[0041] The ball 4 is spherical, and its diameter is smaller than the diameter of the liquid channel 101 of the syringe 1, that is, smaller than the inner diameter of the syringe 1, and its diameter is larger than the inner diameter of the tapered small end of the liquid outlet 12 of the syringe 1.

[0042] The ball 4 is arranged in the liquid passage 101 of the syringe 1, and is located at the liquid outlet end (upper end) of the syringe 1. The spring 3 is arranged in the liquid passage 101 of the syringe 1, and the spring 3 is in a compressed state. The bottom end of the spring 3 abuts against the support plate 21 of the tray 2, and the top end of the spring 3 abuts against the bottom of the ball 4. The spring 3 pushes the ball 4 to move upward, so that the ball 4 abuts against the conical inner wall of the liquid outlet 12 of the syringe 1, so that the ball 4 closes the liquid outlet 12 of the syringe 1, and the top end of the ball 4 extends out of the top surface of the syringe 1; when the ball 4 is pressed downward, the ball 4 is away from the liquid outlet 12 of the syringe 1, and the liquid outlet 12 of the syringe 1 is in an open state, and the liquid can flow out of the liquid passage 101 of the syringe 1.
