Abstract
The utility model discloses a novel adjustable spanner composed of one polygon hole and an adjustable bar, which is mainly used for wrenching hexagon screws and nuts. The utility model has the advantages of simple manufacturing process, low cost, convenient application, etc., and can wrench screws and nuts of different sizes.
Description
The utility model is a kind of spanner, is used for pulling of hex screw and nut.
Existing spanner is a lot, and monkey wrench is arranged, solid wrench, and combination wrench, double offset ring spanner, inner hexagon spanner, box spanner, ratchet spanner or the like respectively has excellent, shortcoming.
The purpose of this utility model is that a kind of production technology of design is simple, and cost is low, and is movable adjustable, can pull the hex screw that varies in size and the spanner of nut.
The feature of this monkey wrench is made up of the polygonal hole and the threaded modulation bar of a band screw.
Accompanying drawing is the vertical view of novel movable spanner.
At spanner 1 polygonal hole (4) is arranged, this hole is that the regular hexagon expansion forms, polygonal hole successively adjacent three minor faces (a, b, c) is the regular hexagon limit, article two, long limit (d, e) is the prolongation limit on regular hexagon limit separately, on the intersection point of this two long limits (d, e) extended line and relative edge's (b) the center line screw is arranged, the screw thread on this screw matches with screw thread in modulation bar (2).
This spanner can be made with technologies such as punching press or castings, during application nut (3) is put into polygonal hole, rotates modulation bar (2), is fixed, and can tighten or loosening screw and nut.
The utility model activity is adjustable, can pull the screw and the nut that differ in size, and it is convenient to use.
Claims (4)
1, a kind of novel movable spanner is characterized in that being made up of the spanner (1) and the modulation bar (2) of a band polygonal hole (4), screw.
2, according to the described monkey wrench of claim 1, it is characterized in that said polygonal hole (4) forms for the regular hexagon expansion, its adjacent successively three minor faces (a, b, c) are orthohexagonal three limits, and two long limits (d, e) are the prolongation limit of the alternate edge of regular hexagon.
3,, it is characterized in that on the intersection point of two long limits (d, e) extended line of said polygonal hole (4) and relative edge's (b) the center line screw being arranged according to the described monkey wrench of claim 1.
4,, it is characterized in that the screw thread on the said modulation bar (2) and the threads engaged of the screw on the center line according to the described monkey wrench of claim 1.
