Starting the motor 3, the motor 3 drives the second gear 6 to rotate, the second gear 6 can drive the first transmission rod 7 and the second transmission rod 8 to twist while rotating, and then the first gear 5 is driven to rotate, and the first gear 5 rotates to drive the bevel gear ring 4 to rotate so as to drive the bedplate 1 to rotate. As shown in fig. 6, when the bedplate 1 is at a standstill, the second gear 6 drives the first gear 5 to rotate, and then drives the first gear 5 to rotate slowly, so as to drive the bedplate 1 to rotate slowly. When the bedplate 1 rotates from a static state, the rotating speed of the first gear 5 is gradually increased until the same speed with the second gear 6 is kept, the first transmission rod 7 and the second transmission rod 8 which are twisted in the process are gradually loosened to be kept in a straight line when the first gear 5 and the second gear 6 are at the same speed, and after the same speed, the first transmission rod 7 and the second transmission rod 8 are outwards expanded under the action of centrifugal force when the first transmission rod 7 and the second transmission rod 8 rotate along with the second gear 6, as shown in fig. 8.

If the personnel of standing on platen 1 exceedes motor 3's rated load when too much, motor 3 drives second gear 6 and rotates when starting, first transfer line 7 and second transfer line 8 take place to twist reverse and drive first gear 5 and rotate, the process that takes place to twist reverse at first transfer line 7 and second transfer line 8 can spur first gear 5 and slide to the direction of second gear 6, when the load is too big, the degree of torsion that first transfer line 7 and second transfer line 8 take place is big and then spur first gear 5 and slide to the direction of second gear 6 and break away from the meshing with the inner rack of awl ring gear 4, thereby can't drive platen 1 rotatory.
If the operator fails to operate, or the motor 3 fails to work, so that the first gear 5 and the second gear 6 rotate too fast, the centrifugal force of the connecting roller 13 increases, the connecting roller 13 drives the first gear 5 and the second gear 6 to expand outwards under the action of the centrifugal force, the faster the first gear 5 and the second gear 6 rotate, the larger the outward expansion angle of the first transmission rod 7 and the second transmission rod 8 is, when the connecting roller 13 contacts with the limiting circular truncated cone 31, the maximum rotation speed allowed by the first gear 5 and the second gear 6 is, when the rotation speed of the first gear 5 and the second gear 6 exceeds the maximum rotation speed, the first gear 5 and the second gear 6 further expand, and after the connecting roller 13 contacts with the limiting circular truncated cone 31, the first gear 5 and the second gear 6 are pressed to move downwards, so that the first gear 5 is disengaged from the internal rack of the bevel gear ring 4, and the first gear 5 moves downwards to drive the supporting rod 21 to compress the first compression spring 15, the motor 3 moves downwards to compress the second compression spring 16, so that the bedplate 1 is not driven to rotate any more.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
