What precautions should be taken when using a hand hammer?

Friends must be familiar with the hand hammer. It is a tool often used in daily life and production. Hand hammers bring a lot of convenience to our lives, and there are many things that need to be paid attention to when using them.
When using it, please note that the hammer head and hammer must be firmly connected to the wooden handle. If it is found to be loose, it is prohibited to use it. If you want the hand hammer to have a certain degree of elasticity when hitting nails, you need to grasp the position of the handle, which needs to be slightly narrower at the top. In order not to hurt innocent people, you must pay attention to the fact that no one is standing in front, back, left or right when using the hand hammer.
