[0032] When the moving plate 2 84 is pulled by the spring 2 92 toward the supporting plate 2 to reset, the placing plate 3 is pulled by the spring 2 92 to reset. At this time, the lower pressing plate 4 has not yet contacted and pressed down with the board. As the lower pressing plate 4 continues to press down, the moving plate 2 84 will move a certain distance so that the pushing end 842 is away from the placing plate 3 for a certain distance, thereby ensuring that the lower pressing plate 4 will contact and press down with the board only after the placing plate 3 is in place, and when the lower pressing plate 4 is lifted, the moving plate 2 84 will not immediately contact and push the placing plate 3 to move. When the pushing end 842 on the moving plate 2 84 contacts with the placing plate 3, the lower pressing plate 4 also rises a certain distance, which can prevent the lower pressing plate 4 from affecting the pushing of the placing plate 3.

[0033] When using the device, the user places the board to be tested into the placement slot 31 on the pushed-out placement plate 3 (the pushed-out placement plate 3 as shown in the figure is the placement plate 3 on the right side of the device base 1, and its driving device 6 is connected to the lower pressing plate 4 on the left side), and then starts the driving device 6, which drives the lower pressing plate 4 connected thereto to move upward. When the lower pressing plate 4 connected to the driving device 6 moves upward, it drives the movable rod 513 connected thereto to move upward, and then drives the driving member 51 matched therewith to run, and then drives another driving member 51 connected to the transmission component 1 52 to run synchronously, so that the other lower pressing plate 4 moves synchronously, and the two lower pressing plates 4 move in opposite directions in an alternating manner when moving; When the lower pressure plate 4 connected to the driving device 6 moves up, it drives the movable plate 1 73 connected thereto to move up, and then drives the gear 2 74 matched thereto to rotate. The rotating gear 2 74 drives the transmission assembly 2 75 to operate through the rotating rod 2 72, and then drives the rotating rod 3 82 to rotate synchronously. The rotating rod 3 82 drives the gear 3 83 to rotate. The rotating gear 3 83 drives the movable plate 2 84 to move linearly. The movable plate 2 84 corresponding to the driving device 6 is driven by the gear 3 83 to be pushed in the direction of the corresponding placement plate 3, which can move the movable plate 2 84 corresponding to the driving device 6 to be placed in the direction of the corresponding placement plate 3. 6, so that the placement plate 3 under the lower pressing plate 4 can be pushed out, so that the user can place the board to be tested into the placement slot 31, and the user can take out the tested board. When the placement plate 3 is pushed out, the plate body 122 on the fixed plate 12 corresponding to the placement plate 3 will also move with the placement plate 3, and the placement plate body 122 drives the guide rod 91 connected thereto to move, and the guide rod 91 squeezes the spring 92 matched therewith through the squeezing end 93 to compress it; When the placement plate 3 corresponding to the driving device 6 is pushed out, the movable plate 2 84 corresponding to the other placement plate 3 on which the board is placed will be driven by the gear 3 83 to move in the direction of the spring 2 92. When the movable plate 2 84 moves in the direction of the spring 2 92, the spring 2 92 corresponding to the movable plate 2 84 releases the compressed force. The spring 2 92 drives the guide rod 91 matched with it to move in the direction of the spring 2 92 through the extrusion end 93. The guide rod 91 drives the plate body 2 122 connected thereto to move together. The plate body 2 122 drives the placement plate 3 to move together through the limiting rod 34. As the movable plate 2 84 moves, the push end 842 on the movable plate 2 84 moves away from the placement plate 3. Afterwards, the spring 2 92 can pull the placement plate 3 to move to the initial test position, so that the ejector pins on the ejector pin module 13 correspond to the perforation positions on the placement plate 3. As the lower pressing plate 4 corresponding to the placement plate 3 moves downward, the lower pressing plate 4 can press the board on the placement plate 3 downward, so that the corresponding placement plate 3 moves downward, so that the ejector pins on the ejector pin module 13 can pass through the perforations and contact the board to test the board. When the board on the placement plate 3 is being tested, the user places the board on another pushed-out placement plate 3 for testing, so that when the equipment is testing the board, it does not affect the user's placement of the next board to be tested, which can effectively improve the testing efficiency of the board.
