Detailed description of the invention
Fig. 1 is the structural diagram of the present invention.
Fig. 2 is the structural schematic diagram that Laser emission cylinder of the invention is matched with sleeve.
Specific embodiment
With reference to the accompanying drawing and specific embodiment the invention will be further described, in the illustrative examples of the invention
And explanation is used to explain the present invention, but not as a limitation of the invention.
As shown in Figure 1 and Figure 2, a kind of hand-held blast hole depth measuring device of the present embodiment, including laser range finder 1, institute
1 front end of laser range finder is stated equipped with Laser emission cylinder 3, the 3 front end outer cover of Laser emission cylinder is equipped with same with Laser emission cylinder
The sleeve of the heart, the sleeve are evenly divided into three pieces of arc panels 4 along axial direction, and the outer wall vertical of 3 front end of Laser emission cylinder is solid
Surely there are three groups of uniformly distributed screw rod groups in a ring, every group of screw rod group includes at least two along the axial distribution of Laser emission cylinder 3 and mutually
Parallel screw rod 10, the axial centre of every piece of arc panel 4 offer through-hole 41 corresponding with screw rod 10, and the end of screw rod 10 is passed through
Locking nut 7 is equipped on the screw rod 10 outside arc panel 4 after wearing the through-hole 41 on arc panel 4, the front end of arc panel 4 will be more than
3 front end a distance of Laser emission cylinder is used to protrude into 4 front end of arc panel in blasthole mouth, and the screw rod 10 is equipped with graduation mark 9,
Spring 6 is arranged on screw rod 10 between 3 outer wall of Laser emission cylinder and 4 inner wall of arc panel, and 6 one end of spring is fixed on
Laser emission drum outer wall, the other end are free end, and the quantity of the screw rod 10 in the present embodiment in every group of screw rod group is two, because
