For example, a tree branch angle measuring device with publication number CN106441037A includes a protractor, a wireless lighting camera, and a rhombus body with a four-link structure formed by four measuring plates connected by connecting hinges and measuring hinges. The outer surfaces of the two measuring plates below the rhombus body are fixedly connected to toothed positioning forks, and the connection between the two measuring plates below is the measuring hinge; a crossbar of a hinged support connecting device is provided on the upper measuring plate, and the crossbar is fixedly connected to a vertical telescopic rod, and a liquid crystal image receiver is fixed on the lowest rod of the vertical telescopic rod; at the same time, the bottom edge of the protractor is fixedly connected to the measuring plate, and the two measuring plates above are fixedly connected to the bottom edge of the protractor.

Specifically, the first end of the elastic telescopic rod 1 with the first distance measuring component is rotatably connected to the bottom end of the stick rod 2 through the second elongated longitudinal axis 9. The second elongated longitudinal axis 9 is equivalent to an axis and plays a role of rotation connection. In addition, the second elongated longitudinal axis 9 itself is relatively long, and a longer part thereof extends out of the connection between the first end of the elastic telescopic rod 1 with the first distance measuring component and the bottom end of the stick rod 2. The first end of the cross bar 3 is rotatably connected to the top end of the stick rod 2 through the first elongated longitudinal axis 8. The first elongated longitudinal axis 8 It is equivalent to an axis and plays a role of rotational connection, and the first extended longitudinal axis 8 itself is relatively long, with a longer part extending out of the connection between the first end of the cross bar 3 and the top end of the sticking rod 2. A horizontal reference member 5 is fixedly installed on the cross bar 3, and the horizontal reference member 5 can be an ordinary level for the operator to determine whether the cross bar 3 is in a horizontal state.

[0022] The first distance measuring device provided on the elastic telescopic rod 1 with the first distance measuring device can measure the length of the elastic telescopic rod 1 with the first distance measuring device itself. The optical distance measuring module 6 is used to measure the distance between the first end on the cross bar 3 and the connection between the elastic telescopic rod 1 with the first distance measuring device and the cross bar 3. The distance of the sticking rod 2 itself remains unchanged, so that the angle of the triangle formed by the sticking rod 2, the elastic telescopic rod 1 with the first distance measuring device, and the cross bar 3 can be calculated.

[0023] When measuring, the user manipulates the stick rod 2, the elastic telescopic rod 1 with the first distance measuring member, and the cross bar 3 to form a triangular structure, so that the first elongated longitudinal shaft member 8 and the second elongated longitudinal shaft member 9 are aligned with the first elongated longitudinal shaft member 8 and the second elongated longitudinal shaft member 9.

Through simple setting / conversion calculation, the optical ranging module 6 can measure the distance between the first end on the cross bar 3 and the connection between the elastic telescopic rod 1 with the first ranging component and the cross bar 3. For example, the distance b between the first end on the cross bar 3 and the connection between the elastic telescopic rod 1 with the first ranging component and the cross bar 3=the distance b2 between the sliding connecting member 7 and the end of the sliding hole 4+the distance b1 between the position where the optical ranging module 6 is located (the end position of the sliding hole 4) and the end of the sticking rod 2 is a fixed value.
