Embodiment
To make the technical means, creative features, achievable purpose and effectiveness that the utility model is realized easy to understand, below
With reference to embodiment, the utility model is expanded on further.
Please refer to Fig.1 to Fig.3, the utility model includes protractor 1, clamping piece and locating piece, and the surface of protractor 1 is carved
Distance scale is carved with angled scale, the bottom of protractor 1, and the centre position of protractor 1 is provided with handle 11.
The centre of handle 11 is provided with straight slot 12, and clamping piece is installed in straight slot 12, by connecting rod 21, is arranged on connecting rod 21
The middle clamp 24 of left end, the upper clamp 22 for being arranged on the middle top of clamp 24 and the lower clamp 23 for being arranged on the middle lower section of clamp 24
Form, middle clamp 24 is major arc shape, and end connects upper clamp 22 and lower clamp 23 respectively, and three is made of elastic material, structure
Into a grip unit, pinch upper clamp 22 and 23 end of lower clamp can increase in clamp 24 space, it is convenient to place chalk, company
The outer surface of extension bar 21 is engaged, even with internal thread with external screw thread, the inner surface of straight slot 12 by internal thread with external screw thread
