211 be spherical structure, and test side 211 with blind way for contacting.
Sensing device 30 includes multiple induction pieces 31, and the number of induction pieces 31 is equal with the number of detection piece 21, institute's thoughts
Being arranged in the slideway of the second pedestal 14 of 31 rectangular array of part is answered, induction pieces 31 can slide vertically with respect to the second pedestal 14, sense
Part 31 and the second pedestal 14 are answered to be equipped with reset spring 126, reset spring 126, which has, pushes induction pieces 31 to move vertically downwards
Trend.All induction pieces 31 form the multiple rows of of rectangular array distribution, and the length of the induction pieces 31 in adjacent two rows differs, close
The length of induction pieces 31 in one row of the first pedestal 13 is less than the length of the induction pieces 31 in the row far from the first pedestal 13.
Induction pieces 31 are rod piece, and induction pieces 31 have an induction end 311, induction end 311 through the second pedestal 14 top and be located at the
The outside of two pedestals 14, test side 211 are equipped with top plate 312, and top plate 312 is rectangular slab, when the induction end of all induction pieces 31
311 when being generally aligned in the same plane in 4122, and all top plates 312 constitute a complete rectangular slab.
Transmission mechanism 40 includes multiple gear units 41, and a detection piece 21 and an induction pieces 31 are single by a transmission
Member 41 connects.
As shown in fig. 7, gear unit 41 includes shaft 411, driving wheel 412, gear 413 and rack gear 414.Shaft 411 can
Rotation is set to the second pedestal 14, and 411 lateral arrangement of shaft, i.e., shaft 411 is perpendicular to detection piece 21 and induction pieces 31；Driving
Wheel 412 is fixed on one end of shaft 411, and gear 413 is fixed on the other end of shaft 411；Rack gear 414 is vertically arranged, and fixed
In on detection piece 21, gear 413 is engaged with rack gear 414；The one end of induction pieces 31 far from induction end 311 and 412 circumferential surface of driving wheel
Contact.
