Spiral connects；Tappet 9. is inserted in 1. sleeves, rocking-turn handles 5 counterclockwise make the precession tappets of screw rod 12 of worm gears, make tappet
Retraction, treat it is spacing cross the segment distances of closing piece support 7-1 mono-, then by closing pieces 7-2 through after square hole insertion guide groove 8, with closing piece spiral shell
Bolt is fixed on closing piece support 7-1, then examines the flexibility of present apparatus action, and rocking-turn handle 5 clockwise makes tappet stretch completely
Go out, another mistake hour hands rocking-turn handle 5 is fully retracted tappet, confirms flexibly to complete without clamping stagnation, assembly working.
Its operating method is：When needing to jack up weight, the top of tappet, rocking-turn hand clockwise will be placed on by a heavy articles
Handle 5, in the presence of worm gear drive mechanism, tappet is stretched out upwards, and required height arrive until weight is jacked up, stopping rocking-turn " 5.
Handle ", weight is set to be maintained at this height；When needing to decline by a heavy articles, rocking-turn handle 5. counterclockwise makes tappet complete
Retract, played heavy articles and drop to required height, stopped rocking-turn handle 5, serve the effect of jack.
If necessary to which two weight distances are furthered, bottom traction hook 18 and overhead extension hook 11 are separately mounted to screw
II and screw I 10 on, rocking-turn handle 5 clockwise, tappet 9. is stretched out required length, then a heavy articles will be played and hung over,
Two are hung on bottom traction hook 18 and overhead extension hook 11 by heavy articles are played, then rocking-turn handle 5 counterclockwise, makes tappet contract
Return and two are furthered by heavy articles are played, until moving required distance to, stop rocking-turn handle 5, complete two and played heavy articles
Relative position moves.
If necessary to object be lifted or the segment distance of tethered sliding one is, it is necessary to there is a fixed fulcrum, then up time
Pin rocking-turn handle, tappet reach required length, and any one in the draw hook of ground jack both ends is hung on fulcrum, another
Individual traction, which is hooked on, to be needed on mobile object, and rocking-turn handle clockwise, tappet is retracted, and by object movement or can thus be hung
Get up.
