Zusammenfassung:The invention discloses a sucker rod assembly which comprises a rod body and a coupling. The rod body comprises a first connector, a first rod body and a second connector which are sequentially connected. The first connector and the second connector are provided with external threads and are the same in type. The two end faces of each rod body are provided with a protruding part and an inner concave part correspondingly, so that the two adjacent rod bodies can be aligned in the mode that the protruding parts and the inner concave parts are connected in an inserted mode. The coupling is provided with an internal thread matched with the external thread so that the two adjacent rod bodies can be connected through the coupling. Compared with the prior art, when the sucker rod assembly is used, the two adjacent sections of rod bodies can be connected through the couplings, so that the overall length of the sucker rod assembly is adjusted to adapt to oil wells with different depths. 本发明公开了一种抽油杆组件,包括杆体和接箍。杆体包括依次相连的第
