The novel electronic aperture diameter measuring instrument according to claim 8, wherein a plurality of first latch teeth (453) are arranged on the inner side of the driving bevel gear (45), a first clamping block (452) matched with the first latch teeth (453) is rotatably connected to the driving shaft (43), a first clamping block groove (451) is formed in the driving shaft (43) at a position close to the first clamping block (452), a first return spring (454) is arranged in the first clamping block groove (451), and two ends of the first return spring (454) are respectively fixedly connected with the first clamping block (452) and the driving shaft (43).
10. The use method of the novel electronic aperture measuring instrument is characterized by comprising the following steps:
s1, holding the second shell (6) by hand, and enabling the driving motor (42) to rotate reversely through a motor switch;
s2, the driving shaft (43) drives the first clamping block (452) to rotate, and the first clamping block (452) is clamped with the first clamping tooth (453);
s3, the driving bevel gear (45) is driven to rotate, and then the driven bevel gear (63) is driven to rotate rapidly through meshing;
s4, the transmission shaft (61) drives the brush (7) to rotate rapidly, so that the inner wall of the circular hole can be cleaned;
s5, enabling the driving motor (42) to rotate forward through the motor switch;
s6, the meshing gear (44) drives the driven shell (46) to rotate through meshing, and the second clamping tooth (463) and the second clamping block (461) are clamped;
s7, the handle (1) is driven by the driven shell (46) to rotate, then the probe of the displacement sensor (3) on the guide body (2) is driven to cling to the inner wall of the round hole to rotate so as to obtain a plurality of data, and then the average value of the data is obtained through calculation to serve as the aperture of the round hole.
