In addition, the hammer bag is mitigated to reduce a significant impact caused by the collision between the hammer head and the striking body, thereby minimizing the impact transmitted to the operator's hand, The present invention provides a hammer completed with a focus on the technical problem in that the hammer bag can be prevented from being damaged by an impact caused by a collision between the hammer head and the striking body.

According to an aspect of the present invention, there is provided a hammer head comprising: a hammer head having a fixing groove and a hole for engaging the hammer head, the hammer head having an upper end inserted into the hole, The fixing body of the urethane bolt is inserted into the upper end of the hollow portion of the hammer bag. The fixing body of the urethane bolt has an outer diameter larger than the inner diameter of the hollow portion of the hammer bag A plurality of crimping wedges are formed so that the wedge wing of the crimping wedge is pressed against the inner wall of the hollow portion of the hammer bag to double the fixing force by the urethane bolt and the stopper of the hammer hanger and the holding handle at the lower end are combined. .

The hammer presented in the present invention adopts a synthetic resin hammer bag. By constructing the hammer bag with the synthetic resin of elastic material, it is possible not only to improve the working efficiency by generating quick acceleration even when swinging the hammer with a small force The hammer bag is mitigated to minimize the impact transmitted to the operator's hand, thereby reducing the fatigue of the operator. The hammer bag is made of an elastic material, It is possible to prevent the hammer bag from being damaged by the impact generated by the collision with the striking object.

In addition, the present invention has a very simple structure for combining the hammer head and the hammer bag, which enables mass production at a low cost and facilitates the replacement of the coupled components, which is advantageous in terms of maintenance. The expected effect is really a good idea.
