Example three:

The working principle is as follows: in the using process, an operator pulls the inserting rod 222 upwards, the inserting rod 222 can withdraw from the inside of the inserting groove 223 in the moving process, so that the mutual movement between the sliding seat 21 and the bed body 1 is not limited any more, at the moment, the operator pushes the support 24 according to the surgical position of a patient, the front position and the rear position of the draw hook 29 can be adjusted, the first spring 224 can be compressed in the moving process of the inserting rod 222, after the adjustment of the front position and the rear position is finished, the operator releases the inserting rod 222, at the moment, under the action of the resilience force of the first spring 224, the inserting rod 222 moves to reset and continues to be inserted into the inserting groove 223, and the stability of the whole device in the working process cannot be influenced;

then an operator energizes the electromagnet first 261, magnetism generated after the electromagnet first 261 is energized attracts the positioning rod 263 to move and drives the positioning rod 263 to withdraw from the positioning hole 264, the spring second 262 can be compressed in the moving process of the positioning rod 263, the moving of the movable block 25 is not limited at the moment, the operator can push the movable block 25 left and right according to actual needs at the moment, the position of the drag hook 29 can be adjusted to be right above the position to be operated, then the operator stops energizing the electromagnet first 261, at the moment, under the action of the resilience force of the spring second 262, the positioning rod 263 moves to reset and is continuously inserted into the positioning hole 264, and therefore the stability difference of the device during integral working cannot be affected;

then, an operator corresponds to the movable rod 282 on the external mounting block 27 of the drag hook 29 according to actual operation requirements, the movable rod 282 drives the connecting rod 283 to move when being pulled, the connecting rod 283 is driven to move to withdraw from the inside of the fixing hole 285 when the connecting rod 283 moves under the limiting action of the fixing rod 284, so that the movement of the mounting block 27 is not limited, at the moment, the operator can push the mounting block 27 to adjust the hooking angle of the drag hook 29, the movable rod 282 is released after the adjustment is completed, the movable rod 282 moves in the reverse direction and drives the fixing rod 284 to move and reset under the action of resilience of the spring 281, so that the fixed hole 285 is continuously spliced, the stability of the device in the working process is ensured, then the operator starts the air cylinder 23, the air cylinder 23 starts to drive the support 24 to move downwards, so that the drag hook 29 is subjected to three-dimensional position adjustment according to actual requirements, and the flexibility of the drag hook 29 in the using process is better, the stability is better in the using process;

when pulling, the operator hangs drag hook 29 on the incision, then rotate through pivot 31 and drive line wheel 32 and rotate, line wheel 32 rotates the in-process and can carry out the rolling to stay cord 33, under the guide effect of guide bar 34, stay cord 33 can drive drag hook 29 by the in-process of rolling and remove and carry out steady flaring to patient's incision, avoided the manual relatively poor condition that leads to causing tearing or other traumas to patient's incision of operator's manual traction in-process stability to take place, only allow line wheel 32 unidirectional rotation under mutually supporting between ratchet 354 and gag lever post 353, consequently, stay cord 33 rolling in-process, line wheel 32's rotation can not receive the restriction, and line wheel 32 can receive the restriction during antiport, thereby make operation in-process drag hook 29 can keep stable state.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
