Abstract

The utility model provides a light-duty right angle electric screwdriver for solve the light-duty electric screwdriver of current penholder formula when using lift arm, main part and point between skid, hold the pen type and hold the method and do not operate scheduling problem well. The screwdriver consists of a screwdriver head, a screwdriver head seat, a 90-degree reduction gear system, a switch button, a motor, a control circuit board, a battery and a plastic shell. The structure that the tool bit is vertical to the tool handle enables the small arm to be horizontally placed on the working plane to work, so that the working fatigue can be effectively reduced; the whole handle becomes a force arm, so that the moment is increased, and the slipping problem is avoided; the pen-holding method is changed into a palm-holding method, so that the operation is easier.

Description

Light right-angle electric screwdriver

Technical Field

The small-sized gear motor drives the cutter head to rotate to do work.

Background

The common light electric screwdriver is of a pen holder type, the arm needs to be lifted for working, the arm of force is very small and is the radius of the pen holder, the main body and fingers are easy to slip when the screw is screwed down, in addition, the diameter of a handle of the screwdriver is large by a pen-holding method, the screwdriver can be unstable and is not easy to operate, and the left side of the centering finger is greatly pressed.

Background

Disclosure of Invention

To the above problem, the utility model provides a this problem is solved to tool bit and handle of a knife vertically light-duty right angle electric screwdriver.

The utility model discloses a light-duty right angle electric screwdriver comprises tool bit, tool bit seat, 90 reduction gear system, shift knob, motor, control circuit board, battery, plastic casing.

The structure that the tool bit is vertical to the tool shank can enable the small arm to be horizontally placed on the working plane to work, and the working fatigue can be effectively reduced.

The structure that the tool bit is vertical to the tool shank enables the whole handle to become a force arm, so that the moment is increased, and the slipping problem is avoided.

FIG. 1 is a front view of the present invention

In the figure 1: 90 ° reduction gear system 2: the tool bit seat 3: the cutter head 4: a motor 5: switch key 6: the control circuit board 7: battery 8: a plastic housing.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, electric energy is generated by a battery 7 and is input to a control circuit board 6, the circuit board can generate two currents with opposite polarities, one of the currents is output to a motor 4 through a switch button 5, the electric energy is converted into kinetic energy after being output to the motor 4, the kinetic energy is input to a 90-degree reduction gear system 1 through a rotating shaft, the rotating shaft rotates 90 degrees in the 90-degree reduction gear system 1, the rotating speed is reduced and the power is increased, then the 90-degree reduction gear system 1 outputs the power to a tool bit seat 2, and the tool bit 3 is installed on the tool bit seat 2 and can obtain the power to do work outwards.

The above functional components are all mounted on the plastic housing 8; the battery 7 is connected with the control circuit board 6 through a lead; the switch key 5 is connected with the control circuit board 6 through a wire; the motor 4 is connected with the switch key 5 through a wire; the motor 4 is connected with the 90-degree reduction gear system 1 through a rotating shaft; the 90-degree reduction gear system 1 is connected with the cutter head seat 2 through a rotating shaft. The tool bit seat 2 is connected with the tool bit 3 through a hexagonal groove and a magnetic suction mode.

The switch button 5 is mounted on the side of the plastic housing 8.
