The driving unit 250 may be implemented as a motor that rotates in one direction or the opposite direction under the control of the control unit 230 and may drive the movable manipulator 270 according to the rotation of the motor.

The movable control unit 270 is implemented as a gear gear mechanism and receives driving force from the driving unit 250 to operate the movable locker 110 . The movable control unit 270 is rotationally fixed to the input gear 271 connected to the rotational shaft of the drive unit 250 and the intermediate gear 273 installed to be rotationally fixed to the lower portion of the input gear 271 and the lower portion of the intermediate gear 273 It may include an output gear 275 installed to be. Here, the gears may be made of a plastic material.

The input gear 271 may be composed of a worm gear. In the input gear 271, a screw-shaped worm is installed on the rotational shaft of the driving unit 250, and the gear is interlocked with the rotational shaft and installed to rotate according to the drive of the driving unit 250 to generate power can be forwarded to the side. That is, the input gear 271 may transmit rotational power of the drive unit 250 by crossing two axes that are neither crossed nor parallel. Here, the input gear 271 uses a double gear so that the upper gear is engaged with the worm and the lower gear is installed to engage with the intermediate gear 273 to receive the power of the driving unit 250 and to the intermediate gear 273 without noise. power can be transmitted. At this time, the size of the lower gear of the input gear 271 may be smaller than the size of the upper gear so that rotational interference between the input gear 271 and the intermediate gear 273 does not occur.
