Abstract
The utility model provides a safe structure with an active protection for a kneader, comprising a kneader top-cover, a kneader cover-board which is positioned on the kneader top-cover, a contact structure and a power safety-switch which are arranged inside for starting the machine to operate. A separate safety-switch device which is required by other kneaders is not needed, and the kneader cover-board is designed and formed to closure, thereby avoiding any possibility that consumers and users contact cutting tools inside the machine and the like, and preventing foreign matters from falling down. When the cover-board is opened, on one hand, the effects of starting machine and normal operating can be achieved, on the other hand, the situation that users employ force to put in the foreign matters can be avoided. The inner structure of the utility model provides a double safety protection, which enables the machine to stop operating immediately and further improves the use security of consumers.
