Abstract
A blender in the invention includes a handle at one side of a container and having a link rod disposed therein. A microswitch is in a base and an actuating rod is above the microswitch. The link rod has an upper end protruding into a slide groove of the handle and a lower end extending into a lower portion of the container and touched against the actuating rod. When the cover is not closed on the container, the blender cannot work even if a rotary switch is turned on because the electric circuit of the microswitch is broken. When the cover is closed on the container, its push block is lowered to press the link rod down to force the actuating rod to be contacted with the microswitch to form an open electric circuit enabling the blender to work, thereby providing the blender with high security in use.
