Description

Technical Field

[0001] This utility model relates to the field of stationery and document parts, and in particular to a multi-purpose pen. Background Technology

[0002] Currently, most pens on the market are equipped with a fixed pen clip, whose main function is to hold the pen to books, pockets, or notebooks to prevent it from rolling or getting lost. These traditional pen clips are simple in structure and single-function, providing only basic securing and failing to meet users' diverse needs for multifunctional, personalized, and portable pens. With the diversification of stationery functions, users expect pens to not only perform writing but also have practical functions such as personalization or temporary item holding. For example, during writing, office work, or study, users often need to temporarily secure papers, documents, hair, or other thin items. The limitations of traditional pen clips restrict their further functional expansion.

[0003] Therefore, it is necessary to develop a new type of pen clip that not only possesses the traditional fixing function but also meets the user's needs in different scenarios. For example, the pen clip can be used independently as a hair clip or folder, thereby enhancing the pen's practicality, convenience, and fun. This utility model aims to solve the technical problem of the traditional pen clip's single function by giving the pen clip multiple usage states through structural innovation. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-purpose pen tool. By designing the pen clip to be detachably connected to the pen body, the pen clip can be used as a traditional pen clip when installed on the pen body, and can be converted into an independent clamping device for separate use after being detached. This effectively expands the function of the pen tool and solves the problem that traditional pen clips have limited functions and cannot balance practicality and recognizability.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A multi-purpose pen includes a pen barrel and a detachable clamp; the detachable clamp and the pen barrel are connected by a connection structure to achieve repeatable, non-destructive, and quick assembly and disassembly; the detachable clamp has: a first working state: when installed on the pen barrel, the detachable clamp can be used to fix the multi-purpose pen; a second working state: when removed from the pen barrel, the detachable clamp can be used as an independent clamping device.

[0007] Furthermore, the connection structure includes a mounting base, and the detachable clamp is detachably connected to the pen barrel via the mounting base.

[0008] Furthermore, the detachable clamp and the mounting base are detachably connected via a mechanical connection structure and / or a magnetic connection structure.

[0009] Furthermore, the detachable clamp is detached and removable by performing linear and / or rotational movements relative to the mounting base.

[0010] Furthermore, the mechanical connection structure is selected from any one or more combinations of snap-fit ​​connection structures, threaded connection structures, or interference-fit embedded connection structures.

[0011] Furthermore, the detachable clamp includes: a first clamping arm, a second clamping arm, and a resilient reset element.

[0012] Furthermore, an elastic reset element is disposed at the first end of the first clamping arm and the second clamping arm and provides a closing force, so that the second ends of the first clamping arm and the second clamping arm remain in contact in a free state; while under the action of external force, they can elastically open.

[0013] Furthermore, the mounting base is equipped with resilient claws.

[0014] Furthermore, the detachable clamp is provided with a locking groove at the corresponding position.

[0015] Furthermore, the elastic claws and the engaging grooves cooperate to form a snap-fit ​​connection structure.

[0016] Furthermore, by applying a pushing or pulling force, the elastic claw can undergo elastic deformation, thereby enabling the detachable clamp to engage and disengage from the mounting base.

[0017] Furthermore, the multi-purpose pen also includes a push-button mechanism located at the far end of the pen barrel for controlling the extension and retraction of the pen tip.

[0018] Furthermore, the outer end face of the detachable clamp is provided with an identification part.

[0019] Furthermore, the identification unit distinguishes itself from the gripper body by its surface contour and / or material, providing visual and / or tactile identification.

[0020] This utility model provides a multi-purpose pen, which has the following advantages over the prior art:

