Embodiment Construction

[0011] Referring to the accompanying drawings, a hand tool 1 of the present invention, here an electric hammer (but actually only as an example), is suitable for rotationally driving a drill bit (or workpiece) 2, and the electric hammer includes a The electric motor 3 of the drill bit (or workpiece) 2, the electric hammer also includes a control module 4, the control module 4 is used for, when the drill bit (or workpiece) 2 encounters such as a metal part during the drilling process and the drill bit is suddenly stuck to prevent the hand tool from rotating.

[0012] It should be noted that an electric motor 3 is provided in the hand tool for rotating the driven drill bit (or workpiece) 2 . While the drill bit (or workpiece) 2 is jammed, the hand tool as a whole may still be rotating.

[0013] The control module 4 comprises a block 5 for decelerating the engine 3 and means for detecting the rotary drive of the hand tool 1 , said detection means controlling said deceleration me...

Abstract

The invention discloses a rotary hand tool with an anti-rotation control module. The hand tool (1) with an electric engine (3) for rotationally driving a member (2) to be driven, characterized in that it comprises means (5) for 15 slowing down the engine (3) and means (6) for detecting the rotational driving of the tool (1) so as to control the slowing down means (5) of the engine. This invention applies well to drills, electrically-driven screwdrivers, millstones or electric hammers.

Description

technical field [0001] The invention relates to a hand tool with an electric motor for rotationally driving an anchoring member, a drilling member or a fastening member. The present invention mainly relates to (Reference) drills, electrically driven screwdrivers, grinding discs or rotary hammers. Background technique [0002] When using such hand tools, there may be a risk of sudden blocking of parts being driven by rotation, for example, when the drill bit of a drilling machine strikes a metal part (metal part). live. Consequently, such rotationally driven tools can injure the operator's hand or arm. [0003] From U.S. Patent No. 2004 / 0104034, it is known that a hand tool includes a safety clutch located between the engine and a driven part, the safety clutch is controlled by a torque active control safety module (torque active control) safety module), the torque active control safety module includes a detector that is sensitive to angular shift (being sensitive to), and...
