Cloth-Clamping Flat Mop

Abstract

Provided is a cloth-clamping flat mop, including a mop rod, a mop head, and a driving mechanism. A bottom of the mop head is a wiping surface, cloth-clamping mechanisms are movably mounted on both sides of the mop head, and the driving mechanism drives the cloth-clamping mechanisms to move outward or inward; each of the cloth-clamping mechanisms includes a cloth-clamping claw and a supporting arm, and guide plates are arranged on a back side at two sides of the wiping surface; in an opened state, each of the cloth-clamping mechanisms moves outward, the cloth-clamping claw is opened outward and downward along the guide plates, and the cloth-clamping claw is lower than the wiping surface; and when cloth is clamped, the cloth-clamping claw drives the wiping cloth and retracts inward along the guide plates to clamp the cloth and reset.
