[0028] When using this device, first install the connecting component 3 in the installation cavity 15 on the vertical frame 11, and fix the connecting component 3 to the vertical frame 11 by the fixing bolts 13. After fixing, take out the transverse frame 12, align the transverse frame 12 vertically with the vertical frame 11, insert the bottom of the connecting component 3 into the installation cavity 15 on the transverse frame 12, use the fixing bolts 13 to fix the transverse frame 12 and the connecting component 3, and fix the vertical frame 11 and the transverse frame 12 through the connecting component 3. After fixing, place the L-shaped reinforcement plate 18 in the fixing groove 14 on the vertical frame 11 and the transverse frame 12, fix the screws on the L-shaped reinforcement plate 18, and further fix the vertical frame 11 and the transverse frame 12 through the L-shaped reinforcement plate 18.

[0029] For example 2, please refer to Figure 1-6The auxiliary fixing assembly 2 includes a return spring 21 and a connecting rod 22. The return spring 21 is sleeved on the connecting rod 22. One end of the return spring 21 is fixed to the inner wall of the connecting groove 17, and the other end is fixed to one end of the connecting rod 22. The other end of the connecting rod 22 passes through the connecting groove 17 and extends into the mounting cavity 15. The extended end of the connecting rod 22 is fixedly connected with a clamping block 23. The connecting assembly 3 includes a first connecting block 31. An auxiliary reinforcing block 34 is installed on the top of the first connecting block 31. Both sides of the auxiliary reinforcing block 34 are provided with a clamping groove 35. The two ends of the clamping groove 35 are respectively clamped in the mounting cavity 15 on the vertical frame 11 and the horizontal frame 12. The two clamping grooves 35 are respectively clamped with adjacent clamping blocks 23. Fixed blocks 32 are installed on both sides near the top of the first connecting block 31. The two fixed blocks 32 slide respectively on In the two sliding grooves 16 on the vertical frame 11, a plurality of first mounting holes 33 connected to the fixing bolts 13 are further provided on both sides of the first connecting block 31, and limiting grooves 38 are further provided on both sides of the first connecting block 31 near the bottom end. The pushing component 4 is slidably connected in the limiting groove 38, and a second connecting block 36 for connecting to the transverse frame 12 is further slidably connected on one side of the first connecting block 31. Second mounting holes 37 connected to the fixing bolts 13 on the transverse frame 12 are provided on both sides of the second connecting block 36. The pushing component 4 includes two sliding blocks 41, and the two sliding blocks 41 are respectively slidably connected to adjacent limiting grooves 38. An extrusion block 42 is installed between the two sliding blocks 41, and the side of the extrusion block 42 close to the second connecting block 36 is set as a bevel, and the bevel of the extrusion block 42 contacts the second connecting block 36;

[0030] When in use, first insert the end of the first connecting block 31 provided with the auxiliary reinforcement block 34 into the installation cavity 15 on the vertical frame 11, and at the same time align the fixing block 32 with the sliding groove 16, so that the fixing block 32 slides upward along the sliding groove 16. When the first connecting block 31 is inserted, the top of the auxiliary reinforcement block 34 pushes the clamping block 23. Under the action of the auxiliary reinforcement block 34, the two clamping blocks 23 drive the connecting rod 22 to retract into the connecting groove 17, and at the same time squeeze the return spring 21, causing the return spring 21 to contract and accumulate force.

[0031] After the first connecting block 31 is continuously inserted, the auxiliary reinforcing block 34 continuously moves upward. When the engaging groove 35 moves to the engaging block 23, the engaging block 23 is no longer pushed by the auxiliary reinforcing block 34. Under the action of the rebound force of the return spring 21, the connecting rod 22 and the engaging block 23 are driven to pop outward, so that the engaging block 23 is engaged with the engaging groove 35. The engaging groove 35 is fixed by the engaging block 23, so that the first connecting block 31 is initially fixed in the installation cavity 15.

[0032] After fixing, screw the fixing bolt 13 through the vertical frame 11 and into the first mounting hole 33 to completely fix the connecting assembly 3 to the vertical frame 11;

[0033] After the vertical frame 11 is fixed to the first connecting block 31, take out the transverse frame 12, align the mounting cavity 15 on the transverse frame 12 with the bottom of the first connecting block 31 and insert it. At the same time, the sliding blocks 41 on the two limiting grooves 38 slide in the sliding grooves 16 on the transverse frame 12. When the two sliding blocks 41 slide to the ends of the sliding grooves 16, continue to push the first connecting block 31 into the transverse frame 12. Under the obstruction of the sliding grooves 16, the sliding blocks 41 move upward along the limiting grooves 38. When the sliding blocks 41 move upward, the squeeze The oblique side of the block 42 gradually pushes the second connecting block 36, causing the second connecting block 36 to extend outward from the first connecting block 31 and extend toward the transverse frame 12. When the first connecting block 31 is fully inserted into the transverse frame 12, the second mounting holes 37 on the second connecting block 36 are aligned with the screw holes on the transverse frame 12. The transverse frame 12 is fixed to the second connecting block 36 by the fixing bolts 13, thereby fixing the transverse frame 12 to the first connecting block 31. The vertical frame 11 is fixed to the transverse frame 12 through the first connecting block 31.

[0034] After fixing, take out the L-shaped reinforcing plate 18 and place it on the two fixing grooves 14 , screw it in, and further strengthen the connection between the vertical frame 11 and the horizontal frame 12 through the L-shaped reinforcing plate 18 .

[0035] When the first connecting block 31 is inserted, the top of the auxiliary reinforcing block 34 pushes the clamping block 23, so that the two clamping blocks 23 drive the connecting rod 22 to retract into the connecting groove 17. When the first connecting block 31 is continuously inserted, the auxiliary reinforcing block 34 moves upward. When the clamping groove 35 moves to the clamping block 23, the rebound force of the return spring 21 drives the connecting rod 22 and the clamping block 23 to pop out outward, so that the clamping block 23 is clamped on the clamping groove 35. The clamping groove 35 is fixed by the clamping block 23. After fixing, the fixing bolt 13 passes through the vertical frame 11 and is screwed into the first mounting hole 33, so that the connecting assembly 3 is completely fixed to the vertical frame 11.

[0036] After the vertical frame 11 is fixed to the first connecting block 31, the transverse frame 12 is taken out, and the mounting cavity 15 on the transverse frame 12 is aligned with the bottom of the first connecting block 31 and inserted. At the same time, the sliding blocks 41 on the two limiting grooves 38 slide in the sliding grooves 16 on the transverse frame 12. When the two sliding blocks 41 slide to the ends of the sliding grooves 16, the first connecting block 31 is continued to be pushed into the transverse frame 12. Under the obstruction of the sliding grooves 16, the sliding blocks 41 move upward along the limiting grooves 38. When the sliding blocks 41 move upward, the oblique edges of the extrusion blocks 42 push the second connecting blocks 36, causing the second connecting blocks 36 to extend from the first connecting blocks 31. When the first connecting block 31 is fully inserted into the transverse frame 12, the second mounting holes 37 on the second connecting blocks 36 are aligned with the screw holes on the transverse frame 12. The transverse frame 12 is fixed to the second connecting blocks 36 by the fixing bolts 13, thereby fixing the transverse frame 12 to the first connecting block 31, and the vertical frame 11 is fixed to the transverse frame 12 through the first connecting block 31.

[0037] After fixing, take out the L-shaped reinforcing plate 18 and place it on the two fixing grooves 14 , screw it in, and further strengthen the connection between the vertical frame 11 and the horizontal frame 12 through the L-shaped reinforcing plate 18 .
