Provided is a holder set with stepless adjustment, which includes a first frame and a second frame capable of sliding relative to each other. The first frame is provided with a control member for being manually operated by a user. The control member is provided with a first part moving along a reciprocating trajectory with respect to the first frame, a second part moving along an advancing and retreating trajectory with respect to the first frame, and an elastic part disposed between the first part and the second part. When the first part is disposed at one end of the reciprocating trajectory, the elastic part is fully extended and the second part does not abut upon the second frame. When the first part is disposed at a specific position of the reciprocating trajectory, the second part abuts upon the second frame and the elastic part is compressed to minimum. When the first part is disposed at the other end of the reciprocating trajectory, the second part still abuts upon the second frame and the elastic part
