Abstract
The utility model belongs to a quick-action pipe wrench of a manual hardware tool, which is provided with a moving wrench jaw, a fixing wrench jaw and a handle. The tooth profile on the fixing wrench jaw is in the form of outer arc involute tooth surface, and the tooth profile is inlayed on the front end of the handle through an elastic cylindrical pin. The front inside of the moving wrench jaw is in the form of V-shaped inner tooth surface, and a protrusion is positioned on the upper part of the moving wrench jaw. The back part of the moving wrench jaw is provided with a hole which is connected with the hole provided with a groove on the handle through a rivet shaft, the tail part of the moving wrench jaw is provided with a pullback spring which is fixed in the groove on the handle by screws through a press plate, and the moving wrench jaw which can wobble is used for clamping a work piece. The utility model is of simple and reasonable structure, of light weight, of one-handed operation, of convenient use, of fast adjusting speed, of labor saving, of reliable operating performance and of high efficiency.
Description
Affiliated technical field
The utility model belongs to manual hardware ﹠ tools, specifically a kind of fast pipe twist.
Background technology
Pipe vice in the market mostly is that regular jaw, moving jaw, pincers handle body, adjusting nut are arranged, and rotates adjusting jaw opening amount size by nut, threaded engagement and carries out work, is widely used in the circular tubing workpiece of clamping and turn-knob.Rotation adjusting nut during use by adjusting moving of moving jaw, changes the opening amount size of moving jaw relative fixed jaw, the circular tubing workpiece of clamping.In the process of using, need bimanualness, constantly rotate adjusting nut, adjust jaw opening amount, therefore more loaded down with trivial details, waste time and energy; When clamping tubing workpiece or pipe, 2 of pipe vice jaws are stressed, skid the easy damaged surface of the work easily.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiency of above-mentioned technology, to provide a kind of simple in structure, singlehanded front-operated, and folding is flexible, clamping work pieces voluntarily, easy to use and reliable fast pipe twist.。
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of fast pipe twist, be provided with moving jaw, regular jaw, handle, it is characterized in that the profile of tooth on the regular jaw is the outer arcuate involute flank, be embedded in the handle front end by elastic cylindrical pin, the anterior inboard V-shaped inner toothed surface of moving jaw, moving jaw top is provided with a projection, the rear portion is provided with a hole and is connected by the hole that rivet shaft and handle are provided with groove, the moving jaw afterbody is provided with extension spring and is screwed in the groove on handle by the sheet spring, moving jaw can be swung, clamping work pieces.
The utility model is simple and reasonable for structure, and is in light weight, and one-hand operation is easy to use, and governing speed is fast, save trouble and labor, reliable working performance, efficient height.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described in detail.
Fig. 1 is a structural representation of the present utility model.
Mark among the figure: 1, moving jaw, 2, regular jaw, 3, elastic cylindrical pin, 4, rivet shaft, 5, extension spring, 6, the sheet spring, 7, screw, 8, handle.
The specific embodiment
As shown in Figure 1, a kind of fast pipe twist, be provided with moving jaw 1, regular jaw 2, handle 8, profile of tooth on the regular jaw 2 is the outer arcuate involute flank, be embedded in handle 8 front ends by elastic cylindrical pin 3, moving jaw 1 anterior inboard V-shaped inner toothed surface, moving jaw 1 top is provided with a projection, the rear portion is provided with a hole and is connected with the hole that handle 8 is provided with groove by rivet shaft 4, moving jaw 1 afterbody is provided with extension spring 5 and is fixed in the groove on the handle 8 by sheet spring 6 usefulness screws 7, moving jaw 1 can be swung, clamping work pieces.During use, press moving jaw 1 top and be provided with a projection, moving jaw 1 is under the effect of extension spring 5, produce during moving jaw 1 clamping work pieces and clamp pretightning force, can not produce skidding,, make it when screwing workpiece, can freedom to screw repeatedly and needn't regulate because moving jaw 1 is to be connected and can to swing with rivet shaft 4 with handle 8, regular jaw 2 adopts and handle 8 mosaic textures, no matter the workpiece that clamps during work can not produce loosening in any position of regular jaw 2.The V-arrangement inner toothed surface of moving jaw 1 adopts little tooth square profile of tooth, increases the number of teeth of engagement pipe, and clamping work pieces is firm, and the while is the easy damaged workpiece not.During work, the moving jaw V-arrangement flank of tooth and regular jaw involute flank clamp workpiece, and moving jaw 1 produces pretightning force under the effect of extension spring 5, also can not skid to come off during release handle 8 in the use and leave workpiece, reliable operation.Be suitable for different calibers and suffer from one's own actions clamped position under the effect of one hand, the opening amount satisfies the clamping diameter of international standard defined and the length overall scope of international standard regulation, and easy to use, governing speed is fast, save trouble and labor, reliable working performance, efficient height.
