Description

Adjustable pliers

The invention relates to a pair of pliers, especially an adjustable pliers with adjustable jaw width.

The conventional pliers are composed of two pliers bodies pivotally arranged, and the two ends of the pliers body form a jaw and a handle, respectively. When operating the pliers, the user only needs to hold the handle to control the opening and closing of the jaw to perform operations such as clamping objects. Preferably, the pliers can be designed to be adjustable, that is, the width of the jaws can be adjusted, and the structure is generally provided with a long straight tooth groove on one of the pliers, while the other pliers have a ratchet The pivot shaft is arranged in the tooth slot, and the ratchet teeth of the pivot shaft can be separated from the tooth slot through control, so that the jaw body can slide relative to the jaw body, thereby adjusting the jaw width of the jaws. On the contrary, the pivot shaft can be ratcheted into the tooth slot through control to fix the position of the pivot shaft and grip the object with the set jaw width.

Taiwan Patent No. M507827 discloses a pliers structure that requires two bridge bodies to be assembled together by a bridge, which is not only inconvenient to assemble, but also affects the overall structure of the pliers. On the contrary, Taiwan Patent No. M503293 discloses another pliers structure, which does not require additional bridging parts, so that the two pliers bodies can be grouped together. One side of the pliers structure defines an assembly groove for the other After the jaws of the forceps pass, the two forceps can be further pivoted. However, the jaw size of this pliers structure is limited by the width of the assembly groove and is therefore thin, resulting in a limited bite force during operation. For this reason, Taiwan Patent No. M507827 discloses yet another pliers structure, which not only does not require additional bridging members to assemble the two pliers bodies together, but also retains a rich jaw, but sacrifices the thickness of the handle Come in exchange. In fact, the handle of the pliers is thin and needs a reinforcement sleeve to reinforce its structure.

The invention provides an adjustable pliers, which not only can set the two pliers together without additional bridging parts, so it is convenient to assemble, and still retains a rich jaw and handle without sacrificing the thickness of the handle. Does not affect its structural strength.

Specifically, the adjustable pliers of the present invention generally include a first pliers body, a second pliers body, and a pivoting adjustment portion. Wherein, the first forceps body has a body, and a jaw and a handle located at both ends of the body, wherein the body has a longitudinally penetrating adjustment groove, and a set of connecting grooves penetrating horizontally, the grouping groove includes Adjacent to an elongated slot section and a reaming section, the elongated slot section perpendicularly intersects the adjustment slot, and the reaming section is close to the handle. The second jaw body has a body, and a jaw and a handle located at both ends of the body, wherein the width of the jaw of the second jaw body is larger than the slot width of the elongated groove section of the first jaw body, but smaller than the The caliber of the reaming section of the first jaw body. In addition, the pivoting adjustment portion is used to pivotally connect the body of the first jaw body and the body of the second jaw body, and enable the second jaw body to be displaced relative to the first jaw body along the adjustment groove of the first jaw body To adjust the width of the jaws of the adjustable pliers.

Preferably, the adjustment groove of the first jaw body has two racks facing each other on the inner surface, the body of the second jaw body defines a pivot hole, the pivot hole of the second jaw body and the adjustment groove of the first jaw body Communicating, the pivoting adjustment part includes a pivot rod, a pressing part and an elastic member, the pivot rod is movably penetrated in the adjustment groove of the first jaw body and the pivot hole of the second jaw body, and protrudes on its outer surface A pair of tooth rows respectively engaged with the two racks of the adjusting groove are provided, the pressing part is fixed to the other end of the pivot rod, and the elastic member is elastically pressed against the inner side of the pressing part and the body of the first jaw body, The pressing part can make the tooth row of the pivot rod disengage from the two racks of the adjusting slot, and releasing the pressing part can make the tooth row of the pivot rod engage with the two racks of the adjusting slot again by the restoring force of the elastic member.

Preferably, the pivoting adjustment part includes a fixing member for fixing the pressing part to the other end of the pivot rod.

Preferably, the jaw portion of the first jaw body defines a nail-pulling cutout at its tip position for a steel nail to snap against to perform nail-pulling operation.

Preferably, a protrusion is formed on the outer surface of the turning joint of the jaw and the body of the first jaw body, and the area of the boss is slightly larger than the area of the head of the steel nail, thereby giving the adjustable pliers the function of a hammer .
