When the bottom plate, middle plate and top plate need to be disassembled to take out the circuit board, the pull rod is pulled to drive the wedge-shaped locking rod to disengage from the card slot to release the limiting fixation of the wedge-shaped rod. At this time, the wedge-shaped rod is pulled out of the slot under the reset of the No. 2 spring on the wedge-shaped rod, so that the top plate and middle plate can be disassembled to take out the circuit board.

[0023] By setting up the moving device 5, when the circuit board is placed on the top of the base plate 1 and the device needs to be moved to another position, the motor on the top of the threaded rod 8 can be started to drive the threaded rod 8 to rotate and push the roller rod 7 out from the bottom of the moving device 5. When the roller at the bottom of the moving device 5 contacts the ground and the support rod 6 is lifted off the ground, the circuit board on the base plate 1 can be pushed to the required position. After the device is moved into place, the motor on the threaded rod 8 is started to drive the threaded rod 8 to rotate in the reverse direction, and the roller rod 7 is retracted so that the anti-slip pad at the bottom of the support rod 6 contacts the ground.

[0024] Reference Figure 1 , 3, wedge-shaped rods 10 are slidably installed on both sides of the inner part of the middle plate 2 and the top plate 3, and a second slide groove adapted to the wedge-shaped rod 10 is opened in the middle plate 2 and the top plate 3, and a second spring is installed on the outer wall of the wedge-shaped rod 10, and a toggle block 11 is fixedly installed on the top of the wedge-shaped rod 10, and the toggle block 11 is slidably installed on the outer wall of the middle plate 2 and the top plate 3, and slots 12 adapted to the wedge-shaped rod 10 are opened on both sides of the top of the bottom plate 1 and the middle plate 2, and the inside of the bottom plate 1 and the middle plate 2 is located at the insert A wedge-shaped locking rod 13 is slidably installed on the outer side of the groove 12, and a No. 3 sliding groove compatible with the wedge-shaped locking rod 13 is opened inside the bottom plate 1 and the middle plate 2, and a No. 3 spring is fixedly installed on the outer end of the wedge-shaped locking rod 13, and a slot 14 compatible with the wedge-shaped locking rod 13 is opened on the outer side of the wedge-shaped insertion rod 10.

[0025] By providing the wedge-shaped insert rod 10 and the wedge-shaped locking rod 13, when the circuit board is placed on the bottom plate 1, the middle plate 2 can be specifically equipped according to the number of circuit boards. When there are fewer circuit boards, the top plate 3 can be directly covered on the top of the bottom plate 1. When the number of circuit boards is large, multiple groups of middle plates 2 can be arranged to be stacked on the bottom plate 1 to store the circuit boards, and finally the top plate 3 can be covered on the top of the uppermost middle plate 2. When the bottom plate 1, the middle plate 2, and the top plate 3 are covered with each other in sequence, the toggle block 11 is pushed downward to drive the wedge-shaped insert rod 10 to be inserted into the slot 12. Since the ends of the wedge-shaped insert rod 10 and the wedge-shaped locking rod 13 are both inclined, the wedge-shaped insert rod 10 will squeeze the wedge-shaped locking rod 13 to move outward. The wedge-shaped rod 10 is moved out of position until it is inserted into place, and the wedge-shaped locking rod 13 encounters the slot 14 and is inserted into the slot 14 under the rebound of the No. 3 spring to lock the wedge-shaped rod 10, thereby ensuring a stable assembly between the bottom plate 1, the middle plate 2, and the top plate 3 to prevent the circuit board from falling due to vibration during transportation. When it is necessary to disassemble the bottom plate 1, the middle plate 2, and the top plate 3 to take out the circuit board, the pull rod 15 is pulled to drive the wedge-shaped locking rod 13 to disengage from the slot 14 to release the limiting fixation of the wedge-shaped rod 10. At this time, the wedge-shaped rod 10 is pulled out of the slot 12 under the reset of the No. 2 spring on the wedge-shaped rod 10, and the top plate 3 and the middle plate 2 can be disassembled to take out the circuit board.

[0026] The implementation principle of the embodiment of the utility model is:

[0027] First, the function of the mobile device 5 is explained. When the circuit board is placed on the top of the base plate 1 and the device needs to be moved to another position, the motor on the top of the threaded rod 8 can be started to drive the threaded rod 8 to rotate and push the roller rod 7 out from the bottom of the mobile device 5. When the roller at the bottom of the mobile device 5 contacts the ground and the support rod 6 is lifted off the ground, the circuit board on the base plate 1 can be pushed to the required position. After the device is moved into place, the motor on the threaded rod 8 is started to drive the threaded rod 8 to rotate in the reverse direction, and the roller rod 7 is retracted so that the anti-slip pad at the bottom of the support rod 6 contacts the ground.

[0028] After the circuit boards are placed on the bottom plate 1, the middle plate 2 can be specifically installed according to the number of circuit boards. When there are fewer circuit boards, the top plate 3 can be directly covered on the top of the bottom plate 1. When the number of circuit boards is large, multiple groups of middle plates 2 can be set to be stacked on the bottom plate 1 to store the circuit boards, and finally the top plate 3 can be covered on the top of the uppermost middle plate 2. When the bottom plate 1, the middle plate 2, and the top plate 3 are covered with each other in sequence, the toggle block 11 is pushed downward to drive the wedge-shaped rod 10 to be inserted into the slot 12. Since the ends of the wedge-shaped rod 10 and the wedge-shaped locking rod 13 are both inclined, the wedge-shaped rod 10 will squeeze the wedge-shaped locking rod 13 to move outward to make way until the wedge-shaped rod 10 is When the rod 10 is inserted into place, the wedge-shaped locking rod 13 encounters the slot 14 and is inserted into the slot 14 under the rebound of the No. 3 spring to lock the wedge-shaped rod 10, thereby ensuring a firm assembly between the bottom plate 1, the middle plate 2, and the top plate 3 to prevent the circuit board from falling due to vibration during transportation. When it is necessary to disassemble the bottom plate 1, the middle plate 2, and the top plate 3 to take out the circuit board, pull the pull rod 15 to drive the wedge-shaped locking rod 13 to disengage from the slot 14 to release the limiting fixation of the wedge-shaped rod 10. At this time, the wedge-shaped rod 10 is pulled out of the slot 12 under the reset of the No. 2 spring on the wedge-shaped rod 10, so that the top plate 3 and the middle plate 2 can be disassembled to take out the circuit board.

[0029] The above technical solutions are only preferred embodiments of the present utility model, and certainly cannot be used to limit the scope of rights of the present utility model. Therefore, equivalent changes made within the scope of the patent of the present utility model still fall within the protection scope of the present utility model.
