[0049] Please refer to further information. Figure 1 , Figure 2 and Figure 5 The telescopic cable module 2 is equipped with a cable reel 21, which includes a housing 211 and a coil spring 2111, a cable reel 2112, a limiting groove 2113, and a locking mechanism 2114 disposed inside the housing 211. The coil spring 2111 is located in the cable reel 2112. A central shaft 2115 is provided at the center of the housing 211. A through hole 21121 is provided at the center of the cable reel 2112 and rotates with the central shaft 2115. One end of the coil spring 2111 is fixedly connected to the central shaft 2115, and the other end of the coil spring 2111 is fixedly connected to the movable end 212 of the telescopic cable module 2. When the movable end 212 of the telescopic cable module 2 on the cable reel 2112 is stretched outward, the coil spring 2111 is in a coiled state when rotating forward or backward. The locking mechanism 2114 is slidably connected in the limiting groove 2113. The cable reel 2112 is rotatably connected to the housing 211. When the coil spring 2111 resets, it drives the cable reel 2112 to rotate and reel in the cable.

[0050] Specifically, the reel 21 utilizes the energy storage and release of the coil spring 2111 to achieve automatic cable winding and unwinding. When the movable end 212 of the telescopic cable module 2 is pulled out, the coil 2112 rotates, causing the coil spring 2111 to accumulate elastic potential energy; after being released, the coil spring 2111 restores its deformation, causing the coil 2112 to reverse, neatly retracting the movable end 212 of the telescopic cable module 2 into the housing 211. The locking mechanism 2114 cooperates with the limiting groove 2113 to lock the coil 2112 at a specific position after being pulled out, preventing accidental retraction.

[0051] Furthermore, the housing 211 is provided with a protrusion 2116, and the locking mechanism 2114 is provided with a rotating hole 21141. The protrusion 2116 cooperates with the rotating hole 21141 to slide in both forward and reverse directions.

[0052] Understandably, the protrusion 2116 on the housing 211 cooperates with the rotating hole 21141 on the locking mechanism 2114, allowing the locking mechanism 2114 to slide forward and backward relative to the housing 2111, thereby realizing the functional adjustment or position locking of the armor grinder 20. This structure simplifies the assembly of components and improves the convenience and reliability of operation.

[0053] Please refer to further information. Figure 1 , Figure 2 , Figure 3 and Figure 6 The housing assembly 1 includes an upper housing 11, which has a communicating opening 111 and a receiving groove 112. The movable end 212 of the telescopic cable module 2 passes through the opening 111 and is housed in the receiving groove 112, which is located on the outer surface of the upper housing 11.

[0054] Specifically, the opening 111 in the upper housing 11 provides a channel for the telescopic movement of the movable end 212 of the telescopic cable module 2. The receiving groove 112 is located on the outer surface of the upper housing 11, communicating with the opening 111 and the mounting hole 113. The receiving groove 112 and the power button 131 are located on the same side of the housing assembly 1 and spaced apart, and their shape matches the movable end 212 of the telescopic cable module 2. When the clipper 20 is not in use, the user can remove the movable end 212 of the telescopic cable from the clipper 20 and properly place it in the receiving groove 112. This design provides a fixed storage location for the connector head, avoiding cable tangling and a messy appearance caused by random hanging or placement. At the same time, the receiving groove 112 shields and protects the connector head, effectively preventing dust, moisture, and other contaminants from entering the interface, or damage to the interface due to accidental collisions or scratches, thus extending the service life of the components. The support baffle 121 inside the lower housing 12 provides internal support for the telescopic cable module 2, ensuring its stability during operation.

[0055] Please combine further Figure 1 , Figure 2, Figure 4 and Figure 6 The housing assembly 1 includes a lower housing 12, which is detachably connected to an upper housing 11. The lower housing 12 is provided with a support baffle 121, and the telescopic line module 2 is provided with a limiting block 22. When the movable end 212 of the telescopic line module 2 is retracted into the receiving groove 112, the limiting block 22 abuts against the support baffle 121 and the upper housing 11.

[0056] Specifically, the limiting block 22 acts as a mechanical stop, with a cable outlet hole in the middle, and its installation position is precisely calculated. When the movable end 212 of the telescopic cable module 2 is retracted to the predetermined minimum length through the cable outlet hole, the limiting block 22 just contacts the support baffle 121 and the inner wall of the upper housing 11, preventing the cable reel 2112 from rotating further and preventing the cable from being excessively retracted and wound into the mechanism, causing the cable to jam or be damaged.

