Height adjustment components are provided on both sides of the barrier net 101. Each height adjustment component includes a support column 102 and a lifting column 103. The lifting column 103 is slidably installed inside the support column 102. A connecting component is provided on one side of the height adjustment component. A fixing plate 105 is fixedly installed inside the support column 102. A threaded rod 104 is rotatably installed inside the fixing plate 105 and threadedly installed inside the lifting column 103. A rotating shaft 106 is rotatably installed inside the barrier net 101. A second bevel gear 108 is fixedly installed on the outer surface of the rotating shaft 106. A first bevel gear 107 is fixedly installed at one end of the threaded rod 104, and the first bevel gear 107 meshes with the second bevel gear 108. A knob 10 is fixedly installed at one end of the rotating shaft 106. 9. The connecting assembly includes a first connecting block 201 and a first slot 202. The first connecting block 201 is fixedly installed on the outer surface of one of the support columns 102, and the first slot 202 is fixedly installed on the outer surface of the other support column 102. A second slot 205 is provided on one side of the first slot 202. A second connecting block 203 is installed inside the first connecting block 201. A spring 204 is fixedly connected to one end of the second connecting block 203, and the other end of the spring 204 is fixedly connected to the inside of the first connecting block 201. One side of the second connecting block 203 is set as an arc surface. A handle 110 is fixedly installed on the other side of both support columns 102. A metal ball 113 is fixedly installed on the top of both lifting columns 103. A support plate 111 is fixedly installed on the bottom of both support columns 102. An installation plug 112 is fixedly installed on the lower surface of both support plates 111.

[0025] In this embodiment, support plates 111 are fixedly installed at the bottom of both support columns 102. Multiple mounting inserts 112 are installed on the lower surface of the support plates 111. The device is fixed by inserting the mounting inserts 112 into the ground. Metal balls 113 are installed at the top of both lifting columns 103. These metal balls effectively prevent birds and insects from landing on the device. When disassembling and transferring the device, two knobs 109 are manually rotated. The knobs 109 are fixedly connected to the rotating shaft 106. Rotation drives the second bevel gear 108 on the outer surface of the rotating shaft 106 to rotate. At this time, the fixing plate 105 is fixedly installed inside the support column 102, and the threaded rod 104 is rotatably installed inside the fixing plate 105. A first bevel gear 107 is installed at one end of the threaded rod 104. Therefore, the rotation of the threaded rod 104 is achieved through the meshing connection between the first bevel gear 107 and the second bevel gear 108. The lifting column 103 has a rectangular cross-section. The second connecting block 203 is slidably installed inside the support column 102. At this time, the threaded rod 104 is threaded inside the lifting column 103. The lifting column 103 slides inside the support column 102 by rotating the threaded rod 104, thereby adjusting the height of the device. Then, the two support columns 102 are aligned, and the first connecting block 201 is snapped into the first slot 202. One side of the second connecting block 203 is set as an arc surface and is slidably installed inside the first connecting block 201. At this time, by pressing, the second connecting block 203 is pressed into the first connecting block 201. A second slot 205 is provided on one side of the first slot 202. When the second connecting block 203 moves to the second slot 205, a spring 204 is connected between the second connecting block 203 and the first connecting block 201. Then, the second connecting block 203 is pushed down by the spring 204 and pushed into the second slot 205 to achieve snapping, thereby fixing the two support columns 102.

[0026] Working principle: Support plates 111 are fixedly installed at the bottom of both support columns 102. Multiple mounting plugs 112 are installed on the lower surface of the support plates 111. The device is fixed by inserting the mounting plugs 112 into the ground. When it is necessary to disassemble and transfer the device, two knobs 109 are manually rotated. The knobs 109 are fixedly connected to the rotating shaft 106. The rotation drives the second bevel gear 108 on the outer surface of the rotating shaft 106 to rotate. At this time, the fixing plate 105 is fixedly installed inside the support column 102, and the threaded rod 104 is rotatably installed inside the fixing plate 105. A first bevel gear 107 is installed at one end of the threaded rod 104. Therefore, the rotation of the threaded rod 104 can be realized through the meshing connection between the first bevel gear 107 and the second bevel gear 108. The lifting column 103 is rectangular in cross-section and is slidably installed inside the support column 102. At this time, the threaded rod 104 is screwed... The threaded rod 104 is installed inside the lifting column 103, and the lifting column 103 slides inside the support column 102 by rotating the threaded rod 104, thereby adjusting the height of the device. Then, the two support columns 102 are aligned, and the first connecting block 201 is snapped into the first slot 202. One side of the second connecting block 203 is set as an arc surface and is slidably installed in the first connecting block 201. At this time, by pressing, the second connecting block 203 is pressed into the first connecting block 201. A second slot 205 is provided on one side of the first slot 202. When the second connecting block 203 moves to the second slot 205, a spring 204 is connected between the second connecting block 203 and the first connecting block 201. Then, under the push of the spring 204, the second connecting block 203 is pushed into the second slot 205 to achieve snapping, thereby fixing the two support columns 102.
