When it is rotated at the same time, it will drive the movement The gear plate 1 8 8 also rotates the rotating gear I of the rotating shaft 184b of the potentiometer 184, and drives the value. In addition, when the gear measures the relative side rotation angle center, and the gear plate 188 > The second rotation 8 cannot be kept the same as the first rotation shaft 172, which can avoid the ρ ^ shou of the rotation shaft of the potentiometer. The rotation plate 183 and the spring 189 are converted by the resistance value. The double angle is 5 and the output angle is 19 ◦Then use the 'X' test to say that the first yoke structure 17 ° also includes the rotation angle of the vertical protractor ir92. The vertical protractor 19 includes two fixed two 192, a positioner 194, and two elastic glue 196. The two fixed cry It is fixed on the inner side of the shaft hole of the f third rotation shaft 176, as shown in the figure L. ^ Ξ potential 4 19 4 'When the body is fixed to the two holders 19 2 respectively, the two rotation shafts are kept concentric with the shaft holes. . The elastic shaft 1 96 ′ of the potentiometer 194 is coated with the elastic glue 1 96 ′. For example, Youli glue is tightly inserted into the shaft holes of the two third rotating shafts 176 > and fixed to the shafts of the two third rotating shafts 176 with bolts. Inside the hole. One of the potentiometers of the vertical protractor 910, 94 rotates with the hip section 134 / special motion ', and the other potentiometer 194 of the vertical protractor 190 rotates with the back section 132. Therefore, the longitudinal protractor 190 can measure the rotation angles of the hip section 134 and the back section 132 with respect to the yoke structure 170 individually. Generally speaking, the angle of 'round out' is converted by the resistance value. Referring to Figure 6 of the figure, the structure 170 also includes a cover 202 to prevent blood or water generated during the operation from entering the operating table. The yoke cover
