the locating part with headspace has between the main part, when stirring piece with the pivot is pegged graft to cooperate, the locating part orientation is kept away from headspace direction produces the deformation, so that the locating part can be followed the pivot slides extremely the spacing inslot.

In the above scheme, the headspace has between locating part and the main part for hold the pivot, when stirring and pivot grafting cooperation, the axial downstream of pivot can be followed to the stirring, and at this in-process, the locating part slides along the outer wall of pivot, and the outer wall of pivot can prop up the locating part, makes it produce the deformation along the direction of keeping away from the headspace, in order to ensure that the locating part can get into the spacing inslot smoothly. Specifically, when the limiting part slides to a position corresponding to the limiting groove, the acting force exerted on the limiting part by the outer wall of the rotating shaft is reduced or cancelled, the deformation of the limiting part is recovered, and the limiting part can smoothly enter the limiting groove. At the moment, the stirring piece is assembled in place with the rotating shaft, the limiting piece is matched with the limiting groove, the connection stability of the stirring piece and the rotating shaft can be improved, and the effect of preventing the stirring piece from falling off from the rotating shaft is achieved.

In a possible design, both ends of the limiting member along the length direction are riveted to the same side of the main body so as to form the reserved space with the main body.

In the above scheme, adopt riveted mode can ensure the joint strength between locating part and the main part, prevent that the locating part from droing from the main part, can also reduce the technology degree of difficulty of stirring. The locating part is all riveted in same one side of main part along length direction's both ends for the locating part is whole to be the arc structure, compares in the loop configuration, and certain cost can be saved on the one hand to the locating part of arc structure, and on the other hand also is convenient for stir the installation and the dismantlement of piece.

In one possible design, the stopper is a rod-shaped structure with elasticity.

In the above scheme, when the locating part is rod-shaped structure, its volume can not be too big, can slide to the spacing inslot smoothly, is favorable to realizing the rapid Assembly of stirring piece and pivot, can reduce the clean dead angle of stirring piece simultaneously, is convenient for clean. And, the locating part has elasticity, and at the in-process with the pivot complex, the locating part can produce elastic deformation to ensure to slide in the spacing groove smoothly, simultaneously, also can resume deformation fast, in order to ensure with spacing groove interference fit, reach the purpose of effective anticreep.

In a possible design, the side wall of the rotating shaft has a guide surface, the guide surface includes an arc segment, and the limiting member is in sliding fit with the arc segment, so that the limiting member deforms toward a direction away from the reserved space.

Among the above-mentioned scheme, when stirring piece and pivot when assembling, the locating part is along the axial downstream of pivot, and can take place sliding fit with the cambered surface section at the motion in-process, and at sliding fit's in-process, the cambered surface section can play the guide effect to the motion of locating part, can make its orientation produce the deformation towards the direction of keeping away from the headspace simultaneously to ensure that the locating part can get into the spacing inslot smoothly.
