Document Type and Number:
Japanese Patent JP4584149
Kind Code:
B2
Abstract:
A work tool according to the invention is configured in such a manner that when an operator performs a predetermined operation by gripping a gripping section and opening/closing an active section, the opening and closing operation can be achieved smoothly without employing a spring by gripping the gripping section strongly and releasing the same because a repulsive force of magnets urges two pressure-nipping members in the direction in which the gripping section opens. The work tool according to the invention includes an active section 1 for performing cutting, formed on two pressure-nipping members A and B, the pressure-nipping members A and B being overlapped one on top of another and joined pivotably at respective mid-sections thereof so as to be crossed with respect to each other, the active sections 1 formed on distal end sides of a pivotal joint spot 2 of the respective mid-sections, and a gripping section 3 formed by the two pressure-nipping members A and B on proximal end sides of the pivotal joint spot 2 to be opened and closed for opening and closing the active sections 1, and is characterized in that magnets 4a, 4b are provided respectively on the two pressure-nipping members A and B at positions facing to each other in the vicinity of the pivotal joint spot 2 on a side of the gripping section 3 so as to be repulsive when being mounted with the same pole faced to each other.
