Connecting frame 2 5 includes clamping bar 2 51, clamping plate 2 52 and two connecting bars 2 53. Connecting bar 2 53 is fixedly connected to clamping bar 2 51. Both ends of clamping plate 2 52 are slidably connected to the two connecting bars 2 53. Clamping bar 2 51 is rotatably connected to clamping bar 1 41.

[0020] In this embodiment, an operating table 1 is included. The operating table 1 is horizontal, and a groove 11 is formed on the top of the operating table 1. The two sides of the groove 11 are open. A movable frame 2 is rotatably connected to the inner side of the groove 11. The size of the movable frame 2 matches the groove 11. The movable frame 2 includes a connecting rod 21 and two guide rods 22. The length of the connecting rod 21 matches the width of the groove 11, and the thickness of the connecting rod 21 and the guide rods 22 matches the height of the groove 11. When the movable frame 2 is horizontal, the top of the connecting rod 21 and the guide rods 22 are flush with the top of the operating table 1. The two guide rods 22 are fixedly connected to the two ends of the connecting rod 21. The two guide rods 22 are parallel to each other. When the guide rods 22 are located inside the groove 11, the two guide rods 22 are... One side of 2 will contact the inner side of the groove 11. The inner side of the guide rod 22 is provided with a connecting groove 221. The inner side of the connecting groove 221 is movably connected to the limiting frame 3. By sliding the limiting frame 3 into the connecting groove 221, the limiting frame 3 can be flipped over by flipping the movable frame 2. The limiting frame 3 includes a connecting frame 4 and a connecting frame 5. The circuit board can be clamped by the connecting frame 4 and the connecting frame 5. The connecting frame 4 includes a clamping strip 41, a clamping plate 42 and two connecting strips 43. The clamping plate 42 is the same size as the clamping strip 41. The clamping strip 41, the clamping plate 42 and the connecting strips 43 are all made of hard materials such as plastic or metal. The connecting strips 43 are fixedly connected to the clamping strip 41. The two connecting strips 43 are mutually Parallel, connecting strip 43 is connected to the end of clamping strip 41, and connecting strip 43 is perpendicular to clamping strip 41. The two ends of clamping plate 42 are slidably connected to the two connecting strips 43. The distance between clamping plate 42 and clamping strip 41 can be adjusted by sliding clamping plate 42. Connecting frame 5 includes clamping strip 51, clamping plate 52, and two connecting strips 53. Clamping plate 52 has the same dimensions as clamping plate 42. Connecting strip 53 is fixedly connected to clamping strip 51. The two connecting strips 43 are parallel to each other. Clamping strip 51, clamping plate 52, and connecting strip 53 are also made of rigid material. The positions of connecting strip 53 correspond to those of connecting strip 43. The two ends of clamping plate 52 are slidably connected to the two connecting strips 53. The distance between clamping plate 2 52 and clamping strip 2 51 can be adjusted by sliding clamping plate 2 52. When the distance between clamping plate 1 42 and clamping strip 1 41 is slightly less than the width of the circuit board, the circuit board can be placed on clamping plate 1 42 and clamping strip 1 41 to keep it horizontal. At the same time, the electronic components at the bottom of the circuit board will be located between clamping strip 1 41 and clamping plate 1 42 and will not contact the connecting frame 1 4. This keeps the circuit board stable without affecting the electronic components and avoids the circuit board shaking when the maintenance personnel operate it due to the electronic components at the bottom of the circuit board. It also avoids the electronic components being compressed. When the position of clamping plate 2 52 corresponds to clamping plate 1 42, the connecting frame 2 5 is pressed onto the circuit board.The circuit board can be clamped between connecting bracket 4 and connecting bracket 5, without the electronic components on the circuit board contacting connecting bracket 5. This fixes the position of the circuit board without affecting the repair operation, preventing displacement during operation and improving repair convenience. Clamping strip 51 is rotatably connected to clamping strip 41. The angle between connecting bracket 5 and connecting bracket 4 can be adjusted by rotating clamping strip 51 and clamping strip 41. When connecting bracket 5 and connecting bracket 4 are parallel, the circuit board between connecting bracket 5 and connecting bracket 4 can be clamped and limited. When the angle between connecting bracket 5 and connecting bracket 4 increases, the circuit board can be placed or removed.

