Connector for fixing drilling machine and test-while-drilling short circuit

The utility model provides a connector for fixing a drilling machine and testing while drilling short circuit, which comprises a first connecting part and a second connecting part which are detachable and form an accommodating cavity; a limiting hole is formed in one end of the containing cavity and used for limiting displacement of the rotating clamping piece in the rotating direction. And the other end of the accommodating cavity is used for limiting the displacement of the test-while-drilling pup joint in the rotating direction, so that the test-while-drilling pup joint and a drilling machine are fixed through the connector, and the efficiency and the safety of the process that the test pup joint is connected with a new rotating rod are ensured. 本实用新型提供一种用于固定钻机及随钻测试短接的连接器，该连接器包括：可拆分的第一连接部件和第二连接部件，所述第一连接部件和所述第二连接部件组成容纳腔；所述容纳腔的一端上设置有限位孔，所述限位孔用于限制所述旋转卡件在旋转方向发生的位移；所述容纳腔的另一端用于限制所述随钻测试短接在旋转方向发生的位移，从而通过连接器将随钻测试短接与钻机固定，保证了测试短接连接新转杆过程的效率和安全性。
