[ detailed description ] embodiments

As shown in fig. 1-2, in order to comply with the present invention, a testing fixture 100 is provided, which can be used to assist a three-dimensional measuring instrument to measure the size of a touch pen core 200.

The testing jig 100 comprises a base 10, wherein the base 10 is provided with a horizontal plane 101, and a groove 110 for placing the stylus pen core 200 is formed in the base 10 from the horizontal plane 101 in a concave manner, the shape of the groove 110 is matched with that of the stylus pen core 200, and the stylus pen core 200 and the groove 110 can be mutually matched in a positioning manner.

The test fixture 100 is made of metal material. The test fixture 100 further includes a reference surface 102 that can be placed on the three-dimensional measuring instrument, and a pair of connecting surfaces 103 that connect the horizontal surface 101 and the reference surface 102. The reference plane 102 and the horizontal plane 101 are parallel to each other. A pair of the connection surfaces 103 are parallel to each other and perpendicular to the horizontal surface 101. The test fixture 100 may have a rectangular parallelepiped shape or a cubic shape. Specifically, the utility model discloses a test fixture 100 is the cuboid form, and its cross sectional shape is the square. The horizontal surface 101, the reference surface 102, and the pair of connection surfaces 103 are all provided on a rectangular surface of the rectangular parallelepiped.

The direction of the groove 110 along the length of the stylus pen core 200 is the length direction of the groove 110. The length direction of the groove 110 is perpendicular to the connecting surface 103. The stylus pen core 200 comprises a pen head 210 and a pen holder 220 connected with the pen head 210. The barrel 220 includes a first end 221 distal from the tip 210. The groove 110 includes a first end 111 engaged with the first end 221 of the stylus cartridge 200 and a second end 112 opposite to the first end 111. A pair of said connection faces 103 comprises a first connection face 113 near said first end 111 and a second connection face 123 opposite said first connection face 113. The second end portion 112 penetrates the second connection surface 123, and the first end portion 111 does not penetrate the first connection surface 113. The first end 111 of the groove 110 is provided with an alignment surface 114, and the end of the first end 221 of the stylus pen core 200 is provided with an end surface 224 which can abut against the alignment surface 114. The alignment surface 114 is perpendicular to the horizontal surface 101 and perpendicular to the length direction of the groove 110. After the stylus pen core 200 is positioned in the groove 110, the length of the stylus pen core is measured by taking the alignment surface 114 as a measurement reference. The length of the groove 110 is smaller than that of the stylus pen core 200, so that after the stylus pen core 200 is positioned in the groove 110, the pen point 210 of the stylus pen core 200 is positioned outside the groove 110, and the stylus pen core 200 is conveniently positioned in the groove 110 or taken out of the groove 110.
