[0027] The protrusion 207 and the slider 218 slide inside the groove respectively, thereby ensuring the stability of the movement of the connecting plate 206 and the moving block 217.

[0028] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth to explain in detail that the push blocks 211 are symmetrically fixedly connected to the left and right sides of the back of the connecting plate 206, and the opposite surfaces of the push block 211 and the moving block 217 are respectively provided with inclined surfaces with the same angle;

[0029] The inclined surface makes it easy for the push block 211 to push the moving block 217 , thereby driving the positioning block 214 to move, so that the positioning block 214 is separated from the interior of the positioning groove 219 .

[0030] Further as Figure 2 , Figure 3 and Figure 4 As shown, it is worth to explain in detail that positioning grooves 219 are symmetrically opened on both sides of the connecting column 202, and the positioning grooves 219 are adapted to the positioning blocks 214;

[0032] According to the above working process, it can be known that: through the setting of the connecting mechanism 2, the positioning block 214 can be inserted into the positioning groove 219, so that the connecting column 202 can be stably fixed inside the fixing block 201, and the two circuit board bodies 1 are connected to improve the stability of the circuit board body 1, and no external tools are required, the operation is convenient, and it is not affected by the outside world.

When it is necessary to release the limit on the pressing plate 209, rotate the limit block 305 with force.
