[0017] Compared with the prior art, the advantages of the present invention are:

[0018] 1. The utility model provides an adjusting component, and by rotating the first fixing nut outward, the first fixing nut drives the movable plate to move outward through the connecting rod, and the movable plate moves outward and drives the support plate to rotate inward through the first rotation, so that the support plate drives the fixed plate and the brush to move inward, thereby reducing the spacing between the fixed plates and allowing the brush to pass through the bottle mouth. After the brush passes through the bottle mouth, the first fixing nut is rotated inward to move the movable plate inward, and the inward movement of the movable plate drives the first rotating shaft to move outward. The first rotation drives the support plate to move outward, so that the support plate drives the brush to move outward until the outer end of the brush contacts the inner wall of the bottle body, and the brush can be used to clean the inside of the bottle body.

[0019] 2. Based on beneficial effect 1, by setting a protective component, by placing the cover plate at the bottle mouth position, and making the sealing gasket contact the bottle mouth position, and then by moving the movable column inward, the movable column drives the clamping block to move inward. When the clamping block clamps the bottle mouth position, the cover plate can be fixed, so that the cleaning agent inside the bottle body will not flow out, avoiding the operator from contacting the cleaning agent, and preventing the chemicals in the cleaning agent from contacting the operator, thereby increasing the safety of the operator.
