Description
Technical Field
[0001] This utility model relates to the field of power tool technology, and in particular to a portable electric screwdriver. Background Technology
[0002] As a common tool in mechanical assembly and repair, the portability, operational flexibility, and functional integration of electric screwdrivers directly impact the user experience. Traditional electric screwdrivers often employ a one-piece design, with the handle fixedly connected to the main body, resulting in a large overall size that is difficult to store in compact spaces (such as toolbox compartments or the interior of small devices). Furthermore, in scenarios requiring precise operation (such as screw assembly inside electronic devices), an excessively long handle may obstruct the operating view or increase the risk of accidental activation, forcing users to work in non-standard postures, which can easily lead to hand fatigue or even injury with prolonged use. In addition, the screwdriver bits of traditional electric screwdrivers need to be stored separately, making the replacement and storage of the bits extremely inconvenient.
[0003] Therefore, given the shortcomings of existing technologies, it is necessary to design a portable electric screwdriver to solve the above problems.
[0004] It should be noted that the above introduction to the technical background is only for the purpose of providing a clear and complete explanation of the technical solution of this utility model and facilitating the understanding of those skilled in the art.
