Description of the Invention: [Technical Field] The present invention relates to a manufacturing method, particularly a method of manufacturing an interdental brush. [Prior Art] Referring to Figure 1, the interdental brush 1 comprises a handle 11, a brush rod 12 connectable to the handle 11, and a filler 13 covering the handle ii, wherein The handle 11 has a body m, a plurality of openings 112 respectively spaced apart from the body 111, and a through hole 113 opening at one end of the body U1 and communicating with the openings 112. The brush bar 12 is inserted into the through hole 113 at the end, and the ejector 14' extending into the opening 112 is used to extend into the opening u2 by the ejector 14 to push the hole 113 into the hole 113. The brush bar 12 is such that the brush bar 12 forms a bending portion 121 of the bending angle α in the through hole 113, and then is filled in the through hole 113 and the opening 112 by using a filler 13 to complete the interdental space. Brush] manufacturing. 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 u can not be stably lost in actual use; in addition, since the brush rod 12 is formed by staggering a metal wire, Therefore, after the brush rod 12 is pushed up, it has a certain elastic restoring force, so that the top rod Η is pushed forward to generate a certain bending, but the elastic restoring force affects the brush rod! 2 The kidney folding angle α becomes smaller, which further affects the brush. 201124116 The combination of the rod 12 and the grip u has a need to be improved. Since the conventional structural design factor is just described, there is another known ax meter for the interdental brush 2. Referring to FIG. 2, the interdental brush 2 includes a grip 21, and a brush rod connectable to the grip 21. 22, and a filler 23 covering the handle 21; wherein the handle 21 has a body 211, and a positioning groove 212 is formed on the body 211 and communicated with the external body 211. a through hole 213 which communicates with the positioning groove 212, and a positioning hole 214 which is formed on the body 211 and corresponds to the through hole 213. When manufacturing, the brush bar 22 is respectively placed on the through hole. Positioning in the positioning hole 214, and then pushing the brush bar 22 in the positioning groove 212 by a ejector 24 to generate a bending portion 221, and the bending portion 221 is locked to the positioning groove 212. Finally, a filler 23 is finally used to fill 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 to be clamped to the positioning groove 212 by the bending portion 221, the combination of the brush bar 22 and the handle 21 is increased. Effectively improving the aforementioned conventional deficiency, but since the elastic restoring force of the brush bar 22 when pushed by the ram 24 is still unresolved, the brush bar 22 is topped by the ram 24 and the angle of the bending portion 221 is It is not enough to firmly clamp the positioning groove 212, so the combined fixing effect of the brush bar 22 and the grip 21 is relatively affected, and there is still room for improvement. • #图图 3 'again — a conventional interdental brush 3 design, the interdental brush 3 includes a handle 31, a brush bar 32 connectable to the handle 31, and a cover on the handle 31 a filler 33; wherein the handle 31 is provided with a through hole 3 _ 3 and a plurality of positioning grooves 312, and the positioning grooves 312 are not connected to the 5 201124116 perforation 3U. When the brush bar 32 is inserted, the cover portion 314 is pressed, and the brush bar 32 is filled in the positioning groove 312 with respect to the squeezed position 'final reuse' filler 33 That is, the manufacture of the interdental brush 3 is completed; however, the covering portion 314 is squeezed and the brush rod 32 is covered therein, but the covering portion 314 is made of a plastic material, and the brush rod 32 is The metal material is used. Therefore, when the covering portion 314 is pressed, the covering portion 314 does not effectively deform the brush 32, and the brush rod 32 is easily recessed in the covering portion 314. The inner portion causes the brush bar 32 to be effectively squeezed, and the brush bar 32 cannot be covered when the filler 33 is filled, resulting in the interdental space of the brush bar 32. The pulling force of the grip 31 is easily detached, it could be improved. SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a method of manufacturing an interdental brush which can stabilize and accurately position the brush bar to improve production efficiency and reduce production cost. Therefore, the manufacturing method of the interdental brush of the present invention comprises a preparation step, a bonding step, a positioning step, a molding step and the like; wherein the positioning step is provided with a punching device, and the punching device is used to expose the positioning groove The brush bar is stamped such that a plurality of expansion zones are formed on the brush bar, and the maximum outer diameter of the expansion zones is larger than the perforation aperture, so that the brush bar can be stably positioned in the positioning groove, and finally matched The filling filled by the molding step is coated to make the clamping of the brush bar more stable, and the detachment of the brush bar is prevented from being used. 