionally in the direction the toothpaste enters, creating a small rolling friction force with the toothpaste, facilitating toothpaste placement. When the toothpaste is about to leave the clamping groove 131, the overrunning clutch quickly switches to a locked state, preventing the locking roller 200 from rolling in the opposite direction, creating static or sliding friction between the locking roller 200 and the toothpaste, preventing the toothpaste from slipping out.

[0062] If the one-way limiting mechanism 300 uses a one-way bearing, during the process of toothpaste entering the clamping groove 131, the one-way bearing allows the locking roller 200 to rotate in one direction. At this time, the rolling friction is small, making it easy for the toothpaste to be inserted. However, when the toothpaste is extracted, the one-way bearing restricts the locking roller 200 from rotating in the opposite direction, generating greater friction to prevent the toothpaste from sliding out.

[0063] When the wedge-type one-way clutch is used as a one-way limiting mechanism 300, the wedge is in a sliding state under a specific structure when toothpaste is introduced, allowing the locking roller 200 to roll in one direction. When the toothpaste needs to be removed, the wedge engages in the corresponding position, restricting the rotation of the locking roller 200 and achieving stable toothpaste storage.

[0064] The friction-type one-way limit switch utilizes the principle of friction. When toothpaste is introduced, the friction force is relatively small, allowing the locking roller 200 to roll. When toothpaste is withdrawn, the friction force increases, preventing the locking roller 200 from rolling and thus preventing the toothpaste from slipping out.

[0065] When toothpaste is introduced, the spring pin is in a movable state, not affecting the unidirectional rotation of the locking roller 200. When toothpaste is extracted, the spring pin pops out and locks the relevant structure, restricting the rotation of the locking roller 200 and ensuring the stability of the toothpaste.

[0066] When toothpaste is introduced, the rack and related components of the rack and pinion locking mechanism are in a state of relative motion, allowing the locking roller 200 to rotate. When toothpaste is extracted, the rack and components lock, restricting the rotation of the locking roller 200 and preventing the toothpaste from slipping out.

[0067] When toothpaste is introduced, the cam-type one-way limiter uses a special cam shape to allow the locking roller 200 to rotate in one direction. When toothpaste is removed, the cam shape changes, limiting the rotation of the locking roller 200 and ensuring stable toothpaste storage.

[0068] When toothpaste is introduced, the swing arm of the one-way limiting device is in a swingable state, which does not affect the rotation of the locking roller 200. When toothpaste is extracted, the swing arm swings to a specific position to limit the rotation of the locking roller 200 and prevent the toothpaste from slipping out.

[0069] The hydraulic check valve utilizes hydraulic principles. When toothpaste is introduced, hydraulic pressure flows normally, allowing the locking roller 200 to rotate. When toothpaste is extracted, the hydraulic pressure stops the flow, restricting the rotation of the locking roller 200 and ensuring stable toothpaste extraction.

[0070] When toothpaste is inserted, the magnetic unidirectional limiter exerts minimal magnetic force, which does not affect the unidirectional rotation of the locking roller 200. When toothpaste is removed, the magnetic force increases, restricting the rotation of the locking roller 200 and preventing the toothpaste from slipping out. These different types of unidirectional limit mechanisms 300 can provide stable and reliable unidirectional limit functions for the toothpaste holder, meeting the usage requirements of different scenarios and needs.

[0071] Reference Figures 1 to 4 In some examples, the locking roller 200 is a hollow structure, and the one-way limiting mechanism 300 is at least partially disposed within the locking roller 200.

[0072] The above structure provides better protection for the one-way limit mechanism 300, preventing it from being interfered with or damaged by external factors during long-term use, thereby ensuring the normal working performance and service life of the one-way limit mechanism 300.

[0073] Meanwhile, the one-way limiting mechanism 300 is placed inside the locking roller 200, which makes the structure of the entire toothpaste storage rack more compact, saves space, and improves space utilization.

