The tool includes a valve cover piece 1, a rubber cap valve 2, a test valve body 3, and a sealing ring 5. The rubber cap valve 2 is arranged inside the test valve body 3, and the sealing ring 5 is arranged on the valve cover piece 1. Putting the rubber cap valve 2 into the test valve body 3 and covering the valve cover piece 1 forms a detachable detection tool as a whole. The sealing ring 5 and the valve cover piece 1 can ensure the airtightness of the tool.
