New description: [New technical field] This creation is a mop head, especially a mop head that improves the fixing degree of the mop. [Prior Art] At present, a mop commonly used in a home or school, as shown in FIG. 5, includes a handle body (not shown) and a mop head 90. The mop head 90 includes a fixed seat 901 and a plurality of a mop 902, the periphery of the fixing base 901 is provided with a plurality of fixing holes 903 and a center thereof is pivotally coupled with a bottom of the handle body, and the fixing hole 903 is used for fixing the mop 902 When the user uses the mop, the mop hair 902 is coupled to the handle body by the mop head 90 for the user to drag the mop hair 902 through the grip body to clean the ground. The existing mop head 90 structure, as shown in the new patent No. M334697 of the Republic of China and the patent No. M393286, the construction of the fixing hole 903 of the mop head 90 is shown in Fig. 6 and Fig. 7, wherein the number M334697® Each of the fixing holes 903A of the mop head 90 has two different inner diameters and a stepped inner wall, and the inner diameter difference is fixed to a mop hair 902 which is disposed therein; and the fixing hole 903B of the M393286 is only The inner wall having a small inner diameter is formed with spaced-apart zigzag protrusions to improve the fixing degree of the fixing holes 903B. However, the fixing holes 903A, 903B of the mop head 90 are inferior in fixing degree. If the mop needs to be spin-dried at a high speed or after a long period of use, the mop hair 902 may be separated or loose from the mop head 90. The phenomenon of making 3 M408339 into the user's inconvenience. All of the above are the ideals of the existing mop head structure. Therefore, the existing mop head structure needs to be further reviewed and a feasible solution is sought. [New content] The creator has improved the existing mop head in view of the shortcomings of the fixed mop head, and the motive head of the present invention is used to solve the aforementioned shortcomings. The length of the present invention is: a mop head comprising a fixing seat and a plurality of mop hairs; wherein the fixing seat is provided with a plurality of fixing grooves around the periphery thereof, the fixing grooves penetrating from the top surface of the fixing seat to the a bottom surface of the fixing base, each of the fixing grooves has a bottom portion, and the bottom portion is formed with a through groove having an inner diameter smaller than an inner diameter of the fixing grooves, and the inner wall surface of the through groove is provided with two engaging portions and two concave portions; The mop hair is composed of a plurality of bristles, and the mop hairs are respectively inserted into the fixing grooves from the through grooves of the bottom surface of the fixing groove, and are fitted and fixed by the nip portions on the corresponding fixing grooves. Preferably, the occlusal portion is composed of a plurality of inserts which are disposed at the bottom of the fixing groove and extend toward the top surface of the fixing groove and the center of the through groove. Preferably, the inserts are model bodies having two curved faces at the top end. Preferably, the occlusal portions are correspondingly disposed, and the two concave portions are respectively disposed between the two occlusal portions. Preferably, the portions of the mop hairs located in the corresponding fixing grooves are glued into a M408339 step by means of adhesive. The technical advantages provided by the mop head of the present invention can achieve the following advantages and effects: The occlusal portion is composed of a plurality of inserts having curved curved surfaces. The inserts extend toward the top surface of the fixing groove and the center of the through groove, which is more fixed than the prior art fixing holes. Significantly improved, and the recesses provide space for the mop hair to be worn, making it easy for the user to assemble the mop hair. _ [Embodiment] The present invention is a mop head 10, as shown in FIG. 1 and FIG. 4, which includes a fixing base 11 and a plurality of mop hairs. As shown in FIG. 1 to FIG. 3 , the fixing base 1 is formed into a disk shape, and a plurality of fixing slots 2 are disposed around the periphery of the fixing base 11 , and the fixing slots 20 are fixed from the fixing seat 11 . The top surface of the fixing base I has a bottom portion, and the bottom fixing groove 20 has a bottom portion, and the bottom portion is formed with a through groove 22 having an inner diameter smaller than the inner diameter of the fixing grooves 20, wherein the through groove 22 is formed by The occlusal portion 221 disposed between the two occluded portions 221 and the recessed portion 222 disposed between the two occlusal portions 221 are formed in a slightly elongated shape; the occlusal portion 221 is composed of a plurality of enemy blocks. The inserting block is disposed at the bottom of the fixing groove 2 and extends toward the top surface of the fixing groove 20 and toward the center of the through groove 22, and the insert block is a wedge body having two symmetric curved surfaces formed at the top end. The recess 222 provides space for the mop hair 40 to pass through. The mop hairs 40 are respectively composed of a plurality of water-absorbent hair ropes. The mop hairs 40 are respectively disposed between the concave portions 222 of the grooves 22 of the fixing grooves 2 and the nip portions 221 . And is fixedly fitted to the occlusal portions 221 5 M408339. Further, as shown in FIG. 4, the mop hair 40 is inserted into the groove 22 from the bottom surface of the fixing groove 20 into the space formed by the two recesses 222 of the groove 22, so that the mop hair 40 can be easily plugged. Into the slot 22, the mop hair 40' is then rotated to make it fit tightly to the nip portion 221 of the slot 22 to achieve the effect of fixing the mop hair 40; finally, from the top surface of the fixing slot 20, The portion of the mop hair 40 located in the corresponding fixing groove 20 is glued, so that the portion of the mop hair 40 located in the corresponding fixing groove 20 is cemented and hardened. [The portion of the hardened mop hair 40 will not be easily obtained from the fixing groove 20 The occlusal portion 221 extends beyond the center of the through groove 22 and extends in the direction of the top surface of the fixing groove 20 so that the strength of the nip portion 221 of the fixing groove 20 to fix the mop hair 40 is greatly improved.
