Abstract

The utility model relates to a bridle spanner which drives an object to rotate in a tying way for the purpose of pulling, which comprises a grip and a bridle mounted on the grip, characterized in that the grip is mounted with a built-in fitting which clamps the bridle between the built-in fitting and the grip. When in use, the bridle is tied on a pipe and on a can bottle cap, the free end of the bridle is tightened and clamped by the built-in fitting, thereby pipes and can bottle caps with various specifications can be tightened or loosened. Because the bridle has certain flexibility, the object which needs to be screwed can be conveniently hitched, and the impression can not be left on the screwed object.

Description

Chain wrench

[technical field]

The utility model relates to a kind of hand tools, especially a kind ofly drives object in the mode of tying up and rotates and reach the Chain wrench of pulling purpose.

[background technology]

Existing spanner bore adjustable extent is little, the workpiece of different model often needs to use the spanner of different size, especially outer surface do not have Gong to pull clamping face the time (such as circular pipe), be difficult to reach the purpose of pulling with existing conventional spanner, and special-purpose pipe vice can stay impression even crackle after the use on pipe.Moreover existing spanner can not be opened the object such as the can bottle cap, the function singleness of feasible existing spanner.

[utility model content]

The technical assignment of the technical problems to be solved in the utility model and proposition is to overcome the above-mentioned defective that existing spanner exists, and a kind of Chain wrench easy to use, multi-functional is provided.For this reason, the utility model is taked following technical proposals:

A kind of Chain wrench comprises handle and is installed in band on the handle, it is characterized in that being equipped with on the described handle one band is clamped in holder between itself and the handle.During use, band is banded in pipe and Cans cover, the free end of tension band also clamps by holder, the pipe of all size and can bottle cap can be tightened or unclamp.Because band has certain flexibility, can entangle the required object that turns easily, and can not stay impression on the object of twisting.

Described Chain wrench is characterized in that described holder for be installed on the eccentric wheel on the handle with rotating manner, and eccentric periphery has teeth groove; The teeth groove that makes its periphery is installed on the eccentric wheel relies on spring in handle.Be convenient to strain band, and in pulling process, can hold tightlyer by the halved tie strap clamp.

Described Chain wrench is characterized in that a reference column is arranged on the described handle, has the annular groove corresponding with reference column on the eccentric wheel, and spring places in the annular groove, and the one end hook hangs on the reference column.Compact conformation.

Described Chain wrench is characterized in that the middle part of described handle has the guide groove that moves therein for band; The cambered surface of handle front end is provided with teeth groove.

Described Chain wrench is characterized in that there is a recess at position, described handle upper rail right side, and described holder is positioned at this recess; The left side wall of described guide groove has the arcuation depression corresponding with holder.

Described Chain wrench is characterized in that having a groove on the described handle, and a fixed leg is arranged in the groove, and an end of described band is walked around fixed leg and passed band by a screw and is fixed on the handle.

Below in conjunction with Figure of description the utility model is described further.

[specific embodiment]

As shown in Figure 2, the back side of handle 4 has groove 14, and fixed leg 10 is arranged in the groove 14, and an end of band 1 places in the groove 14 and walks around fixed leg 10 and stacked for two-layer, and passes band by screw 9 and be fixed on the handle 4.In order to increase the fastness that band connects, can when fixing band, pick glue, the string course poststack is bonded together.

As shown in Figure 3, the front of handle 4 is divided into left and right sides two parts by guide groove 8: position, guide groove 8 right side is a recess 13, and rotating shaft 11 and reference column 12 are arranged in the recess 13; The guide groove left side wall corresponding with recess 13 is arcuation depression 3.The handle cambered surface of recess 13 upper ends is provided with teeth groove 5.

As shown in Figure 4, offer the annular groove corresponding with reference column 7 on the eccentric wheel as holder, annular groove 7 is built-in with spring 6, and eccentric periphery is provided with teeth groove 15 equally.

As shown in Figure 1, eccentric wheel 2 is installed in the rotating shaft 11 of recess 13, and it is 3 corresponding that its teeth groove 15 and the arcuation of guide groove left side wall cave in, and an end hook of spring 6 hangs on the reference column 12, its other end is conflicted in the end of annular groove 7, thereby makes the teeth groove 15 of eccentric wheel 2 cave in 3 near arcuation.

During use, the free end of band 1 is walked around similar articles such as pipe or can bottle cap, pass the guide groove 8 on the handle, being clamped in the teeth groove 15 of eccentric wheel periphery and the arcuation of guide groove left side wall caves between 3, at this moment, band can only be tightened up, and can not loosen, after waiting to strain band, can pull object easily; Finish using, in the time of need unclamping object, only with hand upwards promotes eccentric outer end (right-hand member among Fig. 1), can contact the clamping to band, and unclamp the object of being pulled.
