A basket actuator comprising:
- a base comprising a base body and a base guide installed in the base body;
- a slider comprising a slider body configured to slide along the base guide, and a first slider arm and a second slider arm formed to protrude from the slider body and facing each other;
- a roller comprising a roller body rotatably disposed between the first slider arm and the second slider arm and a plurality of roller blades formed to protrude outwardly from the roller body;
- a wire guide connected to a front end portion of the base body;
- a wire disposed inside the wire guide and having a first end fixed to the roller;
- and
- a basket connected to a second end of the wire,
- wherein the second slider arm is located rearward in comparison to the first slider arm, and
- the base further comprises a base locking part configured to rotate the roller by interfering with one of the plurality of roller blades while the slider slides backward.
A basket actuator comprising:
- a base comprising a base body and a base guide installed in the base body;
