[0020] The technical solution of this utility model will be further described below with reference to the accompanying drawings, but it is not limited thereto. Any modifications or equivalent substitutions to the technical solution of this utility model that do not depart from the spirit and scope of the technical solution of this utility model shall be covered within the protection scope of this utility model.
[0021] like Figures 1-5The utility model provides a simple needle threading device, which is composed of a base 12, a support 11 and a fixing seat 10. The support 11 is vertically fixed at the middle position of the base 12. The fixing seat 10 is fixedly installed at the top end of the support 11. A through tapered hole 7 is formed in the fixing seat 10 for threading the needle tube 4 from right to left. The fixing seat 10 includes a tapered column 8 and a fixing block 9. The fixing block 9 is located at the top end of the support 11 and is fixedly connected with the support 11. The width of the fixing block 9 is slightly larger than that of the support 11, so as to facilitate the threading or taking out of the needle tube 4. The tapered column 8 is located at the left side of the fixing block 9 and is integrally formed with the fixing block 9. The tapered column 8 is used for cooperating with the tapered hole 3 in the puncture needle seat to fix the puncture needle seat on the fixing seat 10. When threading the needle tube 4, the needle tube 4 is inserted into the tapered hole 7 from the entrance, and then the needle tube 4 can be accurately threaded into the puncture needle tube 1.
[0022] Preferably, a long slot 6 is formed in the fixing seat 10. The long slot 6 is through along the length direction and upward, so as to facilitate the taking out of the needle tube 4 from the fixing seat 10 along the up-down direction.
[0023] Preferably, the tapered column 8 is adapted to the tapered hole 3 in the puncture needle seat. The length of the tapered column 8 is greater than that of the tapered hole 3 in the puncture needle seat. The small end diameter of the tapered column 8 is smaller than that of the tapered hole 3 in the puncture needle seat. The large end diameter of the tapered column 8 is greater than that of the tapered hole 3 in the puncture needle seat, so as to ensure the coaxiality when the tapered column 8 cooperates with the tapered hole 3 in the puncture needle seat.
[0024] Preferably, the small end diameter of the tapered hole 7 is 0.3-0.5 mm greater than the diameter of the needle tube 4, so as to facilitate the smooth threading of the needle tube 4 into the puncture needle tube 1 from the tapered hole 7. The width of the long slot 6 is also 0.3-0.5 mm greater than the diameter of the needle tube 4, so as to facilitate the smooth taking out of the needle tube 4 from the fixing seat 10 along the up-down direction and ensure the effective fixing of the position of the needle tube 4.
[0025] In use, the tapered hole 3 in the puncture needle seat is connected with the tapered column 8 through interference fit to fix the puncture needle seat. Then, the needle tube 4 is threaded into the puncture needle tube 1 from the right side of the large end of the tapered hole 7. The tapered structure of the needle tube 4 can accurately thread the needle tube 4 into the puncture needle tube 1, so as to ensure the accuracy of the threading of the needle tube 4 and improve the production efficiency.
