Since the buckle 305 includes an elastic arc-shaped spring piece 3051 and a retractable tension spring 3052, the buckle 305 will automatically adjust its inner diameter according to the thickness of the corn stalks in different growth periods when the corn grows, and will not limit the growth space of the corn like the bundling method. It can avoid affecting the growth of corn or even causing damage to the corn plant due to insufficient growth space, thereby ensuring corn yield. In addition, the method of using the buckle 305 to buckle the lower side of the trumpet mouth of the corn plant for anti-lodging support is simpler to operate than the traditional method of bundling the corn stalks with fixed objects for anti-lodging support, reduces labor intensity, and improves operating efficiency.

[0035] like Figure 1-6 As shown, the specific working principle of the utility model is:

[0036] When the present invention is working, the lower side of the square rod 1 is provided with a uniformly arranged number of support frames 2 and stabilizing members 3.

In this embodiment, the length of the square rod 1 is 5 meters, and 3 support frames 2 are evenly arranged on the lower side of the square rod 1. 3 stabilizing members 3 are set between adjacent support frames 2. When working, first step on the pedal 2041 with your foot to insert the conical tip end of the ground rod 204 into the soil so that the distance between the square rod 1 and the ground is between 1 and 1.4 meters, and then install the telescopic support rod 2 03, thereby stabilizing the utility model on the ground; after sliding the slider 301 to the position corresponding to the corn plant that needs to be supported against lodging, use a matching screw to screw into the two threaded holes that pass through the bottom of the slider 301, so that the top of the screw is pressed against the lower side of the square rod 1, thereby fixing the stabilizing member 3. At this time, use the buckle 305 to buckle the bottom of the trumpet mouth of the corn plant that needs to be supported against lodging in turn, and use the hook of one of the tension springs 3052 to buckle it with the round hole at one end of the arc-shaped spring piece 3051 to complete the corn anti-lodging support work.
