Description

Novel combined screwdriver

Technical field

The present invention relates to a kind of instrument of the turn of the screw, particularly relate to a kind of novel combined screwdriver.

Background technology

In industrial and daily life, use screwdrivers (also claiming screwdriver) at present in a large number.Screwdriver commonly used is in-line or cross.Screwdriver commonly used is had an effect with handle, and with big strength or with to the first-class tighten the screws of hardwood, bolt the time, screwdriver is difficult to have an effect at need.At the turn of the screw, bolt initial stage, screw, bolt can be dilapidated especially, and sometimes that notch on screw, the bolt head is stubborn bad, driver bit can skid off screw, bolt head sometimes.When skidding off screw, bolt head, driver bit can injure hand or other parts in addition.

Summary of the invention

The purpose of this invention is to provide a kind of novel combined screwdriver, safety labor-saving when using the turn of the screw of this screwdriver, screw can be not dilapidated, be difficult for to twist notch on the bad screw terminal, and driver bit can not skid off on the screw terminal notch and injure hand or other parts in addition.This screwdriver also has easy to carry and a cutter two purposes.

Technical scheme of the present invention is: a kind of novel combined screwdriver,

Its screwdriver rod upper end tight fit plug-in mounting is gone in the handle of a knife lower shell of screwdriver handle bottom, and the screwdriver rod lower end is the edge of a knife of the turn of the screw.

In the handle of a knife lower shell in the middle of its screwdriver handle bottom magnet piece is housed.

Its screwdriver rod lower end is equipped with Yi the tight screw function of Ju You Clip and can be moved up and down the tight Luo Si of De Clip Clip along screwdriver rod.

The end that its rotation adds the arm of force is for adding arm of force inner ring, and the screwdriver handle lower end is the afterburning arm of handle of a knife, rotation add the arm of force add arm of force inner ring can the tight fit movable set on the afterburning arm of the handle of a knife of screwdriver handle.

Be provided with in the middle of its screwdriver handle top and can deposit handle of a knife upper shell A and the handle of a knife upper shell B that rotation adds the arm of force and screwdriver rod.

But its screwdriver handle upper end is provided with the end cap of spinning on the screwdriver handle upper end.

During use screwdriver rod is inserted in the handle of a knife lower shell, coping screw knife bar and handle of a knife lower shell are hexagon or tetragonal structure tight fit and install, thereby rotary handle and/or rotation add the arm of force and all can tighten or unscrew screw effectively.Because of in the handle of a knife lower shell magnet piece being housed, need not can not deviate from the handle of a knife lower shell by big external force screwdriver rod again.Screw can be not dilapidated when making the turn of the screw of this screwdriver behind dress Clip tight spiral shell silk Clip on screwdriver rod, is difficult for twisting notch on the bad screw terminal, and driver bit can not skid off on the screw terminal notch and injure hand or other parts in addition.Dress rotation adds behind the arm of force the turn of the screw safety labor-saving more.Can to make screwdriver reach a cutter dual-purpose for standby another screwdriver rod in handle of a knife.Rotation adds the arm of force and standby screwdriver rod and packs that this screwdriver to be carried in the handle of a knife convenient into.

Advantage of the present invention has provided a kind of novel combined screwdriver, and safety labor-saving when using the turn of the screw of this screwdriver, screw can be not dilapidated, be difficult for to twist notch on the bad screw terminal, and driver bit can not skid off on the screw terminal notch and injure hand or other parts in addition.This screwdriver also has easy to carry and a cutter two purposes.
