Abstract

An extensible and turnover handle structure for a jack comprises a pivot ear formed at the front end of a base. The pivot ear is provided for a pivot connection with the handle. Moreover, the handle includes an inner pipe inserted in an outer pipe and serves to draw out the inner pipe in use, thus elongating an arm of force relative to the base, and the handle can be turned to a position above a top plate to reduce volume during storage.
