In this embodiment, this displacement sensor connecting device is when using, earlier with ring portion 10 fix ground cover locate displacement sensor 30's the outside, then laminate backup pad 20 in tensioning jack 40's outer wall, and the axis of duplex winding tensioning jack 40 rotates backup pad 20, so that cardboard 22 moves into inside draw-in groove 42 on tensioning jack 40, utilize the cooperation of cardboard 22 and draw-in groove 42 can restrict displacement sensor 30's axial position, magnetic path 21 is connected with the magnetism of tensioning jack 40 and can restrict displacement sensor 30's radial position simultaneously, this displacement sensor connecting device with displacement sensor 30 detachably joint in tensioning jack 40, make displacement sensor 30's dismouting more convenient, have the advantage that the flexibility is good.

In this embodiment, optionally, the ring portion 10 is adapted to the shape of the displacement sensor 30, as an example, the ring portion 10 is configured to be a circular ring shape as a whole, the ring portion 10 is fittingly sleeved on the outer side of the displacement sensor 30, the ring portion 10 can be fixed to the displacement sensor 30 by screws, and in order to ensure the overall stability of the displacement sensor 30, two of the connecting devices may be disposed on the displacement sensor 30 at intervals.

Further, the support plate 20 is configured to be an arc plate as a whole, the support plate 20 is fixedly connected to the outside of the ring portion 10, and as an example, the support plate 20 and the ring portion 10 are integrally formed, and the axis of the support plate 20 and the axis of the ring portion 10 are arranged in parallel.
