[0043] In this embodiment, since the top of the base 1 is provided with the gasket 5 for supporting the circuit board, when the inclined sliding blocks 22 press down the circuit board, the circuit board is bent. Therefore, it can be found that Figure 3 by machining the top of the sliding table 21 with a horizontal surface near one side of the gasket 5, and fixedly connecting the second buffer pad 16 at the horizontal surface, with the top surface of the second buffer pad 16 flush with the top surface of the gasket 5, the edge of the circuit board can be supported, avoiding the circuit board being bent, thereby further improving the processing precision of the circuit board.

[0046] Finally, after the circuit board is processed, the driving motor 31 is controlled to be reversed, so that the two positioning clamps 2 move away from the circuit board, so that the circuit board can be easily taken out.

[0047] The embodiments of the specific implementation are the preferred embodiments of the utility model, and do not limit the protection scope of the utility model, so that: any equivalent changes made according to the structure, shape, principle of the utility model should be covered within the protection scope of the utility model.
