Description

A kind of laborsaving multifunctional screw driver

Technical field

The utility model relates to screwdriver technical field, relates in particular to a kind of laborsaving multifunctional screw driver.

Background technology

Screwdriver is for twisting screw to compel its a kind of specific purpose tool in place, conventionally there is a thin sphenocephaly, can insert in the line of rabbet joint or recess of screw cap, but not of uniform size the causing in the line of rabbet joint of screw cap or recess, staff need to carry multiple different sizes or difform driver bit like this, thereby the work of carrying of the instrument of giving has brought trouble, the handle of at present common screwdriver mostly is cylindrical or oval, in the time that needs are twisted power more greatly, using can be more painstaking, in addition, because screwdriver is the professional tool of tightening or unscrew screw of specialty, also just more single in function.

Summary of the invention

The purpose of this utility model is to provide a kind of laborsaving multifunctional screw driver, and it has the handle of increase and twists the feature of power, screwdriver several functions.

For achieving the above object, the utility model adopts following technical proposals:

A kind of laborsaving multifunctional screw driver, comprise handle, cutter head bar, described cutter head bar rear portion is provided with tumbler, tumbler embeds in handle front end, described handle is trapezoidal, the described handle lower left corner and the lower right corner all offer rotation through hole, in the rotation through hole in the described handle lower left corner and the lower right corner, be equipped with Double-ended nut, described Double-ended nut two ends are socketed with rotary handle, described rotary handle comprises handle upper plate, handle lower plate, described handle upper plate and handle lower plate two ends are locked by Double-ended nut, on the Double-ended nut body of rod of described rotary handle bottom, be hinged with the rotatable inner hexagon spanner of some different models, between described each inner hexagon spanner, be provided with packing ring.

Wherein, described handle upper plate and handle lower plate outer surface are equipped with some anti-slip veins.

Wherein, in the middle of described handle rear portion, offer positioning baffle, described positioning baffle is V-type.

Wherein, described rotary handle can be to 0 ~ 90 ° of inner rotary

Wherein, the rear and front end of described handle upper plate and handle lower plate offers trepanning, and described trepanning is counter sink.

The utility model beneficial effect: the utility model comprises handle, cutter head bar, described cutter head bar rear portion is provided with tumbler, tumbler embeds in handle front end, described handle is trapezoidal, the described handle lower left corner and the lower right corner all offer rotation through hole, in the rotation through hole in the described handle lower left corner and the lower right corner, be equipped with Double-ended nut, described Double-ended nut two ends are socketed with rotary handle, described rotary handle comprises handle upper plate, handle lower plate, described handle upper plate and handle lower plate two ends are locked by Double-ended nut, on the Double-ended nut body of rod of described rotary handle bottom, be hinged with the rotatable inner hexagon spanner of some different models, between described each inner hexagon spanner, be provided with packing ring, the utility model is rational in infrastructure, by all establishing rotating rotary handle in handle rear end left and right portion, and in rotary handle, establish turnover inner hexagon spanner, thereby increasing when screw driver handle is twisted power makes screwdriver have several functions.
