Embodiment Construction

[0021] The technical solution of the present invention will be described in detail below through specific examples.

[0022] Such as Figure 1-3 As shown, the miniature electric screwdriver includes a housing 1 in which a battery 3 and a drive mechanism 4 driven by the battery are installed. The drive mechanism 4 includes a motor and a transmission. An output shaft 2 on which a bit 20 is installed is connected to the driving mechanism 4 .

[0023] The housing 1 is in the shape of a grippable box as a whole, that is, the shape of the housing 1 is approximately the size of a palm, the output shaft 2 protrudes downward from the bottom of the housing, and the top of the housing is provided with a curved surface for corresponding to the palm. When the grip portion 10 is in use, the line where the axis of the output shaft 2 is located passes through the user's palm. The output shaft 2 is inclined forward, and the angle a between the axis of the output shaft and the bottom surface ...

Abstract

The invention relates to an electric tool, in particular to a mini electric screwdriver which comprises a shell. A battery and a driving mechanism driven by the battery are installed in the shell. Anoutput shaft used for installation of a screwdriver head is connected to the driving mechanism. The shell is in a box shape capable of being operated in a handheld mode. The output shaft stretches outof the bottom face of the shell downwards. The top of the shell is provided with a handheld portion in a curved shape corresponding to the palm of a user. The box-shaped shell capable of being held by the palm is adopted and combined with the output shaft stretching out downward; when the mini electric screwdriver is in use, the axis of the screwdriver head passes through the palm of the user, force can be directly applied in the axial direction of the output shaft, and flexible operation and more precise control can be achieved more conveniently; and the mini electric screwdriver is applicable to installation and removal of screws in small and medium electronic products.
