Abstract

A dual-purpose spanner comprises a spanner handle, the front end of the spanner handle is a movable spanner head, the movable spanner head and the spanner handle are an integral structure, a bolt hole is arranged on the tail end of the spanner handle, the bolt hole is of a regular hexagon shape. The dual-purpose spanner of the utility model is improved and machined on the basis of the original common spanner, the structure is skillful, the working procedure is simple, the weight is light, the occupation space is small, the carrying is convenient, the operation is easy.

Description

A kind of combination wrenches

Technical field

The utility model relates to a kind of hand tools, is specifically related to a kind of combination wrenches.

Background technology

In industries such as machinery, weaving, maintenance, the spanner that is used for the installation or removal bolt has multiple pattern, as box spanner, double offset ring spanner etc., the spanner of these types designs corresponding model respectively at dissimilar bolts, function ratio is more single, when as needs four jiaos and hex bolts being installed, operates with regard to needing two kinds of spanners at least, this spanner has increased operation, is unfavorable for operation.

Because the common wrench 26S Proteasome Structure and Function is more single, existing have many products that the function of spanner is improved and made up at present, and its pattern is variation more, and function also further is expanded, and multi-functional product more and more receives an acclaim.But many multi-functional spanners owing to increased a large amount of improvement, have added new function, and its structure also becomes and becomes increasingly complex, and weight is also more and more heavier, and it is big to take up room, and are unfavorable for carrying, and are also inconvenient during use.

The utility model content

At spanner of the prior art have simple in structure, function is too single, the increase that has function but increased also that volume, weight increase the weight of, deficiency that price is also relatively more expensive, the utility model provide a kind of easy to use, in light weight, combination wrenches little and that cost is low takes up room.

The technical solution of the utility model is achieved in that a kind of combination wrenches, comprises the spanner handle, the front end of spanner handle be Flexible spanner at hand, Flexible spanner at hand with spanner being integral structure, it is characterized in that: the tail end at the spanner handle is provided with bolt hole.

Further technical characterictic, the bolt hole that described combination wrenches is set, it is shaped as regular hexagon.

With respect to prior art, the utlity model has following advantage:

1, directly improve processing on original common wrench and get final product, structure is ingenious, and operation is simple, helps manufacturing;

2, spanner is in light weight, and it is little to take up room, and is convenient for carrying, also lighter during operation;

3, increase the function of a back-up wrench, the circular hole on original spanner can have been changed system into the combination wrenches of multiple different model, can satisfy the demand of different model bolt.

Description of drawings

Fig. 1 is the structural representation of the utility model combination wrenches;

Wherein, 1-spanner handle, 2-Flexible spanner at hand, the 3-bolt hole.

The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Combination wrenches of the present utility model comprises spanner 1, and spanner is 1 front end a Flexible spanner at hand 2, Flexible spanner at hand 2 with spanner be 1 integral structure, common employing is made as the integral structure of one: at spanner 1 tail end is provided with bolt hole 3.

The bolt hole 3 that described combination wrenches is set, it is shaped as regular hexagon.Bolt hole 3 also can be set to square or other shapes according to the model of different bolts, and the diameter in its hole also can be made into different sizes, to satisfy the demand of various model bolt heads or nut.

Combination wrenches of the present utility model is to improve to form on the structure of monkey wrench commonly used.Tail end at monkey wrench handle commonly used leaves a circular hole usually, and this hole does not have special function, and on the basis of this finished product monkey wrench, the utility model has carried out structural improvement to this.With spanner the circular hole of 1 tail end, by processing modes such as punching presses, change system into and bolt head or the corresponding bolt hole 3 of nut shape, bolt hole 3 can be positive hexagon ring, it also can be the hole of four jiaos or other shapes, the diameter of bolt hole 3 can be made into different sizes respectively, satisfies the demand of various bolt heads and nut with this.

Claims

1, a kind of combination wrenches comprises that spanner (1), is Flexible spanner (2) at hand at spanner to the front end of (1), and Flexible spanner (2) at hand is (1) integral structure with spanner, and it is characterized in that: described spanner is provided with bolt hole (3) to the tail end of (1).

2, combination wrenches according to claim 1 is characterized in that: described bolt hole (3), it is shaped as regular hexagon.

3, combination wrenches according to claim 1 is characterized in that: described bolt hole (3), it is shaped as square.
