Further, the storage cavity is arranged on one side of the inclined surface of the trapezoidal cavity, and the storage cavity is close to one end of the trapezoidal cavity with a small opening.

Further, the upper end of the storage cavity is provided with an anti-skid ring.

Furthermore, a guide ring which is convenient for the needle to enter is arranged between the anti-slip ring and the storage cavity.

Furthermore, the guide ring is horn-shaped, and the large end of the opening of the guide ring faces the anti-skid ring.

Further, the guide ring is made of a hard material.

Compared with the prior art, the utility model has the following beneficial effects:

according to the utility model, the needle head is stored in the storage cavity, so that the phenomenon that the needle head is exposed outside to prick and damage a bag to cause residual liquid medicine in the bag to drip is avoided; simultaneously, the storage cavity is arranged at one end with a small opening close to the trapezoidal cavity, so that when the pressure stopping disc slides upwards, the pressure stopping disc can compress the needle head, and the needle head is prevented from slipping.
