[0022] Please refer to the attached Figure 1-4 A level ruler comprises a ruler body 1, a first level bubble 2, a second level bubble 3, a third level bubble 4, a hinge 101, a depression measuring mechanism, a fixing mechanism and a protection mechanism, wherein the first level bubble 2, the second level bubble 3 and the third level bubble 4 are all arranged on the ruler body 1, the second level bubble 3 is located in the middle of the ruler body 1, the first level bubble 2 and the third level bubble 4 are arranged on both sides of the ruler body 1, the hinge 101 is arranged on the ruler body 1 near the first level bubble 2, the depression measuring mechanism is arranged on the hinge 101, the fixing mechanism is arranged between the depression measuring mechanism and the ruler body 1, and the protection mechanism is arranged on the outer side of the ruler body 1;

[0023] The depression measuring mechanism includes a horizontal L-shaped support block 5, a dial 6, a slider 7, a measuring rod 8 and a recording rod 9. The horizontal L-shaped support block 5 is arranged on the hinge 101, the dial 6 is arranged on the horizontal L-shaped support block 5, the slider 7 is slidably arranged on the horizontal L-shaped support block 5, the measuring rod 8 is arranged on the slider 7, the recording rod 9 is arranged on the measuring rod 8, and the end of the recording rod 9 is in contact with the dial 6.

When it is necessary to measure the ground, the slider 7 and the measuring rod 8 can be moved. The measuring rod 8 will synchronously drive the recording rod 9 to move downward along the dial 6. The distance that the recording rod 9 moves on the dial 6 is equal to the distance from the measuring rod 8 to the deepest part of the depression.

When the ruler body 1 needs to be used, the protective cover 14 can be flipped upward to open.

[0029] In some embodiments, an anti-collision pad is provided at the bottom of the ruler body 1.

[0030] By adopting the above technical solution, the provision of the anti-collision pad can prevent the ruler body 1 from collision.

[0031] In some embodiments, the bottom end of the measuring rod 8 is tapered.
