If there is a chemical formula in this case, please disclose the chemical formula that best shows the characteristics of the invention: IX. Description of the invention: 4 200819102 Technical Field of the Invention The present invention relates to a mop cleaning cloth fixing structure, in particular to a cleaning cloth. And a tightly fixed structure. [Prior Art] The fixed structure of the mop cleaning cloth of the present invention can be roughly divided into two types of a snap-fit type and a clip-on type. The more common clip-on type fixing structure is generally present because of the advantages of simple assembly and simple components. On the market. It is reported that today's clip-on dust mop mainly needs at least a base 1 and a handle 2 extending upward from the top of the base 1 (as shown in Fig. 1); wherein the top of the base 1 is located around the handle 2 The positioning portion 3 is provided with a plurality of positioning portions 3 for fixing the ends of the cleaning cloth C so as to be tightly wrapped on the base 1. In more detail, the positioning portion 3 has an internal space inside (for example, As shown in FIG. 2, the top of the space is provided with an elastic piece 4 which is aligned with the top of the base 1. The surface of the piece 4 is provided with a serrated opening formed by a plurality of teeth 5 (such as the first one). As shown in the figure), when the ends of the cleaning cloth C are to be fixed, it is necessary to apply force to the elastic sheet body 4 through the cleaning cloth C, so that the tooth portions 5 on the sheet body are deformed by force, and the positioning portion is simultaneously opened. The internal space of 3 causes the end of the cleaning cloth C to be pushed into the space (as shown in Fig. 2). However, the above-mentioned mop cleaning cloth fixing structure can quickly and easily fix each end of the cleaning cloth C to the positioning portion 3 of the base 1; 5 200819102 However, in actual use, the cleaning cloth is fixed by the tooth portion 5. The shortage of C is unable to counteract the force generated between the cleaning cloth C and the ground, causing the cleaning cloth to be detached from the positioning portion 3, and it is easy to pinch the finger of the person. The reason is that the general elastic piece 4 is made at the time of its creation. When the plurality of teeth 5 of the surface are formed by cutting or die punching, the teeth are surrounded by a gap E (shown in FIG. 1), and if the gap D is too large (more than twice the cleaning) Thickness), the teeth 5 do not clamp the cloth C in a clamping manner, but only reset and close the internal space to limit the cleaning cloth, without any pinching effect, if the gap D is small (small cleaning) If the cloth C is twice as thick, the elasticity of the elastic sheet 4 cannot be completely focused on the cleaning cloth C, and the clamping force of the tooth portion 5 applied to the clear C is insufficient, and the rubbing force with the cleaning cloth C and the ground cannot be generated. Relative resistance. Therefore, how to make the elastic piece tooth portion tightly clamped to the cloth enough to resist the friction generated by the cleaning cloth and the ground is a subject of research. SUMMARY OF THE INVENTION The main object of the present invention is to provide a mop-clearing fixing structure in which each tooth unit constituting a serrated opening extends a length toward an inner space of the positioning portion to form a pinch portion. The elastic force is fully focused on the cleaning cloth, and the cleaning is tightly fixed to the base by the clamping of the respective teeth. And in the force road friction used in the molding side (such as cloth C clear C retreat to the force and clean the cloth to clean the cleaning cloth to make the cleaning cloth use 6 200819102. When using the finger to insert the dust cloth, it is not easy In order to achieve the above object, the present invention provides a mop cleaning cloth fixing structure for fixing a cleaning cloth to a mop, the structure comprising: a base, which is provided with a working bottom surface and a top and a plurality of The positioning portions are respectively disposed on at least four corners of the top portion, wherein each positioning portion is embedded on the base, the interior thereof is hollow, and the top end is provided with an elastic sheet, and the thin® sheet is provided with The plurality of teeth form a serrated opening, and each of the tooth portions respectively extends toward the positioning portion to extend the clamping portion, so that the tooth portions are deeply engaged with the cleaning cloth to increase the clamping force of the elastic sheet, thereby preventing cleaning The frictional force of the cloth and the ground. The mop cleaning cloth fixing structure according to the present invention, wherein the extending portion of the tooth portion is such that the elastic force of the elastic sheet body is completely Φ converted The clamping force of the toothed portion on the cleaning cloth is such that the cleaning cloth is tightly fixed on the base, and the extending portion of the downwardly extending tooth portion extends to the inner space of the base to at least 1 In two places, the user can prevent the finger from being pinched by the clamping portion when the cleaning cloth is inserted, thereby adding a safety effect. According to the mop cleaning cloth fixing structure of the present invention, the top of the base is provided with a multi-directional swinging expansion and contraction. 7 200819102 [Embodiment] The present invention is directed to the above-mentioned objects, the technical means and the remaining functions, and a preferred embodiment is described below with reference to the following: The cleaning cloth of the present invention can be used.
