The other end of the pull rope 9 extends out of the housing 5 after passing around the bottom of the second guide roller 8. A slot 10 is provided at the bottom of the side wall of the housing 5 for the pull rope 9 to pass through. An observation port 11 is provided in the housing 5 corresponding to the position of the first guide roller 7. A pull rod 12 is provided between the two connecting plates 3. A connecting rod 13 is fixed to one end of the pull rod 12. A second measuring rod 14 is fixed to the bottom end of the connecting rod 13. The second measuring rod 14 is slidably connected to the first measuring rod 2. The bottom surface of the second measuring rod 14 is in contact with the top surface of the first measuring rod 2. When the second measuring rod 14 is in contact with the first measuring rod 2, the 0 position of the tape measure 6 is displayed through the observation port 11.

[0022] The connecting rod 13 is slidably fitted with a first guide cylinder 15 and a second guide cylinder 16. One side of the first guide cylinder 15 and the second guide cylinder 16 are fixedly connected to the side wall of the main body of the vertical rod 1. A limiting ring 17 is fixedly fitted on the connecting rod 13. A spring 18 is fixedly provided between the top end of the limiting ring 17 and the bottom end of the first guide cylinder 15. The spring 18 is fitted on the connecting rod 13. The bottom end of the limiting ring 17 is in contact with the top end of the second guide cylinder 16.

[0028] Working principle;

[0029] In use, in its initial state, under the action of spring 18, the second measuring rod 14 is in contact with the first measuring rod 2, and the 0 position of the tape measure 6 is displayed through the observation port 11. During measurement, the operator adjusts and locks the lengths of the vertical rod 1 and the connecting rod 13 according to their height and measurement needs. Then, the device is inserted into the double-layer steel mesh through the steel mesh grid using the handle 4, so that the first measuring rod 2 abuts against the lower layer of steel mesh. Next, the pull rod 12 is pulled, which drives the connecting rod 13 and the second measuring rod 14 upward, so that the second measuring rod 14 abuts against the upper layer of steel mesh. During this process, the connecting rod 13 pulls the tape measure 6 synchronously through the pull rope 9. The operator reads the data displayed on the tape through the observation port 11 on the cover. This data, plus the sum of the thicknesses of the second measuring rod 14 and the first measuring rod 2, gives the spacing of the double-layer steel mesh. After the measurement is completed, release the finger that pulled the lever 12. Under the action of the spring 18, the second measuring rod 14 returns to its original position and fits against the first measuring rod 2. The tape measure 6 also automatically returns to its original position under the action of the spring in the winding drum.

[0030] During nighttime measurements, turning on the lighting 20 illuminates the direction of the second measuring rod reset 14 and the first measuring rod 2, facilitating the insertion of the device into the double-layer steel mesh through the steel mesh grid.