[0074] Moreover, the internal design enhances the connection stability between the one-way limiting mechanism 300 and the locking roller 200 to a certain extent, making their cooperation more seamless and enabling more precise switching between one-way limiting and rolling functions, thus further improving the usability and stability of the toothpaste storage holder.

[0075] Reference Figures 1 to 4 In some examples, the locking roller 200 includes a roller body 210, an assembly groove 211 opened at one end of the roller body 210, and a rotating connecting post 213 disposed at the other end of the roller body 210. The rotating connecting post 213 is rotatably connected to the first clamping arm 110. At least a portion of the one-way limiting mechanism 300 is located in the assembly groove 211. The end of the one-way limiting mechanism 300 near the assembly groove 211 is circumferentially locked in the roller body 210, and the end of the one-way limiting mechanism 300 away from the assembly groove 211 is locked on the first clamping arm 110. During the process of toothpaste entering the clamping groove 131, the one-way limiting mechanism 300 is in an open state, the roller body 210 can roll in one direction and form rolling friction with the toothpaste; during the process of toothpaste leaving the clamping groove 131, the one-way limiting mechanism 300 is in a limiting state, the roller body 210 is locked, and forms static friction or sliding friction with the toothpaste.

[0076] The aforementioned sophisticated structure ensures the stable operation of the locking roller 200 under various usage scenarios. When toothpaste enters the clamping slot 131, the roller body 210 can smoothly roll in one direction, reducing resistance to the toothpaste and making placement easy and effortless. When the toothpaste needs to be removed, the one-way limiting mechanism 300 quickly activates, locking the roller body 210 and generating sufficient friction between it and the toothpaste to prevent accidental slippage. This structure not only improves ease of use but also greatly enhances the stability of the toothpaste on the toothpaste holder.

[0077] Furthermore, the roller body 210 and the first clamping arm 110 are rotatably connected via a rotating connecting post 213, a simple and reliable structure that ensures the roller body 210 can rotate flexibly. Simultaneously, the locking connection between the one-way limiting mechanism 300 and the roller body 210 and the first clamping arm 110 further enhances the overall structural stability, making the toothpaste holder less prone to loosening or damage during long-term use, providing users with a more durable and stable user experience.

[0078] Reference Figures 1 to 4 In some examples, the one-way limiting mechanism 300 is a ratchet mechanism, which includes a first limiting member 310, a second limiting member 320, and a reset member 330. The first limiting member 310 is rotatably connected to the assembly groove 211. A locking connecting post 311 is provided on the side of the first limiting member 310 away from the assembly groove 211. The locking connecting post 311 is locked onto the first clamping arm 110. The second limiting member 320 is slidably disposed in the assembly groove 211. The second limiting member 320 and the assembly groove 211 are provided with mutually cooperating limiting grooves 215 and limiting blocks 340 in the circumferential direction. The limiting grooves 215 and limiting blocks 340 cooperate to restrict the relative rotation of the second limiting member 320 and the roller body 210. The first limiting member 310 is provided with a first one-way ratchet 312, the second limiting member 320 is provided with a second one-way ratchet 321 that engages with the first one-way ratchet 312, and the reset member 330 is provided between the second limiting member 320 and the bottom of the assembly groove 211 to provide the second one-way ratchet 321 with a contact force with the first one-way ratchet 312; During the process of toothpaste entering the clamping groove 131, the second one-way ratchet 321 can rotate relative to the first one-way ratchet 312, so that the roller body 210 and the second limiting member 320 can roll in one direction and form rolling friction with the toothpaste; during the process of toothpaste leaving the clamping groove 131, the first one-way ratchet 312 restricts the rotation of the second one-way ratchet 321, so that the roller body 210 and the second limiting member 320 are locked and form static friction or sliding friction with the toothpaste.

[0079] The unidirectional limiting mechanism 300 of the aforementioned ratchet mechanism utilizes the interlocking unidirectional ratchet teeth on the first limiting member 310 and the second limiting member 320 during operation. Combined with the reset member 330, it achieves unidirectional opening and closing, and reverse limiting and locking. When toothpaste needs to be removed, greater force can be applied to detach it from the toothpaste holder.

