Abstract

The utility model discloses a kind of wrench assembly for piano tuning, including handle, swivel head, gear-box and spanner set, the handle base connects swivel head, the swivel head lower end tooth connection roller box, be equipped in the gear-box master gear and from gear one, from gear two, described to be fixedly mounted in gear-box from gear one and from gear two, the gear-box lower end connects spanner set；The phenomenon that the structure design of the utility model is reasonable, facilitates operation, increases micromatic setting, reduces spanner toning, while spanner set can choose the different wrench head of connection and spanner set can be with voluntary activity, therefore is suitable for the piano maintenance of different size.

Description

A kind of wrench assembly for piano tuning

Technical field

The utility model relates to a kind of wrench assembly more particularly to a kind of wrench assemblies for piano tuning.

Background technique

Piano tuning wrench is the indispensable tool in piano maintenance, and traditional piano tuning wrench is fixed wrench head, The string for repairing different pianos needs different tools, caused in carrying process it is many it is constant just, while traditional temperament is pulled Hand can cause to miss standard pronunciation when adjustment when adjusting regular movements because strength is excessive, once this problem occur must be back It adjusts, reduces tuning speed.

Utility model content

The purpose of the utility model is to provide a kind of piano tuning wrench components reasonable in design, easy to operate.

Purpose of the utility model is realized as follows: a kind of wrench assembly for piano tuning, including handle, rotation Head, gear-box and spanner set, the handle base connect swivel head, the swivel head lower end tooth connection roller box, the gear-box It is interior be equipped with master gear and from gear one, from gear two, described to be fixedly mounted in gear-box from gear one and from gear two, institute State gear-box lower end connection spanner set.

As the further preferred scheme of the utility model, the handle is divided into handle front end and handle rear end, the hand Tooth tooth-like recesses are equipped with and the placement that is staggered on the inside of handle front end outer side and handle rear end.

As the further preferred scheme of the utility model, it is equipped with steel ball in the handle rear end, which can freely revolve Turn.

As the further preferred scheme of the utility model, the swivel head is connected on steel ball.

As the further preferred scheme of the utility model, the handle front end and handle rear end junction are equipped with sliding block, Push sliding block that can pull open handle front end and handle rear end.

As the further preferred scheme of the utility model, the swivel head lower end is fixedly connected on master gear, main tooth Motion transmission is taken turns to move from gear one, from gear two.

As the further preferred scheme of the utility model, the spanner set is connected to from gear one, from gear two.

Compared with prior art, the utility model has the advantage that as follows: the structure design of the utility model is reasonable, side Portable belt uses；Since handle is provided with two parts, and with tooth tooth-like recesses and the placement that is staggered, such knot between two parts Structure design facilitates to space out between handle front end and handle rear end, that is, changes the total length of handle, laborsaving in maintenance process； Swivel head is connected since steel ball being arranged in handle base, such structure is similar to universal wheel, so that swivel head can arbitrarily revolve Gyration arbitrarily changes orientation angle in maintenance process；Since gear-box is arranged, mutual cooperation between several gears makes It every must rotate, the wrench head in spanner set can accurate move angle.

Detailed description of the invention

It, below will be in embodiment technical description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model Required attached drawing does simple introduction, it should be apparent that, the accompanying drawings in the following description is only the one of the utility model A little embodiments for those of ordinary skill in the art without creative efforts, can also be according to these Attached drawing obtains other attached drawings.

FIG. 1 is a schematic structural view of the utility model.

Fig. 2 is A enlarged drawing.

Wherein, 1- handle: 11- handle front end, 12- handle rear end, 2- swivel head, 3- gear-box, 4- spanner set, 5- is from tooth One, 6- master gear is taken turns, 7- is from gear two, 8- sliding block, 9- steel ball.

Specific embodiment

Below with reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out clear Chu is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole realities Apply example.Based on the embodiments of the present invention, those of ordinary skill in the art are not under the premise of making creativity labour All other embodiment obtained, belongs to the range of the protection of the utility model.

As shown in Figs. 1-2, a kind of wrench assembly for piano tuning, including handle 1, swivel head 2, gear-box 3 and pull Sub-set 4,1 bottom of handle connect swivel head 2, and the 2 lower end tooth connection roller box 3 of swivel head, the gear-box 3 is interior to be equipped with master Gear 6 and from gear 1, from gear 27, it is described to be fixedly mounted in gear-box 3 from gear 1 and from gear 27, it is described 3 lower end of gear-box connects spanner set 4.

Preferably, the handle 1 divides for handle front end 11 and handle rear end 12, behind 11 outside of handle front end and handle 12 inside of end is equipped with tooth tooth-like recesses and the placement that is staggered.

Preferably, it is equipped with steel ball 9 in the handle rear end 12, which is freely rotatable.

Preferably, the swivel head 2 is connected on steel ball 9.

Preferably, the handle front end 11 and 12 junction of handle rear end are equipped with sliding block 8, push sliding block 8 can will be before handle End 11 and handle rear end 12 pull open.

Preferably, 2 lower end of swivel head is fixedly connected on master gear 6,6 motion transmission of master gear from gear 1, from Gear 27 moves.

Preferably, the spanner set 4 is connected to from gear 1, from gear 27.

Embodiment one:

In use, with hand push movable slider 8, since handle front end 11 and handle rear end 12 are that tooth tooth-like recesses and being staggered are put It sets, such structure setting can be slided when by external force, i.e., the weight between changeable handle front end 11 and handle rear end 12 Folded area to make handle 1 elongated/short, and then changes in maintenance firmly size, that is, reaches labor-saving effect.

Embodiment two:

When in use, suitable wrench head will be installed on spanner set 4 to be used to repair corresponding piano, it, can in maintenance Arbitrarily to adjust, because 1 lower end of handle is provided with steel ball 9 and connects swivel head 2, it is similar to the structure of universal wheel in this way, subtracts significantly Lack in maintenance process because of the drawback of position inconvenience, has improved maintenance efficiency.

Above description is only a specific implementation of the present invention, but the protection scope of utility model is not limited to This, anyone skilled in the art within the technical scope disclosed by the utility model, the variation that can readily occur in or is replaced It changes, should all cover within the protection scope of utility model.
