Abstract
Abstract An improved stopping device for a measuring tape in a tape ruler over known tape rulers, which is structured and operates with only a simple pressing button, whereas conventional tape rulers have several parts. A pressing button 3 with an empty cavity 4, movable friction stopper 5, slit 6, protruding core bar 7, and coil spring separately form the ruler with a measuring tape 2 which is taken into the cavity through the slit and the spring is placed on the spring base plate 9. The measuring tape 2 can be stopped by the two stoppers, or released by pressing the pressing button 3.
