[0026] When in use, the starting motor 8 drives the transmission belt 9 to rotate through the pulley, so that the upper end of the transmission belt 9 drives the rotating shaft 21 to rotate, so that the gear 10 above the rotating shaft 21 rotates. Since the gear 10 is meshed with the first rack 11 and the second rack 12, the first rack 11 slides inside the body 1. Since the first rack 11 and the through hole 14 inside the body 1 are arranged alternately, and the second rack 12 slides on the fixing rod 15, the baffle 16 below is driven to move, so that the baffle 16 slides inside the body 1 and then opens. At this time, when the coupler body 2 is in use, heat can be dissipated through the upper moving plate 13 and the through hole 14 inside the body 1. At the same time, when sealing is required during use, the card slot below the cover plate 20 can be aligned with the card block 19 above the body 1 and pressed in, so that the card block 19 and the block 18 connected by the spring 17 inside the cover plate 20 are engaged. At the same time, since a rubber gasket is provided at the connection position between the cover plate 20 and the body 1, the sealing is better.

[0028] First, when using, the two sides of the body 1 are connected to the connector 3 through threads. At this time, turn the handles on both sides of the body 1, so that the handles drive the screw rod 4 to rotate, and the rotation of the screw rod 4 drives the moving block 5 to move at the same time, so that the moving block 5 moves in the slide groove inside the clamping block 6, so that the clamping block 6 slides over the slide rod 7, so that the front end of the clamping block 6 contacts the connector 3, so that the connection between the connector 3 and the body 1 is more stable.

[0029] Working principle: When using a high-sealing coupler with high connection stability, first use the body 1 and connect the two sides through threads and the connector 3. At this time, turn the handles on both sides of the body 1, so that the handles drive the screw 4 to rotate, and the screw 4 rotates and drives the moving block 5 to move at the same time, so that the moving block 5 moves in the slide groove inside the clamping block 6, so that the clamping block 6 slides over the slide rod 7, so that the front end of the clamping block 6 contacts the connector 3, so that the connection between the connector 3 and the body 1 is more stable. When in use, start the motor 8 to drive the transmission belt 9 to rotate through the pulley, so that the upper end of the transmission belt 9 drives the rotating shaft 21 to rotate, so that the gear 10 above the rotating shaft 21 rotates. The first rack 11 is meshed with the through hole 14 in the body 1, and the second rack 12 slides on the fixing rod 15, and drives the baffle 16 below to move, so that the baffle 16 slides inside the body 1 and opens after the baffle 16 is opened. At this time, when the coupler body 2 is in use, the heat can be dissipated through the upper movable plate 13 and the through hole 14 in the body 1. At the same time, when sealing is required during use, the card groove under the cover plate 20 can be aligned with the card block 19 above the body 1 and pressed in, so that the card block 19 and the baffle 18 connected by the spring 17 inside the cover plate 20 are engaged. At the same time, since a rubber gasket is provided at the connection position between the cover plate 20 and the body 1, the sealing is better.
