A multiple screwdriver includes a tubular body having, at one end, a tip and, at the other end, a cap. The tubular body has an axially extending bore, a first cylinder end in a zone of the tip and a second cylindrical end in a zone of the cap. Between the end of the first cylindrical end and a rim with a hexagonal opening provided at an exit of the tip, a C-shape springy element is located. The internal circumference of the latter circumscribes the hexagonal opening, so that a shank of an interchangeable screwdriver tip can be prevented from falling out. After several interchangeable screwdriver tips are inserted successively through the top of the cap into the axially extending bore and the first interchangeable screwdriver tip has its bit projecting out of the tip, the last interchangeable screwdriver tip is so situated that its top is beneath a hexagonal configuration provided at the top of the switch. By pivoting the switch to the right or left, the hexagonal configuration can coincide or not with a hexagonal cross section of the axially extending bore. If it coincides, the tips can be inserted or let fall out. When it does not coincide, the interchangeable screwdriver tips are confined in the tubular body.
