Abstract: The present invention discloses a portable ball-containing massage device, which comprises: multiple balls and a body. The body has at least one accommodation surface, which those balls are installed to and can rotate within. Multiple retainers are installed between the accommodation surface and the balls and used to accommodate the balls. The curvature of the accommodation surface and the sizes of the balls may vary to match some portion of the human body. The body may be a base with a handle, a column with a slip-proof element, or a fabric, which can separately provide a holding function or a large-area massage effect for the user.

Abstract: A flytrap including a casing having a trapping area adapted for holding a bait for attracting flies, a flapping mechanism, a holding-down mechanism, and an intermittent action control device, wherein when the driving mechanism is turned on, the holding-down mechanism is moved by a driven member of the driving mechanism to hold down the flapping mechanism, and the intermittent action control device starts counting a predetermined length of time when the driven member is turned to switch off a power control switch in cutting off power supply from the driving mechanism, and the driving mechanism is started again when the counting is ended, causing the the holding-down mechanism to be released from the flapping mechanism, permitting the flapping mechanism to flap attracted flies with a flyflap.
