Description

Technical Field

[0001] The utility model relates to the technical field of geological hammers, in particular to a telescopic geological hammer. Background Art

[0002] Geology refers to the nature and characteristics of the earth, mainly referring to the material composition, structure, construction, and development history of the earth, including the differentiation of the earth's spheres, physical properties, chemical properties, rock properties, mineral composition, the output status of rock strata and rock bodies, contact relationships, the earth's tectonic development history, biological evolution history, climate change history, as well as the occurrence and distribution patterns of mineral resources. For geologists, geological hammers are one of the basic tools for geological work. They are made of high-quality steel, and their styles vary with the rock properties of the working area. Most geological hammers used in igneous rock areas have a rectangular or square end and a pointed or wedge-shaped end. Those used in areas with developed sedimentary rocks often have a crane's beak at one end. Geological hammers are also divided into light and heavy types according to weight.

[0003] For example, Chinese patent publication number CN208342759U discloses a geological hammer, which includes a hammer head, a hammer handle, a rubber sleeve and a spring. The beneficial effect of the utility model is that the setting of the rubber sleeve can prevent the hammer head body from falling off due to excessive stress. The setting of the spring can, on the one hand, prevent the hammer head from flying to other places when the connection between the hammer head and the hammer handle falls off due to excessive stress. On the other hand, the elasticity of the spring can absorb the impact force of the hammer head and buffer the force when the hammer head flies out, thereby preventing damage to the user himself.

[0004] However, in the above scheme, the geological hammer has a relatively simple functionality, with only a striking function. It is not convenient to extend or reinforce the hammer handle, and it is not convenient to measure the length of an object. It is not very convenient and has low applicability. Utility Model Content
