[0002] Blueberry planting is increasingly popular, and the pruning of blueberry by planting personnel is crucial to the yield and quality of blueberry. In the existing technology, the traditional pruning method usually uses household scissors to prune branches. This method not only has low work efficiency, but also consumes a lot of manpower and time. In addition, the operator needs to use a lot of force continuously, which can easily cause hand muscle overfatigue and strain. Long-term repetitive work of high intensity not only affects work efficiency, but also poses a potential threat to the user's health, seriously affecting the overall work effect.

[0003] Secondly, although some special tools for blueberry branch pruning appear in the prior art, these pruners have obvious design defects. The main problem is that the blade part and the handle of the pruner are usually designed integrally. After long-term use, the blade part will become dull, losing its original sharpness. Due to the limitation of the overall structure, the blade part cannot be replaced individually when it becomes dull, and the entire pruner must be replaced. This design greatly increases the use and maintenance cost of the equipment, causing unnecessary waste of resources.

[0004] In addition, although some improved models of pruning equipment introduce a quick disassembly mechanism to try to solve the problem of blade replacement, these designs are too simplified in structure, which brings new problems. Although the quick disassembly function of the blade part is achieved, the installation process is still complicated, which increases the operation difficulty of the workers and can affect the use effect of the equipment due to improper installation. This seemingly improved but actually complicated design not only does not fundamentally solve the problem, but also affects the work efficiency, greatly reducing the practicality of the equipment.
