[0043] According to the pipe connection machine 1 provided by the present invention, Figure 1 As shown, the two groups of clamping assemblies 11 each include a first clamping unit 111 and a second clamping unit 112 spaced apart along the second direction; the first clamping unit 111 is provided with a plurality of first clamping grooves 1111 spaced apart along the second direction, and the second clamping unit 112 is provided with a plurality of second clamping grooves 1121 spaced apart along the second direction, the first clamping grooves 1111 are used to clamp a plurality of connecting pipes within the first pipe diameter range, and the second clamping grooves 1121 are used to clamp a plurality of connecting pipes within the second pipe diameter range.

[0044] Specifically, in this embodiment, the tube diameter of the first clamping groove 1111 is larger than the tube diameter of the second clamping groove 1121. The user can place the larger diameter connecting pipe in the first clamping groove 1111 of the larger diameter for clamping and fixing, and place the smaller diameter connecting pipe in the second clamping groove 1121 of the smaller diameter for clamping and fixing. After fixing, use the cutting wire 12 to cut, and then use the baking device 13 to heat the connecting pipe, so as to complete the connecting of blood bag pipes with different diameters at the same time, improve the efficiency of connecting, and save costs.

[0046] It should be noted that, according to different requirements, the first clamping groove 1111 and the second clamping groove 1121 can be provided in different numbers, and there is no limitation to this.
