ABSTRACT:
A soft stop-proof hook head of a measure tape is located at one end of the measure tape and comprises a ruler hook. A surface of a ruler hook is enclosed by a soft elastomer. The soft elastomer is made of a flexible material. When the soft elastomer is pressed, it generates an elastic resistance; in measuring, the ruler hook is coupled to a measured bench mark of an object to be measured with a slide-stop effect. Moreover, the soft elastomer is extended with a slide piece for enhancing the slide-stop effect.
