Further, as can be seen from fig. 2, the deblocking structure 2 includes a deblocking pin, a connecting sleeve and a adapter, the deblocking pin connects the upper connector 1 with the connecting sleeve, and the adapter is in threaded connection with the connecting sleeve. When the device is used, the upper joint and the connecting sleeve are relatively displaced through the drill rod lifting device, and the unsealing pin is sheared off. The device realizes the deblocking action, the liquid under pressure pushes the valve, the liquid inlet valve spring is compressed, the capsule liquid inlet channel is opened, the liquid under pressure expands the capsule, when the liquid pressure is reduced to zero, the liquid inlet valve closes the liquid inlet channel under the action of the spring, so that the device completes the sealing action.
