[0037] like Figure 2 As shown, there are two groups of moving blocks 1 53, and the one near the twist handle 51 is hinged to the hinge rod 54. When the twist handle 51 rotates, the two groups of moving blocks 1 53 will drive the pressure plate 1 57 to move relative to each other. At the same time, when the moving block 1 53 moves, the hinge rod 54 will pull the moving block 2 56 to move, and the pressure plate 2 582 will move, so as to clamp the PCB board body 4.

[0038] In the embodiment of the utility model, in order to further clamp the PCB board body 4, specifically, the moving block 56 is provided with a groove 561, the groove 561 is slidably connected with the slider 55, the moving block 56 is slidably connected with the card block 562, the outer wall of the card block 562 is fixedly connected with a spring 563, the end of the spring 563 away from the card block 562 is slidably connected with the inner wall of the moving block 56, the card block 562 is provided with a through groove 566, the through groove 566 is slidably connected with an inclined rod 564, the outer wall of the inclined rod 564 is fixedly connected with one end of the spring 565, the other end of the spring 565 is fixedly connected with the inner wall of the moving block 56, and the moving plate 58 is provided with a through groove 566.

At the same time, the extrusion rod 584 will squeeze the sliding rod 585, so that the sliding rod 585 slides downward, thereby releasing the limit between the slider 55 and the moving block 2 56, and then continue to rotate the twist handle 51. At this time, the hinged rod 54 drives the slider 55 to slide in the groove 561, and then the pressure plate 1 57 will continue to move toward the PCB board body 4, thereby clamping the PCB board body 4 again.
