When the existing expansion tester for the Leeb clamp is used, the Leeb clamp is placed at the top of a cushion block before measurement, then the Leeb clamp is measured by using a scale at the top, after the preparation of a Leeb clamp test piece is completed, the Leeb clamp is hung on a rotation line, then the left scale is used for measuring the Leeb clamp test piece, and then the volume safety of cement is calculated and checked through two sets of measurement results, so that the measurement is completed.

The expansion tester for the traditional Leeb clamp has certain defects in detection, the pointer distance of the initial state needs to be measured before the Leeb clamp is hung heavily, and due to the fact that the spiral line or the rubber band is adopted for hanging the weight, under the condition of long-time use, the Leeb clamp cannot be calibrated at the initial position due to various factors of ageing and elastic relaxation of the spiral line or the rubber band, and then the final result has large errors. In view of this, we propose an expansion tester for adjustable leigh clamps.
