Description

Technical Field

[0001] The invention relates to the field of bit switchers, and in particular to a portable bit switcher for an electric screwdriver. Background Art

[0002] An electric screwdriver, also known as an electric screwdriver or electric screwdriver, is an electric tool that uses the electricity at the front end to drive the electric screwdriver bit or drill bit to tighten and loosen screws and nuts.

[0003] However, existing electric screwdrivers are used with screwdriver bits or drill bits of different shapes and sizes according to the construction situation. This will cause the screwdriver bits or drill bits of various models to be easily lost or mixed up if they are not stored in an orderly manner, causing certain inconveniences to users.

[0004] Therefore, in order to solve the problem that the electric screwdriver bits or drill bits of the electric screwdriver are easily lost or mixed up if they are not stored in an orderly manner, a portable bit switcher for an electric screwdriver can be designed. Summary of the invention

[0005] To overcome the problem that the electric screwdriver bits or drill bits of electric screwdrivers can easily be lost or mixed up if they are not stored in an orderly manner.
