The end of 10 is the first nearly syringe end 410, and the first bar-shaped trough 41 is provided with a first elastic limit portion 42,
The first restricted room 43 is formed between first nearly syringe end 410 and the free end in the first elastic limit portion 42,
When the first lobe 21 moves to the first restricted room 43 along the first bar-shaped trough 41, the first elastic limit
Portion 42 limits the first lobe 21 and moves towards the fixing end in the first elastic limit portion 42.
The outer cover of the first sleeve 40 is provided with the second sleeve 50, and the outer wall of the first sleeve 40 is provided with one
Two lobe 44, the second sleeve 50 is provided with the second bar-shaped trough 51, and the second lobe 44 is slidedly arranged on second
Bar-shaped trough 51；Second bar-shaped trough 51 is the second nearly syringe end 510 near the end of syringe 10, Article 2
Shape groove 51 is provided with a second elastic limit portion 52, the second nearly syringe end 510 and the second elastic limit portion
The second restricted room 53 is formed, when the second lobe 44 is moved along the second bar-shaped trough 51 between the free end of 52
When moving the second restricted room 53, it is elastic towards second that the second elastic limit portion 52 limits the second lobe 44
The fixing end of limiting unit 52 moves.
When the first lobe 21 moves to the first restricted room 43 and the second lobe along the first bar-shaped trough 41
44 along the second bar-shaped trough 51 move to the second restricted room 53 time, syringe needle 30 is contained within the first sleeve 40
The inner chamber formed with the second sleeve 50.
First bar-shaped trough 41 is the first remote syringe end 411 away from the end of syringe 10, the second bar-shaped trough 51
End away from syringe 10 is the second remote syringe end 511, when the first lobe 21 is along the first bar-shaped trough 41
