Specific embodiment
Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.
In conjunction with shown in Fig. 1 to Fig. 5, present embodiments provide a kind of infusion driving device, including shell 1, be articulated in it is described
The intracorporal crankshaft 2 of the chamber of shell 1, along 2 length direction of crankshaft successively parallel interval setting multiple driving pieces 3 and wear
Set on the multiple driving piece 3 for preventing the driving piece 3 from waving limit shaft 4 to two sides；The cavity wall of the shell 1 is opened
Equipped with multiple sliding slots 11, the multiple driving piece 3 is under the driving effect of the crankshaft 2 respectively along the corresponding sliding slot 11
Lower movement, the upper surface of the shell 1 offer the elongated slot exposed for the driving end 31 of the driving piece 3 along its length
12。
Specifically, the shell in the present embodiment is equipped with crankshaft using being integrally formed in the middle part of the cavity of shell, it is bent
The both ends of axis are matched by bearing with the side wall at cavity both ends；
Further, in the present embodiment, in order to guarantee that multiple driving pieces can be smooth and accurately move up and down, along driving
The direction of motion is opened up there are two for wearing the limiting slot of limit shaft piece up and down, and limiting slot is located at the two sides of crankshaft 2, and two
The end of limit shaft is fastened with the side wall at cavity both ends；
In the present embodiment, limiting slot is set as waist type groove, and the width of waist type groove and the outer diameter of limit shaft are equal, effectively with this
