[0014] The utility model has the following beneficial effects:

[0015] 1. By setting up the clamping mechanism, when the gear rotates, the rack will also slide, and the rotating disc will slide in the T-shaped sliding slot along with the sliding of the rack. At this time, the rack will slide to the back side with the hinged block three, and the two hinged rods will be pushed. At this time, the hinged rod two will be pushed by the hinged rod, and since one end of the hinged rod two is limited by the rotating shaft two, the other end of the hinged rod two will be inclined, and the hinged rod three will also be pushed. At this time, the hinged rod three will also push the hinged rod one to one side, and the side of the hinged rod one is also limited by the rotating shaft one. When the two hinged rods three are pushed, the clamping rod will also be pushed. Because the hinged rod three, the hinged rod two, the hinged rod one, the rotating shaft two and the rotating shaft one form a parallelogram, when the hinged rod three moves to both sides with the clamping rod, it will move in a straight line and will not be inclined. Similarly, when the clamping rod needs to clamp the reinforcing steel bar, the handle can be reversed, and thus the end of the sliding rod is fixed. At this time, the hollow rod is pulled, and the scale on the sliding rod will change when the hollow rod is pulled. At this time, the clamping mechanism on the hollow rod is fixed on the reinforcing steel bar at the other end, and the scale displayed on the sliding rod at this time is the distance between the two reinforcing steel bars. The scale on the sliding rod is used to display the distance between the two reinforcing steel bars, and thus the measurement method is direct and intuitive, the influence of human factors on the measurement result is reduced, the numerical value of the reinforcing steel bar spacing can be obtained more accurately, and reliable data support is provided for the installation and quality control of reinforcing steel bars in building construction.

[0016] 2、By setting the anti-reverse mechanism, first one end of the slide bar is fixed, when fixed, first rotate the handle, then the worm will also rotate, at this time the worm gear will be rotated with the worm, at this time the rotating shaft three will rotate with the gear with the rotation of the worm gear, since the worm gear is not rotating with the worm, so the gear will rotate after rotating due to external force, so the worm gear and worm have anti-reverse effect, thereby achieving the effect of preventing the gear from rotating, so that the gear can be prevented from rotating due to accidental external force, such as vibration on the construction site, touching of personnel or objects, etc., so as to prevent unnecessary movement of the slide bar during measurement, thereby ensuring the stability and accuracy of measurement.
