[0018] Specifically, the top of the lower box body 1 is fixedly connected to the bottom end of the upper box body 4, a rotating pin 6 for rotating the lower jaw plate 5 is provided at the connection between the bottom end of the lower jaw plate 5 and the bottom end of the front face of the upper box body 4, an upper cover plate 7 is provided at the top end of the front face of the upper box body 4, a hinge plate 8 for rotating the upper cover plate 7 is provided at the connection between the bottom end of the upper cover plate 7 and the top end of the front face of the upper box body 4, and a handle 9 is fixedly connected to the top end of the upper cover plate 7.

[0019] Furthermore, the lower box body 1 and the upper box body 4 are fixedly connected by fixing bolts, the rotor 2 is arranged in the middle of the lower box body 1 and the upper box body 4, and the two ends of the upper box body 4 are respectively installed on the top of the lower box body 1 by fixedly connecting bearing seats, and the upper box body 4 is hinged to the lower jaw plate 5 by rotating the pin shaft 6, so that the lower jaw plate 5 rotates about the central axis of the rotating pin shaft 6, and the width of the upper cover plate 7 corresponds to the distance between the opposite sides of the two side plates 10, so that the bottom end of the upper cover plate 7 is attached to the top end of the side plate 10, and the upper cover plate 7 and the top end of the upper box body 4 are hinged by the hinge plate 8. Therefore, when it is necessary to open the upper cover plate 7 to inspect the hammer head 3 and clean the inner walls of the lower box body 1 and the upper box body 4, it is only necessary to pull the handle 9 away from the side plate 10, and the handle 9 drives the upper cover plate 7 to open the upper cover plate 7.

[0020] Specifically, side plates 10 for installing the adjustment mechanism are fixedly connected to both sides of the inner wall of the upper box body 4, and a fixing plate 15 is fixedly connected to one side of the side plate 10. A long expanded hole for inserting the movable bolt 13 is opened at the top of the fixing plate 15, and an adjusting nut 14 is sleeved on the outer wall of the top of the fixing plate 15. The adjusting nut 14 is arranged on the top of the fixing plate 15.
