Structure that directly links electronic jar of formula

The utility model belongs to directly link the electronic jar mechanical structure of formula design field, relate to (b a) structure that directly links electronic jar of formula (b), this structural change the joint mode of lead screw and bearing housing, on optical axis complex basis, add one section screw thread mode of closing soon to the shaft coupling is the lug connection lead screw no longer, but connects bearing cover and motor shaft, simultaneously the utility model discloses an improve the part structure, make electronic jar with little screw connections. The electronic jar inner structure of the company's of straightening formula of this kind of structure is simpler compact, and manufacturing cost is lower.
