It is threaded with nut, the nut and drawing pedestal inner end rotation connection.
Further, there is axial guide groove on the screw rod, pull and be equipped on pedestal in insertion guide groove
Guide pin prevents screw rod from generating rotation by guide pin effect.
The drawing pedestal inner end has the cavity with nut clearance fit, and nut periphery offers circumferential recess,
Position-limitting pin is installed into the circumferential recess from drawing pedestal inner end, is acted on by position-limitting pin so that nut can only turn
Axial movement that is dynamic and limiting nut.
To simplify structure, there is the card slot for being caught in the connecting rod on the drawing pedestal, drawing pedestal equipped with from
The clamping screw of card slot clamping sides connecting rod.
Drawing steel wire is adjusted for convenience of replacement, the drawing steel wire is pressed on fixed pedestal by lock screw.
The beneficial effects of the utility model are: the utility model can make full use of the internal space of exterior fixing rack, locating
While reason fracture the problem of processing defect of skin, cooperated by the transmission between screw rod, nut, flexible modulation skin traction device
Position to adapt to wound shape, during skin traction, for the irregular of wound, be closed in advance when apart from small wound
Afterwards, the drawing steel wire of the closure surface of a wound can individually be extracted out, and the not closed surface of a wound can further be drawn, and in wound side
Skin adjust it is bad in the case where remain to using the good side of edge of wound skin can also be pulled individually to reduce or be closed wound
Face.

Specific embodiment
The utility model is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram,
Only illustrate the basic structure of the utility model in a schematic way, therefore it only shows composition related with the utility model.
One kind as shown in FIG. 1 to 3 is based on the matched skin traction device of exterior fixing rack institute, the exterior fixing rack 1
Including setting up the connecting rod 1-1 of two sides separately and being connected to the cross bar of connecting rod 1-1 upper and lower side.
The skin traction device includes: the drawing pedestal 2 that can be clamped on the connecting rod 1-1 of exterior fixing rack 1, for installing
The fixed pedestal 4 of steel wire 3 is pulled, there is the card slot 2-1 for being caught in the connecting rod 1-1 on drawing pedestal 2 therein, pull pedestal
2 are equipped with the clamping screw 9 from card slot 2-1 clamping sides connecting rod 1-1, and the drawing steel wire 3 with protective case passes through locking screw
Silk 10 is pressed on fixed pedestal 4.
The drawing pedestal 2 has axial inner hole, and 2 inner end of drawing pedestal of nearly 4 side of fixed pedestal has one
A diameter is greater than the cavity of inner hole, is equipped with one end in the inner hole of drawing pedestal 2 and is pierced by the cavity and passes through with fixed pedestal 4
The connected screw rod 5 of pin, drawing 2 inner end side of pedestal are equipped with the nut 6 being threadedly coupled with screw rod 5, and nut 6 has one knot
The rotation section of structure and limiting section, wherein the cavity gap of the limiting section of nut 6 and drawing 2 inner end of pedestal cooperates.
Particularly, the limiting section periphery of nut 6 offers circumferential recess 6-1, from 2 inner end of pedestal is pulled to the circumferential direction
The position-limitting pin 8 that the restricted nut 6 of installation moves axially in groove 6-1；Similarly, there is axial lead on the screw rod 5
To slot 5-1, pull the guide pin 7 being equipped in insertion guide groove 5-1 on pedestal 2, by the effect of guide pin 7 prevent screw rod 5 with
Nut 6 generates rotation phenomenon when cooperating and moving, and position-limitting pin 8 then prevents from generating axial movement when the rotation of nut 6.
In use, the lock screw 10 of drawing steel wire 3 by drawing in wound skin is pressed abd fixed on fixed pedestal 4,
Rotating nut 6 makes screw rod 5 move axially to suitable position, and the connecting rod 1-1 of exterior fixing rack 1 is caught on drawing pedestal 2
In card slot 2-1, with clamping screw 9 from clamping sides connecting rod 1-1, when skin drawing slowly restores for a period of time, then
It is moved to next suitable drawing position by 6 adjusting screw rod 5 of nut, continues that skin pull until recovery from illness.If
Tractor need to axially make adjustment up and down along connecting rod 1-1 during skin drawing, need only unclamp clamping screw 9, will pull
Pedestal 2 axially makees moving for certain distance along connecting rod 1-1, tightens clamping screw 9 again after movement in place.
The utility model can cooperate by the transmission between screw rod 5 and nut 6 and pull base according to the shape of wound
Seat 2 is moved axially along connecting rod 1-1, realizes the position of flexible modulation skin traction device to adapt to wound shape；It is led in skin
During drawing, for the irregular of wound, after being closed in advance apart from small wound, the drawing of the closure surface of a wound can be individually extracted out
Steel wire 3, and the remaining not closed surface of a wound can further be drawn, and still in the case where wound side skin adjusts bad
It can use, the good side of edge of wound skin can be pulled individually to reduce or be closed the surface of a wound.It should be mating based on exterior fixing rack 1
Skin traction device can make full use of the internal space of exterior fixing rack 1, processing defect of skin asks while handling fracture
Topic.
It is enlightenment, through the above description, related work people with the above-mentioned desirable embodiment according to the utility model
Member can carry out various changes and amendments in the range of without departing from this item utility model technical idea completely.This item is real
