Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is that the present invention three grabs the schematic diagram that the stationary installation of pedestal is connected with three-jaw pedestal.
The implication of Reference numeral in figure:
0-three-jaw pedestal, 10-central rotation post, 11-first paragraph cylinder, 12-second segment cylinder, the 3rd section of cylinder of 13-, 20-external stability ring, 21-circular base, 22-annular retractable part.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
Three stationary installations of grabbing pedestal as shown in Figure 1, comprise fixed leg, and fixed leg comprises: central rotation post 10 and external stability ring 20, and central rotation post 10 is rotatably connected with external stability ring 20; External stability ring 20 comprises: circular base 21, the annular retractable part 22 being fixedly connected with circular base 21; The internal diameter of circular base 21 equals the internal diameter of annular retractable part 22; Central rotation post 10 is positioned at the inner side of external stability ring 20, central rotation post 10 comprises: end to end first paragraph cylinder 11, second segment cylinder 12, the 3rd section of cylinder 13, second segment cylinder 12 is positioned at external stability ring 20, and first paragraph cylinder 11 and the 3rd section of cylinder 13 are positioned at the outside, two ends of external stability ring 20.
The periphery of circular base 21 is provided with the first screw thread, and the first screw thread covers the outer wall of circular base 21 comprehensively.The through-hole wall of three-jaw pedestal is provided with the second screw thread with the first threaded engagement, and the second screw thread is positioned at the top of the through hole of three-jaw pedestal, and the axial length that second segment cylinder 12 is provided with the position of the second screw thread equals the axial length of circular base 21.The first screw thread, the second screw thread cooperatively interact, and such being threaded is more firm.First paragraph cylinder 11 sidewalls are provided with through hole, are convenient to staff and grip rotation center column spinner 10, are also convenient to collect central rotation post 10 by through hole.
The diameter of first paragraph cylinder 11 is greater than the diameter of the 3rd section of cylinder 13, and the diameter of the 3rd section of cylinder 13 is greater than the diameter of second segment cylinder 12.The poor formation stage portion of diameter of the 3rd section of cylinder 13 and second segment cylinder 12, annular retractable part 22 is located in this stage portion.The external diameter of circular base 21 is greater than the external diameter of annular retractable part 22, and the diameter of first paragraph cylinder 11 equals the external diameter of circular base 21, and the diameter of second segment cylinder 12 equals the internal diameter of circular base, and the diameter of the 3rd section of cylinder 13 equals the external diameter of annular retractable part 33.As shown in Figure 2, when installation, second segment cylinder 12 and the 3rd section of cylinder 13 are inserted in the mounting hole of three-jaw pedestal 0 (first paragraph cylinder is placed in the below of three-jaw pedestal), the mounting hole of three-jaw pedestal 0 is and circular base 21, the step that annular retractable part 22 coordinates, the circular base 21 of second segment cylinder 12 is fixed by internal and external threads with mounting hole like this, now circular base 21 is fixedly connected with three-jaw pedestal 0, hand-held first paragraph cylinder 11 is to the direction rotation away from the 3rd section of cylinder 13, because first paragraph cylinder 11, second segment cylinder 12, the 3rd section of cylinder 13 is integrally formed, whole central rotation post 10 is upwards mentioned, the 3rd section of cylinder 13 impels annular retractable part 22 in axle generation deformation, outwardly convex, increase like this pressure of the mounting hole inwall of annular retractable part 22 to three-jaw pedestal, stationary installation and the three-jaw pedestal of three-jaw pedestal of the present utility model are fixed together tightly, the axial length sum of circular base 21 and annular retractable part 22 equals the thickness of three-jaw pedestal, the surface area maximum that stationary annular extensible member 22 contacts with the mounting hole inwall of three-jaw pedestal like this, fixing the most firm.
