However, when measuring the depth of a hole, if there are foreign objects inside the hole, the measuring tape cannot fit tightly against the bottom of the hole, resulting in inaccurate measurements. Therefore, to address these issues, an auxiliary measuring tape for construction engineering cost estimation is proposed. Utility Model Content

[0022] Example

[0023] like Figure 1-3 As shown, an auxiliary measuring ruler for construction engineering cost estimation includes a connecting plate 9 and a first measuring rod 6. The first measuring rod 6 is movably disposed on the inner side of the connecting plate 9. The first measuring rod 6 can slide along the connecting plate 9 and can also rotate on the inner side of the connecting plate 9. A first scale line 7 is provided on the outer side of the first measuring rod 6. A rotating mechanism is provided at the top of the first measuring rod 6, and a cleaning mechanism is provided on the outer side of the bottom of the first measuring rod 6. Support mechanisms are provided around the connecting plate 9. The depth of the hole can be measured by the first measuring rod 6 and the first scale line 7.

[0024] As a further improvement to this utility model, such as Figure 1 As shown, the cleaning mechanism includes bristles 8 fixed to the outer side of the bottom of the first measuring rod 6, and the bristles 8 are made of nylon. The first measuring rod 6 carries the bristles 8 to rotate rapidly at the bottom of the hole. The bristles 8 sweep the foreign objects at the bottom of the hole to the bottom periphery of the first measuring rod 6, so that the bottom end face of the first measuring rod 6 can directly contact the bottom of the hole, thereby improving the accuracy of hole depth measurement.

[0025] As a further improvement to this utility model, such as Figure 1 and Figure 3 As shown, the rotating mechanism includes a motor 3 fixedly connected to the first measuring rod 6 via a rotating shaft. A protective shell 2 is fixedly connected to the outside of the motor 3. A storage battery 1 is fixedly connected to the top of the protective shell 2. A guide assembly is fixedly connected to one end of the protective shell 2. The storage battery 1 can supply power to the motor 3, and the motor 3 can rotate quickly together with the first measuring rod 6 and the brush bristles 8.

[0026] As a further improvement to this utility model, such as Figure 1 As shown, the guide assembly includes a fixed plate 4 fixedly connected to the protective shell 2. A guide shaft 5 is fixedly connected to the bottom end of the fixed plate 4. The guide shaft 5 is slidably connected to the connecting plate 9. The normal movement of the protective shell 2 and the motor 3 can be ensured by the guide shaft 5.

[0027] As a further improvement to this utility model, such as Figure 1 and Figure 2 As shown, the support mechanism includes a guide shell 10 fixedly connected to the connecting plate 9. A spring 11 is fixedly connected to the inner side of the guide shell 10. A second measuring rod 12 is slidably connected to the other end of the spring 11. A top block 14 is fixedly connected to the other end of the second measuring rod 12. A second scale line 13 is provided at the top of the second measuring rod 12. Since the width of the top block 14, the length of the guide shell 10, and the diameter of the connecting plate 9 are fixed, the diameter of the hole is the sum of the widths of two top blocks 14, the lengths of two guide shells 10, the diameter of the connecting plate 9, and the diameters of two second measuring rods. When measuring the diameter of a hole, first retract the second measuring rod 12, along with the top block 14, towards the vertical center line of the connecting plate 9. Then, insert the top block 14 into the inside of the hole. Next, release the second measuring rod 12. At this point, under the elastic force of the spring 11, the second measuring rod 12, along with the top block 14, will fit against the inner wall of the hole. Then, the scale line on the second measuring rod 12 can be read. Then, multiply the sum of the width of the top block 14, the length of the guide shell 10, the diameter of the connecting plate 9, and the scale value measured by the second measuring rod 12 by two to get the diameter of the hole.

[0028] As a further improvement to this utility model, such as Figure 1 and Figure 2 As shown, a lever 15 is fixedly connected to the top of the second measuring rod 12, and the length of the second measuring rod 12 and the top block 14 can be adjusted by lever 15.

[0029] Workflow: When measuring the depth and diameter of a hole, first retract the second measuring rod 12, along with the top block 14, towards the vertical center line of the connecting plate 9. Then, insert the top block 14 into the hole. At this time, the first measuring rod 6 will also extend into the hole. Next, release the second measuring rod 12. Under the elastic force of the spring 11, the second measuring rod 12, along with the top block 14, will fit against the inner wall of the hole. Then, the scale line on the second measuring rod 12 can be read. Then, multiply the sum of the width of the top block 14, the length of the guide shell 10, the diameter of the connecting plate 9, and the scale value measured by the second measuring rod 12 by two to get the diameter of the hole. At the same time, make the motor 3 rotate the first measuring rod 6 and the brush 8 together quickly. The brush 8 sweeps the foreign objects at the bottom of the hole to the bottom of the first measuring rod 6, so that the bottom surface of the first measuring rod 6 can directly contact the bottom of the hole, thereby improving the accuracy of the hole depth measurement. The scale line 7 shows the depth of the hole.
