Problems solved by technology

[0003] For example, the Chinese patent application number (CN201620255316.X) discloses a servo driver, including a box body, a cooling device, a power board, a capacitor fixing plate, and a button panel, and the box body includes an outer shell, an upper cover plate, and a middle partition , a first side plate and a second side plate, the middle partition divides the outer casing into a cooling cavity and an installation cavity, the power board, the capacitor fixing plate and the button panel are all arranged in the installation cavity, and the first side The plate and the second side plate are respectively covered on both sides of the outer shell, wherein a fixed box is also included, a window is opened on the upper cover, the key panel is fixed in the fixed box, and the fixed box is fixed in the On the capacitor fixing plate, the button panel exposes the upper part of the button panel outside the upper cover through the window on the upper cover. It can be seen that the internal capacitor of the driver in this application is installed and fixed through the capacitor fixing plate, and it needs to be fixed. When the capacitor is disassembled, it is necessary to connect and remove the fixing box and other accessories, so its assembly and disassembly are very inconvenient and need to be improved
