Therefore, because the processing tool is worn during use, the depth of the blind hole 201 is very easy to be smaller than the preset depth after the blind hole 201 is processed by the processing tool. Referring to fig. 10A and 10B, if the depth of the blind hole 201 does not meet the standard, the detecting element 232 is driven by the second driving element 223 to rotate and collide with the sidewall of the blind hole 201, the detecting element 232 fails to drive the rotating element 233 to rotate to the detecting position, and the light emitted by the sensor 234 is not shielded by the rotating element 233 at this time, so that it can be determined that the depth of the blind hole 201 meets the predetermined depth; referring to fig. 11A and 11B, if the depth dimension of the blind hole 201 meets the standard, the detecting element 232 is driven by the second driving element 223 to rotate, the detecting element 232 does not collide with the sidewall of the blind hole 201, the detecting element 232 can drive the rotating element 233 to rotate to the detecting position, and at this time, the light emitted by the sensor 234 is shielded by the rotating element 233, so that it can be determined that the depth dimension of the blind hole 201 meets the predetermined depth dimension.

Two shielding portions 2333 are further disposed between the first and second limiting grooves 2331 and 2332, and the two shielding portions 2333 are spaced apart to shield the light emitted from the sensor 234.
