[0002] In the field of screwdriver technology, with the increasing demands of industrial manufacturing and daily life, screwdrivers, as key tools for tightening and loosening screws, are constantly being innovated and improved in terms of function and design. Traditional screwdrivers mainly rely on manual operation, requiring users to manually select, align, and tighten screws. This method may be acceptable for a single job, but when faced with a large number of screw tightening tasks, such as home renovations, automobile manufacturing, or electronic equipment assembly, it becomes inefficient and labor-intensive. Therefore, highly automated tools such as electric screwdrivers and pneumatic screwdrivers have gradually emerged on the market. These tools, driven by electricity or pneumatic pressure, significantly improve the efficiency and accuracy of screw tightening.

[0003] Although electric or pneumatic screwdrivers improve work efficiency to some extent, they still have some shortcomings, especially in the automatic loading and precise delivery of screws. Existing automated screwdrivers often require manual loading of screws before each job, which not only increases the complexity of operation but also limits the continuity of work, resulting in poor performance of the device. Therefore, it is necessary for workers to improve it. Utility Model Content
