[0003] During the patent application process, a search revealed a Chinese patent with patent number CN213577525U: a device for testing the surface hardness of building materials. The device includes a supporting base plate, with slide rails on both sides of the top of the base plate. Two sliding strips are slidably connected to the top of each slide rail. A base is located on one side of the top of the base plate, and a support column is mounted on the top of the base. A telescopic sleeve is mounted on the top of the support column, and a telescopic rod is fitted onto the top of the telescopic sleeve.
