During the preparation process of the infusion set, the three-way tube needs to be assembled with the short tube and the long tube of the infusion set respectively. The three-way tube and the short tube of the infusion set are assembled to form a three-way short tube assembly. Before the three-way short tube assembly is made, the short tube and the three-way tube of the infusion set need to be processed separately, and then the short tube and the three-way tube of the infusion set, which have been coated with glue at one end, are plugged in and glued together through the assembly equipment of the three-way tube and the short tube of the infusion set. The existing three-way tube and infusion short tube assembly equipment still has many shortcomings in actual use, such as: (1) the device for clamping the three-way tube during the assembly process has a single function, a large structural design, a complicated operation process, and poor operation accuracy, which affects the assembly efficiency of the three-way tube and the infusion short tube; (2) the placement device of the infusion short tube has a complex structural design, is inconvenient to operate, and the short tube is not clamped in an stable position.
