Preferably, the damper 6 is a damper that limits the stretching of the piston rod, or other damping mechanism that limits the pulling out of its piston rod.

[0051] Preferably, the connecting shaft 44 or the connecting block can be arranged on the two side plates of the shell 4 or the top plate of the shell 4 or the middle plate added to the shell 4, such as fixing the connecting shaft on the middle plate installed on the shell, and the connecting shaft can be fixed on the shell by stamping, or screwing it on the shell or other known installation methods, which can achieve the expected technical effect and purpose.

[0052] As a preference, The transmission member includes a second linking member 3 located on one side of the damper bearing seat 1 corresponding to the side linking member 3. The moving part 13 is provided with a transmission tooth part 31. Preferably, the transmission tooth portion 31 of the second linking member 3 extends from one side of the second linking member 3 body toward the damper bearing seat 1. When the second linking member 3 rotates, the transmission tooth portion 31 transmits the damper The side linkage part of the support base 1 enables the damper support base 1 to move in the housing 4.

[0053] As a preference, The damper cavity 16 of the damper bearing seat 1 has an opening on one side opposite to the rear side plate 103. The damper 6 is arranged in the direction of the torsion spring and is installed in the damper bearing seat 1 .

[0054] Preferably, in a specific connection mode, the piston rod 61 of the damper 6 has a connecting ring 62 on one side of the connecting shaft 44 , and the connecting shaft 44 is passed through the connecting ring 62 .

[0055] Preferably, the connecting ring 62 on the piston rod 61 of the damper 6 is formed by bending the piston rod to form an annular hook for passing the connecting shaft. During processing, the piston rod is bent to reduce the number of intermediate connecting parts. When in use, the stability is further improved. The annular hook for passing the connecting shaft can be formed by bending the piston rod only by selecting a more appropriate length of the piston rod.

[0056] Preferably, the rear side plate 103 of the damper bearing seat 1 is provided with a through hole 17 for the connecting ring 62 to pass through so as to facilitate the connecting ring 62 to connect to the connecting shaft 44 and facilitate the overall process.

[0057] Preferably, the connecting shaft 44 is installed on the two side plates of the housing 4, and the connecting shaft 44 is fixed at the extended position of the piston rod 61 of the damper 6 to keep the damper bearing seat 1 in the expected sliding axial direction during movement.

[0060] In this embodiment, the limiting rod 43 can be used to limit the overall movement of the damper bearing seat 1 within the housing 4 when the hinge cup 2 rotates, thereby preventing the damper bearing seat 1 from being separated from the housing 4.

[0061] Preferably, a gap is left between the damper bearing seat 1 and the connecting shaft 44. Specifically, the gap is used to reserve a gap to prevent the damper bearing seat from colliding with the connecting shaft when pulling back.

[0062] When this embodiment is used, when the torsion spring is reset, the hinge cup rotates to drive the second link to rotate, and the transmission tooth portion of the second link drives the link of the damper support seat to move as a whole in the direction of the torsion spring. Since the piston rod of the damper is hung on the connecting shaft and the stretching effect of the limiting piston rod of the damper generates a reverse force that causes the damper support seat to move in the direction of the connecting shaft, thereby overcoming the resistance of the torsion spring to reset and achieving a buffering effect.

[0063] Of course, the above are only preferred embodiments of the present invention, and are not intended to limit the scope of use of the present invention. Therefore, any equivalent changes made to the principles of the present invention should be included in the protection scope of the present invention.
