Preferably, the upper surface of the connecting frame is provided with a limiting groove for the cam to be embedded in.

Through adopting above-mentioned technical scheme, the cam will be embedded into the spacing inslot when compressing tightly the connecting frame, and the cam will apply an ascending spacing power of edge horizontal direction to the connecting frame, and this has further improved the stability after connecting frame and brush hair are locked.

Preferably, the outer side wall of the connecting frame is embedded with a ball abutted against the inner side wall of the slot in a rolling manner.

Through adopting above-mentioned technical scheme, the ball can become the rolling friction of ball with the sliding friction between linking frame and the slot, has reduced the frictional resistance that the linking frame received when sliding greatly to let the linking frame insert or extract the slot smoothly, brought the facility for workman's operation.

Preferably, the connecting frame is provided with a handle for being held by a hand.

By adopting the technical scheme, the handle provides a good force application part for the worker to move the connecting frame and the bristles, and the worker can move the connecting frame and the bristles conveniently.

Preferably, the notch of the slot is flared.

Through adopting above-mentioned technical scheme, the flaring setting of slot notch department can play the effect of a direction when the splice box inserts the slot, has made things convenient for the workman to insert the splice box in the slot.

In summary, the present application includes at least one of the following beneficial technical effects:

1. the arrangement of the connecting plate, the slot, the connecting frame, the rotating shaft, the cam and the rotating mechanism realizes the detachable connection of the bristles and the cover body, and is convenient for workers to clean the bristles;

2. the arrangement of the insertion pipe and the insertion rod not only facilitates the rotation of the rotating shaft by workers, but also enables the process of rotating the rotating shaft by the workers to be more labor-saving and flexible;

3. the arrangement of the rubber sleeve improves the comfort of the hand; secondly, the probability of hand slipping is reduced, and the normal operation of the device is ensured;

4. the arrangement of the limiting groove can further improve the stability of the connecting frame and the bristles after being locked;

5. the flaring of the slot and the arrangement of the ball can ensure that the process of inserting the connecting frame into the slot is smoother.
