Description of the Invention: [Technical Field] The present invention relates to a filling material for a root canal groove, especially an injection device relating to a bonding stage, and relating to a dentist, dental restoration, and particularly to an intraoral injection nozzle Medical technique for adhering, invading or filling the root canal groove. [Prior Art] Fig. 1 is a view showing an injection device for filling a liquid material in a root canal disclosed in Patent Document WO2010007257 (Koubi), the device comprising a main body (10, 11), and an intraoral injection nozzle (12) located at the uppermost end of the main body . The injection nozzle (12) is terminated with a line having an outer diameter of S1.5 mm and a length of 28 mm, which is a shape memory material so as to be moldable when needed, and the tip end can be used as a stirring device. The outer layer of the injection nozzle (12) contains at least one circular radial vein (1200, 1201), and the upper end portion (1〇, 11) is shaped by a circular vein, which enables the nozzle position to be fixed at the upper end while being at the axis of symmetry (A) There is a certain degree of rotational flexibility. The injection device can accurately inject the root canal liquid filling to achieve a uniform filling effect without bubble generation. The dentist can also accurately grasp the depth of the root canal groove. However, the root canal length of each patient is different. Therefore, the present invention mainly provides a length that can help the dentist to accurately grasp the root canal of each patient to enhance the therapeutic effect, and will be the desired product of the present invention. 201236651 Extreme disclosure. SUMMARY OF THE INVENTION The present invention is directed to an injection device of the patent document WO2010007257 (Koubi) which proposes an injection device in which the injection nozzle is engraved with a scale for the dentist to measure the depth of the groove, which can accurately conform to the length of the root canal in advance. The scale is located on the outer layer of the injection nozzle, between the circular vein and the tip of the nozzle. The main salient features of the apparatus according to the invention are as follows, each of which may be individual or a combination of the foregoing characteristics, all of which are distinct: the scale is in the form of a colored circular parallel; the annular graduation is 5 mm apart. The device may include a mating nozzle, an automatic agitator coupled to the mating nozzle, and an intraoral injection nozzle disposed at the upper end of the automixer. Another preferred embodiment of the invention is the use of a pinhole optical detector to effectively inspect the root canal. [Embodiment] The embodiments of the present invention are described below by way of specific embodiments, and those skilled in the art can readily understand the other advantages and functions of the present invention from the disclosure of the present disclosure. The embodiments of the present invention are described below with reference to the drawings. It is noted that the following drawings are simplified schematic diagrams, and only the basic concept of the present invention is illustrated in a schematic manner, and only the embodiments of the present invention are illustrated in the drawings. The structure is not drawn according to the number, shape and size of components in actual implementation. The type, quantity and proportion of each component in actual implementation are not limited to the illustrations, and can be changed according to actual design requirements. First, please refer to FIG. 2, FIG. 3a and FIG. 3b, which are diagrams of a filling device for a liquid material filling device for a root canal according to the present invention, comprising a body 10, 11 and an intraoral injection nozzle 12 at the tip end of the body. The intraoral injection nozzle 12 is preferably a plastic material. Specifically, the injection device of the present invention comprises: a matching nozzle 10 fixed to a drug tube containing a mixture of liquid fillings for obtaining a liquid filling, which may be a substrate or a catalyst; An agitator 11 connected to the mating nozzle 10; an intraoral injection nozzle 12 attached to the tip end of the automatic agitator 11. Actually, the mating nozzle 10 is a cylindrical hard plastic of 10 to 25 mm for aiming, fixing or straight molding at the exit of the injection cylinder 13. In Figures 5a and 5b, the injection cartridge 13 generally comprises two portions 13a, 13b, one of which is a substrate and the other of which is a catalyst. When mixed, it can become a liquid filler. The injection cartridge 13 is advanced by a syringe air plug 13c (shown in Figure 5a) or a paint spray 201236651 to allow the substrate and catalyst to flow to the dispensing nozzle 10. In the case where a liquid filling has been