A kind of push-button type telescopic rod of the related what of the present invention,In mainly being controlled using the cooperation between a Location resilient piece and a control assembly,Flexible positioning between outer tube,Control assembly therein have a Mobile base,One push button,And one set moving part between what Mobile base and push button,When push button is not by external force,Location resilient piece will receive the ejection of Mobile base and by the location indentations of the positioning convex portion of engaging what inner tube itself,Be displaced outer tube can not with respect to inner tube to complete to position,When push button is pushed by external force,Push button can drive Mobile base mobile towards the direction of remotely located elastic slice through moving part,Make Location resilient piece that the positioning convex portion of itself be forced to be detached from the location indentations of inner tube by the back stretch of itself,Outer tube at this time can be displaced with respect to inner tube and achieve the effect that adjust length.本發明有關於一種推鈕式伸縮桿，主要是利用一定位彈片與一控制組件之間的配合來控制內、外管之間的伸縮定位，其中的控制組件具有一移動座、一推鈕，以及一設於移動座及推鈕之間之連動件，當推鈕未受外力作用時，定位彈片會受到移動座之推頂而藉由本身之定位凸部卡合於內管之定位凹部，使外管無法相對內管位移來完成定位，當推鈕受外力推動時，推鈕會透過連動件帶動移動座朝遠離定位彈片的方向移動，使定位彈片藉由本身之回復彈力而迫使本身之定位凸部脫離內管之定位凹部，此時的外管即可相對內管位移而達到調整長度的效果。
