The invention discloses a telescopic structure. The telescopic structure comprises a frame body with a strip-shaped groove, a telescopic body, an elastic body, a sliding part and a control part. The telescopic body is provided with an annular groove and is arranged in the frame body, the elastic body is connected with the frame body and the telescopic body, the sliding part is limited between the strip-shaped groove and the annular groove, and the control part is arranged on the telescopic body. The annular groove corresponds to the strip-shaped groove, and the annular groove is defined by an outer side wall, a bottom face and an inner side wall; the outer side wall is provided with a first limiting portion, a first guide portion, a second guide portion and a third guide portion; the inner side wall is provided with a fourth guide portion, a fifth guide portion, a second limiting portion and a sixth guide portion; and the fourth guide portion, the fifth guide portion, the second limiting portion and the sixth guide portion are staggered from the first limiting portion, the first guide portion, the second guide portion and the third guide portion respectively. Therefore, the telescopic body can stretch out and draw back relative to the frame body.
