At the same time, the power input connection end 8 can be connected to different external power devices, making the operation of the oil pumping equipment more diversified. A spiral head 9 is connected to the bottom of the inner transmission rod 7.

[0030] An oil seal bearing 10 is installed at the bottom of the mounting base 4 and the rotatable connection point of the inner transmission rod 7. A connecting bearing 11 is installed at the top inner side of the mounting base 4 and the rotatable connection point of the inner transmission rod 7. A limit ring 12 is engaged at the contact point between the outer side of the inner transmission rod 7 and the edge of the oil seal bearing 10 and the connecting bearing 11.

[0031] The outer side of the oil outlet pipeline 3 is provided with a connecting external thread 13, and the connecting external thread 13 is connected with the rotating threaded pipe 15 through a threaded connection. The end of the rotating threaded pipe 15 is connected with a limiting sleeve 14. The inner wall of the limiting sleeve 14 is provided as an inclined arc surface.
