In fact, in life, many people prefer to challenge this tiny thing, or overestimate the fineness of their hands, thinking that they can insert their fingers and take them out perfectly. As a result, they overestimated their abilities and got their fingers stuck. After the incident, the teacher also helped to take it out, but because the space of this lock was relatively small, the teacher could not take it out, and finally called the fire brigade. Firefighters came to remove the lock with a screwdriver and cut it with other tools, finally saving the fingers of two students.
Because I was afraid of cutting the students' fingers, I put a metal gasket in the gap between the lock and the fingers in advance, and finally cut the lock under the careful circumstances of firefighters. These two children are particularly naughty. I hope everyone will pay attention to them. The older the desks and chairs, the more curious the children will be. No matter how strong the school's awareness of prevention is, it can't resist these students' easy attempts, so the principal can intervene in the management of students.
Finally, I hope that all students can pay attention to it, and parents should always tell their children these things. Don't let their children try such dangerous things, they can easily lose themselves. In addition, the school should also organize class meetings regularly to tell students what to touch and what not to touch. Once there are serious consequences, it will be unimaginable and even lead to finger bleeding, including other parts.
