The shape of the bayonet is set according to the brush head. For example, when the brush head includes a spherical connector, the cross-sectional shape of the bayonet is circular.

[0057] When the clamping structure 2 is in the locking position, the bayonet is reduced and the brush head 3 can be clamped; when the clamping structure 2 is in the unlocking position, the bayonet is enlarged and the brush head 3 can be released.

[0058] In one embodiment, a sliding pin 24 is provided on both the first clamping portion 22 and the second clamping portion 22, and a sliding groove 23 corresponding to the sliding pin 24 is provided on the clamping cap 21, and the sliding groove 23 extends from one end close to the bottom end of the handle rod 1 to the other end, and the shortest distance between the projections of the two sliding grooves 23 on the plane perpendicular to the axis of the handle rod 1 is L, and L gradually increases from one end close to the bottom end of the handle rod 1 to the other end.

[0059] Since the shortest distance between the projections of the two slide grooves 23 on the plane perpendicular to the axis of the handle rod 1 is L, and L gradually increases from one end close to the bottom end of the handle rod 1 to the other end, when the clamping structure 2 switches from the unlocking position to the locking position, the first clamping portion 22 and the second clamping portion 22 move toward the clamping cap 21, and the shortest distance between the sliding pins 24 of the first clamping portion 22 and the second clamping portion 22 gradually decreases under the drive of the slide groove 23, and the bayonet formed between the first clamping portion 22 and the second clamping portion 22 is reduced, so that the brush head 3 can be clamped; when the clamping structure 2 switches from the locking position to the unlocking position, the first clamping portion 22 and the second clamping portion 22 move back to the clamping cap 21, and the shortest distance between the sliding pins 24 of the first clamping portion 22 and the second clamping portion 22 gradually increases under the drive of the slide groove 23, and the bayonet formed between the first clamping portion 22 and the second clamping portion 22 is increased, so that the brush head 3 can be released.

[0060] In one embodiment, two slide pins 24 are disposed on each of the first clamping portion 22 and the second clamping portion 22 . The two slide pins 24 are disposed on opposite sides of the clamping portion 22 , respectively. The clamping cap 21 is provided with slide grooves 23 corresponding to the slide pins 24 one by one.

[0061] Two sliding pins 24 are provided on each of the first clamping portion 22 and the second clamping portion 22, and the two sliding pins 24 are arranged opposite to each other, so that the first clamping portion 22 and the second clamping portion 22 can be subjected to more balanced force during sliding, and better guide and limit, thereby preventing the first clamping portion 22 and the second clamping portion 22 from sliding, skewing, and causing jamming.

[0062] In one embodiment, the clamping cap 21 includes a cap body 211 and a connecting tube 212; the cap body 211 is covered on the outside of the bottom end of the handle rod 1, and is provided with a clamping opening 2111, and the clamping opening 2111 is used to accommodate the brush head 3; one end of the connecting tube 212 is fixedly connected to the cap body 211, and the other end is detachably connected to the inside of the handle rod 1, and the clamping part 22 is slidably set on the connecting tube 212.

After releasing the push plate 71, the upper push rod 41 moves toward the direction close to the lower handle rod 12 under the action of the elastic reset member 5, and the movement of the push rod 4 drives the clamping part 22 to slide toward the clamping cap 21. The bayonet formed between the two clamping parts 22 gradually decreases under the cooperation of the slide groove 23 and the slide pin 24 until the clamping structure 2 reaches the locking position and is kept in the locking position by the elastic reset member 5, clamping the connecting member on the brush head 3. At this time, the toilet can be cleaned by the brush head 3. After the cleaning is completed, the push plate 71 can be pushed away from the lower handle rod 12, and then the clamping structure 2 is driven to move to the unlocking position through the connecting part 72 and the push rod 4 to release the clamping of the current brush head 3.
