[0006] In the above technical scheme, the connecting assembly comprises a clamping groove arranged on the fixed seat and an inverted buckle arranged on the inner side of the anti-dropping cap.

[0007] In the above technical scheme, the lower ends of the outer limiting column and the inner limiting column are riveted on the mounting seat.

[0008] In order to achieve the above purpose, the second technical scheme of the utility model is as follows: a peristaltic pump, comprising a shell, a pump core is arranged in the shell, the limiting mechanism is arranged on the pump core, the pump core comprises a pump core support, a mounting seat and a roller, the mounting seat is hinged on the pump core support, the roller is arranged on the mounting seat, the outer limiting column and the inner limiting column of the limiting mechanism are arranged on the mounting seat and located at one side of the roller.

[0009] In the above technical scheme, the catheter is clamped between the outer limiting column and the inner limiting column.

[0010] In the above technical scheme, two limiting mechanisms are arranged on the pump core, and the two limiting mechanisms are diagonally arranged.

[0011] To sum up, the technical scheme of the utility model has the beneficial effects compared with the traditional technical means: the utility model sets up the limiting mechanism on the pump core, and the catheter is clamped between the outer limiting column and the inner limiting column during use, which can on one hand cooperate with the embedded slot on the pump core and the shell to automatically install the catheter, and the installation of the catheter is more convenient, and the catheter installation efficiency can be effectively improved, and on the other hand, the catheter can be limited during the operation of the peristaltic pump, and the catheter is prevented from being thrown out.
