Abstract: A juicer having safety mechanism with its handle is disclosed, where the handle is used to buckle its cover. A contact switch is fixed in the body of the juicer and connected in series with a starting circuit of the juicer motor. As the handle buckles the cover, a moving element with a through hole is forced to move down, which enables the through hole to be aligned with a contact member of the contact switch. During the handle buckling the cover, the prop pillar is held to pass through the through hole of the moving element to reach the contact member of the contact switch for turning on the contact switch. On the other hand, if either the cover or the handle is not in place, the contact switch is in power disconnection. Accordingly, the objective of the safety protection can be truly fulfilled.
