Therefore, when the puncture body 1 and the steel sleeve 2 are assembled, the steel sleeve 2 only needs to be slid along the puncture section 11. Because the outer diameter of the barb 20 is greater than the outer diameter of the channel passing groove 101, the barb 20 can push the installation part 100 open in the process that the barb 20 passes through the channel passing groove 101, the installation part 100 is forced to elastically deform towards the direction away from the puncture part 11, and the installation part 100 resets due to the elastic action of the barb 20 until the barb 20 is clamped into the installation groove 102, so that the steel sleeve 2 can be stably fixed under the condition of no external interference, and the barb 20 is prevented from being separated from the installation part 100.

Further, the thickness of the steel jacket 2 is 0.2 to 0.5 mm for cost saving, and preferably, the thickness of the steel jacket 2 is 0.3 mm.

Furthermore, after the conventional puncture outfit is inserted into an infusion bottle, the puncture outfit is easy to loosen and fall off from the infusion bottle or an infusion bag along with the time or the movement of a patient, so that the annular mounting boss 21 is arranged on the outer side of the steel sleeve 2 in the embodiment. The steel sleeve 2 penetrates the bottle stopper of the bottle mouth of the infusion bottle a and then continues to penetrate until the annular boss 21 penetrates the bottle mouth of the infusion bottle a, so that the rubber bottle stopper of the bottle mouth of the infusion bottle a is clamped between the annular boss 21 and the push plate 10, and the annular boss 21 can prevent the penetrating part 11 from sliding out of the bottle mouth of the infusion bottle a when the puncture device is subjected to small external force.

Furthermore, in order to facilitate the annular boss 21 to pass through or exit from the bottle opening of the infusion bottle a, in the embodiment, the annular boss 21 is arranged in a circular arc shape, and the contact surface of the annular boss 21 and the bottle stopper of the bottle opening of the infusion bottle a is a circular arc surface, so that the annular boss is more convenient to pull out and insert, the steel sleeve 2 is prevented from being difficult to pull out after being inserted into the bottle opening of the infusion bottle a, and the difficulty in processing medical wastes is increased.
