Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1, refer to Appendix Figure 1-4 This utility model provides a measuring device for engineering cost measurement, including a support frame 1, a fixed base 2 installed at the bottom of the support frame 1, a motor 3 installed at the bottom of the inner cavity of the support frame 1, a threaded rod 4 installed at the output end of the motor 3, a threaded tube 5 threadedly connected to the surface of the threaded rod 4, the top of the threaded tube 5 penetrating the top of the support frame 1, an electric turntable 6 installed at the top of the threaded tube 5, a measuring instrument body 7 installed on both sides of the electric turntable 6 via brackets, a sliding groove 8 opened on the rear side of the threaded tube 5, a sliding block 9 slidably connected to the inner cavity of the sliding groove 8, and the rear side of the sliding block 9 fixed to the top of the rear side of the inner cavity of the support frame 1.

[0022] The usage process of this utility model is as follows: When using this utility model, if it is necessary to automatically adjust the height of the measuring instrument body 7, start the motor 3. The motor 3 drives the threaded tube 5 to move through the threaded rod 4. The threaded tube 5 drives the guide seat 11 and the sliding block 9 to slide in the inner cavity of the sliding groove 8 and the guide groove 10 respectively, which increases the stability of the threaded tube 5 when it moves and will not cause the threaded tube 5 to tilt or shake when it moves. The threaded tube 5 drives the measuring instrument body 7 to adjust its height through the electric turntable 6. The measuring instrument body 7 can be adjusted to a suitable usage height according to the needs, which also makes it easier to store and carry the measuring instrument body 7 later.

[0023] Example 2: The present invention provides a measuring device for engineering cost estimation, which differs from Example 1 in that:

[0024] Refer to the instruction manual appendix Figure 1-4 In this embodiment, a measuring device for engineering cost measurement is provided. A guide groove 10 is provided on the right side of the threaded tube 5. A guide seat 11 is slidably connected to the inner cavity of the guide groove 10. The right side of the guide seat 11 is fixed to the top of the right side of the inner cavity of the support frame 1. Mounting pins 12 are provided around the top of the fixed seat 2. The bottom of the mounting pins 12 penetrates the bottom of the fixed seat 2. Mounting holes that cooperate with the mounting pins 12 are provided around the top of the fixed seat 2. The bottom of the mounting holes extends to the bottom of the fixed seat 2. A maintenance plate 13 is installed on the bottom of the front of the support frame 1 by screws. The surface of the threaded rod 4 is provided with thread one. The inner cavity of the threaded tube 5 is provided with thread two that cooperates with thread one.

[0025] The specific implementation scenario is as follows: When using this utility model, if it is necessary to automatically adjust the height of the measuring instrument body 7, the motor 3 is started. The motor 3 drives the threaded tube 5 to move through the threaded rod 4. The threaded tube 5 drives the guide seat 11 and the sliding block 9 to slide in the inner cavity of the sliding groove 8 and the guide groove 10, respectively, which increases the stability of the threaded tube 5 during movement and prevents tilting or shaking. The threaded tube 5 drives the measuring instrument body 7 to adjust its height through the electric turntable 6. The measuring instrument body 7 can be adjusted to a suitable height according to needs, which also facilitates the later storage and carrying of the measuring instrument body 7. The measuring instrument body 7 is fixed on top of the electric turntable 6, which is a device that achieves rotation through electric drive. The core working principle of the measuring instrument is based on the linkage of motor power transmission and mechanical structure. The electric turntable 6 can drive the measuring instrument body 7 to be adjusted at multiple angles through the brackets on both sides above, which facilitates the operation of the measuring instrument body 7. In the engineering measuring instrument body 7, the main task of signal processing is to accurately acquire, convert and process the measurement signal. Acquisition usually uses a high-sensitivity sensor to convert physical quantities into electrical signals for reading. Then, analog-to-digital conversion is performed to convert analog signals into digital signals. Finally, digital signal processing technology is used to perform filtering, gain, demodulation and other processing operations to improve measurement accuracy and reliability. The measuring instrument body 7 is existing technology and will not be described in detail here. The contents not described in detail in this description are existing technologies known to those skilled in the art.
