背景技术Background technique
现今的指针式仪表，都有一个实体的指针，但由于转动惯量与实体指针的长度呈现平方的关系，因此实体指针不能做的太长，从而不可能使电流表的刻度盘的尺寸范围做大，较短指针仪表在教学演示中，不能使的离仪表稍远的学员直接观看到仪表的指示值。Today's pointer instruments all have a solid pointer, but since the moment of inertia and the length of the solid pointer are in a square relationship, the solid pointer cannot be made too long, so it is impossible to make the size range of the ammeter dial larger. In the teaching demonstration of the short pointer meter, the students who are far away from the meter cannot directly view the indicated value of the meter.
发明内容SUMMARY OF THE INVENTION

The beam expander and the laser module can adopt a separate structure or All-in-one structure.
在刻度盘上表面设置有弧形遮光条，弧形遮光条的下沿边距离刻度盘的上表面有一定的高度，弧形遮光条的弧线中心与偏转机构转的中轴线重合。An arc shading strip is arranged on the upper surface of the dial, the lower edge of the arc shading strip is a certain height from the upper surface of the dial, and the arc center of the arc shading strip coincides with the central axis of the deflection mechanism.
