Title:
ADJUSTABLE WRENCH HAVING DOUBLE-V-SHAPED WRENCH MOUTH
Document Type and Number:
WIPO Patent Application WO/2016/192167
Kind Code:
A1
Abstract:
An adjustable wrench having a double-V-shaped wrench mouth comprises a wrench main body (1) and a wrench mouth (3) provided on the top of the wrench main body. The wrench mouth is formed by two jaws (2) on the left and right. Opposing inner sides of the two jaws are provided with symmetrical triangle grooves (4) thereon. The inner sides of the two jaws are V-shaped, and have two neighboring contact surfaces (5) for contacting a bolt or a nut. The two jaws of the adjustable wrench form a quadrilateral mouth, such that the bolt or nut bears the force by four contact surfaces rather than two contact surfaces, thus stressed evenly and being less prone to slipping in disassembly of the bolt or nut.
