Abstract

A m ulti-purpose hand tool assembly is equipped with a spring biased pressing button having a downwardly bent lateral edge which can be in firm registration with a retaining cut of a selective tool bit so as to make the tool bit held in place when external force is applied thereto. The pressing button is pivotally fixed in place by a pivot pin to the hand tool assembly. A plurality of tool bits, such as a screw driver, a knife, a spanner and etc., are pivotally mounted onto a bolt locked in place by a nut at one end of the hand tool assembly. Each tool bit has an end provided with a working head and an opposite end equipped with a mounting hole through which the bolt is led so as to permit the multiple tool bits to be selectively pivoted about the bolt. At the pivot end of each bit is disposed at least the retaining cut which can be registered with the downwardly bent retaining end so as to firmly hold each selective tool bit in an operation position. A chain remover head having two retaining cuts at the pivot end thereof is additionally mounted onto the bolt of the hand tool assembly. Such a structure permits the tool bits to be firmly held in position when force is applied to the hand tool assembly.
