In some alternatives, the metal clip may be coupled to the spin column 11 by a screw thread.

When the first cover body 10 and the second cover body 20 need to be detached and the gap between the first cover body 10 and the second cover body 20 needs to be cleaned, the distance that the metal connecting piece protrudes out of the peripheral wall of the rotary column 11 can be changed by the movable metal clamping piece, for example, the metal connecting piece compresses the elastic piece, so that the rotary column 11 can be moved out of the first shaft hole 21; alternatively, the metal clip is unscrewed from the peripheral wall of the spin column 11 by screwing the metal clip, and then the first cover 10 and the second cover 20 are detached.

Thus, the first cover body 10 and the second cover body 20 can be conveniently detached, and dirt entering the gap between the first cover body 10 and the second cover body 20 can be conveniently cleaned.

Optionally, referring to fig. 1, the metal clamping member is a metal clamp spring 30, and two ends of the metal clamp spring 30 are respectively rotatably connected to the circumferential wall of the rotary column 11, so that the metal clamp spring 30 can rotate between the axial direction and the radial direction of the rotary column 11;

specifically, in this embodiment of the application, the metal snap spring 30 may be an arc-shaped structure, the radian of the arc-shaped structure is similar to or the same as that of the rotary column 11, and when the metal snap spring 30 rotates to the radial direction of the rotary column 11, the metal snap spring 30 surrounds the periphery of the rotary column 11.

Referring to fig. 2 to 4, fig. 2 is a partially enlarged schematic view of a position a in fig. 1, fig. 3 is a partially enlarged schematic view of a position B in fig. 2, and fig. 4 is a schematic view of a structure of a metal snap spring in a cover assembly according to an embodiment of the present disclosure. The peripheral wall of the rotary column 11 is provided with a first boss 112, and when the metal clamp spring 30 rotates to the radial direction of the rotary column 11, the first boss 112 can be clamped with the metal clamp spring 30 to prevent the metal clamp spring 30 from rotating.

Specifically, referring to fig. 3, in the embodiment of the present application, the first boss 112 may be formed integrally with the peripheral wall of the rotary column 11, and in some possible manners, the first boss 112 may also be fixed to the peripheral wall of the rotary column 11 by a connecting member such as a bolt, a screw, or a screw.

Thus, when the metal snap spring 30 rotates to be parallel or approximately parallel to the radial position of the rotating column 11, the metal snap spring 30 is clamped and limited by the first boss 112 and can abut against the hole edge of the first shaft hole 21, so that the axial displacement between the first cover body 10 and the second cover body 20 is limited, and when the metal snap spring 30 rotates to be parallel or approximately parallel to the axial direction of the rotating column 11, the rotating column 11 can be taken out of the first shaft hole 21, so that the first cover body 10 and the second cover body 20 can be conveniently detached, and the gap between the first cover body 10 and the second cover body 20 can be conveniently cleaned.

Specifically, as shown in fig. 4, the anti-separation hook 311 may be formed by bending from an end of the bending portion 31, and may be bent toward a side of the metal snap spring 30.

In this way, after the metal snap spring 30 is mounted on the rotating shaft 11, the anti-drop hook 311 can be engaged with the inner peripheral wall of the rotating shaft 11, so that the displacement of the bent portion 31 in the axial direction of the second shaft hole 111 can be limited, the bent portion 31 can be prevented from moving out of the second shaft hole 111, and the mounting stability of the metal snap spring 30 is improved.

Alternatively, in the embodiment of the present application, the anti-drop hook 311 may be disposed on one of the bent portions 31, or the anti-drop hook 311 may be disposed on both of the bent portions 31. The embodiment of the present application does not limit this.

In some alternative designs, in the embodiment of the present application, the second shaft hole 111 and the first boss 112 are disposed in a staggered manner in the axial direction of the rotary column 11, and the second shaft hole 111 is located on a side of the first boss 112 away from the end surface of the rotary column 11.

Specifically, in the embodiment of the present application, the second shaft hole 111 is located on a side of the first boss 112 facing away from the end surface of the rotary column 11.

It is understood that, in order to facilitate the rotation of the metal clamp spring 30, the second shaft hole 111 and the first boss 112 are also disposed in a staggered manner in the circumferential direction of the rotary column 11.

In the embodiment of the application, through the axial dislocation set with second shaft hole 111 and first boss 112 along column spinner 11, and set up second shaft hole 111 in the one side that first boss 112 deviates from column spinner 11 terminal surface, like this, when rotatory metal jump ring 30, can guarantee as far as that metal jump ring 30 is parallel with column spinner 11's radial maintenance, thereby can increase the hole area along the contact in metal jump ring 30 and first shaft hole 21, increase the lock area promptly, improve the stability of lock.

In a specific example, the quadrant point of the second shaft hole 111 on the side of the end surface of the rotary column 11 and the side wall of the first boss 112 on the side of the end surface facing away from the rotary column 11 are located in the same plane.

It should be noted that, as those skilled in the art can understand, in the embodiment of the present application, the description about the distance has a certain processing error in actual production, and the processing error is negligible to those skilled in the art.
