Compared with the prior art, the joint has the advantages that the male connecting part and the female connecting part are in rotational connection, so that the joint can change the force transmission direction according to actual requirements in the using process.

Description

Joint
Technical field
The utility model relates to a kind of manual or pneumatic tool, particularly relates to a kind of joint.
Background technology
In various pneumatic and hand-operated tools, often need to use joint, to play the effect of connection and the power of transmission, above-mentioned joint generally comprises male connecting portion and female connecting portion, the female connecting portion can be used for fixing screwdriver bit, screwdriver bit is connected with securing member, the male connecting portion generally is connected with sleeve, then sleeve is connected with force arm, when external force is applied on the force arm, by sleeve, male connecting portion, female connecting portion power is passed to screwdriver bit, last screwdriver bit is applied to power on the securing member, is connected on the thing thereby securing member is fastened on.
Some pneumatic tool and hand-operated tools are in use, the environment more complicated, in the auto repair process, the space of leaving operating personnel and maintenance tool for can be restricted, and in the existing joint, for being fixedly connected with, can not change the direction of transfer of power between male connecting portion and the female connecting portion, therefore use the defective that can have inconvenience.
The utility model content
Technical problem to be solved in the utility model is to provide the joint that can change the direction of transfer of power in a kind of use procedure for above-mentioned prior art.
The utility model solves the problems of the technologies described above the technical scheme that adopts: this joint, comprise male connecting portion and female connecting portion, it is characterized in that: between described male connecting portion and the described female connecting portion for being rotationally connected.
Rotation connection structure between male connecting portion and the female connecting portion can be realized in the following way: a side of described female connecting portion has U-shaped groove, the corresponding side of described male connecting portion has a U-shaped opening, be provided with a connecting axle between male connecting portion and the female connecting portion in addition, the first end of this connecting axle rotates by the first rotating shaft and is arranged in the described U-shaped groove, and the second end of described connecting axle rotates by the second rotating shaft and is arranged in the described U-shaped opening.
As improvement, the axial vertical interlaced setting of axial and described second rotating shaft of described the first rotating shaft.Male connecting portion and female connecting portion can change the direction of transfer of power in 360 degree scopes like this.
Compared with prior art, the utility model has the advantage of: by being set to be rotationally connected between male connecting portion and the female connecting portion, joint in use can change the direction of transfer of power according to actual needs like this.
