[0018] Figures 1 to 3 As shown in the exploded view of the utility model, a sprocket-shaped replaceable brush head toilet brush clamping structure comprises a brush rod 1, the brush rod is spliced by a front half rod 14 and a rear half rod 15, a movable guide rod 2 is arranged in the brush rod 1, a button 3 for controlling the movement of the guide rod 2 is arranged on the brush rod 1, a long slot 11 is formed on the brush rod 1, a connecting block 31 on the back of the button 3 passes through the long slot 11 and is fixedly connected with the guide rod 2, and the guide rod 2 is moved by rotating the button 3. A guide ring 12 matched with the guide rod 2 is mounted in the brush rod 1, so that the guide rod 2 can stably move and will not shake.
[0019] A brush head mounting hole 4 is formed in the bottom of the brush rod 1, a spring mounting frame 21 is arranged on the guide rod 2, a limiting plate 13 is arranged in the brush rod 1 and passes through the spring mounting frame 21, and the two ends of a reset spring 5 are respectively abutted against the top of the spring mounting frame 21 and the limiting plate 13; when the button 3 is rotated downward, the reset spring 5 is compressed, the guide rod 2 moves downward, and after the button 3 is released, the reset spring 5 pushes the guide rod 2 to reset.
[0020] The bottom of the guide rod 2 is provided with an annular tooth groove 22, and two brush head clamps 6 are arranged on the two sides of the bottom of the guide rod 2; the brush head clamp 6 comprises a rotating column body 61 and a brush head clamping part 62, the two ends of the rotating column body 61 are rotatably connected with the inner wall of the brush rod 1, specifically, the two ends of the rotating column body 61 are provided with bosses 63, the inner wall of the brush rod 1 is provided with insertion grooves 16 matched with the bosses 63, so that the brush head clamp 6 can rotate. An arc-shaped tooth surface 64 engaged with the annular tooth groove 22 is arranged on the surface of the rotating column body 61.
[0021] See Figure 4 and Figure 5As shown, without pressing the button 3, the reset spring 5 is in a natural state, and the two brush head clamps 7 are in a closed state. At this time, the brush head clamping part 62 clamps the brush head 7. The top of the guide rod 2 is provided with a limiting block 23, the outer diameter of which is greater than the inner diameter of the hole of the guide ring 12, thereby playing a limiting role.
[0022] See Figure 6 and Figure 7 As shown, by pressing the button 3 downward, the reset spring 5 is compressed, the guide rod 2 moves downward, the annular tooth groove 22 on the guide rod 2 also moves downward, drives the two brush head clamps 6 to rotate, and opens outward, so that the originally clamped brush head can be released or a new brush head is prepared to be clamped. After the button 3 is released, under the action of the reset spring 5, the two brush head clamps 6 are closed again.
