By moving, the length of the gripping portion 3 expands and contracts from the state shown in FIG. 4 to the states shown in FIGS. 2 and 3. The end part of the inner cylinder 33 has a circular cross-sectional shape, but the other parts of the inner cylinder have a circular cross-sectional shape, as shown in FIG. It has a shape in which a bulging surface 33a is formed on its outer periphery. On the other hand, outer cylinder 3
The distal end of the inner cylinder 33 has an inner circumferential surface having a shape corresponding to the outer circumferential surface of the inner cylinder 33, and two concave surfaces 3 are formed so that the inner diameter thereof gradually increases in the half-circumferential portion divided into two.
4a is formed on the inner circumference of the tip. Outer cylinder 3
The inner circumferential surface of No. 4 except for the tip has a normal circular cross section. Therefore, in a position where the concave surface 34a of the outer cylinder 34 and the bulging surface 33a of the inner cylinder 33 are correctly aligned, the outer cylinder 34 can slide in the axial direction (longitudinal direction) of the outer circumference of the inner cylinder 33, Outer cylinder 3 for inner cylinder 33
4 or by rotating the inner cylinder 33 relative to the outer cylinder 34, the bulging surface 33a of the cylinder 33 aligns with the concave surface 3 of the outer cylinder.

The hand-held cleaning device configured in this way is
For example, it is used when cleaning a bathtub, and a cleaner holds the grip 3 in one hand and cleans by rotating and pressing the rotating brush 2 against a cleaning surface that has been sprayed with detergent, water, or the like. At this time, the grip part 3 can be rotated vertically within a range of about 180 degrees with respect to the main body case 1, and the angle of the rotating brush 2 with respect to the grip part 3 can be changed. It is possible to properly apply the rotating brush 2 to surfaces in various directions and perform good cleaning. In addition, since there is a long grip part 3 having an inner cylinder 33 and an outer cylinder 34, when cleaning the bottom of a deep bathtub, etc., by holding this grip part 3, the rotating brush 2 can be easily pressed against the cleaning surface. You can easily clean even deep places. If either the inner cylinder 33 or the outer cylinder 34 of the gripping part 3 is rotated relatively to the left, the pressing action of the bulging surface 33a of the inner cylinder 33 at the connecting part 1 will be reduced and the tightened state will be released. The inner cylinder 33 has a length that makes it easy to clean the gripping part 3 so that it can be slid.
and the fitting length of the outer cylinder 34, and then the inner cylinder 3
3 or the outer cylinder 34 relatively to the right a little to restore the original tightened state, the length of the gripping part 3 can be easily changed depending on the location to be cleaned. In addition, since it incorporates a rechargeable dry cell battery that is small enough to be stored in the terminal case, the cleaning device is lightweight and can be cleaned relatively easily even when held with one hand.

<Effects of the Invention> As explained above, according to the cleaning device of the present invention, the cylindrical grip part is rotatably supported on the main body case, and the terminal is removably fitted to the end of the grip part. Since the case has a built-in rechargeable battery and a charging circuit, the cleaning device can be made lighter compared to a case where a large non-rechargeable battery is built in to operate for a certain amount of time, making it easier for cleaners to operate. can be easily cleaned by holding the grip with one hand. In addition, since a rechargeable battery and charging circuit are installed inside the terminal case that is removably fitted to the grip, the battery and charging circuit can be inspected and repaired easily and quickly, and the cleaning device can be prevented from malfunctioning. This can prevent the occurrence and extend the lifespan. Furthermore, since the grip rotates relative to the main body case, the rotating brush can be easily pressed against the cleaning surface just by holding the grip, even in deep places such as bathtubs or in corners where the angle of the cleaning surface changes significantly. Cleaning can be done.
