The method of servicing a vacuum chamber of claim 1, wherein: firstly, the cavity motor is disassembled from the speed reducer; then the cavity motor is pulled backwards to a lifting position along the first guide rail through the lifting piece; the sliding component slides along with the cavity motor, after the cavity motor is separated from the speed reducer, the lifting appliance lifts the cavity motor upwards through the lifting piece, at the moment, the guide column is separated from the fixed plate, and the fixed plate moves upwards along with the cavity motor, so that the cavity motor is transferred to a designated position.
8. A method of servicing a vacuum chamber as claimed in claim 3, wherein: the cavity motor drives the vacuum cavity door to be far away from the vacuum cavity opening, and the lifting point at the top of the sealing ring retainer is forced by the lifting appliance to drive the sealing ring retainer to move towards the direction far away from the vacuum cavity opening, so that the hanging point is separated from the guide hanging hole, and the sealing ring retainer can be lifted upwards by the lifting appliance, so that the sealing ring retainer is brought out of the glove box, and the maintenance is convenient.
9. The method of repairing a vacuum chamber according to claim 5, wherein: firstly, hanging a lifting hook of a lifting appliance on a lifting ring; then the compressing hand wheel component is opened to separate the clamping flange from the peeping barrel; and finally, lifting the clamping flange upwards to transfer to a proper position through a lifting appliance, opening the clamping flange, and replacing peeping glass.
10. A glove box vacuum cavity apparatus comprising a glove box, a vacuum cavity as claimed in any one of claims 1 to 6 and a spreader disposed on top of the glove box.
