In the prior art, a field measurer needs to hold the laser range finder to reach one wall and then aim at the other wall to measure, but the field measurer can not approach the two walls and the level of the laser range finder can not be guaranteed in actual measurement, so that the measurement result is inaccurate. Adopt this embodiment laser range finder support location laser range finder 400 when carrying out distance measurement, for example carry out horizontal distance measurement between two parallel walls: after the laser range finder 400 is positioned in place on the laser range finder clamping seat 340, the laser range finder support is erected at any position between two walls, the second pointer 330 is adjusted to be located at the zero (0) scale of the angle scale 321 on the vertical indicating disc 320, the first pointer 230 is rotated to enable the laser range finder 400 to be aligned with the first wall surface to measure the first reading, then the first pointer 230 is rotated by 180 degrees to be aligned with the second wall surface to measure the second reading, and the first reading and the second reading are added to obtain the horizontal distance between the two walls. For the case of unknown wall orientation, the two readings are specifically read by pointing the second pointer 330 to the zero (0) scale of the angle scale 321, then making the laser beam of the laser range finder 400 approximately perpendicular to the wall surface by adjusting the first pointer 230, and then rotating the first pointer 230 in one direction in the direction of decreasing the reading of the laser range finder 400, wherein when the reading is just decreased to increased, the measurement value before the increase is the horizontal distance from the wall surface; for the horizontal distance measurement of the wall surface with the known direction, that is, if the direction angle of the wall surface to be measured is known, if the direction angle of the inner normal of the first wall surface is 60 degrees north and east, after the laser range finder support is well arranged, the second pointer 330 points to the zero (0) scale of the angle scale 321, the first pointer 230 is adjusted to the 60 degrees, and the measured distance is the horizontal distance from the laser range finder 400 to the first wall surface.
When carrying out vertical distance measurement, for example the vertical distance between indoor ceiling and the ground, if ground is uneven, adopt laser range finder alone to hardly carry out the location of vertical direction, adopt the support after, can accurately realize vertical distance measurement. Specifically, the second pointer 330 points to the 90-degree scale direction of the angle scale 321 on the vertical indicating dial 320 to measure a first value, the vertical second pointer 330 rotates 180 degrees to point to the-90-degree direction of the angle scale 321, laser of the laser range finder 400 is transmitted downwards through the through hole T to measure a second value, the first value and the second value are added to obtain a vertical distance between two objects to be measured, and then the laser range finder 400 is positioned by using the laser range finder support of the embodiment, so that the measurement accuracy and efficiency are greatly improved.

In order to realize the azimuth measurement, as shown in fig. 4 to 6, a compass 240 and a horizontal indicating ring 250 are further disposed on the horizontal substrate 210, the horizontal indicating ring 250 is concentric with the horizontal indicating plate 220 and is located at the periphery of the horizontal indicating plate 220, and the horizontal indicating ring 250 is also horizontally rotatable around the vertical axis; the horizontal substrate 210 is uniformly distributed with outer ring angle scales 260 located at the periphery of the horizontal indicating ring 250, the horizontal indicating ring 250 is uniformly distributed with inner ring angle scales 270 located at the periphery of the horizontal indicating disc 220 and outer ring azimuth marks 280 located at the periphery of the inner ring angle scales 270, as shown in fig. 4, the distribution of the scales of the outer ring angle scales 260 is consistent with the distribution of the scales of the compass 240, the consistency here refers to the consistency of the minimum scale value, the scale division and the scales of each grid, and the distribution of the scales on the compass 240 is shown in fig. 5. For the rotation of the horizontal indicating ring 250 on the horizontal base plate 210, as shown in fig. 6, with the rotation of the horizontal indicating plate 220, a T-shaped guide slot 290 is correspondingly arranged on the horizontal base plate 210, and the horizontal indicating ring 250 is adapted to be placed in the guide slot, and the rotation thereof can be achieved by manual dialing.
Specifically, since the laser rangefinder bracket is placed in an arbitrary orientation, the horizontal indicator ring 250 is rotated to adjust its outer orientation mark 280 to be consistent with the orientation of the compass 240 by the actual orientation displayed by the compass 240 thereon, such as shown in fig. 4 and 5, the N-direction orientation scale 3 of the compass 240, the horizontal indicating ring 250 is rotated until the north of the outer orientation mark 280 points to the scale 3 on the outer angle scale 260, which is used as the reference for measuring the orientation of the object to be measured, then, the second pointer 330 of the vertical dial 320 points to the zero scale, and the horizontal dial 220 is rotated to read the orientation of the measuring line of the laser distance measuring instrument 400 in real time, the specific reading is combined with the inner circle angle scale 270 and the outer circle orientation mark 280 to perform reading, as shown in fig. 4, the direction pointed by the first pointer 230 is 60 ° north, and the direction of the object to be measured is determined to be 60 ° north.
