[0040] It should be noted that the boss 320 is an integrally formed structure, including the second bump 322, the column 323 and the first bump 321 distributed from top to bottom. The integrally formed boss 320 is beneficial to production and installation. The column 323 is a cylindrical structure, the second bump 322 is integrally formed on the upper side of the column 323, the rotating block 310 and the second bump 322 are both located on the upper side of the column 323, and the rotating block 310 and the second bump 322 can pass through the first through hole of the lower front plate 100, so as to jointly position the lower front plate 100. The rotating block 310 abuts against the second bump 322, and the second bump 322 provides a limit for the rotation of the rotating block 310.

[0041] In addition, in an embodiment, with reference to Figures 1 to 3 , the rotating block 310 includes a first side surface 311 and a second side surface 312.

[0042] It should be noted that in the state where the rotating block 310 does not abut against the second panel 120, the first side surface 311 of the rotating block 310 abuts against the second bump 322, and the rotating block 310 and the second bump 322 jointly position the lower front plate 100. The lower front plate 100 is placed on the bracket body 200, the lower front plate 100 abuts against the trigger device 400, and the trigger device 400 drives the transmission structure 340 through the driving structure, so that the rotating block 310 rotates counterclockwise, so that the rotating block 310 abuts against the second panel 120, and the second side surface 312 of the rotating block 310 abuts against the second bump 322. During the rotation of the rotating block 310, the second bump 322 plays a limiting role in the rotation of the rotating block 310.

[0044] It should be noted that the driving device is connected to the rotating block 310 through the transmission structure 340. After the driving device receives an electrical signal, the driving device drives the transmission structure 340 to work, thereby driving the rotating block 310 to rotate. One end of the second transmission block 342 is connected to the rotating block 310 through a connecting member, and the connecting member enables the rotating block 310 and the second transmission block 342 to rotate in the same direction. When the driving device works, the driving rod 343 moves backward, the first transmission block 341 rotates clockwise, and the second transmission block 342 rotates counterclockwise, thereby driving the rotating block 310 to rotate counterclockwise to the upper side of the second panel 120, and the lower front plate 100 is fixed by pressing the second panel 120 through the rotating block 310.

[0045] In addition, in one embodiment, referring to Figure 1 and Figure 2 , the lower front plate 100 includes at least two first through holes, the number of components 300 is at least two, and the number of components 300 is less than or equal to the number of first through holes.

[0046] It should be noted that the lower front plate 100 includes at least two first through holes, and the number of components 300 being at least two is to prevent the lower front plate 100 from moving and rotating, thereby better fixing the lower front plate 100. Referring to Figure 2 , when the lower front plate 100 is provided with three first through holes distributed linearly, the number of components 300 is two, and the two components 300 are respectively arranged at the first and the third of the three linearly distributed first through holes. This setting method makes the force on the lower front plate 100 balanced, thereby achieving a better fixing effect of the lower front plate 100.

[0047] In addition, in one embodiment, referring to Figure 2 and Figure 4 , it further includes a cross bar 500. The cross bar 500 is connected to the driving device, and the cross bar 500 is fixedly connected to the driving rods 343 of each component 300.
