[0021] See Figures 1 to 7As shown, a clamping structure of a toilet brush head, which comprises a brush rod 1, a transmission mechanism and a clamping mechanism are installed in the brush rod 1, the transmission mechanism comprises a guide rod 2, the top of the guide rod 2 is matched with a button 3 installed on the brush rod 1, the bottom of the guide rod 2 is connected with a control rod 5 through a connecting frame 4, the inside of the brush rod 1 is provided with a limiting plate 6 passing through the connecting frame 4, the two ends of a reset spring 7 are respectively abutted with the top of the connecting frame 4 and the limiting plate 6, the reset spring 7 can reset the guide rod 2 after moving; the control rod 5 is provided with an upper limiting sheet 8 and a lower limiting sheet 9, the clamping mechanism comprises brush head clamps 10 arranged on both sides of the control rod 5, which are generally symmetrically arranged, the outside of the brush head clamp 10 is provided with a rotating shaft slot in the middle, the inner wall of the brush rod 1 is provided with a boss 19, the boss 19 is provided with a rotating shaft 20 matched with the rotating shaft slot, so that the brush head clamp 10 can rotate around the rotating shaft 20, when the control rod 5 moves upward, the upper part of the brush head clamp 10 is opened by the upper limiting sheet 8, so that the lower part of the brush head clamp 10 is inwardly closed to clamp the brush head 11; when the control rod 5 moves downward, the lower part of the brush head clamp 10 is pushed open outwardly by the lower limiting sheet 9, at this time, the originally clamped brush head can be released or the new brush head is prepared to be clamped.

[0022] The brush head clamp 10 is W-shaped, two brush head clamps 10 form two accommodation areas between them, which are used to accommodate the upper limiting sheet 8 and the lower limiting sheet 9 respectively; when the control rod 5 moves upward, the upper limiting sheet 8 contacts the upper part of the brush head clamp 10, the lower limiting sheet 9 is retracted into the lower accommodation area and does not contact the brush head clamp 10, which can make the lower part of the brush head clamp 10 inwardly close; when the control rod 5 moves downward, the upper limiting sheet 8 is retracted into the upper accommodation area and does not contact the brush head clamp 10, while the lower limiting sheet 9 contacts the brush head clamp 10 and pushes it outwardly, so that the lower part of the brush head clamp 10 is opened, the brush head 11 can be released or used to prepare to clamp the brush head 11, the lower part of the brush head clamp 10 is provided with a brush head clamp hole 12, which ensures that the brush head 11 can be clamped smoothly.

[0023] The sidewall of the brush rod 1 is provided with a button mounting hole, the button 3 is inserted and mounted in the button mounting hole, the top of the guide rod 2 is matched with an inclined surface, when the button 3 is pressed, the guide rod 2 is pushed under the action of the inclined surface, when the button 3 is released, the guide rod 2 can reset under the action of the reset spring 7. The brush rod 1 at the button mounting hole horizontally extends a limiting seat 13, which can limit the movement direction of the button 3, so that it can only move along the radial direction of the brush rod 1, the button 3 around extends a button limiting sheet 14, which can prevent the button 3 from being popped out of the brush rod 1 when it resets. 21 in the figure is a button limiting sheet, which is used to limit the pressing depth of the button 3.

[0024] The inside of the brush rod 1 is further provided with a guide ring 15 matched with the guide rod 2, so that the guide rod 2 can smoothly realize the guidance.

[0025] The brush rod 1 is formed by inserting the upper rod 16 and the lower rod, the lower rod is formed by splicing the front half rod 17 and the rear half rod 18, and the button 3 is installed on the lower rod.

[0026] The working principle is as follows: in the normal use state, the button 3 is in the protruding state, the guide rod 2 is supported by the reset spring 7, the control rod 5 is in the upward state, the upper part of the brush head clamp 10 is opened and the lower part is folded by the upper limiting sheet 8, the brush head 11 is clamped and fixed, at this time, the brush head 11 can be used for cleaning operation; when the brush head 11 needs to be replaced, only the button 3 needs to be pressed, the guide rod 2 is pushed to move downward, the control rod 5 also moves downward, the lower part of the brush head clamp 10 is opened outward by the lower limiting sheet 9, the brush head 11 originally clamped is no longer in the clamping state, the brush head 11 automatically falls off under the action of its own gravity or the brush head 11 is supported on the ground, the brush rod 1 is lifted upward to realize the separation from the brush head 11, the new brush head 11 is moved to the position, the button 3 is pressed again after the position is aligned, the lower part of the brush head clamp 10 is opened again, then the top of the brush head 11 is inserted into the brush rod 1, and the button 3 is released, under the action of the reset spring, the guide rod 2 is reset, the control rod 5 also moves upward, the upper part of the brush head clamp 10 is opened and the lower part is folded by the upper limiting sheet 8, the brush head 11 is clamped and fixed, and the replacement operation is completed.
