Linear actuating device and hair cutting device

Abstract

A hair cutting device includes an installation frame including electromagnet installation and magnet group installation parts, an electromagnet is disposed horizontally in the electromagnet installation part, a magnet group is disposed in the magnet group installation part, and the magnet group is positioned opposite to a magnet pole of the electromagnet. When alternating current is flowed through the electromagnet, a magnetic induction action between the electromagnet and the magnet group causes the magnet group to reciprocate along a direction perpendicular to a central axis of the electromagnet. By arranging the electromagnet horizontally and placing the magnet group on a side of the electromagnet, a horizontal space can be fully utilized, which significantly reduces a height of the linear actuating device and a length of products with the linear actuating device, thereby coordinating a proportion of the product in length and horizontal directions, and enhancing the beauty of the products' appearance.