[0080] When the toothpaste enters the clamping groove 131, the second one-way ratchet 321 can rotate smoothly relative to the first one-way ratchet 312, so that the roller body 210 and the second limiting member 320 can roll in one direction, thereby forming a rolling friction force with the toothpaste, making the toothpaste placement process easy and unobstructed.

[0081] When the toothpaste is released from the clamping groove 131, the first one-way ratchet 312 will quickly restrict the rotation of the second one-way ratchet 321, so that the roller body 210 and the second limiting member 320 are locked instantly, thereby forming static friction or sliding friction with the toothpaste, effectively preventing the toothpaste from accidentally slipping off.

[0082] The reset component 330 plays a crucial role between the second limiting component 320 and the bottom of the assembly groove 211, continuously providing a contact force between the second one-way ratchet 321 and the first one-way ratchet 312, ensuring that the two always maintain a good pinching state, and guaranteeing the stability and reliability of the one-way limiting mechanism 300. This structure is not only compact but also easy to operate, and can accurately realize the functional switching between one-way limiting and rolling, greatly improving the performance and user experience of the toothpaste holder.

[0083] Furthermore, the reset component 330 is at least one of the following: spring, coil spring, spring sheet, pneumatic rod, hydraulic damper, torsion spring, magnetic reset structure, elastic rope or rubber band, eccentric wheel structure, shape memory alloy, gravity reset mechanism, and cam mechanism.

[0084] Depending on different usage requirements and cost considerations, a suitable type of reset component 330 can be selected. By using different reset components 330, the structure of other components can also be adjusted accordingly. Springs, as a common reset component 330, have advantages such as simple structure, low cost, and stable reset effect. They can provide a continuous and stable contact force for the second one-way ratchet 321, ensuring the normal operation of the one-way limiting mechanism 300. Coil springs have a large elastic deformation capacity and can store a large amount of elastic potential energy in a small space, making them suitable for applications requiring high reset force and with limited space. Spring sheets are characterized by their thinness, good elasticity, and fast response speed, providing a large reset force instantly, allowing the one-way limiting mechanism 300 to quickly return to its initial state.

[0085] Pneumatic rods and hydraulic dampers provide cushioning and shock absorption, making the movement of the second one-way ratchet 321 smoother during the reset process, reducing impact and noise, and improving the user comfort of the toothpaste holder. Torsion springs provide the reset force in the rotational direction and are suitable for one-way limit mechanisms 300 that require rotational reset. Magnetic reset structures utilize magnetic force for reset, offering advantages such as no contact, no wear, and long lifespan, but at a relatively high cost. Elastic ropes or rubber bands are low-cost and easy to install, but their elasticity may decrease over long-term use.

[0086] The eccentric wheel structure changes the position of the second limiting member 320 by rotating the eccentric wheel, thereby achieving the reset function. It has advantages such as unique structure and adjustable reset force. Shape memory alloys have a shape memory effect, allowing them to recover their original shape after being deformed by external force, providing a reliable reset force for the unidirectional limiting mechanism 300. However, they are costly and have certain requirements for the operating environment. The gravity reset mechanism uses gravity to return the second limiting member 320 to its initial position. It has a simple structure, but the reset force is greatly affected by gravity, making it suitable for specific application scenarios. The cam mechanism uses the rotation of the cam to drive the second limiting member 320 to achieve the reset function, offering advantages such as compact structure and high reset accuracy.

[0087] By selecting different types of reset components 330, the performance of the one-way limit mechanism 300 can be optimized according to the specific design requirements and usage environment of the toothpaste storage holder, thereby improving the stability and reliability of the toothpaste storage holder and providing users with a better user experience.

[0088] Reference Figures 1 to 4 In some examples, an avoidance area 214 is provided in the assembly slot 211, and the first limiting member 310 can enter the avoidance area 214 under the action of external force so that the first limiting member 310 is completely in the assembly slot 211. Alternatively, after the first limiting member 310 moves at least partially into the assembly groove 211, the locking connecting post 311 can disengage from the locked state.

