摘要： A hand held grinder includes a hollow cowl and a vibration absorber mounted in the cowl. The vibration absorber includes a longitudinal through hole defined through center parallel to the axis of the cowl, and a radial through hole defined in the vibration absorber. The radial through hole communicates with the longitudinal through hole. A socket is defined in the vibration absorber and communicates with the longitudinal through hole and the radial through hole. A transmission device penetrates the vibration absorber and forms a pivot pivotally received in the socket of the vibration absorber. The transmission device has a hollow threaded shaft formed on the exterior end and a neck formed on the other end. A main shaft eccentrically connects and drives the transmission device. The main shaft includes an enlarged external end and a shank extending from the enlarged external end along the axis of the main shaft. The enlarged external end has a diameter that is greater than that of the shank and an end eccentrically containing an eccentric recess to receive the neck of the transmission device. A hollow central body is connected to the cowl and receives the main shaft therein. A connecting shaft is connected to the free end of the shank of the main shaft. A hollow root is connected to the other end of the central body and receives the connecting shaft therein.
