A tool with an interference-fit structure includes a main body, an adjustment member, and an interference-fit member. One end of the main body is defined as a connecting end. The adjustment member is connected to the connecting end, with an adjustable distance formed between the connecting end and the adjustment member. The adjustment member can be moved with respect to the connecting end to adjust the adjustable distance. The interference-fit member is provided between the adjustment member and the connecting end, and the outer diameter of the interference-fit member can be changed by changing the adjustable distance. By adjusting the adjustable distance between the adjustment member and the main body, the outer diameter of the interference-fit member can be changed to achieve an effective interference fit between the interference-fit member and the inner wall of a tube, thereby securing the tool in the tube.
