[0024] In the specific implementation process, it is worth pointing out that, under the cooperation of the driving gear 17, the driven gear 18 and the driving rod 16, when measuring the cement column, the positioning rod 2 is pressed against one side of the cement column, and the driving gear 17 is driven to rotate by rotating the driving rod 16, so that the driven gear 18 drives the screw rod 8 to rotate, and the screw rod 8 is threadedly connected with the extension plate 5, driving the extension plate 5 to contract, so that the clamping rod 4 contacts the other side of the cement column, so as to read the scales 12 on the horizontal plate 1 and the extension plate 5 and add them together to obtain the diameter of the circular cement column;

[0025] Furthermore, the driving rod 16 extends to one end of the outer wall of the horizontal plate 1 and is fixedly connected to the turntable 9, and the outer wall of the turntable 9 is fixedly connected to the winding handle 19;
