Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated.
Embodiment:
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, a kind of arc spade that becomes, comprises impact head 10, connecting plate 20, fixing shovel board 30 and activity shovel board 40.The two sides of described connecting plate 20 is respectively the first joint face and the second joint face, vertical being fixedly connected with of the first joint face of one end of described impact head 10 and described connecting plate 20, vertical being fixedly connected with in middle part of one end of described fixing shovel board 30 and the second joint face of described connecting plate 20.The dual-side of described fixing shovel board 30 is hinged with respectively a described activity shovel board 40, activity shovel board 40 ends near described connecting plate 20 are provided with the female bolt hole of tool along the vertical direction of connecting plate 20, and described connecting plate 20 is provided with and matches with described bolt hole movement locus and angle between activity shovel board 40 and fixing shovel board 30 can be limited to the spacing screw 201 of 135 °-180 °.Described activity shovel board 40 is by being fixedly connected with described connecting plate 20 with the screw of bolt hole threaded engagement through spacing screw 201.
