The handle 3 and the steel bar 4 are connected by a rivet 301. The handle 3 extends the working range of the measuring ruler 1 and indirectly improves the working ability of the personnel.

[0023] An observation hole 103 is arranged inside the measuring ruler 1. The slideway 104 extends from the bottom end of the measuring ruler 1 to the top end of the measuring ruler 1. One end of the rotating shaft 106 is connected to the measuring ruler 1, and the other end of the rotating shaft 106 is connected to the guide plate 105.

[0024] The rotating shaft 106 drives the measuring ruler 1 to rotate, and the special-shaped surface 102 fits the special-shaped reference of the component to be measured, enabling the measuring ruler 1 to fit on the surface of the component to be measured. This avoids the problem of repeatedly adjusting the position of the measuring ruler 1 during positioning, improves the ability to measure in a narrow space, and thus improves the measurement accuracy and efficiency. When using the measuring ruler 1, the handle 3 and the steel bar 4 can be rotated by a certain angle through the rotating cylinder 5, which is convenient for personnel to observe the reading and visually inspect. At the same time, the special-shaped surface 102 fits the special-shaped reference, achieving accurate positioning and further ensuring the accuracy of observing the reading and visual inspection.

[0025] One end of the guide plate 105 is provided with a limit block 107. The limit block 107 is connected to the guide plate 105.

The personnel can twist the tightening bolt 6 through the auxiliary plate 602 until the rubber pad 601 contacts the measuring ruler 1, fixing the position of the positioning assembly 2, thereby realizing the functions of measuring the spacing and thickness, effectively improving the defects of the measuring ruler 1 and the right-angle ruler during measurement, and further improving the efficiency and accuracy of the measurement operation.

[0028] Working principle: When a person needs to measure dimensions in a narrow space, first attach the special-shaped surface 102 to the special-shaped reference of the part to be measured. The rotating shaft 106 drives the measuring ruler 1 to rotate, so that the measuring ruler 1 can be attached to the surface of the part to be measured, and accurate dimension data can be obtained. When a person needs to measure thickness or spacing, after installing the positioning component 2 on the measuring ruler 1, the person manipulates the handle 3 to move, so that the positioning component 2 slides on the measuring ruler 1, thereby realizing the measurement of thickness or spacing. The person inserts the limit pin 303 into the inside of the limit hole 1071 to fix the position of the measuring ruler 1. At this time, the measuring ruler 1 and the steel bar 4 can form a right-angle ruler, realizing the conversion between the ruler and the right-angle ruler and improving the functionality.
