Official abstract text for this publication.
A hand tool includes a handle, a press member, a shank body and multiple latch assemblies. The handle is formed with a receiving cavity and a locating hole in communication with the receiving cavity. The press member is movably disposed in the locating hole. The shank body is fitted in the receiving cavity and movable relative to the handle. The shank body is formed with multiple sockets. The latch assemblies are respectively mounted in the sockets. When the shank body is moved, (for example, slid or rotated) relative to the handle to make one of the sockets aligned with the locating hole, the latch assembly latches the shank body with the handle. When pressing the press member, the latch assembly unlatches the shank body from the handle, the shank body is movable relative to the handle.

What is claimed is: 1. A hand tool comprising: a handle formed with a receiving cavity lengthwise extending along the handle, one end of the receiving cavity being an open end; a circumference of the handle being formed with a locating hole in communication with the receiving cavity; a press member disposed in the locating hole and movable along the locating hole; a shank body, a circumference of the shank body being formed with multiple sockets arranged in a lengthwise direction of the shank body, one end of the shank body being fitted through the open end of the handle into the receiving cavity and movable along the receiving cavity relative to the handle; and multiple latch assemblies respectively disposed in a corresponding socket of the multiple sockets and movable within the multiple sockets, each latch assembly of the multiple latch assemblies having an elastic member for keeping the latch assembly sliding outward from the corresponding socket of the multiple sockets; when a selected socket of the multiple sockets of the shank body is aligned with the locating hole, an aligned latch assembly of the multiple latch assemblies disposed in the selected socket being positioned in a latched position where a top end of the aligned latch assembly is moved into the locating hole to latch the locating hole and connect the shank body with the handle; when pressing the press member, the press member pushing the aligned latch assembly to move out of the locating hole into the selected socket to an unlatched position where the aligned latch assembly is separated from the locating hole to unlatch the shank body from the handle; wherein a wall face of the receiving cavity of the handle is formed with an elongated channel lengthwise extending along the receiving cavity, the shank body having a restriction member received in the elongated channel, the shank body is restricted in the handle when the restriction member abuts against a front wall of the elongated channel; wherein the restriction member and elongated channel are located on one side of the hand tool and the latch assemblies and the press member are located on an opposite side of hand tool from the restriction member and elongated channel. 2. The hand tool as claimed in claim 1 , wherein a top end of a wall face of the locating hole of the handle is formed with a top flange; a protrusion abutment section with a larger outer diameter being formed on the circumference of the press member; whereby when the press member is moved outward from the locating hole, the protrusion abutment section abuts against the top flange. 3. The hand tool as claimed in claim 2 , wherein a bottom end of the wall face of the locating hole is further formed with a bottom flange; the protrusion abutment section being positioned between a top end and a bottom end of the press member. 4. The hand tool as claimed in claim 1 , wherein each latch assembly of the multiple latch assemblies includes the elastic member and an engagement column, the engagement column being disposed in the corresponding socket of the multiple sockets and movable along the corresponding socket; the elastic member being disposed between the engagement column and the corresponding socket to always elastically push the engagement column outward from the corresponding socket; whereby when the corresponding socket is aligned with the locating hole, a top end of the engagement column extends into the locating hole. 5. The hand tool as claimed in claim 4 , wherein an abutment flange is formed on a wall face of each socket of the multiple sockets, the abutment flange serving to abut against the engagement column, whereby the engagement column only partially protracts out of the socket.
