A connecting rod 14 is installed for sliding inside the movable groove 12. The shape of the connecting rod 14 is L-shaped, and one side of the connecting rod 14 is fixedly connected to the left sides of the two guide rods 13. By setting a supporting mechanism, the device is placed on the ground, and the connecting rod 14 is moved to the left to drive the two wedge blocks 9 to move to the left, and the supporting plate 3 is moved downward. After the supporting plate 3 is moved between the wedge block 9 and the fixed block 10 on the lower side, the moving rod is released, and the wedge block 9 is popped out by the rebound force of the spring 11. Due to the rotational connection of the first connecting rod 4 and the second connecting rod 5, the first connecting rod 4 and the second connecting rod 5 are in the shape of a right triangle. Since the first connecting rod 4 and the second connecting rod 5 are correspondingly provided with multiple ones, the device is stably supported, thereby avoiding the problem of unstable support for the rangefinder 7 after the staff holds the device for a long time;

[0033] Reference Figure 1-4 The rotating mechanism includes a rotating shell 6 and a rangefinder 7. The rotating shell 6 is rotatably mounted inside the support column 1. The rangefinder 7 is mounted inside the rotating shell 6. A rotating rod 15 is rotatably mounted inside the support column 1. A first meshing tooth 16 is fixedly mounted on the surface of the rotating rod 15. A handle 17 is fixedly mounted on the front side of the rotating rod 15. A second meshing tooth 18 is fixedly mounted on the surface of the rotating shell 6. The first meshing tooth 16 and the second meshing tooth 18 are meshed and connected. A plurality of positioning grooves 19 are opened on the front side of the support column 1. The handle 17 slides inside A positioning pin 20 is installed, and the positioning pin 20 passes through the interior of the support column 1. By setting a rotating mechanism, the positioning pin 20 is pulled out of the positioning groove 19, and the handle 17 is turned to drive the rotating rod 15 to rotate. Due to the meshing connection between the first meshing tooth 16 and the second meshing tooth 18, the rotating rod 15 drives the rotating shell 6 to rotate. After the rotating shell 6 drives the rangefinder 7 to reach a vertical state, the positioning pin 20 is inserted into the corresponding positioning groove 19, thereby achieving the need for the rangefinder 7 to maintain a vertical state when in use, thereby improving the test accuracy.

[0034] Specifically, the working process or working principle of the portable tree height meter is as follows: when in use, put the device on the ground, move the connecting rod 14 to the left, drive the two wedge blocks 9 to move to the left, move the support plate 3 downward, move the support plate 3 between the wedge block 9 and the fixed block 10 on the lower side, and then release the moving rod. The wedge block 9 is popped out by the rebound force of the spring 11. Due to the rotational connection between the first connecting rod 4 and the second connecting rod 5, the first connecting rod 4 and the second connecting rod 5 are in the shape of a right triangle. Since the first connecting rod 4 and the second connecting rod 5 are correspondingly arranged in multiple numbers, they provide stable support for the device. Pull out the positioning pin 20 from the positioning groove 19, turn the handle 17, and drive the rotating rod 15 to rotate. Due to the meshing connection between the first meshing tooth 16 and the second meshing tooth 18, the rotating rod 15 drives the rotating shell 6 to rotate. After the rotating shell 6 drives the rangefinder 7 to reach a vertical state, the positioning pin 20 is inserted into the corresponding positioning groove 19.

[0035] It should be noted that the rangefinder 7 is a device or equipment existing in the prior art, or a device or equipment that can be implemented in the prior art. Its power supply, specific composition and principle are clear to those skilled in the art, so they are not described in detail.
