Fixed link 311 is gone up through threaded connection with second bolt 511 on one side, and the one end of second bolt 511 extends to fixed link 311 inside and tightly butt with slide bar 312, adopts this kind of design so that when the device needs carry out the centre gripping to the patient for a long time, accessible second bolt 511 locks to avoid medical personnel to trample the tired sense that brings for a long time.

Both sides of the supporting base plate 111 are arc-shaped, and fillets are arranged on the edge of the supporting base plate 111, so that the surface of the device is smoother by adopting the design.

The working principle is as follows: when the device is used, firstly, the supporting base plate 111 is placed above the operating table horizontally, then the supporting base plate 111 is moved to a proper position, the hand part of a patient can be placed in the supporting base plate 111, then the movable clamping plate 415 is rotated, the movable clamping plate 415 can move to one side close to the bed body when the movable clamping plate 415 is rotated, the first bolt 416 can be driven to move together when the movable clamping plate 415 moves, because the supporting base plate 111 is abutted against one side of the operating table, when the first bolt 416 is tightly abutted against the other side of the operating table, the movable clamping plate 415 can be stopped from rotating, the fixing of the supporting base plate 111 is completed, and then the operation can be performed on the patient.

When the limbs on both sides or one side of the operation site of the patient need to be clamped in the operation process, the pedal 325 is only needed to be stepped downwards, when the pedal 325 is stepped downwards, the sliding rod 312 is driven to move downwards, when the sliding rod 312 moves downwards, the sliding rod 312 drives the second rack bar 316 to move downwards, when the second rack bar 316 moves downwards, the second transmission gear 315 is driven to rotate anticlockwise, so that the first rotating shaft 314 rotates, when the first rotating shaft 314 rotates, the first belt pulley 317 is driven to rotate, so that the first transmission belt pulley 320 rotates and drives the second rotating shaft 318 to rotate, when the second rotating shaft 318 rotates, the third belt pulley 321 rotates, when the third belt pulley 321 rotates, the second transmission belt 323 rotates and drives the fourth belt pulley 322 to rotate, when the fourth belt pulley 322 rotates, the rotating shaft 217 rotates anticlockwise, when axis of rotation 217 anticlockwise rotation, because two sets of first rack boards 219 are in first drive gear 218 both sides respectively, thereby make two sets of first rack boards 219 be close to each other, can drive two sets of movable plates 211 when two sets of first rack boards 219 are close to each other and be close to each other, can drive two sets of bracing pieces 213 when two sets of movable plates 211 are close to each other and be close to each other, thereby make the grip block 216 of both sides respectively with the contact of patient limbs both sides, still can make second spring 223 take place deformation simultaneously when two sets of bracing pieces 213 remove, when the grip block 216 of both sides and the contact of patient limbs both sides, can make first spring 220 take place deformation, thereby keep the butt state, fix patient limbs, can perform the operation.

If the clamping state needs to be maintained for a long time, the second bolt 511 can be rotated, when the second bolt 511 is rotated, the second bolt 511 is enabled to be abutted against the sliding rod 312, so that the sliding rod 312 is limited, the clamping plate 216 is enabled to maintain the clamping state, and when the clamping state needs to be relieved, the second bolt 511 only needs to be rotated reversely, so that the second bolt 511 is enabled to be relieved from abutting.

When the clamping is required to be released, only the stepping on the pedal 325 needs to be released, and when the stepping is released, the third spring 324 and the second spring 223 can restore to deform together, so that the sliding rod 312 restores to the initial position, the second transmission gear 315 is driven to rotate clockwise, and meanwhile, the two groups of clamping plates 216 are far away from each other, and the clamping on the patient is released.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
