the connection between the first upper groove 71 and the first lower groove 72 is set as a dividing line 8;

the first lower groove 72 is designed to be deep and shallow.

In some alternative embodiments, the first upper groove 71 is designed to be shallow and deep up and down, so that the first upper groove 71 and the first lower groove 72 at the dividing line 8 are disposed at an obtuse angle therebetween.

In the embodiment of the application, the contact area between the thumb and the middle finger and the handle main body 1 during vertical three-finger clamping can be increased by dividing the first groove 7 into the first upper groove 71 and the first lower groove 72, and the contact angle is limited to ensure that the clamping angle of the thumb and the index finger accords with the ergonomics, so that the smoothness and the comfort degree of the vertical clamping can be ensured, and meanwhile, the accommodating space of the index finger and the first knuckle finger of the thumb can be provided during the transverse clamping process.

By controlling the grooving depth between the first upper groove 71 and the first lower groove 72, respectively, the boundary line 8 at the contact point between the first upper groove 71 and the first lower groove 72 can be the deepest point of the two, and an obtuse angle groove is formed at the boundary line 8, and the obtuse angle groove can accommodate and abut against the fingers of the thumb and the middle finger in the vertical three-finger clamping stage (when the index finger is positioned on one side of the second gripping surface 6), so that the thumb and the middle finger are prevented from sliding back and forth in the direction of the cutter head in the shaving action, and the use stability of the gesture is improved; or in the other transverse clamping (other fingers are on the side of the smooth curved block, the thumb is on the side of the second gripping surface), when the index finger is positioned on the bearing plane 43, after bending the index finger, the finger belly of the first knuckle can be attached to the obtuse angle groove, at the moment, the middle finger is bent, the finger head of the middle finger is abutted against the first lower groove 72 and is close to the edge of the first gripping surface 5 (the side of the convex plane 11 hereinafter), the first knuckle of the middle finger is placed in the first lower groove 72, the second knuckle of the middle finger is abutted against the convex curved surface 41, the integral contact surface of the finger and the handle main body 1 is increased, and the vertical clamping posture close to the gripping is formed, so that the stability in use is improved.

Meanwhile, due to the upper-deep-lower shallow design, the width of the upper end of the convex curved surface 41 is smaller than that of the lower end, so that the thumb can be conveniently and transversely clamped (the thumb is on one side of the smooth curved block and other fingers are on one side of the second gripping surface), the friction force is small when the thumb can be placed at the position where the upper half part of the convex curved surface 41 is narrower, the thumb can be matched with the index finger and the middle finger which are positioned on the second gripping surface 6, the whole handle can be flexibly rotated, and the unused clamping posture can be rapidly switched; when the thumb is placed in the wider position of the lower half of the convex curved surface 41, there is enough supporting surface to stabilize the lateral holding posture at this time.
