[0007] By adopting the above technical scheme, when the striking head strikes the object, the reaction force of the striking head will be absorbed by the striking shock-absorbing piece, and the other part of the shock force will be transmitted to the hammer handle through the hammer head. In the process of transmission along the hammer handle, the shock-absorbing holes will weaken the conduction of the shock wave, so that the shock force is weakened. When the shock force is transmitted to the end of the hammer handle away from the hammer head, the hand shock-absorbing piece will further absorb the shock force on the hammer handle, thereby weakening the shock force transmitted to the worker's hand, which is beneficial to reduce the possibility of the worker's hand being damaged.

[0019] By adopting the technical scheme, the worker fixes the shock-absorbing rubber box on the hammer head, when the instant of the impact head hitting the object, the vibration force transmitted to the hammer head will make the steel balls in the shock-absorbing rubber box shake or jump, the shaking or jumping steel balls absorb the vibration force of the hammer head through the friction between the steel balls, so as to reduce the transmission of the vibration force to the hammer handle, and reduce the possibility of the hammer head jumping up, and further increase the weight of the hammer head, so that the nail is more easily knocked into the object.
[0020] Optionally, the shock-absorbing rubber box is provided with a protrusion in U-shaped cross section, the hammer head is located between the protrusion and the shock-absorbing rubber box, the protrusion is located on the side of the hammer head away from the hammer handle, and the protrusion is provided with a lever block.
[0021] By adopting the technical scheme, for the long nail, the lever block can facilitate the worker to take out the nail more easily.
[0022] In summary, the present application has at least one of the following beneficial technical effects:
[0023] 1. When the impact head hits the object, the reaction force of the impact head hitting will be absorbed by the impact shock-absorbing part, and the other part of the vibration force will be transmitted to the hammer handle through the hammer head. In the process of transmission along the hammer handle, the shock-absorbing hole will weaken the conduction of the shock wave, so that the vibration force is weakened. When the vibration force is transmitted to the end of the hammer handle away from the hammer head, the hand shock-absorbing part will further absorb the vibration force on the hammer handle, so as to weaken the vibration force transmitted to the worker's hand, which is beneficial to reduce the possibility of damage to the worker's hand;

When the impact head hits the object, the reaction force of the impact makes the impact head extrude the spring washer, and the spring washer deforms elastically. At the same time, the pad deforms, and the deformed pad absorbs the vibration force from the impact head, so as to weaken the vibration force transmitted to the hammer head;
[0025] 3. The worker fixes the shock-absorbing rubber box on the hammer head, when the instant of the impact head hitting the object, the vibration force transmitted to the hammer head will make the steel balls in the shock-absorbing rubber box shake or jump, the shaking or jumping steel balls absorb the vibration force of the hammer head through the friction between the steel balls, so as to reduce the transmission of the vibration force to the hammer handle, and reduce the possibility of the hammer head jumping up, and further increase the weight of the hammer head, so that the nail is more easily knocked into the object.

[0037] When the impact head 3 hits the object, the reaction force of the impact head 3 hitting the object will make the gasket 41 deform, and the deformed gasket 41 will absorb the vibration force from the impact head 3, and at the same time, the impact head 3 will press the spring gasket 44, and the spring gasket 44 will elastically deform.
[0038] The vibration force from the impact head 3 is absorbed in part, and the other part of the vibration force will be transmitted to the hammer handle 2 through the hammer head 1, and in the process of transmitting the vibration force along the hammer handle 2, the shock-absorbing hole 5 will weaken the conduction of the shock wave, so that the vibration force is weakened.
