The present invention relates to a hammer having a cushioning and reinforcing structure, and more remedy to improve the fixing according to the connection of the hammer head and the bag, and to reduce the fatigue of the operator by offsetting the impact from the head by the impact On the other hand, by reinforcing the boundary portion of the head and the bag is intended to prevent deformation or break of the bag as much as possible.

In general, a hammer (Hemmer) is a blow tool used in the hand, as a typical example is used for the purpose of hitting the material, or other damage, or pull out the nail according to the shape. Types of hammers include rubber hammers, synthetic resins, or wood hammers, depending on the material of the head. Representative hammers may be representative of products made of metal materials.

Hammers have been produced by forging for a long time, as shown in Figure 1, the center of the metal head 12 is formed with a circular or rectangular bag insertion hole 11, the strength of the bag insertion hole (11) It is used by inserting and inserting a bag 14 made of a material, such as strong roots and good elasticity, birch.

In general, in the use of a hammer, a head made of a metal material acts to force the head to be separated by a force hitting to nail or otherwise break or cut an object. In order to prevent such a point, the joint part of the bag guided to the head insertion hole of the head is fitted with a wedge of a separate wood or screw on the upper part to enlarge the volume of the upper part of the bag, and then an adhesive such as an epoxy resin is hardened thereon. It has been used for the purpose of preventing departure.

Alternatively, a through hole is formed from one side of the head, and a coupling hole is formed on the bag side to penetrate the fastening screw from the outside of the head, and then a solution that fundamentally solves the detachment of the head and the bag by screwing the nut is attempted. However, such an example has a disadvantage in that it is only suitable for hammers having a relatively small size, but not for hammers for cutting concrete or cutting thick steel.

The fastening screw for fixing the head and the bag has a problem that it is relatively difficult to apply a heavy hammer because there is a closed end that breaks in a state where the impact is relatively strong. It is transmitted to the hand held by the worker, such a shock transmission was accompanied by a shock to the wrist, elbow, shoulder, etc. There was a problem in giving the worker's body in a long time use.

Such an impact is a case where the stress is concentrated at the boundary point between the hammer head and the sack part and the damage of this part is increased. This is because the shock absorption from the impact of the head is not properly made, the problem with the use of the hammer was a defect that the head is easily detached from the bag, or the boundary is broken as described above.

The present invention is to solve the conventional problems as described above, to improve the fixing according to the connection of the head of the hammer and the bag, and to reduce the fatigue of the operator by offsetting the impact received from the head by the impact, The purpose is to strengthen the boundary of the bag to prevent deformation or breakage of the bag as much as possible.

According to the present invention for achieving the above object, in the hammer by inserting one end of the bag made of wood material into the bag insertion hole in the center of the metal head,

The guide jaw is inserted through the front of the bag insertion hole is extended to the front, and a fixed frame body is installed to be inserted longer than the insertion section of the bag to be inserted from the rear of the bag insertion hole, and the recess groove in the upper and lower sides from the bag insertion hole It is extended, and the wedge-shaped cushioning material for press-fitting and fixing the fixed frame body from the bag insertion hole is inserted into the recessed groove, and the resin is filled and hardened to fix the fixed frame body and the tip of the bag in front of the bag insertion hole. A hammer having a shock absorbing and reinforcing structure is provided.
