[0021] As one embodiment in the present embodiment, as Figure 3 and Figure 4As shown, the knocking assembly 2 includes two vertical plates 21 fixed symmetrically on the upper end surface of the lifting plate 15, and a rotating rod 22 is rotatably connected between the top portions of the two vertical plates 21. A plurality of fixed sleeves 23 are fixedly sleeved on the outer wall of the rotating rod 22, and a plurality of hitting rods 24 are fixedly connected to the outer walls of the plurality of fixed sleeves 23. The ends of the plurality of hitting rods 24 away from the fixed sleeves 23 are fixedly connected with hitting balls 25. The upper end surface of the lifting plate 15 is provided with a driving assembly 3 for driving the rotating rod 22. In specific use, when the driving assembly 3 is started, it will drive the rotating rod 22 to rotate. Since the fixed sleeves 23, the hitting rods 24 and the hitting balls 25 are fixed on the rotating rod 22, they will move together with the rotating rod 22. When the hitting balls 25 rotate to the position of contacting the metal part, the hitting balls 25 will hit the object.

When the teeth of the driving gear 34 are in meshing connection with the teeth of the incomplete gear 35, it will transmit the rotating force to the incomplete gear 35, thereby driving the rotating rod 22 to rotate. Since the incomplete gear 35 and the driving gear 34 have only part of the teeth, when the teeth of the driving gear 34 are disengaged from the teeth of the incomplete gear 35, the rotating rod 22 will stop rotating. When the teeth of the driving gear 34 are again in meshing connection with the teeth of the incomplete gear 35, the rotating rod 22 will continue to rotate. In this way, the rotating rod 22 will rotate intermittently. With the intermittent rotation of the rotating rod 22, the fixed sleeves 23, the hitting rods 24 and the hitting balls 25 fixed thereon will also move intermittently. When the hitting balls 25 move to the position of contacting the object to be hit, they will hit the object.

[0023] The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit them.
