The specific embodiment
Below in conjunction with accompanying drawing, the utility model is done detailed explanation.
For the purpose, technical scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Shown in Fig. 1～7; This aperture is adjustable carpenter's reamer the comprises first cornish bit plate clamp 1, center of circle positioning element 2, reamer arm 3 and the second cornish bit plate clamp 4; Wherein center of circle fixed part 2 is fixed on the centre position of reamer arm 3; The first cornish bit plate clamp, 1 kink is at first end of reamer arm 3; The second cornish bit plate clamp, 4 kinks are at second end of reamer arm 3, and the bottom of center of circle positioning element 2 is location circular cone (being placed on the aperture of φ 1～3mm location), and the surface of location circular cone is provided with the size scale layer.Requiring reaming to have one when confirming the degree of depth, can at first realize any adjustment in reaming aperture through the first cornish bit plate clamp, confirm the reaming degree of depth through the size scale on the circular cone of location again.
