Detailed Description

The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.

As shown in fig. 1-3, the circuit board quick fixing and dismounting device comprises a pair of support frames 2 for clamping and fixing the circuit board 1, an L-shaped installation clamping groove 6 is formed in the front face of the support frames 2, a clamping block 3 is arranged above the installation clamping groove 6 in the middle, the clamping block 3 and the support frames 2 are of an integrated structure, and the bottom surface level of the clamping block 3 is parallel to the groove surface of the installation clamping groove 6. Seen from the side, the L-shaped mounting clamping groove 6 only forms a clamping structure at the center position through the bottom surface of the clamping block 3, and the distance between the bottom surface of the clamping block 3 and the groove surface of the mounting clamping groove 6 is only 1-2 mm smaller than the thickness of the circuit board, so that the circuit board 1 can be conveniently and rapidly inserted into the mounting clamping groove 6, and further, the post-stage rapid locking and fixing are facilitated.
