Abstract
The invention discloses a wrench head which comprises a handle connecting portion and a driving head connecting portion. The driving head connecting portion is fixedly connected with the handle connecting portion, a positioning screw is arranged on a side surface of the handle connecting portion, the driving head connecting portion is of a hollow structure, a first clamping device and a second clamping device penetrate the driving head connecting portion and are detachably connected with the driving head connecting portion, and a driving head is detachably connected onto the clamping devices. The wrench head has the advantages that the wrench head can be connected with driving heads which have different shapes and different sizes, so that the manufacturing cost can be reduced; the driving head is small, and accordingly the wrench head is portable.
Description
Technical field
The present invention relates to a kind of driving end, or rather, is a kind of driving end of replaceable driving head.
Background technology
Torque spanner utilizes that lever principle can be dismantled very easily, assembling screw.The structure of torque spanner is varied, according to the field of using, also has different sizes and size discrimination.In using the process of torque spanner, careful engineering staff finds, original cast-in-block spanner is designed to the Novel socket wrench of replaceable driving end, not only saves from causing this, and carries convenient.
In present engineering is manufactured or in daily life, the torque spanner of replaceable driving end has obtained general popularization.But, we can find after existing torque spanner is scrutinized, the driving end structure of a lot of spanners is all substantially to think together, different places is the shape of driving head, produced like this driving end can increase because of the repeating to manufacture of same area unnecessary production cost, waste raw material.The tool box of a lot of driving ends of a traction is relatively heavy, not portable.
Summary of the invention
The present invention solves the existing technical problem of prior art, thereby provides a kind of manufacturing cost lower, carries driving end more easily.
Above-mentioned technical problem of the present invention is mainly solved by following technical proposals:
A kind of driving end, comprise one handle connecting portion and a driving head connecting portion being fixedly connected with described handle connecting portion, the side of described handle connecting portion is provided with a set screw, described driving head connecting portion is hollow structure, one first clamping device runs through described driving head connecting portion dismountable with described driving head connecting portion with one second clamping device and is connected, and a driving head is removably connected on described clamping device.
As preferred embodiment of the present invention, the first described clamping device and the second described clamping device are that high strength CF carbon fibre is made.
Because driving end of the present invention can connect difformity and big or small driving head, thereby saved manufacturing cost, the while is due to the small volume of driving head, more convenient carrying.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the perspective view of driving end of the present invention;
Fig. 2 is the perspective view of the driving end in Fig. 1, is now another visual angle;
Fig. 3 is the perspective view of the driving end in Fig. 1, and now driving head connects from other direction;
Fig. 4 is the perspective view of the driving end in Fig. 3, is now another visual angle;
the specific embodiment
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention are made to more explicit defining.
The invention provides a kind of basis that certainly causes lower, carry driving end more easily.
If Fig. 1 is to as shown in Fig. 4, a kind of driving end 1, comprise one handle connecting portion 2 and a driving head connecting portion 4 being fixedly connected with described handle connecting portion 2, the side of described handle connecting portion 2 is provided with a set screw 3, described driving head connecting portion 4 is hollow structure, one first clamping device 51 runs through described driving head connecting portion 4 dismountable with described driving head connecting portion 4 with one second clamping device 52 and is connected, and a driving head 53 is removably connected on described clamping device 52.
The first clamping device 51 described in this driving end and the second described clamping device 52 are made for high strength CF carbon fibre.
Driving end utilization of the present invention can be dismantled the structure of driving head, thereby greatly reduces manufacturing cost, and to carry more convenient simultaneously.
Below only with an embodiment, mentality of designing of the present invention is described, in the situation that system allows, the present invention can expand to external more functional module simultaneously, thereby expands to greatest extent its function.
The above, be only the specific embodiment of the present invention, but protection scope of the present invention is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
Claims (2)
1. a driving end (1), comprise one handle connecting portion (2) and a driving head connecting portion (4) being fixedly connected with described handle connecting portion (2), the side of described handle connecting portion (2) is provided with a set screw (3), it is characterized in that, described driving head connecting portion (4) is hollow structure, one first clamping device (51) runs through described driving head connecting portion (4) dismountable with described driving head connecting portion (4) with one second clamping device (52) and is connected, one driving head (53) is removably connected on described clamping device (52).
2. driving end according to claim 1 (1), described the first clamping device (51) and described the second clamping device (52) are made for high strength CF carbon fibre.
