When it is needed to dismount the board card 10, the connecting rod 17 is rotated to switch the locking piece 18 from the locking position to the unlocking position, the locking piece 18 is separated from the locking slot 110, the abutting force between the locking piece 18 and the inner wall of the locking slot 110 disappears, and the placing box 14 can move relative to the workbench 1 along the first direction to make the end of the placing box 14 installed with the board card 10 extend out of the workbench 1, facilitating the dismounting of the board card 10.

[0045] By rotating the connecting rod 17 to switch the locking piece 18 to the locking position, the locking piece 18 can be kept in the locking slot 110 by the first elastic piece 15, so that the placing box 14 can be fixed relative to the workbench 1 to facilitate the test of the board card 10; and after the test is completed, the locking piece 18 is switched to the unlocking position by rotating the connecting rod 17, so that the placing box 14 can be moved along the first direction to make the end of the placing box 14 installed with the board card 10 extend out of the workbench 1, facilitating the dismounting of the board card 10.

[0046] Further, as shown in Figure 2 the workbench 1 is provided with a guide sliding groove 12 that is slidably matched with the placing box 14 along the first direction, and the guide sliding groove 12 is open at one end in the first direction to form an assembly opening for the placing box 14 to enter and exit the guide sliding groove 12. Specifically, the first direction is a first horizontal direction, the workbench 1 is provided with a mounting slot 11 extending along the first horizontal direction, the placing box 14 is placed in the mounting slot 11, the placing box 14 is provided with sliding grooves on the opposite two side walls in a second horizontal direction, and the placing box 14 is provided with sliding blocks 13 on the opposite two sides in the second horizontal direction. The placing box 14 is supported by the inner wall of the guide sliding groove 12, and the two sliding blocks 13 are slidably matched with the two sliding grooves along the first horizontal direction, so that the end of the placing box 14 installed with the board card 10 can enter and exit the assembly opening along the first direction, and the installation is smooth. It should be noted that the first horizontal direction and the second horizontal direction are perpendicular.

[0047] During the test, the placing box 14 is completely placed in the guide sliding groove 12; when it is needed to replace the board card 10 after the test, the placing box 14 is slid along the first direction to make the end of the placing box 14 close to the assembly opening extend out of the guide sliding groove 12, facilitating the replacement of the board card 10.

[0048] Further, the first elastic member 15 is arranged between the placement box 14 and the inner wall of the guide chute 12 away from the assembly opening in the first direction; the connecting rod 17 is rotatably connected to the workbench 1 through the pin shaft 16, and the first elastic member 15 and the pin shaft 16 are located on the same side of the placement box 14 in the first direction.

When the connecting rod 17 is rotated to switch the locking member 18 from the unlocked position to the locked position, the placement box 14 is compressed in the first direction, and the first elastic member 15 has elastic potential energy after being compressed. The elastic force of the first elastic member 15 in the first direction will make the placement box 14 have a tendency to move to the side where the assembly opening is located, and the inner wall of the locking slot 110 will abut against the locking member 18, so that the locking member 18 is kept in the locking slot 110, thereby fixing the placement box 14 relative to the workbench 1, facilitating the testing of the board card 10.

[0050] In other embodiments, the first elastic member 15 can also have one end abutting against the locking member 18 and the other end connected to the workbench 1. In other embodiments, the first elastic member 15 can also be a tension spring or a torsion spring, as long as the first elastic member 15 exerts a force on the placement box 14 or the locking member 18 to make the locking member 18 abut against the inner wall of the locking slot 110 in the first direction, so that the locking member 18 cannot escape from the locking slot 110.

[0051] Further, the placement box 14 is provided with a guide slot 19, one end of the guide slot 19 communicates with the locking slot 110, and the other end is located between the locking slot 110 and one end of the connecting rod 17 connected to the workbench 1; the connecting rod 17 can rotate to make the locking member 18 reciprocate between the locking slot 110 and the guide slot 19; when the locking member 18 is in the unlocked position, the locking member 18 is slidably arranged in the guide slot 19.

