The working principle is as follows: when the device works, the convex plate 12 at the edge of the threaded rod 11 at the bottom of the transmitter body 1 corresponds to the rectangular through groove 10, the convex plate 12 penetrates into the bearing cover 4, then the transmitter body 1 is rotated to enable the threaded rod 11 to be in threaded connection with the threaded hole 14, the bottom of the transmitter body 1 is tightly attached to the surface of the bearing cover 4, at the moment, the trapezoidal block 17 can be moved towards the direction close to the transmitter body 1 through the pull plate 7, the inclined surface of the trapezoidal block 17 can push the bottom end of the ejector rod 15 to move upwards, then the position of the pull plate 7 is fixed through the positioning mechanism, the U-shaped stop rod 13 is clamped between the convex plate 12 and the bearing cover 4 to prevent the threaded rod 11 from falling off from the inside of the threaded hole 14, the installation is firmer, when the device needs to be disassembled, the limitation on the pull plate 7 is removed through the positioning mechanism, the trapezoidal block 17 can move towards the direction far away from the transmitter body 1 under the action of the stretching spring fixedly connected with the trapezoidal block 17, the ejector rod 15 moves downwards under the action of an extension spring fixedly connected with the guide block 19, so that the U-shaped stop lever 13 is separated from the space between the convex plate 12 and the bearing cover 4, the threaded rod 11 can be directly screwed out of the inner part of the threaded hole 14 at the moment, then when the thread on the threaded rod 11 is separated from the outer port of the threaded hole 14, the threaded rod 11 can be directly rotated to the position where the convex plate 12 corresponds to the rectangular through groove 10, and the threaded rod 11 can be directly pulled out of the inner part of the threaded hole 14 at the moment, so that the transmitter body 1 is separated from the bearing cover 4;
according to the invention, the mode that the threaded rod 11 is in threaded connection with the threaded hole 14 is adopted, and the adsorption force of the magnet 3 and the bearing cover 4 is combined, so that the transmitter body 1 is preliminarily fixedly connected on the bearing cover 4, and then the convex plate 12 is matched with the U-shaped stop lever 13, so that the threaded rod 11 can be prevented from being separated from the inside of the threaded hole 14, the transmitter body 1 can be always in close contact with the surface of the bearing cover 4, and the accuracy of measured data is ensured;
meanwhile, the transmitter body 1 can be firmly installed from the outside without disassembling the bearing cover 4, and the installation is fast and firmer.
