In daily life, we often use hammers, but hammers are dangerous tools that can harm ourselves if we are not careful. The weight of a hammer needs to be suitable for the workpiece, material, and function, as being too heavy or too light can create hidden dangers.
When using a hammer, the connection between the hammer head and the wooden handle of the hammer must be firm. If there is any looseness, it should be immediately wedged and tightened or replaced with a new handle. The length of the wooden handle of the hammer must be moderate. Generally, the most suitable length is to hold the hammer head by hand, and the length of the forearm should be equal to the length of the hammer; When smaller impacts are needed, hand swing method can be used, and when stronger impacts are needed, arm swing method should be used; When using the arm swing method, attention should be paid to the movement curve of the hammer head, and the handle of the hand hammer should not be contaminated with grease. Safety first, be sure to pay attention to safety when using a hammer.
