At present, (4) brain equipment, whether it is a desktop type, a type-like computer, or a server, must be equipped with a motherboard inside, with the core components of the computer system, so that the central processing sector connected to the domain board "CHJ", memory module, control interface card (ρα (4)) and other computer peripheral hardware: The peripheral function of the peripheral hardware can be smoothly executed. And the common fixed field _ mode is to set a plurality of conductive copper pillars on the housing of the electric appliance. As a fixed component, the motherboard has a plurality of through holes corresponding to the copper pillars. The motherboard is placed on the copper column and maintains the "suitable spacing" between the casing and the outer hole of the domain plate by a plurality of bolts, and is locked on the copper: so that the plate is made of copper The column generates a __suspension to avoid short circuit between the fresh foot contact on the back of the motherboard and the housing. In the traditional way of locking and fixing the main board by the copper column, in the process of loading and unloading the main board, the user repeatedly repeats the turtle lock and unloading action, which is quite time-consuming and complicated, and the actual fairy is not convenient. In the past, electronic devices required light objects to be small, and too many _ column numbers would occupy too much area of the motherboard, resulting in a peach (lay(10)) 主 on the main board, and the electronic material (4) material could not be made. 200920228 Therefore, in recent years, a thumb screw that can be directly turned by a finger has been developed as a positioning member for fixing a main board, thereby greatly reducing the number of copper posts used, thereby solving the problem of fixing the main board by the copper column lock. The problem that arises. Please refer to "Figure 1" for the stereoscopic decomposition of the thumb screw, circuit board and case in the prior art. The casing 10 has a plurality of positioning columns n and a screw hole 61, wherein each of the fixed columns 11 is provided with a -12. The f-plate 2Q has a plurality of positioning holes 21 corresponding to the positioning post 11. Each of the positioning holes 21 has a gourd shape and has a wide section 22 and a narrow section 23, and the front end of the positioning post n passes through the positioning hole 21 by the wide section 22. Thus, the circuit board 20 can be slid on the casing 1 by the positioning post u, and the narrow section 23 of the clamping hole 21 is fitted into the neck portion 12 of the positioning post u. Thereafter, the circuit board 2 can be fixed to the casing 10 by passing the thumb screw 60 through the circuit board 20 and screwing it into the screw hole 61 μ. *However, the marriage refers to the screw to fix the motherboard, which is still the screw locking method. The process of unloading the main board is complicated, not only the _ too long, but also the cost of the plum screw is higher than the price of the traditional bolt. Due to the increase in material costs and labor costs. Therefore, how to truly implement the SCTewless method of fixing the host_installation position, and the quick and convenient loading and unloading of the main spares by the users of the money is a problem that the technicians in the field of the current field are trying to overcome.
