Abstract

The invention relates to the technical field of electric tools, in particular to a rechargeable electric screw driver. The rechargeable electric screw driver comprises a handle, a screw driver head and a shell, wherein the bottom of the handle is provided with a battery pack and a charger; the battery pack is positioned below the charger; the upper part of the handle is provided with a motor; the motor is connected with the screw driver head through a union joint; and the middle part of the handle is provided with a start switch. The rechargeable electric screw driver has the mandrel locking function; if the start switch is not pressed down, the mandrel is automatically locked; and at this time, even if the battery runs down, the screw driver head can be rotated to rotate the screw. Due to the adoption of high-performance motor without a carbon brush, the invention has excellent durability and does not need maintenance; due to the adoption of motor without a carbon brush, the invention does not discharge substances which affect electronic components; and even if the rechargeable electric screw driver is used continuously, the motor hardly emits heat.

Description

technical field [0001] The invention relates to the technical field of electric tools, in particular to a rechargeable electric screwdriver. Background technique [0002] At present, the rechargeable screwdriver in the prior art is equipped with a charging device, which can enable the rechargeable screwdriver to be used in places where there is no power supply or where the power cord cannot be reached, thereby expanding the use range of the electric screwdriver. But this rechargeable screwdriver can only work in a single electric mode, and when there is no alternating current and the battery pack has no electricity, it cannot normally function as a screwdriver. At the same time, the battery used in the existing rechargeable screwdriver has poor durability and requires frequent maintenance, which increases its maintenance cost. Moreover, due to the long working hours and abnormal heating of the motor, the screwdriver cannot work normally. Contents of the invention [0003]...
