The invention discloses a multifunctional socket type wrench which comprises a wrench shell, a telescopic socket, a first hexagonal socket and a second hexagonal socket, wherein a rotating gap is formed in the middle part of a wrench shell; the telescopic socket is connected with a rotating shaft through a connection hole in a rotatable manner; two groups of first rectangular slots and two groups of second rectangular slots are formed in the side wall of an inner cavity of the telescopic socket, and are symmetrically distributed about centers of two end surfaces of the telescopic socket; first limiting blocks are arranged on the side wall of the outer side of the first hexagonal socket; the first limiting blocks are clamped with the second rectangular slots in a sliding manner; a first spring is arranged between the first hexagonal socket and the inner cavity of the telescopic socket; second limiting blocks are arranged on the side wall of the outer side of the second hexagonal socket; the second limiting blocks are clamped with the first rectangular slots in a sliding manner; and a second spring is arranged between the second hexagonal socket and the inner cavity of the telescopic socket. The multifunctional socket type wrench is relatively labor-saving, can ensure that the sockets are not liable to lose and is simple and practical.
