Description
Technical Field
The invention relates to a hammer head, in particular to a hammer head capable of increasing instantaneous hammering force.
Background
The hammer head is a small tool necessary for work and life, and even a main working tool in some working occasions. The hammer head completes the operation by instant hammering force, and the larger the hammer head is, the larger the hammering force is generally. However, the larger the hammer head, the more laborious it is to use, and especially using the hammer head for a long time is a very labor-intensive operation.
CN210099938U discloses a labor-saving hammer head, wherein a hollow slide way is provided in a handle, a slide block is provided in the slide way, when a user throws out the hammer head, the slide block is thrown out, so as to increase the power when the hammer head body falls down, and increase the instant acting force of the hammer head, which saves labor force compared with a common hammer head. However, the speed of the sliding block thrown into the hammer head body in the hollow slide way is high, the impact force on the hammer head body is large, and a part of energy can increase the hammering force during hammering, but the hammer head body can be damaged; moreover, the slider slides back and forth to impact the handle and the hammer head body, so that the hammer head is damaged, and the user feels uncomfortable.
CN203092497U discloses a hammer, which includes a hammer head and a handle, wherein a counterweight part is provided in the handle, the counterweight part can move along the handle, one end of the handle is provided with an adsorption element to make the counterweight part reside at one end of the user, and the other end is provided with a spring to help the counterweight part to reset and have a buffer effect, so as to improve the comfort level of the user. The hammer accumulates energy by the action of gravity of the weight portion and increases the hammering force at the moment of hammering. However, although this hammer is labor-saving compared to a conventional hammer, the weight portion slides back and forth, and vibration and friction are generated.
Therefore, it is very significant to manufacture a hammer head capable of increasing the instantaneous hammering force, reducing the labor intensity, and improving the operation comfort compared with the prior art.
