The front end of the lifting rod passes through the strip-shaped opening, and a lifting plate is arranged on the lifting rod. The front end of the lifting plate is in contact with the front end of the chamber in a butt manner; the brush assembly is in plug-in fit with the slot. When it is necessary for the brush assembly to clean the piano keys, press the lifting rod backward, so that the front end of the lifting plate moves away from the front end of the chamber. Then slide the lifting rod downward, so that the moving block drives the brush assembly to move downward in cooperation with the slot, so that the brush assembly extends below the housing through the through port. Then release the pressing on the lifting rod, so that the lifting rod drives the front end of the lifting plate to be in contact with the front end of the chamber again under the cooperation of the spring force, improving stability.

[0008] Preferably, the brush assembly includes flexible bristles and a plug rod. The plug rod is provided with flexible bristles, and the flexible bristles are in plug-in fit with the slot; the staff can select flexible bristles of different shapes according to the cleaning needs, and then insert one end of the plug rod into the slot. The outer side wall of the plug rod is in frictional contact with the slot, and the replacement is convenient.

[0009] Preferably, it further includes a pressing handle, and a pressing handle is arranged at the front end of the lifting rod; the staff presses the lifting rod backward through the pressing handle, improving the comfort of pressing.

[0010] Preferably, a protective coating is arranged on the outer side wall of the housing; the staff holds the housing with the cooperation of the protective coating, reducing the situation of the housing slipping out of the hand.

[0011] Preferably, it further includes a first anti-slip convex block, and multiple groups of first anti-slip convex blocks are respectively arranged on both sides of the front end of the lifting plate; the front end of the lifting plate is in contact with the front end of the chamber through multiple groups of first anti-slip convex blocks, improving stability.
