[0039] Please see Figures 1 to 4 This utility model provides a nail grinder assembly 100, including a control module 10 and a nail grinder 20. The control module 10 is electrically connected to the nail grinder 20. The control module 10 includes a housing assembly 1 and a telescopic cable module 2 disposed within the housing assembly 1. The movable end 212 of the telescopic cable module 2 passes through the housing assembly 1 and is connected to the input end of the nail grinder 20, thus achieving an electrical connection. The housing assembly 1 includes a detachably connected lower housing 12 and an upper housing 11. One end of the upper housing 11 is provided with a communicating opening 111 and... The movable end 212 of the telescopic cable module 2 can be stored in the receiving groove 112 after passing through the opening 111. The receiving groove 112 is located on the outer surface of the upper housing 11. The insertion structure 110 is set inside the receiving groove 112. The upper housing 11 is also provided with a mounting hole 113 that connects the receiving groove 112 and the interior of the upper housing 11. The lower housing 12 is provided with a support baffle 121. When the upper housing 11 and the lower housing 12 are assembled, the support baffle 121 is exposed through the mounting hole 113 and closes the mounting hole 113.

[0040] Understandably, this integrated design cleverly incorporates the telescopic cable module 2 and plans the storage space for its movable end 212. At the same time, by setting up detachable upper and lower housings 12, and integrating a storage channel composed of a through-hole structure 110, an opening 111, a receiving groove 112, and a mounting hole 113 in the upper housing 11, and utilizing the support baffle 121 of the lower housing 12 to close and support through the mounting hole 113, the smooth extension and retraction, directional storage, and effective protection of the movable end 212 are achieved, as well as reliable isolation between the inner and outer spaces of the housing, thus achieving a unity of functionality and manufacturability.

[0041] Specifically, the control module 10 serves as the core, and its housing consists of an upper housing 11 and a lower housing 12 connected by screws and clips for easy assembly and maintenance. The telescopic cable module 2 is built into the housing, with its movable end 212 protruding from the opening 111 in the upper housing 11. After use, it can be coiled and embedded in the receiving groove 112. The receiving groove 112 is a recess on the surface of the upper housing 11. The mounting hole 113 and the insertion structure 110 are located at both ends of the receiving groove 112. After the upper and lower housings 12 are assembled, the mounting hole 113 at the bottom is filled and sealed by the support baffle 121 integrally extended from the lower housing 12. The support baffle 121 provides bottom support for the receiving groove 112 and prevents dust from entering the housing through the mounting hole 113. The insertion structure 110 solves the problem of undercut during mold demolding and can also fix the movable end 212 of the telescopic cable module 2.

[0042] Please refer to further information. Figure 3 and Figure 5 The mounting hole 113 and the opening 111 are connected by the receiving groove 112.

[0043] Understandably, the mounting hole 113 and the opening 111 form a continuous channel through the receiving groove 112. On the one hand, this provides a clear and straight guiding channel for the cable from the installation area of ​​the telescopic cable module 2 to the external cable outlet of the product, so that the cable does not need to detour or be forcibly squeezed through the broken structural gaps. On the other hand, the cable can be directly aligned with the channel during assembly, and can also be smoothly threaded through the channel in one go during wiring. This avoids cable jamming and breakage, and greatly reduces the difficulty of operation. Therefore, this layout greatly facilitates the assembly and wiring process of the telescopic cable module 2.

[0044] Specifically, the opening 111 is for the cable to pass through, the mounting hole 113 is for the movable end 212 to pass through, and the receiving groove 112 is the storage space for the movable end 212. The three are physically connected, making the entire storage process smoother, and when needed, users or assemblers can observe or clean the interior through this continuous channel.

[0045] The upper housing 11 has a cable routing channel inside, which is a path for accommodating and guiding cables. Its end is "precisely connected" to the opening 111 in spatial position. The cable routing channel provides "path guidance" for the cable and the movable end 212 to extend from the inside of the housing to the opening 111, so that the cable can smoothly reach the "exit node" of the opening 111.

