Described horizontal extension axle by sleeve and the telescopic shaft that is set in respectively two ends, sleeve left and right form, sleeve center is provided with the through hole of vertical direction, described rotating shaft is located on horizontal extension axle by through hole activity; Scalable cutter shaft is made up of concentric interior axle and outer shaft, and described interior axle is sheathed in outer shaft movably, on outer shaft and interior axle, is respectively arranged with corresponding scale.
Salient point and the buckle of the coupling that described two rectangle bodies arrange respectively by the left and right sides fasten.
Compared with prior art, the utlity model has following beneficial effect:
(1) this device can the simple and convenient preparation that realizes efficiently circular wound model, and repeatability and controllability are strong, are beneficial to carrying out smoothly of follow-up experimentation;
(2) prepared circular wound model standardization is high, good stability is closer to actual requirement, little on edge of wound and the impact of wound base, man's activity to experimental index is little, has guaranteed accuracy, stability and the reliability of carrying out smoothly and testing of subsequent experimental and research;
(3) alternative high, can select voluntarily wound surface dimensions, Wound depth according to different experiment demands, range of application limitation is little;
(4) this apparatus structure is simple, less demanding to processing technology and experimental technique, and repeatability simple to operation is strong, and then greatly reduces scientific research cost.

The specific embodiment
Below in conjunction with the specific embodiment, this utility model is described in detail.
With reference to Fig. 1, Fig. 2, a kind of circular wound model device, comprise the cylinder 1 that is rolled the reducing being spliced into by two soft rectangle bodies, on the line of centres of described two rectangle bodies, be provided with horizontal extension axle 3, the central vertical of horizontal extension axle 3 wear penetrate can 360 ° of rotations rotating shaft 2, the top of rotating shaft 2 is stretched out cylinder 1 and is provided with handle 4, its underpart is provided with the scalable cutter shaft 5 of level, the end of scalable cutter shaft 5 is provided with blade 6, and blade 6 can be connected with the end of scalable cutter shaft 5 up and downly.
The double-edged blade that this utility model preferred blade 6 is handstand triangle, has scale on it, the knife edge is positioned at drift angle both sides, and its scale is initial from point of a knife place to be arranged to the knife back.
