[0037] The plurality of sets of opening plates 37 are arranged side by side, and the upper and lower two opening plates 37 of each set of opening plates 37 are respectively installed on two mounting rods 39. A spacing adjusting assembly 40 is arranged between the two ends of the two mounting rods 39. The spacing adjusting assembly 40 is a vertical guide rod. The guide rod is two rods, and the two guide rods pass through the two mounting rods 39. The two mounting rods 39 are lifted on the guide rod. A No. 6 air cylinder is installed between the guide rod and each mounting rod 39 through bolts. The mounting rod 39 moves on the guide rod by the extension and retraction of the No. 6 air cylinder.

That is, a first guide rail is fixed on the table top 1 by bolt fastening. A first sliding seat that moves on the first guide rail is clamped on the first guide rail. The first sliding seat is fixed to the bottom of the guide rod by bolt fastening. A No. 7 air cylinder is installed between the first sliding seat and the table top 1 by bolt fastening. The left and right translation of the opening plate 37 is realized by the extension and retraction of the No. 7 air cylinder.

[0038] The upper and lower two opening plates 37 of each set of opening plates 37 are mutually staggered. When the two mounting rods 39 are folded, the end of each set of opening plates 37 away from the mounting rod 39 is on the same plane. The end of the opening plate 37 close to the mounting rod 39 is an inclined section. This facilitates the extension of each set of opening plates 37 into the bag body. When the end of the two opening plates 37 extending into the bag opening is on the same plane, the width of the bag opening required for the extension of the opening plate 37 into the bag body is smaller. This facilitates the extension of the opening plate 37 into the bag body. By avoiding the situation that the opening plate 37 is lifted and extended into the bag body and the opening plate 37 is abutted on the edge of the bag body and cannot open the bag body.

[0039] Each of the opening plates 37 on the upper mounting rod 39 is divided into two, and an expansion assembly 43, i.e. a finger cylinder, is arranged between the two opening plates 37.

During work, the mounting rods 39 are closed, so that the opening plates 37 are located on the same horizontal plane. The bag is opened by the opening assembly 35. One end of the opening plate 37 is inserted into the opened bag opening by the first translation assembly 41. Then, the two mounting rods 39 are separated, so that the bag is opened. Then, the docking cylinder 25 is inserted into the bag, and the docking cylinder 25 leaves the blood collection needle in the bag. Then, the docking cylinder 25 exits the bag. The mounting rods 39 are closed, and finally the expansion assembly is opened, so that the opening plates 37 move to the two sides. In this way, the bag opening is closed, and finally the second circulating conveying assembly 42 clamps the bag. The mounting rod 39 moves to the left, and the opening rod exits the bag.
