[0016] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. The embodiments in the basic utility model and all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1 , 2 As shown in the figure, the shell 3 is provided with a platform 1 for placing the taper trimming unit 2 on the upper end surface of the shell 3, and at least three taper trimming units 2 are provided on the platform 1. A step 4 for limiting is provided on the side of the shell 3 and below the platform 1, and a size measuring groove 5 is also provided on the side of the shell 3. The function of the step 4 is to limit the position, which is used for limiting the length of each taper trimming; the size measuring groove 5 is used for length inspection of the gutta-percha tip after each hot gutta-percha cutting and forming.

[0018] The platform 1 is provided with a hexagonal hole 6 for placing the taper trimming unit 2, and a platform is provided at the lower end of the hexagonal hole 6, and the taper trimmer 2 is placed on the hexagonal hole 6. The hexagonal hole 6 is a structure that matches the shape and size of the hexagonal cap 7 on the taper trimming unit 2, and the taper trimming unit 2 can be placed in the hexagonal hole 6 and supported by the platform at the lower end. The hexagonal hole can also realize the function of preventing the taper trimming unit from rotating when the gutta-percha tip is cut.

[0019] like Figure 3 As shown, the figure includes a taper trimming unit 2 including a hexagonal cap 7 and two taper cutting columns 9. The two taper cutting columns 9 are connected to the lower end of the hexagonal cap 7, and the inner side of the taper cutting column 9 is a taper cutting blade 8.

[0020] The tapered cutting column 9 is adhered to the lower end of the hexagonal cap 7 by AB glue.

[0021] The material of the tapered cutting column 9 is martensitic stainless steel, and a tapered hole is arranged therein. The tapered cutting column has a circumferential groove on the circumference and a sharp cutting edge in the clockwise direction, which is used for cutting the excess material of the gutta-percha tip and for removing the cutting waste.

[0022] The taper trimming units 2 correspond to a group of trimming tapers respectively. Each taper trimming unit 2 corresponds to a trimming taper, which is selected according to actual needs.

[0023] Working principle: according to the size of the formed root canal file, select the corresponding gutta-percha taper trimmer and a hot gutta-percha with a larger taper and diameter, insert the hot gutta-percha tip to be trimmed into the taper trimming unit 2, and slowly rotate it clockwise while applying downward force until the bottom of the gutta-percha tip reaches the step plane; take out the hot gutta-percha tip and put it into the dimension measuring groove on the outer surface of the taper trimmer shell to measure its length and the radial dimension of the corresponding position; repeat the above steps, put the hot gutta-percha tip into other taper trimming units in turn, and finally take out the hot gutta-percha tip that has completed taper trimming, and inspect its overall size.

[0024] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
