A telescoping handle assembly includes a first handle, a second handle, a first coupling member, a second coupling member and a driving member. The second handle is movably disposed in the first handle. The first coupling member is movably disposed in the first handle and the second handle. The second coupling member is movably disposed in the second handle. The driving member is coupled to the second coupling member and used for driving the second coupling member to move from a first position to a second position. When the second coupling member is located at the first position, the second coupling member is capable of moving with respect to the first coupling member. When the second coupling member is located at the second position, the first coupling member and the second coupling member are capable of moving together while the driving member is driven.
