The invention discloses a three-freedom-degree series-parallel type pantograph which comprises a base, a parallel pantograph lifting mechanism, pantograph head shock absorbers and pantograph head sliding plates, wherein support insulators are arranged at four corners below the base; the bottom of the parallel pantograph lifting mechanism is mounted on the base; four groups of the pantograph head shock absorbers are symmetrically fixed on the top of the parallel pantograph lifting mechanism and are used for achieving longitudinal shock absorption of the pantograph; the pantograph head sliding plates are fixed on the tops of the pantograph head shock absorbers through security screws; security grooves are formed in polish rod sections of the security screws and are used for protecting a pantograph body and a contact net. By adopting the three-freedom-degree series-parallel type pantograph, technical defects of a conventional pantograph can be overcome, bearing and shock absorption in three freedom degree directions in a space can be achieved, security accident such as pantograph displacement and net scraping can be also prevented, the working stability, the security and the adaptability to the contact net, of the pantograph can be improved, and the three-freedom-degree series-parallel type pantograph has the advantages of simple structure, convenient mounting, convenient and rapid operation and maintenance, and the like.
