As described above, since the first hooking member 20b and the second hooking member 20a can be moved relative to each other, even if the mop M is washed and the mop M shrinks, the first hooking member 20b. The mop M can be easily attached by changing the distance between 20b and the second hooking member 20a.

Therefore, even if the mops M are different in size, the size of the mops M corresponds to the size of the mops M as long as the first hooking members 20b and the second hooking members 20a can be moved. By moving the first hooking member 20b and the second hooking member 20b in this manner, various mops M can be attached. Accordingly, even when the user uses several types of mops M having different sizes, it is not necessary to prepare the mop heads 10 corresponding to the number of types of the mops M. Therefore, even if the mop head 10 is stored with the mop handle H attached, only one mop handle H and the mop head 10 can be stored, and the storage space can be effectively utilized for other purposes.

Further, the second hooking member 20a is attached to the cover body 21.
Since only the first hooking member 20b is moved to the second hooking member 20a side without changing its position, the engaging portion 47 of the hooking member 27 and the second hooking member 20a are locked. The engagement portion 40 can be reliably engaged.

The mop head of the present invention is not limited to the above-mentioned embodiment, and it goes without saying that various modifications can be made without departing from the gist of the present invention.

In the present embodiment, the cover body 21, the first hooking member 20b, the second hooking member 20a and the stopping member 27.
Each of these are integrally molded, for example,
In the first hooking member 20b, each of the first tip portion 35, the fixing portion 36, and the positioning portion 37 may be molded separately and finally assembled to the first hooking member 20b. That is, if the functions of the cover body 21, the first hooking member 20b, the second hooking member 20a, and the restraining member 27 can be maintained, the manufacturing process and method are not limited to the present embodiment, and various manufacturing methods are possible. It can be manufactured in.

Further, in the present embodiment, the four first screw insertion holes 24a, 24 are formed in the first retaining member 20b.
a, 24a, 24a and four second screw insertion holes 24b,
Although the holes 24b, 24b, and 24b are drilled, the holes are not limited to those having two pairs of holes, and the first hooking member 20b is not limited thereto.
Alternatively, a pair of elongated holes having a length in the contact / separation direction of the second retaining member 20a may be used. That is, the first hooking member 20b and the second hooking member 20a are located on the same row in the contacting / separating direction and are adjacent to each other, and the adjacent first screw insertion hole 24a and second screw insertion hole 2 are provided.
You may make 4b one long hole. With this, the base material 2
First hooking member 20b and second hooking member 20a for 1
Can be adjusted.

Further, the pivotal support groove provided in the first hooking member 20b is the first pivotal support groove 23a, 23a and the second pivotal support groove 23.
It is not limited to the one in which two sets of grooves b and 23b are formed, and two or more sets of grooves may be formed. If two or more sets of pivotal grooves are formed, mops M of different sizes can be attached.

When forming two or more sets of pivotal grooves,
The distance between the pivot grooves is approximately twice the displacement amount (position change amount) for displacing the first retaining member 20b (the displacement amount for displacing the first retaining member 20b is half the distance between the pivot grooves). given that,
Each of the first hooking member 20b and the second hooking member 20a can be evenly displaced, and the mop M can be prevented from being unevenly attached. Therefore, when a plurality of pivotal support grooves are formed, the pivotal support grooves located at an interval twice the amount of displacement for displacing the first retaining member 20b with respect to the pivotal support groove that originally supported the support shaft 22. Even if the mop M is pivotally supported, the first hooking member 20b and the second hooking member 20a can be uniformly displaced, and the mop M can be prevented from being attached unevenly. In this case, if the displacement amount of the restraining member 27 is made large so that the engaging portion 40 can be largely displaced, even if the restraining engaging portion 40 is displaced by changing the position of the second retaining member 20a. The engagement portion 47 and the restraining engagement portion 40 can be disengaged.

Further, the spring body 46 of the restraining member 27 is not necessarily limited to the one attached to the other end of the restraining member 27, and a separate spring, for example, a compression coil spring is locked to the cover body 21. It may be sandwiched between the piece 33 and the other end of the blocking member 27. That is, the stopping member 2
7 may be restored to a predetermined position by the spring force so that the engagement between the engaging portion 47 of the restraining member 27 and the restraining engaging portion 40 of the second retaining member 20a can be maintained.

[0040]

As described above, in the mop head according to the present invention, even if the mop is shrunk due to repeated cleaning, the pair of hook members are relatively moved so as to bring the pair of insertion portions into contact with and separate from each other. Since the position can be changed, the mop can be attached by bringing the pair of insertion parts into and out of contact with each other so as to correspond to the arrangement of the mounting bag part of the mop.

Further, even when attaching mops of different types or sizes, the position of the pair of latch members can be relatively changed so that the pair of insertion portions are brought into contact with and separated from each other, so that the pair of latch members can be moved relative to each other. Within the possible position of the stop member,
Various mops can be attached regardless of type and size. Therefore, the user does not need to carry a number of mop heads according to the type of mop, and can effectively use the storage space that has previously stored a plurality of mop heads and mop handles.
