When the switch is operated, a driver usually stretches the first section and the second section of the front end of the finger into the operation space of the switch to operate, the fixed check digital model only needs to manufacture the first section and the second section of the finger, wherein the connecting line of the point B, A is the first phalange of the finger, the A, C connecting line is the second phalange of the finger, the front end of the first phalange is also provided with a semicircular pure meat front end, the outer side contour of the semicircular pure meat front end is obtained by rounding the first section in the reference plane according to a preset radius by taking the point B as the center, in addition, the first preset distance, the second preset distance and the third preset distance are the width of the phalange joint, the first contour and the second contour of the isosceles trapezoid are certainly included by taking the width as the upper bottom and the lower bottom, the outer contour line of the circle and the first contour is selected to obtain a third contour, namely the contour actually comprising the outer contour of the first section of the front end of the finger, the second contour is wound around the auxiliary contour, and finally the first contour is obtained by winding the auxiliary contour around the first nucleolus, and the first contour is obtained by winding the first contour around the first nucleolus, and the outer contour of the first nucleolus is corrected to obtain the contour which is positioned at the front of the first section. In addition, the first preset distance is 8 to 14 mm, the second preset distance is 15 to 20 mm, the third preset distance is 18 to 24 mm, the preset radius is consistent with the first preset distance, and the length of the connecting line of B, A is 15 to 23 mm. A. The length of the connecting line of C is 20 to 30 mm.

In addition, the step of checking the digital-analog of the switch to be checked through the checking surface comprises the following steps: shifting the checking surface outwards by a preset distance to obtain a theoretical checking surface; judging whether the theoretical checking surface interferes with the digital-analog of the switch to be checked; if yes, the operation space of the digital-analog switch to be checked is insufficient; if not, the operation space of the switch digital-analog to be checked is enough
Further, the step of obtaining a plurality of auxiliary curves through the first calibration volume and the second calibration volume according to a preset rule includes: setting a line passing through the point B and parallel to the Y axis as a rotation axis; rotating the first nuclear correcting body around the rotating shaft to a preset angle in the negative Z-axis direction; acquiring a first intersection line of the outer surfaces of the first nuclear correction body and the second nuclear correction body, and setting an intersection point of the first intersection line and the reference surface as an auxiliary point; moving the first check body and the second check body to the digital-analog of the switch to be checked so as to enable the auxiliary point to coincide with the datum point; setting an intersection line of the first calibration body and a reference plane as the auxiliary curve; and continuously executing the step of rotating the first nuclear correcting body around the rotating shaft to a preset angle in the negative Z-axis direction for preset times, and sequentially obtaining a plurality of auxiliary curves.

The method comprises the steps of obtaining a plurality of auxiliary curves by adjusting the rotation angle of a finger, obtaining the auxiliary curves by making tangents of spline lines and the auxiliary curves, forming the spline lines, namely checking curves by the positions of the points, namely stretching the checking curves to two sides, obtaining theoretical checking surfaces by shifting the checking surfaces to the outer sides by a preset distance, and checking by the theoretical checking surfaces to further ensure the successful checking space, wherein the errors caused by insufficient rotation angle step times are reasonably covered. Whether the operation space is reasonable can be judged by whether the switch digital modulus interferes with the theoretical checking surface. The theoretical checking surface stretches to the two sides by half the width of the finger. In addition, different switch operation space checking methods are consistent with the method, the only difference is that when the switch is used, a plurality of fingers are used for operation, theoretical checking surfaces in different numbers of positions are made through the difference of hand indexes, and the switch digital-analog is not interfered with any theoretical checking surface, namely the operation space is reasonable in design.
