Lower end first joint of described first axle, described first joint has the first projection, the end of described first projection arranges the first bulge loop, the upper end of described second axle arranges the second joint, described second joint has the second projection, the end of described second projection arranges the second bulge loop, and described first joint and described second joint are oppositely arranged, to form linkage section;
Described linkage section place arrange by left and right Connection Card circle formed fastening with connecting collar;
Described first axle and the described second sheathed outer coupling band in shaft connection place, and undertaken fastening by Cock screw and first, second connecting key.
Preferably: described first joint and described second joint are symmetrical arranged.
Preferably: described left and right connection collar is arranged symmetrically with, and left connection collar has main part, described main part is arranged the draw-in groove being used for first, second joint fastening.
Preferably: described Cock screw is arranged on the bottom of described outer coupling band, and the second axle arranges tightening recess with Cock screw corresponding part.
Preferably: described Cock screw is two right, is arranged symmetrically in the both sides of outer coupling band.
Preferably: the bottom of described first joint and the top of described second joint, be plane structure.
Compared with prior art, the utility model has following beneficial effect: the utility model ensure that the bond strength of structure; In the utility model, the machining accuracy of each part is easy to ensure, without assembly error, really achieves the connection of axle; The pump shaft of the spindle structure in the utility model is general longer, and the part form and position tolerance of collar-type spindle device is easy to ensure, the amount of deflection assembling rear axle is very little, pump operation is steady, and vibrate little, noise is low, and the easily damaged partss such as sliding bearing not easily wear and tear, improve the working life of easily damaged parts.
