It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0024] Example 1: A rangefinder for outdoor engineering, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, it includes a rangefinder body 15, a mounting frame 1, a push block 2, a guide rod 6, a reset spring 7, a clamping block 8, a compression spring 9, a buckle 10, a pin lock 11, a rotating shaft 12, a chuck 13, a block 14 and an adjustment mechanism. The push block 2 is slidably connected to the upper part of the mounting frame 1, the rotating shaft 12 is rotatably connected to the inner upper part of the push block 2, the chuck 13 is connected to the rotating shaft 12, and spherical grooves are provided on both sides of the lower part of the chuck 13. The inner rear upper part of the push block 2 is connected to the pin lock 11, and the pin lock 11 consists of a locking spring and a ball block. The inner rear upper part of the push block 2 is connected to the locking spring, and the upper part of the locking spring is connected to the ball block. The ball block is slidably connected to the push block 2, and the ball block and the chuck 13 are connected. shaped groove snap fit, the card block 14 is connected to the upper part of the chuck 13, the card block 14 is snapped with the rangefinder body 15, the inner lower part of the mounting frame 1 is connected to the left and right sides of the guide rod 6, the guide rod 6 is slidably connected with the clamping block 8, the clamping block 8 is slidably connected to the mounting frame 1, and a return spring 7 is wound between the side of the clamping block 8 away from each other and the mounting frame 1, and the return spring 7 is wound around the adjacent guide rod 6. The front upper part of the clamping block 8 is slidably connected with a buckle 10, and the rear part of the buckle 10 is connected to the adjacent clamping block 8 with a compression spring 9. The buckle 10 is snap-fitted with the mounting frame 1, and the front part of the mounting frame 1 is provided with an adjustment mechanism for facilitating people to adjust the rangefinder body 15.

[0025] like Figure 1 、 Figure 2 and Figure 3As shown, the adjustment mechanism includes a rack 3, a gear 4 and a turntable 5. The turntable 5 is rotatably connected to the front of the mounting frame 1, the gear 4 is connected to the rear of the turntable 5, the rack 3 is connected to the lower part of the push block 2, the rack 3 and the gear 4 are engaged, and the rack 3 is slidably connected to the mounting frame 1.

[0026] When using this outdoor engineering rangefinder, first, you need to install the mounting frame 1 on the tripod. In the initial state, the mounting frame 1 is stuck with the buckle 10, so people have to press the buckle 10 backward by hand, so that the compression spring 9 is compressed, and then keep the buckle 10 retracted into the mounting frame 1, and move the clamping block 8 to the side away from the rangefinder body 15. As a result, the buckle 10 and the compression spring 9 both move to the side away from the rangefinder body 15, and the reset spring 7 is compressed, so that the upper part of the tripod is located between the two clamping blocks 8. Then release the clamping block 8. Under the action of the reset spring 7, the clamping block 8 moves to the side close to the rangefinder body 15. As a result, the buckle 10 and the compression spring 9 both move to the side close to the rangefinder body 15, and the clamping block 8 can be Under the action of the return spring 7, the upper part of the tripod is clamped, so that the mounting bracket 1 is installed on the upper part of the tripod. Then, the tripod is placed at a designated location, and people can then adjust the direction of the rangefinder body 15. First, people can manually rotate the turntable 5, so that the turntable 5 drives the gear 4 to rotate. Then, driven by the gear 4, the rack 3 drives the push block 2 to move left and right, thereby causing the rotating shaft 12, the chuck 13, the pin lock 11, the clamping block 14 and the rangefinder body 15 to move left and right together. When the rack 3 moves to the left, the rack 3 will extend from the left part of the mounting bracket 1. When the rack 3 moves to the right, the rack 3 will extend from the right part of the mounting bracket 1. After adjusting the left and right positions of the rangefinder body 15, people can further adjust the angle of the rangefinder body 15. In order to make the rangefinder body 15 rotate, people can directly turn the card block 14 with a little force, so that the card block 14 drives the rangefinder body 15 to rotate, and under the drive of the card block 14, the chuck 13 and the rotating shaft 12 also rotate together. When the spherical groove of the chuck 13 rotates to the ball block that is not facing the pin lock 11, the chuck 13 will squeeze the ball block downward, so that the locking spring of the pin lock 11 is compressed. When the chuck 13 rotates to the ball groove that is facing the ball block again, the ball block will move upward and be locked in the spherical groove under the action of the locking spring. In this way, the chuck 13 can be limited by the pin lock 11, so that the rangefinder body 15 will not rotate due to a slight touch. At this time, the lens of the rangefinder body 15 is facing backward. When the rangefinder body 15 needs to be further rotated, it is necessary to turn it with a little force. Move the clamping block 14 and repeat the above process, then people can measure the distance. After the distance measurement is completed, the mounting frame 1 needs to be removed from the tripod, so people need to manually move the clamping block 8 to the side away from the rangefinder body 15, so that the buckle 10 and the compression spring 9 both move to the side away from the rangefinder body 15, and the return spring 7 continues to compress, so that the buckle 10 pops out from the side of the mounting frame 1 away from the rangefinder body 15 under the action of the compression spring 9, and then the mounting frame 1 can be moved upward, and then the buckle 10 is pressed backward by hand, so that the clamping block 8 moves to the side close to the rangefinder body 15 under the action of the return spring 7 and is reset. So the buckle 10 and the compression spring 9 both move to the side close to the rangefinder body 15 and are reset.

[0027] Example 2: Based on Example 1, Figure 1 、 Figure 2 and Figure 6 As shown, it also includes a rotating rod 16 and a baffle 17. The rotating rods 16 are symmetrically connected to the left and right sides of the upper part of the rangefinder body 15 in a front-to-back rotational manner, and the baffle 17 for blocking part of the light is rotatably connected between the upper parts of the rotating rods 16.

[0028] In order to prevent strong light from affecting the distance measurement of the rangefinder body 15, people can manually rotate the baffle 17 to rotate the rotating rod 16 accordingly. In this way, some light can be blocked by the baffle 17 to prevent the light from directly hitting the lens of the rangefinder body 15. When the distance measurement is completed, the baffle 17 is manually rotated in the opposite direction to reset the baffle 17 in the opposite direction, and the rotating rod 16 is then rotated in the opposite direction to reset.

[0029] like Figure 1 、 Figure 2 and Figure 6 As shown, a level bubble 18 is also included. The upper front side of the rangefinder body 15 is connected with the level bubble 18 for checking whether the rangefinder body 15 is placed horizontally.

[0030] In order to determine whether the rangefinder body 15 is placed horizontally, people can observe the level bubble 18 to see whether the bubble in the level bubble 18 is located in the middle position of the level bubble 18. If the bubble is in the middle position of the level bubble 18, it means that the rangefinder body 15 is placed horizontally. If not, it means that the rangefinder body 15 is not placed horizontally and the rangefinder body 15 needs to be further adjusted.

[0031] like Figure 1 As shown, it also includes a lighting lamp 19. Two lighting lamps 19 are connected to the middle position of the front of the mounting frame 1. The two lighting lamps 19 are distributed on the left and right, and the lighting lamps 19 are used for supplementary lighting.

[0032] In order to adjust the rangefinder body 15 and measure the distance on a cloudy day, people can turn on the lighting lamp 19 to provide additional light, and then turn off the lighting lamp 19 after the distance measurement is completed.

[0033] like Figure 1 and Figure 3 As shown, a handle for easy grasping is connected to the right front portion of the turntable 5.

[0034] The handle has a function of being easy to grasp. In order to conveniently rotate the turntable 5 , people can hold the handle and rotate the turntable 5 .

[0035] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
