The fact that the outer end face of the first arc protrusion is matched with the inclined cambered surface of the inner wall of the through hole means that as shown in fig. 5, a plurality of sliding ribs 19 are arranged on the inclined cambered surface inner wall of the through hole, the outer end face of the first arc protrusion 6 is matched with the sliding ribs 19, namely, the cambered surface of the outer portion of the sliding ribs is similar to the cambered surface of the outer end face of the first arc protrusion, and therefore the connector 3 can be finely adjusted and rotated on the connector fixing seat 2. The plurality of sliding ribs 19 are uniformly arranged on the inclined cambered surface.

The fact that the inner end face of the first circular arc protrusion 6 is in tangent fit with the outer end face of the second circular arc protrusion 7 to form a circle of tangent line supporting portion means that, as shown in fig. 2, the outer arc surface of the first circular arc protrusion and the inner arc surface of the second circular arc protrusion form a whole circle of tangent line supporting portion at a contact position, when the shaving head is installed into the whole machine, the connector 3 forms a rotation supporting point at the position where the whole circle of contact tangent line is formed to conduct angle fine adjustment, and the effect of comfortable facing shaving can be improved through the angle fine adjustment. After the arc on the inner side of the connector 3 and the arc protruding from the fixing plate 4 form tangency, the tangency position plays a role of a fulcrum, the connector 3 can rotate at multiple angles under the action of the fulcrum of the fixing plate 4, and then the skin contour can be effectively attached, and the angle effect is achieved.

As shown in fig. 5, a first limiting protrusion 8 and a second limiting protrusion 9 are relatively arranged on the inner wall of the through hole 5 of the connector positioning seat 2, as shown in fig. 6, a first limiting groove 10 and a second limiting groove 11 are arranged on two sides of the outer end face of the first arc protrusion 6 on the connector 3, the first limiting protrusion 8 is matched with the first limiting groove 10, the second limiting protrusion 9 is matched with the second limiting groove 11, and the width of the first limiting protrusion 8 is larger than that of the second limiting protrusion 9. The width of the first spacing bulge 8 and the width of the second spacing bulge 9 are all reduced from top to bottom, and the width of the first spacing groove 10 is larger than the width of the uppermost end of the first spacing bulge 8, and the width of the second spacing groove 11 is larger than the width of the uppermost end of the second spacing bulge 9 and smaller than the width of the uppermost end of the first spacing bulge 8. The width difference between the uppermost ends of the first limiting groove 10 and the first limiting protrusion 8 is the same as the width difference between the uppermost ends of the second limiting groove 11 and the second limiting protrusion 9. The first circular arc protrusion 6 is provided with an elastic groove 12 for increasing the elastic force of the inner end surface of the first circular arc protrusion.

As shown in fig. 4, three positioning pieces are arranged on the tool bit lower cover 1, each positioning piece comprises a pressing block 13 for pressing the fixing plate, a limiting block 14 for limiting the rotation of the connector positioning seat, and a reinforcing rib arranged on the limiting block, and three positioning grooves 15 for penetrating through the pressing block and clamping the limiting block are arranged on the connector positioning seat. The width of the pressing block 13 of one of the three positioning members is smaller than the width of the pressing blocks 13 of the other positioning members, and in this embodiment, the pressing blocks 3 of the two positioning members are larger in width, and the pressing blocks 3 of the other positioning member are smaller in width. The connector positioning seat 2 is provided with a stop block 16 for preventing the fixed plate from reversing. The connector fixing seat is screwed into the pressing block 13 in the clockwise direction, the fixing plate 4 is further provided with a deformation groove 20 and an arrow mark 21, and the fixing mode is that the deformation groove 20 and the card main limiting block 14 are rotated by the rotation fixing plate 4, and when the connector fixing seat needs to be disassembled, the rotation fixing plate 4 is screwed out in the direction of the arrow mark 21.
