[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figures 3-5As shown, one embodiment of this utility model provides a portable grassland ecological monitoring quadrat tool, including a main connecting rod 1. A pull rod 2 is slidably connected to the inner wall of the main connecting rod 1. A secondary connecting rod 5 is provided at the bottom end of each pull rod 2. A locking block 4 is fixedly connected to the bottom end of each pull rod 2. A locking groove 6 is opened at the bottom end of each secondary connecting rod 5. The outer wall of the locking block 4 is provided on the inner wall of the locking groove 6, and the shape of the locking block 4 matches the shape of the locking groove 6. A spring 3 is fixedly connected to the outer wall of each pull rod 2. The other end of each spring 3 is fixedly connected to the top end of the main connecting rod 1 to limit the rotation of the secondary connecting rod 5. A limiting block 7 is slidably connected to the inner wall of each secondary connecting rod 5. A limiting groove 9 is opened on the upper side of the inner wall of the main connecting rod 1. The shape of the limiting block 7 matches the shape of the limiting groove 9. A spring 8 is fixedly connected to the bottom end of each limiting block 7. The other end of each spring 8 is fixedly connected to the bottom end of the secondary connecting rod 5 for disassembly and assembly between the main connecting rods 1.

[0028] Specifically, during disassembly, simply press the limiting block 7 to remove it from the limiting groove 9, disconnect the main connecting rods 1 on both sides, and simultaneously press the pull rod 2 to rotate the auxiliary connecting rod 5 in the opposite direction, thus rotating the auxiliary connecting rod 5 into the main connecting rod 1. This completes the disassembly. Furthermore, the limiting block 7 is large enough for the operator to press, and its design allows the auxiliary connecting rod 5 to be retracted into the main connecting rod 1 through rotation, reducing the tool's size and making it easier to carry. At the same time, during installation, the operation is simple and facilitates the installation of tools, thereby improving work efficiency and the accuracy of monitoring data.

[0029] Reference Figure 1 , Figure 2 and Figure 6 As shown, the outer wall of the auxiliary connecting rod 5 is rotatably connected to the inner wall of the main connecting rod 1. The inner wall of the auxiliary connecting rod 5 is provided with a T-slot 10. The inner wall of the T-slot 10 is provided with a T-block 11. The outer end of the T-block 11 is fixedly connected to a fixing plate 12. The inner wall of the fixing plate 12 is threadedly connected with a threaded rod 14. The shape of the T-block 11 matches the T-block 11. The top end of the threaded rod 14 is fixedly connected to a knob 13. The bottom end of the threaded rod 14 is fixedly connected to a drill bit 15 to fix the tool in the current position.

[0030] Specifically, by turning knob 13, the drill bit 15 is inserted into the ground, fixing the tool in its current position. This ensures that the tool remains stable throughout the monitoring period and does not move, enabling accurate analysis of changes in the grassland ecology of the area.

[0031] Working principle: First, during installation, press down on the pull rod 2. The pull rod 2 moves the locking block 4 downward, removing the locking block 4 from the slot 6 and releasing the restriction on the secondary connecting rod 5. Then, rotate the secondary connecting rod 5 outward 270 degrees. After rotation, release the pull rod 2. Spring 3 will then engage the locking block 4 in the slot 6, limiting the secondary connecting rod 5. Next, follow the same procedure to open the other main connecting rod 1, press the limiting block 7 in the secondary connecting rod 5, and install the secondary connecting rod 5. In another main connecting rod 1, and through spring 8, the limiting block 7 is inserted into the limiting groove 9. In the same way, the auxiliary connecting rod 5 on the other side is installed in the main connecting rod 1 to complete the installation. Next, when fixing, the T-block 11 can be inserted into the T-groove 10, the fixing plate 12 is installed on both sides of the tool, and the knob 13 is turned. The knob 13 drives the threaded rod 14 to rotate and move downward, which also drives the drill bit 15 to rotate and move downward, inserting the drill bit 15 into the ground to fix the tool.
