Abstract

A wrench with quickly angularly adjustable handle includes ahead section and a handle. The head section and the handle are pivotally connected with each other via a first and a second pivoted ends, whereby the handle can be up and down swung relative to the head section. The first and second pivoted ends respectively have a first and a second end faces facing each other. The first end face is formed with an upper and a lower contact sections. The second end face is formed with an upper and a lower abutment sections. The lower abutment section abuts against the lower contact section as a lower dead end of angular displacement of the handle. The upper abutment section abuts against the upper contact section as an upper dead end of angular displacement of the handle.

First claim

What is claimed is:

1. A wrench with quickly angularly adjustable handle, comprising:
a head section and a handle, the head section and the handle being pivotally connected with each other at a pivot axis via a first pivoted end and a second pivoted end, whereby the handle is moveable up and down angularly displaced relative to the head section between a lower dead end and an upper dead end; in a longitudinal direction of the wrench, the first pivoted end and the second pivoted end respectively having a first end face and a second end face facing each other, the first end face and the second end face each located on a side of the pivot axis away from the head section along the longitudinal direction, wherein:
the first end face of the first pivoted end having an upper section and a lower section, the upper section being formed with an upper contact section, while the lower section being formed with a lower contact section; the upper contact section being contiguous with the lower contact section; a first angle being contained between the upper contact section and the lower contact section;
the second end face of the second pivoted end also having an upper section and a lower section, the upper section having an upper abutment section, while the lower section having a lower abutment section; the upper abutment section being contiguous with the lower abutment section; a second angle being contained between the upper abutment section and the lower abutment section, the first angle being larger than the second angle; and
wherein, when the lower abutment section of the second pivoted end abutting against the lower contact section of the first pivoted end, the lower abutment section and the lower contact section serving as the lower dead end of the angular displacement of the handle and, when the upper abutment section of the second pivoted end abutting against the upper contact section of the first pivoted end, the upper abutment section and the upper contact section serving as the upper dead end of the angular displacement of the handle;
wherein at least one of the upper contact section and the upper abutment section is a slope relative to the first end face and the second end face, respectively; and
a gap defining the angular displacement is formed between the upper contact section and the upper abutment section when the lower abutment section abuts against the lower contact section at said lower dead end.

2. The wrench as claimed in claim 1 , wherein the upper contact section and the upper abutment section are slopes, while the lower contact section and the lower abutment section are planes perpendicular to the longitudinal direction of the wrench.

3. The wrench as claimed in claim 2 , further comprising an elastic assembly disposed on the upper contact section or the upper abutment section, when the handle is located at the upper dead end, the upper contact section and the upper abutment section elastically contacting each other via the elastic assembly.

4. The wrench as claimed in claim 2 , wherein the first pivoted end is a structure with at least one lug, the first end face being formed on an end face of the lug, the second pivoted end being a structure with at least one lug, the second end face being formed on one side of the at least one lug, the two pivoted ends being pivotally connected with each other by means of a pivot pin defining the pivot axis.

5. The wrench as claimed in claim 1 , wherein the upper contact section, the upper abutment section, the lower contact section and the lower abutment section are all slopes.

6. The wrench as claimed in claim 1 , wherein the upper contact section of the first end face is disposed on the first end face in a direction away from the second pivoted end.

7. The wrench as claimed in claim 6 , wherein the lower abutment section of the second end face is a plane perpendicular to the longitudinal direction of the wrench, while the upper contact section is a slope inclined away from the second pivoted end.

8. The wrench as claimed in claim 6 , further comprising an elastic assembly disposed on the upper contact section or the upper abutment section, when the handle is located at the upper dead end, the upper contact section and the upper abutment section elastically contacting each other via the elastic assembly.

9. The wrench as claimed in claim 1 , wherein the upper abutment section of the second end face is disposed on the second end face in a direction away from the first pivoted end.

10. The wrench as claimed in claim 9 , wherein the lower contact section of the first end face is a plane perpendicular to the longitudinal direction of the wrench, while the upper abutment section is a slope inclined away from the first pivoted end.

11. The wrench as claimed in claim 1 , further comprising an elastic assembly disposed on the upper contact section or the upper abutment section; when the handle is located at the upper dead end, the upper contact section and the upper abutment section elastically contacting each other via the elastic assembly.

12. The wrench as claimed in claim 1 , wherein the first pivoted end is a structure with at least one lug, the first end face being formed on an end face of the lug, the second pivoted end being a structure with at least one lug, the second end face being formed on one side of the at least one lug, the two pivoted ends being pivotally connected with each other by means of a pivot pin defining the pivot axis.
