The bottom of fixes sleeve 251 is opening end；Three support bars are uniformly along the circumferential direction hinged with vertically on the outer wall of fixed column 21
26, the middle part of every support bar 26 is hinged by the outer wall of fixes sleeve 251 of connecting rod 27 and relative rangefinder fixed seat 25,
A fixed plate 28 is hinged with the every bottom of support bar 26, fixed plate 28 can be L-type, convenient to fix in blasthole aperture,
Be equipped with anti-skid wearable layer 29 in the outside of every piece of fixed plate 28, anti-skid wearable layer 29 can increase fixed plate 28 and blasthole hole wall it
Between frictional force, the stability of enhancing ranging fixed mount 2；Adjusted by adjusting the length of expansion link 24 connecting rod 27 with it is corresponding
Angle between support bar 26, and then the distance between three fixed plates 28 are adjusted, to make ranging fixed mount 2 to be fastened in difference
In the blasthole in aperture, and then improve the applicability of blast hole depth detection means described in the utility model；Rangefinder fixed seat 25
Including fixes sleeve 251, observation panel 252 is provided with the outer wall of fixes sleeve 251, Laser Measuring can be observed by observation panel 252
Setting height(from bottom) of the distance meter 1 in fixes sleeve 251；Activity is placed respectively on the side wall of fixes sleeve 251 of the both sides of observation panel 252
There is a screw rod 253, be bolted with a locking nut 254 respectively on the every screw rod 253 outside fixes sleeve 251, solid
