[0007] Based on the above structure, the unfolding spring drives the telescopic plate to slide vertically along the inner wall of the handle through its own elastic force, and the sliding of the telescopic plate drives the two groups of support rods to move synchronously, so that the sliding of the telescopic plate drives the main bracket and the connecting frame to rotate relative to each other through the support rod. At the same time, the movement of the support rod drives the sub-bracket at one end of the connecting column to rotate relative to the main bracket through the connecting rod, so that the first scale on the outer wall of the connecting frame, the main scale on the outer wall of the main bracket, and the sub-scale on the outer wall of the sub-bracket are located on the same straight line, thereby realizing the unfolding operation of the first scale, the main scale and the sub-scale, and facilitating the folding and storage operation of the measuring ruler.

The positioning block 506 is driven to be embedded in the positioning frame 5 of the outer wall of the main bracket 3 to realize the positioning operation of the main bracket 3 and the auxiliary bracket 4. After the measurement is completed, the staff presses the pressure rod 503. The movement of the pressure rod 503 overcomes the elastic force of the reset spring 501 and drives the lifting block 502 to slide vertically.

When working, the fixed spring 601 drives the connecting plate 602 to slide through its own elastic force. The sliding of the connecting plate 602 drives the connecting grooves 605 on the outer walls of the two sets of sliding plates 604 to move synchronously. The sliding of the connecting grooves 605 drives the fixed card block 607 to slide through the telescopic rod 606. The fixed card block 607 slides and engages with the outer wall of the fixed block 608, thereby realizing the fixing operation of the telescopic plate 202 on the outer wall of the fixed block 608, avoiding accidental touching of the telescopic plate 202, which causes the main bracket 3 and the auxiliary bracket 4 to unfold when not working.

When working, by setting the inclined connecting groove 605, it is conducive to the sliding of the connecting groove 605 through the telescopic rod 606 to drive the fixed block 607 to slide, thereby realizing the sliding operation of the fixed block 607.

[0048] For further information, see Fig.13 and Fig.14 The shape of the fixed block 608 is an isosceles trapezoid, and the shape of the fixed clamping block 607 is a trapezoid. The telescopic plate 202 forms a locking structure with the fixed frame 6 through the fixed clamping block 607 and the fixed block 608. When working, the fixed clamping block 607 slides and engages with the outer wall of the fixed block 608 to achieve the fixing operation of the telescopic plate 202 on the outer wall of the fixed block 608, thereby avoiding accidental touching of the telescopic plate 202, which causes the main bracket 3 and the auxiliary bracket 4 to be unfolded when not working.

[0049] The working principle of the present invention is: when the measuring device for architectural engineering design is used, first, the unfolding spring 201 drives the telescopic plate 202 to slide vertically along the inner wall of the handle 2 through its own elastic force, and the sliding of the telescopic plate 202 drives the two groups of support rods 203 to move synchronously, so that the telescopic plate 202 slides through the support rods 203 to drive the main bracket 3 and the connecting frame 1 to rotate relative to each other. At the same time, the movement of the support rods 203 drives the auxiliary bracket 4 at one end of the connecting column 204 to rotate relative to the main bracket 3 through the connecting rod 205, so that the first scale 101 on the outer wall of the connecting frame 1, the main scale 301 on the outer wall of the main bracket 3, and the auxiliary scale 401 on the outer wall of the auxiliary bracket 4 are located on the same straight line, thereby realizing the unfolding operation of the first scale 101, the main scale 301 and the auxiliary scale 401, which is convenient for the folding and storage operation of the measuring ruler.

[0051] Next, the staff measures the length of the building object using the first scale 101 , the main scale 301 and the auxiliary scale 401 .

[0052] Then, after the measurement is completed, the staff presses the pressure rod 503, and the movement of the pressure rod 503 overcomes the elastic force of the reset spring 501 and drives the lifting block 502 to slide vertically. The sliding of the lifting block 502 drives the pressure block 504 to fit with the positioning block 506. By setting the connecting surface of the pressure block 504 and the positioning block 506 to be inclined, it is beneficial for the pressure block 504 to move and drive the positioning block 506 to overcome the positioning spring 505 and retract into the connecting column 204, so as to facilitate the folding of the main bracket 3 and the auxiliary bracket 4.

[0053] Finally, the staff pushes the pull block 609, and the movement of the pull block 609 drives the telescopic plate 202 to overcome the elastic force of the expansion spring 201 and slide in the opposite direction along the inner wall of the handle 2 through the fixed block 608. When the fixed block 608 slides to the inside of the fixed frame 6, the fixed spring 601 drives the connecting plate 602 to slide through its own elastic force, and the sliding of the connecting plate 602 drives the connecting grooves 605 on the outer walls of the two sets of sliding plates 604 to move synchronously. By setting an inclined connecting groove 605, it is beneficial for the connecting groove 605 to slide through the telescopic rod 606 to drive the fixed card block 607 to slide. The fixed card block 607 slides and engages with the outer wall of the fixed block 608, thereby realizing the fixing operation of the telescopic plate 202 on the outer wall of the fixed block 608, avoiding accidental touching of the telescopic plate 202, which causes the main bracket 3 and the auxiliary bracket 4 to unfold when not working.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
