DETAILED DESCRIPTION

[0020] The utility model is further described below in conjunction with the accompanying drawings:

[0021] Embodiment 1:

The inner wall of the outer shell 1 is slidably engaged with the outer wall of the vertical cylinder 4. The vertical cylinder 4 is subjected to force and slides up and down through the inner wall of the outer shell 1. The outer wall of the outer shell 1 is connected to a fixed structure 2. The front and rear sides of the top of the fixed structure 2 are respectively processed with round openings 6. A motor 7 is fixedly connected to the top of the inner wall of the outer shell 1. The motor 7 is a servo motor model selected according to usage requirements. A second screw 8 is fixedly connected to the output end of the motor 7. The outer wall of the second screw 8 is threadedly connected to the inner wall of the vertical cylinder 4. The second screw 8 rotates to drive the vertical cylinder 4 to slide up and down on the inner wall of the outer shell 1. A base frame 5 is fixedly connected to the bottom of the vertical cylinder 4. A clamping structure 9 is connected to the bottom notch of the vertical cylinder 4. The outer wall of the clamping structure 9 is slidably engaged with the inner wall of the base frame 5. The base frame 5 is located below the fixed structure 2.

[0023] The fixed structure 2 includes a square frame 201 and a vertical plate 202. The inner wall of the square frame 201 is slidably engaged with the lower outer wall of the shell 1. The shell 1 slides left and right through the inner wall of the square frame 201 under force. The left and right ends of the square frame 201 are respectively fixedly connected to the inner top of the vertical plate 202. The bottom of the vertical plate 202 is fixedly connected with a bracket 203. The bottom of the bracket 203 is threadedly connected with a first screw rod 204. The top of the outer wall of the first screw rod 204 is rotatably connected with a clamping plate 205. The top of the outer wall of the first screw rod 204 is rotated through the bearing at the bottom of the clamping plate 205 under force. The bottom of the first screw rod 204 is fixedly connected with a handle 206. The handle 206 is convenient for driving the first screw rod 204 to rotate. The outer side of the clamping plate 205 fits with the inner wall of the bracket 203. The front and rear sides of the top of the square frame 201 are respectively processed with a plurality of round openings 6.

Then the handle 206 rotates the first screw 204 upward, thereby moving the splint 205 upward, so that the top of the splint 205 cooperates with the bracket 203 to press the window frame tightly to complete the fixation. At the same time, the vertical plate 202 cooperates with the square frame 201 to prevent the device from shaking, reduce the operating difficulty of the auxiliary pulling device, and eliminate the safety hazards of the auxiliary pulling device.

[0025] The base frame 5 is located below the square frame 201, and the clamping structure 9 includes a cylinder 901 and a slot plate 902. The top of the cylinder 901 is fixedly connected to the bottom slot of the vertical tube 4. The model of the cylinder 901 is selected according to the use requirements. The output end of the cylinder 901 is fixedly connected to the top of the slot plate 902. The inner wall of the slot plate 902 is slidably clamped with a round block 903. The slot plate 902 moves up and down, which can make the round block 903 slide left and right.

[0026] Working principle:

[0027] Device fixing:

[0028] First, cooperate with the handle 206 to move the first screw 204 downward through the bracket 203, and then plug the space between the bracket 203 and the splint 205 into the side of the bed frame. Then, the handle 206 rotates the first screw 204 upward, thereby moving the splint 205 upward, so that the top of the splint 205 cooperates with the bracket 203 to press the window frame tightly to complete the fixation. At the same time, the vertical plate 202 cooperates with the square frame 201 to prevent the device from shaking.

[0029] Device operation:

[0030] The bone implant is located on the inner side of the second vertical plate 904, and then the cylinder 901 works to move the output end downward, thereby moving the slot plate 902 downward, and the moving slot plate 902 moves the round block 903 inward, thereby moving the second vertical plate 904 inward to press the bone implant tightly, and then the motor 7 is powered on, and the output end of the motor 7 rotates with the second screw 8, and the rotating second screw 8 causes the vertical tube 4 to move downward on the outer wall of the shell 1, thereby cooperating with the positioning structure 3 to move the bone implant downward, so that the bone implant is gradually driven into the specified position, and the above operation is reversed to pull out the bone implant.

[0031] Embodiment 2:

[0032] See also Figure 1-6: In this embodiment, an auxiliary pulling device also includes a positioning structure 3, the positioning structure 3 includes a horizontal plate 301 and a vertical rod 302, the inner sides of the two horizontal plates 301 are respectively fixedly connected to the front and rear sides of the outer shell 1, the inner wall of the horizontal plate 301 is slidably engaged with the outer wall of the vertical rod 302, the top of the vertical rod 302 is fixedly connected with a curved rod 303, and the bottom of the outer wall of the vertical tube 302 is plugged into the inner wall of the circular mouth 6.

[0033] Working principle:

[0034] When adjusting the position of the device, the curved rod 303 is pulled upward, so that the vertical rod 302 moves upward through the horizontal plate 301, and the bottom of the vertical rod 302 is separated from the inner wall of the circular opening 6. Then the outer shell 1 slides left and right on the inner wall of the square frame 201 to adjust the position. Then the curved rod 303 moves downward with the vertical rod 302, so that the bottom of the outer wall of the vertical rod 302 is plugged into the corresponding circular opening 6, thereby completing the fixation of the outer shell 1.
