[0024] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0025] Figure 1-7 A sofa iron frame that can be quickly assembled is shown, comprising two sofa iron frame parts 1, which are arranged symmetrically on the left and right. A sofa sponge layer 2 is installed on the upper ends of the two sofa iron frame parts 1, and a plurality of stud hollow sleeves 4 are arranged between the sofa sponge layer 2 and the sofa iron frame parts 1. The inner ends of the stud hollow sleeves 4 are threadedly connected with fastening screws 3, and the upper ends of the stud hollow sleeves 4 are in contact with two magnetic surface connection blocks 7, and the upper ends of the magnetic surface connection blocks 7 are fixedly connected with vertical spring connectors 8, and the upper ends of the two vertical spring connectors 8 are fixedly connected with clamp discs 9, and the inner ends of the clamp discs 9 are provided with hollow openings 12, and the inner ends of the hollow openings 12 are provided with adaptive bearing inner parts 10, and the inner ends of the adaptive bearing inner parts 10 are provided with L-shaped screw turning tools 11, and the upper ends of the fastening screws 3 are fixedly connected with upper protruding transverse pieces 5, and the upper ends of the upper protruding transverse pieces 5 are provided with docking grooves 6.

[0026] Figure 1-7 It shows that the L-shaped screw turning tool 11 and the docking groove 6 are docked with each other, the outer wall of the stud hollow sleeve 4 is fixedly connected with a barbed friction enhancement layer 15, and the barbed friction enhancement layer 15 is in contact with the inner wall of the sofa sponge layer 2. The upper outer wall of the L-shaped screw turning tool 11 is provided with an anti-slip convex pattern 14, and the anti-slip convex pattern 14 is located above the smooth outer layer 13. The magnetic surface connecting block 7 and the upper wall of the stud hollow sleeve 4 are magnetically detachably connected. The sofa iron frame 1 and the sofa sponge layer 2 are connected to each other by fastening screws 3, and the upper protruding horizontal piece 5 is located between the two vertical spring connectors 8.

[0027] Figure 1-7The present invention shows that during the assembly process, the sofa sponge layer 2 is placed on the two sofa iron frame parts 1 for preliminary engagement, and the two are further tightly locked together by using the fastening screws 3. When the sofa iron frame part 1 and the sofa sponge layer 2 are locked and assembled, the sofa iron frame part 1 and the sofa sponge layer 2 are reversed as a whole so that the installation path of the fastening screws 3 is level with the ground. After the fastening screws 3 are inserted into the stud hollow sleeve 4, the L-shaped screw turning tool 11 inserted into the fixture disc 9 is aligned with the docking notch 6 above the fastening screws 3. At this time, the two magnetic surface connecting blocks 7 placed on the fixture disc 9 use their magnetism to contact the upper wall surface of the stud hollow sleeve 4 and magnetize the L-shaped screw turning tool 11 to have a support frame during the rotation and advancement process. The vertical spring connector 8 can be compressed during the screwing process of the L-shaped screw turning tool 11. This method can ensure that the L-shaped screw After the screw-in path is paused, the screw-twisting tool 11 is still tightly docked with the docking groove 6 on the fastening screw 3. In this way, the assembler does not need to spend time to realign the L-shaped screw-twisting tool 11 with the docking groove 6 on the fastening screw 3, making the installation process smoother. The assembler can perform the bolt tightening operation more consistently, saving time, labor and efficiency. At the same time, anti-slip convex grooves 14 are provided at the connection between the L-shaped screw-twisting tool 11 and the assembler. The anti-slip convex grooves 14 can increase the contact surface between the assembler's hand and the L-shaped screw-twisting tool 11, making it have an anti-slip function, making the screw-in process smoother, and a barbed friction enhancement layer 15 is provided on the outside of the stud hollow sleeve 4. The stud hollow sleeve 4 is mainly used to provide additional support and guidance. The barbed friction enhancement layer 15 can increase the friction between the contact surface and prevent the risk of relative sliding and loosening.
