After the measuring ruler 8 is released, the spring sheet 7 allows the tape shaft 6 to rotate through elastic force, so that the tape shaft 6 can wrap around the measuring ruler 8 again. When the measuring ruler 8 is extended to fix the length of the measuring ruler 8, the adjusting block 9 is pushed so that the adjusting block 9 allows the second connecting plate 14 to drive the second extrusion wheel 15 at the slide plate 13 through the first connecting plate 12 to fix the extended length of the measuring ruler 8 under the cooperation of the first extrusion wheel 11, and then the fixing rod 16 is slidably fixed at the adjusting block 9, so that the second extrusion wheel 15 can keep the measuring ruler 8 The fixing effect avoids the measurement results being affected by shaking or other factors, improves the measurement stability, reduces the difficulty of users in measuring, facilitates users to measure, enables users to quickly measure, shortens the measurement time, and improves work efficiency. When the sealed door 5 is opened, the fixed shell 10 is exposed, and the moving block 19 is pressed to drive the clamping ring 21 to open through the traction plate 20. After the moving block 19 is released, the reset spring 18 resets the moving block 19 through elastic force, so that the moving block 19 drives the traction plate 20 to clamp the clamping ring 21 at the location to be fixed, ensuring that the starting point and the end point of the measurement do not change, ensuring the stability and accuracy of the measurement process, avoiding measurement errors caused by hand shaking or movement, and making the measurement results more accurate.
