The LED lights are connected to the circuit board unit inside the housing through wire harnesses, and the indicator lights are lit when the device works.

[0046] In this embodiment, there are three holes on the bottom plate, and there are three threaded holes on the corresponding cushion block. The cushion block is fixed to the bottom plate by three screws.

[0047] In this embodiment, there are two holes on the side of the buckle, and there are two screw holes on the side of the upper half of the spring pin bracket corresponding to them. The upper half of the spring pin bracket is fixed to the side of the buckle by two screws and can move up and down with the buckle.

It is used to support the spring pin bracket and the buckle. When pressing the cylinder on the upper half of the spring pin bracket downward, the buckle and the spring pins will move downward at the same time. At this time, the spring pins will contact the data reading points on the storage board placed on the cushion block. At the same time, when the inner pins of the spring pins receive an upward force from the storage board, they will move upward. After the buckle moves downward a certain distance, it locks. At this time, it is ensured that the inner pins of the spring pins are in good contact with the data reading points on the storage board.

[0050] When the device works, the storage board is inserted through the hole on the side of the middle frame, and then the button on the spring pin bracket 3005 is pressed downward. The spring pin bracket 3005 will drive the buckle 3004 and the spring pins 3006 to move downward together. The spring under the spring pin bracket 3005 is compressed by force. After the spring pins 3006 contact the data reading points on the storage board, the inner pins of the spring pins 3006 remain stationary, and the middle shell of the spring pins 3006 continues to move downward with the spring pin bracket 3005. The middle shell applies a downward force to the inner pins to ensure good contact between the spring pins 3006 and the data reading points on the storage board. When the buckle 3004 moves downward to the locking position, the buckle locks. At this time, the button 3021 is released, and the spring pins 3006 are pressed on the data reading points of the storage board. A USB wire harness is inserted into the USB interface on the other side of the middle frame, and the other end is connected to the PC. At this time, through the spring pins and the wire harness at their tails, the interface of the storage board can be connected to the second PCB board after passing through the first PCB board. The second PCB board transfers the interface to a USB interface, and then is connected to the PC through the USB interface board and the external USB wire harness. At this time, the PC can be used to perform data reading and writing operations on the storage board.

[0051] After the operation is completed, press the button 3021 downward again. The spring pin bracket 3005 drives the latch and the spring pin 3006 to move downward together. When the latch 3004 moves downward to the release position, the latch opens. At this time, release the button, and the spring pin bracket 3005 is pushed upward under the action of the elastic force of the two springs, driving the spring pin 3006 to move upward, and the spring pin 3006 disconnects from the data reading point on the storage board.