[0021] This invention innovatively transforms the traditional fixed pen clip into a detachable holder that can be independently disassembled. It connects to the pen barrel via a specific connection structure, breaking the limitations of traditional pen functions and giving the pen expanded versatility through modular design. Specifically, this detachable holder has two working states: when installed on the pen barrel, it functions as a pen clip to secure the pen; after being removed from the pen barrel, it transforms into a completely independent clamping device (such as a notepad or temporary document holder), which can be used alone in various scenarios such as office work and study. This design greatly enhances the product's practicality and efficiency, reducing the inconvenience of users having to carry multiple single-function tools simultaneously. Secondly, the detachable connection structure provides operational convenience and connection reliability. Users can quickly install and detach the gripper without additional tools, using only simple linear push-pull or rotation actions, achieving repeatable "non-destructive" assembly and disassembly. This process does not cause wear or damage to the components themselves, ensuring the stability and durability of the connection function throughout the product's lifespan. For example, the engaging structure of the elastic claws and locking grooves provides a clear locking feel (improving operational confirmation) while ensuring mechanical strength in the connected state, effectively preventing accidental detachment during use. Furthermore, by incorporating identification features (such as unique contours or anti-slip textures) on the detachable gripper, not only is tactile recognition improved during assembly and disassembly, preventing slippage, but the independent component also possesses high functional recognizability after being detached from the pen. Users can intuitively and quickly identify its use as an independent tool, improving the efficiency and accuracy of interaction. In summary, through ingenious structural design, this utility model significantly expands the additional functions, ease of operation, and structural reliability of the pen while ensuring the core writing function.

[0062] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0063] See Figures 1-2 The structure of the multi-purpose pen is shown, which includes a push button 1, a mounting base 2, a detachable clamp 3, and a pen barrel 4.

[0064] See Figure 3 The actuator 1 includes a pressing head 11 for the user to press and a guide rod 12 extending downward from the head. The cross-section of the guide rod 12 can be circular, square, or other polygonal, and its lower end is used to contact the tail end of the pen refill (not shown). When the actuator 1 is pressed, it overcomes the force of the internal spring (not shown) of the pen barrel, driving the pen refill (not shown) to extend out of the pen barrel; when pressed again, the pen retracts and is locked under the action of the internal spring. Thus, the extension and retraction of the pen refill is controlled by the actuator 1. This is a conventional press-type pen mechanism, which will not be described in detail here.

[0065] See Figure 4The diagram shows the structure of the mounting base 2. The mounting base 2 is a hollow columnar body, which is fixedly or detachably mounted on the end of the pen barrel 4 away from the pen tip. The hollow channel of the mounting base 2 allows the guide rod 12 of the actuator 1 to pass through, and the actuator 1 can move back and forth relative to the mounting base 2 along the axis to perform the pressing function.

[0066] In this embodiment, the mounting base 2 and the detachable clamp 3 are connected and disassembled via a mechanical structure, specifically a snap-fit ​​connection structure. This structure includes an elastic claw 21. The fixed end of the elastic claw 21 is connected to the body of the mounting base 2, while the other end is a free end. The elastic claw 21 has a certain thickness and elastic deformation capability; specifically, it can be made of materials with good toughness and wear resistance, such as polyoxymethylene (POM) or nylon (PA). At least one engaging protrusion 22 is formed on the inner side of the elastic claw 21.

[0067] Optionally, the lower outer wall of the mounting base 2 may also be provided with an external thread (or snap-fit ​​structure) for engaging with the internal thread (or corresponding groove) of the pen barrel 4 to achieve a fixed connection between the mounting base 2 and the pen barrel 4. Alternatively, the mounting base 2 can also be integrated with the pen barrel 4 by ultrasonic welding, bonding, or integral injection molding. The selectivity of the connection method between the mounting base 2 and the pen barrel 4 allows this solution to flexibly adapt to diverse production needs and market positioning. The most suitable connection process can be selected based on the cost control requirements of the target market, product positioning, and expected service life.

[0068] See Figure 5 The detachable clamp 3 includes a first clamping arm 31, a second clamping arm 32, and an elastic reset element 33 disposed at their first ends (connecting ends). The first clamping arm 31 and the second clamping arm 32 are connected at the connecting ends by a pivot or rivet, allowing them to open and close relative to each other using that point as a fulcrum. Preferably, see [reference needed]. Figures 9-13 The elastic reset element 33 is a spring located at the first end. When the first clamping arm 31 and the second clamping arm 32 open under external force, the spring is compressed, storing elastic potential energy. When the external force is removed, the spring releases the potential energy, driving the clamping arms to reset. Even when the clamp is in a naturally closed state (i.e., without external force), the spring remains slightly pre-compressed, thus continuously providing a stable initial closing force to the clamping ends of the first clamping arm 31 and the second clamping arm 32. This ensures that they reliably remain in contact or nearly in contact in their free state, preventing accidental release of the clamped items. This design guarantees the effectiveness and reliability of the clamping action.

