[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] The present invention provides a sample square frame that is convenient for storage, as shown in Figure 1 , Figure 2 and Figure 5 . The sample square frame includes a first measuring rod 1, a sliding measuring rod 3 slidably installed inside the first measuring rod 1, a rotating block 5 fixedly installed at one end of the first measuring rod 1, a second measuring rod 2 arranged at the bottom of the first measuring rod 1, a connecting frame 6 fixedly installed at one end of the second measuring rod 2, and a fixing mechanism arranged on the sliding measuring rod 3 for fixing the sliding measuring rod 3. Uniformly distributed card slots are provided inside the first measuring rod 1. The rotating block 5 is rotationally connected inside the connecting frame 6 through an insertion rod. The bottom of the first measuring rod 1 is rotationally attached to the top of the second measuring rod 2.

[0026] The first measuring rod 1 and the second measuring rod 2 form a measuring rod group. When two measuring rod groups are fixed together, a sample square frame can be assembled. The first measuring rod 1 and the second measuring rod 2 are essentially the same parts, and both are internally provided with a slidable sliding measuring rod 3. The two can be rotated and attached together through the rotating block 5 and the connecting frame 6, reducing the space occupied. When assembling the sample square frame, the side length and coverage area of the sample square frame can be changed by moving the sliding measuring rod 3.

[0027] Furthermore, in order to fix the sliding measuring rod 3, as shown in Figure 2 , Figure 3 and Figure 4As shown, the fixing mechanism includes a clamping block 14 slidably installed inside the sliding measuring rod 3 and adapted to the internal card slot of the first measuring rod 1, a second spring 15 disposed on one side of the clamping block 14, a mounting shell 7 fixedly installed on the top of the sliding measuring rod 3, and a plug rod 8 movably installed inside the mounting shell 7. One end of the second spring 15 is fixedly connected to the sliding measuring rod 3, and the other end of the second spring 15 is fixedly connected to the clamping block 14. The plug rod 8 sequentially penetrates through the mounting shell 7 and the sliding measuring rod 3.

[0028] The card slot inside the first measuring rod 1 is set to be arc-shaped. When the sliding measuring rod 3 moves inside the first measuring rod 1 and is squeezed by the inner wall of the first measuring rod 1, the clamping block 14 will contract with the second spring 15 inside the sliding measuring rod 3. Since one end of the clamping block 14 in contact with the inner wall of the first measuring rod 1 is also arc-shaped, the movement of the sliding measuring rod 3 is not restricted. When the clamping block 14 reaches the position of the internal card slot of the first measuring rod 1, the acting force of the second spring 15 can make the clamping block 14 pop out and fit the card slot. By pressing the plug rod 8, the plug rod 8 abuts against the clamping block 14 to make the clamping block 14 immovable, thereby realizing the fixation of the sliding measuring rod 3.

[0029] Furthermore, in order to enable the plug rod 8 to fix or release the clamping block 14, as Figure 2 、 Figure 3 and Figure 4 shown, the fixing mechanism further includes a limit ring 9 fixedly installed on the plug rod 8, a moving ring 10 slidably installed inside the mounting shell 7 and fitting against the bottom of the limit ring 9, and a first spring 11 sleeved on the plug rod 8. One end of the first spring 11 is fixedly connected to the bottom of the moving ring 10, and the other end of the first spring 11 is fixedly connected to the top of the sliding measuring rod 3.

[0030] A first limit block 12 is fixedly connected to the plug rod 8, and a plugging slot 16 is formed on the clamping block 14. A second limit block 13 is fixedly connected inside the plugging slot 16.

[0031] The size of the plugging slot 16 on the clamping block 14 is adapted to the outer diameter of the first limit block 12 on the plug rod 8. When pressing and rotating the plug rod 8, the first limit block 12 is made to avoid the second limit block 13 and be plugged into the plugging slot 16. After the plug rod 8 is inserted into the plugging slot 16, it needs to be rotated once more so that the second limit block 13 abuts against the first limit block 12 to leave the plug rod 8 in the plugging slot 16. At this time, the plug rod 8 also completes the fixation of the clamping block 14. During the process of the plug rod 8 being inserted into the plugging slot 16, the limit ring 9 on the plug rod 8 can drive the moving ring 10 to move downward. When the moving ring 10 moves downward, it will compress the first spring 11. When it is necessary to release the clamping block 14, just rotate the plug rod 8 to make the first limit block 12 avoid the second limit block 13. Affected by the acting force of the first spring 11, the moving ring 10 can drive the plug rod 8 to pop out of the plugging slot 16 through the limit ring 9, thereby releasing the clamping block 14.

[0032] It should be noted that, for the convenience of users in using the quadrat, as Figure 1 , Figure 2 and Figure 5 shown, a strip-shaped sliding groove for the sliding of the mounting shell 7 is provided on the first measuring rod 1, evenly distributed scale grooves are provided on the first measuring rod 1, evenly distributed wire-sheathing grooves are provided on one side of the first measuring rod 1, and the same scale grooves as those on the first measuring rod 1 are provided on the sliding measuring rod 3.

[0033] The setting of the wire-sheathing grooves enables users to wind a string on the wire-sheathing grooves, and at the same time, in cooperation with the scale grooves, the grid visual estimation method is used for coverage estimation, which is convenient for users to use the quadrat.

[0034] Furthermore, in order to fix the quadrat during use, as Figure 1 , Figure 5 and Figure 6 shown, a plug-in frame 4 is fixedly connected to the rotating block 5, a plug-in frame 4 identical to that on the rotating block 5 is fixedly connected to the bottom of the connecting frame 6, and a connecting block is fixedly connected to one end of the sliding measuring rod 3.

[0035] Two groups of measuring rod sets can enclose a quadrat, and the splicing of the quadrat is realized by inserting the plug-in rod with the plug-in frame 4 into the inside of the connecting block. A fixing nail can be inserted into the inside of the plug-in frame 4, and the quadrat is fixed by inserting the fixing nail into the ground surface.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
