Receiving grooves 6 are provided inside the outer fixing ring 5 at the front and back, and a compression spring 7 is fixed to one side of the inner part of the receiving groove 6. The left side of the receiving groove 6 is a closed structure and the right side is an open structure, and the compression spring 7 is fixed inside the receiving groove 6 and is located on one side of the opening. A flip plate 8 is hinged inside the receiving groove 6, and the flip plate 8 is connected to the compression spring 7. A limiting ear 9 is fixed to the right side of the flip plate 8 and is engaged with the sensor line connector 3. On the right wall, the flip plate 8 and the limiting ear 9 are an integrated structure, and the flip plate 8 and the limiting ear 9 are combined into an L-shaped structure, a positioning ring 11 is threadedly connected to the external fixing ring 5, and the positioning ring 11 is pressed onto the flip plate 8, the positioning ring 11 and the right side wall of the external fixing ring 5 are located on the same horizontal plane, and the positioning ring 11 has the same width as the external fixing ring 5, the outer wall of the external fixing ring 5 is provided with external thread teeth 10, the inner wall of the positioning ring 11 is provided with an internal thread groove 12 adapted to the external thread teeth 10, and the internal thread groove 12 is threadedly connected to the external thread teeth 10.