[0069] Optionally, the elastic reset element 33 is a torsion spring sleeved on the rotating shaft. Its two ends of the torsion arms act on the first clamping arm 31 and the second clamping arm 32 respectively, continuously providing a closing force that brings the second ends (clamping ends) of the two arms closer together. Therefore, in the free state, the clamping ends of the first clamping arm 31 and the second clamping arm 32 always remain in a state of contact or near contact; while when an external force is applied to the two clamping arms, they can overcome the elastic force and elastically open.

[0070] For cooperation with the elastic claw 21 on the mounting base 2, see Figures 9-14 The detachable gripper 3 has a connecting portion at its connection point (typically on the back of the first gripping arm 31). This connecting portion has a locking groove 34 that matches the resilient claw 21. The shape and size of the locking groove 34 are designed to accommodate at least a portion of the free end of the resilient claw 21, and the locking groove 34 includes complementary structures adapted to the shape of the locking protrusion 22 to ensure connection stability. Furthermore, a guide structure may be designed around the connecting portion to assist in alignment during installation.

[0071] The outer end face of the detachable gripper 3 (e.g., the outer side of the second gripping arm 31) is provided with an identification part 35. This identification part 35 can be achieved through its unique surface contour (such as anti-slip texture, raised pattern) and / or by using a different material from the gripper body (such as embedded rubber, soft rubber). This provides high visual and / or tactile recognition: visually, the user can quickly identify the independent component as a functional gripper after the pen is detached; tactilely, it increases friction during disassembly / reassembly or when used alone, preventing slippage and improving operational accuracy and safety.

[0072] Optionally, the recognition part 35 can be specifically designed as a highly recognizable contour, such as, but not limited to, a flower shape or a wave shape. Taking a flower shape as an example, it can enhance functional identification and operational intuition: As a highly symbolic form, the flower shape can intuitively convey to the user the functional attributes of the component independent of the pen. When the holder is removed from the pen body, the user can quickly identify it as an independent, handheld functional tool (rather than a fragment of the pen) through this unique contour, improving the intuition of function switching and operational efficiency. Furthermore, it can optimize tactile feedback and anti-slip performance: The irregular contour and unevenness inherent in the flower shape significantly increase the friction between the user's fingers and the contact surface of the holder. This not only effectively prevents slippage when assembling and disassembling the holder, ensuring the accuracy and safety of operation, but also provides a stable grip when using the holder alone, enhancing the reliability of use. The complex contour edges can provide clear tactile positioning points for the fingertips, enabling directional identification under blind operation. Furthermore, it can enhance product appeal and user engagement: unique designs (such as flowers) can generate positive and engaging feedback. This fun and interactive experience can motivate users to use the multifunctional component, thus maximizing its design utility in practice and preventing it from becoming idle due to concealed functions.

[0073] See Figure 6 The pen barrel 4 is a hollow tubular structure used to house the pen refill and related springs of the pressing mechanism. Its top has an internal thread (or bayonet) for connecting to the mounting base 2. The pen barrel 4 can be made of plastic, metal, or composite materials, and its shape can be ergonomically designed to provide a comfortable grip.

[0074] See Figure 7 , Figure 8 This is a schematic diagram illustrating the switching between the first and second working states of a multi-purpose pen. (Example:) Figure 7 As shown, the detachable clip 3 is stably mounted on the mounting base 2 via a snap-fit ​​connection structure. In this case, its function is the same as a traditional pen clip, which can be used to hold the entire pen in a book, pocket, or notebook.

[0075] State Switching (Disassembly Process): When the detachable gripper 3 needs to be used as an independent clamping device, the user holds the detachable gripper 3 and applies sufficient pulling force in the opposite direction to the installation direction. This pulling force causes the elastic claw 21 to elastically deform, and its engaging protrusion 22 disengages from the engaging groove 34, thereby separating the detachable gripper 3 from the mounting base 2. This process is "non-destructive," meaning that the connection structure will not be damaged by repeated disassembly and assembly.

