What the invention claimed is: 1. An oil artificial lift pumping unit comprising: a motor, said motor comprising a casing, a stator, and a mover, said mover having an inner tube, which has one end connected to an oil delivery pipe and an opposite end connected to a first connector, which has a first oil hole, said stator having a power cable connected to a power supply for causing said mover and the first connector to move alternately up and down; and a pump, said pump comprising a barrel, an oil suction pipe mounted in said barrel, said oil suction pipe having a top end having a second threaded connector, which has a second oil hole, and a bottom end connected to an inner sleeve, which has installed therein a mixing valve, an axially movable valve and a piston, an outer sleeve having a bottom end provided with a bottom one-way oil intake valve, said oil suction pipe matching with an inner socket to hold a one-way mixing flow intake valve, said inner socket and said oil suction pipe defining an oil passage, which is disposed in communication with a piston upper chamber that is defined in between said outer sleeve and said inner sleeve, said piston upper chamber having a third oil hole disposed in communication with said mixing valve; wherein when said mover of said motor is operated to reciprocate said oil suction pipe, crude oil is alternately pumped through said one-way bottom oil intake valve and said one-way mixing flow intake valve to alternately pass through said axially movable valve and said mixing valve to the ground surface. 2. The oil artificial lift pumping unit as claimed in claim 1, wherein said motor further comprises a locating tube, a bush fastened to said locating tube, bearings and oil seals fastened to said bush to support said mover, and rare earth permanent magnets mounted around said inner tube of said mover; said stator is formed of a set of silicon steel plates and a winding and is mounted around said bush. 3. The oil artificial lift pumping unit as claimed in claim 1, wherein said barrel is formed of a motor connector, a socket connector, a plurality of inner sockets, a plurality of outer sockets, and said outer sleeve. 4. The oil artificial lift pumping unit as claimed in claim 1, wherein said motor is a three-phase linear synchronous motor, and said pump is provided at a bottom side of said three-phase linear synchronous motor.
