The technical scheme is adopted, and the method has the advantages that: the inserting end of the inserting shaft is in inserting fit with the slot in the torque meter to realize the fixed connection of the inserting end and the torque meter, and the inserting shaft is ensured not to fall off from the torque meter to cause detection failure when a sealing element to be tested is detected.

The utility model discloses further set up: insert the axial periphery wall and go up the ring and be provided with the external screw thread, the ring is provided with the internal thread on the trompil internal perisporium, the fixed connection of first fixed disk and second fixed disk is realized with external screw thread screw-thread fit to the internal thread.

The technical scheme is adopted, and the method has the advantages that: the connection strength between the inserting shaft and the inserting groove is further improved due to the arrangement of the external thread and the internal thread.

The utility model discloses further set up: the mounting is the locking bolt, bearing fixing base top is seted up and is supplied locking bolt male through-hole, the through-hole sets up with locking bolt screw-thread fit.

The technical scheme is adopted, and the method has the advantages that: can contradict on the bearing ring periphery wall when locking bolt screws in, ensure the stability of bearing ring in spacing hole, further guarantee that the bearing ring can not drop from spacing hole and lead to detecting the failure when detecting the moment of torsion of waiting to test the sealing member.
