It is one of the most basic and important components of the computer and plays a vital role in the entire computer system. The quality of the motherboard determines the stability of the hardware system. The motherboard is closely related to the CPU. Every major upgrade of the CPU will inevitably lead to the replacement of the motherboard. The motherboard is the core of the computer hardware system and the largest printed circuit board in the mainframe.

[0003] In the prior art, for example, Chinese patent number: CN212526421U discloses a clamping device for welding a motherboard of an electronic product, comprising a first plate body and two fixed plates, wherein the upper surface of the first plate body is fixedly connected to a placing plate, the upper surface of the placing plate is provided with a limiting sliding groove, the upper surface of the placing plate is welded with a second plate body and a third plate body from left to right, the inner side wall of the third plate body is threadedly connected to a first threaded rod, one end of the first threaded rod is fixedly connected to a knob, and the other end of the first threaded rod is rotatably connected to a fourth plate body through a bearing, and the fourth plate body and the second plate body are evenly fixedly connected on one side adjacent to the second plate body with a spring, and the mainboard is automatically adjusted and clamped by using the fixed plate to squeeze the spring and other components, and the setting of the fourth plate body is adjusted by rotating the first threaded rod, so that mainboards of different specifications can be adjusted, the operation is simple, and it is convenient for staff to use and convenient for staff to perform welding work on the mainboard.
