Abstract

The utility model relates to an automatic telescopic spanner, which comprises a spanner and a sleeve, wherein the spanner consists of a spanner head and a handle, the bottom end of the sleeve is sealed, the handle of the spanner is inserted in the sleeve, in addition, the bottom of the handle is fixedly connected with the bottom of the sleeve through a spring a, two T-shaped clamp grooves are arranged on the handle and are positioned at the same side of the handle, a T-shaped clamp block is fixedly connected into the clamp groove near the bottom of the handle through a spring b, a position on the sleeve positioned, at the same side of the clamp grooves, is provided with a T-shaped fixing groove, the fixing groove and the clamp block have the corresponding size, a T-shaped control block is fixedly connected into the fixing groove through a spring c, the number of the clamp grooves is four, in addition, every two clamp grooves are in one group and are respectively positioned at two sides of the handle, and the length of the sleeve is smaller than the length of the handle. The automatic telescopic spanner disclosed by the utility model has the advantages that the spanner can be automatically ejected out when the handle of the spanner needs to be lengthened, the structure is simple, the operation is convenient, and the applicability of the spanner is improved.

Description

A kind of automatically flexible spanner

Technical field

The utility model relates to a kind of hardware & tools, and especially a kind of spanner belongs to the hardware & tools technical field.

Background technology

When installing and maintaining machinery, usually can use spanner, but spanner generally all is a regular length, for some bolts, nut etc., just very inconvenient in the operation in the machine depths.In addition, bolt or nut are too tight sometimes, need on spanner, overlap a sleeve, utilize lever principle just can turn on bolt or nut.But, all need get a plurality of corresponding sleeves in advance ready under such situation, so neither be convenient for carrying, also limited to the use of spanner.In addition, if the slip away phenomenon of spanner of sleeve, will appear with not being fixedly connected between the spanner in sleeve when operation.

The utility model content

The utility model purpose is the spanner that a kind of automatically retractable simple in structure, easy to carry is provided for the deficiency that overcomes prior art.

For achieving the above object, the technical scheme that the utility model adopts is: a kind of automatically flexible spanner, comprise spanner and sleeve, and said spanner is made up of spanner and handle; The bottom sealing of said sleeve; The handle of said spanner is inserted in the sleeve, and the handle bottom is fixedly connected through spring a with the cover tube bottom; Have two T shape draw-in grooves on the said handle, and two draw-in grooves all are positioned at the same side on the handle; Be fixedly connected with T shape fixture block through spring b in the said draw-in groove near the handle bottom; The same side that is positioned at draw-in groove on the said sleeve has T shape holddown groove; Said holddown groove is big or small corresponding with fixture block, and is fixedly connected with T shape controll block through spring c in the holddown groove.

Preferably, said draw-in groove is four, and per two be one group, lays respectively at the both sides of handle.

Preferably, the length of said sleeve is less than the length of handle.

Because the utilization of technique scheme, the utility model compared with prior art has advantage:

A kind of automatically flexible spanner of the utility model scheme when the handle of needs lengthening spanner, can eject spanner automatically, and it is simple in structure, and is easy to operate, has increased the applicability of spanner.

Description of drawings

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

Accompanying drawing 1 is the structural representation of the automatically flexible spanner of the utility model;

Accompanying drawing 2 is that the automatically flexible spanner of the utility model ejects the structural representation when using;

Accompanying drawing 3 is the enlarged drawing at A place in the accompanying drawing 1;

Wherein: 1, spanner; 2, spanner; 3, handle; 4, sleeve; 5, spring a; 6, draw-in groove; 7, spring b; 8, fixture block; 9, holddown groove; 10, controll block; 11, spring c.

The specific embodiment

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

Accompanying drawing 1-3 is the described a kind of automatically flexible spanner of the utility model, comprises spanner 1 and sleeve 4, and said spanner 1 is made up of spanner 2 and handle 3; The bottom sealing of said sleeve 4; The handle 3 of said spanner 1 is inserted in the sleeve 4, and handle 3 bottoms are fixedly connected through spring a5 with sleeve 4 bottoms; Have two T shape draw-in grooves 6 on the said handle 3, and two draw-in grooves 6 all are positioned at the same side on the handle 3; Be fixedly connected with T shape fixture block 8 through spring b7 in the said draw-in groove 6 near handle 3 bottoms; The same side that is positioned at draw-in groove 6 on the said sleeve 4 has T shape holddown groove 9; Said holddown groove 9 is big or small corresponding with fixture block 8, and is fixedly connected with T shape controll block 10 through spring c11 in the holddown groove 9; Said draw-in groove 6 is four, and per two be one group, lays respectively at the both sides of handle 3.

Because the utilization of technique scheme, the utility model compared with prior art has advantage:

A kind of automatically flexible spanner of the utility model scheme when the handle of needs lengthening spanner, can eject spanner automatically, and it is simple in structure, and is easy to operate, has increased the applicability of spanner.

Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
