Swivel becket 7 moves, and swivel becket 7 will will drive third support plate 9 and move, third support plate 9 will will drive the 4th fixing axle 26 with
The movement of first fixing axle 10, the 4th fixing axle 26 moved at this time will will drive the 4th gear 25 and move, and fluted disc 20 will drive
The movement of 4th gear 25, the 4th gear 25 will drive first gear 8 to move；First gear 8 will be in double rolling key clutch
Under the action of 27, the movement of the first fixing axle 10 not will drive；First fixing axle 10 will not move, it will so that first bevel gear
11, second bevel gear 13, second gear 15, half-ring gear 12 will not move；So that compression bar 14 will not move；Compression bar at this time
14 rotations finish, and compression bar 14 at this time moves up and down, it will drives second gear 15 to move, second gear 15 will be by unidirectional
Ring 29 drives 30 one-way movement of the 5th fixing axle, and the 5th fixing axle 30 will will drive second bevel gear 13 and move, second bevel gear
13, which will will drive first bevel gear 11, moves, and first bevel gear 11 will will drive the first fixing axle 10 and move, the first fixing axle 10
First gear 8 will be driven to move by double rolling key clutch 27, first gear 8 will will drive the 4th gear 25 and move, the
Four gears 25 will will drive fluted disc 20 and move, and fluted disc 20 will drive third gear 24 to move, and third gear 24 will be by soft
Axis drives screw rod 1 to move, and screw rod 1 will will drive two 2 relative motions of movable block, two groups of first support bars 4 at this time and two groups
22 relative motion of third support rod, so that upper support seat 23 moves upwards, to achieve the purpose that top load moves.
