Abstract

The utility model relates to a pair of multipurpose flat pliers belonging to the field of machine tools. The utility model is mainly used for clamping work pieces and cutting iron wires and used as an adjustable wrench for wrenching screws and as a combined turning tool. The pliers openings of the multipurpose flat pliers are always parallel to each other in the clamping process, so that work pieces can be clamped tightly and reliably, and simultaneously, the cutting force is large. The utility model also has multi-purpose as one tool. The multipurpose flat pliers can be used as an adjustable wrench for wrenching screws, and after matched with a turning tool head, the multipurpose flat pliers can be used as a combined turning tool. The utility model has the advantages of convenient use and portability.

Description

Multipurpose flat-jaw vice

Should many belong to the machine tool category with flat-nose pliers

The cutting pliers of selling on the market all are X-shaped as scissors now, jaw tilts in the process under folder, it is exactly flat-nose pliers, also just jaw is extended, one among a small circle in approximate flat mouthful, clamping shakiness is like this damaged the edge of work easily, active spanner also has only a circle circle to go to twist, so that jaw and cap nut size to fit.

This utility model is mainly used to holding workpiece, cuts off iron wire, makes active spanner and removes screw, mixes various rotating tool heads and can also make screw assemblage usefulness.

This utility model primary structure is a parallel bar mechanism.This is a kinematic sketch of mechanism to see accompanying drawing 5..According to these motion of mechanism characteristics, two jaws remain parallel in the process that moves up and down.All have slideway at upper and lower jaw part rear portion, the screw pin that is installed on the upper and lower handle can inside slide.Cut off the sword design and under upper jaw 3 reaches, on the handle 9,, cut off iron wire along with the open and close movement of jaw.In order to have the function of active spanner, upper jaw 3 is designed to "T"-shaped, following convex portion is a tooth bar, and the centre has slideway, and the screw pin on the lower jaw 4 can slide in slideway, and tooth bar can be meshed with double-screw bolt 10.The double-screw bolt axle center has through hole, and the thin axle of eccentric shaft 7 can rotate in the hole, and thin shaft head is begun in the pit of lower jaw 4, and thick axle is loaded in the mating holes of lower jaw 4, can rotate therein, and shell fragment 6 and holding screw 5 are housed below.When using as spanner, earlier pliers is clamped and needed stubborn nut, promote double-screw bolt 10 middle parts then, make it rotate 180 degree with eccentric shaft, twisting double-screw bolt simultaneously makes it rotate maximum half-turns around the little axle of eccentric shaft, can jaw be locked with the tooth bar engagement, at this moment the little shaft head of eccentric shaft falls into the front pit.Rear portion at following handle 9 is provided with the screw assemblage chuck, and various tool can be installed, and the function of this utility model is increased greatly.

1, under folder, all the time be parallel in the process with the flat-nose pliers jaw owing to being somebody's turn to do many, so holding workpiece is very capable, reliable.

2, owing to longer than existing vice, so cut-out power is big at the cutting-off process king-rod thick stick arm of force.

3, can be used as active spanner usefulness, and need not resemble the common active spanner one enclose the land stubborn, so action is fast.

4, mix various rotating tool heads, can be used as screw assemblage usefulness, a tool is used more.

This utility model application has 7 accompanying drawings.Fig. 1 is a front view, and Fig. 2 is a vertical view, and Fig. 3 is a bottom view, and Fig. 4 is a left view, and Fig. 5 is a kinematic sketch of mechanism, and A-A is a full sectional view, expression be the whole open duties of jaw.Because rearview has only incision different with front view, thus the Rear View Ommited, and add a backsight partial view B-B, right view omits.

In A-A figure, 1 is up knob; 2 is screw pin (totally 5); 3 is upper jaw; 4 is lower jaw; 5 is screw; 6 is shell fragment; 7 is eccentric shaft; 8 is casing coupling; 9 are following handle; 10 is double-screw bolt.

The reference mode that realizes this utility model is as follows:

Upper jaw 3, lower jaw 4 at first with the material die forging, are milled out plane, slideway, the flank of tooth, boring, and the employing broaching machine is opened the inclined to one side hole on the lower jaw 4, tapping, bar hold reticulate pattern, heat treatment then, reaching down to up knob 1, handle 9 adopts round steel to forge, groove milling, turning, boring then, milling cutter sword, heat treatment, double-screw bolt 10 adopts round steel car system, boring, heat treatment.

Claims
