[0037] A sliding groove 4 is formed in each pressure seat 1, the sliding direction of the sliding groove 4 is perpendicular to the arrangement direction of the positioning tube 10, a sliding block 5 is slidingly connected in each sliding groove 4, the outer wall of the positioning tube 10 close to the positioning tube 10 end of the two pressure seats 1 is provided with a slot 22 arranged horizontally with the positioning tube 10, a pressing plate 6 is inserted and placed in the two slots 22, the two ends of the pressing plate 6 penetrate the slot 22 and are connected with the outer wall of the sliding block 5, when the needle body 11 abuts against the positioning tube 10, the bottom surface of the pressing plate 6 abuts against the top end of the needle body 11.

[0038] In specific implementation, the sliding groove 4 of the pressing seat 1 is provided with a limiting groove limiting the sliding of the sliding block 5, the outer wall of the sliding block 5 near the end of the positioning tube 10 is connected with a pressing block arranged on the surface of the insertion groove 22, the outer wall of the two ends of the pressing plate 6 is slidingly connected to the two sides of the inner wall of the insertion groove 22, and the height of the two ends of the pressing plate 6 is consistent with the depth of the insertion groove 22.

[0039] In specific implementation, the outer wall of the end of the positioning tube 10 away from the base 21 is the glue filling cavity 9 with the inner wall of the outer shell 8, and the bottom surface of the pressing plate 6 is provided with a stepped avoiding groove 16 avoiding the top end of the outer shell 8.

[0040] In specific implementation, in order to ensure the connection stability of the base 21 and the outer shell 8, the base 21 and the outer shell 8 are first bonded and solidified, then the contact end face is pressed by the pressing plate 6 after the insertion of the twist needle, and the bottom glue is completely solidified at one time.
