DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-Figure 3 This application is described in further detail.

[0021] Embodiment 1

[0022] Reference Figure 1-Figure 3A laser rangefinder for outdoor measurement includes a fixed sleeve 1, an extension rod 2 is welded at the bottom end of the fixed sleeve 1, a weight-increasing rod 12 is welded at the bottom end of the extension rod 2, a rotating shaft 3 is welded in the middle of the extension rod 2 in order to move the center of gravity of the ranging mechanism downward, both ends of the outer side of the rotating shaft 3 are rotatably connected with an extension frame 4 through bearings, a vertical adjustment limiter 5 is installed on the outer side of one end of the extension frame 4, one end of the vertical adjustment limiter 5 is fitted with the outer side of one end of the rotating shaft 3, the bottom ends of the two extension frames 4 are rotatably connected with a connecting flip plate 6, a flip limiter 7 is installed at the outer bottom of one end of the extension frame 4 at the rotating connection of the connecting flip plate 6, and one end of the flip limiter 7 is connected to the connecting flip plate 6 relative to the outer The extension frame 4 is connected to the rotating connection of the support mechanism for longitudinal adjustment, and a support frame connecting seat 8 is welded to the bottom end of the connecting flip plate 6. Both ends of the support frame connecting seat 8 are rotatably connected to support frames 9. In order to adjust the lateral angle of the support mechanism, a support frame limiter 10 is installed on the outside of the support frame connecting seat 8 at the rotating connection of the support frame 9. The vertical adjustment limiter 5, the flip limiter 7 and the support frame limiter 10 are all bolt limiters. One end of the support frame limiter 10 is connected to the rotating connection of the support frame 9 relative to the support frame connecting seat 8. The bottom ends of the four support frames 9 are welded with ground plates 11, and a rangefinder 13 is sleeved on the inner side of the fixed sleeve 1.

[0023] Working principle: First, the operator loosens the four support frame limiters 10 in sequence, and then expands the four support frames 9 outward relative to the support frame connecting seat 8, so that the relative angle between the support frame 9 and the support frame connecting seat 8 is rotated from a parallel state to a fixed angle and then stops, and then tightens the support frame limiter 10 installed on the outside of the support frame connecting seat 8, and then adjusts the remaining three support frames 9 in sequence. After the angles of the four support frames 9 are all adjusted, the longitudinal adjustment of the support mechanism can be completed, and the operator then loosens the flip limiter 7 installed on the bottom outside one end of the extension frame 4, and then rotates the two support frame connecting seats 8 outward;

[0024] The support frame connecting seat 8 is rotated from being parallel to the extension frame 4 to having an angle with the extension frame 4, and the angle is appropriately adjusted according to the terrain. After the entire support mechanism can be placed stably, the operator tightens the flip limiter 7. During this period, the embedded piece 11 installed at the bottom of the support frame 9 will be inserted into the ground, so that the support mechanism can be more stable. Then the operator loosens the vertical adjustment limiter 5. At that time, the rotating shaft 3 that loses the limit will rotate, and at the same time drive the extension rod 2 welded on its outside to rotate. And because the weight-increasing rod 12 is welded at the bottom end of the extension rod 2, the center of gravity of the extension rod 2 is at the bottom. Through the effect of the ground attraction, the extension rod 2 can be reset after rotating for a period of time, and at the same time achieve a vertical state. The rangefinder 13 installed at the top of the extension rod 2 will also be in a vertical state at that time, and it will be more accurate and the process will be faster. Then the operator tightens the vertical adjustment limiter 5 after the extension rod 2 stops rotating. This setting can make the adjustment of the rangefinder more accurate and faster.

[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
