Mechanisms, devices, apparatus, systems and methods of installing ceiling fan motor housings to ceiling mounted plates without using loose fasteners such as screws, and the like. A plate having a plurality of slots about the perimeter can be pre-mounted to a ceiling. A motor housing having clips on interior perimeter edges of the base can be positioned so that the clips are inserted into the slots. Next, the motor housing can be twisted clockwise until the clips lock to the slots allowing the ceiling fan motor to be hung without any loose fasteners. The twist-lock eliminates unsightly fasteners, such as screws underneath the housing, quickens installation time, and is easier and safer than traditional ceiling fan installation techniques.

The invention belongs to the technical field of plastic plate processing, in particular to a plastic part processing device. The plastic part processing device comprises a processing table and a driving unit. A U-shaped pipe is arranged above the processing table, and the inner part of the U-shaped pipe is connected with a fan. The lower end of the fan is connected with a vertical rod, a swingingarm is hinged on the vertical rod, and a dedusting brush head is arranged at the bottom of the swinging arm. A branch pipe is arranged on one side of the U-shaped pipe, and a rotation shaft is arranged above the U-shaped pipe and is connected with the driving unit. A main worm wheel is arranged at the upper end of the rotation shaft, and a cross rod is connected on the rotation shaft and is connected with a ceiling fan. The ceiling fan is connected with the rotation shaft, and a connecting rod is arranged at the upper end of the ceiling fan. A sleeve is arranged at the upper end of the connecting rod, and a cross shaft is arranged in the sleeve. The two ends of the cross shaft are respectively connected with a first worm and a second worm. A first worm wheel belt is connected with a scrubbing roller, the scrubbing roller is twined with a tape, and a scraping bar is arranged on the tape. A film unfolding roller is arranged on the processing table. According to the technical scheme, theplastic part processing device can fast clean the surface of a plastic plate and mulching a film.
