[0029] See Figures 1 to 8 This utility model provides a retractable toilet brush, including a handle and a brush head 1 disposed at the bottom of the handle. The handle includes a first telescopic rod 2 and a second telescopic rod 3 fitted onto the upper end of the first telescopic rod 2. The second telescopic rod 3 can be raised and lowered along the first telescopic rod 2. A locking mechanism is installed at the top of the first telescopic rod 2. The locking mechanism can be used to lock or unlock the second telescopic rod 3. When locked, the second telescopic rod 3 is fixed relative to the first telescopic rod 2. The locking mechanism includes a rotating platform 4 and an expansion ring 5 fitted onto the rotating platform 4. When the first telescopic rod 2 and the second telescopic rod 3 rotate relative to each other in a first direction, the rotating platform 4 drives the expansion ring 5 to expand or rotate to expand. At this time, the expansion ring 5 can lock the external second telescopic rod 3, and the second telescopic rod 3 cannot extend or retract relative to the first telescopic rod 2. When the first telescopic rod 2 and the second telescopic rod 3 rotate relative to each other in the opposite direction of the first direction, the rotating platform 4 drives the expansion ring 5 to shrink or rotate to shrink. At this time, the expansion ring 5 unlocks the second telescopic rod 3.

[0030] In some embodiments, such as Figures 3-5As shown, the expansion ring 5 is hollow, and a central column 10 is provided on the rotating table 4. The central column 10 is eccentrically positioned on the rotating table 4, and the expansion ring 5 is also eccentrically positioned. The expansion ring 5 is fitted onto the central column 10. During rotation, the eccentric central column 10 and the eccentric expansion ring 5 are offset from each other, causing the expansion ring 5 to expand. The side wall of the expansion ring 5 is provided with multiple teeth 9, which are interference-fitted against the inner wall of the second telescopic rod 3. The cross-sectional length of the teeth 9 decreases sequentially from the opening 6 to both sides. Therefore, the expansion ring 5 closer to the opening... The toothed part 9 fits more tightly with the inner wall of the second telescopic rod 3, which can achieve locking after expansion. An opening 6 is provided on one side of the expansion ring 5, and a blocking part 7 is provided on both sides of the opening 6. A stop block 8 is provided on the rotating table 4. The stop block 8 is used to prevent the expansion ring 5 from loosening after locking. Because they rotate eccentrically, the stop block 8 and the stop part 7 cooperate to play a supporting role. The bottom of the rotating table 4 is symmetrically provided with buckles 11, and the end of the first telescopic rod 2 is symmetrically provided with slots 12. The buckles 11 are inserted into the slots 12.

[0031] In some embodiments, such as Figures 6-8 As shown, a locking rod 13 and a clamping member 14 are installed inside the first telescopic rod 2. The locking rod 13 is positioned above the clamping member 14, and the bottom of the clamping member 14 clamps the brush head 1. Specifically, the middle of the clamping member 14 is a hinge point, and the lower end clamps the brush head 1 through a clamp 15. The top of the clamping member 14 is an arc-shaped guide portion 16, and a spring 17 is provided between the guide portions 16. The spring 17 opens the guide portion 16 at the upper end of the clamping member 14, thereby clamping the bottom clamp 15. The lower end of the locking rod 13 is a locking groove 18, which can push the guide portion 16 to retract. Therefore, when the locking rod 13 is pressed down, it can drive the guide portion 16 to retract through the locking groove 18, at which time the clamp 15 is released. Unlockable, detachable brush head 1; a return spring 19 is installed at the bottom of the locking rod 13, a stop plate 20 is provided inside the first telescopic rod 2, the return spring 19 abuts against the stop plate 20, a knob 21 is connected to the top of the locking rod 13, the knob 21 is slidably mounted on the first telescopic rod 2, pressing down the knob 21 can drive the locking rod 13 to press down to unlock the clamping member 14, after releasing, the return spring 19 will drive the locking rod 13 to reset. In this embodiment, the first telescopic rod 2 is connected to the external toilet seat 22, a first magnetic block 23 is installed on the surface of the first telescopic rod 2, and a second magnetic block 24 is installed on the toilet seat 22. The toilet brush can be fixed to the wall by the two magnetic blocks.

[0032] This utility model provides a retractable toilet brush. By rotating the second telescopic rod, the expansion ring in the internal locking mechanism can be deformed, thereby locking or unlocking the second telescopic rod. When unlocked, the second telescopic rod can be extended or retracted relative to the first telescopic rod. After locking the locking mechanism again, it can be positioned, thereby improving the applicability of the toilet brush and making it suitable for various scenarios. In addition, the brush head at the bottom of the toilet brush can be pressed and disassembled, which is convenient and quick.

[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
