An inner cavity 4 is opened at the end face of the first armrest frame. A guide rod 8, a spring 16 and a ring 17 are arranged in the inner cavity 4. A contact groove 9 is opened inside the inner cavity 4. A first through hole 11 is opened at the inner cavity 4. The first through hole 11 penetrates through the first armrest frame body 1. A first inner groove 10 is opened at one end of the first through hole 11. A second inner groove 18 is opened at the other end of the first through hole 11;

[0027] An insert block 5 is fixed to the end face of the second armrest frame body 3. A contact block 6 is arranged on the outer wall of the insert block 5. A second through hole 7 is opened on the surface of the insert block 5. The second through hole 7 penetrates through the insert block 5. A guide hole 14 is opened at the end face of the insert block 5;

[0028] A screw body 12, a screw buckle 2 is arranged at one end of the screw body 12, and a five-point nut 13 is arranged at the other end of the screw body 12;

[0029] During use, by removing the five-point nut 13 and pulling out the screw body 12 from the first through hole 11 and the second through hole 7, the limit can be released, and it is convenient to separate the first armrest frame body 1 and the second armrest frame body 3. When splicing is required, first insert the corresponding guide hole 14 into the guide rod 8. As the guide rod 8 continues to be inserted into the guide hole 14, the set insert block 5 will be correspondingly inserted into the inner cavity 4, and at the same time, the contact block 6 will be correspondingly inserted into the contact groove 9. Subsequently, when the first through hole 11 and the second through hole 7 correspond, insert the screw body 12 into the first through hole 11 and the second through hole 7, and then install the five-point nut 13, thereby realizing the splicing of the first armrest frame body 1 and the second armrest frame body 3.

[0030] Embodiment 2: On the basis of Embodiment 1, four groups of abutting grooves 9 are provided, and the four groups of abutting grooves 9 are evenly distributed inside the inner cavity 4. Four groups of abutting blocks 6 are provided, and the four groups of abutting blocks 6 are evenly distributed on the outer wall of the insertion block 5. The outer wall of the insertion block 5 is slidably connected to the inner wall of the inner cavity 4;

[0031] The cross-sections of the abutting block 6 and the abutting groove 9 are semi-circular, and the outer wall of the abutting block 6 is slidably connected to the inner wall of the abutting groove 9;

[0032] During use, four groups of abutting blocks 6 and abutting grooves 9 are provided, and the two are closely attached to each other to prevent the first armrest skeleton body 1 and the second armrest skeleton body 3 from rotating and shifting.

[0033] Embodiment 3: On the basis of Embodiment 2, two groups of guide rods 8 are provided, and the two groups of guide rods 8 are symmetrically distributed about the central axis of the inner cavity 4. The guide rods 8 are fixed to the bottom wall of the inner cavity 4. A spring 16 is sleeved on the surface of the guide rods 8. A ring 17 is slidably connected to the guide rods 8. One end of the spring 16 is fixedly connected to the ring 17, and the other end of the spring 16 is fixedly connected to the bottom wall of the inner cavity 4;

[0034] During use, the guide rods 8 extend out of the inner cavity 4. First, the corresponding guide rods 8 are inserted into the guide holes 14, which can provide guidance and support for the connection between the first armrest skeleton body 1 and the second armrest skeleton body 3. At the same time, the end faces of the guide rods 8 are chamfered to improve the smoothness of the connection;

[0035] At the same time, after the insertion block 5 is inserted into the inner cavity 4, the insertion block 5 will contact and squeeze the ring 17. At this time, the spring 16 will be compressed under force, and the spring 16 stores elastic potential energy. The spring 16 will give a pushing force to the second armrest skeleton body 3. Combined with the limiting effect of the subsequent screw body 12, the connection stability between the first armrest skeleton body 1 and the second armrest skeleton body 3 is further improved.

[0036] Embodiment 4: On the basis of Embodiment 3, the screw buckle 2 is fixedly welded to the end face of the screw body 12. The screw buckle 2 is embedded in the first inner groove 10. A pentagonal nut 13 is screwed onto the screw body 12, and the pentagonal nut 13 is located in the second inner groove 18;

[0037] During use, when the installation of the screw body 12 is completed, the provided screw buckle 2 will be embedded in the first inner groove 10, and at the same time, the pentagonal nut 13 will be embedded in the second inner groove 18 to prevent the screw buckle 2 and the pentagonal nut 13 from leaking out and ensure the flatness of the surface of the main skeleton.

[0038] In actual use, by removing the pentagonal nut 13 and pulling out the screw body 12 from the first through hole 11 and the second through hole 7, the limit can be released, facilitating the separation of the first armrest skeleton body 1 and the second armrest skeleton body 3. When splicing is required, first insert the guide hole 14 corresponding into the guide rod 8. As the guide rod 8 continues to be inserted into the guide hole 14, the provided insertion block 5 will be correspondingly inserted into the inner cavity 4, and at the same time, the abutting block 6 will be correspondingly inserted into the abutting groove 9. Subsequently, when the first through hole 11 and the second through hole 7 are aligned, insert the screw body 12 into the first through hole 11 and the second through hole 7, and then install the pentagonal nut 13, thereby realizing the splicing of the first armrest skeleton body 1 and the second armrest skeleton body 3. This avoids the problem that most traditional main skeletons are of an integrally formed structure, and the integrally formed main skeleton will face great difficulties during transportation.

[0039] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
