Abstract

The utility model relates to a friction pipe wrench. The friction pipe wrench comprises a clamping section, a transition section, a jaw and a handle, wherein the clamping section, the transition section, the jaw and the handle are in rotating connection in sequence through pins; the joint between the clamping section and the transition section and the joint between the transition section and the jaw are respectively provided with a movable jaw, wherein the movable jaws are both fixedly connected to the transition section through screws; the jaw is provided with the handle; the circular arc radius of the inner surface of each movable jaw ranges from 35mm to 48mm. The friction pipe wrench has the advantages that by arranging the movable jaws at the joint between the clamping section and the transition section and the joint between the transition section and the jaw respectively, the friction pipe wrench can adapt to pipes with different specifications, the friction pipe wrench is convenient to maintain after being worn, and the working diameter of the friction pipe wrench can be quickly changed.

Description

A kind of Friction spanner for pipe
Technical field
The utility model relates to a kind of Friction spanner for pipe.
Background technology
Friction spanner for pipe is to utilize the annular friction face that jaw surrounds to hold the instrument that body is rotated dismounting tightly, has clamping force large, the feature of unsuitable injured surface.The general adjusting range of existing Friction spanner for pipe is minimum, once vice jaw surface weares and teares or pipe diameter is less than normal, just cannot effectively use.Another pipe wrench is the pipe part of corresponding a kind of specification only, if often operate the pipe part of different size, and will supporting different Friction spanner for pipe.
Utility model content
The purpose of this utility model is to provide a kind of Friction spanner for pipe, to overcome prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of Friction spanner for pipe, comprise the clamping joint, transition segment, jaw and the handle that by pin, are rotationally connected successively, described clamping joint is equipped with moving jaw with the junction of described transition segment and the junction of described transition segment and described jaw, and described moving jaw is all fixed on described transition segment by screw.
Further, described jaw is provided with handle.
Further, described moving jaw inner surface arc radius is 35-48mm.
The beneficial effects of the utility model are: by the junction clamping junction, transition segment and the jaw of joint and transition segment, moving jaw is set, make this Friction spanner for pipe can adapt to the pipe fitting of different size, also convenient maintenance after wearing and tearing, and can change fast working diameter.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the structural representation of Friction spanner for pipe described in the utility model embodiment.
In figure:
1, clamp joint; 2, transition segment; 3, jaw; 4, moving jaw; 5, screw; 6, handle; 7, pin; 8, handle.
The specific embodiment
As shown in Figure 1, a kind of Friction spanner for pipe described in the utility model embodiment, comprise the clamping joint 1, transition segment 2, jaw 3 and the handle 6 that by pin 7, are rotationally connected successively, described clamping joint 1 is equipped with moving jaw 4 with junction and the described transition segment 2 of described transition segment 2 with the junction of described jaw 3, and described moving jaw 4 is all fixed on described transition segment 2 by screw 5; Described jaw 3 is provided with handle 8.
Described moving jaw 4 inner surface arc radius are 35-48mm.
During use, workpiece is placed on to suitable jaw 3 positions, grasps handle 6 and handle 8, simple to operate.User can select suitable moving jaw 4 according to workpiece size, also replaceable during moving jaw 4 serious wear.
The utility model is not limited to above-mentioned preferred forms; anyone can draw other various forms of products under enlightenment of the present utility model; no matter but do any variation in its shape or structure; every have identical with a application or akin technical scheme, within all dropping on protection domain of the present utility model.
