Abstract

The utility model relates to a multifunctional adjustable wrench which comprises a wrench body as a handle as well, a wrench opening and a coupling shaft, wherein the coupling shaft is positioned in an elongated slot of the wrench body, and one side of the elongated slot is provided with skewed teeth which are matched with toothed racks on the circumferential surface of the coupling shaft. When the coupling shaft ascends and descends in the elongated slot, the wrench opening can be opened and closed; the gripping surfaces of the wrench body wrench opening both have the included angle of 120 DEG; concave-convex toothed racks are arranged on the gripping surfaces. Both sides of the handle of the wrench body are provided with grooves, a cross-head and a flat-head screwdrivers are embedded in the grooves, and the screwdrivers can be rotated out from the grooves. The adjustable wrench has flexible and convenient use; the adjustable wrench can tightly clamp hexagonal or square nuts, screws and pipe fittings with difficult slipping, and has the functions of wrenches, pipe wrenches and screwdrivers.

Description

The multifunction active wrench

The utility model belongs to mechanical small tool, relates in particular to monkey wrench.

The surface of the gripping objects of monkey wrench commonly used is a smooth surface, and spline does not easily skid off during the clamping securing member, after skidding off, must readjust and pull a mouthful folding size, could continue gripping objects, influence operating efficiency, in addition because clamping face does not have teeth groove, can not the clamping pipe fitting.

The purpose of this utility model provides a kind of multifunction active wrench, and this spanner is convenient, flexible when mouthful folding is pulled in adjusting, during gripping objects, is difficult for skidding off, and has the function of pipe wrench and screwdriver.

For achieving the above object, take following technical scheme: the multifunction active wrench is made of pulling body, pull mouth and will pull body and pulling a mouthful coupling spindle of combining of double as handle, pull elongated slot is arranged in the body, one side of elongated slot has helical teeth, this helical teeth cooperates with tooth bar on the coupling spindle periphery, and pulling the body top has clamping ramps, and there is V-shaped groove on the inclined-plane, it is with to pull mouthful V-arrangement clamping face corresponding, and pulling body all has concavo-convex tooth bar with the clamping face of pulling mouthful.

Owing to of the present utility modelly pull body and pull mouthful an employing coupling spindle and connect, as long as on, stir the coupling spindle in pulling the body elongated slot down, just can regulate the folding of pulling mouth easily, one side of pulling in the body elongated slot has helical teeth, because profile of tooth is right angled triangle or zigzag, after pulling mouth and regulating on request, can not go up cunning, keep pulling a mouthful size constancy, effect with solid wrench, in addition, pulling body is the V-arrangement face with the clamping face of pulling mouth, its V-arrangement angle is 120 °, concavo-convex tooth bar is arranged, therefore for six sides on the clamping face, sides nut, head of screw and pipe fitting all can clip, and are difficult for slippage, groove in the both sides of pulling the body handle end is embedded with cross and flathead screwdriver, needs the time spent can be easily to stretch out behind the Rotate 180 ° in the groove.This monkey wrench has multiple function, and is easy to use flexible.

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of first kind of embodiment of the utility model;

Fig. 2 is the A-A profile of Fig. 1;

Fig. 3 is the handle end schematic diagram;

Fig. 4 is Fig. 3 left view;

Fig. 5 is the front view of coupling spindle;

Fig. 6 is the left view of Fig. 5.

Embodiment 1: monkey wrench is pulled body 1 by double as handle 13, pull mouth 5 and coupling spindle 9 compositions, pull elongated slot 2 is arranged in the body 1, one side of elongated slot 2 has helical teeth 3, the shape of cross section of helical teeth 3 is right angled triangle or zigzag, the stage casing of coupling spindle 9 is positioned at pulls body elongated slot 2, the tooth bar 14 that cooperates with helical teeth 3 is arranged on its periphery, tooth bar 14 is parallel with axis, tooth pitch is identical with helical teeth 3 tooth pitches, the two ends of coupling spindle 9 are cylindrical pivot pin 10, pull body 1 top clamping ramps 6 is arranged, there is V-shaped groove 4 at the middle part on this inclined-plane, it is with to pull mouthful V-arrangement clamping face 8 corresponding, the angle of V-shaped groove 4 and V-arrangement clamping face 8 is 120 °, pull body clamping ramps 6 and pull concavo-convex tooth bar 7 is all arranged on mouthful V-arrangement clamping face 8, pull mouthful 5 lower end jags, pull body 1 and be clipped in the jag place, the jag end has pin-and-hole 11, and the cylinder pivot pin riveted joint at it and coupling spindle 9 two ends is pulled body handle 13 and is combining structure, on the branch, following two joints and connect with rectangle pin 12, handle 13 lower ends are than the upper end 10～20mm that takes over, and the both sides, lower end are fluted 15, and Phillips screwdriver 16 and flathead screwdriver 17 embed respectively in the groove 15, and terminal hinged with groove 15, the time spent is with

screwdriver

16,17 take out behind the Rotate 180s ° in the groove 15.

Embodiment 2: pull the handle 13 of body 1 lower end and pull body 1 coenosarc, other structure is identical with embodiment 1.

Use monkey wrench,, regulate the height of coupling spindle 9 during pulling body elongated slot 2, wait to pull body 1 and open to big or small when consistent, but just gripping objects carries out fastening or loose unloading with object with pulling mouth 5 at first according to the thickness that is held object.
