[0002] The geological hammer is one of the basic tools for geological work. It is made of high-quality steel. Its style varies with the nature of the rocks in the working area. One end of the geological hammer is rectangular or square, and the other end is sharp or wedge-shaped. When in use, the square end is generally used to hit the rock to break it into pieces; the sharp edge or flat wedge-shaped end is used to hit along the rock layer to peel off the rock layer, which is conducive to finding fossils and sampling; it is also used to repair rock, ore and other specimens to standardize them for easy packaging.

[0003] However, the existing geological hammers used for field geological exploration generally lack energy absorption mechanism in the hammer handle design, which greatly affects the safety and comfort of its use. Specifically, the hammer handle of the traditional geological hammer is usually made of hard material and lacks the necessary energy absorption and buffering design. When hitting rocks or other hard objects, the impact force directly acts on the hammer handle, and the user's hand is prone to feel strong vibration and impact. Long-term use may even cause hand fatigue or injury. Therefore, we need to propose a foldable geological hammer for field geological exploration. Utility Model Content
