Referring to Figures 1 to 5, it can be seen that the fixed fastener 4 of the present invention is combined with a predetermined mud removal 2 and a bracket 3, the mud removal 2 has a fixing hole 21, and the middle portion of the bracket 3 has a The bent portion 31, the main structure of the fixing fastener 4 includes at least: a bottom plate 41, a neck portion 42, and a first portion a slot 43 and a second slot 44 and an arcuate slot 45, wherein: the bottom plate 41 extends from the bottom surface of the fixing fastener 4, and the periphery of the bottom plate 41 is at least equal to or larger than the outer edge of the fixing fastener 4; The neck portion 42 is concavely disposed between the bottom plate 41 and the fixing fastener 4; the first slit 43 extends from the top surface of the fixing fastener 4 toward the neck portion 42 and is fixed. An opening is formed at the top of the member 4; the second slot 44 extends from the first slot 43 to the neck portion 42 and forms an angular difference with the first slot 43; and the arcuate slot 45, The fixing member 4 is inserted into the fixing hole 21 of the elastic mud removing 2, and the bottom plate 41 of the fixing fastener 4 is closely attached. At the bottom of the mud removal 2, the first split groove 43, the second split groove 44 and the curved groove 45 are formed on the top surface of the mud removal 2, and then the bent portion 31 of the bracket 3 is forced from the first split groove 43. The first fastening groove 43 and the second cutting groove are inserted into the fixing fastener 4 and are displaced into the curved groove 45 along the second cutting groove 44 to fix the bracket 3 to the mud removing 2; 44 with curved Between the width of 45 and the outer diameter of the bracket 3, it may be a clearance fit (loose fit), an over fit (tight fit), or an interference fit. Therefore, the bracket 3 can be combined and positioned in the arcuate groove 45 without swaying. At this time, the bottom surface and the top surface of the mud removal 2 are respectively closely adhered to the bottom plate 41 of the fixing fastener 4 by the bracket 3, and are fixed between the bracket 3 and the fixing fastener 4.

Please refer to FIG. 6 and FIG. 7 for another preferred embodiment of the present invention. The present embodiment is characterized in that the bent portion 31 of the bracket 3 is slightly flattened as compared with the above-mentioned first to fifth figures. The positioning portion 32 is provided. As can be seen in the figure, the bracket 3 and the bending portion 31 are rod bodies which are integrally extended in diameter. The width of the positioning portion 32 after being slightly flattened is smaller than the diameter of the bent portion 31, but the height is equal to or larger than the diameter of the bent portion 31, and at the same time, the first split groove 43, the second split groove 44 and the curved groove The width of the portion 45 is also equal to or slightly smaller than the diameter of the bent portion 31. Therefore, in the present embodiment, when the bent portion 31 of the bracket 3 is inserted into the first split groove 43, the positioning portion 32 of the bent portion 31 is first. The slots 43 are parallel to each other. After the bracket 3 is moved to the boundary between the first slot 43 and the second slot 44, at this time, between the positioning portion 32 of the bent portion 31 and the second slot 44 The mutually perpendicular state, and then the bent portion 31 of the bracket 3 is the axis, and the bracket 3 is rotated to rotate the positioning portion 32 and the second slot 44 to a horizontal state, so that the bent portion 31 of the bracket 3 can be along the first The second slot 44 enters the arcuate slot 45, and then the bracket 3 is rotated to make the positioning portion 32 and the second slot 44 on the bent portion 31 perpendicular to each other. It is larger than the arcuate groove 45, and the bracket 3 can be firmly fixed inside the fixing fastener 4 in an excessive fit or interference fit.

As shown in FIG. 8 , the first embodiment has a first fixing portion 46 adjacent to the top surface or the bottom surface of the curved groove 45 . When the bracket 3 is firmly fixed inside the fixing fastener 4, the first fixing portion 46 has the auxiliary function of the gain bracket 3 to avoid the arc groove 45 in the shock state; it should be noted that, in the above description, the first fixing The portion 46 is represented by the structure of the convex portion, but it is not limited that the first fixing portion 46 may be a convex portion or a concave portion; when the first portion fixing portion 46 is a concave portion, if the bracket 3 is detached from the curved groove 45 in a shock state, and is slid When the second slot 44 is reached, the bent portion 31 of the middle portion of the bracket 3 interferes with the first portion 46 of the recessed portion, avoiding the bracket 3 having a diameter that is larger than or larger than the second slot 44, and does not easily disengage from the first portion. The second slot 44.

Referring to FIG. 9 and FIG. 10 , the first embodiment has a feature in the first embodiment to the fifth embodiment in that the second slot 44 is disposed adjacent to the top surface and the bottom surface of the curved slot 45 . fixed The structural features of the portion 46 and the second fixing portion 47, the first portion fixing portion 46 and the second portion fixing portion 47 are as described in the foregoing FIGS. 7 and 8 and will not be described herein; however, it should be noted that Between the first fixing portion 46 and the second portion fixing 47, they may be arranged in the same vertical direction (as shown in FIG. 9), or may have a dislocation setting of an X distance (refer to FIG. 10). The purpose is to make it possible to prevent the bracket 3 from coming off the arcuate groove 45 or the second slit 44 during severe or continuous vibration.

Referring to FIG. 11 , the present embodiment is characterized in that the fixing fastener 4 is inserted into the fixing hole 21 of the mud removing 2 from the top to the bottom in a reverse manner to be fixed in the first embodiment to the fifth embodiment. The bottom plate 41 of the fastener 4 is in close contact with the top of the mud removal 2, and the first dissection groove 43, the second dissection groove 44 and the curved groove 45 are formed on the bottom surface of the mud removal 2; and the bracket 3 and the fixing fastener 4 are combined as described above. The process and method are as described above in the first to fifth figures, and are not described here. Therefore, it is found that the fixing fastener 4 can be nested by the top surface of the mud removal 2, or can be reversely inserted from the bottom surface.

In summary, the improved structure of the mud retaining fasteners of the present invention is a novel and progressive creation, and the new patent is filed according to law; however, the above description is only a description of the preferred embodiment of the present invention. Any changes, modifications, alterations or equivalent substitutions extended by the technical means and scope of this creation shall fall within the scope of the patent application of this creation.
