Abstract
The present invention discloses a punch-free telescopic rod, comprising an inner tube and an outer tube sleeved together. A first elastic part is connected to the inner tube. When the two tubes rotate relative to each other, the first elastic part and the insertion end squeeze each other to lock the two tubes; when the two tubes rotate in opposite directions, the first elastic part and the end face of the insertion end are separated from each to unlock the two tubes. The structure of the present invention is very simple and can achieve stable locking.
