Description

A kind of laborsaving screwdriver

Affiliated technical field

The utility model relates to a kind of screwdriver, especially a kind of laborsaving screwdriver.

Background technology

Screwdriver is a kind of common tool, and its structure is made up of with the handle that becomes the stretched shape knife bar, and user's gripping handle rotation application of force can tighten or loosen screw.The shank of general screwdriver is provided with increases longitudinal fluting or the raised line that grips torsion, applies the operation of torsion greatly for need, and the available friction torsion of this structure is limited, and the operator firmly often causes palm injured by force.In the prior art, the design that directly handle portion is designed to " T " font is arranged, but its inconvenience carries, also the screwdriver not as the stretched shape is convenient smoothly during use.

The utility model content

Problem to be solved in the utility model is to provide a kind of laborsaving screwdriver, and it is simple in structure, and production cost is low, and is easy to use.

The utility model adopts following technical scheme: comprise knife bar, handle, the handle body sidewall of described handle is provided with through hole, and the Kong Xiangyu handle body bearing of trend of described through hole is perpendicular, and the aperture of described through hole and the diameter of knife bar are complementary.Generally use with the normal screws cutter; When the big torsion of need, the knife bar of the screwdriver of another suitable size to be inserted in the through hole, the handle portion application of force that grips two screwdrivers gets final product.

A kind of improvement is that the hole wall of described through hole is provided with metal lining.This hole wall is more durable.

Employing the utlity model has following advantage:

1, its improvement part is simple in structure, and adding only needs newly on the screw driver handle of existing structure to bore the through hole that a knife bar of being convenient to another screwdriver passes and get final product man-hour, and its processing is very simple and convenient, increases cost hardly, is convenient to popularization;

2, its rapid operation is convenient, and the situation (as turn on the corrosion screw or be screwed into screw etc. on wood substrate) that is particularly suited for need applying than big torsion is manipulated;

3, compare with " T " font handle, it has kept the contour structures of original screwdriver, has portable advantage.

Marginal data

Below in conjunction with embodiment the utility model is described in further detail.

Fig. 1 is a kind of example structure schematic diagram of the utility model.

Fig. 2 is a user mode schematic diagram of the present utility model.

The specific embodiment

As shown in Figure 1 and Figure 2, a kind of embodiment of the utility model comprises knife bar 1, handle 2, and the handle body sidewall of described handle 2 is provided with through hole 3, and the Kong Xiangyu handle body bearing of trend of described through hole 3 is perpendicular, and the diameter of the aperture of described through hole 3 and knife bar 1 is complementary.Its principle is: it uses with the normal screws cutter generally speaking; When the big torsion of need, the knife bar of the screwdriver of another suitable size to be inserted in the through hole 3, handle 2 application of forces that grip two screwdrivers simultaneously can reach laborsaving purpose.

For making hole wall durable, the hole wall of described through hole 3 can sheathed metal lining.All falling within the protection domain of other and the similar mapped structure of the utility model.

Claims

1, a kind of laborsaving screwdriver comprises knife bar, handle, it is characterized in that: the handle body sidewall of described handle is provided with through hole, and the Kong Xiangyu handle body bearing of trend of described through hole is perpendicular, and the aperture of described through hole and the diameter of knife bar are complementary.