[0089] The aforementioned clearance area 214 greatly facilitates the installation, commissioning, and possible maintenance and replacement of the one-way limiting mechanism 300. During installation, when the first limiting member 310 needs to be installed into the assembly slot 211, external force can cause the first limiting member 310 to enter the clearance area 214. This ensures the first limiting member 310 is completely and smoothly positioned within the assembly slot 211, avoiding installation difficulties caused by insufficient space and improving installation efficiency. During commissioning, if the working condition of the one-way limiting mechanism 300 is found to be unsatisfactory and adjustments are needed, the clearance area 214 also allows operators to more easily manipulate the first limiting member 310 without a complex disassembly process.

[0090] Furthermore, after prolonged use, if the one-way limiting mechanism 300 becomes damaged and requires repair or replacement, the first limiting member 310 can be easily removed from the assembly slot 211 by moving at least partially towards the assembly slot 211, thereby disengaging the locking connecting post 311. This allows for repair or replacement of the component, and then reinstallation, significantly reducing repair difficulty and cost. Simultaneously, this structure enhances the overall maintainability of the toothpaste holder, extends its service life, and provides users with a more durable and stable operating guarantee.

[0091] Reference Figures 1 to 4 In some examples, the rotating connecting post 213 is rotatably connected to the first clamping arm 110. The first clamping arm 110 is provided with a first ear plate structure 111 adapted to the rotating connecting post 213. The first ear plate structure 111 is provided with a rotating connecting hole 112, which is adapted to the rotating connecting post 213. The locking connecting post 311 is locked to the first clamping arm 110. The first clamping arm 110 is provided with a second ear plate structure 113 adapted to the locking connecting post 311. The second ear plate structure 113 is provided with a locking connecting hole 114. The locking connecting hole 114 is adapted to the locking connecting post 311. When the locking connecting post 311 is connected to the locking connecting hole 114, the positions of the first limiting member 310 and the first clamping arm 110 are locked relative to each other. After the locking connecting post 311 is disengaged from the locking connecting hole 114, the positions of the first limiting member 310 and the first clamping arm 110 are unlocked relative to each other.

[0092] The connection method achieved through the ear plate structure and connecting post described above facilitates the assembly and disassembly of the toothpaste holder. During assembly, accurately inserting the rotating connecting post 213 into the rotating connecting hole 112 of the first ear plate structure 111 achieves a rotatable connection between the locking roller 200 and the first clamping arm 110, which is simple to operate and provides a stable connection. The engagement of the locking connecting post 311 with the locking connecting hole 114 of the second ear plate structure 113 ensures the relative locking of the positions of the first limiting member 310 and the first clamping arm 110, guaranteeing the stable functioning of the one-way limiting mechanism 300.

[0093] When the toothpaste holder needs repair, cleaning, or adjustment, simply disengage the locking connecting pin 311 from the locking connecting hole 114 to unlock the first limiting member 310 from the first clamping arm 110, facilitating operation of the relevant components. Afterwards, reinserting the locking connecting pin 311 into the locking connecting hole 114 quickly restores the toothpaste holder to its normal working state.

[0094] The aforementioned connection structure not only improves the assembly efficiency of the toothpaste holder but also enhances its maintainability, making it easier for users to manage and maintain the toothpaste holder during use, further improving the product's practicality and user experience. At the same time, this precise fitting structure ensures the connection accuracy between components, reducing noise and wear caused by loose connections and extending the toothpaste holder's lifespan.

[0095] Reference Figures 1 to 4 In some examples, the shape of the locking connection hole 114 is one of polygon, sector, star, plum blossom, or irregular shape, and the outer peripheral shape of the locking connection post 311 is adapted to the shape of the locking connection hole 114.

