Title:
TOOL DEVICE AND REACTION FORCE RECEIVER
Document Type and Number:
WIPO Patent Application WO/2018/198977
Kind Code:
A1
Abstract:
[Problem] When the rotation torque of a tip tool is increased, it becomes difficult to receive a reaction force that occurs during rotation of the tip tool. [Solution] A tool device (1) has a deceleration unit (30), a tip tool (40), and a reaction force receiver (50). The deceleration unit increases a torque that is input to the deceleration unit. The tip tool is rotated when receiving a motive force from the deceleration unit. The reaction force receiver is fixed to the deceleration unit. An external force can be made to act on the reaction force receiver to receive a reaction force that is generated during rotation of the tip tool.
