[0018] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0019] like Figure 1-3As shown, the utility model is a compass-shaped scraper for making oil clay models, including a positioning needle 1, a positioning rod 2 is provided at the upper end of the positioning needle 1, and a handle 3 is connected to the top of the positioning rod 2. The positioning needle 1, the positioning rod 2 and the handle 3 are an integrally formed structure, and the side of the handle 3 can be provided with anti-slip grooves for easy holding. The positioning needle 1 can be inserted into the center of the oil clay by pulling the handle 3; a limiting nut 22 is sleeved on the bottom end of the positioning rod 2, and the handle 3 is connected to the positioning rod 2, and a fastening nut 21 is sleeved on the upper part of the positioning rod 2 through a thread, and the outer diameters of the limiting nut 22 and the fastening nut 21 are both larger than the slot width of the adjusting slot 61, and the limiting nut 22 is located at the bottom of the adjusting slot 61 for limiting, and the position of the L-shaped limiting piece can be limited by screwing the fastening nut 21; an L-shaped limiting piece 6 is sleeved on the positioning rod 2, and the surface of the positioning rod 2 is provided with threads, and the length of the positioning rod 2 is greater than or equal to the height of the L-shaped limiting piece 6, and the exposed length of the positioning rod 2 can be adjusted to Adjust the height of the L-shaped limiter 6; the upper side wall of the L-shaped limiter 6 is provided with a scale line 62, and the outer end of the L-shaped limiter 6 is connected to the transverse scraper 4. When the fastening nut 21 moves laterally along the adjustment groove 61, the distance between the right end of the transverse scraper 4 and the positioning pin 1 can be adjusted through the scale of the scale line 62, thereby adjusting the radius of the scraper sludge. The adjustment groove 61 is between the L-shaped limiter 6 and the transverse scraper 4, and the groove width of the adjustment groove 61 is slightly larger than the outer diameter of the positioning rod 2, which can ensure The positioning rod 2 can move laterally along the adjustment slot 61; the outer end of the transverse scraper 4 is connected to an arc scraper 5; the upper side surface of the L-shaped limiter 6 and the upper side surface of the transverse scraper 4 are parallel horizontal planes; the arc scraper 5 and the transverse scraper 4 are an integrally formed structure, and the arc scraper 5 and the transverse scraper 4 are carbon fiber plates.
