Be further used as the improvement of technical solutions of the utility model, described first calvus and the second calvus all formed the tip of lateral bend in described angle.
Be further used as the improvement of technical solutions of the utility model, described first draft arm and the second draft arm are equipped with axis hole, described first draft arm and the second draft arm are all contained on described back shaft by described axis hole, and the described first draft arm upper shaft hole center of circle equals the distance of the described second draft arm upper shaft hole center of circle to the second calvus tip to the distance at the first calvus tip.
Be further used as the improvement of technical solutions of the utility model, described governor motion comprises adjusting rod, and described first draft arm and the second draft arm are equipped with the fixed block that can clamp described adjusting rod.
Be further used as the improvement of technical solutions of the utility model, described fixed block is provided with the through hole passed for described adjusting rod, and described fixed block is by being contained on described first draft arm and the second draft arm perpendicular to the connection rotating shaft of described through hole.
Be further used as the improvement of technical solutions of the utility model, described back shaft is provided with external screw thread, and described back shaft is provided with the nut regulating described first draft arm and the second draft arm position on back shaft.
Be further used as the improvement of technical solutions of the utility model, described support the tip of the axis is provided with contiguous block, and described contiguous block is provided with fixing hole, is provided with nail through described fixing hole.
Be further used as the improvement of technical solutions of the utility model, described first calvus and the first draft arm, the second calvus and the second draft arm are and removably connect.
The beneficial effects of the utility model: when this skin wound repairs traction apparatus use, adjust the angle between the first draft arm and the second draft arm, first calvus and the second calvus are grabbed the skin surface investing wound surface both sides respectively, then constantly the angle between the first draft arm and the second draft arm is reduced under the effect of governor motion, thus cover skin injury district gradually by the soft tissue that stretching regenerates, this utility model structure is simple, uses, easy to carry.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is this utility model embodiment axonometric drawing;
Fig. 2 is this utility model embodiment front view;
Fig. 3 is this utility model embodiment side view.
Detailed description of the invention
Referring to figs. 1 through Fig. 3, that show the concrete structure of the preferred embodiment of this utility model.The construction features of each element of this utility model will be described in detail below, if and when being described to direction (upper and lower, left and right, before and after), be be shown structure for reference to describing with Fig. 1, but actual user of the present utility model is to not limiting to so.
This utility model provides a kind of skin wound and repairs traction apparatus, comprise back shaft 1 and rotating the first draft arm 2 and the second draft arm 3 be contained on described back shaft 1, described first draft arm 2 and the second draft arm 3 are equipped with axis hole, described first draft arm 2 and the second draft arm 3 are all contained on described back shaft 1 by described axis hole, angle is formed between described first draft arm 2 and the second draft arm 3, described first draft arm 2 bottom is provided with the first calvus 4, the bottom of described second draft arm 3 is equipped with the second calvus 5, described first calvus 4 and the first draft arm 2, second calvus 5 and the second draft arm 3 are and removably connect, first calvus 4 and the second calvus 5 adopt dismountable syndeton, length and width can need to arrange flexibly according to use.Described first calvus 4 and the second calvus 5 are all formed the tip of lateral bend in described angle, the first calvus 4 and the second calvus 5 by most advanced and sophisticated can grab attached live the skin of wound surface both sides.The described first draft arm 2 upper shaft hole center of circle equals the distance of the described second draft arm 3 upper shaft hole center of circle to the second calvus 5 tip to the distance at the first calvus 4 tip.The governor motion of corner dimension described in adjustable is housed between described first draft arm 2 and the second draft arm 3.Described governor motion comprises adjusting rod 6, and described first draft arm 2 and the second draft arm 3 are equipped with the fixed block 7 that can clamp described adjusting rod 6.Described fixed block 7 is provided with the through hole passed for described adjusting rod 6, and described fixed block 7 is contained on described first draft arm 2 and the second draft arm 3 by the connection rotating shaft 71 perpendicular to described through hole.
