And the magnetic pole of the magnet at the bottom end of the bolt 52 is different from the magnetic pole of the magnet at the top end of the third jack 515, and the magnetic force of the magnet is greater than the elastic force of the second spring 510.

[0052] Refer to Figure 8 and Figure 9, a sleeve 517 is fixedly connected to the bottom end of the skateboard 45. The outer wall shape of the sleeve 517 fits the inner wall shape of the arc-shaped chute opened at the top of the fixed ring 3. A positioning ball 518 is slidably connected to the inner wall of the sleeve 517. The shape of the positioning ball 518 is formed by connecting a hemispherical shape at the bottom and a cuboid shape above. The distance between the projection of the positioning ball 518 and the second jack 514 is an integer multiple of the distance between the two positioning grooves 516.

One end of the third spring 519 is fixedly connected to the top end of the positioning ball 518, and the other end of the third spring 519 is fixedly connected to the inner wall of the sleeve 517.

[0053] Referring to Figures 1 - 3 , a clamp 6 is arranged outside the bracket 1. The clamp 6 can fix the bracket 1 to the operating bed and can adjust the height of the bracket 1. And this technology is the prior art and can be realized by those skilled in the art, so it will not be described in detail in this case. A screw rod 7 is penetrated and threadedly connected to the inner wall of the mounting sleeve 2. The bottom end of the screw rod 7 is fixedly connected to a pressing plate 8. The outer wall of the pressing plate 8 is slidably connected to the inner wall of the mounting sleeve 2.

[0054] Working principle: During use, the staff first fixes the bracket 1 to the operating bed through the clamp 6, and adjusts the horizontal position of the fixed ring 3 by moving the horizontal position of the mounting sleeve 2. After the adjustment is completed, the staff rotates the screw rod 7 to make the pressing plate 8 closely adhere to the outer wall of the bracket 1, so that the positions of the bracket 1 and the mounting sleeve 2 are fixed.

[0055] After the fixation is completed, the staff rotates the slider 42 to a suitable position, and then pushes the mounting frame 43, so that the mounting frame 43 drives the pulling hook one 44 and the pulling hook two 47 to move. After the position of the pulling hook one 44 is adjusted, the staff rotates the first threaded rod 411, so that the first threaded rod 411 drives the pushing block 48 to move, so that the pushing block 48 drives the skateboard 45, the control bar 46 and the pulling hook two 47 to move, so as to adjust the relative distance between the pulling hook two 47 and the pulling hook one 44. Subsequently, the staff rotates the second threaded rod 412, so that the second threaded rod 412 drives the sliding block 49 and the triangular block 410 to move, so as to drive the control bar 46 to rotate through the cut angle of the control bar 46, so as to adjust the distance between the pulling hook two 47 and the pulling hook one 44.

[0056] After the adjustment is completed, the staff moves the pin 52 downward so that the pin 52 simultaneously enters the first jack 513, the second jack 514 and the third jack 515, so that the slider 42 is fixed relative to the fixed ring 3, and at the same time the position of the mounting frame 43 relative to the slider 42 is fixed.

[0057] Meanwhile, during the process of moving the bolt 52 downward, the bolt 52 drives the driving plate 53 to move downward, thereby driving the telescopic rod 54 to move downward through the driving plate 53, so that the telescopic rod 54 drives the pressing block 512 to move downward, so that the pressing block 512 pushes the starting block 59 through the inclined surface of the starting block 59, so that the area where the starting block 59 enters the air pressure block 58 increases, so that the gas inside the air pressure block 58 enters the airbag 511, so that the airbag 511 expands and fits with the first threaded rod 411 and the second threaded rod 412, so as to ensure that the first threaded rod 411 contacts the second threaded rod 412, and ensure that the positions of the first retractor 44 and the second retractor 47 will not change due to accidental contact with the first threaded rod 411 or the second threaded rod 412 during the operation, and ensure that the probability of accidents occurring during the operation is relatively small.

[0058] Meanwhile, during the process of moving the slider 42, since the positioning ball 518 is subjected to the elastic force of the third spring 519, the slider 42 can be controlled by the positioning ball 518 to keep the area where the positioning ball 518 is inside the positioning groove 516 during the moving process, so that it can be ensured that the second jack 514 and the third jack 515 are always coaxially arranged.

[0059] After the position adjustment is completed, the staff then cuts the position of the patient that needs surgery, and uses the first retractor 44 and the second retractor 47 with the adjusted positions to pull it to ensure the subsequent surgical effect.

[0060] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
