Disclosed is a detachable five-star leg, comprising a center block (1) of an outer pentagon, and five supporting legs respectively arranged on side faces of the center block (1), characterized in that: the supporting legs comprise one to four detachable supporting legs (2) and the remaining fixed supporting leg(s) (23), or five detachable supporting legs (2) in total. The detachable five-star leg further comprises clamping plates (3) arranged on two sides of each of the five side faces of the center block (1); arc-shaped groove plates (4) arranged at a lower end position on inner side faces of the clamping plates (3); connection grooves (5) arranged on connection ends of the detachable supporting legs (2); arc-shaped connection plates (6) arranged on the connection grooves (5) and used for being fixed to the arc-shaped groove plates (4) in a hooked manner; supporting blocks (7) arranged on the side faces of the center block (1), located between two clamping plates (3), and used for supporting upper groove plates of the connection grooves (5); and push-up blocks (8) arranged between two arc-shaped connection plates (6) and used for blocking and limiting lower portions of the supporting blocks (7) before same are inserted and for supporting same upwards after same are inserted. The five-star leg detachment structure is rational and effective, has the advantages of detachable supporting legs being easily clamped and positioned before detachment, the resistance being moderate and the operation being convenient during detachment, the supporting strength being great after mounting, a friction fixing effect between the detachable supporting legs and the center block being great and the detachable supporting legs not being easily rotated to drop off and to be disassembled when lifted off the ground, the number of the detachable supporting legs being adjustable, and the overall detachment workload and detachment time being flexible and efficient, and thus different usage requirements can be satisfied.
