When the driven transmission shaft 205 and the active transmission shaft 206 rotate, they also drive The dynamic positioning wheel 507 and the eccentric wheel 401 rotate, so that the positioning groove 508 is engaged with the positioning block 509. At the same time, the eccentric wheel 401 rotates to drive the lifting block 402 to descend, so that the lifting block 402 pushes the horizontal sliding seat 404 and the lifting block 303 to the lowest point, so that the center and eccentric line of the eccentric wheel 401 are perpendicular to the bottom surface of the lifting block 402, avoiding the lifting block 402 from pushing back. At the same time, the roller groove 305 is engaged and locked with the rotating roller 112, so that the seat is positioned; When the upper rail system is damaged, the lower toggle plate 209 is pressed down, and the toggle plate 209 drives the active transmission shaft 206 to rotate, and the active transmission shaft 206 drives the cable reel 207 on the surface to rotate. The cable reel 207 reels the transmission connecting cable 208 during rotation, which drives another cable reel 207 to rotate, so that the driven transmission shaft 205 and the active transmission shaft 206 rotate synchronously, and the rotation and pressing seat on the surface are driven when the driven transmission shaft 205 and the active transmission shaft 206 rotate. When the rotating and pressing seat 504 rotates, the reset spring sheet 505 is pressed down to deform and store force. When the positioning wheel 507 rotates, the positioning between the positioning groove 508 and the positioning block 509 is released. When the eccentric wheel 401 rotates, the lifting block 402 is driven to rise, and slides horizontally along the horizontal groove 405 when the pull block 403 rises. At the same time, the lifting block 402 rises, which pulls the horizontal sliding seat 404 and the lifting block 303 to rise. At this time, the middle slide rail 101 moves along the horizontal groove 405. The sliding seat 106 slides downward to adjust the front and rear position of the seat. After the adjustment is completed, the toggle plate 209 below is released, the reset spring 505 rebounds and pushes the rotating and pressing seat 504 to reset until the rotating and pressing seat 504 is blocked by the gear seat 503. When the rotating and pressing seat 504 is reset, it will drive the driven transmission shaft 205 and the active transmission shaft 206 to rotate and reset respectively, and the transmission connecting cable 208 is driven to be reeled by the rotating cable reel 207. When the driven transmission shaft 205 and the active transmission shaft 206 rotate, It also drives the positioning wheel 507 and the eccentric wheel 401 to rotate, so that the positioning groove 508 is engaged with the positioning block 509. At the same time, the rotation of the eccentric wheel 401 drives the lifting block 402 to descend, so that the lifting block 402 pushes the horizontal sliding seat 404 and the lifting block 303 to reach the lowest point, so that the center and eccentric line of the eccentric wheel 401 are perpendicular to the bottom surface of the lifting block 402, avoiding the lifting block 402 from pushing back. At the same time, the roller groove 305 is engaged and locked with the rotating roller 112, thereby positioning the seat.
