The utility model relates to the technical field of reversing and gear shifting devices, in particular to a lever type coaxial reversing and gear shifting device with large gear shifting force. The speed changing box comprises a speed changing box and a reversing gear shifting mechanism arranged on the outer side of the speed changing box in a lever mode, the reversing gear shifting mechanism comprises a gear shifting rod, and the middle of the left side of the gear shifting rod is hinged to a hinge seat of a speed changing box shell. The left end of the gear shifting rod is hinged to a gear shifting fork shaft of the gearbox, and the gear shifting fork shaft is fixed to a shell of the gearbox through an oil seal seat. The right end of the gear shifting rod is connected with the stay wire support through a stay wire. The gear shifting device is compact in structure, the gear shifting rod is connected with the oil seal base, the hinge base and the stay wire support, the problem that the gear shifting force of an agricultural machine gearbox is large is solved, and the gear shifting force is effectively reduced; the gear shifting rod and the stay wire support are reasonably arranged, the stay wire is always in a linear state, and bending of the stay wire caused by the space problem of the whole vehicle can be avoided.
