A connecting top seat 744 is fixedly connected to the top of the movable connecting rod 741. A movable connecting shaft 745 is movably connected inside the connecting top seat 744. A movable connecting arm 746 is fixedly sleeved on the outer side of the surface of the movable connecting shaft 745. The movable connecting arm 746 is connected and fixed to the inner side of the handrail body 1 and the inner side of the fixed inner groove 10 by bolts.

[0054] It facilitates the rotation of the movable connecting arm 746, movable connecting shaft 745, connecting top seat 744 and movable connecting rod 741, driving the connecting bottom block 742 and the first locking tooth 743 to rotate, thereby stably driving the limiting component 75 and making operation convenient.

[0055] In another embodiment, such as Figure 8 As shown, the limiting component 75 includes a movable limiting plug 751. A second locking tooth 752 is provided at equal intervals on one side of the movable limiting plug 751. The second locking tooth 752 and the first locking tooth 743 are engaged with each other. The outer side of the movable limiting plug 751 slides against the inner side of the second through groove 732 and the first through groove 723.

[0056] The first locking tooth 743 can rotate, allowing the second locking tooth 752 to move, which in turn moves the movable limiting block 751, allowing the end of the movable limiting block 751 to engage with the inside of the sofa base for connection and positioning, making operation convenient.

[0057] In another embodiment, such as Figure 9 As shown, the connecting positioning mechanism 14 includes a fourth leg 141.

A movable connecting block 144 is movably connected between the inner side of the connecting mounting frame 142 and the outer side of the fixed guide block 143. A rectangular groove 145 is opened at one end of the movable connecting block 144. A force-bearing spring 147 is fixedly connected between one side of the movable connecting block 144 and one inner end of the connecting mounting frame 142. A connecting rod 146 is fixedly connected to the side of the movable connecting block 144 away from the force-bearing spring 147. The outer side of the end surface of the connecting rod 146 slides and fits against the inner side of the third through hole 13.

[0058] The rectangular groove 145 facilitates the movement of the movable connecting block 144, allowing the movable connecting block 144 to move inside the connecting mounting frame 142 and outside the surface of the fixed guide block 143, thereby driving the connecting rod 146 to move and compressing the force spring 147, thus achieving a stable connection and making operation convenient.

[0059] In another embodiment, such as Figure 10 and Figure 11As shown, the movable storage mechanism 15 includes a movable mounting plate 151. A connecting top block 152 is fixedly connected to the top center of the movable mounting plate 151. The outer surface of the connecting top block 152 slides against the inner surface of the fixed slot 11. The interior of the connecting top block 152 is against the outer end of the connecting rod 146. A fixed bookshelf 153 is provided on the side of the movable mounting plate 151 near the armrest body 1. A fixed mounting inner groove 154 is symmetrically opened on the bottom surface of the movable mounting plate 151. Threaded holes 1510 are symmetrically opened on the lower part of the surface of the movable mounting plate 151. A fourth through hole 155 is opened on the lower part of both sides of the movable mounting plate 151. A first movable mounting block 156 is movably connected to the inner side of the fixed mounting inner groove 154. A connecting shaft 157 is fixedly connected to one side of the first movable mounting block 156. A rectangular slot 158 ​​is opened at one end of the first movable mounting block 156. An adjustment and reset assembly 159 is symmetrically provided on the lower part of one side of the movable mounting plate 151 by bolts.

[0060] This facilitates the movement of the first movable mounting block 156, which in turn moves the connecting shaft 157 to the inside of the fixed mounting groove 154, and drives the adjustment and reset assembly 159. At this time, the connecting shaft 157 can be pulled out from the inside of the limiting hole 9, thereby enabling the entire movable storage mechanism 15 to be quickly disassembled. Conversely, it can be quickly installed and used, making the operation convenient and quick.

[0061] In another embodiment, such as Figure 12 As shown, the adjustment and reset assembly 159 includes a fifth leg 1591. One end of the fifth leg 1591 is fixedly connected to a connecting mounting block 1592. One end of the connecting mounting block 1592 is fixedly connected to a reset spring 1593. The other end of the reset spring 1593 is fixedly connected to a second movable mounting block 1594. The outer side of the second movable mounting block 1594 and the inner side of the connecting mounting block 1592 slide against each other. One side of the second movable mounting block 1594 is fixedly connected to a rectangular insert 1595 that matches the rectangular slot 158.

[0062] When the first movable mounting block 156 moves, it can drive the rectangular insert block 1595 and the second movable mounting block 1594 to move, compressing the return spring 1593. Conversely, when the first movable mounting block 156 is released, the return spring 1593 can push the second movable mounting block 1594 and the rectangular insert block 1595 to reset on its own. The structure is simple and the operation is convenient and quick.

[0063] The working principle of this utility model is as follows: During use, a groove is first made on the sofa base to match the first connecting plug 4, the top cover body 721, the bottom frame body 731, and the movable limiting plug 751. Then, the connecting limiting mechanism 7 is moved as a whole, causing the movable connecting arm 746, the connecting top seat 744, the movable connecting shaft 745, and the movable connecting rod 741 to be inserted into the inner side of the fixed inner groove 10. The second support leg 71 is then connected and fixed to the armrest body 1 with bolts. Next, the first support leg 3 is fixed to the armrest body 1 with bolts, thus completing the connection and installation. Then, the first connecting plug 4 and the connecting limiting mechanism 7 are inserted into the inner side of the sofa base, and the movable connecting arm 746 is then moved to move the connecting rod 751. The connecting shaft 745 deflects inside the connecting top seat 744, making the movable connecting arm 746 parallel to the inner side of the armrest body 1. Then, the movable connecting arm 746 deflects, causing the movable connecting shaft 745, connecting top seat 744, movable connecting rod 741, connecting base block 742, and first locking tooth 743 to rotate. This causes the first locking tooth 743 to move the second locking tooth 752, thereby moving the movable limiting insert 751 so that its end can engage in the groove inside the sofa base. Finally, the movable connecting arm 746 and the armrest body 1 are connected and fixed with bolts, locking the internal components of the connecting limiting mechanism 7, thus completing the connection and installation. Then, when it is necessary to retrieve the books stored inside the movable storage mechanism 15, the movable connecting block 144 can be moved through the rectangular groove 145, allowing the movable connecting block 144 to move inside the connecting mounting frame 142 and outside the surface of the fixed guide block 143. This causes the connecting rod 146 to move, compressing the force spring 147, so that the end of the connecting rod 146 is pulled out from inside the connecting top block 152 and is no longer in a limiting position. Then, the second handle 21 is deflected, which causes the movable mounting plate 151 to deflect, allowing the end of the connecting shaft 157 to deflect inside the limiting insertion hole 9, thus unfolding and allowing the stored books to be retrieved. When the movable storage mechanism 15 needs to be disassembled as a whole, the first movable mounting block 156 can be moved, which drives the connecting shaft 157 to move, and drives the rectangular block 1595 and the second movable mounting block 1594 to move, compressing the return spring 1593, so that the end of the connecting shaft 157 can be pulled out from the inside of the limiting hole 9 for disassembly. Then, by moving the inner groove 19, the movable cover plate 18 can be moved, so that the movable cover plate 18 can move inside the fixed guide inner groove 16, exposing the cup placement groove 17, so that the cup can be placed inside the cup placement groove 17 for storage. The overall structure is simple and the operation is convenient and quick.

[0064] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
