Manually operated machine tool with a forced rotation eccentric drive

摘要

The tool (10) has a tool holder performing forced rotation of a drive axis (36) changing rotary angle position to a machine housing (11) of the tool by a forced rotation guide (64) in a forced rotation-eccentric mode. A switch is formed for switching an eccentric gear (27) in a single-eccentric mode. A tool shaft is in contact with a rotary angle-guide (67) for guiding the tool shaft. The tool holder maintains a rotary angular position relative to the machine housing within a rotation angle selector limited by the rotary angle-guide.
