A foldable cane comprises a first rod, a second rod, and a linking unit. The first rod comprises a connecting end with an outer thread. The second rod comprises a joining end with an inner thread and may be detachably screwed with the first rod. The linking unit comprises a first positioning member connected with the connecting end, a second positioning member penetrated through the joining end, and a connecting member connected between the first and second positioning members and being foldable with respect to the first and second positioning members respectively. When the first and second rods are screwed together, the linking unit is hidden within the first and second rods. The present invention utilizes the design of the linking unit to be hidden within the first and second rods, so as to reduce the possibility of damage for the linking unit, improve the overall appearance, and achieve better robustness.一種可折收拐杖,包含一第一桿件、一第二桿件,及一聯結單元。該第一桿件包括一具有一外螺紋的連接端部,該第二桿件包括一具有一內螺紋的結合端部,該第二桿件可分離地螺鎖於該第一桿件。該聯結單元包括一連接於該連接端部的第一定位件、一穿設於該結合端部的第二定位件,及一連接該該第一、第二定位件間且可分別相對該第一、第二定位件彎折的連接件。當該第一、第二桿件螺鎖時,該聯結單元隱藏於該第一、第二桿件內部。本發明藉由該聯結單元可隱藏於第一、第二桿件內部的設計,藉此達成降低該聯結單元耗損的可能情形並提升整體美觀,且穩固性佳。1‧‧‧第一桿件11‧‧‧連接端部111‧‧‧外螺紋12‧‧‧外管體13‧‧‧端塞2‧‧‧第二桿件21‧‧‧結合端部211‧‧‧內螺紋322‧‧‧第二樞接部323‧‧‧安裝螺紋33‧‧‧連接件331‧‧‧第一短側面332‧‧‧第二短側面333‧‧‧長側面334‧‧‧第一展開孔335‧‧‧第一收折孔212‧‧‧輔助內螺紋213‧‧‧開口214‧‧‧止擋面22‧‧‧外管體23‧‧‧內管體3‧‧‧聯結單元31‧‧‧第一定位件311‧‧‧第一樞接部32‧‧‧第二定位件321‧‧‧抵靠面336‧‧‧第二展開孔337‧‧‧第二收折孔34‧‧‧第一卡掣件組341‧‧‧第一卡掣件342‧‧‧彈簧35‧‧‧第二卡掣件組351‧‧‧第二卡掣件352‧‧‧彈簧91‧‧‧可折收拐杖
