Abstract (en)
An open end wrench (10) includes first and second jaws (23, 24). The first jaw (23) includes an arcuate sliding groove (27) having two support wall faces (272, 273) and an arcuate sliding wall face (271) between the support wall faces (272, 273). A slide (30) is slideably received in the sliding groove (27) and includes an arcuate sliding face (31) slideable along the sliding wall face (271). Two wings (37) respectively extend from top and bottom faces (301, 302) of the slide (30). Top and bottom extension faces (36) extend from a wrenching face (32) of the slide (30) and are located on inner faces (371) of the wings (37). A spacing (L) is formed between an outer face (372) of each wing (37) and one of the support wall faces (272, 273) to avoid friction, allowing smooth movement of the slide (30) between an driving position and a non-driving position.