[0046] Please refer to further information. Figure 4 and Figure 5 The telescopic line module 2 is provided with a limiting block 22. When the movable end 212 is retracted into the receiving groove 112, the limiting block 22 abuts against the support baffle 121 and the upper shell 11.

[0047] Understandably, the design of the limit block 22 provides a precise mechanical stop point for the retraction process of the movable end 212, preventing over-retraction and ensuring that the movable end 212 can accurately stop in the ideal position in the receiving slot 112 each time, making it convenient for the user to retrieve it next time. At the same time, it disperses stress through the supporting action, protects the cable and internal components, and extends the service life.

[0048] Specifically, the retractable cable module 2 includes a cable reel 21 and a limiting block 22. The limiting block 22 acts as a mechanical stop and has a cable outlet hole in the middle. Its installation position is precisely calculated. When the movable end 212 is retracted to the predetermined minimum length through the cable outlet hole, the limiting block 22 contacts the support baffle 121 and the inner wall of the upper housing 11, forming a mechanical stop to prevent the cable reel 21 from over-retracting the cable, causing jamming or damage.

[0049] Furthermore, the limiting block 22 is an elastic element.

[0050] Understandably, the use of elastic limit block 22 can absorb the remaining kinetic energy of the rewinding mechanism while achieving effective limiting, thus playing a buffering role, reducing impact noise and component wear, and can accommodate certain assembly tolerances.

[0051] Specifically, the elastic element can be made of rubber, silicone, or foam material, and its shape can be square or cylindrical, fitted or glued to the cable. When it comes into contact with the support baffle 121 and the inner wall of the upper housing 11, it will undergo slight deformation, thereby gently achieving the limiting function.

[0052] Please refer to further information. Figure 6 The support baffle 121 is integrally formed with the lower shell 12.

[0053] Understandably, the unibody molding process greatly enhances the structural strength and integrity of this part, avoiding loosening, gaps, and additional production costs that may occur when assembling multiple parts. It also improves the sealing and protection performance inside the housing. The lower housing 12 and the support baffle 121 can be formed in one piece using injection molding, making the support baffle 121 an inseparable component of the lower housing 12. This ensures that the support baffle 121 will not separate from the main body under long-term load and stress, resulting in a more robust and durable structure.

[0054] Please refer to further information. Figure 1 , Figure 2 and Figure 5 The movable end 212 of the telescopic line module 2 is detachably connected to the input end of the armor grinder 20.

[0055] Understandably, the detachable connection design gives the device great flexibility in use, allowing users to quickly change different types of nail grinders 20 as needed, or to separate the nail grinders 20 from the main unit for separate cleaning and storage.

[0056] Furthermore, the movable end 212 of the telescopic line module 2 and the input end of the armor grinder 20 are detachably connected via a plug-in connection, a magnetic connection, or a snap-fit ​​connection.

[0057] Understandably, it provides a variety of reliable physical connection solutions to meet the connection needs of different users and usage scenarios, ensuring both the stability of electrical connections and the convenience and robustness of the connection.

[0058] Specifically, plug-in connections can achieve quick plugging and data synchronization via USB-C, Micro-USB, or round connectors; magnetic connections utilize magnetic attraction to achieve automatic alignment and connection, which is easy to operate and durable; and snap-on connections use a mechanical snap-on structure to achieve a secure connection and one-click disassembly. Users can choose different connection methods according to their usage scenario preferences.

[0059] Please refer to further information. Figure 4 , Figure 5 and Figure 7 The control module 10 includes a control component 13, a telescopic wire module 2 and an armor grinder 20 located on one side of the housing assembly 1, while the control component 13 is located on the other side of the housing assembly 1.

[0060] Understandably, this functional zoning layout enables modular design, effectively reduces cross-interference of internal circuits, optimizes heat dissipation paths, and makes the equipment structure more compact, the logic clearer, and easier to produce and maintain.

