54, horizontal drive shaft 55, and then drive elevating lever 56 that rotation support plate 6 and rotating platform 7 is driven to go up and down, as shown in Figure 2, Figure 4 shows.
The rotating electric machine 71 of rotating platform 7 drives turntable 73 to rotate, and then drives the C-arm support of 7 top of rotating platform
Plate 8 and C-arm device 9 are using vertical center line as axis rotation, as shown in Figure 5.
First arc 91 is two arcs being parallel to each other, and two arcs are connected on column 93 by swing mechanism 94, the second arc
92 are arranged between two first arcs 91, and can be with the opposite sliding of the first arc 91, it may be assumed that gear 901 and 914 phase of the first rack gear
Mutually engagement, servo motor 902 drive the axial rotation of the first arc 91, and gear 901 and the second rack gear 924 are intermeshed, servo motor
The axial rotation of 902 the second arc of driving 92, as shown in Figure 3.The patent of invention of authorization, i.e. documents are obtained with reference to the applicant
CN106175917A, " axis is overlapped with the central axis of beam-defining clipper, radiographic source, reception device.The B arc is for guiding into nail
Direction, A arc prevent too deep into following closely；A arc, B arc include the i.e. integrated bulb of arrangement for perspective and beam-defining clipper, Imaging enhanced at its both ends
Device." the first arc of the application 91 and integrated bulb, beam-defining clipper, the image amplifier on the second arc 92 distinguish coaxial line, and two
Axis Cross forms angle, convenient for auxiliary pedicle nail merging.In clinical application, two axial lines angle is just at 15 ° or so
In the best angle that pedicle nail is positioned and is placed in, therefore the angle that the first arc 91 and the second arc 92 respectively can be rotated axially is not
Must be excessive, 0 ° -70 ° of angular range is best.
943 left end of swinging axle of swing mechanism 94 connects the first arc 91, and right end connection swings retarder 942, swings and slow down
