Description

Multifunctional wrench

Technical field

The utility model is related to hardware ＆ tools production field, more particularly, to a kind of multifunctional wrench.

Background technology

Spanner is very common in daily life, is a kind of to twist the firmwares such as bolt, screw, nut using lever principle Hand tools.Existing spanner is varied, but most of spanner only possesses the simple function twisting bolt, but in reality Use during, people often also can use screwdriver, and at this moment people would have to carry spanner and screwdriver, not only simultaneously Bother and take up space, very inconvenient.

So a kind of structure of urgent need is simple, easy to use, both can twist bolt, and be also used as screwdriver to use , the patent of invention of Application No. 201210565987.2 discloses a kind of spanner with multiple types of tools, due to its instrument hinge It is connected on pinch bar it is impossible to realize increasing the effect of wrench torque.

Utility model content

The utility model aims to overcome that deficiency of the prior art, provides a kind of being not only convenient for carrying but also convenient use Multifunctional wrench.

The utility model is achieved through the following technical solutions：A kind of multifunctional wrench, including wrench body, described pulls Hand body includes handle and is arranged at the opening of handle first end, and the end face at described handle second end has near centre position Counterbore, is provided with contiguous block in described counterbore, described contiguous block installs along the two ends of pinch bar length direction near interposition It is equipped with the first driver bit and the second driver bit, the length respectively handle of described first and second driver bits is long The 1/3～1/2 and 1/6～1/4 of degree, described contiguous block and the described first or second driver bit can be fully recessed into counterbore Interior.

Preferably, described counterbore is set to stepped hole, and the hole of described stepped hole is takeed on towards handle second extreme direction.

Preferably, first paragraph counterbore rectangular cross-section, described contiguous block outer rim and the first paragraph counterbore in described hole shoulder outside Gap between madial wall is 0.2mm～0.5mm.

Preferably, the depth value of described first paragraph counterbore is 1cm～2cm.

Preferably, the one of madial wall of described first paragraph counterbore arranges fluted, described connection near centre position Projection with fit depressions is provided with block.

Preferably, described projection is telescopic elastic bumps.

Preferably, it is provided with the guide openings facilitating projection to slip into counterbore at the opening of described counterbore.

Preferably, the depth value 0.5cm～1cm bigger than the 1/2 of decreased food of the second segment counterbore of described hole shoulder inner side.

The beneficial effects of the utility model are：Wrench body arranges driver bit, two kinds can be met simultaneously Purposes, convenient and practical；Driver bit is longer, can play the effect increasing wrench torque.
