Abstract

The invention relates to a gradual opening type open-end wrench with a multi-purpose opening, in particular to a wrench capable of screwing outer-hexagonal screws or nuts of different sizes. The gradual opening type open-end wrench with the multi-purpose opening is characterized in that two side faces of the opening of the wrench are widened in parallel in a stepped manner from the inside of the opening to the outside of the opening, and included angles between the stepped faces and the side faces of the opening are 120 degrees. When the opening of the wrench is aligned to to-be-screwed/unscrewed screws or nuts, the screws or nuts with larger sizes can be clamped by the two side faces with a larger gap therebetween at the front portion of the opening, the screws or nuts with smaller sizes can be clamped by the two side faces with a smaller gap therebetween at the inner portion of the opening by going deeper into the opening of the wrench, and after the screws or nuts are clamped, the screws or nuts can be tightened or loosened by pulling a wrench handle.

Description

The multiplex open formula open-end wrench gradually of a bite
Technical field
The present invention relates to the multiplex open formula open-end wrench gradually of a kind of a bite, especially outer-hexagonal screw or the nut that spanner can be turned several specification.
 
Background technology
Traditional wrench opening two sides distance does not equally change outward to opening by opening, can only use a kind of screw of specification or nut.
Summary of the invention
In order to overcome the deficiency that traditional spanner can only use a kind of screw of specification or nut, the invention provides the multiplex open formula open-end wrench gradually of a kind of a bite, one can turn outer-hexagonal screw or the nut of several specification spanner.
The technical solution adopted for the present invention to solve the technical problems is: the multiplex open formula open-end wrench gradually of a bite, wrench opening two sides are widened to opening between outer land stepwise is parallel by opening, and the angle of step surface and open side is 120 degree.Wrench opening is aimed at the screw or nut that will turn, the screw that specification is large or nut can be wider by the distance before opening two sides vise, the screw that specification is a little bit smaller or nut, by spanner mouth more deeply, allow the distance two sides narrowly of any in opening vise, pull spanner handle after vising and just can tighten or Unscrewed screw or nut.
The invention has the beneficial effects as follows, the multiplex open formula open-end wrench gradually of a bite, one can turn outer-hexagonal screw or the nut of several specification spanner.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is: the multiplex open formula open-end wrench appearance assumption diagram gradually of a bite.
In figure, 1. wrench opening, 2. step surface, 3. open side.
Detailed description of the invention
In FIG, the multiplex open formula open-end wrench gradually of a bite, wrench opening two sides (3) are widened to wrench opening (1) between outer land stepwise is parallel by wrench opening (1), and the angle of step surface (2) and open side (3) is 120 degree.Wrench opening (1) is aimed at the screw or nut that will turn, the screw that specification is large or nut can vise the two sides (3) wider by the distance before opening, the screw that specification is a little bit smaller or nut, by wrench opening (1) deeply a bit, allow the distance two sides narrowly (3) of any in opening vise, pull spanner handle after vising and just can tighten or Unscrewed screw or nut.

Claims (1)

1. the multiplex open formula open-end wrench gradually of a bite, it is characterized by: wrench opening two sides are widened to opening between outer land stepwise is parallel by opening, the angle of step surface and open side is 120 degree.
