Description

Multifunctional screw driver

Technical field the utility model relates to a kind of instrument, especially a kind of multifunctional screw driver.

Background technology is well-known, screwdriver is one of frequent instrument that uses of people, present screwdriver is owing to defective on the 26S Proteasome Structure and Function, use very inconvenience, for example: twist a word, cross, screw that hexagonal is different sometimes, this just needs several different screwdrivers, and is very inconvenient; The screw that utilizes screwdriver to back out is very little, loses easily, seeks very inconvenient; The screw that has because get rusty or install very tight, present screwdriver is held mode and is twisted and waste time and energy.

The summary of the invention the purpose of this utility model provides a kind of multifunctional screw driver, is used to solve above-mentioned said deficiency.

For achieving the above object, the utility model multifunctional screw driver, comprise handle, knife bar and cutter head, the affixed knife bar in the top of handle, the affixed sleeve pipe in the top of knife bar, the card valve is installed in the side of sleeve pipe, and cutter head is a plurality of, is respectively a word, cross, the hexagonal cutter head, the terminal affixed inserted link of cutter head, inserted link can insert in the sleeve pipe fully, and round concave surface is offered in the bottom of handle, pastes magnet piece at the concave surface place, rectangular recess is offered on surface at handle, inner tip two sides at groove vertically connect turning cylinder, and holding rod is connected with turning cylinder, and the big I of holding rod places in the groove fully.

After adopting said structure, when needs are twisted the screw of different model, can select different cutter heads, cutter head end inserted link is inserted in the sleeve pipe, utilize the card valve to fix, but just the turn of the screw be followed closely, and need not to change screwdriver, very convenient; The user can utilize the magnet piece of handle bottom to adsorb the screw that screws down, in order to avoid screw is lost, influences work; Run into and get rusty or during the very tight screw of installing, the holding rod in the groove can be screwed out, one holds handle, and another holds holding rod, can easily back out screw, and is time saving and energy saving.

Compared with the prior art, the beneficial effects of the utility model are: rational in infrastructure, technology is simple, convenient and practical, be widely used, operate rationally, time saving and energy saving, increase work efficiency the service condition of providing convenience to people.
