Problems solved by technology

[0003] A traditional wrench generally includes two parts, a jaw and a handle. The jaw can use the principle of leverage after clamping bolts and other objects to tighten or loosen bolts and other objects through the rotating handle. During use of this traditional wrench, The size of the wrench buckle can only be changed in the form of thread rotation. For some occasions where the space is relatively narrow, the size of the wrench jaw can only be adjusted before use. Too large or too small to provide effective action and torque to objects such as bolts that need to be turned

Embodiment 1

[0030] A multi-functional quick wrench, comprising an upper jaw 1, a lower jaw 2 and a handle 3, the near end of the upper jaw 1 is provided with a protrusion 11, and the upper end of the handle 3 is provided with a waist-shaped through hole. hole 31, one side of the waist circular through hole 31 is connected with a push rod 4 by a bolt, the other end of the push rod 4 is connected with the protrusion 11 by a bolt, and the end of the push rod 4 can be set as Fork mouth 41 forms, adopt pin shaft to be sleeved on the protrusion 11 of upper jaw, as Figure 5 As shown, the tail end of the upper jaw 1 and the tail end of the lower jaw 2 are respectively fixedly connected to the upper end of the handle through the bolts passing through the waist circular through hole 31, and the protrusion 11 is connected to the upper end of the handle. A two-force bar is formed between the jaws 1, and the upper jaw 1 and the lower jaw 2 can achieve the effect of clamping or loosening by moving wit...

Embodiment 2

[0037] The two ends of push rod 4 also can be set to common straight plate shape, as Image 6 As shown, it is directly connected to the handle 3 and one side of the upper jaw 1 through bolts or pin shafts, and the shape of the jaw formed between the upper jaw 1 and the lower jaw 2 is oval, such as figure 1 Shown, all the other parts are with embodiment 1.

Embodiment 3

[0039] The shape of the jaw formed between the upper jaw 1 and the lower jaw 2 is quadrilateral, such as Figure 7 Shown, all the other parts are with embodiment 1.

Abstract

The invention relates to the technical field of mechanical tools, in particular to a multifunctional speed wrench which comprises an upper jaw, a lower jaw and a handle, wherein a boss is arranged atthe near tail end of the upper jaw; a kidney-shaped circular through hole is formed in the upper end of the handle; one side of the kidney-shaped circular through hole is connected with a push rod through a bolt or a hinge pin; the other end of the push rod is connected with the boss through the bolt or the hinge pin; the tail end of the upper jaw and the tail end of the lower jaw are fixedly connected with the upper end of the handle through the bolts or the hinge pins penetrating through the kidney-shaped circular through hole; and a rocking bar sliding block mechanism is formed among the push rod, the boss and the handle. The multifunctional speed wrench is provided with a sliding rod connected with the upper jaw and the lower jaw; the size of the jaw is adjusted through the sliding rod, and the traditional wrench operating manner is changed, so that the multifunctional speed wrench can be freely used in the working environment with a narrow space; and in addition, the manner that the rocking bar sliding block mechanism is combined with the sliding rod is adopted, so that an article can be clamped more tightly when larger force is applied.

Description

technical field [0001] The invention relates to the technical field of mechanical tools, in particular to a multifunctional quick wrench. Background technique [0002] A wrench is a tool for turning fastening or loosening bolts, round objects and other objects that are difficult to rotate, and is widely used in the fields of mechanical assembly and maintenance. [0003] A traditional wrench generally includes two parts, a jaw and a handle. The jaw can use the principle of leverage after clamping bolts and other objects to tighten or loosen bolts and other objects through the rotating handle. During use of this traditional wrench, The size of the wrench buckle can only be changed in the form of thread rotation. For some occasions where the space is relatively narrow, the size of the wrench jaw can only be adjusted before use. Too large or too small to provide effective action and torque to objects such as bolts that need to be turned. Contents of the invention [0004] Th...
