A multi-stage sliding structure of a handheld device includes a first sliding block, a second sliding block, and an engagement structure. The first sliding block has at least one first groove for containing a first magnetic strip. The second sliding block has at least one second groove. The second groove is for containing at least two second magnetic strips which are continually spaced apart in the second groove, and the directions of magnetic poles of the second magnetic strips correspond with directions of respective magnetic poles of the first magnetic strip. The engagement structure includes two structures disposed near outer sides of the first and the second grooves respectively, and is for enabling the first and the second sliding blocks to engage with each other and slide with respect to each other.
