回動しない予防手段が設けてある。(Function) The function and effect of this invention will be explained with reference to FIGS. 5 and 6. As shown in FIG. 5, the tip of the rotating shaft 7, which is mounted on a support means provided on the head of the holder 3, is directly attached to the center of the back of the cartridge C, or a freely attachable support base 7 is attached. The cartridge C attached thereto may be of a sliding type generally available on the market, or may be of a vertically moving type found in general two-blade holders. In this case, it becomes a complex movement of up, down, left and right. When shaving the holder 3 by pressing it against the shaving surface at a horizontal position perpendicular to the longitudinal center line of the holder 3, the blade tip that is inserted into the cartridge C and takes a horizontal position hits the shaving hair and the cartridge is removed due to the shaving load. By generating a moment with respect to the center line of C, the cartridge C is rotated, and while applying the pull-cutting principle, the angle of the blade edge is apparently reduced, the sharpness is improved, and shaving can be performed with less fatigue of the blade edge. The rotation of the cartridge C is controlled by an external cam 11 provided at the head of the rotation shaft 7, which is clamped from both sides and follows the rotation of the cam, and left and right locking pieces 13 and 14 made of flexible elastic bodies are attached on both sides. The original positions of the left and right locking pieces 13, 14, which were stopped after the rotation angle α-length cartridge C shown in FIG. Due to the resiliency of the cartridge, the external cam 11 is reversed in the opposite direction and stopped at its original position, so that the cartridge C also returns to the horizontal position shown in FIG. Depending on the condition of the beard, the cartridge C can be rotated to the right or left, or it can be shaved in a horizontal position while being lowered and rotated depending on the resistance of the beard. In addition, FIGS. 7 and 8 show a device in which a locking ring 17 having a shape in which left and right locking pieces 13 and 14 are connected is used as a locking means. or,
In FIG. 9, a locking tool 18 that can grip the left and right locking pieces 13, 14 from the outside in a groove shape is hooked to the tip. Further, a protruding stopper 16 is attached to the lower end of the outer cam 11 to prevent the cam from rotating more than necessary due to abnormal external force.

又、係止手段は弾性を有する一体構造でもよい。 Alternatively, the rotation shaft 7 may be vertically mounted directly on the central part of the back surface of the cartridge C without using the support stand 6 using double-sided tape or other suitable method. An annular groove 10 in which the rotation shaft 7 is mounted on the support head 8 of the holder 3 and a snap ring 9 can be inserted into the shaft portion protruding to the opposite side.
The rotating shaft 7 is fixed on the center line of the support head 8 so that it cannot escape, and an external cam 11 is formed on the shaft head, and a gap 12 necessary for fitting the snap ring 9 into the support head 8 of the holder 3 is provided. Left and right locking pieces 1 formed by protruding parallel locking means and forming a vertically divided groove extending from the upper end to the base in the center thereof.
3 and 14 are provided. The outer cam 11 having a minimum rotation radius that can abut on both sides of the vertical groove is held between the left and right locking pieces 13 and 14, and the rotation shaft 7 is moved in the direction in which the rotation radius of the outer cam 11 increases.
When the locking piece 13,1 made of an elastic body is rotated,
4 generates an elastic force while being bent from side to side, and when it becomes a counter-resistance force greater than the rotational moment of the cartridge C, it operates in the reverse direction so as to return the rotation shaft 7 to its original position. The shape of the external cam 11 may be any suitable shape, such as an eccentric circle, an ellipse, or a square shape.
Further, the locking means may have an elastic integral structure.
