Modular Brush

Modular brush characterized by any one of

• construction comprising a ferrule (60) arranged at the end of a handle (10), a bristle-attaching portion (70), which is partially accommodated in the ferrule (60) and has bristles (71) on one side and any one of shaft (72) downwardly extending on central lower surface of the bristle-attaching portion (70) or a plurality of bars (73) attaching to lower surface of the bristle-attaching portion (70), wherein the shaft (72) or the bars (73) are drawn downwardly of the ferrule (60) so that the bristle-attaching portion (70) can flex in a curved manner with respect to its center and the bristle-attaching portion (70) can be accommodated in the ferrule (60) with diameter of the bristle-attaching portion (70) reduced, wherein the bristle-attaching portion (70) can flex in a curved manner with respect to its center portion and the bristle-attaching portion (70) can encase the shaft (72) outside the shaft (72) to further reduce diameter of the bristle-attaching portion (70), wherein tube (74) having larger diameter than that of the shaft (72) is further provided and its end is fixed to a lever fixing portion (61) arranged in inner wall of the ferrule (60), wherein a lever (62) is inserted into guide hole (72a)(74a) formed in the shaft (72) and the tube (74) and configured to penetrate guide hole (60a) formed in the ferrule (60) so that the lever (63) can move downward along the guide hole (60a) of the ferrule (60) and position of the shaft (72) is temporarily maintained wherein the bar (73) and tube (74) primarily moves downward and the lever (62) pushes the shaft (72) with reduced diameter of the bristle-attaching portion (70) so that the bristle-attaching portion (70) is inserted into inner wall of the ferrule (60) without contact;
• or construction comprising track (63) having groove shape configured along perimeter of the ferrule (60), an adjuster-ring (64) provided with pin (64a), which is configured to protrude inwardly wherein the pin (64a) is configured to insert into curved guide holes (72b)(74b) arranged on outer surface of the shaft (72) and tube (74) and the adjuster-ring (64) is adjusted with the pin (64a) inserted into the guide holes (72b)(74b) so that velocity of downward movement of the shaft (72) and tube (74) is respectively adjusted according to curved shape of the guide holes (72b)(74b), wherein the bristle-attaching portion (70) is inserted into the ferrule (60) with reduce diameter;
• or construction comprising the shaft (72) provided with a plurality of bars (73), which are configured to extend outwardly of the shaft (72), wherein the tube (74) provided with guide hole (74c), into which the bar (73) penetrates, so that the shaft (72) can upwardly or downwardly slide with constant distance, wherein the bristle-attaching portion (70) is inserted into the ferrule (60) with retraction according to adjustment of polarity of moving magnetic bodies (39e) configured on one side of the shaft (72) and fixed magnetic bodies (39b) provided on coupling (14) of the handle (10)
• or construction comprising a spring (76) arranged between distance plate (65) provided at the center of the ferrule (60) and a stopper (75) configured by outwardly protruding end of the shaft (72) wherein the bristle-attaching portion (70) is connected with the coupling (14) with retraction so that the bristle-attaching portion (70) can be inserted into the ferrule (60) with retraction due to the spring (76).
