[0009] Preferably, a pull ring is fixedly connected to one end of the stop rod away from the limiting sleeve.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] The portable grassland vegetation survey sampling device can assemble the connecting mechanism and the positioning block by screwing the locking rod at one end of the connecting rod into the locking groove on the positioning block. The position of the connecting rod in the hollow tube can be slid according to actual usage requirements to adjust the length. After adjusting to the appropriate length, the stop rod on the support plate is slid into the corresponding stop groove of the connecting rod to fix the position of the connecting rod. The limit sleeve on the stop rod can prevent the stop rod from disengaging from the support plate. The utility model is convenient for on-site assembly, easy to carry, and its length can be adjusted according to requirements, which is suitable for popularization and use.

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0017] Please refer to Figures 1 - 3, an embodiment provided by the present utility model: a portable grassland vegetation survey and sampling device, including four positioning blocks 1 and a plurality of connecting mechanisms connecting the four positioning blocks. The plurality of connecting mechanisms each include a hollow tube 2. Connecting rods 3 are slidably inserted at both ends of the hollow tube 2. One end of the connecting rod 3 is fixedly connected with a locking rod 4. The outer side wall of the locking rod 4 is provided with an external thread. The positioning block 1 is provided with a locking screw groove corresponding to the locking rod 4. Support plates 5 are fixedly connected to the outer side walls at both ends of the hollow tube 2. A stop rod 6 is slidably inserted into the support plate 5. A plurality of stop grooves corresponding to the stop rod 6 are provided on the outer side wall of one side of the connecting rod 3 where the stop rod 6 is located. A limiting sleeve 7 is fixedly sleeved on the end of the stop rod 6 close to the connecting rod 3. Specifically speaking, screwing the locking rod 4 at one end of the connecting rod 3 into the locking groove on the positioning block 1 can achieve the assembly between the connecting mechanism and the positioning block 1. The position of the connecting rod 3 in the hollow tube 2 can be slid according to actual use requirements to adjust the length. After adjusting to the appropriate length, sliding the stop rod 6 on the support plate 5 into the corresponding stop groove of the connecting rod 3 can realize the position fixation of the connecting rod 3. The limiting sleeve 7 on the stop rod 6 can prevent the stop rod 6 from disengaging from the support plate 5.

[0018] In this embodiment, fixing nails 8 are fixedly connected to the bottoms of the four positioning blocks 1, which is convenient for positioning the positioning blocks 1; a limiting block 9 is fixedly connected to the end of the connecting rod 3 located inside the hollow tube 2 to prevent the connecting rod 3 from disengaging; a spring is sleeved on the stop rod 6. Both ends of the spring 10 are fixedly connected to the limiting sleeve 7 and the support plate 5 respectively, which is convenient for the stop rod 6 to rebound into the stop groove; a pull ring 11 is fixedly connected to the end of the stop rod 6 away from the limiting sleeve 7, which is convenient for pulling the stop rod 6.

[0019] Working principle: First, screwing the locking rod 4 at one end of the connecting rod 3 into the locking groove on the positioning block 1 can achieve the assembly between the connecting mechanism and the positioning block 1. The position of the connecting rod 3 in the hollow tube 2 can be slid according to actual use requirements to adjust the length. After adjusting to the appropriate length, sliding the stop rod 6 on the support plate 5 into the corresponding stop groove of the connecting rod 3 can realize the position fixation of the connecting rod 3. The limiting sleeve 7 on the stop rod 6 can prevent the stop rod 6 from disengaging from the support plate 5.