[0076] See Figure 9 , Figure 10 At this point, the detachable clamp is used as a completely independent clamping device. Figure 9 The closed state is shown, at which point the clamping end is in contact with the elastic reset element 33. Figure 10 The image shows its open state. When the user squeezes the gripping ends of the first gripping arm 31 and the second gripping arm 32, the clamp opens and can grip items such as hair, paper, and fabric. The recognition unit 35 provides good tactile feedback and recognition in this state.

[0077] Reinstallation: Simply align the connecting part of the detachable clamp 3 with the mounting base 2 again and push it axially to repeat the above engagement process and restore it to the first working state. This "repeatable, non-destructive quick-release" feature greatly enhances the product's practicality and service life.

[0078] Although Embodiment 1 describes in detail the snap-fit ​​connection method via linear movement, the scope of protection of this utility model is far from limited to this. The following are several alternative solutions, all of which achieve the same technical effect: detachable pen clips and functional conversion.

[0079] Alternative connection methods:

[0080] Magnetic connection structure: A permanent magnet can be embedded in the mounting base 2, while another permanent magnet or magnetically conductive material (such as an iron sheet) is embedded in the connecting part of the detachable clamp 3. Connection is achieved through magnetic attraction. Disassembly is achieved by applying a pulling or torsional force exceeding the magnetic force. This method is quiet, smooth, and free from mechanical wear.

[0081] Threaded connection structure: External threads are provided on the outside of the mounting base 2, and corresponding internal threads are provided on the inside of the connecting part of the detachable clamp 3. Connection and separation are achieved through rotational movement. This method provides a strong and stable connection with low processing costs.

[0082] Interference-fit embedded connection: The connecting part of the detachable clamp 3 is designed as a columnar body slightly larger than the corresponding insertion hole on the mounting base 2, and a slight interference fit generates friction to achieve fixation. It can be pulled out directly for disassembly.

[0083] Alternatives to the disassembly and assembly method:

[0084] In addition to linear motion, assembly and disassembly can also be achieved through rotational motion (as in the threaded connection described above). For example, using a "bayonet" connection (similar to a camera lens), after aligning the detachable clamp 3 with the mounting base 2, rotating it a certain angle (such as 90 degrees) will lock or release it through the internal cam groove structure.

[0085] It is easy to understand that, whether it is linear motion or rotational motion in this alternative, the assembly and disassembly method is determined by the physical form of the specific connection structure selected.

[0086] Functionality expansion:

[0087] The detachable clamp 3 is an independent component, and its form is not limited to hair clips or folders. It can be designed in different sizes, clamping forces, or end shapes (such as flat or round openings) to meet the needs of clamping different items (such as mobile phones, earphone cords, and banknotes), forming a series of functional modular accessories.

[0088] Industrial application

[0089] In summary, this utility model provides a multi-purpose pen holder. By innovatively designing the traditional fixed pen clip into a detachable holder that can be independently disassembled, and combining it with the pen barrel through a specific connection structure, this invention breaks through the limitations of traditional pens with only one function. The modular design endows the pen holder with expanded multi-functionality. Specifically, this detachable holder has two working states: when installed on the pen barrel, it functions as a pen clip to secure the pen; after being removed from the pen barrel, it transforms into a completely independent clamping device (such as a hair clip, notepad, or temporary document holder), which can be used independently in various scenarios such as office work and study. This design greatly enhances the product's practicality and efficiency, reducing the inconvenience of users having to carry multiple single-function tools simultaneously. Secondly, the detachable connection structure provides operational convenience and connection reliability. Users can quickly install and detach the gripper without additional tools, using only simple linear push-pull or rotation actions, achieving repeatable "non-destructive" assembly and disassembly. This process does not cause wear or damage to the components themselves, ensuring the stability and durability of the connection function throughout the product's lifespan. For example, the engaging structure of the elastic claws and locking grooves provides a clear locking feel (improving operational confirmation) while ensuring mechanical strength in the connected state, effectively preventing accidental detachment during use. Furthermore, by incorporating identification features (such as unique contours or anti-slip textures) on the detachable gripper, not only is tactile recognition improved during assembly and disassembly, preventing slippage, but the independent component also possesses high functional recognizability after being detached from the pen. Users can intuitively and quickly identify its use as an independent tool, improving the efficiency and accuracy of interaction. In summary, through ingenious structural design, this utility model significantly expands the additional functions, ease of operation, and structural reliability of the pen while ensuring the core writing function.
