It will be appreciated that the cross-sectional diameter of the part of the piercing member 120 that penetrates into the through-channel 111 is smaller than the inner diameter of the through-channel 111 in order to avoid that the part of the piercing member 120 that is inside the through-channel 111 blocks the through-channel 111 when the piercing member 120 is moved towards the sealed end of the through-channel 111 and out of the through-channel 111.
One end of the through channel 111 is sealed by the sealing member 140, that is, one end of the through channel 111 sealed by the sealing member 140 achieves the sealing effect, and the puncturing member 120 penetrates into the through channel 111 and breaks the sealing member 140 toward one end of the sealing member 140, so that the through channel 111 is in a completely penetrating state.
It will be appreciated that the seal 140 is a metal sheet and the thickness of the metal sheet is in the range of: the piercing member 120 can be pierced within a thickness range by the pushing action of the power mechanism 130.
