Description

Screwdriver

Technical field

The utility model relates to a kind of instrument, specifically is meant a kind of screwdriver.

Background technology

Screwdriver is a kind of very common instrument.The most frequently used screwdriver such as the structure shown in the accompanying drawing 1 in the prior art, it comprises handle 001 and cutter head 002, and cutter head 002 is inserted in the handle 001, and cutter head 002 is common has two kinds of in-line and cross.Handle 001 generally is a column construction.In use there is following weak point in the screwdriver of this structure: because handle 001 is a column construction; The people can only rotate the application of force through finger rotation or wrist when holding handle 001 the turn of the screw, these two kinds of force mechanisms, and the strength of using can be very not big; Simultaneously these two kinds of force mechanisms when the application of force, lack one along screwdriver shaft to pressure; Screwdriver is vacillated now to the left, now to the right easily, and the easy like this cutter head 002 that makes deflects, thereby causes the screw stripped thread.

The utility model content

The technical problem that the utility model will solve is, provide a kind of when the turn of the screw the application of force more convenient, and be not easy to cause the screwdriver of stripped thread.

For solving the problems of the technologies described above; The technical scheme that the utility model provides is: a kind of screwdriver, and it comprises handle and cutter head, handle is installed in the top of cutter head; Handle is provided with left side swing handle and right side swing handle; The upper end of left side swing handle is rotationally connected through second pin and handle, and the upper end of right side swing handle is rotationally connected through first pin and handle, and first pin is positioned on the same horizontal plane with second pin.

After adopting said structure, the utlity model has following advantage: handle is provided with left side swing handle and right side swing handle.The user can open to the position vertical with handle respectively with the right side swing handle with the left side swing handle when the turn of the screw; Thumb props up the left side swing handle then, and nameless and little finger of toe props up the right side swing handle, and can screw be turned with the limit rotation; Like this through left side swing handle vertical and of the guiding of right side swing handle to pointing with handle; Be not easy deflection during user's application of force, left side swing handle and right side swing handle have increased the turning moment of cutter head simultaneously, and natural the turn of the screw is more convenient for.

As improvement, described handle is provided with two and is respectively applied for the swing handle groove that holds left side swing handle and right side swing handle.This structure can make left side swing handle and right side swing handle place in the swing handle groove, has dwindled the volume of handle, and the posture of custom was used screwdriver before the user can also adopt simultaneously.

As further improvement, the main body of the handle of the lower end of described swing handle groove is provided with and is used for groove that left side swing handle or right side swing handle are broken off with the fingers and thumb out in the swing handle groove.The design of groove has further facilitated the taking-up of swing handle.
