The third rod 40 can be extended and retracted relative to the second rod 20, and the second rod 20 can be extended and retracted relative to the first rod 10, so that the extension length of the extension rod can be increased. By analogy, the telescopic rod can also comprise four or more rod bodies, and starting from the second rod body 20, the rod bodies positioned in the inner part can be sleeved with a second cushion cover 50 which is the same as the first cushion cover 30. Therefore, the telescopic rod can adapt to more application scenes, and the sliding friction force between two adjacent rod bodies is smaller.

The first cushion cover 30 and the second rod 20 can be fixed to each other only by fixing and matching, and can also be fixed by other methods. Exemplarily, as shown in fig. 2 and 5, the second rod 20 has been provided with a fixing hole 22, the inner peripheral wall of the first pad cover 30 has a protruding fixing protrusion 31, the fixing protrusion 31 is matched with the fixing hole 22, so that the stability of the matching between the first pad cover 30 and the second rod 20 can be improved.
