Through the setting of the adjustment component 10 and the swing component 8, it is beneficial to realize the multi-directional adjustment of the screw 1111, which is beneficial to improving the convenience of using the device.

[0028] See also Figure 2In order to improve the flexibility of the device, the swing assembly 8 in this embodiment includes a fixed base 801 fixed to the right side of the connecting plate 1, and a sliding plate 802 is slidably connected to the inner side of the fixed base 801. Connecting openings are provided on the upper and lower sides of the fixed base 801, and a sliding opening connected to the connecting opening is provided on the right side of the fixed base 801.

[0029] It can be understood that the setting of the connecting port and the sliding port is conducive to the sliding of the sliding plate 802, thereby facilitating the left and right swing adjustment with the connecting block 807, facilitating the stable use of the device, and thus facilitating the improvement of the use effect of the device.

[0030] The sliding plate 802 is slidably connected to the sliding plate 802 through the sliding port. A driving assembly 9 is provided on the sliding plate 802. A disc 803 is fixed on the driving assembly 9. The left side of the top of the disc 803 is movably connected to a movable ring 804 extending to its bottom.

[0031] In this embodiment, by setting the movable ring 804 and rotating the disc 803, the fixed column 805 is driven to swing back and forth, which is beneficial to realize the front and rear displacement adjustment of the screw 1111 through the hinge setting of the box body 7 and the connecting plate 1, and is beneficial to improving the overall flexibility of use.

[0032] See also Figure 3 In order to improve the accuracy of use, the driving assembly 9 in this embodiment includes a rotating shaft 901 fixed to the top of the disc 803, and the outer side of the rotating shaft 901 is rotatably connected to a fixed sleeve 902 fixed to the inner side of the sliding plate 802.

[0033] In this embodiment, the provision of the semicircular gear block facilitates differential setting of the meshing transmission between the annular gear plate 906 and the rotating gear 903, thereby improving the accuracy of the overall device. Meanwhile, the provision of the rotating disk 905 facilitates adjustment of the overall drive assembly 9, thereby improving the overall convenience of use.

[0034] See also Figure 4In order to further improve the flexibility of the device, the adjustment component 10 in this embodiment includes a rotating shaft 1002 rotatably connected to the front and rear inner walls of the box body 7, the front of the rotating shaft 1002 extends to the outside of the box body 7, a turntable 1001 is fixed to the front of the rotating shaft 1002, a worm 1003 is fixed to the outside of the rotating shaft 1002, a worm gear 1004 is engaged with the right side of the worm 1003, and rotating rods 1005 are fixed to the upper and lower sides of the worm gear 1004. The top rotating rod 1005 is rotatably connected to the inner wall of the top of the box body 7, and a rotating gear 1006 is fixed to the bottom of the bottom rotating rod 1005.

[0035] It can also be understood that by rotating the turntable 1001, the worm gear 1004 is rotated through the meshing action, thereby driving the rotating rod 1005 to rotate, and the tooth plate 1008 is driven to move through the meshing action, which is conducive to the realization of the forward and backward adjustment function of the screw 1111.

[0036] It should be noted that a connecting seat 1007 is fixed on the inner cavity wall on the left side of the box body 7, and the front of the connecting seat 1007 is slidingly connected to a tooth plate 1008 that engages with the back of the rotating gear 1006. A sliding channel is opened on the front of the connecting seat 1007, and the tooth plate 1008 is slidingly connected to the connecting seat 1007 through the sliding channel. A receiving plate 1009 is fixed to the right side of the tooth plate 1008, and two front and rear springs 1010 are fixed on the inner cavity wall on the left side of the box body 7, and a stabilizing plate 1011 is fixed to the right side of the spring 1010.

[0037] In this embodiment, the setting of the sliding channel is conducive to the left and right sliding of the tooth plate 1008, thereby helping to improve the stability of the supporting plate 1009 on the outer cylinder 1106, thereby helping to achieve stable adjustment of the screw 1111, and the setting of the spring 1010 is conducive to tightening the outer cylinder 1106, which is conducive to further improving the stability of use.

[0038] See also Figure 5 In order to improve the use effect, the working component 11 in this embodiment includes a rotating rod 1101 rotatably connected to the inner wall of the left side of the box body 7, the right side of the rotating rod 1101 extends to the outside of the box body 7, and a driving gear 1102 located in the inner cavity of the box body 7 is fixed to the outside of the rotating rod 1101. The bottom of the driving gear 1102 is engaged with a driven gear 1103, and a threaded rod 1104 is fixed at the axis of the bottom of the driven gear 1103. The bottom of the connecting block 807 is fixed with two front and rear connecting plates 1105, and an outer cylinder 1106 is fixed between the front and rear connecting plates 1105. The inner side of the outer cylinder 1106 is slidably connected to an inner cylinder 1107 threadedly connected to the outer side of the threaded rod 1104.

[0039] It can be found that through the sliding connection setting of the inner cylinder 1107 and the outer cylinder 1106, and the threaded connection between the inner cylinder 1107 and the threaded rod 1104, the displacement sliding of the inner cylinder 1107 is realized, thereby supporting the supporting column 1110, which is beneficial to supporting the connecting plate 11092, and is beneficial to achieving the downward pressure of the screw 1111, which is beneficial to improving the tightening effect.