prepared, only one side of the cartridge must be used (ie only a portion of the injecting cartridge can be used). The mating nozzle 10 has two tubes 10a, lb attached to the injection cartridge 13. The infusion passes through two tubes to the two sections i3a, 13b. Two tubes 10a, 10b are attached to the bottom of the automatic agitator 11. The automatic agitator 11 is fixed to the tip end of the mating nozzle 10. The automatic agitator consists of a plastic tube with a length of about 20 to 50 mm and a diameter of about 4 to 6 mm. The inside is double-helical 11a for the purpose of uniformly mixing the substrate and the catalyst. The mating nozzle 1 自动 and the automatic agitator Η are known to those skilled in the art and are purchased by the well-known MIXPACK® company as "mixing nozzle (EMBOUTS m6laNGEUR S)", and the injection cartridge 13 is directly filled with liquid filling. In the case of the object, it is not necessary to provide the automatic agitator 11 or to generate a chemical reaction before the injection. If the automatic agitator 11 is formed directly at the exit of the injection cartridge 13, the dispensing nozzle 10 may not be used. The intraoral injection nozzle 12 is attached to the central end of the automatic agitator u to sufficiently uniform the substrate and the catalyst. In Figs. 2 and 4, the main injection nozzle 12 has a pipe line having an outer diameter of g 1.5 mm and a length of mm. In the present embodiment, the injection nozzle is a cylindrical tube having an outer diameter of S 1.5 mm, preferably between 36675 and 0.95 mm 201236651, more preferably 0.8 mm. The length of the cylindrical line is 15 mm, preferably 18 mm. However, the length of the cylindrical line may also be more than a millimeter. The length of the cylindrical line can be such that the injection nozzle 12 is sufficiently long to reach the depth of the root canal as long as the tooth can be treated at any position. In clinical cases, it is conceivable to use a large cone of about 15 mm long with an outer diameter of about 8 mm and a proximal outer diameter of about 5 mm. The injection nozzle 12 has an inner diameter of about 88 mm. The injection nozzle 12 is made of a shape memory material to bend when needed. Although the metal nozzle 12 is preferred, other materials are preferably thermoplastic. The advantage of the metal injection nozzle 12 is that the dentist can effectively and quickly shape the desired opening/closing, adjusting the position of the teeth, and filling the root canal with the hand or the sweetener. In the case of thermoplastic plastics, the dentist must preheat the injection nozzle 12' to create the desired shape. The dashed lines on Figure 2 indicate possible different configurations of the injection nozzle 12. For example, the treatment of the incisors and canines 'the dentist prefers to straighten the injection nozzle 12' and for the treatment of large molars it is necessary to bend the nozzle so that the end or sputum is close to the desired treatment position. In Figs. 3a and 3b, the injection nozzle 12 is directly formed at the tip end of the automatic agitator 11. The outer layer of the left-handed nozzle 12 has at least one circular radial vein 12, and the tip of the 1201 automatic agitator is shaped according to the circular diameter, 201236651 to fix the injection nozzle 12 to the tip while on the axis of symmetry A. There is a certain degree of flexibility in rotation. Referring to Figure 3a, the outer layer of the injection nozzle 12 has at least one circular vein 1200 which is a gate. The tip of the automatic agitator 11 is attached at this gate. In this configuration, the injection nozzle 12 is fixed at the tip end of the automatic agitator 11 while having a certain degree of rotational flexibility on the axis of symmetry A. In another embodiment, see Fig. 3b, the outer layer of the injection nozzle has a circular radial vein 1201, and the tip end of the automatic agitator 11 is shaped according to its circular diameter 1201. The same result was obtained on the outer layers of the injection nozzle 12, and a plurality of circular radial veins were parallel. In accordance with the present invention, and with reference to Figures 2 through 4, the block between the circular veins 1200, 1201 and the distal injection nozzle 12 is engraved with a scale 120. This scale 120 is a parallel colored score, such as black. The spacing between each scale 120 is preferably 5 mm. For example, the injection nozzle 12 has three scales 120 of 5 mm, 10 mm, and 15 mm, respectively, as directed by the dentist. Other types of scales 120 can also be used by those skilled in the art. The scale 120 effectively indicates the depth of penetration of the dentist's nozzle 12 in the root canal and effectively confirms compliance with the prepared length of the gum. In FIG. 4, the injection nozzle 12 is mounted with a pinhole optical detector 201236651
