When in use, the staff will fix the installed copper lead frame inside the equipment through the fixing plate, thereby achieving the purpose of fixing and avoiding loosening caused by vibration during use. At the same time, through the setting of the retaining column, when in use, since the outer frame bar and the inner frame bar are connected by several small structures, the setting of the retaining column not only enhances the connection relationship between the two mechanisms, but also has a certain pulling effect. When placed in daily use, the chip offset occurs, and the setting of the connection hole is in direct contact with the connection mechanism of the device itself during installation, thereby achieving the effect of facilitating the interaction with the chip when the device is running, and avoiding the occurrence of short circuits.
