Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-3 As shown, a multi-adjustable brush includes a brush head assembly 1, a handle assembly 2, and a rotatable connecting component 3. One end of the connecting component 3 is connected to the handle assembly 2, and the other end is connected to the brush head assembly 1. The brush head assembly 1 can be rotated to one end of the handle assembly 2 via the connecting component 3. The user holds the handle assembly 2 and uses the brush head assembly 1 at the end to clean stains. The ability of the brush head assembly 2 to rotate facilitates cleaning at different angles.

[0022] A movable locking block 4 is provided on one side of the connecting component 3. The locking block passes through the connecting component 3 and is partially exposed on one side of the connecting component 3. It is unlocked by manually pressing the locking block 4. The connecting component 3 has a locked state and an unlocked state: the normal state is the locked state, where the locking block 4 locks the connecting component 3, restricting the rotation of the connecting component 3 and preventing the brush head assembly 1 from rotating during brushing, thus avoiding a poor user experience; in the unlocked state, when the locking block 4 is manually pressed, the locking block 4 moves inward laterally, releasing the locking state between the locking block 4 and the connecting component 3, allowing the connecting component 3 to rotate freely. After releasing the locking block 4, the return spring force resets the locking block 4 and re-locks the connecting component 3. Users can adjust the setting to a suitable level according to their cleaning needs in different scenarios, making cleaning more convenient and effortless. The adjustment method is also relatively simple, satisfying the user's convenience.

[0023] The connecting component 3 includes a connecting block 5 and a rotating block 6 mounted on the connecting block 5. The connecting block 5 is used to connect to the handle assembly 2, and the rotating block 6 is connected to the brush head assembly 1 to drive the brush head assembly 1 to rotate. The locking block 4 passes through the connecting block 5 and the rotating block 6 in sequence and protrudes from one side of the connecting block 5.

[0029] The housing 15 has a fixing groove 17, and the rotating block 6 has a fixing block 18 that inserts into the fixing groove 17. The fixing block 18 and the fixing groove 17 are matched in contour, which can achieve the effect of lateral limiting. A fixing plate 19 is provided inside the housing 15 to abut against the housing 15. The housing 15 and the rotating block 16 are fixed by screws passing through the fixing plate 19 and the fixing block 18. The housing 15 can be removed by unscrewing the brush and removing the fixing plate 19 for easy replacement.

[0030] The handle assembly 2 includes an upper handle 20 and a lower handle 21 that interlock with each other, with a connecting end 7 fastened between the upper handle 20 and the lower handle 21. The connecting end 7 has a first positioning groove 22, and a protruding first positioning post 23 inside the lower handle 21 is fastened into the first positioning groove 22, serving to fix the connecting assembly 3. The first positioning post 23 has a second positioning groove 24, and a second positioning post 25 inside the upper handle 20 is fastened into the second positioning groove 24, further increasing the connection strength between the connecting assembly 3 and the handle assembly 2, making it less prone to detachment.

[0031] The handle assembly 2 is provided with a hanging ring 26 at its end for hanging and convenient storage.
