[0002] Mouse clamp is a common auxiliary equipment, to help user to fix mouse line in specific position, to reduce the drag and friction of mouse line in use process, to improve the use experience of mouse. The design of traditional mouse clamp is usually relatively simple, its basic function is to prevent mouse line from unnecessary friction or resistance with desktop in operation process by fixing mouse line.

[0003] The mouse clamp on the market at present mainly includes following several types: suction cup fixed type mouse clamp, paste glue fixed type mouse clamp, gravity base fixed type mouse clamp and clamp fixed type mouse clamp. Suction cup fixed type mouse clamp is fixed with desktop by suction cup;Paste glue fixed type mouse clamp utilizes adhesive to fix line clamp on desktop;Gravity base mouse clamp relies on its own weight to fix line clamp;Clamp type mouse clamp is fixed by clamping the edge of desktop or other support. The common feature of these mouse clamps is to determine its position on desktop by certain fixing mode, to avoid excessive drag and friction of mouse line.

[0004] Although existing mouse clamp technology can reduce the friction and drag resistance between mouse line and desktop to some extent, these traditional designs still have the following technical defects:

[0005] 1. Limited use range: although the fixing mode of traditional mouse clamp is suitable for small range of use scene, in larger mouse pad (such as width 400mm or more) or use scene requiring larger activity space, the fixed position of line clamp often cannot adapt to the free movement of mouse. When mouse moves, due to the fixed position of line clamp, user will feel restricted and inconvenient, cannot realize the flexible and free movement of mouse, and it is difficult to meet the user's demand for space in operation.

[0006] 2. Dragging resistance fluctuation: another problem of existing mouse clamp design is that the friction between mouse line and desktop is not constant. In the process of bending or moving mouse line, the fluctuation of friction will cause the instability of drag resistance. This fluctuation will interfere with the accurate control of mouse, especially when detailed operation is needed, it may affect the smoothness of mouse, resulting in the operation experience of user being affected.

[0007] 3. Friction and pressure instability: Mouse clips usually constrain the position of the mouse cord by contacting the desktop, but the stability of friction is disrupted due to changes in friction, especially when the mouse cord passes through a bend. In addition, the pressure of the clip and the desktop contact may also be uneven, causing friction instability, which negatively affects the control accuracy and comfort of the mouse, especially in scenarios with high precision requirements, such as gaming or design work.

[0008] Therefore, although the traditional mouse cord clip can provide convenience to a certain extent, its technical design still cannot fully meet the needs of users in different use scenarios, and there are deficiencies in the accuracy and smoothness of mouse operation. Therefore, it is necessary to develop new mouse cord clip technology to solve the above problems. Invention content

[0038] Embodiment 1

[0039] As shown in the description accompanying drawings Figures 1-2 The utility model discloses a kind of arm clips for mouse line, including arm hoop 1, extension arm 2 and line seat 5.The profile of arm hoop 1 is compatible with the shape of user's forearm, for fixing arm clip on the forearm of user, ensure that device does not slide or shift during operation.In the axial direction side of arm hoop 1 is equipped with extension arm 2, extension arm 2 extends to appropriate length to limit the rotation of arm hoop.The surface of extension arm 2 is equipped with positioning structure, for accurately guiding and fixing mouse line, to prevent mouse line from sliding or winding during use.Line seat 5 is arranged in the top front end area of extension arm 2, to provide the initial guiding positioning of mouse line.Line slot 50 is arranged in the outer side of arm hoop 1, for fixing and guiding the position and extension direction of mouse line.Further, line slot 50 is opened in the upper surface of line seat 5, for accommodating mouse line.The cross-sectional shape of line slot 50 is full-enclosed structure or semi-enclosed structure, when it is full-enclosed structure, mouse line is completely covered inside, only opening is left at inlet and outlet;When it is semi-enclosed structure, for example, U-shaped, C-shaped or other shape with partial opening, it is convenient for mouse line to be put in or taken out.

[0040] In the preferred implementation of the present application, the arm cuff 1 is an arc-shaped structure, the inner surface of which is a concave surface on the inner side of the arm cuff 1, and the opening angle of the arc-shaped structure is 30° to 240° to meet the needs of different body types and dressing conditions. The opening angle conforms to the natural curve of the human forearm, meets the ergonomic requirements, and provides comfort and support when worn. The inner width of the arm cuff 1 ranges from 45 to 80 mm to accommodate the forearm widths of most adults. The inner height of the arm cuff 1 ranges from 25 to 35 mm to provide sufficient coverage without causing compression. Through the design of this size range, the arm cuff can maintain good adaptability among users of different forearm sizes, providing good clamping effect and comfort in both dressed and undressed conditions, while ensuring stability and comfort when worn.

