[0038] In this embodiment, as Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 shown, a third oil cylinder 7267 is fixed to one side of the support frame 6, and the bottom of the third oil cylinder 7267 is connected to the top of the second oil cylinder 7261 through a first connecting pipe 7265. A first valve 7266 is rotatably connected inside the first connecting pipe 7265. A third piston 7268 is rotatably connected inside the third oil cylinder 7267. The first valve 7266 is initially in a vertically open state. The first connecting pipe 7265 serves to connect the second oil cylinder 7261 and the third oil cylinder 7267. When the second piston 7263 moves upward, the third piston 7268 rotates under the action of the oil pressure, thereby driving the laser rangefinder body 8 to rotate, facilitating the adjustment of the angle of the laser rangefinder body 8.

[0039] In this embodiment, as Figure 2 , Figure 3 , Figure 6 and Figure 9As shown, the top of the second oil cylinder 7261 is connected to the bottom of the first oil cylinder 4 through the second connecting pipe 7269, and a second valve 72610 is rotatably connected in the second connecting pipe 7269. A third belt transmission assembly 72612 is rotatably connected to the front inner wall of the support box 1, and one side of the rear end face of the third belt transmission assembly 72612 is connected to the first valve 7266 through a connecting shaft 72611. The other side of the rear end face of the third belt transmission assembly 72612 is connected to the second valve 72610 through a connecting shaft 72611. A second knob 72613 is fixed to the front side of the third belt transmission assembly 72612. The second knob 72613 penetrates through the front side of the support box 1, and a first marking protrusion 72614 is fixed to the front end face of the second knob 72613. Two second marking protrusions 9 are fixed to the front side of the support box 1. The first valve 7266 is initially in a vertically open state, and the second valve 72610 is initially in a vertically closed state. The first marking protrusion 72614 is aligned with one of the second marking protrusions 9. At this time, the first connecting pipe 7265 is open, and the second connecting pipe 7269 is closed. The hydraulic oil in the second oil cylinder 7261 can be pressed into the third oil cylinder 7267, and the third piston 7268 can rotate under the action of the oil pressure, facilitating the adjustment of the angle. When holding the second knob 72613 and rotating the third belt transmission assembly 72612, the two connecting shafts 72611 rotate, the first valve 7266 rotates to a horizontally closed state, and the second valve 72610 rotates to a horizontally open state. The first marking protrusion 72614 is aligned with the other second marking protrusion 9. The first connecting pipe 7265 is closed, and the second connecting pipe 7269 is open.

[0040] According to another aspect of the present invention, a laser ranging method is provided, including the following steps:

[0041] S1. Install the base 2 at the required location. Hold the first knob 702 and rotate the sleeve 701, the square rod 703, the worm 712, the worm gear 713, the first belt transmission assembly 714, the first gear 715, and the second gear 716. The rotation of the first gear 715 drives the rotation of the third gear 723, the second belt transmission assembly 724, and the lead screw 7262. The second piston 7263 moves upward. The second oil cylinder 7261 stores hydraulic oil, and the hydraulic oil is pressed into the third oil cylinder 7267. The third piston 7268 rotates, thereby roughly adjusting the angle of the laser rangefinder main body 8.

[0042] S2. Hold the handle 705 and the pull rod 706 at the same time to pull the movable frame 704 to the left and make the third gear 723 meshed and connected with the second gear 716. Then repeat the above operation. The rotation of the second gear 716 drives the rotation of the third gear 723, thereby finely adjusting the angle of the laser rangefinder main body 8.

[0043] S3. After completing the angle adjustment operation of the laser rangefinder main body 8, push the movable frame 704 to the right to engage the third gear 723 with the first gear 715. Hold the second knob 72613 and rotate the third belt drive assembly 72612. The two connecting shafts 72611 rotate, and the first valve 7266 and the second valve 72610 rotate simultaneously. The first valve 7266 closes, and the second valve 72610 opens. Then continue to rotate the first gear 715, the second piston 7263 moves upward, the hydraulic oil is pressed into the first oil cylinder 4, and the first piston 5 moves upward to roughly adjust the height of the laser rangefinder main body 8. Pull the movable frame 704 to engage the third gear 723 with the second gear 716. The rotation of the second gear 716 drives the rotation of the third gear 723 to facilitate the fine adjustment of the height of the laser rangefinder main body 8;

