[0004] With respect to the above-mentioned related technologies, the inventors found that there are at least the following problems in the technologies: since the bottom box protects the cathode device, the bottom box is easily impacted. When the bottom box is frequently impacted with a large impact force, it is easy to deform, thereby reducing the protective effect. Utility Model Content
