However, when used in the machinery industry, the vibration of the machine may cause the data cable and the data acquisition interface to become loose, resulting in poor contact between the data cable and the data acquisition interface, causing unstable data transmission. In more serious cases, the data cable is detached from the data acquisition interface, making it impossible to transmit the data collected by the smart sensor and unable to be used normally.

[0024] As a technical optimization solution of the utility model, the outer surface of the sliding sleeve 10 is fixedly connected to the guide rail 11, the inner side of the sleeve 9 is provided with a sliding groove 16, the inner wall of the sliding groove 16 is slidingly connected to the outer surface of the guide rail 11, and a spring 12 is arranged inside the sleeve 9.

[0025] In this embodiment, the slide groove 16 can guide the sliding direction of the guide rail 11, and the guide rail 11 limits the rotation of the slide sleeve 10, so that the slide sleeve 10 has only the function of sliding up and down.

[0026] As a technical optimization solution of the present invention, one end of the spring 12 is fixedly connected to the inner bottom wall of the sleeve 9, and the other end of the spring 12 is fixedly connected to one end of the sliding sleeve 10 located inside the sleeve 9.

[0027] In this embodiment: after the sliding sleeve 10 slides toward the inside of the sleeve 9, the sliding sleeve 10 is pushed to slide toward the outside of the sleeve 9 by the spring 12, so that the sliding sleeve 10 has a reset function.

[0028] As a technical optimization solution of the utility model, one end of the sliding sleeve 10 located outside the sleeve 9 is fixedly connected to a first chuck 13, the outer surface of the first chuck 13 is in sliding contact with a second chuck 14, and the inner wall of the second chuck 14 is fixedly connected to the outer surface of the forward and reverse screw rods 2.

The teeth on the first chuck 13 and the second chuck 14 have an inclined angle, which is convenient for the second chuck 14 to push the first chuck 13 to move backward while rotating. The sleeve 10 is elastically supported by the spring 12, so that the first chuck 13 is tightly in contact with the second chuck 14, which can prevent the forward and reverse screw rods 2 from rotating due to vibration.

[0034] Working principle: first, dock the data line with the data acquisition interface body 6, and then rotate the forward and reverse screw rods 2 to drive the support plate 3 to shrink inward through the rotation of the forward and reverse screw rods 2. While the support plate 3 shrinks, the pressure plate 4 is driven to move its position through the guide rod 7. After the pressure plate 4 contacts the data line, the pressure plate 4 pushes the spring 2 8 to shrink. After the spring 2 8 shrinks to a suitable position, the data line is fixed and the rotation of the forward and reverse screw rods 2 is stopped. While the forward and reverse screw rods 2 rotate, the second chuck 14 can be driven to rotate. After the second chuck 14 rotates, the first chuck 13 can be pushed to move backward, and then the first chuck 13 pushes the sleeve 10 to slide into the inside of the sleeve 9. After the sleeve 10 slides into the inside of the sleeve 9, the sleeve 10 compresses the spring 12 and enters the lowest point after the first chuck 13 and the second chuck 14 are misaligned. The sleeve 10 is pushed to slide to the outside of the sleeve 9 by the spring 12, and at the same time, the sleeve 10 pushes the first chuck 13 to make tight contact with the second chuck 14.
