The specific manner in which the wear member 34 and the support member 18 are fixed relative to each other in the circumferential direction is not limited, and may be fixed by glue or a connecting member, or may be limited by a positioning and clamping structure similar to the clamping member 32.

Referring to fig. 5 and 7, in an embodiment, a positioning buckle structure is disposed between the clamping member 32 and the connecting seat 20, and the supporting member 18 is in snap fit with the connecting seat 20 when the supporting member 18 rotates relative to the connecting seat 20, i.e. when the clamping member 32 does not rotate relative to the connecting seat 20, so as to enhance the stability of the supporting member 18 when the supporting member 18 does not rotate relative to the connecting seat 20.

In this embodiment, the positioning buckle structure includes an elastic buckle 46 disposed on the clamping member 32 and a buckle hole 48 correspondingly disposed on the connecting seat 20 for buckling the elastic buckle 46. The elastic fastening piece 46 has certain elasticity and can deform, so that in the process of relative movement of the clamping piece 32 and the connecting seat 20, the connecting seat 20 can squeeze the elastic fastening piece 46 to deform, and when the elastic fastening piece 46 moves to the fastening hole 48, the elastic fastening piece 46 can be fastened into the fastening hole 48 to form a fastening effect, so that the stability of the supporting piece 18 at the position is enhanced.

It should be understood that the elastic clip 46 may be snapped into the fastening hole 48 after the clip 32 rotates a certain angle relative to the connecting base 20, or may be snapped into the fastening hole 48 when the clip 32 does not rotate relative to the connecting base 20. In the present embodiment, when the clamping member 32 is in the initial state, i.e. not rotated relative to the connecting base 20, the elastic clamping member 46 is buckled into the buckling hole 48, so as to enhance the stability of the supporting member 18 when not rotated relative to the connecting base 20. When the support member 18 is used up and needs to be stored in the accommodating groove 26, if the support member 18 is not turned back to the initial state, the support member 18 will be dislocated from the accommodating groove 26, so that the support member 18 cannot be stored in the accommodating groove 26, and when the user turns back to the initial state, the elastic buckling member 46 automatically buckles into the buckling hole 48 when the elastic buckling member 46 moves to the buckling hole 48, and transmits a buckling sense to the user, so as to prompt the user that the support member 18 has been turned back to the initial position, and at the moment, the support member 18 can be turned back into the accommodating groove 26.

In other embodiments, the positioning buckle structure includes an elastic buckle 46 provided on the connecting base 20 and a buckle hole 48 correspondingly provided on the clamping member 32 for buckling the elastic buckle 46.

The elastic fastening piece 46 comprises an elastic wall 50 and a fastening body 52 arranged on the elastic wall 50, the elastic wall 50 is connected with the clamping piece 32 or the connecting seat 20, and the fastening body 52 can be fastened into the fastening hole 48 or withdrawn from the fastening hole 48, so that a fastening effect or a fastening releasing effect is formed. Specifically, the elastic wall 50 is connected to the clamping member 32, the buckle 52 is disposed on a side of the elastic wall 50 near the connecting seat 20, and the buckle hole 48 is disposed on the connecting seat 20. When the clamping member 32 rotates relative to the connecting seat 20, the buckle body 52 withdraws from the buckle hole 48, the connecting seat 20 can press the buckle body 52, so that the elastic wall 50 deforms, the buckle body 52 is tightly pressed on the connecting seat 20, friction between the connecting seat 20 and the clamping member 32 is increased, and accordingly the risk of rotation of the supporting member 18 relative to the connecting seat 20 in the supporting process is reduced. When the button 52 moves to the button hole 48, the pressure of the connecting seat 20 on the button 52 disappears, and the elastic wall 50 will return to the initial state under the action of the self-elastic force, so that the button 52 is buckled into the button hole 48. When the elastic wall 50 returns to the original state to make the button body 52 snap into the button hole 48, the elastic wall 50 and/or the button body 52 will strike the connecting seat 20, thereby providing a snap-fit feeling for the user to play a role in prompting.

The form of the elastic wall 50 is not limited, and the elastic wall 50 may be automatically formed by forming a through groove in the clip 32 or the connection base 20, or the elastic wall 50 may be fixed to the clip 32 or the connection base 20 by glue or a connection member. In this embodiment, the clamping member 32 is provided with a through slot 54 to form the resilient wall 50.

The specific number of the elastic locking members 46 and the locking holes 48 is not limited, and may be one or a plurality. In the present embodiment, the number of the elastic fastening elements 46 and the number of the fastening holes 48 are plural and correspond to each other, and the plural elastic fastening elements 46 and the plural fastening holes 48 are arranged at intervals around the circumference of the second rotating shaft 30.
