Description of the Invention: [Technical Field] The present invention relates to a method of manufacturing an interdental brush, and more particularly to a method of manufacturing an interdental brush which is simple in assembly. [Prior Art] Referring to Figure 1 'the prior art interdental brush 1 comprises a handle 11, a brush rod 12 connectable to the handle 11, and a filler 13 covering the handle 11; The handle 11 has a body m, a plurality of openings 112 respectively spaced apart from the body 111, and a through hole ι13 which is open at the end of the body and communicates with the openings 112. The end of the brush bar 12 is inserted into the through hole 113, and the ejector rod 14 extending into the opening 112 is used to extend into the opening 112 by the ejector rod 14 to push the through hole 113. The brush bar 12 is formed in the perforation 113 to form a bending portion 121 of the bending angle ^, and then filled in the perforation i丨3 and the opening 112 by a filler i 3 , that is, The manufacture of the interdental brush 1 is completed. However, although the brush bar 12 is bent by the jack 14 and is bent, there is no click point at the bend of the brush bar 12, so that the brush bar 12 receives the filler 13 even if it is received. Filling, the brush rod 11 can be pulled out even if a little force is applied, so that the brush rod 11 still cannot be stably lost in actual use; furthermore, because the brush #12 is made by staggering the metal wire, Therefore, the brush rod 12 has a certain elastic restoring force after being pushed up. Therefore, when the ram 14 is pushed up, a bending portion 12 of a certain bending angle α is generated, but the bending force is caused by the elastic restoring force. The bending angle ο of the folded portion 121 is smaller, which further affects the combined fixing effect of the brush bar ι2 and the grip 11 and needs to be improved. Due to the above-mentioned conventional structural design factors, there is another conventional design of the interdental brush 2. Referring to FIG. 2, the interdental brush 2 includes a grip 21, a brush rod 22 connectable to the grip 21, And a filler 23 covering the handle 21, wherein the handle 21 has a body 211, and the positioning groove 212 is opened on the body 211 and is externally connected to the body 211. And a through hole 213 communicating with the positioning groove 212, and a positioning hole 214 formed on the body 211 and corresponding to the through hole 213; when manufacturing, the brush bar 22 is respectively disposed. The through hole 213 Positioning in the positioning hole 214, and then pushing the brush rod 22 in the positioning groove 212 by a plunger 24 to generate a bending portion 2, and the bending portion 221 is locked in the positioning groove 212, finally filled with a filler 23 in the positioning groove 212, that is, the manufacture of the interdental brush 2 is completed. However, after the actual use, it is found that although the positioning groove 212 is designed, the f-folding portion 221 can be jammed at the financial position groove 212, thereby increasing the combined effect of the brush bar 22 and the grip 21, thereby effectively improving the foregoing. Conventionally, the elastic restoring force is still unresolved because the brush rod 22 is pushed by the ram 24, so that the angle of the bending portion 221 after the brush rod 22 is topped by the ram 24 is not enough to stabilize. The purpose of the present invention is to provide an interdental brush. The manufacturing method can stabilize and accurately cover the brush bar, so as to increase the fixing effect of the brush bar and the handle. Therefore, the method for manufacturing an interdental brush of the present invention comprises a preparation step, a bonding step, a positioning step, a molding step and the like; wherein the preparation step is provided with a handle and a brush holder holding a plurality of bristles 'The other end of the brush rod is respectively inserted through the clamping hole and the clamping hole and the clamping hole of the handle (and the bonding step), and then the corresponding corresponding mold is matched to use the mold to hold the mold The brush rod is stretched and extended by the pushing of the mold to form a protrusion and the protrusions are protruded into the positioning groove (and the positioning step), and finally a filling is used. The object is wrapped around the positioning groove, and the brush bar can be easily fixed on the handle, thereby improving the fixing effect of the brush bar and the handle. The above and other technical contents, features and advantages of the present invention will become apparent from the following detailed description of the preferred embodiments.

Referring to FIG. 3, FIG. 4 and FIG. 5, a first preferred embodiment of the method 3 for manufacturing an interdental brush according to the present invention comprises a preparation step 31, a bonding step 32, a positioning step 33, a molding step 34, and the like; The preparation step 31 is provided with a handle 41 'and a 6 1374023 brush bar 42 holding a plurality of bristles 421, and the handle 41 has a body 4 ιι, which are respectively spaced apart from the body 411 and connected to the outside. The positioning slot 412 is defined in the body 411 and communicates with the positioning slot 412. The positioning hole 414 is formed on the body 411 and corresponds to the hole 413. A passage 415 corresponding to the through hole 413 is formed in the 412. The bonding step 32 is that the other end of the brush bar 42 is inserted into the positioning slot 412 and the channel 415 through the through hole 413 of the body, and is coupled to the positioning hole 414. The step "" is provided with a plurality of corresponding molds 5, and in this embodiment, the mold 5 is respectively protruded from a protrusion 51 and a groove 52 is formed, and the protrusion 51 is just opposite to the groove 52. The brush bar 42 is pushed into the groove 52 by the protrusion 51, and the brush bar 42 is bent in the groove 52 to form a protrusion. 422, and being held by the protrusion 51 and the groove 52, the bending process of the brush bar 42 can be changed, that is, the rod 42 is thinned and elongated, and is bent to form a protrusion. 422, in order to eliminate the elastic force of the brush bar 42 itself, the protrusion 42 of the brush bar 42 can be prevented from being recovered as the conventional recovery function after the brush bar 42 is separated from the protrusion 51 and the groove 52, so that the The protrusion 422 is more stably protruded into the positioning groove 412, thereby lifting the knot of the brush rod 42 and the handle 41. The second protrusions are formed on the same side, or may be alternately arranged to form a second embodiment (as shown in FIG. 6), and the present embodiment is formed by the protrusions 4 22 in the following embodiment. The same side is 7 1374023. Finally, in the forming step 34, it has a molding machine (not shown) to use the molding machine to inject a filler 43 which is filled in the positioning grooves 412 and The brush bar 42 is covered so that the brush bar 42 can be tightly coupled to the handle 41, and the protrusion 422 and the brush bar 42 are fastened by the through hole 413, the passage 415, the positioning hole 414 and the filler 43.
