[0134] Reference Figures 28 to 30 The mounting portion 70 can be detachably coupled to the head portion 10 (see Figure 6 The mounting portion 70 can be connected to the connecting plate 152 of the rear cover 15 (see Fig. 22 ) can be detachably combined. Fig.29 and Fig.30 1 is a diagram showing the engaged state of the mounting portion 70. The engaged state (latched state) can be referred to as a locked state (locked state) or a coupled state (coupled state). Fig.28 2 is a diagram showing an unlatched state of the mounting portion 60. The unlatched state may be referred to as an unlocked state or an uncoupled state.

[0135] Refer to Fig.28 and Fig.29, the top hook 771 can move in the up-down direction by the top spring 773. If the top hook 771 is located between the plate 71 and the cover 72 and becomes hidden, the top spring 773 can be compressed. If the user places the mounting portion 70 on the base plate 151 in a state where the top hook 771 is hidden, the top hook 771 can protrude to the outside of the mounting portion 70 due to the restoring force of the top spring 773 and be stuck in the coupling groove of the coupling plate 152.

[0136] Refer to Fig.30 and Fig.29 If the knob 742 is moved left and right, the first hook 738 and the second hook 739 can be in an engaged state or an engaged state. The knob 742 can be moved left and right in the slot 72S. If the knob 742 is moved left and right in the slot 72S, the pin 741 can be moved in the pin hole 733.

[0137] Reference Fig.29 , if the knob 742 moves to the left, the pin 741 moves along the first path P from the first path P1 and the second path P2, and the slider 73 may rise relative to the combined plate 71 and the cover 72. At this time, the lower ends of the first stopper 727 and the second stopper 728 may contact the first hole 731 and the second hole 732 of the slider 62, thereby limiting the movement of the slider 73. If the movement of the slider 73 is limited by the stoppers 727 and 728, the slider 73 may rise as the first spring 734 and the second spring 736 are compressed. As the slider 73 rises, the first hook 738 and the second hook 739 may be located between the plate 71 and the cover 72 (hidden state), and the mounting portion 70 and the rear cover 75 become a lock release state, so that the user can remove the mounting portion 70 from the head 10.

[0138] Refer to Fig.29 and Fig.30 , if the knob 742 moves to the right, the pin 741 can move from the first path P1 along the second path P2. At this time, the slider 72 can be lowered by the restoring force of the first spring 734 and the second spring 735. If at this time, the upper ends of the first stopper 727 and the second stopper 728 are stuck in the first hole 731 and the second hole 732, the movement of the slider 73 can be restricted. As the slider 73 descends, the first hook 738 and the second hook 739 can protrude in the radial direction of the mounting portion 70 through the first cutout portion 7291 and the second cutout portion 7292, and are inserted into the coupling groove of the coupling plate 152. As a result, the mounting portion 70 and the rear cover 15 are in a locked state, so that the user can couple the mounting portion 70 to the head 10.

[0139] Fig.31 2 is a diagram showing the locking sequence of the mounting portion 70. Fig.31(a), the user can place the mounting portion 70 on the base plate 151 in a state where the top hook 771 is hidden. In this case, the top hook 771 can protrude to the outside of the mounting portion 70 by the restoring force of the top spring 773 and be stuck in the coupling groove.

[0140] Reference Fig.31 (b) and Fig.31 (b), after the user first engages the top hook 771, the user can engage the first hook 738 and the second hook 739 by operating the button 74. After engaging the top hook 771, the user can move the knob 742 to the right to make the first hook 738 and the second hook 739 stuck in the engagement groove. In this way, the mounting portion 70 can be engaged with the head 10.

[0141] When separating the mounting part 70 from the head 10 , the user can move the knob 742 to the left to switch to a locked release state in which the first hook 738 and the second hook 739 are separated from the coupling groove, and then pull the mounting part 70 downward to separate the mounting part 70 from the head 10 .
