Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-5The utility model provides a technical solution: a highly stable rotating shaft connector, comprising a first connecting block 1, the inner wall of the first connecting block 1 being rotatably connected to a rotating shaft body 2, the surface of the rotating shaft body 2 being sleeved with a second connecting block 4, the end of the rotating shaft body 2 close to the second connecting block 4 being fixedly connected to a limiting plate 3, the surface of the rotating shaft body 2 being sleeved with a third connecting block 5, the end of the third connecting block 5 close to the second connecting block 4 being fixedly connected to two limiting rods 6, the surface of the second connecting block 4 being fixedly connected to a first "U"-shaped plate 7, and the surface of the third connecting block 5 being fixedly connected to a second "U"-shaped plate 11. By providing the second connecting block 4, the third connecting block 5 and the limiting plate 3, the connection stability of the rotating shaft connector can be improved as much as possible, and by providing the limiting rod 6, the positional stability of the second connecting block 4 and the third connecting block 5 can be increased.

[0030] The following is a detailed description of its overall specific settings and functions.

[0031] like Figure 1-Figure 5 As shown, the first "U"-shaped plate 7 is fixedly connected to the first fixed plate 8 on the side close to the rotating shaft body 2, and the second "U"-shaped plate 11 is fixedly connected to the second fixed plate 12 on the side close to the rotating shaft body 2. By providing the first fixed plate 8 and the second fixed plate 12, the first "U"-shaped plate 7 and the second "U"-shaped plate 11 can be conveniently connected. The inner wall of the first fixed plate 8 is threadedly inserted with a screw rod 9, and the screw rod 9 is threadedly inserted into the inner wall of the second fixed plate 12. The screw rod 9 threadedly inserted into the inner wall of the first fixed plate 8 and the second fixed plate 12 can be rotated, and the first fixed plate 8 and the second fixed plate 12 can be connected through the screw rod 9. The end of the screw rod 9 close to the second fixed plate 12 is fixedly connected to a rectangular block 13, and the end of the screw rod 9 away from the rectangular block 13 is fixedly connected to a rotating plate 10. By providing the rotating plate 10, the screw rod 9 can be conveniently rotated, and by providing the rectangular block 13, the rotation of the screw rod 9 can be conveniently restricted.

[0032] The inner wall of the second fixed plate 12 is slidably connected to a slide bar 16, and the end of the slide bar 16 near the rectangular block 13 is fixedly connected to the connecting plate 15. The slide bar 16 slidably connected to the inner wall of the second fixed plate 12 can move. By moving the slide bar 16, the connecting plate 15 can be easily moved. By providing the slide bar 16, the connecting plate 15 can be connected to the second fixed plate 12. The side of the connecting plate 15 near the rectangular block 13 is fixedly connected to a limiting sleeve 14, which is sleeved on the surface of the rectangular block 13. By moving the connecting plate 15, the limiting sleeve 14 can be controlled to move closer to or away from the rectangular block 13, thereby conveniently restricting or releasing the restriction of the rectangular block 13. The end of the slide bar 16 away from the limiting sleeve 14 is fixedly connected to a baffle 18. The surface of the slide bar 16 is sleeved with a spring 17, and the two ends of the spring 17 are fixedly connected to the second fixed plate 12 and the connecting plate 15, respectively. By providing the baffle 18 and the spring 17 , a stable connection between the slide bar 16 and the second fixing plate 12 can be ensured. By providing the spring 17 , the position of the connecting plate 15 can be restricted.

[0033] Working principle: When assembling a highly stable rotating shaft connector, pull the limiting sleeve 14 to move the connecting plate 15 away from the second fixed plate 12, rotate the rotating plate 10 to drive the screw 9 to rotate on the inner wall of the first fixed plate 8, so that the screw 9 rotates close to the second fixed plate 12, thereby completing the connection between the first fixed plate 8 and the second fixed plate 12, and then loosen the limiting sleeve 14. Under the action of the elastic force of the spring 17, the sliding rod 16 slides on the inner wall of the second fixed plate 12, so that the limiting sleeve 14 moves close to the rectangular block 13, restricting the screw 9, and completing the assembly of the rotating shaft connector, so that the second connecting block 4 and the second U-shaped plate 7 and the second U-shaped plate 11 as well as the screw 9 can be raised. The stability of the connection between the third connecting blocks 5 can be improved by setting the baffle 18, which can ensure that the sliding rod 16 will not separate from the second fixed plate 12. By setting the limit plate 3 and the limit rod 6, the stability of the connection between the first connecting block 1, the second connecting block 4 and the third connecting block 5 and the rotating shaft body 2 can be improved. By setting the first "U"-shaped plate 7 and the second "U"-shaped plate 11, the relative fixation of the position between the second connecting block 4 and the third connecting block 5 can be improved. By setting the limit sleeve 14 and the rectangular block 13, the stability of the connection between the first fixed plate 8 and the second fixed plate 12 can be improved, thereby improving the stability of the rotating shaft connector during use and ensuring the service life of the rotating shaft connector as much as possible.
