The plurality of second bosses <NUM> and the plurality of first bosses <NUM> form the annular groove 22a with both sides enclosed, which can position the connecting ring <NUM> so as to facilitate precise docking between the connecting ring <NUM> and the annular groove 22a. Optionally, the first boss <NUM> and the second boss <NUM> are in arc shapes.

The plurality of first bosses <NUM> are respectively provided with a first slot 22b. Each first slot 22b communicates with the annular groove 22a, and each first slot 22b is provided with a first opening. The first opening is opened on a side wall of the first boss <NUM>, and first openings of the plurality of first slots 22b are in turn arranged along a counterclockwise direction. In some other embodiments, the first openings of the first slots 22b may also be in turn arranged along a clockwise direction. A side wall of the connecting ring <NUM> is provided with first convex blocks <NUM> corresponding to the first slots 22b, and the first slots 22b are used for inserting the first convex blocks <NUM>.

The plurality of second bosses <NUM> are respectively provided with second slots 22c. Each second slot 22c communicates with the annular groove 22a, and each second slot 22c is provided with a second opening. The second opening is opened on a side wall of a corresponding one of the second bosses <NUM>, and second openings of the plurality of second slots 22c are in turn arranged along the counterclockwise direction, that is, arranged in the same direction as the first openings of the first slots 22b, so that the second slots 22c and the first slots 22b jointly act on the connecting base <NUM>. In some other embodiments, the first openings of the first slots 22b may also be arranged in turn along the clockwise direction, while the second openings of the second slots 22c may also be arranged in turn along the clockwise direction. The side wall of the connecting ring <NUM> is provided with second convex blocks <NUM> corresponding to the second slots 22c, and the second slots 22c are used for inserting the second convex blocks <NUM>.

The connecting ring <NUM> is sleeved with the annular groove 22a, the first convex blocks <NUM> clamp to the first slots 22b, and the second convex blocks <NUM> clamp to the second slots 22c. Therefore, the first convex blocks <NUM> and the second convex blocks <NUM> synchronously clamp to the first slots 22b and the second slots 22c to ensure a connection strength of the connecting base <NUM> relative to the second cover body <NUM>, and the second cover body <NUM> is clamped and detached relative to the connecting base <NUM> by rotation, so as to facilitate assembly of the second cover body <NUM> relative to the connecting base <NUM>.

The second convex blocks <NUM> and the first convex blocks <NUM> are respectively arranged on the two sides of the connecting ring <NUM>, the second slots 22c and the first slots 22b are respectively arranged on the two sides of the connecting ring <NUM>, and the plurality of second bosses <NUM> are arranged opposite to the plurality of first bosses <NUM> in one-to-one correspondence, so the plurality of second slots 22c are arranged opposite to the plurality of first slots 22b in one-to-one correspondence, and the plurality of second convex blocks <NUM> are arranged to face away from the plurality of first convex blocks <NUM> in one-to-one correspondence. The second convex blocks <NUM> and the first convex blocks <NUM> are integrated with the connecting ring <NUM>, thus simplifying the structure.

Adjacent two of the first bosses <NUM> are provided therebetween with a first gap, the first convex block <NUM> is in the first gap as the connecting ring <NUM> extends into the upper side of the second cover body <NUM>, and is screwed into the first slot 22b along the clockwise direction through the first opening. Adjacent two pf the second bosses <NUM> are provided therebetween with a second gap, the second convex block <NUM> is in the second gap as the connecting ring <NUM> extends into the upper side of the second cover body <NUM>, and is screwed into the second slot 22c along the clockwise direction through the second opening. The first gap serves as a loading and unloading channel of the first convex block <NUM>, and the second gap serves as a loading and unloading channel of the second convex block <NUM>. When it is necessary to connect the second cover body <NUM> to the connecting base <NUM>, the connecting base <NUM> is extended into the upper side of the second cover body <NUM> and the connecting base <NUM> is rotated in the clockwise direction or the second cover body <NUM> is rotated in the counterclockwise direction under a man-made force. The first convex blocks <NUM> are clamped to the first slots 22b through the first gaps and the first openings in turn with the rotation of the connecting ring <NUM> relative to the second cover body <NUM>, while the second convex blocks <NUM> are clamped to the second slots 22c through the second gaps and the second openings in turn with the rotation of the connecting ring <NUM> relative to the second cover body <NUM>, so that the second cover body <NUM> is clamped to the connecting base <NUM>. When it is necessary to detach the second cover body <NUM> from the connecting base <NUM>, the connection base <NUM> can be rotated in the counterclockwise direction or the second cover body <NUM> can be rotated in the clockwise direction under a man-made force. The first convex blocks <NUM> are detached from the first slots 22b through the first openings and the first gaps in turn with the rotation of the connecting ring <NUM> relative to the second cover body <NUM>, while the second convex blocks <NUM> are detached from the second slots 22c through the second openings and the second gaps in turn with the rotation of the connecting ring <NUM> relative to the second cover body <NUM>, so that the second cover body <NUM> is detached from the connecting base <NUM>. Furthermore, a detachable connection of the second cover body <NUM> and the connecting base <NUM> is realized. Compared with the way of a thread connection between the second cover body and connecting base in the prior art, the detachable connection structure of the second cover body <NUM> and the connecting base <NUM> is simplified in this embodiment, thus reducing a processing cost of the second cover body <NUM> and the connecting base <NUM>. Therefore, an overall cost of the cover body component <NUM> is reduced.

The first convex blocks <NUM> are clamped to or detached from the first slots 22b with the rotation of the connection ring <NUM> relative to the annular groove 22a, and the second convex blocks <NUM> are clamped to or detached from the second slots 22c with the rotation of the connection ring <NUM> relative to the annular groove 22a, so that the second cover body <NUM> can be detachable relative to the connecting base <NUM> and the handle <NUM>, which is convenient to replace the sealing ring <NUM>.

In the above embodiments, the description of each embodiment has its own emphasis. For the parts not detailed in one embodiment, please refer to the relevant descriptions of other embodiments.
