Detailed ways

In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific embodiments are described in detail with reference to the accompanying drawings.

As shown in Figures 1 to 11, a surrounding device for the investigation of a modular vegetation plot comprises several vertically extending quadrat columns 1, the bottom of the quadrat columns is fixedly provided with a tip 2, and the The top of the sample square column is provided with a recess 3 for plugging the tip of the previous sample square column, and each sample square column is fixed with hanging buckles 4 on the front, back, left, and right sides, which are used to hang the sample square rope 5 from four directions , and not easy to fall off, the two adjacent sample square columns are connected by the sample square ropes whose ends are wound on the hanging buckles, and several sample square columns are surrounded by the sample square ropes to form a circle.

In the embodiment of the present invention, the sample square column is a rectangular parallelepiped as a whole, and the long side has three specifications: 20cm (for investigating herbaceous communities), 40cm (for investigating shrub communities), 60cm (for investigating woody communities), and the column body The cross-section is a square with a side length of 1cm×1cm, and the hanging buckle is 3cm away from the top of the sample square column; the sample square rope can be designed as a colored flat strip with a fixed standard length, and one color represents a fixed length, for example, the red tape has a standard length of 10m , The standard length of the yellow belt is 5m, and the standard length of the blue belt is 1m. These colorful belts can be rolled into a ball or oblate shape for easy carrying.

In an embodiment of the present invention, the shape of the pointed portion is adapted to the shape of the concave portion.

In the embodiment of the present invention, the hanging buckle includes two L-shaped hanging rods 6, the short side ends of the two hanging rods are fixed with the sample square column, and the long sides of the two hanging rods are parallel to each other. And between the two short sides, there is a gap between the long sides of the two hanging rods and the inside and outside are staggered, and there is a gap between the long side end of the inner hanging rod and the short side of another hanging rod.

In the embodiment of the present invention, both ends of the sample rope are folded and sewn to form a closed connection ring 7 .

In the embodiment of the present invention, the enclosing device also includes several docking buckles 8, and the docking buckles are all composed of sub-buttons 9 and female buckles 10, and the sub-buttons and female buckles are provided with hanging buckles 11 , The butt buckle can be the plastic buckle on the schoolbag, or the buckle connected by mortise and tenon structure. The butt buckle can facilitate the temporary extension of the sample square rope to meet the needs of terrain changes.

In the embodiment of the present invention, when the mortise and tenon structure is used for connection, both the child buckle and the female buckle include an equilateral triangular prism 12, and a first equilateral triangle is formed in the center of one end face of the triangular prism along the axial direction. Slot 13, the first equilateral triangle slot is a quarter size of the end face, and the end face is a congruent equilateral triangle entity at the lower left, lower right, and top of the first equilateral triangular slot 14. The equilateral triangular entity above the end surface has a small triangular prism cut along its axial direction, and the length of the small triangular prism is less than the length of the first equilateral triangular slot; when buckling, the equilateral triangular entity above the sub-buckle Insert into the first equilateral triangle slot of the female buckle, the equilateral triangle entity above the female buckle is inserted into the first equilateral triangle slot of the sub-button, after the sub-button and the female buckle are inserted to the bottom, in the radial direction (sample square The degree of freedom of the rope stretching direction) is limited, the child buckle is connected with a sample square rope, the female buckle is connected with a sample square rope, the child buckle and the female buckle are connected, and the two sample square ropes are connected into one.

In the embodiment of the present invention, the buckle is fixed on the side of the triangular prism.
