According to the actual situation, the position of the guide slot 1a and the position of the guide slider 3b can be interchanged, i.e. the guide slot 1a is located on the lower plate 3 and the guide slider 3b is located on the side wall of the base 1.

The lever assembly 2 is located the rear side of the lower supporting plate 3, the lever assembly 2 comprises a first lever 2a and a second lever 2b which are arranged in a crossed mode, the crossed positions of the first lever 2a and the second lever 2b are connected through a rotating shaft 5, and the rotating shaft 5 is fixedly connected with the middle of the lower supporting plate 3. Compared with a single lever, the two levers obviously improve the stress uniformity and the lifting movement stability of the lower supporting plate 3. According to the actual situation, the rotating shaft 5 can be fixedly connected with one lever, and the other lever, the lower supporting plate 3 and the rotating shaft 5 are both rotatably connected.

The guide structure also comprises a guide groove 1a for embedding the end part of the rotating shaft 5, and the guide structure has an auxiliary guide function, so that the stability of the lower supporting plate 3 is further improved, and the strength of the rotating shaft 5 is improved.

The lower end of the first lever 2a is connected with the base 1, and the lower end of the second lever 2b is connected with the base 1 through connecting structures, and the first lever 2a and the second lever 2b can swing and horizontally slide relative to the base 1. The connecting structure comprises a sliding chute 1b positioned on the bottom surface of the inner cavity of the base 1, the lower end part of the first lever 2a and the lower end part of the second lever 2b are both rotatably connected with a roller 6, and the roller 6 is embedded into the sliding chute 1 b; the sliding chute 1b is horizontally arranged, and the longitudinal line of the sliding chute 1b is parallel to the longitudinal line of the lower supporting plate 3; the sliding groove 1b further limits the sliding tracks of the lower ends of the first lever 2a and the second lever 2b, so that the horizontal sliding flexibility is improved, the swinging flexibility and stability are improved, the motion stability of the lower supporting plate 3 is further improved, particularly, the rotating shaft 5 is effectively protected, and the service life of the rotating shaft 5 is prolonged.

An upper pressing piece 4 is arranged at the upper end part of the first lever 2a and the upper end part of the second lever 2b, and a water squeezing space 12 for placing a collodion working head 8 is formed between the upper pressing piece 4 and the lower supporting plate 3. The upper pressing piece 4 comprises an inner shaft fixedly connected with the first lever 2a or the second lever 2b and a sliding sleeve sleeved on the inner shaft, and the structure can improve the sliding flexibility between the upper pressing piece 4 and the collodion working head 8.

The function and the advantage of each part are further explained by explaining the wringing operation process of the collodion mop by utilizing the wringing device of the collodion working head. As shown in FIG. 1, the collodion working head 8 of the collodion mop can be placed in the water at the other side of the cavity of the base 1 for cleaning. Firstly, as shown in fig. 6, the collodion working head 8 of the collodion mop moves from the other side region of the inner cavity of the base 1 to one side region of the inner cavity of the base 1 until the collodion working head 8 is placed in the water squeezing space 12, and the collodion is leaned on the lower support plate 3; the mop rod 9 is positioned between the two upper pressing pieces 4, so that the collodion working head 8 has the advantage of uniform stress. The rear side of the lower supporting plate 3 is provided with a backer 3a, which is beneficial to positioning the collodion working head 8. The lower supporting plate 3 is provided with a water drainage hole, so that the extruded water can flow away conveniently.

Then, as shown in fig. 7, the operator holds the mop rod 9 to push the collodion working head 8 downwards, and the collodion working head 8 pushes the lower support plate 3 to move downwards along the guide direction of the guide structure; the lower supporting plate 3 drives the rotating shaft 5 to move downwards, and the rotating shaft 5 also moves downwards along the side wall of the guide groove 1 a; the rotating shaft 5 forces the rollers 6 connected with the lower ends of the first lever 2a and the second lever 2b to synchronously slide along the longitudinal line direction of the sliding chute 1b, the sliding directions of the lower end of the first lever 2a and the lower end of the second lever 2b are opposite, and therefore the distance between the lower end of the first lever 2a and the lower end of the second lever 2b is increased; because the first lever 2a and the second lever 2b slide horizontally and swing, the distance between the upper end of the first lever 2a and the upper end of the second lever 2b is also increased, the first lever 2a and the second lever 2b drive the upper pressing piece 4 to move in opposite directions, and the sliding sleeve of the upper pressing piece 4 can slide, so that the friction force between the inner shaft and the collodion working head 8 is reduced, and the swing synchronism, flexibility and stability of the first lever 2a and the second lever 2b are improved; the increased distance between the two upper pressing parts 4 can also improve the stress uniformity of the collodion working head 8, so that the collodion working head 8 can be dewatered more uniformly. In the swinging process of the first lever 2a and the second lever 2b, the upper pressing piece 4 is further moved downwards, particularly, the distance between the upper pressing piece 4 and the lower supporting plate 3 is reduced, the upper pressing piece 4 and the lower supporting plate 3 jointly press the collodion working head 8, and water in the collodion working head 8 is gradually squeezed out and drained away. The dehydration amount of the collodion working head 8 is controlled by controlling the downward moving stroke of the lower supporting plate 3. In the above process, the elastic member 7 is gradually stretched.

Finally, people lift the mop rod 9 upwards and/or move the upper pressing piece 4 upwards under the elastic action of the collodion, and under the action of the elastic piece 7, the upper end of the first lever 2a and the upper end of the second lever 2b are gradually folded, the distance between the upper pressing piece 4 and the lower supporting plate 3 is increased until the collodion working head 8 can be taken out from the space between the upper pressing piece 4 and the lower supporting plate 3.

Example two: the structure and principle of this embodiment are substantially the same as those of the first embodiment, and the parts that are substantially the same are not described redundantly, but only different parts are described, and the difference lies in the connection structure: a block is fixed on the bottom surface of the inner cavity of the base 1, and the chute 1b is positioned on the block.
