Embodiment
Shown in the three-dimensional exploded view of Fig. 1 the utility model preferred embodiment, this positioning joint is combined by frame (1), inner housing (2), locking knob (3), rotating shaft (4), tapered end (5), automatic positioning head (6) and spring (7);
Wherein inner housing (2) Lower Half is assembled in the frame (1), and locking knob (3) lower set is loaded in the inner housing (2), and above-mentioned three parts combination back is snapped together by rotating shaft (4);
Frame (1) upper, annular is arranged with 24 locking pits (8), 8 tapered ends of inner housing (2) annular array are by hole (9), 8 tapered ends of locking knob (3) annular array are kept away position depression (10), by rotational lock knob (3), change tapered end and keep away the position of position depression (10), joints open when making tapered end (5) and locking pit (8) joint locking, tapered end (5) entering tapered end and keep away the position and cave in (10) when matching;
Frame (1) lower annular is arranged 24 location pits (12) and is matched with 2 automatic positioning heads (6), inner housing (2) has 2 spring mounting holes (11) to be used for mounting spring (7), can locate automatically when making rotation case body (1) arrive locked position with inner housing (2); Restraining groove (14) on the inner housing (2) matches with spacing salient point (13) on the locking knob (3), and the rotating range that limits locking knob (3) is about 22.5 degree;
The rotatable handle (19) of lengthening makes the laborsaving convenience that operates; Sense of rotation indicating arrow (18) and on off state literal indication (17) are in order to locking that indicates the joint and the sense of rotation of unclamping;
Frame (1) is gone up 24 and the corresponding calibration points of locking pit (8) (15) of annular array, inner housing (2) is gone up and tapered end passes through the corresponding positioning index dot in hole (9) (16), align when reaching locked position with inner housing (2) at frame (1), make the operation intuitive and convenient.
As Fig. 2, Fig. 3, Fig. 4, Fig. 5, shown in Figure 6, planimetric map and sectional view for the utility model preferred embodiment rotational position 1, frame this moment (1) is that 180 degree, locking knob (3) are in unlocked position (spacing salient point (13) is positioned at the left end of restraining groove (14)) with inner housing (2) relative angle, tapered end is kept away position depression (10) and is aimed at tapered end (5), automatically positioning head (6) is positioned at location pit (12), and spring (7) is in elongation state.