[0096] The aforementioned structure, employing a specially shaped locking connection hole 114 and a matching locking connection post 311, offers numerous significant advantages. For instance, unique shapes such as polygons, sectors, stars, plum blossoms, and irregular shapes, compared to the common circular shape, greatly increase the contact area and friction between the locking connection post 311 and the locking connection hole 114. In the locked state, the increased friction effectively prevents the locking connection post 311 from accidentally rotating or loosening within the locking connection hole 114, thereby ensuring a more stable and reliable relative locking between the first limiting member 310 and the first clamping arm 110. Even under external impact or prolonged use, it maintains a stable connection state, preventing easy connection failure and providing a solid guarantee for the normal operation of the unidirectional limiting mechanism 300.

[0097] Furthermore, these special shapes also provide a certain degree of protection against incorrect assembly. Because each shape has its unique structure and characteristics, during assembly, the locking connecting post 311 can only be smoothly inserted and locked in place when its shape perfectly matches the locking connecting hole 114. This avoids connection errors caused by misassembling parts of different specifications or types, improving assembly accuracy and efficiency. Operators can quickly and accurately assemble the components, reducing the time and effort wasted on repeated adjustments and corrections, further enhancing the production efficiency of the toothpaste holder.

[0098] The specially shaped locking holes 114 and locking pins 311 are designed with different user habits and needs in mind. For example, for users with less strength or less finesse, the specially shaped locking holes 114 and locking pins 311 provide a better feel. When inserting and removing the locking pins 311, the specially shaped edges and corners provide clearer feedback, making it easier for users to control the force and direction of the operation, thus making assembly and disassembly easier.

[0099] It should be noted that the shape of the locking connection hole 114 can also be a circular or other rotatable shape. The corresponding locking connection post 311 and the locking connection hole 114 need to be fitted with a locking component for auxiliary locking, or a damping component to increase the friction between the two.

[0100] Specifically, when the locking connection hole 114 adopts a rotatable shape such as a circle, although it does not inherently possess the self-locking characteristics of special shapes such as polygons, this problem can be effectively solved by setting a locking element for auxiliary locking. The locking element can be a simple pin, buckle, or other structure. After the locking connection pin 311 is inserted into the locking connection hole 114, the locking element is inserted into the corresponding position to prevent the locking connection pin 311 from rotating within the locking connection hole 114, thereby ensuring a stable and reliable relative locking between the first limiting member 310 and the first clamping arm 110. This auxiliary locking method has a simple structure and is easy to operate. When locking and unlocking are required, only a simple operation of the locking element is needed to complete the task, without adding excessive assembly and disassembly difficulty.

[0101] Alternatively, adding a damping element to increase the friction between the two is also a feasible solution. The damping element can be made of elastic materials such as rubber pads or silicone sleeves, installed between the locking connecting post 311 and the locking connecting hole 114. The friction generated by its elastic deformation prevents the rotation of the locking connecting post 311. This structure not only achieves a locking function to a certain extent but also acts as a buffer and shock absorber, reducing loosening and damage caused by external impacts. During assembly, simply insert the locking connecting post 311 with the damping element into the locking connecting hole 114; no additional complicated operations are required. During disassembly, the locking connecting post 311 can be easily pulled out, facilitating maintenance, cleaning, or adjustment of the toothpaste holder.

[0102] Reference Figures 1 to 4 In some examples, the second clamping arm 120 includes a clamping portion 130 and an assembly portion 140 connected to each other. The clamping portion 130 is connected to the first end of the first clamping arm 110, and a clamping groove 131 is formed between the clamping portion 130 and the first clamping arm 110. The connecting structure 141 is provided on the side of the assembly portion 140 away from the clamping groove 131.

[0103] The above structure describes a design in which the second clamping arm 120 is designed as an interconnected clamping portion 130 and an assembly portion 140. Specifically, the clamping portion 130 is connected to the first end of the first clamping arm 110 and together they form a clamping groove 131, which can stably clamp the toothpaste and provide a reliable placement space for the toothpaste. The clamping portion 130 can be adapted to toothpaste of different sizes and shapes through reasonable size and shape structure, ensuring that the toothpaste is stably placed on the toothpaste storage rack and is not easy to shake or fall off.

