For example, in one existing drain apparatus, a container is communicated with a drain pipe through an outflow port, a drain plug is provided near the outflow port, the drain plug is connected to one end of an operating lever such as a lever member, and the other end of the lever member is connected to a downwardly extending lever member, whereby the drain plug can be moved between positions closing and opening the outflow port by operating the lever member, and water storage or drainage of the container such as a bathroom sink, a bathtub, a washbasin or a hand sink is achieved.

See chinese patent document CN103967082B, which discloses a drain plug linkage comprising: a drain plug; the pull rod assembly comprises a pull rod and a connecting rod which are in operable connection with each other; a lever member; and an engagement mechanism. One of the connecting rod and the lever member has a plurality of through holes and slidably mounts an engagement mechanism, the other of the connecting rod and the lever member is configured to pass through one of the through holes and has a plurality of circumferential ribs spaced apart axially and a groove defined between the circumferential ribs, the engagement mechanism is configured to prevent the other of the connecting rod and the lever member from moving axially relative to the through hole when slid into a position engaging the groove. However, this patent also has the following technical problems: firstly, assuming that a plurality of through holes are formed in a connecting rod, a lever part penetrates through any one of the through holes, when the height of the lever part needs to be adjusted, the lever part needs to be firstly slid upwards to be connected with a mechanism, then the lever part is taken out of one through hole, then the lever part is inserted into the other through hole, finally the lever part is clamped by the mechanism which is slid downwards, if the height is still unsuitable, the lever part needs to be operated again according to the steps, and the height adjustment process is complex, inconvenient and not fast; assuming that a plurality of through holes are formed in the lever member, the connecting rod passes through any one of the plurality of through holes, and when the transverse position of the connecting rod on the lever member needs to be adjusted, the adjusting mode is similar to the previous adjusting mode, and the transverse position adjusting process is also tedious, inconvenient and not rapid; the second water draining plug linkage device needs to frequently operate a pull rod assembly, a connecting rod is driven to ascend or descend through the pull rod, a lever piece is driven to ascend or descend through the connecting rod, water storage or water draining of a container is achieved through the lever piece, and the connecting rod or the lever piece is slidably mounted on the connecting rod or the lever piece, and the lever piece can form certain thrust for the connecting mechanism in the swinging process, so that the connecting mechanism is easy to loosen after the lever piece swings for a long time or for many times, and the problem that grooves between the connecting mechanism and the circumferential ribs are loosened is solved, so that the connecting stability of the connecting rod or the lever piece and the connecting mechanism is not good.

See chinese patent document CN110984311a, which discloses a drain plug linkage comprising: the drain plug is accommodated at the upper end of the drain pipe, the pull rod assembly is linked with the operating rod, the operating rod is linked with the drain plug to move up and down, the pull rod assembly comprises a pull rod and a connecting sleeve, the pull rod is linked with the connecting sleeve, a plurality of clamping portions are concavely arranged on the operating rod at intervals, a plurality of positioning portions with openings are arranged on the connecting sleeve at intervals, and one clamping portion of the operating rod selectively penetrates through one opening to be clamped in the corresponding positioning portion. Although the pull rod assembly or the operating rod does not need to be completely pulled out when the positions of the pull rod assembly and the operating rod are adjusted, the patent needs to be clamped with the clamping-in part of the operating rod by utilizing the opening positioning part of the connecting sleeve; because the drain plug linkage device needs to frequently operate the pull rod assembly, the operating rod is driven to swing up and down through the pull rod assembly, the problem that the connection between the operating rod and the pull rod assembly is loose is easily caused after the operating rod swings for a long time or a plurality of times, and therefore the connection stability of the operating rod and the pull rod assembly is not good enough.
