That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model is an electrostatic protection plate for a test board, comprising a protection plate 1, wherein mounting holes are provided on the four corners of the protection plate 1, a rotating shaft 4 is movably connected in the mounting holes, a first adjusting block 11 is installed at one end of the rotating shaft 4, a screw hole is provided on the bottom surface of the first adjusting block 11, a stud 10 is threadedly connected in the screw hole, a second adjusting block 5 is installed at the other end of the stud 10, an inserting shaft 6 is installed at one end of the second adjusting block 5 away from the stud 10, a clamping mechanism for clamping and fixing with the test board is installed on one side of the inserting shaft 6, a notch is provided on one side of the protection plate 1 at the connection socket of the test board, a positioning mechanism for pressing the connection socket is movably installed in the notch;

[0021] The first adjusting block and the second adjusting block have a hexagonal structure on the outside, so that a wrench can be sleeved on the first adjusting block and the second adjusting block, which facilitates adjustment thereof.

[0022] In this embodiment, the clamping mechanism includes a ball 7 and a first compression spring 8. A groove is provided on one side surface of the insertion shaft 6. A part of the ball 7 extends into the interior of the groove, and the other part protrudes to the outside. The first compression spring 8 is arranged inside the groove, one end of the first compression spring 8 is installed on the ball 7, and the other end is installed on the inner wall surface of the groove.

[0023] In this embodiment, the positioning mechanism includes a pressure plate 2 and a plurality of second compression springs. The pressure plate 2 is arranged in the notch. The pressure plate 2 is arranged in a "U"-shaped structure. Both ends of the pressure plate 2 are bent outward to form a connecting portion 3. Positioning openings are vertically provided at both ends of the notch. Positioning strips 9 are provided in the positioning openings. One side of the positioning strips 9 is installed on the pressure plate 2. The second compression springs are installed between the protective plate 1 and the connecting portion 3, so that the pressure plate can only move up and down along the positioning opening, thereby preventing the pressure plate from detaching from the notch.

[0024] In this embodiment, the protection plate 1 is made of antistatic polyvinyl chloride material and can play an antistatic function.

[0025] In this embodiment, the inner ring surface of the mounting hole is provided with a ring-shaped positioning groove, and the outer ring surface of the rotating shaft 4 is installed with a positioning ring. The positioning ring is movably arranged in the positioning groove, so that the rotating shaft can only rotate idly in the mounting hole, thereby avoiding separation from the mounting hole.

[0026] When in use, first adjust the height of the protection plate according to the height of the electronic components on the test board. When adjusting, prepare two wrenches, one wrench is put on the first adjustment block, and the other is put on the second adjustment block. After turning the wrench outside the first adjustment block, the first adjustment block can move up or down along the stud until the height of the protection plate is higher than the height of the electronic components;

[0027] After the above is completed, the protection board can be directly held by hand, and the plug shaft can be inserted into the holes at the four corners of the test board. As the plug shaft is inserted, the ball can be pressed into the inside of the groove. After the ball passes through the test board, the elastic energy of the first compression spring pushes the ball outward, so that the ball is stuck on the bottom surface of the test board, thereby clamping and fixing the protection board on the test board to protect the electronic components on the test board;

[0028] Among them, after the protection plate is fixed, the pressure plate is pressed on the top surface of the connection socket by the elasticity of the second compression spring, which can press the connection socket tightly and avoid the connection socket from loosening during the test plugging process.

[0029] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
