Title:
A MULTIFUNCTIONAL ELECTRIC TOOL
Document Type and Number:
WIPO Patent Application WO/2008/128418
Kind Code:
A1
Abstract:
A multifunctional electric tool 100 includes: a housing 1, a motor 11 provided
in the housing 1, a spindle 24 which is driven to rotate by the motor 11, and a working
shaft 51 which extends to the outside of the housing 1. An active impacting block
31 is provided on the spindle 24, it rotates with the spindle 24 and moves axially
relative to the spindle 24. A passive impacting block 41 is provided on the working
shaft 51, it rotates with the working shaft 51 and moves axially relative to the
working shaft 51. A first end tooth 311 is provided on the active impacting block
31, and a second end tooth 411 is provided on the passive impacting block 41; the
active impacting block 31 drives the passive impacting block 41 to rotate through
the cooperation of its first end tooth 311 and the second end tooth 411 of the passive
impacting block 41; the electric tool 100 also includes a function changeover
knob 44, and the function changeover knob 44 can selectively restrict the axial
movement of the passive impacting block 41 relative to the working shaft 51 between
a first position and a second position, so as to achieve the switch between a first
function and a second function. The function changeover mechanism is simple
in structure, low cost to manufacture, convenient to operate and can save labor.
