[0039] Working principle; first, by controlling the first air cylinder 51, the limiting frame 532 is brought into contact with the water-cooled plate 2, then the second motor 526 is started to drive the rotating shaft 527 to rotate the second bevel gear 537, so as to drive the first bevel gear 536 to synchronously rotate the bidirectional screw rod 533, which can drive the two clamping plates 535 to move towards each other, and finally can clamp the water-cooled plate 2 by the two clamping plates 535;

[0041] Embodiment 4:

[0042] In embodiment 3, the two clamping plates 535 need to be separated from the water-cooling plate 2 after the water-cooling plate 2 is flipped, so as to avoid the influence of the clamping plates 535 on the observation of the leakage point of the water-cooling plate 2, and once the clamping plates 535 are separated from the water-cooling plate 2, the water-cooling plate 2 will sink, which is not convenient for the secondary flipping of the water-cooling plate 2;
