The back plate 12 is provided with a guide rod 3, and the top end of the guide rod 3 is movably arranged on the frame 1 through a bearing. When the telescopic rod of the lifting cylinder 2 extends downward, it can drive the back plate 12 and the clamping mechanism to move downward, and the guide rod 3 guides during the movement process to improve the stability of the movement process.

[0027] The water tank 14 is arranged below the frame 1, and water is contained in the water tank 14. The lifting cylinder 2 can drive the back plate 12 and the clamping mechanism to move up and down, so that the back plate 12 and the clamping mechanism extend into the water tank 14, enabling the product 6 clamped by the clamping mechanism to be submerged in water for leakage detection of the product 6. The product 6 clamped by the present utility model is mainly a multi-channel valve with three interfaces.

[0030] The sliding pallet 11 is slidably arranged directly below the first sealing seat 5, and a placement space for the product 6 is left between the sliding pallet 11 and the first sealing seat 5; the sliding pallet 11 is slidable and can slide downward under the pressure of the product 6 after the product 6 is placed.

[0031] The two plugging units are symmetrically arranged on both sides of the axis of the clamping cylinder 4; the two plugging units are oppositely arranged and jointly plug the interfaces on both sides of the product 6.

[0032] The plugging unit includes: a pressing plate 7, a second sealing seat 8, a clamping jaw 9 and a sliding connecting piece 13; the pressing plate 7 is movably arranged on the back plate 12 through the sliding connecting piece 13, and the second sealing seat 8 is arranged on the pressing plate 7; air holes and air channels are left on the pressing plate 7, and the air holes on the pressing plate 7 are connected to a gas source.

After the product 6 is removed, the sliding pallet 11 loses pressure, and the torsion spring 10 drives the sliding connecting piece 13, the pressing plate 7, the second sealing seat 8, the clamping jaw 9, and the sliding pallet 11 to reset.
