New description: [New technical field] This is a test device for circuit boards, especially a test board for circuit boards that can make the circuit board evenly stressed and the design direction is not limited. [Prior Art] In order to ensure the factory quality of the board, after the printed circuit board is printed, it is necessary to check whether the loop of the circuit is normal. At this time, the board needs to be tested on a test fixture. The existing circuit board test fixture generally includes a base and an upper cover, and a plurality of probes including a compression elastic, a probe and a wire are arranged on the top surface of the base, and the probes are placed on a carrier board, and the probes are placed on a carrier board. The circuit board to be tested is placed on the carrier board, and then the upper cover is overlaid on the board, and the probe is in contact with the board for detection. Precisely, the upper cover and the base of the existing circuit board test fixture are picked up by the rear end pivot. Therefore, a pivot of the rear end of the upper jaw is pivoted, so that the design is easy to derive several missing: 1 · The upper cover can be folded The opening angle is small, making the board difficult to place and remove. 2. When the upper cover is closed, the circuit board and the probe are first contacted at the near end;

It is necessary to further improve the circuit board that has been opened and deflected at the rear end of the shell. [New content] In order to improve the above-mentioned defects, the main purpose of this creation is to provide a circuit board test fixture which can press the upper cover horizontally to make the average force of each probe and the probe position design is not limited.
