The process of sliding the pawl 222 over the teeth of the inner ratchet wheel 123 makes the tightening process more laborious, since during tightening of the thread the pawl 222 will abut against and slide over the teeth. In this embodiment, the external thread 211 disposed at the rear end of the plug 220 is a tapered external thread whose diameter increases from the front end to the rear end, so that during the screwing process, the small end of the tapered external thread is inserted into the large end of the tapered internal thread first, and at this time, the tapered external thread can be directly inserted without screwing. Like this, can reduce the number of turns that the user screwed to make the user process of screwing more laborsaving, be more convenient for the user to install each pole section.

Optionally, as shown in fig. 14, 15, and 17, the mop pole may further include a sheath 240, the sheath 240 is sleeved outside the first pole segment 110 and the second pole segment 210, and surrounds the rear end surface of the first pole segment 110 and the end surface of the front end surface of the second pole segment 210 that is located on the outer side, so as to prevent the end surface that leaks outside from contacting the user and causing a bad use experience to the user, and further improve the visual effect of the mop pole.

In one embodiment, as shown in fig. 9 to 13, the first position-limiting structure may be a slot 121 disposed on a sidewall of the first rod segment 110, and the second position-limiting structure may be an insert 221 disposed on a sidewall of the second rod segment 210, where the insert 221 is inserted into the slot 121 to achieve circumferential positioning.

In this embodiment, the rear end of the first rod segment 110 is fitted to the front end of the second rod segment 210. Specifically, the first rod segment 110 may be sleeved outside the second rod segment 210, or the second rod segment 210 may be sleeved outside the first rod segment 110.

When the first pole segment 110 is sleeved outside the second pole segment 210, the slot 121 may be disposed on the inside wall of the first pole segment 110, and the insert 221 is disposed on the outside wall of the second pole segment 210; as shown in fig. 10-13, the insert 121 can be disposed on the exterior side wall of the first pole segment 110 and the insert 221 can be disposed on the interior side wall of the second pole segment 210 when the second pole segment 210 is nested over the first pole segment 110. That is, the insertion groove 121 and the insertion block 221 are respectively disposed on two opposite sidewalls of the first rod segment 110 and the second rod segment 210 after being sleeved.

The opening of the insertion groove 121 may be directed toward the circumferential side, in which case the insertion block 221 is elastically and telescopically coupled to the sidewall of the second rod section 210, and when the insertion block 221 is opposed to the opening of the insertion groove 121, the insertion block 221 is outwardly extended by the elastic restoring force to be inserted into the insertion groove 121.

In one embodiment, as shown in fig. 12 and 13, the end of the insertion groove 121 facing the second pole segment 210 may have an opening from which the insertion block 221 is inserted into the insertion groove 121.

The end of the insert groove 121 facing the second pole segment 210 is the rear end of the insert groove 121, i.e. the insert groove 121 has an opening facing the second pole segment 210 in this embodiment. In this embodiment, since the opening is disposed at the rear end of the slot 121, when the first rod segment 110 is sleeved with the second rod segment 210, the insertion block 221 can be directly inserted into the slot 121 through the opening, the installation process is very convenient, and the insertion block 221 is also very convenient to set.

As shown in fig. 12 and 13, the insertion slot 121 formed in the sidewall of the first pole segment 110 may be an elongated slot, and the insertion block 221 formed in the sidewall of the second pole segment 210 may be an elongated protrusion matched with the elongated slot, so that the elongated protrusion is inserted into the elongated slot, which may improve the reliability of circumferential positioning, and improve the structural stability of the mop pole.

The mop pole provided by the embodiment of the present application may further include a third pole segment, a fourth pole segment, and more pole segments, and the connection manner between every two adjacent pole segments refers to the connection manner between the first pole segment 110 and the second pole segment 210, which is not described herein again.

As shown in FIG. 1, the present application also provides a mop, comprising a mop rod 1000 as described in any of the above embodiments and a mop head 2000, wherein the mop head 2000 is mounted at the end of the mop rod 1000.

The mop may be a collodion mop, a flat mop, a cotton mop, etc., but is not limited thereto.

Because the mop rod provided by any one of the above embodiments is adopted, the mop also has the technical effect corresponding to the mop rod, and the details are not repeated herein.

The above description is only for the specific embodiments of the present application, but the scope of the present application is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present application, and shall be covered by the scope of the present application.
