The invention discloses a telescopic efficient wall-breaking food processer. The telescopic efficient wall-breaking food processer comprises a processer body and a top cover, the top cover is installed at the top of the processer body, and an inner cavity is formed in the processer body; the lower side of the inner cavity is provided with a bottom power cavity, a bottom motor assembly is installed in the bottom power cavity, the output end of the bottom motor assembly is connected with a bottom rotating shaft, the bottom rotating shaft extends upwards out of the bottom power cavity and stretches into the inner cavity, and the tail end of the bottom rotating shaft is provided with a bottom knife; the bottom of the processer body is provided with a plurality of supporting legs; one side of the processer body is provided with a side handle, and the side handle comprises a top side edge, a vertical edge and a bottom side edge. Due to the shake-proof design of the supporting legs, noise generated by shake in the use process can be effectively reduced, and the use experience of a user is improved; besides, due to the upper and lower double-knife design and the telescopic design of an upper knife, the wall breaking effect can be well improved, and the wall breaking efficiency of the wall-breaking food processer is greatly improved.
