When the lifting motor 4763 is started and rotates forward to drive the lifting screw 4761 to rotate, because the lifting screw 4761 is hinged and fixed on the lifting seat plate 471, the ball nut 4765 on the lifting screw 4761 rises along with the lifting screw 4761 in the rotating process, and at the moment, the push block 4762 connected with the ball nut 4765 through the compression spring 4764 also rises together, and pushes the clamp seat plate 473 on the other side of the lifting seat plate 471 to slide upwards along the lifting slide rail 472. Similarly, after the measurement of the outer dimension of the tank is completed, the elevator motor 4763 rotates in the reverse direction, the elevator screw 4761 also rotates in the reverse direction, the ball nut 4765 descends, the push block 4762 also descends, and the clamp seat plate 473 also descends slowly along the elevator slide 472 under the pressure of its own weight.
