Screwdriver is that people are used for the fastenings necessary tool.Existing screwdriver is divided into single pole screwdriver and many bars screwdriver two big classes usually according to the fixed form of its knife bar and handle.The knife bar of single pole screwdriver is fixed on the handle, and knife bar can not change.This screwdriver arm of force is longer, and is comparatively laborsaving during use, but because function singleness, the scope of application is narrower, thus carrying out dissimilar securing members when fastening, must dispose usually many screwdriver of different model with standby.The knife bar of many bars screwdriver and handle generally are split-type structural, and its knife bar can be changed as required.But this screwdriver must dispose instrument cases or a kit bag of a special use usually, in order to hold knife bar and handle; Secondly, fixedly reaching of its knife bar and handle in use by screwing screw thread, therefore, handling speed is slower.

The utility model is intended to overcome above-mentioned shortcoming, provides a kind of novel structure, volume little, installs, novel many bars screwdriver easy to use.

The purpose of this utility model is achieved like this:

The utility model is made of handle and the dissimilar screwdriver rod of the six roots of sensation, is provided with six knife bar holes in handle, and the dissimilar screwdriver rod of the six roots of sensation is hidden in six knife bar holes of handle dexterously; Outside in handle knife bar hole is equipped with protecgulum, to prevent that knife bar skids off in the knife bar hole.During use, realize the turnover of whole knife bar by the rotation calibration of handle protecgulum, after treating that knife bar takes out, be inserted into the knife bar cover that is positioned at handle center again, and by the rotation protecgulum make its stationary positioned, like this, can very constitute a kind of screwdriver that can finish multiple fastening function easily.

The utility model through after the above-mentioned design compared with prior art, has the following advantages:

1, simple in structure, volume is little, carry, easy to use;

2, multiple functional, one can finish all working of various screwdrivers to many bars screwdriver.

Specific embodiments of the present utility model is as shown in drawings:
