[0022] A rubber pad is embedded in the bottom end of the pressure ring 20, and a silicone pad is bonded to the outer side of the fixed column 18 at the top end of the moving plate 10;

[0023] Specifically, Figure 1 , Figure 2 As shown, circuit board products are generally fixed and installed by screws, so screw holes are opened at some positions on the circuit board. When the device is used, the rotating rod 3 can be rotated, and the cooperation between the active bevel gear 15 and the driven bevel gear 14 causes the bidirectional threaded rod 29 to rotate, so that the two moving bars 16 move toward each other and change the distance between the two. Then, the position of the moving plate 10 is changed by the cooperation between the movable block 24 and the groove 13, which plays a role in adjusting the position of the fixing column 18, so that all multiple fixing columns 18 can pass through the screw holes on the circuit board. When they have all passed through, the rubber sleeve 19 is put on the outside of the fixing column 18, and the circuit board is gently pressed with the pressure ring 20, so that different types of circuit boards can be quickly fixed. After placement is completed, the circuit board can be sent into the accommodating cavity 4 together with the placement plate 2 for storage. One end of the outer wall of the placement plate 2 can be embedded with an erasable board for recording the circuit board model for subsequent retrieval.

[0024] Two empty slots 23 are provided inside the groove 13, and the inner wall of the empty slot 23 is bonded with an anti-skid pad, a rotating shaft 25 is installed at the bottom end of the movable block 24 through a rotating shaft, and the top end of the rotating shaft 25 extends to the top of the fixed column 18 and is installed with a rotating block 17, a sliding sleeve 26 is sleeved on the outer wall of the rotating shaft 25 inside the movable block 24, and transmission rods 27 are installed on both sides of the sliding sleeve 26 through hinges, and a movable plate 28 is installed at one end of the transmission rod 27 through a hinge, and two connecting rods 22 are fixed at one end of the movable plate 28, and the two connecting rods 22 extend to the inside of the empty slot 23 and are installed with an extrusion plate 21;

[0025] The outer wall of the rotating shaft 25 inside the movable block 24 is provided with an external thread, and the inner wall of the sliding sleeve 26 is provided with an internal thread matching therewith;

[0026] Specifically, Figure 4 and Figure 5 As shown, when the fixed column 18 is moved, after the fixed column 18 is moved to a suitable position, the rotating block 17 can be rotated to drive the rotating shaft 25 to rotate. Under the threaded cooperation of the rotating shaft 25 and the sliding sleeve 26, the sliding sleeve 26 is caused to move directionally along the outer wall of the rotating shaft 25. When the sliding sleeve 26 moves toward the moving bar 16, it pushes the movable plate 28 to move through the transmission rod 27, so that the movable plate 28 drives the extrusion plate 21 to press on the inner wall of the empty groove 23 through the connecting rod 22, thereby increasing the friction between the extrusion plate 21 and the empty groove 23, thereby positioning the position of the movable block 24 and improving stability.

[0027] A sliding frame 12 is provided inside the accommodating chamber 4, and sliding blocks 5 are fixed to one end of the upper and lower ends of the sliding frame 12, and sliding grooves 6 are provided at both upper and lower ends of the accommodating chamber 4, and the sliding frame 12 is slidably connected to the accommodating chamber 4 through the cooperation of the sliding blocks 5 and the sliding grooves 6;

[0028] The sliding frame 12 is L-shaped, and guide grooves 9 are provided at both upper and lower ends of the sliding frame 12. Rotation grooves 7 are provided at one end of both upper and lower ends of the sliding frame 12, and the rotation grooves 7 are connected to one side of the guide grooves 9. Fixed blocks 8 are fixed to one end of the upper and lower ends of the placement plate 2, and one end of the two fixed blocks 8 extends to the inner walls of the two guide grooves 9 respectively.

[0029] The fixed block 8 and the guide groove 9 form a sliding fit, and the fixed block 8 and the rotating groove 7 form a rotation fit;

[0030] Specifically, Figure 1 , Figure 2 and Figure 3As shown, when a circuit board needs to be taken, the rotating rod 3 on the corresponding placement plate 2 can be used to pull the placement plate 2. The fixed block 8 on the outside of the placement plate 2 continues to slide inside the guide groove 9 and finally enters the inside of the rotation groove 7. At this time, the rotating rod 3 is continued to be pulled, and the placement plate 2 applies force to the rotation groove 7 through the fixed block 8, causing the sliding frame 12 to be also pulled by force, and is pulled out partially with the help of the cooperation of the sliding block 5 and the sliding groove 6. At this time, the placement plate 2 is rotated with the help of the cooperation of the fixed block 8 and the rotation groove 7, so that the circuit board placed on the placement plate 2 is directly exposed to the user, which is convenient for the user to take. When taking it, the rubber cover 19 is completely removed and then the circuit board is removed.