[0052] Push the placement box 14 to the side close to the first elastic member 15 in the first direction, so that the locking member 18 is aligned with the communication position of the locking slot 110 and the guide slot 19, then control the connecting rod 17 to rotate around the pin shaft 16, the connecting rod 17 drives the locking member 18 to enter the guide slot 19 from the locking slot 110; then remove the external force acting on the placement box 14, because the abutting force between the locking member 18 and the inner wall of the locking slot 110 disappears, the first elastic member 15 will push the placement box 14 to move relative to the workbench 1 in the first direction to make the end of the placement box 14 close to the assembly opening protrude from the guide chute 12, realizing the automatic ejection of the placement box 14, facilitating the installation or removal of the board card 10 in the placement box 14 by the staff; in this process, the locking member 18 slides in the guide slot 19 and gradually moves away from the locking slot 110.

[0053] After the board card 10 is installed in the placing box 14, the placing box 14 is pushed towards the side close to the first elastic member 15 along the first direction, the locking member 18 slides in the guide slot 19 and gradually approaches the locking slot 110, so that the locking member 18 is aligned with the communication position of the locking slot 110 and the guide slot 19; then the control link 17 is rotated around the pin shaft 16, the control link 17 drives the locking member 18 to enter the locking slot 110 from the guide slot 19, in this process, the first elastic member 15 is constantly compressed, then the external force applied to the placing box 14 is removed, the first elastic member 15 applies a force to the placing box 14, so that the placing box 14 has a tendency to move towards the side close to the assembly opening along the first direction, the inner wall of the locking slot 110 abuts against the locking member 18, so that the locking member 18 is kept in the locking slot 110, thereby limiting the movement of the placing box 14 relative to the workbench 1 along the first direction, facilitating the testing of the board card 10 in the placing box 14.

[0054] In other embodiments, the control link 17 can also be hinged with the workbench 1, so that the other end of the control link 17 can be rotated to the upper side of the placing box 14 to be separated from the locking slot 110. When it is needed to switch the locking member 18 from the locking position to the unlocking position, the control link 17 is rotated to lift the locking member 18 upwards, driving the locking member 18 to be separated from the locking slot 110, the abutting force between the locking member 18 and the inner wall of the locking slot 110 disappears, under the elastic force of the first elastic member 15, the placing box 14 will move relative to the workbench 1 along the first direction to make the end of the placing box 14 installed with the board card 10 to extend out of the workbench 1. When it is needed to switch the locking member 18 from the unlocking position to the locking position, the placing box 14 is pushed towards the side close to the first elastic member 15 along the first direction, so that the locking member 18 is located directly above the locking slot 110, the control link 17 is controlled to rotate to make the locking member 18 fall into the locking slot 110, then the force applied to the placing box 14 is removed, the first elastic member 15 will keep the locking member 18 in the locking slot 110.

[0055] Exemplarily, the guide slot 19 includes a first V-shaped slot and a second V-shaped slot oppositely arranged along the first direction, the second V-shaped slot is closer to the assembly opening along the first direction than the first V-shaped slot; the locking slot 110 is arranged at the corner of the second V-shaped slot and the inner wall of the corner close to the first V-shaped slot, the locking slot 110 is an arc-shaped slot and the opening of the arc-shaped slot faces away from the pin shaft 16 along the first direction.

