Description

Technical Field

[0001] The utility model relates to the technical field of electric drills, in particular to an improved structure for high-speed and low-speed switching of electric tools. Background Art

[0002] An electric drill is a drilling tool that uses electricity as power. The working principle of an electric drill is that the motor rotor of an electromagnetic rotary or electromagnetic reciprocating small-capacity electric motor performs magnetic field cutting and work operation, and drives the operating device through the transmission mechanism, driving the gears to increase the power of the drill bit, thereby allowing the drill bit to scrape the surface of the object and penetrate the object better. During operation, in order to switch the drill bit, the electric drill needs to be improved.

[0003] Existing technologies, such as: CN215658006U, a high-low speed switching mechanism for an electric tool, separates the surrounding tube from the connecting column by rotating the fixed column, and drives the drill body downward by rotating the rotating rod downward. Through the principle of leverage, the drill body on the other side of the rotating column moves upward, so that the drill body on the other side is connected to the electric drill body, which is convenient for replacing the drill bit of the electric tool and convenient for people to disassemble and install. The replaced drill bit is always connected to the electric drill body to avoid loss, which is convenient for users to use.

[0004] However, the device still has certain shortcomings during use. When working, the device can only switch between two drill bits, which reduces practicality. Since the support column is fixed on the side of the handle of the electric drill body, it is not convenient to hold the handle during work and has certain limitations. Since the connecting block and the connecting block for switching are both located on the same rotating column, it is not convenient to install the drill bit and reduces work efficiency.
