The invention discloses an adjustable pipe column of a slotting and clamping structure. The adjustable pipe column comprises an upper column pipe assembly and a lower column pipe assembly, wherein a lower column pipe protrudes into an upper column pipe, and the upper column pipe assembly is arranged on an adjusting support assembly; the adjusting support assembly comprises an adjusting support, a middle support is arranged inside the adjusting support, the middle support is composed of two branch supports which are respectively fixed with the upper column pipe, and a lower column pipe locking structure is arranged between the upper column pipe and the lower column pipe; when the adjusting handle is located in a locking position, the side of the adjusting support and the side of the middle support are locked in a friction way; meanwhile, the upper column pipe acts on the lower column pipe to lock the lower column pipe through the lower column pipe locking structure. The lower column pipe locking structure acts on the lower column pipe to lock the lower column pipe by the lower column pipe locking structure, therefore the loosing of a steering pipe column can be prevented in a locking state, and the reliable locking of the steering pipe column can be ensured.
