Abstract

The utility model provides a double-head monkey wrench. The double-head monkey wrench comprises a wrench main body; a wrench head is arranged at each of the two ends of the wrench main body; the wrench heads are respectively hinged with the wrench main body through positioning pins; and the positioning pins are detachably connected with the wrench main body. After the wrench heads are respectively hinged with the wrench main body, the angles among the wrench main body and the wrench heads are adjusted as required; therefore, the requirement for use in various complicated operating environments can be satisfied; and, as the positioning pins are detachably connected with the wrench main body, different wrench heads can be changed as required, when the double-head monkey wrench is used, only various wrench heads are carried and the carrying of various wrenches is unnecessary. Therefore, the double-head monkey wrench provided by the utility model is convenient to carry; and compared with the traditional double-head wrench, the range of use and the occasion of application of the double-head monkey wrench are greatly increased.

Description

A double end spanner alive

Technical field

The utility model relates to a kind of instrument, is a kind of double end spanner alive specifically.

Background technology

Spanner is a kind ofly to be used for fastening or to unscrew the instrument of bolt, nut or similar workpiece; Usually be shaped on the trepanning of fixed dimension and shape (like pentagon, hexagon, octagon etc.) in the one or both ends of its shank, in order to the nut or the bolt of twisting this size and dimension.But the workmen does not often know the size and dimension of nut, bolt in advance when carrying out operation, and this just need carry very inconvenient with the spanner of going up various sizes and shape trepanning.In addition, this spanner is when acting on bolt or the nut that is positioned at narrow and small or depression depths, space, and relatively difficulty operates also.

The utility model content

The utility model technical problem to be solved is to provide a kind of and be suitable under various operating environments, using and a double end spanner alive easy to carry.

For solving the problems of the technologies described above; The double end that the utility model a provides spanner alive comprises wrench body, and the two ends of described wrench body are equipped with driving end; Described driving end is hinged through alignment pin and wrench body respectively, and described alignment pin is connected with wrench body is removable.

Described driving end can rotate in 180 ° of scopes around alignment pin.

The size and dimension of the driving end at said wrench body two ends is all identical.

The driving end at described wrench body two ends is five jiaos of measure-alike driving ends.

The size of the driving end at said wrench body two ends is or/and shape is all different.

After adopting above structure, the utility model double end is lived a spanner compared with prior art, has the following advantages:

After driving end and wrench body are hinged, adjust the angle of wrench body and driving end as required, can satisfy the demand of in various complicated operations environment, using; And, because alignment pin is removable the connection with wrench body, therefore; Change different driving ends according to demand, only need carry various driving ends during use and get final product, need not to carry whole spanner; Therefore; Carrying of the double end of a utility model spanner alive is comparatively convenient, and than the double (end) wrench of routine, its scope of application and application scenario all are greatly improved.

The specific embodiment

Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.

Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, identical with other spanners, the utility model double end spanner alive also comprises wrench body 1, is equipped with driving end 2 at the two ends of wrench body 1.Driving end is pulled wrench body 1 and just can be operated bolt with after bolt cooperates.

The difference of the utility model double end spanner alive and conventional spanner is: in the utility model; The driving end 2 at its wrench body 1 two ends is rotary; And for the ease of carrying, driving end 2 also can be from wrench body 1 dismounting; Concrete technical scheme is: driving end 2 is hinged through alignment pin 3 and wrench body 1 respectively, alignment pin 3 and 1 removable connection of wrench body.The rotation of driving end 2 between alignment pin 3 realizations and wrench body 1, removable alignment pin 3 has realized that then driving end 2 is demountable.

As some concrete corrective measures, driving end 2 can rotate in 180 ° of scopes around alignment pin 3.Certainly, also can be as required, the rotational angle of driving end 2 also can be above 180 °.

In the utility model, as shown in Figure 1, the size and dimension of the driving end 2 at wrench body 1 two ends can be all identical, such as: the driving end at wrench body 1 two ends is five jiaos of measure-alike driving ends.

Certainly, as shown in Figure 2, the size of the driving end 2 at wrench body 1 two ends be or/and shape also can be all different, such as: the driving end at wrench body 1 two ends is respectively five jiaos of driving ends and die nut head.

Claims

1. a double end spanner of living; Comprise wrench body (1); The two ends of described wrench body (1) are equipped with driving end (2), it is characterized in that: described driving end (2) is hinged through alignment pin (3) and wrench body (1) respectively, described alignment pin (3) and removable connection of wrench body (1).

2. a double end according to claim 1 spanner alive, it is characterized in that: described driving end (2) can rotate in 180 ° of scopes around alignment pin (3).

3. a double end according to claim 1 spanner alive, it is characterized in that: the size and dimension of the driving end (2) at said wrench body (1) two ends is all identical.
