[0018] The purpose of the present invention is to provide a portable forestry surveying tool to solve the problems existing in the prior art. On the basis of being able to survey various forestry data, the portable tool can also assist forestry workers in performing field operations.

[0019] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Embodiment 1

[0021] The forestry surveying portable tool of this embodiment includes an opaque ruler body, the material of the ruler body is 9Cr18MoV steel, and the ruler body is made by cutting a whole steel plate.

[0022] like Figure 1-2 As shown, in the forestry surveying portable tool of this embodiment, a first scale line 1 is arranged at the top of the front side of the ruler body, and the first scale line 1 and the ruler body form an L scale, which is used to measure height and distance based on the principle of similar triangles; a tree diameter scale line 19 is arranged at the top of the front side of the ruler body, and the tree diameter scale line 19 and the ruler body form a D scale, which is used to measure the circumference of the tree at breast height in conjunction with objects such as ropes and vines, so as to obtain the breast height diameter of the tree.

[0023] Reference Figure 1 An angle scale line 5 is also arranged at the lower left corner of the front side of the ruler body. The angle scale line 5, the ruler body and the auxiliary rope fixing hole 4 at the top of the ruler body form a slope measuring structure similar to that on the Brules altimeter, which can very conveniently perform slope measurement.

[0024] An observation ruler 2 is also provided on the top of the ruler body, and a gage cross-sectional area scale line 3 for measuring the gage cross-sectional area of ​​the forest stand is provided below the observation ruler 2. The width of the observation ruler 2 gradually decreases in the direction of increasing scale values ​​on the gage cross-sectional area scale line 3, and an auxiliary rope fixing hole 4 is provided in the gage cross-sectional area scale line 3. This tool is based on the gage tree measurement principle, with Fg=1 and L=50cm preset. The l corresponding to different slopes is represented by an opaque entity, and the corresponding l is marked with the corresponding slope. The gage cross-sectional area scale line 3 is defined as a G ruler.

[0025] During the operation, a 50cm long auxiliary rope can be reserved, and the auxiliary rope is naturally suspended from the origin of the slope ruler (angle scale line 5) to complete the slope measurement. Then, tighten the auxiliary rope, with one end against the eye and the other end placed at the position of the corresponding slope indicator of the G ruler, and compare the corresponding ruler width with the tree trunk diameter to complete the measurement.

[0026] For example, if the slope between the observation point and the measured tree is 30 degrees, slide one end of the auxiliary rope to the 30-degree mark on the G ruler, tighten the auxiliary rope to the eye, and compare the width of the "30" mark on the G ruler with the tree trunk. A long hole 18 is set in the middle of the ruler body. The widths of the left and right parts of the long hole 18 are different, and both ends of the long hole 18 are arc-shaped. The left and right parts of the long hole 18 can be used as a hexagonal bolt hole, so that the forestry survey portable tool can be used as a hexagonal bolt wrench; and there are six other hexagonal bolt holes of different sizes on the ruler body, such as Figure 1 and Figure 2 The first hexagonal bolt hole 10, the second hexagonal bolt hole 11, the third hexagonal bolt hole 12, the fourth hexagonal bolt hole 13, the fifth hexagonal bolt hole 14 and the sixth hexagonal bolt hole 17. Two square wrenches (not shown) of different sizes can also be set at the bottom end of the middle part of the long hole 18 to facilitate forestry workers to tighten the square screws.

[0027] The bottom end of the ruler is provided with a blunt tooth section 6, which can facilitate forestry workers to mark tree trunks. Of course, when forestry workers hold the upper part of the tool, the blunt tooth section 6 can also play a certain role in self-defense, or use the forestry surveying portable tool of this embodiment as a life-saving hammer. Figure 1 ) is provided with an oblique angle, so the lower left corner of the forestry surveying portable tool of this embodiment can be used as a hammer head for striking work.

[0028] like Figure 1 As shown, two extension rods are provided at the top and bottom of the right end of the ruler body, a flat screwdriver 9 is provided at the end of one extension rod, and a hexagonal column 8 is provided at the end of the other extension rod, and the hexagonal column 8 and the extension rod form a hexagon socket bolt wrench; a fifth hexagonal bolt hole 14 is formed between the two extension rods. Through holes are provided on the two extension rods, namely a first through hole 15 and a second through hole 16, respectively. When necessary, elastic rubber bands can be fixed on the ruler body through the first through hole and the second through hole to form a slingshot, which is convenient for forestry workers to launch stones and other objects to obtain samples of leaves, fruits, etc. at high places.

[0029] An arc-shaped recessed portion is also provided at the bottom of the ruler body, and a bottle-lifting protrusion 7 is provided at the end of the arc-shaped recessed portion. The portable forestry surveying tool of this embodiment can easily replace the bottle opener by utilizing the bottle-lifting protrusion 7, and a recess is also provided in the middle of the bottle-lifting protrusion 7, so that the portable forestry surveying tool of this embodiment can also utilize the bottle-lifting protrusion 7 for nail removal.

[0030] The forestry surveying portable tool of the present embodiment can also be wound with a rope to be used as a descender or to assist in climbing. Of course, the forestry surveying portable tool of the present embodiment can also be used to carry heavy objects.
