s1, pressing the trapezoidal block (102) on the first tape body (1) to enable the trapezoidal block to be inserted into the ground gap or the wall gap, and fixing the position of the first tape body (1);
s2, pulling the second tape measure body (11) to be far away from the first tape measure body (1) until the position to be measured is reached, pressing the trapezoidal blocks (102) on the second tape measure body (11) to be inserted into the ground gap or the wall gap, and fixing the position of the second tape measure body (11);
s3, when the scale (3) needs to be fixed to prevent the scale from being rewound, the connecting rod (71) slides downwards, so that the connecting rod (71) drives the contact block (73) to slide downwards along the contact plate (74), the contact block can abut against the scale (3) to form dislocation, the scale (3) is clamped in the first scale body (1) and cannot be rewound, and reading can be recorded;
s4, in order to conveniently get the whole reading, the rotating rod (43) slides in the first tape body (1), the clamping groove (42) arranged on the rotating rod (43) is clamped on the first roller (41), so that the first coil spring (51) in the first tape body (1) can be adjusted by rotating the rotating rod (43), the first coil spring (51) in the first tape body (1) is tightened, the fixing mechanism (7) is loosened, the scale (3) can be rewound into the tightened first tape body (1), and the whole reading is conveniently taken;
s5, in order to facilitate adjustment, a second rotating shaft (49) is further arranged in the first tape body (1), a second coil spring (52) is mounted on the second rotating shaft (49), the second coil spring (52) is further connected with a second roller (48) mounted on the rotating rod (43), before adjustment is needed, the rotating rod (43) can be rotated in advance and slides towards the first tape body (1), and the rotating rod (43) can be rotated when the second coil spring (52) is rewound, so that automatic adjustment is completed;
s6, when multi-direction measurement is needed to be carried out by using one datum point, the first tape body (1) is fixed on the datum point, and after one direction measurement is finished, the trapezoidal block (102) slides to the top of the second tape body (11), so that the direction of the second tape body (11) is changed by using the first tape body (1) as the datum point, and the measurement is convenient.
