The present invention relates to a collapsible self-protection bar having a weight which includes a hand-grip bar and a middle bar and a tip bar which are collapsibly formed from the hand-grip bar in such a way that the middle bar and the tip bar are folded so as to minimize the length of the self-protection bar so that it is easy to be carried, wherein the hand-grip bar and the middle bar are respectively made of a lightweight material and the tip bar has a weight of a heavy weight material such that the middle bar and the tip bar are spread in order from the hand-grip bar when a user swings the self-protection bar forwardly holding the hand-grip bar with the hand. Therefore, the collapsible self-protection bar makes the user hardly feel a sense of weight, makes the middle bar and the tip bar be rapidly drawn out from the hand-grip bar by the weight of the tip bar, can apply a proper blow to an object by the weight of the tip bar at the time of crushing protests or protective suppression to thereby enable the user to take proper measures and rapid treatment, and makes the tip bar having the weight accurately carry out a spreading action to push out the middle bar from the hand-grip bar so that the self-protection bar can be folded and spread according to the user′s intention. The collapsible self-protection bar (100) having the weight includes a hand-grip bar (10) and a middle bar (20) on each of which a collapsible knuckle (50) is mounted and each of which has a weight lighter than a tip bar (30), and the tip bar (30) has a weight heavier than the hand-grip bar (10) and the middle bar (20) on each of which the collapsible knuckle (50) is mounted. |
