In this embodiment, the connecting rods 707 are uniformly distributed along the circumferential direction on the circumference around the center of the shaft i 705a, so as to ensure the symmetry of the shaft i 705a, avoid uneven mass distribution, and improve the coaxiality of rotation. The right end face of the shaft I705 a extends outwards along the axial direction to form an extension rod 711, the left end face of the shaft II 705b is recessed inwards along the axial direction to form a supporting blind hole 712 for the extension rod 711 to coaxially extend into, and the rod diameter of the extension rod 711 is 1.0-3.0mm smaller than the aperture of the supporting blind hole 712. The extension rod 711 can be 1/8-1/5 of the length of the shaft I705 a, the diameter of the extension rod is 1/2 of the diameter of the shaft I705 a, and the depth of the supporting blind hole 712 is slightly larger than that of the extension rod 711; the extension rod 711 can be contacted with the inner wall of the supporting blind hole 712 under the action of gravity, but even if the extension rod 711 is contacted with the inner wall of the supporting blind hole 712, the transmission effect between the extension rod 711 and the supporting blind hole is extremely small, and the extension rod 711 is prevented from being driven when the shaft II 705b rotates independently; of course, the support ring is additionally arranged to support the connection part of the shaft I705 a and the shaft II 705b, so that the contact between the extension rod 711 and the inner wall of the support blind hole 712 can be avoided; through extension rod 711 and support blind hole 712, axle I705 a and axle II 705b can support each other, are favorable to simplifying pivot 705 structure, improve the axiality of axle I705 a and axle II 705 b. The length of the connecting rod 707 is greater than the length of the axial through hole 708 but less than the sum of the lengths of the axial through hole 708 and the axial blind hole 709, and the left end of the connecting rod 707 is connected with an operating handle 715. The connecting rod 707 is moved by screwing or pushing the operating handle 715, so that the connecting rod 707 is conveniently operated; the outer surface of the lever 715 may be provided with anti-slip threads.
In this embodiment, the portions of the shafts i 705a and ii 705b located in the inner cavity 702 are provided with (or may be provided only on the shafts i 705a and ii 705b) a spiral bar 713 for spirally pushing the silicone oil 706. The spiral strip is beneficial to increasing the contact surface of the rotating shaft 705 and the silicone oil 706, and the shearing action on the silicone oil 706 is improved, so that the damping force is increased; meanwhile, the spiral strips 713 push the silicone oil 706 to flow, so that the silicone oil 706 can be prevented from going bad, and the silicone oil 706 is prevented from settling due to long-time standing; the flowing silicone oil 706 has the effect of mutual exchange, and is beneficial to the transfer and the emission of heat of the silicone oil 706; an annular sleeve 714 which is coaxial with the rotating shaft 705 is arranged in the inner cavity 702, the left end face of the annular sleeve 714 is fixedly connected to a left end cover 701b of the cylinder body 701, gaps are respectively arranged between the right end face of the annular sleeve 714 and the right end face of the cylinder body 701 and between the outer wall of the annular sleeve 714 and the inner wall of the cylinder body 701, the shaft I705 a and the shaft II 705b are partially arranged in an inner flow passage of the annular sleeve 714, a flow hole 714a for communicating the gaps and the inner flow passage is formed in the annular sleeve 714, and the silicone oil 706 circularly flows in the flow passage formed by the gaps, the inner flow passage and the flow hole 714a under the pushing of the spiral strip. The annular sleeve 714 is also of a metal structure and can be fixed by fastening bolts; this structure allows the silicone oil 706 to have a specific flow path, further preventing deterioration of the silicone oil 706. Preferably, the flow holes 714a are provided near the left end surface of the annular sleeve 714 so that the flow path of the silicone oil 706 can be extended.
The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent. The scope of the claims of the present application shall be determined by the contents of the claims, and the description of the embodiments and the like in the specification shall be used to explain the contents of the claims.
