Title:
WHEELED WORK TOOL
Document Type and Number:
WIPO Patent Application WO/2022/127935
Kind Code:
A1
Abstract:
A wheeled work tool (100). A buffer mechanism (130) is arranged in a spacing between a floating cover (120) and a main machine (110); and when the main machine (110) is relatively displaced relative to the floating cover (120), the buffer mechanism (130) can act on the floating cover (120) with a buffer force in the opposite direction to the displacement direction of the main machine (110), thereby reducing a collision force applied to an object via the floating cover (120) under the action of a traction force of the main machine (110), and thus ensuring collision safety.
