SOCKET APPARATUS

Provided is a socket apparatus, which comprises a base body, a movable member, a biasing member, and a jack. The movable member is movably arranged to the base body along a first direction between a use position and a storage position. The biasing member applies an action force toward the storage position to the movable member. The jack is located at one of the base body and the movable member. The movable member located in the use position extends at least partially beyond the base body. Moreover, when the movable member is located in the use position, the maximum size of the socket apparatus along the first direction is a first size; when the movable member is located in the storage position, the maximum size of the socket apparatus along the first direction is a second size; and the first size is larger than the second size. Therefore, the overall volume of the socket apparatus may be reduced so as to facilitate carrying and transportation. L'invention concerne un appareil à douille, qui comprend un corps
