Abstract

The utility model relates to a wrench used on a machine, particularly a combined internal hexagonal wrench. The utility model is composed of a wrench head (1), wrenches (2), a screw bolt (3), a bracket (4), and a handle (5), wherein, the wrenches (2) are respectively fixed on different planes of the wrench head (1), and the wrench head (1) is fixedly connected with the bracket (4) through the screw bolt (3). Because a plurality of wrenches which are usually used in mechanical process are combined together in the utility model, one combined wrench can be used for disassembling screw bolts with four specifications. The utility model which has the advantages of simpleness, convenience, practicality, time saving, and labor saving lengthens the length of a short angle, enhances the intensity of the bent head position of the combined wrench, and reduces the phenomenon of rupture.

Description

The combination inner hexagon spanner

The utility model relates to a kind of spanner that mechanically uses, particularly a kind of combination inner hexagon spanner.

In mechanical processing process, often use inner hexagon spanner.The general complete outfit of standard inner hexagon spanner, 13 in a cover.In use, have only several using always, during hexagonal is pulled in the generally held standard use, the corresponding a kind of bolt of a kind of specification, different bolts, need to change the spanner of different size, very inconvenient in the use, influence operating efficiency, standard inner hexagon spanner length angle differs more than three times, as S10 inner hexagon spanner and angular length L=125mm, short angular length H=40mm, length angle ratio: 3: 1, in use, people's hand-power generally is certain, (H), learn that the moment that the length angle is subjected to differs greatly according to moment M=F.L, when using short angle to dismantle screw, phenomenon of rupture appears easily in the elbow.

The purpose of this utility model is to provide a kind of combination inner hexagon spanner that uses on lathe, for easy to use, enhance productivity, and easy fracture not, and is simple in structure, overcome the problem of above-mentioned existence.

The purpose of this utility model is to realize like this, it is made up of driving end (1), spanner (2), bolt (3), support (4), handle (5), the spanner of four different sizes (2) is separately fixed on the Different Plane of driving end (1), driving end (1) is fastened on the support (4) by bolt (3), support (4) is rectangular, Yi Bian be connected with handle (5).

The utility model is because several wrench combination commonly used in the machining together, can dismantle 4 kinds of specification bolts with a combination wrench, simple, convenient, practical, save time, laborsaving, the length at the short angle of having extended, strengthen the intensity of combination wrench elbow, significantly reduced phenomenon of rupture.

Accompanying drawing is a structural representation of the present utility model.

Below in conjunction with accompanying drawing the utility model is illustrated.

The purpose of this utility model is to realize like this, it is by driving end (1), spanner (2), bolt (3), support (4), handle (5) is formed, in mechanical processing process, often use inner hexagon spanner, the utility model adopts four sizes to be respectively S6, S8, S10, the standard inner hexagon spanner of S12, be welded on respectively on four faces of square driving end (1), bolt (3) passes two other face of driving end (1), and be fixed on the limit of rectangle support (4), driving end (1) can rotate around bolt (3) on support (4), handle (5) is threaded and is fixed on the another one limit of the rectangle support (4) corresponding with driving end (1), handle (5) is cylindrical, and all material adopts stainless steel to make.
