[0013] The utility model has at least the following beneficial effects: 1. During installation, the sensor body is inserted into the pipeline, and the limit block is inserted into the limit groove, so that the sensor body is limited in the pipeline. At this time, the six-sided sleeve is rotated, and the six-sided sleeve rotates on the sensor body through the sealed bearing.
