Screw rod will drive rack movement, rack will drive pushing block to move, and pushing block will drive the first supporting block to move, the
One supporting block will drive the movement of the second supporting block by the first spring, when the second supporting block encounters the protrusion barrier on ground
It is that the first spring at this time will deform, so that two the second supporting blocks can be all in painstaking state, to reach
To the purpose to jack Auxiliary support；The effect that inclined-plane and the first supporting block end face are engaged is easy for pushing block and pushes the
One supporting block moves.
In use, supporting mechanism is mounted in the load for needing to support；Driving mechanism is mounted on support machine
On structure；When the space that jack is installed is smaller, and compression bar can not proper motion when rotation angle being needed to be moved；It revolves at this time
Turn compression bar, the compression bar of movement will drive telescopic rod to move, and telescopic rod will drive swivel becket to move, and swivel becket will drive
Three support plates move, and third support plate will drive the 4th fixing axle to be moved with the first fixing axle, and the 4th moved at this time fixes
Axis will drive the 4th gear movement, drive ring that the 4th gear movement, the 4th gear will be driven first gear will to be driven to transport
It is dynamic；First gear will will not drive the first fixing axle to move under the action of double rolling key clutch；First fixing axle will not
Movement, it will so that first bevel gear, second bevel gear, second gear, half-ring gear will not move；So that compression bar will not be transported
It is dynamic；Compression bar rotation at this time finishes, and compression bar at this time moves up and down, it will drives second gear movement, second gear that will lead to
It crosses unidirectional annulus and moves the 5th fixing axle one-way movement, the 5th fixing axle will drive second bevel gear to move, and second bevel gear will
First bevel gear can be driven to move, first bevel gear will drive the first fixing axle to move, and the first fixing axle will be by two-way
Freewheel clutch drives first gear movement, first gear that will drive the 4th gear movement, the 4th gear that will drive driving
Ring moves, and drive ring will drive third gear movement, and third gear will will band by driven by quill shaft screw motion, screw rod
Two movable block relative motions are moved, two groups of first support bars at this time and two groups of third supporting rod relative motions, so that on
Support base moves upwards, to achieve the purpose that top load moves.
