Title: Breaker hammer for breaking hard objects

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to hammers and more particularly, to a breaker hammer for breaking hard objects. 
     2. Description of the Related Art 
     The general hammer usually has a flat striking surface. The force generated by swinging the hammer allows the striking surface to strike or impact the object, such as nails, or to make the surface of the object impact the desired shape and structure. 
     However, if the object to be struck by the hammer is a relatively hard material, it often happens that even if the weight of the hammer or the force of swinging the hammer is increased, the hard object cannot be effectively broken. 
     SUMMARY OF THE INVENTION 
     The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a breaker hammer, which can effectively strike and break hard objects in addition to its general use. 
     To achieve this and other objects of the present invention, a breaker hammer for breaking hard objects comprises at least one striking face. One striking face comprises a breaking portion inside. The breaking portion occupies about 80% of the area of the respective striking face. The breaking portion comprises at least two striking areas protruding from the respective striking face, thereby effectively striking and breaking hard objects. 
     Preferably, the breaking portion is a concentric circle area retracted a predetermined distance from a ring edge of the respective striking face. 
     Preferably, each striking area comprises a top, and an extension spirally and outwardly extending from the top. 
     Preferably, the tops of the at least two striking areas are located near the center of the respective striking face. 
     Preferably, the at least two striking areas are equidistantly symmetrically located near the center of the respective striking face. 
     Preferably, a gap is formed between two adjacent striking areas. 
     Preferably, the at least two striking areas are spirally arranged on the breaking portion. 
     Other advantages and features of the present invention will be fully understood by reference to the following specification in conjunction with the accompanying drawings, in which like reference signs denote like components of structure.

     DETAILED DESCRIPTION OF THE INVENTION 
     The technical contents and features of the present invention will now be described hereinafter with reference to the accompanying drawings. Those skilled in the art can understand that the description terms of the preferred embodiment belong to a higher-level description that does not limit the application field of solar power generation modules, for example, hammer head structure or related technical terms include, but are not limited to, the manner specified in the description, the term location includes but is not limited to setting, approaching, connecting, or adjoining, and the number “a” of each component includes one and more than one component number. The directional adjectives such as “up”, “down”, “inside”, “outside”, “top”, and “bottom” mentioned in the contents of this specification are merely illustrative description terms based on the normal use direction, not as the purpose of limiting the scope of the claims. 
     As shown in  FIG. 1  to  FIG. 4 , a breaker hammer for breaking hard objects provided by the preferred embodiment of the present invention is specifically an American sledgehammer as an example. The breaker hammer has a first striking face  10  and a second striking face  20 . The first striking face  10  and the second striking face  20  are respectively disposed at two opposite sides of the head of the breaker hammer. The first striking face  10  of the present preferred embodiment is generally an arc surface, which is mainly used for striking general objects. A handle  50  is provided between the first striking face  10  and the second striking face  20  of the breaker hammer. 
     In the preferred embodiment, the second striking face  20  of the striker hammer is taken as an example with a substantially circular ring edge  22 , and the ring edge  22  may also have other shapes such as a polygon or a special shape, so that the second striking face  20  can adjust the shape according to the actual application status. The second striking face  20  has a breaking portion  24  inside. The breaking portion  24  in the present preferred embodiment is mainly based on a concentric circle region with a predetermined distance retracted from the ring edge  22  toward the inside of the second striking face  20  as an example. The breaking portion  24  occupies approximately 80% of the area of the second striking face  20 . Preferably, the breaking portion  24  may also occupy approximately 60-70% of the area of the second striking face  20 , and the use and impact effects can be more concentrated and efficient. 
     The breaking portion  24  of the second striking face  20  has at least two striking areas  26 , each striking area  26  protruding from the second striking face  20 . Specifically, in the preferred embodiment, four stroking areas  26  are arranged on the breaking portion  24  at an equal distance and symmetrically as an example. Each striking area  26  has a top  30  and an extension  32  spirally extending from the top  30 . The arrangement of the striking areas  26  in the present preferred embodiment is based on the tops  30  of the striking areas  26  being equidistantly symmetrically located near the center of the second striking face  20 . The extension  32  of each striking area  26  extends from the associating top  30  to the ring edge  22  of the second striking face  20 . A gap  34  is formed between the extensions  32  of two adjacent striking areas  26 , and the overall striking areas  26  form a spiral and rotating structure at the breaking portion  24 . 
     With the above-mentioned constituent members, when the second striking face  20  of the breaker hammer is used to strike hard objects such as stone objects, because of the design that each striking area  26  of the breaking portion  24  projects the second striking face  20 , the striking areas  26  can contact the hard objects first. Using the top  30  of each striking area  26  to directly impact the surface of hard objects, the hard objects can be easily broken into pieces by the striking areas  26 . Furthermore, each striking area  26  is centered on the center of the second striking face  20 , which increases the instantaneous destructiveness when struck. The extensions  32  of striking areas  26  can increase the structural strength of striking areas  26  and further increase the destructive force. It can also use the spiral structure of the extensions  32  and each gap  34  to guide the debris generated after the destruction of hard objects to further increase the knock and damage effects of hard objects.
