the handle pressing part 8 comprises a strip-shaped sliding opening 801, the right side of the front end face of the handle pressing part 8 is provided with the strip-shaped sliding opening 801, the strip-shaped sliding opening 801 is connected with a driving column on the T-shaped sliding block 701 in a sliding mode, and when a handle at the left end of the handle pressing part 8 is pressed downwards, the strip-shaped sliding opening 801 can drive the driving column on the T-shaped sliding block 701 to move downwards in a straight line; spacing plug connector 9 includes square slider 901 and T type inserted bar 902, spacing plug connector 9 is shell structure, and the inside sliding connection of spacing plug connector 9 has square slider 901, square slider 901 middle part fixedly connected with T type inserted bar 902, and T type inserted bar 902 outside is located the inside spring that has cup jointed of spacing plug connector 9, T type inserted bar 902 lower extreme is pegged graft in spacing jack on supporting shoe 4, setting through spacing plug connector 9, make revolving stage 10 can obtain effective limiting displacement, when needs rotate revolving stage 10 one hundred eighty degrees, through manual pulling upwards T type inserted bar 902, make T type inserted bar 902 lower extreme extract in the spacing jack on supporting shoe 4, then rotate one hundred eighty degrees after, it can in another spacing jack on supporting shoe 4 to insert T type inserted bar 902 lower extreme again.

Wherein, fixed establishment 2 includes connecting block 201, rectangle slide bar 202, splint 203 and fastening screw 204, connecting block 201 right-hand member is equipped with rectangle slide bar 202, and threaded through hole has been seted up at connecting block 201 up end left side middle part, connecting block 201 is connected with fastening screw 204 through threaded through hole, and fastening screw 204 lower extreme rotates and is connected with splint 203, splint 203 up end left side is the symmetry form around and is equipped with two spacing slide bars with connecting block 201 sliding connection, rectangle slide bar 202 slides with rectangle slide cartridge 101 and is connected, fastening screw 204 upper end is equipped with the rotation hand wheel, and it is equipped with two supplementary bull sticks to rotate hand wheel outer peripheral face lower part on fastening screw 204 and be the annular array form, thereby save effort more when making fastening screw 204 fasten.

Wherein, when cushion 3 is in the mounted state with bottom plate 1, cushion 3 bottom T type spout respectively with bottom plate 1 on the T type draw runner slide connection, and two elastic buckle 303 and a limiting plate 102 on the rectangle bayonet socket looks joint, thereby make cushion 3 can obtain effective limiting displacement on bottom plate 1, and through pinching two elastic buckle 303 to relative direction, make cushion 3 lose limiting displacement on bottom plate 1, then can pull down cushion 3 from bottom plate 1 fast, and then improved the convenience of cushion 3 when carrying out the cleaning and dismantling work greatly.

When in use: firstly, a base plate 1 is placed on the upper end face, located at the leg part of a human body, of an operating table, then a first fastening bolt 103 is loosened manually, so that a rectangular sliding rod 202 loses a fastening effect inside the rectangular sliding rod 202, then a connecting block 201 is flexibly adjusted according to the width of the operating table, the first fastening bolt 103 is screwed after the adjustment is completed, then a fastening screw 204 is rotated manually, the fastening screw 204 drives a clamping plate 203 to move upwards under the action of threads, and the bedside of the operating table is clamped through the clamping plate 203 and the connecting block 201, so that the drilling device can be effectively fixed on the operating table;

when the legs of a patient are fixed, the legs of the patient are firstly placed on the upper part of the spongy cushion 301, then the distance between the two arc-shaped clamping plates 603 is adjusted according to the requirement, when the adjustment is carried out, the adjusting screw 604 is rotated to enable the two adjusting slide blocks 601 to move towards the opposite direction or the opposite direction under the action of two reverse threads outside the adjusting screw 604, so that the distance between the two arc-shaped clamping plates 603 is flexibly adjusted, then the clamping screw 602 is manually rotated to enable the clamping screw 602 to drive the arc-shaped clamping plates 603 to move linearly downwards under the action of the threads, then the legs of the patient are clamped and fixed on the upper part of the spongy cushion 301 through the spongy clamping cushion at the bottom of the arc-shaped clamping plates 603, so that the legs of the patient are effectively fixed, when the holes are drilled, only the dynamic pressure handle piece 8 needs to be pressed downwards, the electric drill device 7 can move downwards to drill holes, and the drilling can be completed without the electric drill device 7 being held by a doctor, the accuracy of the drilling device in drilling is greatly improved;

during drilling, press 8 left end handles of handle spare when pushing down, drive the downward rectilinear movement of post on the drive T type slider 701 through bar sliding opening 801, thereby make T type slider 701 slide down on two spacing guide arms 702, and compress down the outside spring that cup joints of two spacing guide arms 702, then drive electric drill device 7 rectilinear movement downwards through T type slider 701, rethread electric drill device 7 drill bit carry out drilling operation to patient's shank skeleton can, because press and be connected through the pivot rotation between 8 right-hand members of handle spare and the L type slide 703 up end, make and press handle spare 8 to form lever structure, thereby make electric drill device 7 save more laborsaving when pushing down the operation, and then greatly reduced the loss of the labour dynamics when this drilling equipment uses.
