Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fruit tree grafting, and in particular relates to an auxiliary device for planting and grafting apple trees. Background Art
[0002] A fruit tree grafting assistance device is a tool used to improve the efficiency and quality of fruit tree grafting, designed to help gardeners perform grafting operations more accurately and easily. The device typically includes a tool, a clamp, and an adjustment mechanism, enabling automated or semi-automated grafting operations, such as cutting the rhizome, adjusting the cutting angle, and applying appropriate pressure. The advent of this type of device significantly lowers the technical barriers to grafting, allowing even beginners to master grafting techniques quickly, thereby improving the survival rate and economic benefits of fruit trees. While existing fruit tree grafting assistance devices can assist users in grafting, they still have drawbacks. Most existing grafting assistance devices are designed for specific fruit tree varieties and are not widely applicable to a wide range of fruit trees, limiting their scope of application. A conventional approach is to use different grafting assistance tools for different fruit tree varieties. However, this approach requires users to master the use of multiple tools, requiring training for inexperienced users, raising the barrier to use. Therefore, a new structure is proposed to address these issues. Utility Model Content
