In through-hole, operation portion and mounting portion are equipped on the outside of described sleeve pipe component, and operating position is in the upside of mounting portion, the operation portion
It is equipped with operating handle, the mounting portion is equipped with external screw thread, sets that there are three threaded holes, and three spiral shells on the nut piece component
Pit is arranged on nut piece component in horizontal linear, and the nut piece component is mounted on mounting portion by threaded hole.
Preferably, the puncture main body outer upper is equipped with block, and punctures Your Majesty and be located at the setting of the part on the downside of block
In through-hole.
Preferably, the bottom for puncturing main body is processed as trigone needle construction.
Preferably, the section radius of the operation portion and the section radius of mounting portion are identical.
Preferably, the internal diameter of the threaded hole and the outer diameter of mounting portion are identical.
The utility model beneficial effect achieved is: the structure design of the utility model is reasonable, by using piercing assembly,
Sheath assembly and nut piece component triplicity design, drag hook can be played by carrying out assembling by sheath assembly and nut piece component
Effect, and drag hook one end can tune to any direction, the exposure of the more expedient surgical visual field, to accomplish to set about in small notch scope
Art, while more preferable exposure regards visual area, also to use the operations such as electric drill to provide good path, while three holes of nut piece are tied
Mounting portion, can be installed in any threaded hole of nut on piece by structure design as needed.
