The embodiment of the invention discloses a push-and-pull device for a drill collar and relates to the technical field of machines. The push-and-pull device can improve operation efficiency and carry out push-and-pull operation more accurately and more stably at the same time. The push-and-pull device comprises a locking component, an outer sleeve, a centering sleeve, an end cap, a nut and a lead screw. The nut rotates and drives the lead screw to move axially. The locking component is arranged at one end of the lead screw and used for locking an object to be pushed and pulled. The lead screw drives the object to be pushed and pulled to move axially. The push-and-pull device for the drill collar is mainly used for push-and-pull disassembly and assembly, and particularly used for the push-and-pull disassembly and assembly of an electronic bin.
