The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, 2, a kind of collapsible rod cane, comprise the first bar section 1, the second bar section 2 and stay cord 3, the first bar section 1 is provided with branch sleeve 4, branch sleeve 4 is placed in the endoporus of the first bar section 1 by dimensional fits, offer two spin slot structures 41 that are centrosymmetric on its open end, present substantially L shaped shape; The second bar section 2 is provided with the jointing 5 that docks with branch sleeve 4, the back segment of jointing 5 is placed in the endoporus of the second bar section 2 by dimensional fits, its leading portion is the undergauge inserting paragraph that is connected with branch sleeve 4, be provided with two screens points 51 that cooperate with spin slot structure 41 in the outside of undergauge inserting paragraph, during connection, screens point 51 by jointing 5 inserts in the spin slot structure 41 of branch sleeves 4, and rotation positions the first bar section 1 and the second bar section 2 are connected and fixed; Branch sleeve 4 adopts plastic shapings with jointing 5, and stay cord 3 is elastic drag rope, and an end of stay cord 3 is connected on the location-plate 11 of endoporus rear end of the first bar section 1, and the rear end step of the undergauge inserting paragraph of the other end and jointing 5 is connected to a fixed; The screens point 51 of jointing 5 can be located at the front portion of undergauge inserting paragraph, shown in Fig. 5 a, also can be located at the rear portion of undergauge inserting paragraph, shown in Fig. 5 b, like this, the spin slot structure 41 of corresponding branch sleeve 4 also is located on the open end of close front end or rear end.
