Below in conjunction with specific embodiment and shown in accompanying drawing, the utility model is adopted De Ji Intraoperative means and effect, be described in further detail.Believe the purpose of this utility model, feature and characteristics, when can be thus one deeply and concrete understanding, yet shown in accompanying drawing only provide with reference to the usefulness of explanation, be not to be used for the utility model is limited.
See also Fig. 1 to shown in Figure 3, the utility model is a kind of coaxial quantitative micromatic setting, and it comprises a central shaft 1, knob 2 and big knob 3, slide block 4 and slide block 5, one sway braces 6, briquetting 7 and limited block 8, decorative panel 15.Central shaft 1 is in the center of coaxial quantitative micromatic setting, brace 6 wraps in central shaft 1 periphery, and slide block 4, slide block 5, briquetting 7 wrap in the periphery of brace 6, and knob 2 and big knob 3 wrap in slide block 4 and slide block 5 peripheries, limited block 8 is decorative panels 15 before limited block 8 at central shaft 1 foremost.
All be with through hole in slide block 4, the slide block 5, hole shape is identical with sway brace 6 protruding cylinder surface shapes, and size is greater than sway brace 6 protruding cylinder surfaces, all be enclosed within on sway brace 6 protruding cylinder surfaces, in case limited slip block rotates around sway brace, and can slide on sway brace simultaneously, its outside surface all is a flank of thread; Slide block 4, slide block 5 be the tyre thread all; Slide block 4 screws for screw thread with knob 2;
The band central through hole is to be enclosed within on the central shaft 1 in the sway brace 6, and its profile one end is a flank of thread, and it can be fixed on the sphere shell 14, and the other end is a protruding cylinder surface;
Briquetting 7 is with a center pit, is placed in outside the sway brace 6, and an end is a sphere, and its shape and size are corresponding with the shape and the size of sphere shell, and the other end is the plane, its full-size greater than two knob threaded hole sizes with to they the location;
The big other end of limited block 8 one ends is little, and the full-size of big end is greater than the full-size of knob 2 unthreaded holes, and the small end shape is corresponding with central shaft 1 endoporus, to be fixed in central shaft 1.
Fig. 4, the spheroid locking device comprises: coaxial quantitative micromatic setting and spheroid latch mechanism.
Coaxial quantitative micromatic setting, it comprises a central shaft 1, knob 2 and big knob 3, slide block 4 and slide block 5, one sway braces 6, briquetting 7 and limited block 8.Central shaft 1 is in the center of coaxial quantitative micromatic setting, and brace 6 wraps in central shaft 1 periphery, and slide block 4, slide block 5, briquetting 7 wrap in the periphery of brace 6, and knob 2 and big knob 3 wrap in slide block 4 and slide block 5 peripheries, and limited block 8 at central shaft 1 foremost.
The spheroid latch mechanism comprises latch segment 9, latch segment 10, crimping piece 11, ball and socket base 12, spheroid 13, sphere shell 14, spheroid 13 is at the center of ball and socket base 12, packing ring 16 is positioned at the top of ball and socket base 12, latch segment 9, latch segment 10 are positioned at the lower end position of crimping piece 11, and the outermost of spheroid locking machine is a sphere shell 14.Coaxial quantitative micromatic setting is connected with latch segment 10 with the latch segment 9 of spheroid latch mechanism by central shaft 1.
When central shaft 1 rotation, will drive latch segment 9 and latch segment 10 locking phases to or oppositely move, when latch segment 9 and latch segment 10 are mobile in opposite directions, crimping piece 11 and ball and socket base 12 can move down, interaction force between ball and socket base 12 and the spheroid 13 will reduce like this, its friction force also can reduce, so the coupling mechanism force of spheroid 13 also will reduce even be zero, when latch segment 9 and latch segment 10 reverse when mobile, crimping piece 11 and ball and socket base 12 will slowly move up, the power of 12 pairs of spheroids 13 of ball and socket base also just increases gradually, thereby spheroid is locked.
The realization of above-mentioned functions mainly reaches by rotary middle spindle 1, so the rotation of control center's axle 1 is with regard to the locking state of may command spheroid 13.And the utility model is to achieve the goal like this: sway brace 6 is fixed on the sphere shell 14, simultaneously can the briquetting on it 7 is fixing, briquetting 7 can maintain plane contact with knob 2 always, so knob 2 can not move towards briquetting 7, knob 2 other ends also have plane and big knob 3 to keep in touch, therefore knob 2 can not move towards an end of big knob 3, can only rotate.Same, big knob 3 can not move towards this end of knob 2, and the other end of big knob 3 can have maintenance face to contact with limited block 8, thus it can not moved to limited block 8 directions, can only rotate.And slide block 4 screws for screw thread with knob 2, but the endoporus of slide block 4 is placed on the protruding cylinder surface of sway brace 6, so it can not rotate, so slide block 4 will axially move along sway brace 6 when knob 2 rotates, in like manner, when big knob 3 rotated, slide block 5 also can axially move along sway brace 6.
Because distance is limited between two slide blocks, so the displacement between two slide blocks is also limited, so the rotation number of turns of central shaft 1 also is limited.When slide block is in the original position (as accompanying drawing 3), this moment, slide block 5 had maximum sliding stroke, but corresponding spheroid 13 coupling mechanism force variation range at this moment is also maximum.When the big knob 3 of rotation moves slide block 5 to compress its end face with slide block 4 surface of contact, the coupling mechanism force of spheroid 13 has just reached minimum, and will regulate this minimum value (transferring big), rotatable big knob 3, slide block 5 is moved to the direction away from slide block 4, when reaching desired a certain coupling mechanism force, rotary knob 2 makes slide block 4 move towards slide block 5 directions again, up to not rotating, after this, only otherwise turning knob 2, the minimum coupling mechanism force of spheroid 13 will be decided, and is again constant; When needing again to regulate minimum value (turning down), rotatable knob 2, the direction that slide block 4 is done away from slide block 5 moves up to knob 2 and can not rotate again, rotate big knob 3 then, slide block 5 is moved towards the direction of slide block 4, when reaching desired a certain coupling mechanism force, again rotary knob 2 slide block is moved to slide block 5 directions to 4 can not turn up to knob, after this need only no longer rotary knob 2, its minimum coupling mechanism force is just constant, and adjusting is finished.
As mentioned above, regulate as long as just can carry out coupling mechanism force easily with hand, and if rotary knob 2 not, its minimum coupling mechanism force just is decided to be that value, and will regulate, also available hand turning knob is regulated and get final product, has reached quantitatively and the purpose of adjusting.
Being the utility model preferred embodiment only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should belong to technology category of the present utility model.