[0040] A sleeve 1108 is fixed to the bottom of the threaded rod 1104, and a connecting component 1109 is provided on the inner side of the sleeve 1108. A top support column 1110 that is rotatably connected to the bottom of the inner cylinder 1107 is fixed on the connecting component 1109. A rotating opening is provided at the bottom of the inner cylinder 1107, and the top of the top support column 1110 is rotatably connected to a rotating wheel located in the rotating opening. A screw 1111 is clamped on the connecting component 1109.

[0041] In this embodiment, the provision of the rotating wheel helps to reduce the friction between the top support column 1110 and the inner cylinder 1107 during rotation, thereby helping to improve the stability of the overall assembly. The provision of the rotating mouth helps to limit the top support column 1110, thereby helping to improve the overall stability of use.

[0042] See also Figure 6 In order to ensure the stability of the screw 1111, the connecting component 1109 in this embodiment includes a column 11091 that is plugged into the inner side of the sleeve 1108. The bottom of the sleeve 1108 is provided with an insertion interface. The column 11091 is plugged into the sleeve 1108 through the insertion interface. A connecting plate 11092 is fixed to the bottom of the column 11091. The top of the connecting plate 11092 is fixed to the top support column 1110. A cross block 11093 is fixed to the inner bottom wall of the connecting plate 11092.

[0043] It can also be found that by plugging the cross block 11093 into the screw 1111, the screw 1111 is initially limited, which is beneficial to improving the stability of the device. The setting of the plug interface is beneficial to the plugging of the column 11091, which is beneficial to the displacement and sliding of the column 11091, which is beneficial to improving the stability of the overall device.

[0044] A locking hole is provided at the top of the screw 1111, and the cross block 11093 is locked with the top of the screw 1111 through the locking hole. Magnetic sheets 11094 are fixed on the inner cavity walls on the left and right sides of the connecting plate 11092. The screw 1111 is slidably connected to the outer side of the cross block 11093, and the outer side of the screw 1111 is in contact with the magnetic sheet 11094.

[0045] In this embodiment, the provision of the magnetic sheet 11094 facilitates the adsorption of the screw 1111, thereby facilitating the improvement of the stability of the use of the screw 1111. At the same time, the cross block 11093 limits the screw 1111, ensuring the stable rotation of the screw 1111, thereby achieving stable rotation and tightening of the screw 1111, which is beneficial to improving the overall stability of use.

[0046] The electrical components mentioned herein are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by a person skilled in the art. The provision of power is also common knowledge in the art. The present invention is mainly used to protect mechanical devices, so the control method and circuit connection are not explained in detail in the present invention.

[0047] The working principle of the above embodiment is:

[0048] (1) After determining the position of the patient's mouth, place the edge of the recliner between the pressure plate 6 and the bottom plate 4. The pressure plate 6 is pressed down by rotating the bolt 5 to stabilize the entire device. The screw 1111 is inserted into the connecting plate 11092. Then, the height of the electric push rod 3 is adjusted by the button on the handle 2 to move the screw 1111 closer to the buried point. By rotating the rotating disk 905, the annular gear disk 906 is driven to rotate. The structural setting of the annular gear disk 906 reduces the rotation transmission ratio, thereby improving the rotation accuracy of the rotating shaft 901. By rotating the rotating shaft 901, the disc 803 is driven to rotate, thereby realizing the front and rear displacement of the movable ring 804, thereby driving the fixed column 805 to move forward and backward. The front and rear position of the screw 1111 is adjusted by the rotation connection effect of the box body 7 and the connecting plate 1.

[0049] (2) Rotating the turntable 1001 drives the worm 1003 to rotate, and the worm wheel 1004 is driven to rotate through the meshing action, thereby driving the rotating gear 1006 to rotate through the rotating rod 1005, and the tooth plate 1008 is displaced through the meshing action, thereby lifting the outer cylinder 1106 through the receiving plate 1009, and at the same time, the outer cylinder 1106 is tightened by the spring 1010, and the connecting plate 1105 is rotated through the connecting block 807 and the box body 7 through the rotation connection action of the connecting block 807 and the box body 7, thereby driving the screw 1111 to swing left and right for displacement adjustment, thereby realizing multi-directional micro-adjustment of the screw 1111.

[0050] (3) After the drilling point is determined, the rotating rod 1101 is rotated to drive the driven gear 1103 to rotate through the meshing action, and the sleeve 1108 is driven to rotate through the fixing action, thereby driving the screw 1111 to rotate. At the same time, through the threaded connection setting of the inner cylinder 1107 and the sliding connection with the outer cylinder 1106, the inner cylinder 1107 is moved downward, thereby pressing the supporting column 1110 downward, so that the insertion column 11091 slides downward in the sleeve 1108, thereby realizing the rotation of the screw 1111 while pressing downward, which is conducive to the stable tightening of the bone screw. The overall device has a simple structure, convenient operation, good adjustment effect and high tightening efficiency.