[0041] The material of the arm cuff 1 is selected to be lightweight and durable, such as silicone or other skin-friendly and elastic materials. Silicone not only has good elasticity, which can effectively reduce the compression of the forearm when worn, but also has good wear resistance and aging resistance, suitable for long-term wear. In addition, skin-friendly materials can improve the comfort of wearing and reduce skin irritation, making them more suitable for long-term use and different environmental operation needs.

[0042] In the preferred implementation of the present application, the extension arm 2 extends along the direction of the user's forearm. By extending the extension arm backward along the forearm, the management of the mouse cord is further optimized, reducing the possibility of cable drag. The part of the mouse cord that comes out of the mouse forms a fixed section of mouse cord after passing through the cable slot, and the mouse cord behind this fixed section naturally extends backward and connects to the host computer. This length of positioning structure not only controls the path of the mouse cord, but also avoids the mouse cord from sagging or contacting the mouse pad, fundamentally reducing the interference of the mouse cord with mouse movement.

[0043] The main body of the extension arm 2 is a long strip-shaped structure with a length greater than 70 mm. This length range can support the positioning of the mouse cord in the air and avoid excessive length affecting the hand movement space. The width of the extension arm 2 is 3 to 5 cm, which can ensure the structural stability of the extension arm without being too bulky. To ensure that the extension arm remains stable and does not easily bend and deform during use, the thickness of the extension arm 2 is 3 to 5 mm, which can provide sufficient strength and rigidity while maintaining overall lightness, suitable for long-term wear and operation when using ABS plastic or carbon fiber composite materials.

[0044] The arm clip structure of the present embodiment can provide diversified advantages to meet the needs of users in various environments.

The arm clip of the present embodiment guides and suspends the mouse cord, effectively avoiding the interference of the mouse cord with the desktop, making the mouse move more smoothly and not being limited by the desktop environment, thereby improving office efficiency and comfort. For example, in a game scenario, the game operation requires fast movement and precise control of the mouse, and any dragging resistance will affect the player's operation performance. The wire slot provided on the extension arm 2 of the present embodiment keeps the mouse cord in a suspended state during use, completely eliminating the dragging resistance of the mouse cord, so that the player can have a smoother mouse control experience, improve the reaction speed and operation accuracy in the game, and be suitable for high-intensity game scenarios such as e-sports. For example, in scenarios such as graphic design, 3D modeling, video editing, etc. that require precise operation, stable mouse control is particularly important. The arm clip of the present embodiment fixes the mouse cord, avoiding the slight displacement caused by dragging, so that designers can focus more on detailed operations, improving the accuracy and smoothness of creation.

The end cap 4 is arranged at the front end of the wire seat 5 and the wire guide cover 3, and it clamps the front ends of the wire seat 5 and the wire guide cover 3 together in a plug-in manner.

[0047] In the preferred implementation of the present application, the front end of the wire seat 5 is designed to be inclined upward, preferably at an angle of 10° to 15°, to guide the mouse cord to enter the wire slot 50 smoothly and prevent the cable from being unevenly stressed or bent during the guiding process. The front end of the wire slot 50 is designed as a circular arc segment to facilitate the natural entry of the mouse cord into the wire slot and avoid sharp corners that can wear the cable. After the circular arc segment, the wire slot 50 gradually transitions to a straight segment and extends towards the rear end of the wire seat 5, ensuring that the mouse cord remains stable and has tension during the guiding process, preventing the cable from relaxing.

[0048] The wire slot 50 is in the shape of a circular arc. The diameter of a common mouse cord usually ranges from 2 to 5 mm. In order to accommodate mouse cords with diameters ranging from 2 to 5 mm, the width and depth of the wire slot 50 are both 6 to 8 mm, preferably in the range of 6 to 7 mm, to ensure that the mouse cord can be smoothly placed into the wire slot while having some fixing effect. The inner wall of the wire slot 50 can be smooth or have a soft padding material (such as silicone or soft rubber) to further reduce friction and wear, improving the smooth sliding effect of the mouse cord and prolonging the life of the cable.

[0049] In the preferred implementation of the present application, the wire cover 3 can be fixed by buckling or screwing, which is convenient for users to disassemble the wire cover according to their needs to adjust or replace the mouse wire.

[0050] The bottom of the end cap 4 is provided with a groove 40, the inner profile of which matches the front end profile of the wire seat 5 and the wire cover 3, achieving close fitting and ensuring that the end cap 4 can stably lock the wire seat and the wire cover, enhancing the overall stability of the structure.

[0051] The wire seat 5 and the wire cover 3 are made of lightweight and durable materials such as ABS plastic or nylon, which have good impact resistance and wear resistance, ensuring the strength and durability of the overall structure. The lightweight characteristics of the material make it convenient for users to use for a long time without increasing the burden. The end cap 4 is also made of wear-resistant materials to ensure that the groove 40 will not wear out and become loose after multiple disassembly and assembly.
