More advantageously, a plurality of mounting holes 9 are formed in the first reference seat 11, and the reference ruler 21 can be adjusted in mounting position according to different special-shaped punches 7, for example: for the special-shaped punch 7 with the larger special-shaped punch cutting edge 73, the larger the angle of rotation of the detection ruler 22 is, at this time, the angle dial 23 can be far away from the first reference seat 11 by adjusting the positions of the installation holes of the reference ruler 21 and the first reference seat 11, so that the detection ruler 22 can be better attached to the edge of the special-shaped punch cutting edge 73. In order to more securely mount the reference scale 21 on the first reference base 11, a mounting groove 4 may be provided on the first reference base 11, and one end of the reference scale 21 may be disposed in the mounting groove 4, while the reference scale 21 and the first reference base 11 are detachably connected by a screw 8.

In order to avoid measurement errors due to a weak grip on the profiled punch body 72, in some embodiments, the cavity 6 may extend through the second reference block 12. The bottom of the second reference seat 12 is provided with a cushion block 5 for supporting the special-shaped punch body 72, it should be understood that the shape of the cushion block 5 is adapted to the shape of the chamber 6, the thickness of the cushion block 5 can be set according to the length of the special-shaped punch body 72, and the main function of the cushion block is to adjust the height of the special-shaped punch cutting edge 73, so that the special-shaped punch cutting edge 73 can adapt to the height of the detection ruler 22, and meanwhile, the positioning pin 31 can be aligned with the positioning groove 71 on the special-shaped punch body 72 by adjusting the thickness of the cushion block 5. For example, when the shaped punch body 72 is long, the cushion block 5 with a small thickness may be selected or the cushion block 5 may not be configured; when special-shaped drift main part 72 was short, special-shaped drift blade height was low on the low side, and when the measuring tape was unable to laminate mutually with the edge of special-shaped drift blade, the great cushion 5 of thickness can be chooseed for use. Therefore, by providing the spacer 5 at the bottom of the chamber 6, it is possible to support the shaped punch body 72 to adjust the height of the shaped punch body 72 within the chamber 6. In order to further stabilize the special-shaped punch body 72, one side, away from the positioning mechanism 3, of the cross section of the cavity 6 is in an inverted V shape, the special-shaped punch body 72 can form two trimming edges with the V-shaped edge of the cavity 6, meanwhile, the cushion block 5 is arranged at the bottom of the special-shaped punch body 72, so that three stress positions are formed between the special-shaped punch body 72 and the cushion block 5 and between the V-shaped edge of the cavity 6, when the positioning pin 31 is fastened to the positioning groove 71, the special-shaped punch body 72 can be more stably fixed on the detection tool through the three stress positions, the special-shaped punch 7 is prevented from inclining, and the cutting edge angle detection mechanism 2 can accurately measure the cutting edge angle of the special-shaped punch 7. It should be understood, however, that the shape of the chamber 6 of the present invention is not limited to the specific examples described above, such as: the shape of the chamber 6 can also be set to be a right angle shape as long as the positioning pin 31 can be positioned to the positioning groove 71 preset by the special-shaped punch 7, and the positioning of the special-shaped punch 7 is realized.
