At this time, the toggle rod will limit the toggle frame so that the toggle frame is parallel to the sliding frame. At this time, the sliding frame can move freely. When the limit rod moves to the reset groove, it drives the limit rod to move downward. The limit rod moves downward so that the toggle rod is separated from the lifting groove and contacts with the toggle groove again. At this time, the toggle frame is reset by the second torsion spring, so that the limit rod is in the first circular arc groove again, which can help the support rod to remain stable when adjusting the angle and reduce the measurement error caused by vibration or slight movement.

[0030] A method for fine-tuning a laser horizontal rangefinder comprises the following steps: Step 1: First, the fine-tuning device can be used alone or installed on the supporting device according to the usage. By rotating the adjusting rod 10, the spiral groove rotates, and the spiral groove rotates to drive the gear 12 to rotate. The gear 12 rotates to drive the connecting plate 11 to rotate. The connecting plate 11 rotates to drive the rangefinder body 2 to rotate, and the rangefinder body 2 can be fine-tuned. Step 2: If a support device is required, the mounting column 14 is mounted to the inner wall of the hollow column 15, and the fine-tuning device and the support device are fixedly connected by fitting the plug block 16 with the docking groove.

At the same time, the block 28 can prevent the screw rod 24 from being accidentally touched by external force and causing rotation. Step three: Through the auxiliary device, the sliding frame 33 is driven to move when the support rod 23 rotates, and the movement of the sliding frame 33 drives the rotating frame 32 to rotate. At this time, the movement of the sliding frame 33 can be limited by the limit rod 310 and the arc groove. When the sliding frame 33 moves to the moving distance, it will move and reset through the reset groove 1 34 and the reset groove 2 35. At this time, the lever 36 is inserted into the pulling groove 38 to limit the toggle frame 37. At this time, the sliding frame 33 can move at will, and the support rod 23 can be rotated.
[0031] When the present embodiment is working, the fixing button 21 is moved by moving the mounting plate 20, and the fixing button 21 is moved to move the rotating button 22, and the mounting plate 20 is supported by the supporting rod 23 driven by the rotating button 22, and the screw rod 24 is rotated by rotating the limiting plate 26, and the screw rod 24 is rotated to rotate the spiral groove 2, and the spiral groove 2 is rotated to drive the connecting frame 25 to move up and down along the circumferential surface of the screw rod 24, and the connecting frame 25 is moved when the connecting frame 25 moves upward, and the movement of the connecting frame 25 causes the support angle of the supporting rod 23 to change, and when the rotation stops, the limiting plate 26 cannot be rotated by inserting the block 28 into the limiting groove, so as to prevent the screw rod 24 from rotating due to an external force, resulting in a change in the adjustment angle, so that the measurement of the rangefinder body 2 is deviated; The sliding frame 33 is driven to move by the angle change of the support rod 23, and the movement of the sliding frame 33 drives the rotating frame 32 to rotate. The movement of the sliding frame 33 drives the toggle frame 37 to move, and the movement of the toggle frame 37 drives the limit rod 310 to move. The limit rod 310 will move along the arc slot and limit the movement of the sliding frame 33 through the arc slot. Whenever the limit rod 310 moves along the arc slot, it will drive the toggle frame 37 to rotate upward, and the rotation of the toggle frame 37 drives the limit rod 310 to move to the next arc slot. At this time, the toggle rod 36 is always in the toggle slot 39. When the limit rod 310 moves to the reset slot 2 35, the limit rod 310 will move upward. When the toggle frame 37 is rotated upward significantly until the toggle rod 36 is inserted into the lifting groove 38, the toggle rod 36 will limit the toggle frame 37 so that the toggle frame 37 is parallel to the sliding frame 33. The sliding frame 33 can move at will, and when the limit rod 310 moves to the reset groove 34, the limit rod 310 is driven to move downward. The limit rod 310 moves downward so that the toggle rod 36 is disengaged from the lifting groove 38 and re-contacts the toggle groove 39. At this time, the toggle frame 37 is reset by the No. 2 torsion spring, so that the limit rod 310 is back in the first arc groove, which can help the support rod 23 to remain stable when adjusting the angle and reduce the measurement error caused by vibration or slight movement.

9. A method for using a laser horizontal rangefinder fine-tuning mechanism, using the laser horizontal rangefinder mechanism of claim 8, characterized in that: The following steps are involved: Step 1: First, the fine-tuning device can be used alone or installed on the supporting device according to the usage. By rotating the adjusting rod (10), the spiral groove rotates, and the rotation of the spiral groove drives the gear (12) to rotate. The rotation of the gear (12) drives the connecting plate (11) to rotate. The rotation of the connecting plate (11) drives the rangefinder body (2) to rotate, thereby completing the fine-tuning of the rangefinder body (2); Step 2: If a support device is required, the mounting column (14) is mounted on the inner wall of the hollow column (15), and the fine-tuning device and the support device are fixedly connected by fitting the plug block (16) with the docking groove. The fine-tuning device and the support device can be disassembled by the latch (110). The support angle of the support rod (23) can be adjusted by rotating the screw rod (24). At the same time, the clamping block (28) can prevent the screw rod (24) from being accidentally touched by external force and causing rotation. Step three: By means of the auxiliary device, when the support rod (23) rotates, the sliding frame (33) is driven to move, and the movement of the sliding frame (33) drives the rotating frame (32) to rotate. At this time, the movement of the sliding frame (33) can be limited by the limit rod (310) and the arc groove. When the sliding frame (33) moves to the moving distance, it will move and reset through the reset groove 1 (34) and the reset groove 2 (35). At this time, the lever (36) is inserted into the lifting groove (38) to limit the toggle frame (37). At this time, the sliding frame (33) can be moved at will, and the support rod (23) can be rotated.
