摘要: A measuring tape ( 150 ) having a pivoting catch 160 that rotates 172 about axis 159 ). rotational coupling assembly is secured to the distal end of tape. The pivotally assembled via pivot shaft 180 and lock assisting spring 188 oriented parallel registration interface such as pins 174 apertures 176, 177, 178 maintain in position. 360 degrees, can include at any angle, but preferably least 0, 90, 180, 270 degrees.
