The movement to limit described adaptor for the matching used described nut of axle head, described adaptor is threaded connection and turns described
Auricle is installed in the described body other end.
Preferably, described the described circular shaft end of transfer ear piece can be socketed with packing ring, described packing ring be located at described adaptor with
Between described nut.
Preferably, described axis hole gap engagement sleeves can be passed through with the endoporus of described adaptor in the described circular shaft end of transfer ear piece
Dress.
Preferably, the hand of spiral that described body is threaded connection with described fixing auricle, described body with described
The hand of spiral that adaptor is threaded connection, two hand of spirals are contrary.
Preferably, described fixing auricle can transfer ear piece, described adaptor, described nut can be replaced by described.
A kind of having the beneficial effects that of adjustable drawbar with axial rotation degree of freedom provided by the utility model, realizes
Pull bar, around the rotation of 360 degree of axis, can carry out bar length regulation as needed after pull bar is installed in place simultaneously, and can pass
Pass larger Tensile or Compressive Loading.

Specific embodiment
For making purpose, technical scheme and advantage that this utility model is implemented clearer, below in conjunction with this utility model
Accompanying drawing in embodiment, is further described in more detail to the technical scheme in this utility model embodiment.In the accompanying drawings, ad initio
To the element that same or similar label represents same or similar element or has same or like function eventually.Described reality
Applying example is a part of embodiment of the present invention, rather than whole embodiments.Embodiment below with reference to Description of Drawings is to show
Example property it is intended to be used for explaining this utility model, and it is not intended that to restriction of the present utility model.Based in this utility model
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of not making creative work,
Broadly fall into the scope of this utility model protection.
The adjustable drawbar to this utility model below in conjunction with the accompanying drawings with axial rotation degree of freedom is described in further details.
As depicted in figs. 1 and 2, a kind of adjustable drawbar with axial rotation degree of freedom, including body 5 and fixing auricle 6,
Fixing auricle 6 is socketed in the inside of body 5 one end by screw thread, also include can transfer ear piece 1, adaptor 2, nut 4, can transfer ear piece
1 is made up of, at circular shaft end 11 near auricle end 12 side edge with the auricle end 12 that is connected with this cylindrical end 11 side circular shaft end 11
Radial direction setting one circle annular flange 111, as shown in Fig. 2 or Fig. 3.The circular shaft end 11 of transfer ear piece 1 will can be sleeved on switching
2 interior in the hole, prioritizing selection axis hole gap cooperation suit, realize can mutual rotation between transfer ear piece 1 and adaptor, that is, realize
Pull bar of the present utility model is around 360 degree of rotations of own axes, then will be transferred by screwing the matching used nut 4 with circular shaft end 11
2 are fixed on to come between flange 111 and nut 4, flange 111 and both nuts 4 limit can transfer ear piece 1 with respect to adaptor 2
Axial movement, it is to avoid the play of adaptor 2.Can also may be used between adaptor 2 on transfer ear piece 1 circular shaft end 11 and nut 4
Select socket packing ring 3, this packing ring 3 can alleviate the CONTACT WITH FRICTION between adaptor 2 and nut 4, extend each service life, such as scheme
Shown in 3.Adaptor 2 is threaded connection and can transfer ear piece 1 be installed in described body 5 other end, this thread rotary orientation and pipe
Thread rotary orientation between body 5 and fixing auricle 6 is contrary, that is, one be left-handed be dextrorotation to being fixed by quick regulation to another
The length of auricle 6 precession body 5 and regulation can adjust this utility model by the length of adaptor 2 precession body 5 by transfer ear piece 1
Pull bar overall length, can transmit compared with big load simultaneously again.
Body 5 two ends all can using can transfer ear piece 1 be socketed in inside adaptor 2, screw with can transfer ear piece 1 matching used
Nut 4, the form that then adaptor 2 outer wall is connected with body 5 by screw thread, realize two ends auricle all around 360 degree of own axes
Rotate.
The above, specific embodiment only of the present utility model, but protection domain of the present utility model does not limit to
In this, any those familiar with the art in the technical scope that this utility model discloses, the change that can readily occur in
Change or replace, all should cover within protection domain of the present utility model.Therefore, protection domain of the present utility model should be with described
