Pin wheel and terminal material strip conveying device

A terminal material strip conveying device, comprising:

• a pin wheel including:
• an outer wheel having an inner cavity extending through the outer wheel along an axial direction and a plurality of radial through-holes communicated with the inner cavity, the radial through-holes are evenly spaced in a circumferential direction of the outer wheel and each have an outer opening on an outer peripheral surface of the outer wheel, the outer wheel includes a first outer wheel part and a second outer wheel part that are coaxially connected, a diameter of the first outer wheel part is greater than a diameter of the second outer wheel part, the inner cavity runs axially through the first outer wheel part and the second outer wheel part, the radial through-holes are formed in the first outer wheel part;
• an inner wheel assembled in the inner cavity to rotate together with the outer wheel, a plurality of grooves are formed on an outer peripheral surface of the inner wheel;
• and
• a plurality of pins respectively and movably installed in the radial through-holes, a first end of each of the pins extends out of the outer opening of one of the radial through-holes to engage with a positioning hole of a terminal material strip and drive the terminal material strip forward when the pin wheel is rotated, the grooves of the inner wheel respectively correspond to a second end of each of the pins to allow the second ends of the pins to each enter one of the grooves, wherein
• the inner wheel of the pin wheel is adapted to be connected to a driving device for driving the outer wheel and inner wheel of the pin wheel to rotate together.
