A reciprocating impact slack-drop/rotating/raking multifunctional power shaft, comprising a power shaft section (5), eccentric shaft sections (6), a power take-off (2) comprising a lubricated power take-off (7) and/or a raking power take-off (8), and a power source component (4); the sections (6) comprising bearing separate snap-fitted eccentric shaft sections (6) or bearing integrated sleeved eccentric shaft sections (3); the sections (6) comprising connecting rods (1) comprising separate snap-fitted connecting rods and/or integrated sleeved connecting rods; the power take-off (2) being arranged between the sections (5) and (6), or between the section (6) and the section (6), or at one end of the section (6), or at one end of the section (5); the component (4) driving the section (5) to rotate; the section (6) driving the rod (1) in reciprocating motion; and the section (5) driving the power take-off (2) to operate in rotation.

A reciprocating impact slack-drop/rotating/raking multifunctional power shaft, comprising a power shaft section (5), eccentric shaft sections (6), a power take-off (2) comprising a lubricated power take-off (7) and/or a raking power take-off (8), and a power source component (4); the sections (6) comprising bearing separate snap-fitted eccentric shaft sections (6) or bearing integrated sleeved eccentric shaft sections (3); the sections (6) comprising connecting rods (1) comprising separate snap-fitted connecting rods and/or integrated sleeved connecting rods; the power take-off (2) being arranged between the sections (5) and (6), or between the section (6) and the section (6), or at one end of the section (6), or at one end of the section (5); the component (4) driving the section (5) to rotate; the section (6) driving the rod (1) in reciprocating motion; and the section (5) driving the power take-off (2) to operate in rotation.

A reciprocating impact part non-concentric protruding shaft fixed bearing method, comprising: arranging an eccentric shaft section (12) and a power shaft section (11), arranging eccentric shaft section (12) bearings (8) on the section (12), arranging power shaft section bearings (5) on the section (11); arranging power shaft section bearing retaining rings (10) and eccentric shaft section bearing retaining rings (9) to block the bearings (5) and (8), respectively; arranging connecting rods (2) as separate snap-fitted crankshaft connecting rods or integrated sleeved crankshaft connecting rods, fitting the latter onto the bearing (8); arranging a base (1), arranging the bearings (5) thereon, such that they support the sections (11) and (12); arranging a power source component (3), such that it drives the section (11) to rotate and the section (11) drives the rods in reciprocating impact. Also provided is a non-concentric protruding shaft fixed bearing reciprocating impact part for implementing the method.
