[0020] The interior of the assembly block 6 is symmetrically provided with a card slot 8, one end of the connecting tube 2 is connected to a connector 7, and the outer side of the connector 7 is symmetrically connected to an elastic clip 9, and the connecting head 7 is connected to the card slot 8 by the elastic clip 9, and the shape of the elastic clip 9 is set to a trapezoidal structure, and the material of the elastic clip 9 is set to elastic plastic, and the outer side of the elastic clip 9 passes through the interior of the card slot 8, and the end of the needle tube 4 extending out of the connecting tube 2 is inserted into the assembly block 6 at the right end of the syringe 1, so that the needle tube 4 is inserted into the interior of the syringe 1 and passes through its left end. At this time, the connector 7 at the left end of the connecting tube 2 is inserted into the interior of the assembly block 6, and the assembly The inner wall of the matching block 6 first squeezes the elastic clip 9 to contract in the direction of the connecting head 7. When the positions of the elastic clip 9 and the slot 8 are parallel to each other, the elastic clip 9 uses its own elastic recovery ability to reset, so that the outer side of the elastic clip 9 passes through the interior of the slot 8 and is engaged with it, so as to connect the syringe 1 and the connecting tube 2 together. When the needle tube 4 needs to be withdrawn, the elastic clip 9 is pressed to withdraw from the interior of the slot 8. At this time, the slot 8 and the elastic clip 9 are no longer engaged with each other, and the connection between the syringe 1 and the connecting tube 2 is released. At this time, the outer wall of the connecting tube 2 can be pinched and rotated to facilitate the withdrawal of the needle tube 4 from the subcutaneous tissue, while the protein thread 5 remains under the skin.

[0021] A limit block 10 is provided at one end of the assembly block 6, and a plurality of paddles 11 are distributed in a ring shape inside the limit block 10. An arc groove is provided at one end of the paddle 11.
