[0002] In the field of electronic equipment repair, the repair of small circuit boards (such as mobile phone motherboards and small daughterboards of computer motherboards) is very common. When repairing these small boards, they need to be reliably secured so that repair personnel can perform operations such as soldering, testing, and component replacement. However, existing securing methods and carriers have many problems: 1. Poor versatility: Most current fixtures are designed for small repair boards of specific sizes and models, making it difficult to achieve universal compatibility with boards of varying sizes and shapes. When faced with boards of different specifications, repair personnel often need to change to different fixtures, which is not only cumbersome but also increases repair costs and time.

[0003] 2. Insufficient Fixture Stability: Some fixtures fail to provide adequate support and fixation when securing small boards. During maintenance, the boards are prone to wobbling and displacement, which not only affects the accuracy of maintenance operations but may also damage components on the boards during welding and other operations, reducing the success rate and yield of repairs.

[0004] 3. Poor ease of operation: Some existing fixing fixtures have complex structures, making it inconvenient to place and remove small plates, which increases the difficulty and time consumption of maintenance personnel; moreover, they are not flexible and convenient enough when adjusting the fixing method to adapt to different maintenance needs.

[0005] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a new type of fixing clamp for maintenance boards with a new structure, which would make it more valuable for industrial use. Utility Model Content

The transverse and longitudinal T-shaped grooves intersect perpendicularly to form a grid structure. Several independent first sliding blocks are slidably connected within each transverse T-shaped groove, and several independent second sliding blocks are slidably connected within each longitudinal T-shaped groove. First and second sliding blocks are respectively connected to first and second locking bolts for locking their current positions. First and second fixed arms are respectively connected to the first and second sliding blocks, and each of the first and second fixed arms is connected to an elastic clamp.

[0008] Preferably, in the aforementioned fixing clamp for repair boards, the fixing base is integrally molded from engineering plastic and has a rectangular flat plate structure.

[0009] Preferably, in the aforementioned fixing clamp for repairing small boards, the bottom of the fixing base is connected to a support foot for adjusting the height, and the support foot is threadedly connected to the four corners of the fixing base.

[0010] Preferably, in the aforementioned fixing clamp for repairing small boards, the elastic clamp is made of rubber or silicone material.

[0011] Preferably, in the aforementioned fixing clamp for repairing small boards, the first fixing arm and the second fixing arm are connected to their respective sliding blocks via universal joints.

[0012] Preferably, in the fixing fixture for the repair board, the first sliding block and the second sliding block are provided with positioning holes that match the mounting holes of the repair board, and positioning pins are connected to the positioning holes.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0021] Example 1 like Figure 1 and Figure 2As shown, a fixing clamp for repairing small boards includes a fixing base 1. The fixing base 1 has several equidistant transverse T-shaped grooves 3 on its transverse side and several equidistant longitudinal T-shaped grooves 4 on its longitudinal side. The transverse T-shaped grooves 3 and the longitudinal T-shaped grooves 4 intersect perpendicularly and form a grid structure. Several independent first sliding blocks 5 are slidably connected in each transverse T-shaped groove 3, and several independent second sliding blocks 6 are slidably connected in each longitudinal T-shaped groove 4. A first locking bolt 7 and a second locking bolt 8 for locking the current position of the sliding block are respectively connected to the first sliding block 5 and the second sliding block 6. A first fixing arm 9 and a second fixing arm 10 are respectively connected to the first sliding block 5 and the second sliding block 6. An elastic clamp 11 is connected to both the first fixing arm 9 and the second fixing arm 10.

[0022] In this embodiment, the fixed base 1 is integrally molded from engineering plastic and has a rectangular flat plate structure. It possesses good flatness and rigidity, providing a stable supporting foundation for the maintenance board.

[0023] Meanwhile, the bottom of the fixed base 1 is connected to a support foot 2 for height adjustment. The support foot 2 is threaded to the four corners of the fixed base and fixed to the main body of the vehicle through the threaded connection. The level and height of the main body of the vehicle can be adjusted by rotating the support foot according to the actual maintenance workbench conditions and needs.

[0024] In this embodiment, the elastic clamp is made of rubber or silicone, and the end of the elastic clamp that contacts the product is provided with anti-slip stripes. It has a certain degree of elasticity and friction, which can effectively prevent scratches on the surface of the repair board while firmly clamping the board (product).

[0025] Example 2 Based on Embodiment 1, the first fixed arm 9 and the second fixed arm 10 are connected to their respective sliding blocks via universal joints 12. The first sliding block 5 and the second sliding block 6 are provided with positioning holes 13 that match the mounting holes of the maintenance board, and positioning pins 14 are connected to the positioning holes 13.

[0026] Each slider has a vertically mounted adjustable angle and height fixed arm on top. The fixed arm is connected to the slider via a universal joint, allowing for 360-degree rotation and multi-angle adjustment. The top of the fixed arm is equipped with a flexible clamp, which can effectively prevent scratches on the surface of the repair board while firmly clamping the board.

[0027] Multiple positioning holes are provided on the edge of the sliding block, and the spacing of the positioning holes matches the mounting hole spacing of common repair boards. The board can be quickly positioned on the carrier using positioning pins. At the same time, multiple magnetic points are also provided on the sliding block. The magnetic points have built-in strong magnets that can attract repair boards with metal parts, further enhancing the fixing effect.

[0028] A foldable magnifying glass holder is also provided on one side of the fixed base. The holder is equipped with a high-magnification magnifying glass, which makes it easier for maintenance personnel to observe the fine components and circuits on the small board and improves the accuracy of maintenance operations.

[0029] The working principle of this utility model is as follows: 1. Based on the actual environment of the maintenance work, place the fixed base on a suitable maintenance workbench, and adjust the level of the vehicle body by rotating the support feet at the four corners to ensure that the vehicle is in a stable state.

[0030] 2. Fixing Structure Adjustment: Based on the size and shape of the small board to be repaired, loosen the locking bolts of the slider inside the T-shaped slide groove, and slide the slider to a suitable position (the suitable position is the product matching position, which is implemented by the operator), so that the fixing arm is in the position where the product (small board) needs to be fixed. Then, adjust the angle of the fixing arm through the universal joint so that it is perpendicular to the surface of the small board or at a suitable angle. Then, adjust the height of the fixing arm according to the thickness of the small board so that the elastic clamp can just clamp the small board. Finally, tighten the locking bolts to fix the position of the slider and the fixing arm.

[0031] 3. Small plate positioning and fixing: Place the small repair plate on the sliding block, aligning the mounting holes of the small plate with the positioning holes on the edge of the sliding block. Then insert the positioning pin to complete the initial positioning of the small plate. For small plates with metal parts, the magnetic attraction points on the sliding block can be used for further adsorption and fixing. Then, operate the fixing arm to make the elastic clamp hold the edge of the small plate or a suitable position, ensuring that the small plate is firmly fixed on the carrier.

[0032] 4. Maintenance Operations: After the small board is fixed, the magnifying glass bracket on the carrier can be unfolded according to maintenance needs. The position and angle of the magnifying glass can be adjusted to clearly observe the components and circuits on the small board, and maintenance operations such as soldering, testing, and component replacement can be performed.

[0033] 5. Post-use procedures: After completing the maintenance of the repair board, release the spring clamp and pull out the locating pin to remove the board from the carrier. Finally, return the slider and fixing arm to their initial positions as needed for next use.

[0034] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0035] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0036] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0037] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
