In engineering construction site, concrete slump tester (slump cone) is generally used to determine the slump of concrete. The structure of slump cone is described in Chinese patent CN201620930108.5. The cylinder needs to be fixed by a staff on the construction site to prevent displacement from the bottom plate. Generally, the ear plate at the bottom of the slump test cylinder is positioned by stepping on it with the foot, and then another staff member loads and inserts it.
