The utility model discloses a labor-saving device for a jack, and relates to the field of small repairing machines and tools. The labor-saving device for the jack solves the problem that an existing jack needs great effort to be lifted, and comprises a shell and a transmission mechanism arranged in the shell. The transmission mechanism comprises a pinion and a big gear wheel meshed with the pinion. Positioning bearings are arranged on the two sides of the pinion and fixed to the two sides of the inner wall of the shell. A one-piece gear shaft is arranged on the pinion, the two ends of the gear shaft are fixed to the positioning bearings respectively, and one end of the gear shaft extends out of the shell and is provided with a torsion ring. One end of a lead screw is fixed to a central shaft of the big gear wheel, and the other side of the big gear wheel is provided with a pressure bearing. When the labor-saving device for the jack is used, a handle is connected to the torsion ring, the handle is rotated to drive the pinion to rotate, the rotating pinion drives the big gear wheel to rotate, the rotating big gear wheel drives the lead screw to rotate, and therefore the jack is driven to be lifted. According to the labor-saving device, the big gear wheel is driven by the pinion, the speed is reduced, and the hand cranking frequency is increased, so that hand operation saves labor, and the labor-saving device for the jack has the advantages of being low in cost and easy to operate.

Embodiment
For making that the utility model is done further to understand, below with reference to Figure of description and specific embodiment, the utility model is described in further detail:
As shown in Figure 1 to Figure 3, a kind of labour-saving device of jack, comprise housing 1 and be located at the driving mechanism in described housing 1, wherein, the gearwheel 3 that described driving mechanism comprises small gear 2 and engages with described small gear 2, described small gear 2 is provided with the gear shaft 5 of disjunctor, and axis hole one side of described gearwheel 3 is provided with the screw mandrel fixed block 7 for fixing screw mandrel 4 heads.
In the present embodiment, the both sides of described small gear 2 are provided with positioning bearing 6, and described positioning bearing 6 is fixed on the inwall both sides of described housing 1, and described gear shaft 5 two ends are separately fixed on positioning bearing 6.Wherein one end of this gear shaft 5 is stretched out described housing 1 and is provided with endways torsion circle 51, and this torsion circle 51 is shaken the hand for being socketed annex, and this kind of structure is convenient to dismantle and shaken the hand, easy to carry.Described housing 1 also comprises an end cap 11, this end cap 11 is provided with symmetrical lug 12, fixing bolt 13 on described lug 12, the axis of bolt 13 is vertical with the axis of screw mandrel 4, the middle part of bolt 13 is provided with the perforation vertical with the axis of bolt 13, screw mandrel 4 is through the perforation of bolt 13, and bolt 13 plays the effect of support to screw mandrel 4.Between described end cap 11 and described bolt 13, be provided with pressure bearing 15, between pressure bearing 15 and end cap 11, be also provided with the pad (not shown) playing the role of positioning, pressure bearing 15 can significantly reduce screw mandrel 4 and rotate the frictional force producing, and has reduced the rotation torsion of screw mandrel, more laborsaving in use.The central shaft of described gearwheel 3 is provided with fixing rod 8, the other end of described fixing rod 8 is fixed on the second positioning bearing 61 on described housing 1, by positioning bearing 6, the second positioning bearing 61 and pressure bearing 8, can make small gear 2 and gearwheel 3 reduce friction in the time rotating, and not easy to wear.For preventing that screw mandrel 4 from surpassed distance occurring in use, screw mandrel 4 is provided with sleeve pipe 14 in the one end near described end cap 11, and sleeve pipe 14 is provided with fixture block (not shown), and this sleeve pipe 14 can play spacing effect, can prevent that screw mandrel 4 from surpassed distance occurring in use.
