Abstract

The utility model discloses a battery charging electric drill comprising a battery pack, a drill chuck, a gear box and a generator, wherein the gear box and the generator are connected with the drill chuck and positioned inside the body case. The utility model is characterized in that battery pack is connected with the lower of the body case via an electrical source connector which is composed of wire, electrical source connection component positioned on both end of the wire, and an engine connector. The utility model has the advantages of that the heavy battery pack is demountable to the engine and can be put in a bag, the electrical source is connected with engine via the connector, compared with the existing technology the electric drill is movable in a larger area, more convenient to operate, capable of doing some work which the existing electric drill is not capable of.

Description

A kind of Charge)

Technical field

The utility model relates to electric tool, particularly a kind of DC charging electric portable drill that has power brick.

Background technology

Various types of DC charging electric drills that have power brick are arranged in the prior art, but because of the power brick volume is big, weight heavier cause operating dumb, mobile range is little, the operating space is restricted, be not suitable for using in many instances, for example work high above the ground, the place that usage space is narrow and small etc., thereby application is restricted.For example, the patent No. is the disclosed a kind of storable Charge) of the Chinese patent of CN99254860, it is made up of parts such as commutation button, switch, power brick, torque adjusting device, actuating unit are installed in the forward and backward housing, described actuating unit is that motor and gear-box are fixed on the bonnet, the output shaft of gear-box is connected with the main shaft of band transposition gear, constitutes by the engagement of the output gear on transposition gear and the collet axis.This electric drill power brick volume is big, weight is heavier, and it is very inconvenient to operate.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of mobile range big, easy to operate electric drill.

The purpose of this utility model can adopt following measure to reach:

A kind of Charge), comprise power brick, drill chuck, the gearbox that is connected with drill chuck and motor, described gearbox and motor are installed in the casing, it is characterized in that: described power brick is connected to the bottom of casing by power connector, and described power connector comprises lead and is positioned at the battery connector and the machine connector at lead two ends.

The purpose of this utility model can also adopt following measure to reach:

Described battery connector comprises at the bottom of the battery connector and battery connector lid, at the bottom of the battery connector battery contact piece support is installed, and battery contact piece is contained on the battery contact piece support; Described machine connector comprises at the bottom of the machine connector and machine connector lid, at the bottom of the machine connector machine contact chip support is installed, and the machine contact chip is contained on the machine contact chip support.

Because the utility model has been taked above-mentioned technical measures, it compared with prior art, heavier power brick can be separated with machine, power brick can be placed on and hang between waist in the carry bag, power brick is connected with machine by connector, have advantages such as mobile range is big, easy to operate, can finish some particular job that existing D.C. electric drill can't be finished, thereby the scope of application is wider.
