As shown in Figures 4 and 5, the above-mentioned second fixing bolt 6 includes a bolt sleeve 21, a second spring 22, and a screw rod 23, wherein one end of the screw rod 23 is slidably installed on the inner side of the bolt sleeve 21 through the cooperation of the guide block and the guide groove, and a second spring 22 is installed between the screw rod 23 and the bolt sleeve 21; when fixing the fixing plate 32, the first expansion bolt sleeve 24 is driven into the wall surface, and the first expansion bolt sleeve 24 has a conical surface 25 for easy driving into the wall surface, and has two stepped circular holes of different sizes on the inside, the bolt sleeve 21 is gap-nested with the large circular hole on the outside, and the screw rod 23 is threadedly engaged with the small circular hole on the inside.

The second fixing bolt 6 designed in the present invention has a buffering effect during use through the designed screw rod 23 and the second spring 22. During the use of the equipment, since the first fixing bolt 4 on the upper side has no buffering effect, the upper side of the equipment will fall off the wall surface before the lower side is fixed with the second fixing bolt 6. The first fixing bolt 4 and the second expansion bolt sleeve 26 in the present invention are prior art, and the matching principle of the screw rod 23 and the first expansion bolt sleeve 24 in the second fixing bolt 6 is the same as the working principle of the existing expansion bolt.

Specific working process: when using the mounting bracket designed by the present invention, firstly, a bolt fixing hole is punched on the wall, and then the telescopic fixing mechanism 5 is pulled open to fix the telescopic fixing mechanism 5 on the wall. The end of the trigger rod 47 close to the wall will be squeezed by the wall and flush with the second telescopic inner plate 27, and the sixth spring 43 is stretched; the limiting mechanism 9 is located on the side away from the telescopic fixing mechanism 5; at this time, the first telescopic outer sleeve 8 and the first telescopic inner plate 55 in the telescopic support mechanism 3 are manually stretched. During the stretching process, the first telescopic inner plate 55 will squeeze the limit block 41 through the inclined surface on the limit block 41, so that the limit block 41 moves to the inside of the limit shell 39, and the fifth spring 42 is compressed. When the first telescopic inner plate After 55 passes over the limit block 41 in the limit mechanism 9, under the action of the fifth spring 42, the limit block 41 extends out of the limit housing 39 to limit the first telescopic inner plate 55. At this time, the upper end of the first telescopic inner plate 55 is also inserted into the upper sliding sleeve 36; then install the wires. When installing the wires, manually rotate the telescopic threaded rod 45 so that the end of the telescopic threaded rod 45 hinged to the dial plate 11 drives the dial plate 11 to swing. The swing of the dial plate 11 drives the dial rod 10 to swing through the dial groove 46, thereby releasing the lock of the swing plate 14 in the three wire fixing modules 1. At this time, the swing plate 14 can be manually opened, the wires can be put in, and then the telescopic threaded rod 45 can be rotated to reset the lock plate 17 to fix the wires.

In the engineering use, when the upper first fixing bolt 4 falls off from the wall, at the beginning of the falling off, due to the existence of the sliding sleeve 36 and the oblique distribution of the first telescopic inner plate 55 and the first telescopic outer sleeve 8, the second telescopic inner plate 27 and the second telescopic outer sleeve 31 will be stuck and will not shrink. When the first fixing bolt 4 completely falls off from the wall, the second telescopic inner plate 27 and the second telescopic outer sleeve 31 will swing downward relative to the fixing plate 32, so that the trigger rod 47 is separated from the wall. At this time, under the action of the sixth spring 43, the trigger rod 47 slides toward the side of the second telescopic inner plate 27. The sliding of the trigger rod 47 drives the second swing rod 40 to swing, and the swing of the second swing rod 40 drives the limiting mechanism 9 to slide in the guide sliding sleeve 38 to release the limitation of the first telescopic inner plate 55 and the first telescopic outer sleeve 8; on the other hand, the sliding of the trigger rod 47 will drive the dial plate 11 to swing through the connecting ear 44 and the telescopic threaded rod 45, thereby releasing the swing plate 14 in the three wire fixing modules 1. Limiting; after the limiting mechanism 9 releases the limiting of the first telescopic inner plate 55 and the first telescopic outer sleeve 8, the first telescopic inner plate 55 and the second telescopic outer sleeve 31 will slide downward relative to the first telescopic outer sleeve 8 and the second telescopic inner plate 27, as shown in Figure 9, the sliding of the first telescopic inner plate 55 drives the upper wire fixing module 1 to move downward, preventing the second telescopic inner plate 27 and the second telescopic outer sleeve 31 from driving the first telescopic inner plate 55, the first telescopic outer sleeve 8 and the three wire fixing modules 1 to swing downward, and the wire fixing module 1 located on the upper side will hit the middle wire and affect the wire; in the process where the second telescopic inner plate 27 and the second telescopic outer sleeve 31 drive the first telescopic inner plate 55, the first telescopic outer sleeve 8 and the three wire fixing modules 1 to swing downward, the three wires will squeeze the three swinging plates 14 in the three wire fixing modules 1 to open, and the three wire fixing modules 1 will be detached from the three wires, preventing the mounting frame from applying pressure to the wires after being detached from the wall, affecting the work of the wires.
