The pushing plate 3 moves, and a fixing plate 4 is vertically fixedly installed on the inner wall of the conveying frame 1. A feeding trough 5 is arranged between the fixing plate 4 and the placing frame 2. A limiting groove 6 is vertically opened on the opposite surface of the fixing plate 4 and the placing frame 2. A built-in groove 7 is vertically opened in the middle of the limiting groove 6. The inner wall of the limiting groove 6 is vertically slidably matched with a 匚-shaped connecting plate 8. A plurality of auxiliary rollers 9 are installed on the inner wall of the connecting plate 8 for horizontal rotation at equal intervals. The connecting plate 8 is fixedly connected to the inner wall of the built-in groove 7 through a plurality of horizontally arranged telescopic rods 10. A spring 11 is movably sleeved on the outer wall of the telescopic rod 10. The device is provided with a placing frame 2, and multiple circuit boards are stacked in the technology. The pushing plate 3 is used to cooperate with the spring 11 to push and squeeze the connecting plate 8 to fix the circuit board. The electric push rod 15 can extend a unit length each time.
