For achieving the above object, the utility model provides following technological scheme: a kind of ripple pearl jackscrew, comprise and be provided with externally threaded jackscrew body, on described jackscrew body, one end is provided with the operating groove for rotating jackscrew body, the described jackscrew body the other end is provided with conflict mechanism, and described conflict mechanism is provided with for the resistance surface inconsistent with bent axle side.
Preferably, the one end away from operating groove on described jackscrew body is provided with mounting groove, and be arranged with conflict ball in described mounting groove groove, described resistance surface is arranged on conflict ball.
Preferably, described resistance surface is the curved surface with certain radian.
Preferably, described jackscrew body sidewall is provided with fastening glue receiving groove.
Preferably, the cross section of described operating groove is regular hexagon.
A kind of piston assembly with ripple pearl jackscrew, comprise piston only and connecting rod, described connecting rod one end is fixedly connected with piston only, the described connecting rod the other end is provided with connecting ring, the connection bearing for being set on bent axle is movably equipped with in described connecting ring, eccentric through-hole is equipped with in described connection bearing, described connection bearing end face outwardly convex forms installing ring, described connecting ring is provided with the tapped through hole of axis and eccentric through-hole axis perpendicular, is provided with ripple pearl jackscrew as claimed in claim 1 in described tapped through hole.
By adopting technique scheme; this piston assembly is arranged on bent axle uses time; just by ripple pearl jackscrew, the inner ring of bent axle and connection bearing can be fixed together; and conflict mechanism is also provided with on this ripple pearl jackscrew; this makes it possible to make ripple pearl jackscrew can realize face when inconsistent with bent axle contact; thus increase the area of contact of conflict bent axle and ripple pearl jackscrew; what bent axle can either be made like this to be connected with connection bearing inner ring is more fastening, but also can play effective protective action to bent axle.

Embodiment
Be described further to the utility model a kind of ripple pearl jackscrew and with the piston assembly embodiment of ripple pearl jackscrew referring to figs. 1 through Fig. 7.
A kind of piston assembly with ripple pearl jackscrew 5, comprise piston only 1 and connecting rod 2, described connecting rod 2 one end is fixedly connected with piston only 1, described connecting rod 2 the other end is provided with connecting ring 21, the connection bearing 3 for being set on bent axle is movably equipped with in described connecting ring 21, eccentric through-hole 31 is equipped with in described connection bearing 3, described connection bearing 3 end face outwardly convex forms installing ring 4, described connecting ring 21 is provided with the tapped through hole 41 of axis and eccentric through-hole 31 axis perpendicular, ripple pearl jackscrew 5 is provided with in described tapped through hole 41, described ripple pearl jackscrew 5 comprises the jackscrew body 51 being provided with outside thread 511, on described jackscrew body 51, one end is provided with the operating groove 512 for rotating jackscrew body 51, described jackscrew body 51 the other end is provided with conflict mechanism, described conflict mechanism is provided with for the resistance surface 53 inconsistent with bent axle side.This piston assembly is arranged on bent axle uses time; just can be fixed together by the inner ring of ripple pearl jackscrew 5 by bent axle and connection bearing 3; and conflict mechanism is also provided with on this ripple pearl jackscrew 5; this makes it possible to make ripple pearl jackscrew 5 can realize face when inconsistent with bent axle contact; thus increase the area of contact of conflict bent axle and ripple pearl jackscrew 5; what bent axle can either be made like this to be connected with connection bearing 3 inner ring is more fastening, but also can play effective protective action to bent axle.
One end away from operating groove 512 on described jackscrew body 51 is provided with mounting groove 513, and be arranged with conflict ball 52 in described mounting groove 513 groove, described resistance surface 53 is arranged on conflict ball 52.After people are selected into ripple pearl jackscrew 5 in installing ring 4, the conflict ball 52 be arranged on like this in ripple pearl jackscrew 5 mounting groove 513 will be inconsistent with the bent axle side running through connection bearing 3, so just there will be two kinds of situations:
1, the resistance surface 53 on conflict ball 52 is direct and bent axle side is inconsistent, and such people just directly can screw ripple pearl jackscrew 5, thus complete the installation steady job of piston assembly and bent axle fast.
2, other outer surfaces outside conflict ball 52 place resistance surface 53 and bent axle side inconsistent, such people just can first turn bent axle, conflict ball 52 inconsistent with bent axle side like this will be driven by bent axle, thus make resistance surface 53 can towards bent axle, so just can continue operation ripple pearl jackscrew 5, allow resistance surface 53 on conflict ball 52 be fitted in completely on the sidewall of bent axle, complete the installment work of bent axle and piston assembly.
And resistance surface 53 is for having the curved surface of certain radian; the radian of its resistance surface 53 can with bent axle to coordinating; such resistance surface 53 is when inconsistent with bent axle; resistance surface 53 just can be made to be fitted in more closely on the sidewall of bent axle; what bent axle was connected with piston assembly is more tight, more firmly, but also can more make resistance surface 53 can equal with bent axle time; maximum resistance surface 53 can be reached amass, can goodly effectively bent axle be protected.
Described jackscrew body 51 sidewall is provided with fastening glue receiving groove 514.By the effect of fastening glue receiving groove 514, people just can in the sidewall filling fastening glue of jackscrew body 51, make ripple pearl jackscrew 5 being selected into after in tapped through hole 41, jackscrew body 51 can be made to stick with tapped through hole 41 is sticky, considerably increase the annexation of ripple pearl jackscrew 5 and installing ring 4.
The cross section of described operating groove 512 is regular hexagon.The operation that can be convenient for people to and use, also can make ripple pearl jackscrew 5 more Marking Guidelines, is convenient for people to carry out mass production to this product, facilitates popularization and the use of product.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technological schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
