Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0020] It should be noted that the terms "first", "second", etc. in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so as to describe the embodiments of the utility model described here. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0021] In the present invention, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inside", "outside", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

For example, the term "on" may also be used to express a certain dependency or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in this utility model can be understood according to the specific circumstances. In addition, the term "plurality" should mean two or more than two.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other. Figure 1-Figure 5 The utility model is described in detail in conjunction with the embodiments.

[0024] A support for processing a circuit board includes a workbench 1, the workbench 1 includes a top plate 8, four support columns 9 are fixedly arranged on the bottom wall of the top plate 8 for supporting the top plate 8 during operation, a plurality of threaded holes 2 are evenly arranged on the top plate 8, the plurality of threaded holes 2 penetrate the top plate 8, and the plurality of threaded holes 2 are distributed in equally divided circular rings that are evenly enlarged from the center to the outside.

[0025] The threaded holes 2 are evenly distributed in an annular pattern, which makes it easier for various special-shaped circuit boards to find threaded holes 2 that fit the fixed shape. Figure 3 For the three special-shaped circuit board bodies 11, the circular one can find the threaded holes 2 closest to the four outer end points for subsequent fixation, and the square or elliptical one can also find several more suitable threaded holes 2 for subsequent fixation.

[0026] The threaded hole 2 is internally threaded with a threaded rod 3, and the bottom end of the threaded rod 3 is threaded with a nut 10, which can fix the threaded rod 3 on the threaded hole 2. By moving the threaded rod 3 up and down, the circuit boards of different thicknesses can be fixed.

[0027] A universal coupling 4 is movably arranged at the top of the threaded rod 3. The universal coupling 4 is rotatably arranged at the center of the top wall of the threaded rod 3. A plurality of buckle grooves 5 are arranged around the universal coupling 4, and the plurality of buckle grooves 5 are evenly distributed around the universal coupling 4 in a circular shape.

[0028] The universal coupling 4 can be rotated up, down, left, and right at will. Since a pressure rod 6 is fixedly provided on the outer wall of the universal coupling 4, the movable pressure rod 6 can be rotated around it at will under the drive of the universal coupling 4, and is connected and fixed according to the shape of the circuit board and the matching buckle groove 5.

[0029] The bottom wall of the pressure rod 6 is provided with a buckle head 7, which can be buckled with any buckle groove 5. The buckle head 7 and the buckle groove 5 are adapted to each other and use the buckle buckle structure in the prior art to achieve quick connection and quick separation.

[0030] The shortest distance between two adjacent pressure rods 6 after rotation is greater than the added length of the two pressure rods 6, and the two pressure rods 6 can rotate with each other without colliding, but are not too far apart to ensure that they do not touch each other when rotating.

[0031] By rotating the pressing rod 6 that matches the shape of the circuit board body 11, the pressing rod 6 can limit and fix the top wall of the circuit board body 11, and the threaded rod 3 can limit and fix the side wall of the circuit board body 11. When the circuit board needs to be taken, the pressing rod 6 can be quickly raised to make the buckle head 7 away from the buckle groove 5 and rotated to the end away from the circuit board, so as to facilitate the quick taking of the circuit board.

[0032] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