[0056] As Figure 1 , 2As shown, when the locking piece 18 is in the locking position, the locking piece 18 is in the arc-shaped slot and abuts against the inner wall of the arc-shaped slot, the inner wall of the arc-shaped slot has a certain limiting effect on the locking piece 18, which ensures that the locking piece 18 will not come off the locking slot 110 when it is in the locking position, thereby improving the locking stability. When the locking piece 18 is switched from the locking position to the unlocking position, the placement box 14 is pushed by an external force to move in the direction of compressing the first elastic piece 15, so that the locking piece 18 is separated from the inner wall of the arc-shaped slot close to the first elastic piece 15, and then the connecting rod 17 is rotated, the connecting rod 17 drives the locking piece 18 to enter the second V-shaped slot from the arc-shaped slot, and under the elastic force of the first elastic piece 15, the connecting rod 17 drives the locking piece 18 to enter the first V-shaped slot along the second V-shaped slot, when the locking piece 18 slides to the corner of the first V-shaped slot, one end of the placement box 14 mounting plate card 10 can extend out of the workbench 1, which is convenient for the staff to disassemble and assemble the plate card 10.

[0057] In other embodiments, the guide slot 19 can also be provided as a V-shaped slot or an arc-shaped slot opening towards the second direction, and the first direction and the second direction are both horizontal directions and perpendicular. In other embodiments, the guide slot 19 can also be provided as an L-shaped slot, the L-shaped slot includes a first slot and a second slot, the first slot extends along the first horizontal direction, and the second slot extends along the second horizontal direction, and the second slot is slotted along the inner wall of the first horizontal direction close to the first elastic piece 15 to form the guide slot 19.

[0058] Further, the placement box 14 has a mounting channel extending along the first direction for mounting the plate card 10, the mounting channel is provided with a connecting slot 2 facing at least one inner wall of the plate card 10 along the thickness direction of the plate card 10, and the thickness direction of the plate card 10 is perpendicular to the first direction; the plate card mounting structure further includes a pressing piece 23 and a second elastic piece 22, the pressing piece 23 is movably provided in the connecting slot 2 along the thickness direction of the plate card 10, and the second elastic piece 22 is used to apply a force along the thickness direction of the plate card 10 to the pressing piece 23, so that the pressing piece 23 abuts against one side of the plate card 10 in the thickness direction.

[0059] Insert the plate card 10 into the mounting channel along the first direction, the second elastic piece 22 applies a force along the thickness direction of the plate card 10 to the pressing piece 23, so that the pressing piece 23 presses the plate card 10 tightly, ensuring that the plate card 10 is stably mounted in the placement box 14.

[0060] As shown in Figure 1 , 3 The inner bottom wall of the placement box 14 is provided with a plurality of connecting slots 2 arranged at intervals along the second direction, and the plate card mounting structure further includes a guide piece 21, the guide piece 21 is provided in the connecting slot 2 and one end is connected to the inner wall of the connecting slot 2, the second elastic piece 22 is sleeved outside the guide piece 21, one end of the second elastic piece 22 is connected to or abuts against the inner wall of the connecting slot 2, and the other end is connected to the pressing piece 23.

[0061] Specifically, the extruder 23 abuts against the side of the plate 10 in the thickness direction, i.e., the upper surface of the extruder 23 is the first surface. The side of the extruder facing away from the first elastic member 15 in the first horizontal direction forms a second surface. The first surface and the second surface are connected by a guide surface. Along the first horizontal direction close to the first elastic member 15, the guide surface gradually approaches the first surface from bottom to top. For example, the guide surface is a chamfered surface. As an alternative, the guide surface can also be a rounded chamfered surface.

[0062] For example, the second elastic element 22 is a compression spring. When the plate 10 is inserted into the mounting channel along the first direction, the plate 10 will enter the space between the extruder 23 and the inner top wall of the mounting channel under the guidance of the guide surface, and will generate a downward component force under the action of the guide surface, so that the plate 10 applies a downward force to the extruder 23. Under the force, the extruder 23 compresses the second elastic element 22 along the axial direction of the guide 21. The guide 21 can prevent the second elastic element 22 from shifting during the compression process. After being compressed, the second elastic element 22 has elastic potential energy and needs to be reset, pushing the extruder 23 to press the first surface against the plate 10, so that the plate 10 can be stably installed in the placement box 14.

[0063] Preferably, the guide member 21 is a telescopic rod, with one end connected to the inner wall of the connecting groove 2 and the other end connected to the extruder 23.
