[0020] When this embodiment is used, the worker extends the cone rod 6 from the bottom of the telescopic frame 1 and inserts it into the ground for fixation, and then adjusts the height of the support ring 4 to allow multiple support rods 3 to abut against the ground. If the device is in a tilted state after fixation, the worker adjusts the angle of the laser rangefinder 15 by adjusting the component to make the laser rangefinder 15 in a horizontal state, thereby improving the detection effect and quality of the laser rangefinder 15.

[0021] Embodiment 2

[0022] like Figure 2 and Figure 3 As shown, a positioning and ranging device proposed in this embodiment, compared with the first embodiment, in this embodiment, the adjustment component includes a rotating frame 11 rotatably set on the fixed plate 8, a nut 12 threadedly connected to the rotating frame 11, two abutment blocks 13 slidably set on the fixed plate 8, and two springs 14 set on the fixed plate 8, the two springs 14 are respectively located between the two abutment blocks 13 and the fixed plate 8, and the laser rangefinder 15 is located at the top of the rotating frame 11. The fixed plate 8 has an angle meter, and the rotating frame 11 has a pointer, and the angle meter and the pointer are in the same direction.

[0023] When this embodiment is in use, the worker loosens the nut 12 so that the nut 12 does not abut against the fixed plate 8, then pushes the top of the rotating frame 11 by hand to rotate it to be flush with the horizontal plane, and then turns the nut 12 to stop the rotating frame 11 from moving. The abutment blocks 13 abut against it from both sides of the rotating frame 11, thereby preventing the rotating frame 11 from rotating toward both sides when the device is placed vertically. The worker adjusts the angle of the rotating frame 11 in real time through the angle meter and the pointer to record the detection process.
