Description

Collapsible afterburning screwdriver

Technical field

The utility model relates to a kind of collapsible afterburning screwdriver, and it is the specific purpose tool that is used for the turn of the screw.

Background technology

At present, the screwdriver that people use always (also claiming screwdriver or screwdriver), generally by screwdriver head, screwdriver rod and handle three parts are formed.During work, lever on the other hand, a hand-held pole clockwise or be rotated counterclockwise, because bottle opener does not have the arm of force of adding, so the bottle opener dynamics is little, does not make when afterburning effectively when running into the screw that needs in enormous quantities tighten or turn on and needing, and inefficiency influences work.

Summary of the invention

The purpose of this utility model is to provide a kind of screwdriver that adds the arm of force that has.Collapsible afterburning screwdriver is to comprise handle, screwdriver rod and screwdriver head, on the both sides of handle, be provided with the arm of force that adds of symmetry, it adds the arm of force is to be hidden in the handle both sides and the handle structure is an one, it is the cannelure that the handle both sides have symmetry, the upper end is provided with to adsorb and adds the magnet that the arm of force is used in the cannelure, it adds arm of force lower end and is arranged on the cannelure lower end by bearing pin spare, adds the interior magnet of arm of force upper end and groove and adsorbs mutually; In the handle central upper portion, be provided with simultaneously the loculus (also claiming to agree without prior consultation) of dress screwdriver head accessory.The utility model in use, when needs are afterburning when using, the folding arm of force that adds on the bottle opener is outwards broken off with the fingers and thumb out, hand-to-arm grip on the other hand, lever rotates according to the screw direction on the other hand; When running into the screw that is difficult to turn on, it can afterburningly screw out, and when running into the screw that need tighten, it can screw very soon, has improved operating efficiency.

In sum, the utility model modern design, simple in structure, the same with common bottle opener during usual the use, when running into that difficulty is back-outed or screw in enormous quantities will be turned on and needs when afterburning, this bottle opener is by adding the effect of the arm of force, make bottle opener increase dynamics, it is little to have solved common bottle opener dynamics, and the slow drawback of working has played good help for the staff improves work efficiency.
