[0044] The implementation principle of the device for measuring the flatness of the joint surface of an aluminum profile in the embodiment of the present application is as follows: Before measurement, first, the first positioning rod 7 is passed through the first positioning groove 21 on the side close to the support block 2, and the abutment plate 6 is positioned at the top, so that the first telescopic rod 41 is in the shortest state, and the first spring 42 is in a compressed state, and the first positioning rod 7 is passed through the first positioning groove 21, and the first positioning rod 7 is rotated to drive the first limiting block 71 to be clamped in the first limiting groove 63, so as to limit the abutment plate 6 to the highest position; then the operating rod 101 is rotated to drive the second limiting block 102 to rotate into the second limiting groove 27, and the moving operating rod 101 drives the second limiting block 102 to align with the second limiting groove 28, and the rotating operating rod 101 drives the second limiting block 102 to be clamped in the second limiting groove 28, so that the end face of the second positioning rod 8 away from one end of the connecting rod 10 is located at the intersection of the first mounting groove 22 and the second limiting groove 28. At the boundary between the two positioning holes 24, at the same time, the end face of the third positioning rod 9 away from the end of the connecting rod 10 is located at the boundary between the second mounting groove 23 and the third positioning hole 25; then the support block 2 is moved to the position to be measured, so that the table top or aluminum profile is located between the abutment plate 6 and the second support block 2, the first positioning rod 7 is rotated to drive the first limit block 71 to move into the first limit groove 62, and the first positioning rod 7 is pulled in the direction away from the support block 2 to disengage the first positioning rod 7 from the first positioning groove 21, and then the abutment plate 6 is released, so that the abutment plate 6 is abutted against the top of the table top or aluminum profile under the action of the first telescopic rod 41 and the first spring 42, and the bottom of the table top or aluminum profile is abutted against the second support plate 5, so that the support block 2 can be positioned at the corresponding position, and then the measuring component 1 is positioned at the corresponding position.

[0045] During measurement, the position and height of the measuring rod 14 assembly are adjusted by rotating the mounting block 31 and extending the second telescopic rod 32, so that the reference seat 11 is placed on one side of the joint to be measured, and the measuring rod 14 is aligned with the other side of the joint. The height difference can be transmitted to the dial 12 through the measuring rod 14, and the height difference of the joint can be observed by observing the dial 12.

[0046] When no work is needed, first, the first positioning rod 7 is passed through the first positioning groove 21 on the side close to the supporting block 2, and the abutment plate 6 is positioned at the top, so that the first telescopic rod 41 is in the shortest state, and the first spring 42 is in a compressed state, and the first positioning rod 7 is passed through the first positioning groove 21, and the first positioning rod 7 is rotated to drive the first limiting block 71 to be clamped in the first limiting clamping groove 63, thereby limiting the abutment plate 6 to prevent it from shaking; then, the mounting block 31 is moved to the bottom of the second mounting groove 23, and is rotated until the third positioning groove 311 is aligned with the third positioning rod 9, and the operating rod 101 is rotated to drive the third positioning groove 311 to be aligned with the third positioning rod 9. The second limit block 102 rotates to the second limit groove 27, and the moving operating rod 101 drives the second limit block 102 to align with the third limit slot 29, and at the same time drives the connecting rod 10 to move in the direction close to the mounting block 31, drives the third positioning rod 9 to enter the third positioning groove 311, and the second positioning rod 8 also enters the second positioning groove 321; the rotating operating rod 101 drives the second limit block 102 to be clamped in the third limit slot 29, so that the second positioning rod 8 and the third positioning rod 9 cannot move, so that the mounting block 31 can be limited, and then the measuring component 1 can be limited, so that the device as a whole is stable and firm.

[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
