Hair cutting device
First Claim
1. A hair cutting device comprising:
- a head portion,an outer blade formed with a plurality of blade holes,an inner blade that slidably contacts an inner surface of the outer blade, anda motor which drives the inner blade,wherein the head portion is connected to an upper portion of a main body grip portion having a controller such that the head portion can laterally tilt and vertically move, the head portion is resiliently biased upward,wherein an upper end of the main body grip portion is formed with an opened space into which a lower portion of the head portion is inserted,wherein both front and back surfaces of the head portion have a pair of left and right shaft-bushing portions provided by an annular member, which are connected to an inner surface of the opened space of the main body grip portion such that the left and right shaft-bushing portions can laterally rotate relative to the main body grip portion, vertically move relative to the main body grip portion, and slidably contact the inner surface of the opened space,wherein a contact portion which is provided lower than the pair of left and right shaft-bushing portions and slidably contacts the inner surface of the opened space,wherein the annular member is mounted on an outer surface of the lower portion of the head portion,wherein the pair of left and right shaft-bushing portions respectively provided on both front and back surfaces of the annular member are supported by a bearing formed on the inner surface of the opened space of the main body grip portion such that the left and right shaft-bushing portions can laterally rotate and vertically move, andwherein spring receivers are respectively provided on left and right ends of the annular member to receive push-up springs which resiliently bias the head portion upward.

Abstract
In a hair cutting device, a head portion is connected such that the head portion can laterally tilt and vertically move. The head portion is stably supported in a front-rear direction, connected to an upper portion of a main body grip portion, and resiliently biased upward. An upper end of the main body grip portion is formed with an opened space into which a lower portion of the head portion is inserted. Front and back surfaces of the head portion have a pair of left and right shaft portions which are connected to an inner surface of the opened space such that the shaft portions can turn and vertically move and come into slide contact with the inner surface of the opened space. A contact portion which is provided lower than the pair of shaft portions comes into slide contact with the inner surface of the opened space.
