Poor growth due to rain and water accumulation will not occur, and it is not easy to get various viral diseases. In the process of pepper breeding, a plant fixing device is needed to fix the stem and root system of the pepper to prevent the pepper seedlings from tilting due to the soil being too soft. However, the existing plant fixing devices for pepper breeding have some shortcomings, such as: Application number: CN202220918133.7 A plant fixing device for pepper breeding, the device improves the stability of the device by setting a counterweight component at the bottom, inserts the piercing steel nail into the specified position during operation, and is convenient to fix the device on the soil around the plant when used in conjunction, and the device can be rotated arbitrarily, the component used to fix the plant can be extended and retracted, and the distance is convenient to adjust, and three groups of fixing holes with different inner diameters are set to facilitate the fixing of different plants. It is more flexible and convenient to use than before, but in actual use, it is difficult for the device to fix the root system of the pepper seedlings and the soil to which the root system is attached, which may cause the root system to drive the plant to tilt or collapse when the device is fixing the stem of the pepper seedlings, thereby reducing the stability of the device in fixing the pepper seedlings; Therefore, we propose a plant fixing device for pepper breeding and a method of using the same to solve the above-mentioned problems. Summary of the invention

[0019] As a preferred technical solution of the present invention, when the supporting mechanism supports the stem of the pepper seedling, the supporting ring will cover the stem of the pepper seedling, and the supporting clamp will fit with the stem of the pepper seedling under the push of the spring rod, so that the supporting mechanism can support and fix the stem of the pepper seedling.

[0021] The adoption of the above technical solution can make it more convenient for users to raise different pepper seedlings, thereby increasing the convenience of the equipment in classification operations during seedling raising.

[0022] Compared with the prior art, the beneficial effects of the present invention are as follows: the second sprocket and the second rotating shaft are driven to rotate by the driving motor, so that the fixing mechanism can be lifted and lowered inside the placement cavity, so that the fixing mechanism fixes the soil and the root system of the pepper seedling inside the placement cavity, and cooperates with the supporting mechanism to fix the plant part and the root system part of the pepper seedling at the same time, thereby increasing the stability of the device when fixing the pepper seedling; Furthermore, by providing two sets of ratchet groups, the driving motor can be more convenient when driving the first rotating shaft and the second rotating shaft, thereby increasing the maneuverability of the device during operation, making it more convenient for the user to adjust the height of the supporting mechanism or the fixing mechanism; Furthermore, by connecting the support ring with the support clamp through a spring rod, the support ring can adjust the position of the support clamp through the spring rod, so that the support clamp can be more stable when it fits with the plant stem of the pepper seedling to support and fix it.
