For example, the quick-change toilet brush described in item 6 of the scope of patent application, wherein the sleeve of the cleaning brush head is formed into a tapered shape, and the sleeve is inserted into the through sleeve of the set by the second end of the handle body The hole is located in the second section of the through hole of the assembly sleeve, and the diameter of the sleeve hole of the sleeve is smaller than the diameter of the clamping joint of the second rod section of the actuating rod, and the cylinder wall of the sleeve is A number of slit grooves are formed in the axial direction, and the slit grooves are communicated with the sleeve hole of the sleeve, so that the sleeve hole of the sleeve is formed with tension and elasticity. For example, the quick-change toilet brush described in item 6 of the scope of patent application, wherein the through hole of the assembly sleeve is such that the orifice located at the second section is formed as a polygonal orifice, and the cleaning brush head has the sleeve A polygonal embedding part is formed at the connection between the barrel and the cleaning brush head, and the polygonal embedding part of the sleeve is fitted and positioned correspondingly with the polygonal hole of the assembly sleeve. For example, the quick-change toilet brush described in item 1 of the scope of patent application, wherein the hole diameter of the sleeve of the cleaning brush head is smaller than the diameter of the clamping joint of the actuating rod, and the cleaning brush head has the sleeve The cylinder wall is formed with several slits along its axial direction, and the slits are communicated with the sleeve hole of the sleeve, so that the sleeve hole of the sleeve is formed with tension and elasticity.