[0061] Specifically, the interior of the casing is physically or logically divided into two main areas: one side is where the telescopic cable module 2 and its outlet are centrally located, and the armor grinder 20 is also connected to this side; the other side is where the control components 13 are centrally installed, including the power button 131, display screen 132, forward / reverse switch 133, circuit board 134, speed control knob 135, charging port 136 and battery 137, forming a clear functional partition.

[0062] Please refer to further information. Figure 1 and Figure 2 The circumferential side of the housing assembly 1 is provided with an annular fixing member 14 for placing the armor grinder 20, and the annular fixing member 14 is located on the same side as the armor grinder 20.

[0063] Understandably, placing the annular fixing part 14 on the same side as the armor grinder 20 conforms to the principles of ergonomics, realizes the convenient operation flow of "use and take, put and store", shortens the picking and putting path of the armor grinder 20, improves the efficiency of use, and maintains the overall appearance of the equipment.

[0064] Specifically, the annular fastener 14 has a tapered cylindrical structure, with two protruding block-like structures extending from the outer side of the cylinder. These are secured to the same side of the shell as the nail grinder 20 via snap-fit. Simultaneously, the inner wall of the cylinder has a contour that matches the part of the nail grinder 20 to be secured, ensuring a close fit during contact. Furthermore, the annular fastener 14 achieves stable fixation of the nail grinder 20 through friction. That is, the tapered shape and contour of the inner wall of the annular fastener 14 perfectly match the shape of the corresponding part of the nail grinder 20, forming a tight surface contact. This effectively prevents relative sliding using friction, therefore, the nail grinder 20 must have a surface that matches the annular fastener 14. After use, the user can easily insert the nail grinder 20 into the fastener, preventing it from being lost due to careless placement.

[0065] Please continue reading. Figure 1 and Figure 2 The back of the housing assembly 1 is provided with a rotating bracket 15. When the rotating bracket 15 is unfolded and supports the housing assembly 1, the placement entrance of the annular fixing member 14 faces upward.

[0066] Understandably, this orientation design ensures that the nail grinder 20 is easy to access and store when placed, preventing accidental slippage, while optimizing human-computer interaction and maintaining a stable and intuitive operating posture when the product is supported.

[0067] Specifically, the rotating bracket 15 has a multi-angle adjustment function, which can realize the folded and unfolded states of the housing component 1. In the folded state, the housing component 1 can be hung on a clothing pocket to enhance portability, or placed flat on a table; in the unfolded state, the housing component 1 can be tilted at a certain angle to the table, with the opening of the annular fixing member 14 facing upward, so that the screen and buttons are in the best viewing and operating position, which is ergonomic and makes it easy for users to view the screen and operate the buttons.

On this basis, by setting up detachable upper and lower housings 12, and integrating a storage channel composed of an opening 111, a receiving groove 112 and a mounting hole 113 in the upper housing 11, and using the support baffle 121 of the lower housing 12 to close and support through the mounting hole 113, the smooth extension and retraction of the movable end 212, directional storage and effective protection, and reliable isolation of the inner and outer spaces of the housing are achieved. Among them, the control module 10 serves as the control and power supply center of the component, providing power and commands to the armor grinder 20; the telescopic cable module 2 is responsible for connecting and flexibly adjusting the cable length, fundamentally solving the problem of cable storage and management; the opening 111 provides a smooth and protected path for cable extension and retraction, avoiding wear between the cable and the edge of the housing; the receiving slot 112 provides a dedicated hidden storage space for the movable end 212, ensuring the clean appearance of the equipment; the mounting hole 113 allows the support baffle 121 to be exposed and the hole to be closed, providing bottom support for the receiving slot 112 to enhance structural strength, and also serving as a barrier to effectively prevent dust and foreign objects from entering the housing through the mounting hole 113.
