An adjustment mechanism 8 is provided on the support 1, and a positioning mechanism 9 is provided on the positioning seats 7.

[0024] Please see Figure 1 , Figure 2 , Figure 3 The adjustment mechanism 8 includes a slider 81, which is slidably sleeved inside the bracket 1. A slide rod 82 is fixedly connected to the outside of the slider 81, and the slide rod 82 is slidably connected to the bracket 1. A spring 83 is provided on the outside of the slide rod 82. One end of the spring 83 is fixedly connected to the bracket 1, and the other end of the spring 83 is fixedly connected to the connecting strip 84. By designing the spring 83, the force of the spring 83 can be applied to the connecting strip 84. A connecting strip 84 is fixedly connected to the outside of the slide rod 82, and a wheel frame 85 is fixedly connected to the outside of the connecting strip 84. A roller 86 is hinged to the inside of the wheel frame 85, and the roller 86 contacts the protective net 6. By designing the adjustment mechanism 8, the height of the device can be easily adjusted.

[0025] Please see Figure 1 , Figure 4 , Figure 5 The positioning mechanism 9 includes a screw 91. The screw 91 is rotatably connected to the inside of the positioning cone 10 via a bearing. A handle 92 is fixedly connected to the top of the screw 91. A pressure block 93 is threadedly connected to the outside of the screw 91. The pressure block 93 is slidably connected to the positioning cone 10. A guide block 94 is fixedly connected to the outside of the pressure block 93. The guide block 94 is slidably connected to the positioning cone 10. A guide groove 95 is provided inside the positioning cone 10. The guide block 94 is slidably connected inside the guide groove 95. By designing the guide groove 95, the guide block 94 can slide inside the guide groove 95. An insert block 96 is in contact with the bottom of the pressure block 93. The insert block 96 is slidably connected to the positioning cone 10. A connecting block 97 is slidably sleeved inside the insert block 96. The connecting block 97 is fixedly connected to the positioning cone 10. By designing the connecting block 97, the movement of the insert block 96 can be guided. By designing the positioning mechanism 9, the positioning stability of the device can be improved.

[0026] The specific implementation process of this utility model is as follows: In use, the positioning cone 10 is first inserted into the ground. The positioning cone 10 can position the overall structure of the positioning seat 7, the bracket 1 and the connecting frame 3. Then, the handle 92 is rotated, and the handle 92 drives the screw 91 to rotate. Through the threaded connection between the screw 91 and the pressure block 93, the pressure block 93 makes threaded movement. The pressure block 93 drives the guide block 94 to slide along the guide groove 95. The pressure block 93 will move down along the inclined surface of the insertion block 96. The pressure block 93 will press down on the insertion block 96. The insertion block 96 will slide along the connecting block 97, so that the insertion block 96 extends out of the positioning cone 10 and is inserted into the ground, which can improve the positioning stability of the positioning cone 10.

[0027] The rice seedlings can be protected from wind by the support frame 1, connecting frame 3, and protective net 6. When the height of the device needs to be adjusted, first turn the limiting screw 5 to remove it from the limiting groove 4, then move the connecting frame 3. The connecting frame 3 drives the connecting rod 2 to slide along the support frame 1. Then, screw the limiting screw 5 into the limiting groove 4 at another position. During the upward movement of the connecting frame 3, the connecting frame 3 stretches the protective net 6. The protective net 6 will push the roller 86 to move horizontally. The roller 86 will drive the wheel frame 85 and the connecting bar 84 to move horizontally. The connecting bar 84 will drive the slide bar 82 and the slider 81 to move. The connecting bar 84 will squeeze the spring 83. Under the elastic action of the spring 83, it will give the connecting bar 84 a reaction force, which can make the roller 86 press against the protective net 6. This ensures that the protective net 6 can always be kept taut under the support of the roller 86 when the height of the device is adjusted, thus improving the wind protection effect.
