Title:
ELECTRIC TOOL CAPABLE OF LIMITING TURNING OF WORKING COMPONENT
Document Type and Number:
WIPO Patent Application WO/2024/082409
Kind Code:
A1
Abstract:
An electric tool capable of limiting the turning of a working component, comprises: a holding component (10), a driving component (20), and a working component (30), wherein the electric tool has provided therein a turning control assembly; the working component has provided thereon a mounting guide column (32) docked with the driving component, an end portion of the mounting guide column being designed with a stepped structure (321); when the working component can only perform unidirectional driving operation, the stepped structure has a semi-stepped structure, and a protruding portion (322) thereof abuts against the turning control assembly after the working component and the driving component are assembled, preventing the back-and-forth motion thereof, and limiting the working component to only be able to perform unidirectional operation; and when the working component can perform bidirectional driving operation, the stepped structure is of a fully-stepped structure, allowing the steering control assembly to smoothly slide over the stepped structure. The electric tool is able to limit a working component to unidirectional or bidirectional operation without major changes to the structure of existing electric tools, avoiding safety accidents caused by misuse of the electric tool during operation.