[0057] Please combine further Figure 1 , Figure 3 and Figure 4 The housing assembly 1 has an annular fastener 14 on its circumferential side, and the annular fastener 14 is detachably connected to the housing assembly 1.

[0058] Specifically, there are no other button structures on the side where the annular fixing member 14 is located, and it is located on the opposite side of the forward / reverse switch 133 and the speed control knob 135.

[0059] Understandably, the main function of the annular fastener 14 is to serve as a dedicated bracket or holder for the nail grinder 20. When the nail grinder 20 is separated from the control module 10, the user can directly snap or fix the nail grinder 20 onto the annular fastener 14, thus providing a clear and secure location for the nail grinder 20. This design effectively solves the problem of the nail grinder 20 being easily lost or damaged by falling from a height. The annular fastener 14 is detachably connected to the housing assembly 1, allowing users to choose to install or remove it according to their personal usage habits. It can also be removed when not in use to keep the housing 211 uncluttered. By integrating the storage function of the nail grinder 20 into the control module 10, the overall integration and storage convenience of the component are improved, eliminating the hassle of searching for the nail grinder 20.

[0060] Furthermore, a rotating bracket 15 is provided on the back of the housing assembly 1. When the rotating bracket 15 is unfolded and supports the housing assembly 1, the placement entrance of the annular fixing member 14 faces upward.

[0061] Understandably, the rotating bracket 15 allows for multi-angle adjustment of the housing assembly 1, making it convenient for users to view the screen and operate the buttons.

[0062] Specifically, the rotating bracket 15 has rotating clamps on both sides and a limiting abutment in the middle. The housing assembly 1 has two positioning mating parts that cooperate with the rotating clamps. Each positioning mating part includes a rotating shaft and a limiting mating part. The rotating clamps are rotatably connected via the rotating shaft. During rotation, when the rotating bracket 15 rotates 90° to a specific designed position, the limiting abutment on the rotating bracket 15 abuts against the limiting mating part on the lower housing 12. This abutment limits further rotation of the rotating bracket 15, stabilizing it in the working position. When the rotating bracket 15 is unfolded and the device stands on the table, the design ensures that the interface of the annular fixing member 14 faces upwards, allowing the user to smoothly pick up and put down the nail polisher 20 or perform other accessory connection operations in this posture, conforming to ergonomics.

After passing through the housing assembly 1, it connects to the input end of the armor grinder 20 and achieves electrical connection; the telescopic cable module 2 is provided with a cable reel 21, which includes a housing 211 and a coil spring 2111, a cable reel 2112, a limiting groove 2113, and a locking mechanism 2114 disposed inside the housing 211. The coil spring 2111 is located in the cable reel 2112. A central shaft 2115 is provided at the center of the housing 211, and a through hole 21121 is provided at the center of the cable reel 2112 and rotates with the central shaft 2115. One end of the coil spring 2111 is fixedly connected to the central shaft. On 2115, the other end of the coil spring 2111 is fixedly connected to the movable end 212 of the telescopic cable module 2. When the movable end 212 is stretched outward, the coil spring 2111 coils and stores energy. The locking mechanism 2114 is slidably connected in the limiting groove 2113. The cable reel 2112 is rotatably connected to the housing 211. The coil spring 2111 resets and drives the cable reel 2112 to rotate to achieve automatic cable winding. The locking mechanism 2114 includes a protrusion 2116 extending into the movement path. The protrusion 2116 slides in the movement path in coordination with the forward and reverse rotation of the cable reel 2112 to realize the cable reel 2112's automatic winding. The rotation locking and unlocking mechanism of 112; the housing assembly 1 includes a detachably connected upper housing 11 and lower housing 12. The upper housing 11 has a communicating opening 111 and a receiving groove 112, and the lower housing 12 has a support baffle 121. The movable end 212 of the telescopic cable module 2 passes through the opening 111 and can be stored in the receiving groove 112, which is located on the outer surface of the upper housing 11. The telescopic cable 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 housing 11 to prevent excessive retraction. During operation, the user operates the nail polisher 20 through the control component 13. The movable end 212 of the telescopic cable module 2 can be flexibly extended and retracted according to usage requirements to avoid cable tangling and length limitations. After use, the coil spring 2111 automatically retracts the cable, and the limiting block 22 and the support baffle 121 cooperate to limit the cable movement, maintaining neatness and portability. The overall structure is reasonable, the functions are complete, and it is suitable for various usage scenarios.