[0104] A connecting structure 141 is provided on the side of the assembly part 140 away from the clamping groove 131, facilitating the connection of the entire toothpaste storage rack with other components or the installation environment. Through a well-designed connecting structure, the toothpaste storage rack can be easily fixed to different locations such as walls and cabinets, meeting diverse user installation needs. For example, the connecting structure 141 can be designed in various forms such as hook type, suction cup type, and screw fixing type, allowing users to choose the most suitable installation method according to their actual situation (a more detailed description of the connecting structure 141 is provided above and will not be repeated here).

[0105] This structure makes the toothpaste holder more modular and rational. The clamping part 130 focuses on holding the toothpaste, while the assembly part 140 is responsible for connecting to the outside. Each part has a clear function and does not interfere with each other. During the manufacturing process, the clamping part 130 and the assembly part 140 can be optimized separately to improve production efficiency and product quality. At the same time, with the components detachable, if a part is damaged or needs upgrading, it can be easily replaced or improved individually, reducing maintenance costs and difficulty.

[0106] Reference Figures 1 to 4 In some examples, the clamping part 130 and the assembly part 140 are spaced apart, and the second ends of the clamping part 130 and the assembly part 140 are connected, so that the cup wall of the toothpaste cup can be supported between the clamping part 130 and the assembly part 140, so that the toothpaste holder can store the toothpaste cup.

[0107] The aforementioned structure significantly improves its practicality and space utilization. In daily use, toothbrush cups are usually kept close to toothpaste, and previously, separate placement was required, which not only took up space but could also affect the tidiness of the washing environment due to clutter. However, the toothpaste storage rack provided in this disclosure, through the space between the clamping part 130 and the assembly part 140, utilizes the space between the two to support the cup wall of the toothpaste, storing the toothpaste and toothbrush cup together, making the placement of toiletries more organized.

[0108] In terms of structural stability, the second ends of the clamping part 130 and the assembly part 140 are securely connected, providing reliable support for the toothbrush cup. This connection method ensures that the toothbrush cup will not easily wobble or fall when placed on the toothpaste holder, and it remains stable even under slight impact. Moreover, this structure fully considers the size differences of toothbrush cups of different specifications, has a certain degree of versatility, and can adapt to common toothbrush cup shapes and sizes on the market. Whether it is a larger toothbrush cup for adults or a small toothbrush cup for children, a suitable place can be found on this toothpaste holder.

[0109] In terms of hygiene, the combined storage of toothpaste and toothbrush cups reduces the number of items on the washbasin, making cleaning easier and more convenient. Users can clean the toothpaste holder and its cup in one go, avoiding cleaning dead spots caused by scattered items and effectively maintaining a clean and hygienic washing environment. At the same time, the well-designed structure facilitates drainage, preventing water accumulation and bacterial growth inside the toothbrush cup and toothpaste holder, thus ensuring the user's health.

[0110] Reference Figures 1 to 4 In some examples, the second end of the first clamping arm 110 protrudes upward on the side away from the clamping groove 131 to form a toothed cup bearing structure. The connection between the clamping part 130 and the assembly part 140 and the toothed cup bearing structure can respectively bear the two opposite cup walls of the toothed cup.

[0111] The aforementioned structure further optimizes the toothpaste holder's function in storing toothpaste cups, providing more stable and comprehensive support. The toothpaste cup support structure protrudes upwards, engaging with the connection between the clamping part 130 and the assembly part 140 to support the cup wall from two different directions. This dual-support structure greatly enhances the stability of the toothpaste holder when placed on the toothpaste holder, ensuring stability and preventing tipping even when the cup contains a certain amount of water.

[0112] In practical use, when placing the toothbrush cup on the toothpaste holder, the user simply aligns the two sides of the cup with the support structure and the connection between the clamping part 130 and the assembly part 140, and gently lowers it. The operation is simple and convenient, requiring no complicated steps; even children can easily complete the task. Furthermore, the structure can accommodate toothbrushes of different shapes and sizes; whether round, square, or other irregularly shaped, each toothbrush cup can find a suitable place on this toothpaste holder, demonstrating high versatility.

