Telescopic ladder
A telescopic ladder comprises two supporting components and a ladder frame supported by the supporting components, wherein the ladder frame comprises two parallel sleeve rods, two telescopic rods detachably accommodated into the corresponding sleeve rods respectively, and a plurality of transverse rods detachably arranged between the two sleeve rods and the two telescopic rods at intervals, wherein each telescopic rod is adjustably accommodated into the corresponding sleeve rod to enable the ladder frame to adopt a telescopic structure; each supporting component comprises a cylinder body and a supporting piece telescopically connected onto the cylinder body; each cylinder body is detachably connected to the corresponding sleeve rod; each supporting piece can stretch out of or retract into the interior of the corresponding cylinder body under the driving action of the corresponding cylinder body, or part of each supporting piece stretches out of the corresponding cylinder body, so as to adjust the supporting height of the ladder frame. The telescopic ladder is small in occupied space and high in use safety during operation.
