By adjusting the height of the supporting legs 110 on the mounting plate 100, the mounting plate 100 is leveled and perpendicular to the axial direction of the blast hole 701 to be measured, so as to facilitate the depth measurement of the blast hole 701.

[0035] The fixing member is arranged to fix the supporting legs 110 after the adjustment of the positions of the supporting legs 110 on the mounting plate 100, so as to ensure that the supporting legs 110 do not slide on the mounting plate 100 during the measurement, and affect the leveling of the mounting plate 100 and the measurement.

[0036] In combination with Figures 1-6 As shown, in the embodiment, the mounting plate 100 is provided with through holes at the positions of the four corners for the corresponding supporting legs 110 to pass through. The fixing member includes a connecting cylinder fixedly connected to the through hole and sleeved on the supporting leg 110. The upper end surface of the connecting cylinder is provided with a circular truncated cone portion 410. The lower end portion of the connecting cylinder is provided with a threaded portion 412. The circular truncated cone portion 410 is provided with a plurality of notch portions 411 along the circumferential direction thereof. A driving cylinder 400 is threadedly connected to the outside of the supporting leg 110. The driving cylinder 400 is provided with an inclined surface matched with the circular truncated cone portion 410. The driving cylinder 400 is threadedly connected to the threaded portion 412 to drive the inclined surface to press the circular truncated cone portion 410, so that the circular truncated cone portion 410 tightly holds the supporting leg 110.

[0038] Specifically, when the driving cylinder 400 is threadedly connected to the connecting cylinder, the inclined surface can press the circular truncated cone portion 410 to move close to each other, and the notch portion 411 is matched to be reduced. Finally, the circular truncated cone portion 410 tightly holds the supporting leg 110, so that the mounting plate 100 is fixed on the supporting leg 110.

[0039] In this embodiment, in order to facilitate the leveling of the mounting plate 100, the upper plate surface of the mounting plate 100 is provided with a plurality of bubble levels 101, and the bubble levels 101 are observed to determine whether the mounting plate 100 is in a horizontal state. When any side of the mounting plate 100 is not horizontal, any leg 110 can be adjusted individually until the mounting plate 100 is kept horizontal.