[0113] In some examples, the first clamping arm 110 also includes a hook portion 115, which is provided with at least one hook groove 116, each hook groove 116 being capable of hooking a toothbrush structure.

[0114] The aforementioned structure, which includes a hanging part 115 and a hanging slot 116 on the first clamping arm 110 to hang the toothbrush, makes full use of the existing structure of the toothpaste storage rack from a space utilization perspective. It provides a dedicated place for the toothbrush without taking up too much extra space. Previously, toothbrushes were often placed haphazardly on the washbasin, which not only looked messy but also easily collided with other items. This toothpaste storage rack, with its hanging slot 116 design, neatly stores the toothbrushes, making the washbasin surface more organized and greatly improving space utilization efficiency.

[0115] In terms of hygiene, hanging the toothbrush on the toothpaste holder keeps it a certain distance from the countertop, preventing the bristles from directly contacting any stains or bacteria that may be present on the surface, thus reducing the possibility of contamination. Furthermore, hanging the toothbrush allows it to dry properly, preventing bacterial growth in a damp environment and protecting the user's oral health. After each use, simply hang it in the hanging slot 116 to air dry naturally, making it convenient and hygienic.

[0116] In terms of ease of use, the design of the mounting slot 116 makes it incredibly easy to put on and take off the toothbrush. Users can quickly hang or remove the toothbrush without complicated steps, saving valuable time, especially during a rushed morning routine. Furthermore, the size and shape of the mounting slot 116 can be designed to accommodate different types of toothbrushes, ensuring a suitable mounting position for both manual and electric toothbrushes, making it highly versatile.

[0117] Reference Figure 5 and Figure 6 Optionally, a reinforcing structure 400 is provided on the inner side of the first clamping arm 110 and the second clamping arm 120; and / or, a flanged structure is provided at the edge of the first clamping arm 110 and the second clamping arm 120; and / or, a reinforcing rib 500 is provided between the second clamping arm 120 and the assembly part 140. The reinforcing structure 400 and the flanged structure can strengthen the clamping part 130, and the reinforcing rib 500 can strengthen the toothed cup bearing structure.

[0118] The reinforcing structure 400 significantly enhances the strength and rigidity of the first clamping arm 110 and the second clamping arm 120. When clamping items such as toothpaste and toothbrush cups, the clamping arms need to withstand certain external forces. The reinforcing structure 400 effectively prevents the clamping arms from deforming or being damaged due to stress, ensuring their long-term stable clamping function. For example, the reinforcing structure 400 can be achieved by increasing the wall thickness or adding reinforcing ribs. These methods increase the load-bearing capacity of the clamping arms, allowing them to remain stable when handling items of different sizes and weights.

[0119] The flanged structure, located at the edges of the first clamping arm 110 and the second clamping arm 120, serves multiple functions. Firstly, the flanged structure increases the strength of the clamping arm edges, preventing wear and deformation caused by collisions or friction, thus extending the service life of the clamping arms. Secondly, the flanged structure also provides some protection, preventing users from being accidentally scratched by the edges of the clamping arms during operation, thereby improving product safety.

[0120] A reinforcing rib 500 is provided between the second clamping arm 120 and the assembly part 140, primarily to enhance the stability of the toothbrush holder structure. The toothbrush holder structure needs to bear the weight of the toothbrush, and certain stresses are generated when placing the toothbrush. The reinforcing rib 500 can effectively disperse these stresses, preventing the toothbrush holder structure from breaking or deforming due to stress concentration. The shape and number of the reinforcing ribs 500 can be designed according to actual needs. A reasonable layout of the reinforcing ribs 500 ensures that the toothbrush holder structure has good strength and stability in all directions, ensuring that the toothbrush can be placed safely and securely on the toothpaste holder.

[0121] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
