The invention discloses practical deduster equipment comprising a power transmission base. The bottom part of the power transmission base is fixedly provided with a sucking disc. The left and right sides of the sucking disc are respectively provided with a lifting ring. The left end surface of the power transmission base is provided with a jack. The right end part of the jack is provided with a power transmission port. The bottom end part of the jack is provided with a first slide cavity which is communicated with the jack. The power transmission base is provided with a second slide cavity above the jack. The power transmission base is provided with a turning slot on the right end of the jack. The turning slot is provided with an operation device. A slide frame is smoothly arranged in thejack in a left-and-right direction. The structure is simple, the production cost is low and power supply is safe and stable so that the accident of electric shock can be effectively eliminated, automatic connection and disconnection of the power connection head and the power transmission port can be realized, the situation that the power connection head of the plug of the deduster is separated from the power transmission port because of mistakenly hitting and colliding the electric wire can be avoided, and the use requirements of the deduster can be met.