[0021] The groove 11 has through slots 12 on both sides, and the connecting rod 21 has connecting shaft 211 at both ends. The connecting shaft 211 is rotatably connected to the through slot 12. The dimensions of the through slot 12 and the connecting shaft 211 match. The connection between the connecting shaft 211 and the through slot 12 makes the movable frame 2 flip-up. When the limiting frame 3 is connected to the movable frame 2, if the movable frame 2 is located on the right side of the operating table 1, the connecting frame 4 is located above the connecting frame 5. If the movable frame 2 is flipped to the left side of the operating table 1, the connecting frame 5 is located above the connecting frame 4.

[0022] The top of the clamping bar 41 is provided with a fixed seat 411, and both ends of the fixed seat 411 are provided with connecting shafts 412. The clamping bar 51 is provided with a relief groove 511. The fixed seat 411 is located inside the relief groove 511. Through holes 512 are provided on both sides of the relief groove 511. The connecting shafts 412 are rotatably connected to the through holes 512. The size of the fixed seat 411 and the relief groove 511 are matched. The angle between the connecting frame 4 and the connecting frame 512 can be adjusted by the connection between the connecting shafts 412 and the through holes 512.

[0023] Rubber pads 413 are provided on opposite sides of clamping strip 41 and clamping strip 51, and rubber layers 423 are provided on opposite sides of clamping plate 42 and clamping plate 52. The two rubber pads 413 are positioned opposite each other. When clamping plate 42 and clamping plate 52 are positioned in the same way, the two rubber layers 423 are positioned opposite each other. When the edge of the circuit board is located between clamping strip 41 and clamping strip 51, the circuit board can be clamped and limited by the two rubber pads 413. When the edge of the circuit board is located between clamping plate 52 and clamping plate 42, the circuit board can be clamped by the two rubber layers 423. At the same time, the rubber pads 413 and rubber layers 423 will not damage the circuit board.

[0024] The clamping plate 42 has two connecting grooves 421, and a rubber ring 422 is provided on the inner side of the connecting groove 421. A connecting strip 43 is located on the inner side of the rubber ring 422. The clamping plate 52 has two connecting grooves 521, and a rubber ring 522 is provided on the inner side of the connecting groove 521. A connecting strip 53 is located on the inner side of the rubber ring 522. The friction between the rubber rings 422 and 522 and the connecting strips 43 and 53 allows the clamping plate 42 and clamping plate 52 to maintain their positions after sliding, ensuring the stability of the positions of the clamping plate 42 and clamping plate 52 without affecting the flexibility during adjustment.

[0025] Two connecting strips 43 are provided with a hand plate 431 at the end away from the clamping strip 41, and two connecting strips 53 are provided with a connecting strip 53 at the end away from the clamping strip 51. The hand plate 431 and the hand plate 531 are positioned opposite each other. When the connecting frame 5 is parallel to the connecting frame 4, the bottom of the hand plate 531 will contact the top of the hand plate 431, which makes it easy to move the limiting frame 3 through the hand plate 431 and the hand plate 531. At the same time, the hand plate 431 and the hand plate 531 also make it easy to flip the movable frame 2 and the limiting frame 3.

[0026] In summary, with the help of the above-mentioned technical solution of this utility model, when using this device, firstly, the connecting frame 25 is rotated upward to increase the angle between the connecting frame 25 and the connecting frame 14. Then, the position of the clamping plate 142 is adjusted so that the distance between the clamping plate 142 and the clamping strip 141 is slightly less than the width of the circuit board. Then, the circuit board is placed on the clamping strip 141 and the clamping plate 142, with its two side edges located on the clamping strip 141 and the rubber layer 23, respectively. Then, the direction of the connecting frame 25 and the connecting frame 14 is rotated back to its original position, and at the same time, the position of the clamping plate 252 is adjusted so that it is aligned with the connecting frame 142. With the clamping plate 42 in position, hold the hand plate 431 and the hand plate 531 to push the limiting frame 3 into the inner side of the connecting groove 221, so that the limiting frame 3 is connected to the movable frame 2. When the movable frame 2 is on the right side of the operating table 1, the connecting frame 4 is above the connecting frame 5, and the surface of the circuit board that contacts the connecting frame 4 is on top. When the movable frame 2 is flipped to the left side of the operating table 1, the connecting frame 5 is above the connecting frame 4, and the surface of the circuit board that contacts the connecting frame 5 is on top. Thus, the two sides of the circuit board can be observed and repaired by flipping the movable frame 2.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
