Zusammenfassung:	The invention discloses a gear selecting and shifting mechanism and a speed changing box, and relates to the field of speed changing box structures. The gear selecting and shifting mechanism comprisesa gear shifting assembly, a gear selecting assembly, a gear selecting and shifting piece and a drive assembly. The input end of the gear shifting assembly and the input end of the gear selecting assembly are in transmission connection with the drive assembly, and the output end of the gear shifting assembly and the output end of the gear selecting assembly are connected with the gear selecting and shifting piece. The drive assembly is arranged to selectively drive the gear shifting assembly or the gear selecting assembly to move, and accordingly the gear selecting and shifting piece can be driven to conduct gear selecting or gear shifting work. The gear selecting and shifting mechanism can integrate the gear selecting assembly and the gear shifting assembly, meanwhile, the same drive device is used for driving, a
