Embodiment

The present invention utilizes the magnetic ability to eliminate the preferred embodiment of turning shaft structure in gap such as Fig. 2 to shown in Figure 4, comprises:

One pedestal 20 has an accommodating recess 21;

One counterpart 30 is shaped and is placed in the accommodating recess 21 of this pedestal 20 profile that should accommodating recess 21, and this counterpart 30 of the present embodiment has an auxiliary section 31 that is the recessed structure of arc;

One rotating shaft piece 40, formed by a rotating component 41 and an axostylus axostyle 42, the rotating component 41 of the present embodiment is ball head structure, rotating component 41 correspondences of this rotating shaft piece 40 are placed in the auxiliary section 31 of this counterpart 30, this rotating shaft piece 40 is combined with these counterpart 30 magnetic and can be relatively rotated, the counterpart 30 of the present embodiment has the magnetic ability, and this rotating shaft piece 40 is can be made by the material of magnetic, certainly, also replaceable have the magnetic ability for this rotating shaft piece 40, and this counterpart 30 is can be made by the material of magnetic, also can reach identical purpose; This axostylus axostyle 42 is provided with linking with the assembly that is used in conjunction with, for example manipulator.

More than for utilizing the magnetic ability, the present invention eliminates the structural relation of the turning shaft structure in gap, rotating component 41 by sphere cooperates corresponding auxiliary section 31, make this rotating shaft piece 40 that the action of universal rotational can be provided, and the axostylus axostyle 42 of this rotating shaft piece 40 is not subject to again placing restrictions on of other members, therefore can improve again the degrees of freedom of rotation;

And the present invention is combined with the active magnetic of 40 of this rotating shaft pieces by counterpart 30, this counterpart 30 is provided with the rotation except the auxiliary section 31 that cooperates rotating component 41 is set, active absorption between this counterpart 30 and this rotating shaft piece 40, can eliminate the gap between rotating shaft piece 40 and this counterpart 30 fully, and when this rotating shaft piece 40 cooperates the member that needs high-accuracy displacement to use, just can avoid the generation of error fully, improve it and use applicability; Simultaneously, therefore the present invention does not more need the extra member of placing restrictions on or locating by the counterpart 30 that can initiatively adsorb rotating shaft piece 40 is set, and integrated member is very simple, can significantly reduce the assembling production cost, increases economic efficiency.

In addition, for further guaranteeing interstructural combination stability, more a protecting cover 50 can be set again, this protecting cover 50 has a through hole 51, this protecting cover 50 is fixedly installed on this pedestal 20 and covers this accommodating recess 21, and makes the axostylus axostyle 42 of this rotating shaft piece 40 be stretched out the action that the axostylus axostyle 42 that is then stretched out by through hole 51 can rotate equally by this through hole 51, this protecting cover 50 can guarantee that then this rotating shaft piece 40 and this counterpart 30 place restrictions in this accommodating recess 21, guarantees the stability of structure.

Moreover 40 active magnetic of the counterpart 30 of above-described embodiment and this rotating shaft piece are combined, and need to arrange in addition to place restrictions on or member that the block rotating shaft piece is deviate from, and this counterpart 30 abut against this rotating shaft piece 40 and can reach as long as can cooperate; Certainly also can be as shown in Figure 4, the auxiliary section 31 of this counterpart 30 is configured as can be coated to the form of this rotating shaft piece 40 rotating components 41 greater than 1/2nd areas, so again so that this counterpart 30 except adsorbing this rotating shaft piece 40, this counterpart 30 itself also can be brought into play the effect of placing restrictions on, and further guarantees the stability of structure.

The pedestal 20 of above-described embodiment all is provided with accommodating recess 21 with accommodating this counterpart 30, certainly also can be as shown in Figure 5, accommodating recess 21 is not set on this pedestal 20, and this counterpart 30 is to fit or other affixed means are fixed on this pedestal 20 and also can reach the purpose identical with the various embodiments described above and effect.

As shown in Figure 6, the auxiliary section 31 of this counterpart 30 can be configured as ball head structure, this counterpart 30 is directly fixed on this pedestal 20, the rotating component 41 of this rotating shaft piece 40 then has the recessed structure of arc that cooperates this auxiliary section 31 to be shaped, and the displacement of structure configuration also can be reached and above-mentioned identical purpose by this.

Below through the specific embodiment and the embodiment the present invention is had been described in detail, but these are not to be construed as limiting the invention.In the situation that do not break away from the principle of the invention, those skilled in the art also can make many distortion and improvement, and these also should be considered as protection scope of the present invention.
