The top of described leg is provided with socle, and socle passes through hole corresponding in the detent, contacts with the roller of rolling wheel support assembly in placing detent.

The top of described leg is provided with socle, and itself and detent are provided with sealing ring between the bottom, and socle passes corresponding through hole in sealing ring and the detent, contacts with roller in the detent.

The bottom of described detent is provided with support, and the weight sensor bottom is provided with sensor stand, and the weight sensor assembly is fixedlyed connected with the support on the detent bottom by sensor stand.

Described support is stepped or step-like, offers installing hole on the support, and the peripheral relevant position of sensor stand is provided with lug, offers installing hole on the lug, and support and sensor cluster are connected with support plate by securing member.

The present invention only utilizes a weight sensor and is fixed on the non-geometric center position, support plate bottom, directly use a fulcrum of supporting microwave oven rotating disk, the weight induction that acts on the glass plate is come out, and do not need and the transmission mechanism share components, therefore it is simple and reasonable, only need offer through hole at support plate simultaneously, to realize that power is passed to weight sensor from the socle on the leg, the effective microwave interference that produces of shielded microwave oven, the more accurate weight that obtains cooking food.