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. Before the present invention is described in detail, it is noted that in the following description, similar elements are denoted by the same reference numerals. Referring to FIG. 4 and FIG. 5, a first preferred embodiment of the method 4 for manufacturing an interdental brush according to the present invention comprises a preparation step 41, a bonding step 42, a positioning step 43 and a molding step 44, etc., wherein the preparation is prepared. The step 41 is provided with a handle 51 and a brush bar 52 for holding a plurality of bristles 521. The handle 51 has a body 511 spaced apart from the plurality of positioning slots 512, which are respectively disposed on the body 511 and communicated with each other. a through hole 513 is formed in the body 511 and communicates with the positioning slot 512, and a positioning hole 514 is defined in the body 511 and corresponding to the through hole 513, and the foregoing may be additionally provided according to actual use. There is a marked area 515 (i.e., as shown in Figure 7) that is displayed as a trademark or other pattern. Continuing with the foregoing, the bonding step 42 is performed by the other end of the brush bar 52 being inserted into the positioning slot 512 through the through hole 513 of the body 511, and is coupled to the positioning hole 514; The stamping device has a stamping device (not shown), and in the embodiment, the stamping device has a plurality of molds 431 (not shown in the figure) with respect to the positioning grooves 512. The mold 431 stamps the brush rod 52 exposed at the positioning groove 512 to form a plurality of expansion regions 522, and the maximum outer diameter A of the expansion regions 522 is larger than the aperture a of the through hole 513, so that the brush rod 52 is expanded. 7 201124116 The area 522 is stably positioned in the positioning slots 512, as shown in FIG. 6 and FIG. 7. Referring to FIG. 8 , finally, the molding step 44 has an injection molding machine (not shown) for injecting a filler 53 into the positioning groove 512 by using the injection molding machine. The brush bar 52 is disposed such that the brush bar 52 and the positioning groove 512 can be tightly coupled to the handle 51, and the brush bar 52 having a flat shape is fastened by the through hole 513, the positioning hole 514 and the true filling 53. The card is limited, and does not cause looseness or rotation during use. Of course, if the marking area 515 is designed in this embodiment, the filling area 53 is not covered when the filling 53 is filled. Instead, the marked area 515 will be highlighted, thus completing - the complete interdental brush 5 is manufactured. Therefore, in the manufacturing process of the interdental brush 5, the design of the through hole 513 and the clamping hole 514 of the handle 5 can be used in the positioning step 43 to directly expose the punching device to the same. The brush rod 52 at the positioning groove 512 is stamped into an expansion region 522 such that the maximum outer diameter a of the expansion region 522 is larger than the hole of the perforation 513; therefore, under the dual action of the expansion regions 522, The expansion region 522 cannot be detached from the perforation 513, and the brush bar 52 is effectively clamped in position by the fact that the expansion regions 521 are mutually engaged. Finally, the filler 53 is used to fill the molding step 44. When the groove 512 is equalized, the brush bar 52 is wrapped therein and is tightly coupled with the positioning groove 512 and the handle 51 to avoid detachment loss when the brush bar 52 is used. Referring to FIG. 9 and FIG. 1A, the second embodiment of the present invention differs from the previous embodiment in that the end of the through hole 513 is formed in a push-out shape, and the through hole 513 is located near the positioning groove 512. The aperture a is smaller than the aperture a' of the through hole 513 communicating with the outside. Even if the brush rod 52 is inserted through the aperture a, the aperture 331 is inserted into the aperture y, and the aperture is received. a tight compression effect, which is closely combined with the perforation 513, so that when the brush bar 52 is punched into the expansion regions 522 through the next process, not only the effect of the card positioning on the positioning grooves 512 but also the hole is received. φ Diameter 3 is effective against the impact, and after being covered by the filler 53, the clamping groove 512 and the grip 51 are more closely coupled with each other, so as to avoid the external force between the teeth being easily pulled out of the grip. The situation of 51 is generated, and the fixing effect of the brush bar 52 and the grip 51 is greatly improved. In summary, the method for manufacturing the interdental brush of the present invention, in the positioning step, punches the brush bar into a plurality of expansion zones, and the expansion zones are firmly stuck in the positioning groove, and finally utilized in the molding step. A filler is filled, and the filler can just cover the brush bar, and the brush bar is further stabilized to prevent the use of the brush bar to cause detachment. However, the above description is only for the purpose of illustrating the preferred embodiments of the present invention, and is not intended to limit the scope of the embodiments of the present invention.
