Here's a breakdown of the simple machines found in each item on your list:

| Item | Lever | Inclined Plane | Pulley | Screw | Wedge | Wheel/Axle |
|-------------------------|-------|----------------|--------|-------|-------|-------------|
| Wheelbarrow | ✔ | | | | | ✔ |
| Stapler | ✔ | | | | | |
| Fishing Rod | ✔ | | | | | ✔ |
| Desktop tape dispenser | | | | ✔ | | |
| Pizza cutter | | | | | ✔ | |

### Explanations:
- **Wheelbarrow**: It uses a wheel/axle for movement and a lever to lift and support the load.
- **Stapler**: The mechanism acts like a lever to press down the staple.
- **Fishing Rod**: The rod acts like a lever for casting, and the reel (if applicable) serves as a wheel/axle for winding the line.
- **Desktop tape dispenser**: It uses a screw mechanism for tension in the cutting action.
- **Pizza cutter**: The circular blade acts as a wedge to cut through the pizza.
