As shown in fig. 1 and 2, a printed circuit board fixture includes C-shaped clamps 100 clamped on two opposite sides of a circuit board, the two C-shaped clamps 100 are disposed oppositely, and both the two C-shaped clamps 100 are provided with a rotating shaft 240, the rotating shaft 240 is inserted into the upper end of a supporting column 200, and the rotating shaft 240 is rotatably connected with the supporting column 200 but cannot be displaced relatively. A clamping piece 110 is arranged inside the C-shaped clamp 100, the clamping piece 110 is circular, an adjusting rod 120 is arranged on the upper surface of the clamping piece 110, the upper end of the adjusting rod 120 penetrates out of the side face of the C-shaped clamp 100, the adjusting rod 120 is a screw rod, and the adjusting rod 120 is in threaded connection with the side wall of the C-shaped clamp 100. The side of the clamping piece 110 away from the adjusting rod 120 and the side of the C-shaped clamp 100 form a clamping space for clamping the circuit board. The size of the clamping space can be changed by rotating the adjusting lever 120, so that the C-shaped clamp 100 can clamp circuit boards with different thicknesses.

The base 300 is detachably arranged at the lower end of the support columns 200, and the transverse distance rods 400 are movably arranged at the lower ends of the two support columns 200 in a penetrating manner. The base 300 serves as a support for the support column 200. The distance bar 400 is disposed between the two support columns 200 to integrate the two support columns 200, and the distance between the two support columns 200 can be changed to adjust the distance between the two support columns 200 according to the length of the circuit board.

The limiting rod 210 is movably inserted into one side of the supporting column 200 far away from the C-shaped clamp 100, the end surface of the limiting rod 210 is octagonal, and the end of the rotating shaft 240 facing the limiting rod 210 is provided with an octagonal groove 220. The octagonal groove 220 is matched with the limiting rod 210, when the limiting rod 210 is inserted into the octagonal groove 220, the rotation of the rotating shaft 240 is limited due to the interference of the limiting rod 210 and the octagonal side wall, the rotation of the C-shaped clamp 100 is also limited, namely, the angle of the maintenance surface of the clamped circuit board is fixed, and the maintenance of the circuit board is facilitated. When the restraining bar 210 is disengaged from the octagonal slot 220, the C-clamp 100 is in a rotatable position, which allows the circuit board's service face orientation to be adjusted.
