Description

Spanner

The utility model relates to a kind of spanner.

ZL93244943.3 has introduced a kind of spanner, is made of handle and active pincers hook, and there is arcwall face the handle upper end, and there are four faces pincers hook inboard surely by certain angle.Though this spanner has suitable many, the advantage of simple structure of nut kind, and five faces are arranged in its jaw, and is too much to the containing of nut.When work, require to leave more operating position around the nut, can not equally with monkey spanner when some is barrier by the nut, still can use.When the nut axis was parallel to the ground, when especially requiring active pincers hook downward, must have a hand rest firmly to clamp hook could work in addition, as long as can not equally with adjustable wrench there be a hand just can work.Above-mentioned deficiency has limited the scope of application of workplace.

The purpose of this utility model is to remedy above-mentioned deficiency, provide a kind of can the big spanner of the scope of application of the same workplace with adjustable wrench.

Spanner provided by the utility model, handle (1) and active pincers hook (2) constitute, and handle (1) upper end has end points, active pincers hook (2) inboard to face directly and two faces of curved surface, has one of end points to intersect on its mean camber and the handle.The jaw of spanner promptly is made of two faces of active pincers hook inboard and the end points on the handle.

The spanner of this structure because its containing to nut is few, still has two limits to stay outside the jaw for hex nut, and the operating position of spanner is little, endure when some obstacle of nut side.Also can make pipe vice uses.

Now described in detail in conjunction with the accompanying drawings;
