Abstract: A hammer structure includes a hammer body, at least one hitting block, a compression spring, and a shaft. The hammer body has a radial through hole. The hitting block includes a mounting portion having an accommodating hole. The compression spring is accommodated in the accommodating hole. The shaft is inserted through the compression spring so that it can be elastically extended and retracted via the compression spring. The mounting portion of the hitting block is screwed to the end of the hammer body. The shaft counteracts an elastic force of the compression spring to be partially engaged in the radial through hole. The hammer structure can prevent the hitting block screwed to a mounting groove of the hammer body from being loosened due to strong impact and vibration in the hitting process, so as to fix the hitting block and avoid damage effectively.
