With the adoption of the technical scheme, the arm of the wrench is formed by connecting the first sub arm and the second sub arm which are mutually hinged; and meanwhile, the first sub arm and the second sub arm are positioned by using the positioning devices, so that the length of the wrench can be selected according to actual demands during use. Therefore, the wrench is labor-saving and convenient to use.

Description

A kind of spanner

Technical field

The utility model relates to a kind of spanner.

Background technology

Spanner is common a kind of instrument in daily life and the production, and at present, in mould handling, the arm length of spanner is generally fixed, and this can be with aborning and serve inconvenience.As: the arm of spanner is too short, not only uses inconvenience in some occasion, in use needs the very large strength of expense just can pull the parts such as nut simultaneously; If the arm of spanner is long, may be relatively laborsaving, but when carrying and take in, also have inconvenience.

The utility model content

The purpose of this utility model is to provide a kind of spanner, and this spanner is laborsaving and easy to use.

For achieving the above object, the utility model has adopted following technical scheme: the arm of described spanner comprises first, second minute arm that sets gradually, described first, second minute, the junction of arm linked to each other by rotating shaft, and first, second minute arm be provided with positioner.

Positioner of the present utility model comprises the latch that is separately positioned on first, second locating hole on first, second minute arm and matches with first, second locating hole, described latch comprises bottom bar, the two ends of bottom bar are provided with two side rods perpendicular to bottom bar, and described two side rods insert respectively in first, second locating hole.

First, second locating hole of the present utility model arranges respectively two.

The length of second minute of the present utility model arm slightly is shorter than the length of first minute arm.

As shown from the above technical solution, the utility model is linked to each other by first, second minute arm that is hinged by the arm with spanner and forms, simultaneously with positioner come to first, second minute arm position, in use can select according to actual needs the length of spanner, make spanner use laborsaving and convenience.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the structural representation of the utility model latch.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further:

A kind of spanner as shown in Figure 1, the arm of spanner comprise set gradually first, arm 1 in second minute, 2, first, arm 1 in second minute, 2 junction links to each other by rotating shaft 3, and first, arm 1 in second minute, 2 are provided with positioner, specifically, positioner comprises and is separately positioned on first, arm 1 in second minute, on 2 first, the second locating hole 4,5 and with first, the second locating hole 4,5 latches that match 6, latch 6 comprises bottom bar 61, the two ends of bottom bar 61 are provided with two side rods 62 perpendicular to bottom bar 61, two side rods 62 insert respectively first, the second locating hole 4, in 5, be used for fixing first, arm 1 in second minute, 2, it is not in use rotated.As preferred version of the present utility model, first, second locating hole 4,5 arranges respectively two, like this location reliability higher, when using simultaneously first, second minute arm 1,2 junctions intensity also larger.As preferred scheme, the length of second minute arm 2 slightly is shorter than the length of first minute arm 1, is in order to interfere with Wrench head like this.When normal the use, first, second minute, arm 1,2 overlaped, when needing the arm of Lengthened wrench, with arm 2 rotations in second minute to the position equal with first minute arm 1, and be fixed in first, second locating hole 4,5 with latch 6, realize that positioning instant can use.

Above-described embodiment is described preferred embodiment of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
