Liquid spreader

A liquid spreader comprising:

• first and second upper shafts extending in a left and right direction having a predetermined interval therebetween in a front and rear direction;
• a first-side frame connected to a first side of the first upper shaft and a first side of the second upper shaft;
• a second side frame connected to a second side of the first upper shaft and a second side of the second upper shaft;
• first and second bar-shaped operation handles, wherein the first operation handle is fixed on the first side frame and the second operation handle is fixed on the second side frame;
• and
• a spray nozzle that sprays a liquid into a space between the first and second side frames;
• wherein
• the first operation handle is configured to rotate about a longitudinal axis of the first side frame, the longitudinal axis of the first side frame extending in the front and rear direction, whereby a rotational angle of the first side frame about the longitudinal axis of the first side frame is adjusted, and the second operation handle is configured to rotate about a longitudinal axis of the second side frame, the longitudinal axis of the second side frame extending in the front and rear direction, whereby a rotational angle of the second side frame about the longitudinal axis of the second side frame is adjusted, and
• a distance between the first operation handle and the second operation handle changes along with at least one of (i) a change of the rotational angle of the first side frame and (ii) a change of the rotational angle of the second side frame.
