Embodiment Construction
[0032] Below in conjunction with accompanying drawing and embodiment the present invention is described in detail:
[0033] Such as Figure 2 to Figure 5 As shown, the vernier caliper of the present invention that can effectively reduce the Abbe error includes a main ruler 1 and a vernier ruler 2. The upper and lower ends of the front side of the vernier ruler 2 are formed with flanges to form a main ruler accommodating groove 3. The main ruler 1 is set in the main scale accommodating groove 3 and the vernier scale 2 is slidably connected with the main scale 1. The above-mentioned structure is a conventional structure of the existing vernier caliper and will not be repeated here.
[0034] In the present invention, pressure sensing devices are arranged symmetrically along the front and rear directions in the main ruler accommodating grooves 3 at the upper and lower ends, and the pressure sensing devices are used to collect the pressure signals generated by the main ruler 1 and ...
