[0037] Continuing, in a preferred embodiment of the utility model, referring to Figure 5 As shown in the figure, the first mounting hole 2101 is arranged as a tapered hole, the smaller-diameter end of the first mounting hole 2101 is arranged away from the receiving groove 23 in the axial direction and is communicated with the second mounting hole 2401, and the larger-diameter end of the first mounting hole 2101 is communicated with the receiving groove 23 in the axial direction. Preferably, the fixing part 24 and the needle base 2 are arranged as an integrally formed structure.

[0038] It should be noted that in the prior art, when the needle core is assembled, the tail end of the needle core is inserted and installed into the inside of the needle base 2 from the outside of the needle base 2, and glue is applied at the connection between the tip of the needle core and the needle base 2; limited by the installation direction of the needle core, in order to achieve the effect of the same height of the needle core tips, the requirement for the length consistency of the needle core is relatively high. Accordingly, the present utility model provides a first mounting hole 2101 and a second mounting hole 2401 that are in communication with each other, and changes the upper needle direction of the needle core 6 so that its tip penetrates from the accommodating groove 23 to the outside of the end portion 21. The needle base 2 and the silica gel backing plate are arranged opposite to each other. When the tips of each group of needle cores 6 abut against the silica gel backing plate, the positioning of the needle core 6 is completed, and the needle core 6 is fixed in the conical structure of the first mounting hole 2101. On the one hand, this assembly method makes the heights of the needle core tips consistent, the injection amounts at the positions of each needle core during injection are the same, and the injection effect is more uniform; on the other hand, this assembly method has lower requirements for the length error of the needle core, saves production costs; is less affected by consistency, and has a higher yield rate.

[0039] Specifically, the fixing parts 24 are arranged in an array at the end portion 21 of the needle base 2; referring to Figure 3 As shown, in some embodiments, the fixing parts 24, the needle cores 6, the first mounting holes 2101 and the second mounting holes 2401 are all provided in nine groups, and the multi-hole hydro-needle is provided as a nine-hole needle; in some embodiments, referring to Figure 6 As shown, the multi-hole hydro-needle can also be provided as a sixteen-hole needle; the number of the fixing parts 24 and the needle cores 6 can be determined according to the injection requirements, and is not limited thereto; when the fixing parts 24 are arranged in an array, a reinforcing rib 25 is also connected between the fixing parts 24.
