Abstract
An improvement for mole chaser includes a stem houses a motor to drive a rotary means within a hollow impact unit. The impact unit has a plural number of curved bulges located therein. The rotary unit has movable impact members eccentrically located thereon. Motor rotation will drive the impact members hitting the bulges because of centrifugal force and cause the stem to produce strong vibration and audio frequency to scare away the moles. The eccentric impact member may hit the bulges and bounce back without damage.
