A mounting groove 14 is provided on the sliding seat 9, and a U-shaped groove 15 is provided in the mounting groove 14. There are two U-shaped grooves 15, and the movable shaft 16 is movably arranged in the U-shaped groove 15. That is, when the rotating plate 12 rotates, the movable shaft 16 slides along the U-shaped groove 15, driving the sliding seat 9 to move. This design can drive the sliding seat 9 to slide while the second clamping seat 3 slides, so that the clamping plate 10 automatically detaches from the PCB board 4.

[0026] Preferably, the movable shaft 16 is rotatably connected to the rotating plate 12, which can reduce friction.

[0027] In another embodiment of the present invention, a torque spring is provided on the rotating shaft 11, and the elastic force of the torque spring is used to drive the rotating plate 12 to rotate and reset, that is, when the rotating plate 12 is released from the squeezing of the notch 13, the torque spring drives the rotating plate 12 to rotate and reset.

[0028] In another embodiment of the present invention, a slope 21 is provided on the pressing plate 10 so that the pressing plate 10 is squeezed to move upward along the sliding seat 9 to adapt to PCB boards 4 of different thicknesses and to press and fix PCB boards 4 of different thicknesses.

[0029] In another embodiment provided by the utility model, a first slider 6 is provided on the second clamping seat 3, a first slide groove 5 adapted to the first slider 6 is provided on the fixed seat 1, a first elastic member 7 is provided in the first slide groove 5, one end of the first elastic member 7 is fixedly connected to the first slider 6, and the other end is fixedly connected to the first slide groove 5, the first elastic member 7 is a compression spring, and its elastic force is used to drive the second clamping seat 3 to slide and reset, thereby realizing automatic clamping of the PCB board 4, and the elastic force of the first elastic member 7 makes the second clamping seat 3 press against the PCB board 4, thereby realizing the clamping and fixation of the PCB board 4.

[0030] In another embodiment provided by the utility model, a second slide groove 17 is opened in the through groove 8, and the sliding seat 9 slides along the second slide groove 17. A second elastic member 18 is arranged in the second slide groove 17. One end of the second elastic member 18 is connected to the sliding seat 9, and the other end is connected to the second slide groove 17. The second elastic member 18 is a compression spring, and its elastic force is used to drive the sliding seat 9 to slide and reset.

[0031] In another embodiment provided by the utility model, a third slide groove 19 is provided on the sliding seat 9, the clamping plate 10 slides vertically along the third slide groove 19, and a third elastic member 20 is provided in the third slide groove 19, one end of the third elastic member 20 is fixedly connected to the clamping plate 10, and the other end is fixedly connected to the third slide groove 19, and the third elastic member 20 is a compression spring, and its elastic force is used to drive the clamping plate 10 to clamp and fix the PCB board 4.

[0032] When the second clamping seat 3 is in actual use, the second clamping seat 3 is pulled to make the second clamping seat 3 slide in the direction away from the first clamping seat 2. While the second clamping seat 3 slides, the rotating plate 12 moves synchronously in the direction of the notch 13. When the rotating plate 12 is against the inner wall of the notch 13, the second clamping seat 3 continues to slide, and the rotating plate 12 is squeezed by the inner wall of the notch 13 and rotates. During the rotation of the rotating plate 12, the movable shaft 16 slides along the U-shaped groove 15, driving the sliding seat 9 to slide along the second sliding groove 17, that is, the sliding seat 9 drives the clamping plate 10 to slide and shrink into the through groove 8 to facilitate the placement of the PCB board 4. Then, the PCB board 4 is placed between the first clamping seat 2 and the second clamping seat 3 close to the first clamping seat 2, and then the second clamping seat 3 is released. At this time, the first elastic member The elastic restoring force of 7 drives the second clamping seat 3 to slide and reset. During the sliding and resetting process of the second clamping seat 3, the elastic restoring force of the torque spring drives the rotating plate 12 to rotate and reset. At the same time, the movable shaft 16 slides along the U-shaped groove 15, driving the sliding seat 9 to slide toward the PCB board 4. In this process, the elastic force of the second elastic member 18 also drives the sliding seat 9 to slide and reset. When the clamping plate 10 moves to the position of the PCB board 4, the inclined surface 21 on the clamping plate 10 is squeezed by the PCB board 4 and moves upward along the third slide groove 19 to adjust the thickness of the PCB board 4. When the second clamping seat 3 slides to the position of the PCB board 4, the PCB board 4 is clamped. At the same time, the clamping plate 10 presses the top of the PCB board 4 to fix the PCB board 4.

[0033] When the PCB board 4 needs to be removed, similarly, the second clamping seat 3 is pulled away from the PCB board 4. At the same time, when the second clamping seat 3 moves, the pressing plate 10 is driven by the rotating plate 12 to slide and shrink into the through groove 8, so as to be separated from the PCB board 4 and take out the PCB board 4.
