Oscillating structure

The utility model discloses an oscillation structure which comprises a driving mechanism, a positioning mechanism, an oscillation mechanism, a tail end fixing mechanism and a connecting mechanism which are sequentially connected. The oscillation mechanism comprises a main shaft, an oscillation block penetrates through the main shaft, a climbing block sleeves the main shaft, and one end of the climbing block is slidably connected with the positioning mechanism; at least two rolling structures are arranged at the other end of the climbing block; the oscillation block comprises an oscillation seat, the end face, facing the climbing block, of the oscillation seat extends to form at least two inclined blocks, a force release groove is formed between any two adjacent inclined blocks, and the inclined directions of the inclined blocks on the two sides of the force release groove are opposite; the rolling structure is arranged on the end face, facing the climbing block, of the oscillation seat; the number of the roll
