It refers to the materials and equipment used, and the technical activities such as survey, design, construction, maintenance, and repair carried out, as well as the object of engineering construction, that is, whether it is built above or below the ground, on land or in water. Construction project quality inspection refers to the activities of testing the materials, components, equipment, and the quality and use functions of the construction project to determine its quality characteristics in accordance with relevant national laws, regulations, mandatory standards for engineering construction and design documents. It includes: testing of structural safety; testing and determining the physical properties of building materials; testing and analyzing the durability of building materials; and other methods or measures as needed and necessary. The percussion hammer is a percussion tool used to detect whether the quality of each project of the construction project meets the national standards after the completion of the construction project.

[0014] 2. The shock-absorbing percussion hammer for civil engineering quality inspection can illuminate the building to be inspected by turning on the switch of the lighting lamp when used in a poor light environment through the setting of the lighting mechanism, so as to facilitate the workers to perform percussion inspection. The setting of the clamp and the positioning block facilitates the installation of the lighting lamp, and it is also convenient to disassemble and store when not in use;

[0015] 3. A shock-absorbing percussion hammer for civil engineering quality inspection, through the setting of a fixed block, a threaded rod, a connecting rod, a turning handle, a telescopic rod and a limit rod, can drive the threaded rod to rotate by turning the turning handle, thereby driving the telescopic rod to extend out of the inside of the sleeve rod, so that the extension length of the telescopic rod can be adjusted according to the inspection height. The setting of the limit rod can limit the telescopic rod to prevent the telescopic rod from idling inside the sleeve rod. BRIEF DESCRIPTION OF THE DRAWINGS
