The two clamping seats 91 are used to limit the positions of the two sides of the rangefinder body 1. Under the action of the corresponding first springs 923, the pressure strips 922 press the rangefinder body 1 tightly against the mounting plate 7.

[0032] The rangefinder body 1 is placed on the mounting plate 7, two clamp seats 91 define two sides of the rangefinder body 1, and multiple pressing components 92 press the rangefinder body 1 onto the mounting plate 7 to stably fix the position of the rangefinder body 1, and are suitable for fixing rangefinders of various sizes.

[0033] When adjusting the position of the rangefinder body 1, the installation height of the rangefinder body 1 is adjusted by raising the bracket 2, and under the action of the leveling mechanism 3, it is ensured that the rangefinder body 1 is on a horizontal plane when in the initial position; then the measuring direction of the rangefinder body 1 is adjusted by adjusting the first positioning mechanism 5, and the inclination angle of the rangefinder body 1 is adjusted by adjusting the second positioning mechanism 8. Compared with the prior art, the rangefinder body 1 is stably installed to ensure the accuracy of its measurement data, and the installation position of the rangefinder body 1 is easily adjusted to measure data in different directions.

[0034] In a preferred embodiment, see Figure 4 , 5, a slide groove 911 is provided on the side away from each other of the two clamping seats 91, and the slide groove 911 extends along the length direction of the clamping seat 91. The lower end of the support frame 921 is slidably connected with the slide groove 911. Specifically, the slide groove 911 is a T-shaped groove, and a T-shaped slider 925 is provided at the lower end of the support frame 921. The T-shaped slider 925 is slidably connected with the T-shaped groove to adjust the position of the pressing assembly 92 on the clamping seat 91.

One group of spring positioning beads 24 corresponds to one positioning pin 23, so as to lock the positioning pin 23 in an upward or downward state. Specifically, a hinge seat 25 is disposed on the bottom plate 22. The positioning pin 23 is rotatably connected to the hinge seat 25. Two grooves 231 are formed on both side walls of the positioning pin 23. The two grooves 231 are symmetrically distributed along the rotation center line of the positioning pin 23. The spring positioning beads 24 are mounted on the hinge seat 25 and can be respectively inserted into the two grooves 231, so as to lock the positioning pin 23 in an upward or downward state. Figure 2 As shown, when the positioning pins 23 are arranged upward, it is suitable for the bottom plate 22 to be placed on a hard ground; Figure 1 As shown, when the positioning nails 23 are set downward, it is suitable for the base plate 22 to be placed on the mud, and the positioning nails 23 are inserted into the mud to improve the stability of the height adjustment bracket 2.

When leveling, the three adjusting nuts 34 are respectively rotated to adjust the extension length of the connected leveling screws 33, so that the upper plate 31 is parallel to the horizontal plane, ensuring that the rangefinder body 1 is located on the horizontal plane when it is in the initial position.

[0047] Optionally, three levels 35 arranged in a circular array are provided on the upper plate 31 , and the upper plate 31 can be adjusted to a horizontal state by looking at the levels 35 .

When the latching tooth block 53 is pulled backward, the second spring 54 is compressed, so that the latching tooth block 53 is away from the gear 51. At this time, the U-shaped frame 6 can be rotated to adjust the measuring direction of the rangefinder body 1; then the latching tooth block 53 is released, the second spring 54 is extended due to its own elastic force, and the latching tooth block 53 is engaged with the corresponding teeth of the gear 51 to lock the position of the U-shaped frame 6.

[0049] In order to facilitate pulling the latch block 53 , a shifting block 531 extending out of the mounting seat 52 is provided on the latch block 53 .
