Specific embodiment
Structure, ratio, size depicted in Figure of description etc., only to coordinate the content disclosed in description, with
Understand and read for those skilled in the art, be not limited to the enforceable qualificationss of this utility model, therefore do not have skill
Essential meaning in art, the modification of any structure, the change of proportionate relationship or the adjustment of size are not affecting this utility model institute
Under the effect that can be produced and the purpose that can reach, all should still fall what is can covered in the technology contents disclosed in this utility model
In the range of.Meanwhile, in this specification it is cited such as " on ", D score, "front", "rear", the term such as " centre ", be merely convenient to chat
That what is stated understands, and be not used to limit the enforceable scope of this utility model, and its relativeness is altered or modified, without substantive change
Under more technology contents, when being also considered as the enforceable category of this utility model.
As shown in Figure 1-Figure 3, a kind of nugget depth of cup measurement apparatus of this utility model, which includes main scale 1 and is arranged on
Vernier cursor 2 on main scale 1, the vernier cursor 2 can slide along main scale length direction, be equipped with standard quarter on main scale 1 and vernier cursor 2
Degree.The main scale 1 is provided with fixation measuring pawl 11, and the vernier cursor 2 is provided with movable measuring claw 21.The fixation measuring pawl 11
The first measurement head 12 is provided with, the movable measuring claw 21 is provided with the second measurement head 22, and first measurement head 12 and second is surveyed
Amount 22 is oppositely arranged, and the relative one end of first measurement head 12 and the second measurement head 22 is tip shape.When the vernier
When chi 2 slides, the end of the first measurement head 12 and the second measurement head 22 contacts.