[0044] S4. Finally, move the movable frame 704 and place it between the first gear 715 and the second gear 716. The first lock block 708 automatically snaps into the middle card slot 711 to achieve the locking effect. Then use the laser rangefinder main body 8 to measure the distance;

[0045] S5. After using the laser rangefinder main body 8, manually pull the pull ring 722 and the second connecting rope 721 to make the first lock block 708 leave the card slot 711. Then press the pressing plate 7264. The second piston 7263 moves downward, and the first piston 5 moves downward to reset. After switching the opening and closing of the first valve 7266 and the second valve 72610, continue to press the pressing plate 7264, and the second piston 7263 continues to move downward, and the third piston 7268 rotates back to reset.

[0046] The working principle of this device is as follows: First, use the mounting holes 3 and external bolts to install the base 2 at the required location. When holding the first knob 702 and rotating the sleeve 701, the square rod 703 and the worm 712 rotate, and the worm gear 713, the first belt drive assembly 714, the first gear 715, and the second gear 716 rotate. When holding the handle 705 and the pull rod 706, the first lock block 708 moves downward under the pulling action of the first connecting rope 707 and leaves the card slot 711, thus unlocking the handle 705. After that, the movable frame 704, the first gear 715, and the second gear 716 can be pushed and pulled left and right as a whole. After releasing the handle 705 and the pull rod 706, the first lock block 708 automatically pops up and snaps into the corresponding card slot 711. The number of teeth of the second gear 716 is less than that of the first gear 715. At first, the first gear 715 is meshed and connected with the third gear 723, and the third gear 723 can rotate with the rotation of the first gear 715, achieving a rough adjustment effect. After moving the movable frame 704 to mesh the second gear 716 with the third gear 723, the third gear 723 can rotate with the rotation of the second gear 716, achieving a fine adjustment effect. The rotation of the third gear 723 drives the second belt drive assembly 724 and the lead screw 7262 to rotate, and the second piston 7263 and the pressing plate 7264 move upward. The second oil cylinder 7261 stores hydraulic oil. The first valve 7266 is in a vertically open state, and the second valve 72610 is in a vertically closed state. The hydraulic oil in the second oil cylinder 7261 is pressed into the third oil cylinder 7267 through the first connecting pipe 7265. The third piston 7268 rotates to drive the laser rangefinder body 8 to rotate, thereby adjusting the angle of the laser rangefinder body 8. When holding the second knob 72613 and rotating the third belt drive assembly 72612, the first valve 7266 and the second valve 72610 rotate with their respective corresponding connecting shafts 72611. The first valve 7266 turns to a horizontally closed state, and the second valve 72610 turns to a horizontally open state. When the second piston 7263 continues to move upward, the hydraulic oil can be pressed into the first oil cylinder 4. The first piston 5 moves upward under the action of the oil pressure, and the support frame 6 and the laser rangefinder body 8 move upward accordingly, facilitating the adjustment of the height of the laser rangefinder body 8. By moving the movable frame 704, the first gear 715 and the second gear 716 can be switched for use, facilitating the realization of rough adjustment and fine adjustment. Then move the movable frame 704 and make the third gear 723 located between the first gear 715 and the second gear 716. The third gear 723 is not meshed and connected with the first gear 715 and the second gear 716, and the second lock block 720 automatically snaps into the bushing 725, achieving a locking effect. Subsequently, the laser rangefinder body 8 can be used to measure the distance. Before resetting, first pull the pull ring 722 and the second connecting rope 721 and make the second lock block 720 leave the bushing 725. Then manually press the pressing plate 7264, the second piston 7263 moves downward, the first piston 5 resets, and then switch the opening and closing of the first valve 7266 and the second valve 72610 by rotating the third belt drive assembly 72612.Continue to press down the pressing plate 7264, the second piston 7263 continues to move downward, the third piston 7268 rotates and returns to its original position, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0047] In summary, the laser ranging device and the ranging method achieve the purpose of adjusting the angle and height, rough adjustment and fine adjustment, and switching the direction in sequence with the same drive, meeting the usage requirements of people.

[0048] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
