[0019] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0020] In the description of the present invention, unless otherwise specified, "multiple" means two or more; the terms "upper", "lower", "left", "right", "inner", "outer", "front end", "rear end", "head", "tail" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0021] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] See also Figures 1 to 4 The utility model provides a technical solution: a circuit board testing tool, including a tester body 1 and a base 2, a plurality of positioning rods 3 are fixed on the top surface of the base 2, mounting plates 4 are fixed on both sides of the base 2, a cylinder 5 is fixed on the bottom surface of the mounting plate 4, the output end of the cylinder 5 passes through the interior of the mounting plate 4 and is fixed with a connecting plate 6, a movable plate 7 is fixed between the two connecting plates 6, a plurality of positioning holes 9 are opened on the top surface of the movable plate 7, a plurality of mounting grooves 10 are also opened on the top surface of the movable plate 7, a guide block 11 is arranged on the inner side of the mounting groove 10, the lower ends of the plurality of guide blocks 11 are fixedly connected to the top surface of the base 2, and the plurality of guide blocks 11 are fixedly connected to the top surface of the base 2. A guide groove 12 is provided on one side, and the movable plate 7 is also provided with a plurality of clamping plates 13. Four connecting rods 14 are fixed on one side of the plurality of clamping plates 13. The outer side of the connecting rod 14 is slidably connected with a support 15. The lower end of the support 15 is fixedly connected to the top surface of the movable plate 7. A slider 8 is fixed between two adjacent connecting rods 14. The outer side of the slider 8 is slidably connected to the inner side of the guide groove 12. The cylinder 5 is perpendicular to the movable plate 7. The position of the positioning hole 9 corresponds to the position of the positioning rod 3. The plurality of guide blocks 11 are arranged in a rectangular shape. The guide groove 12 is divided into an inclined section and a vertical section. The plurality of clamping plates 13 are arranged in a rectangular shape. The slider 8 is a cylindrical structure.

[0023] After placing the circuit board on the movable plate 7, start the cylinder 5, and the cylinder 5 drives the movable plate 7 to move upward through the connecting plate 6. During this process, the slider 8 on the connecting rod 14 slides along the inner side of the guide groove 12, and passes through the inclined section on the guide groove 12, forcing the slider 8 to drive the connecting rod 14 to move toward the middle of the movable plate 7. The connecting rod 14 pushes the clamping plate 13 to move toward the middle of the movable plate 7. Since the clamping plates 13 on all sides move toward the middle of the movable plate 7 at the same time, the circuit board is gradually centered, so that the positioning holes on the circuit board are aligned with the positioning holes 9 on the movable plate 7. As the movable plate 7 continues to move, the slider 8 enters the vertical section on the guide groove 12, and no longer moves in the horizontal direction, so that the clamping plate 13 fixes the movable plate 7. At the same time, the positioning rod 3 on the support 2 sequentially passes through the positioning holes 9 on the movable plate 7 and the positioning holes on the circuit board to achieve precise positioning. Through the above process, the existing circuit board test fixture is solved, and the problem that the positioning holes on the circuit board need to be aligned with the positioning pins on the test fixture for positioning, and rapid alignment requires a certain amount of time for practice.

[0024] Specific usage and function of this embodiment: After the circuit board is placed on the movable plate 7, the utility model starts the cylinder 5, and the cylinder 5 drives the movable plate 7 to move upward through the connecting plate 6. During this process, the slider 8 on the connecting rod 14 slides along the inner side of the guide groove 12, and passes through the inclined section on the guide groove 12, forcing the slider 8 to drive the connecting rod 14 to move toward the middle of the movable plate 7. The connecting rod 14 pushes the clamping plate 13 to move toward the middle of the movable plate 7. Since the clamping plates 13 on all sides move toward the middle of the movable plate 7 at the same time, the circuit board is gradually centered, so that the positioning holes on the circuit board are aligned with the positioning holes 9 on the movable plate 7. As the movable plate 7 continues to move, the slider 8 enters the vertical section on the guide groove 12 and no longer moves in the horizontal direction, so that the clamping plate 13 fixes the movable plate 7. At the same time, the positioning rod 3 on the support platform 2 passes through the positioning holes 9 on the movable plate 7 and the positioning holes on the circuit board in sequence to achieve precise positioning.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
