Beneficial effects

[0006] 1. In this utility model, the first measuring tube is connected to a first side seat, which supports the first measuring tube from the side, preventing the bottom of the first measuring tube from directly contacting the ground and causing wear. A second side block is inserted into the first measuring tube, and a third side block is inserted into the second measuring tube, forming a three-section measuring ruler. This telescopic measuring ruler is convenient to carry and store. The third measuring tube has a third side seat, which is aligned with the side of the first side seat. During use, the first and third side seats work together to support the entire measuring ruler, preventing the bottom of the measuring ruler from touching the ground. Direct friction is used. Fixing base #1 is installed and fixed to the side of ruler tube #1. Ruler tube #2 is inserted into fixing base #1, which supports ruler tube #2, keeping it in the middle position. Fixing base #1 also prevents side block #2 from sliding out of ruler tube #1, preventing the ruler tubes from breaking apart. Fixing base #2 is installed and fixed on ruler tube #2. Ruler tube #3 is inserted into fixing base #2, which supports ruler tube #3 and keeps it centered. Fixing base #2 also prevents side block #3 from sliding out of ruler tube #2, preventing the ruler tubes from breaking apart and ensuring the entire measuring scale is securely in use.

[0007] 2. This utility model features a protractor plate fixed to the upper part of a ruler tube. A rotating protractor rod is connected to the protractor plate via a pivot, allowing the rod to rotate on the plate. The protractor plate has graduations, and rotating the rod facilitates the measurement of angles for road construction. A U-shaped fixing plate is attached to a sliding plate, which in turn mounts the sliding plate onto the ruler tube. The sliding plate can slide horizontally, and a set of protruding plates on the sliding plate prevents it from sliding out of the U-shaped fixing plate. The rotating protractor rod is inserted into the side groove of the plate, securing it and ensuring its position when stored. This integrated length and angle measurement function eliminates the need to carry multiple additional measuring tools. A single operation can collect the required length and angle data for road construction, reducing tool switching and carrying costs and accelerating the construction measurement process.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments: Example 1: A mobile measuring device for road construction includes a first ruler tube 01, a first side seat 02, a protractor 03, a rotating protractor 04, a sliding clamping plate 06, a clamping plate protrusion 08, a second ruler tube 10, a third ruler tube 12, a first fixed base 15, and a second fixed base 18. The first ruler tube 01 is connected to the first side seat 02 on its side, and the first side seat 02 supports the first ruler tube 01 on its side to prevent the bottom of the first ruler tube 01 from being directly exposed to the ground. Contact with the ground causes wear to the first ruler tube 01. The second ruler tube 10 has a second side block 11 on its side, which is adapted to the first ruler tube 01. The second side block 11 is inserted into the first ruler tube 01 and slides within it. The first fixing seat 15 has a first slot 16, which is adapted to the first ruler tube 01. The first ruler tube 01 is inserted into the first slot 16, and the first ruler tube 01 is connected to the first slot 16. The first fixing seat 15 is installed and fixed on the side of the first ruler tube 01. The first fixing seat 15 has a first locking hole 17. The second ruler tube 10 is adapted to the first locking hole 17. The second ruler tube 10 is inserted into the first locking hole 17 and slides within the first locking hole 17. The first fixing seat 15 supports the second ruler tube 10, so that the second ruler tube 10 is in the middle position of the first ruler tube 01. At the same time, the first fixing seat 15 prevents the second side block 11 from falling off the first ruler tube 01. The measuring ruler slides out of tube 01 to prevent the first measuring ruler tube 01 and the second measuring ruler tube 10 from breaking apart. The third measuring ruler tube 12 has a third side block 13 on its side. The third side block 13 is adapted to the second measuring ruler tube 10. The third side block 13 is inserted into the second measuring ruler tube 10 and slides inside the second measuring ruler tube 10, so that the first measuring ruler tube 01, the second measuring ruler tube 10 and the third measuring ruler tube 12 form a three-section measuring ruler. This telescopic measuring ruler is convenient to carry and store when in use.

[0016] Example 2: The second fixing base 18 of this utility model has a second slot 19, and a second ruler tube 10 is adapted to the second slot 19. The second ruler tube 10 is inserted into the second slot 19 and connected to the second slot 19. The second fixing base 18 is installed and fixed on the second ruler tube 10. The second fixing base 18 has a second locking hole 20, and a third ruler tube 12 is adapted to the second locking hole 20. The third ruler tube 12 is inserted into the second locking hole 20 and slides within the second locking hole 20. The second fixing base 18 supports the third ruler tube 12 and... The third ruler tube 12 is kept centered, while the second fixing seat 18 prevents the third side block 13 from sliding out of the second ruler tube 10, preventing the third ruler tube 12 from breaking off from the second ruler tube 10, ensuring the entire measuring ruler is securely in use. The third ruler tube 12 has a third side seat 14 on its side, which is aligned with the side of the first side seat 02. When in use, the first side seat 02 and the third side seat 14 work together to support the entire measuring ruler, preventing the bottom of the measuring ruler from directly rubbing against the ground.

[0017] Example 3: The protractor 03 of this utility model is connected to the first ruler tube 01. The protractor 03 is installed and fixed on the upper part of the first ruler tube 01. The lower surface of the rotating protractor 04 is in contact with the protractor 03. The rotating protractor 04 is connected to the protractor 03 through the rotating shaft 05, so that the rotating protractor 04 can rotate on the protractor 03. The protractor 03 has a scale. Rotating the protractor 04 makes it more convenient to measure the angle of road construction. The lower part of the U-shaped fixing plate 09 is connected to the first ruler tube 01. The sliding plate 06 is adapted to the U-shaped fixing plate 09. The sliding plate 06 is inserted into the U-shaped fixing plate 09 and slides inside the U-shaped fixing plate 09.

[0018] Example 4: The sliding plate 06 of this invention has a set of plate protrusions 08 on its side. A U-shaped fixing plate 09 fits into the plate protrusions 08. The sliding plate 06 has a plate side groove 07. A rotating protractor 04 is adapted to the plate side groove 07 and is inserted into the plate side groove 07. The U-shaped fixing plate 09 is fastened onto the sliding plate 06, and the sliding plate 06 is installed on the first ruler tube 01 by the U-shaped fixing plate 09. The sliding plate 06 can slide horizontally. The set of plate protrusions 08 on the sliding plate 06 prevents the sliding plate 06 from sliding out of the U-shaped fixing plate 09. The rotating protractor 04 is inserted into the plate side groove 07 to position the rotating protractor 04 and ensure its position when stored. It integrates length and angle measurement functions, eliminating the need to carry multiple additional measuring tools. A single operation can complete the collection of length and angle data required for road construction, reducing tool switching and carrying costs, and accelerating the construction measurement progress.

[0019] Example 5: The installation steps of this utility model are as follows: First, connect the protractor 03 to the first ruler tube 01.
