The beneficial effects of the utility model are: adopt said structure, because the operating mechanism rotating for drive shaft in the utility model consists of manual rocking handle, motor, the first transmission gear and the second transmission gear, therefore people both can open motor, engagement by the first transmission gear and the second transmission gear links to drive rotating shaft to rotate, rotating shaft rotate after can by big gear wheel and miniature gears coordinate drive screw mandrel to rotate, after screw mandrel rotates, Timing Belt movable wire bar is overlapped to oscilaltion, thereby make jack-up to be held in the palm thing or decline; Simultaneously people also can be first drive axis of elasticity that the second transmission gear overcomes Compress Spring to outside movement by rotating clutch eccentric wheel, thereby make the second transmission gear separated with the first transmission gear, now people can insert manual rocking handle and come manual drives rotating shaft to rotate, thereby realize the flexible switching between manual, electronic, be convenient to people and operate better use jack.Separately, due to described, take over a business to be provided with spherical surface hill, the corresponding spherical groove embedding for described spherical surface hill that is provided with on described screw rod bushing, and between described spherical surface hill and spherical groove, pass through bolt axial restraint, therefore described in, take over a business when jack-up is held in the palm thing, if local pressure is uneven, can coordinates and rotate force balance by the sphere of described spherical surface hill and spherical groove; In addition, take over a business upper surface and be provided with antiskid groove and can also effectively prevent from being ask thing to slide on taking over a business, therefore by above-mentioned setting, can make jack provided by the utility model carry better and be held in the palm thing.
The axial outer end end face that the utility model can further be set to described rotating shaft is provided with connection recess, and on described manual rocking handle, corresponding being provided with can form the grafting piece of pegging graft and coordinating with the described recess that is connected.
Adopt above-mentioned setting, by described connection recess and the effect of grafting piece can make to form simply between manual rocking handle and rotating shaft and easily detachable installation coordinate.
The utility model also can further be set to described antiskid groove and be corrugated setting.
Adopt above-mentioned setting, can make described antiskid groove can play anti-skidding effect better.
