[0025] In this utility model, by setting the cooperation of each component in the locking mechanism 5, rotating the bolt 55 causes the bolt 55 to move, thereby squeezing the L-shaped frame 52 to slide on the T-shaped frame 51. At this time, the pressing block 53 fixed on the L-shaped frame 52 fits with the convex column 4, so as to lock the convex column 4 and the circuit board placed on the working surface 3, and effectively prevent the circuit board from shifting during splitting.

[0026] The lower end of the bolt 55 is fixedly in contact with the L-shaped frame 52, and the vertical end of the L-shaped frame 52 is fixedly connected with a pressing block 53.

[0027] The L-shaped frame 52 can drive the pressing block 53 to move, so that the pressing block 53 fits against the convex column 4 to lock the circuit board.

[0028] A groove 6 is formed on the working surface 3, and a blanking mechanism 7 for easily ejecting the cut circuit board is provided on the groove 6 and the workbench 2 together.

[0029] The top block 75 in the blanking mechanism 7 can be installed and guided through the groove 6.
