The magnetic attraction member 315 is disposed at one end of the movable column 314, and a first elastic member 313 is disposed between the movable column 314 and the substrate 311, where the first elastic member 313 drives the movable column 314 to move toward a first direction (i.e. the first direction is the X direction in fig. 4). During installation, the movable column 314 pushes the buckle 312 to move towards the clamping piece 32, so that the buckle 312 abuts against the clamping piece 32. When the maintenance is detached, the external magnetic tool 4 is close to the magnetic part 315, the magnetic pole direction of the external magnetic tool 4 is opposite to the magnetic pole of the magnetic part 315, and under the action of the magnetic force of the mutual attraction, the magnetic part 315 moves towards the second direction (the second direction is the Y direction in FIG. 4) against the elastic force of the first elastic part 313, so that the buckle 312 is separated from the clamping part 32, and the first direction is opposite to the second direction.

Specifically, the first side 3111 may be provided with one, two or more buckles 312, in this embodiment, for example, two buckles 312 are symmetrically disposed on two sides of the movable column 314, as shown in fig. 6, a pushing portion 3122 is disposed on a side of the buckle 312 adjacent to the movable column 314, the pushing portion 3122 is provided with an inclined guiding surface 31221, and the guiding surface 31221 is inclined from an end far from the substrate 311 toward an end near the substrate 311 and toward the center of the movable column 314. As shown in fig. 4, the movable column 314 includes a column body and a pushing portion 316 disposed at one end of the column body, the cross-sectional dimension of the column body along the direction perpendicular to the movement direction of the movable column 314 is smaller than the cross-sectional dimension of the pushing portion 316 along the direction perpendicular to the movement direction of the movable column 314, the column body moves closer to or farther from the engaging member 32 along the axial direction of the movable column 314, and the pushing portion 316 abuts against the guide surface 31221. The first elastic member 313 is a first spring, when the column body is located at the initial position (as shown in fig. 5), the first spring drives the column body to drive in the X direction, so that the pushing portion 316 moves in the X direction along the guiding surface 31221, and the buckles 312 on both sides open in the direction away from each other, so that sufficient clamping force is given to the buckles 312 to be clamped with the clamping members 32, so that the buckles 312 are firmly clamped with the clamping members 32, the connection is stable, and the lamp panel assembly 2 can be prevented from falling off from the box 1; when the maintenance is dismantled, the outside magnetism is inhaled instrument 4 and is the magnet with magnetism inhale piece 315 looks attraction, utilize outside magnetism to inhale instrument 4 and magnetism inhale the magnetism between the piece 315 and inhale the piece and drive magnetism inhale the piece 315, make magnetism inhale the piece 315 overcome the first spring and pull the power that the post body moved to the X direction and move to the Y direction, thereby make the pushing part 316 follow guide surface 31221 and move to the Y direction, make the buckle 312 of both sides move to the direction that is close to each other gradually, thereby make buckle 312 can not support tightly with joint piece 32, buckle 312 and joint piece 32 separation promptly, utilize less external force can directly pull apart lamp plate subassembly 2, dismantle maintenance convenient and fast, labour saving and time saving.

Alternatively, as shown in fig. 4, a pushing surface 3161 corresponding to the inclination angle of the guiding surface 31221 is disposed on the side of the pushing portion 316 close to the guiding surface 31221, so as to increase the contact area between the pushing portion 316 and the pushing portion 3122, and make the sliding fit between the pushing portion 316 and the pushing portion 3122 more stable.

The above design can make the movable column 314 move stably along the vertical direction (i.e. the X direction and the Y direction), so that the contact between the pushing portion 316 and the pushing portions 3122 is more precise, and the connection between the latch hook 3121 and the clip 32 is further stable. Alternatively, the substrate 311 is thinner, so that the depth of the first hole 3112 is shallower, when the length of the movable column 314 is longer, the movable column 314 is driven by the first elastic member 313 to move inevitably to swing, so a guiding portion 318 may be further protruding from the first side surface 3111 of the substrate 311 along the periphery of the first through hole 3112, and the inner side wall of the guiding portion 318 is slidably connected with the movable column 314, so that compared with the guiding of the wall of the first hole 3112 on the movable column 314, the guiding of the inner side wall of the guiding portion 318 on the movable column 314 is increased, the guiding distance of the whole movable column 314 is lengthened, and the movable column 314 is ensured to move stably driven by the first elastic member 313.

Alternatively, the first spring may be connected to the second side 3113 and the stop 317 by abutting, or may be connected by a fixed connection (e.g., welding, screw fixing, etc.). When the first spring is connected to the second side surface 3113 and the stopper 317 by abutting, the first spring can be easily removed and replaced. In addition, the stop portion 317 is limited during disassembly, so that the magnet can be effectively prevented from excessively pulling the magnetic attraction member 315 to cause failure of the first spring, the reusability of the first spring is ensured, and the column body is effectively prevented from being separated from the first through hole 3112.
