The implementation principle of the embodiment is as follows: when the components on the back side of the LED lamp panels 14 are damaged, since all the LED lamp panels 14 are in the same plane and the outer peripheries of the adjacent LED lamp panels 14 are abutted, there is no proper point of application for an operator to pull out the unit frame 2. Therefore, the operator can press the LED lamp panel 14 first to move the second pushing block 42 to push the valve block 48, and the valve rod 491 is inserted into the insertion hole 481, so that the valve block 48 cannot be reset, and the first pushing block 43 can slide from the side of the valve block 48 away from the unit frame 2 to the side of the valve block 48 close to the unit frame 2. Furthermore, the block unit frame 2 can protrude from the other unit frames 2 by the elastic force of the first elastic member 44, and a force application point for an operator to pull out the unit frame 2 is generated.
At this time, the operator can pull the unit frame 2 outward to the extreme position to create a sufficient maintenance space for the operator to repair or replace the component.
When the operator pulls the unit frame 2 out to the limit position, the reset circuit 5 can energize the electromagnet 493, and the electromagnet 493 attracts the valve stem 491, so that the valve stem 491 is separated from the insertion hole 481, and the valve block 48 is reset to the original position by the elastic force of the second elastic member 47. When the operator returns to the unit frame 2, the first pushing block 43 first abuts against the guiding inclined surface 482, and drives the valve block 48 to move in a short distance in a direction away from the fixing bar 41, that is, the insertion hole 481 cannot reach the locking hole 49; finally, the first pushing block 43 moves to the side of the valve block 48 far away from the unit frame 2 and abuts against the side of the valve block 48, and the operator stops pushing, so that the unit frame 2 is reset.
When the unit frame 2 moves outward to the limit position, the sub-slider 34 moves to the lowest end of the unit sliding slot 321, and the elastic protrusion 322 is stopped at the upper side of the sub-slider 34, so that the unit frame 2 can keep the state of extending outward to the limit position. When the operator wants to retract the unit frame 2, the operator only needs to press the unit frame 2 so that the unit frame 2 is close to the mounting frame 1, and the sub-slider 34 slides over the elastic protrusion 322 and slides to the upper side of the elastic protrusion 322.
Example two: referring to fig. 10 and 11, the second embodiment differs from the first embodiment only in that: instead of the electromagnet 493 and the reset circuit 5, a pull rope 494 is provided, one end of the pull rope 494 is connected to the end of the valve stem 491, and the other end thereof penetrates through the connecting rod 13.

The implementation principle of the embodiment is as follows: the first embodiment is substantially the same, except for the operation of releasing the end of the stem 491 from the insertion hole 481, which is as follows:
when the unit frame 2 moves outward to the limit position, the take-up pulley 23 has completely paid out all the taken-up draw strings 494, and the draw strings 494 just pull the valve stem 491 so that the end of the valve stem 491 is released from the insertion hole 481. When an operator presses the LED lamp panel 14, the unit frame 2 is reset to the side where the installation frame 1 is installed, the pull rope 494 is continuously wound on the periphery of the take-up pulley 23 until the LED lamp panel 14 and the adjacent LED lamp panel 14 are level, and the take-up pulley 23 finishes winding up.
