Description

[Technical Field]

[0001] This utility model relates to the technical field of household flat mops, and more particularly to a flat mop that can be unlocked and cloth clamped with one hand. [Background technology]

[0002] A flat mop is a commonly used household cleaning tool that typically includes a mop rod and a mop head. The mop head has extendable cloth clamping claws on both sides, which are used to grip the cleaning cloth. The upper end of the mop rod is the gripping end, and users typically hold the gripping end of the mop rod to perform cleaning operations.

[0003] Currently, there are several flat mops on the market that are driven by twist rods, which transmit power to the cloth clamping claws by axial displacement of the inner mop rod and the outer mop rod, thereby moving and opening the cloth clamping claws. Therefore, these flat mops require the operator to hold the inner mop rod and the outer mop rod with both hands, respectively, move the inner mop rod upward relative to the outer mop rod, and rotate the twist rod to drive the cloth clamping claws outward. Therefore, it is possible to design a flat mop that allows an operator to control the opening of the cloth clamping claws simply by operating the gripping end of the mop rod with one hand, and after the cloth clamping claws are opened, by pushing down the entire mop rod and the mop head with one hand to grip the cleaning cloth onto the mop head.
