if the center of gravity of the transmission shaft 11 is not at the center of the whole device, at this time, the transmission shaft 11 rotates and tilts around the middle roller 209, so that one end of the transmission shaft 11 tilts downward, thereby pushing the second moving plate 207 at the side to move downward, meanwhile, the first spring 603 is compressed, so that the roller 209 and the U-shaped frame 212 rotate along with the first rotating shaft 211, and when the second moving plate 207 moves downward, the third moving rod 1201 drives the second connecting sleeve 1202 and the fourth moving rod 1203 to synchronously move downward, so that the inclined surface 1205 abuts against the moving ring 1004, thereby pushing the moving ring 1004 and the connecting key 1003 to move, inserting the connecting key 1003 into the first external spline 1001, meanwhile, the fourth spring 1006 is compressed, at this time, the fifth rotating shaft 906 is connected with the power of the fourth rotating shaft 904, the rotation of the first rotating rod 804 drives the driven gear 910 to rotate, and then drives the driven gear 910 to rotate along with the fifth rotating shaft 906, and the fifth rotating shaft 906 drives the fourth rotating shaft 904 and the worm 905 to rotate through the connecting key 1003, and drives the worm gear 908 to rotate, and the third rotating shaft 902 drives the other side to rotate along with the third rotating shaft 213 and the universal shaft 213 to drive the second rotating shaft 213 to rotate through the third rotating shaft 213;

therefore, the gravity center position of the transmission shaft 11 is automatically moved and adjusted, the gravity center of the transmission shaft 11 is ensured to be positioned at the center position of the whole device, meanwhile, the transmission shaft 11 is in a horizontal balance state, at the moment, the U-shaped frame 212 can rotate to a vertical position, finally, the third motor 803 is stopped, at the moment, the inserted link 708 is inserted into the insertion hole 707 again to limit under the action of the second spring 703, so that the clamping of the transmission shaft 11 of the roller 209 is more stable and reliable, when the transmission shaft 11 is assembled, the gravity center position of the transmission shaft 11 can be automatically moved and adjusted when the transmission shaft 11 is clamped, the gravity center position of the transmission shaft 11 is ensured to be positioned at the center position of the whole device, the clamping support of the transmission shaft 11 is more stable and reliable, the damage to the whole booster device can be reduced, and the use effect and service life of the transmission shaft 11 are ensured;

after the clamping is completed, after the automobile body 1 is lifted, the whole device is moved to the bottom of the automobile body 1, and the transmission shaft 11 can be assembled.
