Title:
ADJUSTABLE PLIERS
Document Type and Number:
WIPO Patent Application WO/2018/148892
Kind Code:
A1
Abstract:
A pair of adjustable pliers comprises a first handle (5) and a second handle (9). Each of the front ends is provided with a clamping portion (2, 1), and the two clamping portions form a jaw. The first handle and the second handle are disposed in an intersecting manner and are relatively fixed by means of a connecting mechanism. The second handle is provided with a long toothed groove (91) at the position of the connecting mechanism, and the inner portion of the toothed groove is provided with a tooth band (92). The connecting mechanism comprises positioning clamping teeth (6) disposed in the toothed groove and a linkage mechanism connected to the positioning clamping teeth. The positioning clamping teeth are provided with side teeth (61) and occlude with the tooth band on the toothed groove. The linkage mechanism comprises a triggering shaft (7) connected to the positioning clamping teeth, and the triggering shaft is provided with a triggering portion (71). The linkage mechanism is configured to drive the positioning clamping teeth to rotate, so that the side teeth on the positioning clamping teeth are separated from the occlusion with the tooth band, so that the first handle can move relative to the second handle along the toothed groove by means of the movement of the connecting mechanism. The pair of adjustable pliers allowing directly pushing the right-hand handle, can make rapid one-way adjustment, and is convenient and labor-saving.
